SPRING  MEETING 

The  Honeywell  Center,  Wabash,  Indiana 

MINUTES  OF  THE  EXECUTIVE  COMMITTEE  MEETING 

April  26,  1968 

The  meeting  was  called  to  order  at  4:30  p.m.  by  Dr.  William  J. 
Wayne,  President  of  The  Academy,  in  the  library  of  the  Honeywell 
Center. 

The  minutes  of  the  Executive  Committee  and  the  General  Session 
of  the  Fall  Meeting  of  The  Academy  held  October  20,  1967  at  Indiana 
University  were  read. 

Treasurer,  Dr.  Frank  A.  Guthrie  reported  Academy  funds  as  fol- 
lows: 

Balance  January  1,  1967  $21,685.67 

Income   for   1967    32,365.22 

Expenditures    for    1967    37,435.45 

Balance,  December  31,  1967 17,568.47 

The  question  of  instituting  an  "Affiliate"  status  for  groups  such  as 
the  Indiana  Chapter  of  the  Society  of  American  Microscopists  was  dis- 
cussed. It  was  generally  agreed  that  there  should  be  no  official  "Affiliate" 
status,  but  that  if  most  of  the  members  of  a  group  were  also  Academy 
members  then  any  meeting  of  the  group  could  be  considered  an  official 
function  of  the  Academy. 

A  motion  was  unanimously  carried  to  accept  Cell  Biology  as  a  full- 
fledged  Division  of  The  Academy. 

Auditing  Committee:  Dr.  Robert  Cooper  reported  the  books  of  the 
Treasurer  to  be  in  good  shape. 

Youth  Activities  Committee:  Dr.  W.  J.  Wayne  reported  that  the 
Science  Search  dinner  was  well  attended. 

Publications  Committee:  Dr.  W.  R.  Eberly  reported  that  the  coming 
Volume  of  the  Proceedings  will  contain  several  innovations  including  a 
complete  list  of  Academy  members  which  will  improve  its  quality.  One 
manuscript  is  now  ready  for  consideration  and  another  in  preparation 
for  the  Special  Publications  Series.  The  Academy  has  agreed  to  support 
this  program,  but  has  not  provided  means  of  funding  the  project.  After 
discussion  by  Frank  A.  Guthrie,  William  A.  Daily  and  Paul  Weatherwax, 
it  was  suggested  that  the  publication  of  the  monographs  might  be  funded 
initially  by  the  John  S.  Wright  Fund  subject  to  approval  by  the  Re- 
search Grants  Committee,  and  that  money  from  the  sales  of  the  first 
monograph  could  be  placed  into  a  regular  publications  fund  so  that  it 
could  become  self-sustaining  eventually.  Dr.  Cleland  suggested  that  W. 
R.  Eberly  and  a  member  of  the  Library  Committee  meet  with  the  Re- 

12 


Minutes  of  the  Executive  Committee  13 

search  Grants  Committee  to  discuss  the  matter.  Dr.  Wayne  agreed  to 
coordinate  such  a  meeting. 

Membership  Committee:  Requests  have  been  made  to  Indiana  Chap- 
ters of  meteorology  and  cell  biology  for  member  lists  in  order  that  Sr. 
M.  Rose  may  send  those  persons  not  already  members  of  The  Academy 
applications  for  membership. 

Scientific  Areas  Committee:  The  following  resolution  was  adopted 
unanimously: 

Whereas  the  fate  of  scientific  and  natural  areas  in  Indiana  is  a 
concern  of  the  Indiana  Academy  of  Science,  and; 

Whereas  this  body  of  men  and  women  believes  it  is  obliged  to 
comment  on  policies  of  land  use  which,  in  its  opinion,  run  contrary  to 
the  best  interests,  both  scientific  and  civic,  of  the  people  of  the  state, 
and; 

Whereas  a  proposed  reservoir  on  Big  Walnut  Creek  in  Putnam 
County,  Indiana,  is  now  planned  which  would  permanently  alter  and 
partially  destroy  a  natural  valley  landscape  on  this  stream,  and; 

Whereas  this  landscape  harbors  an  outstanding  system  of  plants 
and  animals,  including  surpassing  specimens  of  species  which  are  relicts 
of  an  early  post-glacial  flora,  species  unusual  in  their  occurrence,  and; 

Whereas  this  landscape  is  deemed  of  greater  value  in  its  present 
natural  condition,  and  of  greater  long  range  benefit  to  the  people 
of  the  state  as  a  nature  preserve  than  as  a  reservoir  as  now  envisioned, 
and; 

Whereas  several  feasible  alternative  sites  are  reported  to  exist  by 
the  Corp  of  Engineers,  and; 

Whereas  recent  evidence  has  been  submitted  by  the  Indianapolis 
Water  Company  that  future  water  supply  for  that  metropolitan  area 
is  assured  without  said  reservoir  due  to  the  newly  proposed  Mud  Creek 
Reservoir,  thus  negating  one  of  the  major  justifications  for  constructing 
the  disputed  reservoir,  therefore 

BE  IT  RESOLVED  by  the  Indiana  Academy  of  Science  by  action 
of  its  Executive  Committee  this  26th  day  of  April,  1968,  to  stand  op- 
posed to  the  currently  planned  reservoir  on  Big  Walnut  Creek  in  Put- 
nam County,  Indiana,  as  it  is  now  proposed  and  to  continue  to  oppose 
plans  for  any  structure  which  would  result  in  the  inundation  of  any 
part  of  the  natural  valley  landscape  north  of  U.   S.   Highway  36. 

Science  and  Society  Committee:  Dr.  Willis  H.  Johnson  reported 
that  the  speaker's  Bureau  Brochure  was  published  at  a  cost  of  $1000 
provided  by  Eli  Lilly.  The  Progress  in  Government  reported  a  willingness 
on  the  part  of  Academy  members  to  act  in  governmental  matters  in- 
volving science. 


14  Indiana  Academy  of  Science 

An  invitation  from  The  American  Institute  of  Biological  Science 
to  The  Academy  to  become  an  Affiliate  member  was  declined  unani- 
mously. 

Dr.  W.  Wayne  suggested  that  the  fall  meeting  might  include  a 
symposium  in  teaching  of  high  school  science  and  if  sufficient  interest 
subsequently  developed  that  a  division  could  be  added.  Dr.  J.  List  indi- 
cated that  Indiana  Biologists,  a  group  of  teachers  mainly  secondary, 
could  act  as  a  focal  organization.  Dr.  Day  reported  that  a  group  of 
high   school  teachers   of  chemistry  was   being   organized. 

A  motion  was  passed  unanimously  to  change  By-Laws,  Article  I. 
Dues  as  follows: 

Sec.  1.  Initiation  fees,  reinstatement  fees  and  dues  for  the  various 
classes  or  types  of  memberships  shall  be  determined  annually  by  the 
Executive  Committee. 

Sec.  2.  Initiation  fees  are  payable  only  once;  reinstatement  fees  are 
payable  each  time  a  lapsed  membership  is  reactivated.  Annual  dues  are 
based  upon  the  calendar  year. 

Sec.  3.  A  student  discount  in  the  amount  of  50%  of  the  normal  annual 
dues  will  be  awarded  to  undergraduate  and /or  graduate  students  certi- 
fied to  be  eligible  for  this  discount  by  an  Academy  member  on  the 
faculty  of  the  student's  college  or  university.  The  student  discount  is 
limited   to   a   maximum   of   five   years. 

Sec.  4.  Advance  payment  of  annual  dues,  beyond  the  current  year,  may 
be  made  at  the  existent  rate  for  a  period  not  to  exceed  three  years,  or 
in  the  case  of  students  only  through  the  calendar  year  in  which  studies 
should  normally  be  completed,  whichever  occurs  first. 
Sec.  5.  Annual  dues  billings  shall  be  made  by  the  Treasurer  prior  to 
the  spring  meeting.  Delinquent  members  shall  be  rebilled  prior  to  the 
fall  meeting.  Members  delinquent  on  December  20th  shall  be  sent  a 
third  dues  billing  before  December  31st,  and  if  still  delinquent  on 
January  31st  shall  be  dropped  from  the  membership  rolls.  A  former 
member,  dropped  for  lack  of  dues  payment,  may  be  reinstated  by  pay- 
ment of  both  the  reinstatement  fee  and  dues  for  the  year  in  which  he 
wishes  to  resume  membership. 

Sec.  6.  Each  member  is  entitled  to  one  copy  of  the  Proceedings  of 
the  Academy,  and  any  other  publications  of  the  Academy  distributed 
to  the  membership  of  the  Academy,  that  are  published  in  the  year  for 
which  dues  have  been  paid. 

Sec.  7  Former  members  who  were  dropped  for  non-payment  of  dues 
may  obtain  one  copy  of  the  Proceedings,  or  other  publications,  pub- 
lished in  a  year  in  which  they  were  inactive  by  either  of  two  methods, 
provided  copies  are  still  available: 

a.  They  may  pay  the  reinstatement  fee  and  dues  for  the  year  or 
years  of  interest. 

b.  They  may  purchase  one  or  more  copies  at  the  established  non- 
member  price. 

The  meeting  was  adjourned  at  7:00  p.m. 

Approved:  October  18,  1968  James  R.  Gammon,  Secretary

Invitations   Committee — Dr.    Howard  Youse   announced   the   follow- 
ing colleges  as  hosts  for  future  Academy  meetings: 
1969— Hanover  College 
1970 — Indiana  State  University 
1971— Earlham  College 
1972— St.  Mary's  College 

Biological  Survey  Committee — Dr.  Dan  Webster  noted  that  papers 
on  geographic  distribution  of  flora  and  fauna  are  diminishing  while 
ecological  studies  are  increasing. 

Preservation  of  Natural  Areas  Committee — Dr.  Robert  Petty  reported 
that  248  natural  areas  listed  by  counties  is  now  available  upon  request 
on  computer  print-out. 

Committee  on  Science  and  Society — Dr.  Willis  H.  Johnson  reported 
on  the  current  activities  of  the  three  subcommittees. 

The  Speaker's  Bureau  Subcommittee  chaired  by  Dr.  John  Christian 
is  to  be  congratulated  for  their  work  on  the  brochure  containing  the 
names  of  available  speakers  and  topics  which  has  now  been  distributed 
to  nearly  4,000  service  clubs,  women's  clubs  and  high  schools  in  the 
state.  There  is  good  evidence  that  it  is  already  being  used.  A  poll  will 
be  conducted  next  spring  to  ascertain  the  extent  of  usage  and  to  deter- 
mine the  frequency  with  which  the  speakers  have  been  called  upon. 

Dr.  Day  and  the  Subcommittee  on  Science  and  Government  have 
discussed  ways  in  which  the  Academy  might  offer  its  services  to  the 
State  with  Lieutenant  Governor  Rock  and  leaders  of  the  House  and 
Senate.   A  list  of  over  20  subjects  of  interest  to  the  State  was  prepared 


Minutes  of  the  Executive  Committee  17 

and  the  scientists  of  the  state  were  contacted  about  serving  as  con- 
sultants on  one  or  more  of  these  subjects.  More  than  160  scientists 
responded  favorably.  All  legislators  and  legislative  committees  will  be 
informed  of  this  service  and  a  representative  of  the  committee  will 
explain  the  program  to  the  Governor  and  the  Lieutenant  Governor.  Each 
member  of  the  Academy  can  help  further  this  program  by  contacting 
his    senator    and    representative    and    explaining    the    available    service. 

The  Subcommittee  on  Finance  reported  that  efforts  to  obtain  funds 
for  establishing  an  office  with  a  part-time  Executive  Director  and  a 
secretary  have  thus  far  produced  nothing.  A  new  program  of  the  NSF, 
however,  has  indicated  an  interest  and  a  proposal  will  be  submitted 
soon.  It  was  suggested  that  support  might  be  enlisted  from  businesses, 
industries  and  other  organizations  through  a  form  of  institutional  mem- 
bership. Until  outside  funds  are  obtained,  a  continued  budget  of  $416.42 
was  requested  to  continue  work  on  a  limited  scale. 

A  motion  was  approved  directing  the  Science  and  Society  in  con- 
junction with  Dr.  Weatherwax  to  prepare  an  amendment  to  the  Consti- 
tution to  include  an  "Institutional"  membership  to  be  voted  upon  at  the 
spring  meeting. 

Special  financing  was  required  for  the  publication  of  special  ad- 
dresses to  be  distributed  by  the  Science  and  Society  Committee.  A  motion 
was  approved  to  divert  $400.00  toward  their  publication. 

After  thorough  discussion,  a  motion  was  approved  to  move  the  time 
of  the  Fall  Meeting  of  the  Academy  from  Saturday  to  Friday.  A  resolu- 
tion was  passed  that  the  Junior  Academy  of  Science  need  not  change 
their  day  of  meeting  unless  they  wished  to  do  so. 

Dr.  Wayne  suggested  that  a  short  newsletter  be  mailed  to  the 
Academy  membership  shortly  after  the  Spring  Meeting  to  keep  members 
informed  about  Academy  business.  He  also  expressed  the  hope  that  the 
Science  Teaching  Symposium  could  be  continued. 

The  meeting  was  adjourned  at  9:50  p.m. 

Approved  October  20,  1968.

MINUTES  OF  THE  GENERAL  SESSION 

Ball  State  University,  October  19,  1968 

The  annual  Fall  Meeting  of  the  Indiana  Academy  of  Science  was 
held  in  the  Auditorium  of  the  Teachers  College  Building  on  Saturday, 
October  19,  1968,  at  11:00  a.m.  Dr.  William  J.  Wayne,  President,  called 
the  meeting  to  order.  Academy  members  were  officially  welcomed  by 
Dr.  Robert  L.  Carmin,  Dean,  College  of  Sciences  and  Humanities,  Ball 
State  University. 

The  minutes  of  the  Executive  Committee  meeting  held  Friday, 
October  18,  1968,  were  read  by  the  secretary  and  approved  as  read. 

Fay  Kenoyer  Daily  read  a  biographical  sketch  of  each  member  who 
had  died  since  the  1967  Fall  meeting.  These  are  printed  under  Necrology.

Muncie,  Indiana. 

One  hundred  and  fifty-five  students  and  nineteen  sponsors  repre- 
senting seventeen  high  schools  were  registered. 

President,  Dennis  Waltke,  called  the  meeting  to  order  at  2:00  p.m. 
in  the  University  Auditorium.  Previous  to  this  session,  members  of  the 
Junior  Academy  had  enjoyed  tours  and  lectures  in  various  parts  of  the 
campus. 

After  a  joint  luncheon  for  members  of  both  the  Junior  and  Senior 
Academies  in  Cardinal  Hall  at  Pittinger  Student  Center,  the  business 
meeting  was  conducted.  Dennis  Waltke,  president,  introduced  the  other 
officers:  James  Peterson,  Vice-President  and  Rachel  Koontz,  Secretary. 
Dennis  gave  a  brief  welcome.  The  minutes  of  the  1967  meeting  were 
read  and  approved.  Eighteen  papers  were  presented  as  listed  in  the 
program. 

Following  the  presentation  of  the  papers,  the  President  of  the 
American  Society  for  Microbiology,  Indiana  Branch,  Dr.  Stone,  an- 
nounced the  names  of  the  winners  of  the  Society's  awards  for  the  best 
papers  in  microbiology.  Marcia   Stroud  of  Howe  High  School  received

cellular Organization  of  the  Leucine  Specific  Enzymes  in  Salmonella 
typhimurium  CV-19".  Honorable  mention  included  Sam  Combs  and 
Brent  Kern. 

Dennis  introduced  Mr.  Keith  Hunnings  who  introduced  the  new

Timothy  O'Leary,  Vice-President 
Rachel  Koontz,  Secretary 

The  best  boy  award  went  to  Dennis  Waltke,  and  Marcia  Stroud  and 
Rachel  Koontz  tied  for  the  best  girl  award.  Each  received  a  certificate 
of  recognition,  a  year's  honorary  membership  in  the  American  Associ- 
ation for  the  Advancement  of  Science  and  a  year's  subscription  to  Science 
magazine. 

Next  year's  meeting  of  the  Senior  Academy  was  set  for  Saturday, 
October  25,  1969,  at  Hanover  College.  However,  because  of  its  extreme 
southern  location,  a  later  announcement  will  confirm  the  time  and  meet- 
ing place  for  the  Junior  Academy. 

Miss  Helen  Reed  announced  that  she  would  be  distributing  sum- 
maries of  last  year's  papers  directly  following  the  meeting.  The  academy 
extended  its  thanks  for  her  services.

Frederick  John  Allen 
Elgin,  Oregon  Lafayette,  Indiana 

November  21,   1894  June  20,   1968 

Dr.  Frederick  John  Allen  was  a  retired  Purdue  University  Professor 
of  Chemistry  at  his  death  June  20,  1968.  He  was  noted  for  his  research 
in  the  purification  and  properties  of  the  rare  gases,  krypton  and  xenon, 
studies  of  cobalt  and  its  compounds  and  educational  methods  in  chem- 
istry. He  was  in  charge  of  writing  state  tests  of  Indiana  high  school 
chemistry  pupils  for  many  years. 

Born  in  Elgin,  Oregon,  his  early  education  was  obtained  in  that 
state.  A  bachelor  of  science  degree  in  agriculture  was  obtained  from 
Oregon  State  in  1917.  He  came  to  Indiana  then  for  work  at  Purdue 
University  where  he  was  an  assistant  in  chemistry  1917  to  1918  and 
1920  to  1921  when  he  received  an  M.S.  degree.  He  was  an  instructor  at 
Oregon  State  College  from  1919  to  1922  and  at  Purdue  1922  to  1929. 
He  was  an  Assistant  Professor  of  General  Chemistry  from  1930  until 
he  retired  in  1960.  He  served  during  World  War  I  at  the  American 
University  Experiment  Station  in  Washington,  D.  C. 

He  joined  the  Indiana  Academy  of  Science  in  1927  and  was  honored

December  10,  1873  June  9,  1967 

Mr.  John  H.  Armington  was  known  as  "the  dean  of  Hoosier 
weather  forecasters"  for  his  pioneer  work  in  this  field.  Born  in  Leesburg, 
Indiana,  in  Kosciusko  County,  his  schooling  was  obtained  there,  and 
later  he  taught  and  was  principal  of  a  school  there.  He  studied  at  both

Necrology  33 

Valparaiso  and  Tri-State  Colleges,  but  did  not  receive  a  degree.  His 
interest  centered  around  English,  Greek  and  Latin  Courses  in  college. 
In  those  early  days,  a  college  degree  or  special  course  work  was  not 
necessary  for  a  government  job  in  the  Weather  Bureau,  so  in  1902  he 
began  his  career  under  Henry  J.  Cox,  a  weather  forecasting  pioneer 
with  the  Chicago  Bureau.  In  1914  they  were  co-authors  of  a  publication 
of  the  University  of  Chicago  Press  called  "the  Weather  and  Climate 
of  Chicago." 

Mr.  Armington  was  transferred  from  the  U.S.  Weather  Bureau  in 
Chicago  to  the  one  in  Indianapolis  in  1914,  and  had  completed  29  years 
of  forecasting  at  his  retirement  in  1943.  Mr.  Armington  and  his  wife 
celebrated  their  fiftieth  wedding  anniversary  in  1947.  They  had  a  son, 
John  M.,  and  a  daughter,  Mary  E.  Mr.  Armington  was  secretary  of 
the  Indianapolis  Lions  Club  until  the  mid-1950's  and  was  cited  as  its 
outstanding  member  in  1949. 

He  joined  the  Indiana  Academy  of  Science  in  1921  and  was  interested 
in  the  Geology  and  Geography  Sectional  Meetings.  He  presented  a 
paper  on  "City  Smogs  in  Periods  of  General  Fair  Weather"  in  1924  and 
served  on  the  Library  Committee  for  1931  to  1932. 

Mr.  Armington  enjoyed  a  long  and  productive  life  reaching  93  years 
of  age  before  his  death  at  home,  June  9,  1967. 


Everett  Tyler  Burton 
Brook,  Indiana  Battle  Creek,  Michigan 

April  21,  1893  October  21,  1967 

Everett  Tyler  Burton  was  born  in  the  small  town  of  Brook,  Indiana, 
April  21,  1893.  His  education  was  obtained  in  Indiana  receiving  a  B.A. 
and  M.A.  degree  from  Indiana  University  in  1920  and  1924  respectively. 
He  also  attended  Columbia  University.  During  1917  and  1918,  he  was  a 
civil  engineer  with  the  U.S.  Army  serving  in  France.  He  became 
a  second  lieutenant.  He  was  a  research  engineer  for  the  Bell  Telephone 
Laboratories,  New  York,  from  1920  to  1955.  After  retirement,  he 
moved  to  Battle  Creek,  Michigan,  where  he  was  a  registered  engineer  and 
consultant  at  the  Research  Institute  of  Michigan. 

He  joined  the  Indiana  Academy  of  Science  in  1920  while  at  Indiana 
University,  but  moved  within  the  year  although  his  M.A.  degree  was 
completed  at  Indiana  University  in  1924.  Then  later  he  resided  at 
Battle  Creek,  so  was  an  out-of-state  member  most  of  the  48  years 
of  membership. 

Mr.  Burton  also  belonged  to  the  American  Association  for  the 
Advancement  of  Science,  Society  of  Military  Engineers,  Institute  of 
Radio  Engineering,  Bell  Telephone  Pioneers  and  was  active  in  the

Mable  Henniger  Esten 
Anderson,  Indiana  Indianapolis,  Indiana 

October  14,  1898  February  29,  1968 

Mable  Marie  Esten  nee  Henniger  was  born  October  14,  1898, 
near  Anderson,  Indiana.  She  attended  rural  public  schools  and  graduated 
from  Anderson  High  School  in  1916.  She  graduated  from  Butler  Univer- 
sity in  1922  and  obtained  an  M.A.  degree  in  1932. 

She  taught  English  and  Spanish  Courses  at  Anderson  Junior  High 
School  from  1922  to  1924.  During  this  period,  she  met  and  married 
Sidney  R.  Esten  who  also  taught  at  Anderson  High  School.  A  daughter, 
Virginia,  was  born  in  1924.  Both  Sidney  and  Virginia  have  also  been 
Indiana  Academy  of  Science  members.  Sidney,  deceased,  was  a  high 
school  biology  teacher  and  Virginia  teaches  in  an  Indinapolis  High 
School  now. 

Due  to  Sidney's  influence,  Mable  became  interested  in  Botany  and 
majored  in  this  subject  during  graduate  study  at  Butler  University. 
She  had  taken  classwork  at  Indiana  University  while  Sidney  returned 
to  that  school  for  study.  She  also  gave  lectures  and  led  nature  hikes 
at  Turkey  Run  State  Park  from  1927  to  1933.  Sidney  was  naturalist 
there  for  the  Department  of  Conservation. 

Following  graduate  work,  Mable  Esten  became  an  instructor  in 
the  Evening  Division  of  Butler  University  in  1932.  She  continued 
teaching  both  in  the  day  and  evening  classes  until  1953.  She  returned 
to  teaching  in  1958  in  the  Botany  Department  of  DePauw  University 
and  taught  until  1961. 

Both  Sidney  and  Mable  were  enthusiastic  naturalists  carrying  their 
professionl  interests  into  their  leisure  hours.  Both  were  energetic  col- 
lectors with  Mable's  specialty  emphasizing  button  collection  showing 
botanical  designs  and  mythical  animals.  Her  activities  in  this  field  won 
much  acclaim  and  occupied  considerable  time  after  her  retirement.  She 
was  editor  of  the  Button  Box,  a  button  society  publication,  president 
of  the  Indianapolis  and  Indiana  button  societies,  author  of  several 
articles  in  this  field  and  lectured  both  locally  and  nationally.  After  her 
husband  retired,  they  both  contributed  valuable  material  to  the  dictionary 
of  natural  sciences  published  in  1966  by  the  Compton  Co.,  Division  of 
the  Encyclopedia  Britannica,  Incorporated. 

Mable  first  joined  the  Indiana  Academy  of  Science  in  1931.  Although 
her  membership  was  not  continuous,  she  belonged  many  years  and  con- 
tributed papers  to  the  programs.  She  reported  on  the  ''Beech-Maple 
Association  at  Turkey  Run  State  Park"  in  1931  and  gave  a  joint  paper 
with  Albert  G.  Dannin  on  chlorophyll  therapy  in  1949.

Mable  Henniger  Esten  was  honored  by  election  to  Phi  Kappa  Phi, 
national  honorary  society,  and  was  a  past  president  of  the  Indianapolis 
Alumni  Club  of  Phi  Kappa  Phi. 

Mable  died  quietly  in  her  sleep  February  29,  1968,  after  suffering 
a  heart  attack,  one  of  a  series  over  the  past  several  years.  Despite  ill 
health,  she  had  remained  active  and  a  cheerful,  gracious  friend.

Mr.  Louraine  had  been  a  member  of  the  Indiana  Academy  of  Science 
44  years  at  the  time  of  his  death  even  though  he  had  resided  elsewhere 
most  of  the  years  of  membership.  The  field  trips  which  he  attended 
at  Marengo  Cave  in  1924,  the  year  he  joined  the  society,  and  the  next 
year  at  Madison,  Indiana,  had  made  a  lasting  impression  on  him.  Many 
years  later,  he  recognized  Dr.  Paul  Weatherwax  on  a  visit  to  the 
Library  of  Congress  and  recalled  these  meetings  with  considerable 
pleasure.  Frank  Louraine  was  a  fine  librarian  and  graciously  accommo- 
dated scholars  seeking  reference  material.  His  services  were  sincerely 
appreciated. 

Roy  McKee 
Jonesboro,  Indiana  Gas  City,  Indiana 

August  17,   1903  June   14,   1967 

Roy  McKee  was  an  excellent  teacher  at  the  Mississinewa  High 
School  in  Gas  City,  Indiana,  and  was  a  leader  in  the  public  affairs 
of  his  community.  He  was  honored  at  his  death  by  resolutions  from  the 
Mayor  and  Common  Council  of  that  city  praising  his  work  as  Civil 
Defense  Director,  chairman  of  the  committee  which  organized  the  Gas 
City  Plan  Commission  and  Gas  City  Board  of  Zoning  Appeals,  and  his 
service  on  the  Plan  Commission  after  organization.  In  resolutions 
adopted  by  the  Mississinewa  Board  of  School  Trustees,  his  outstanding 
leadership  during  37  years  as  teacher  and  community  leader  was  recog- 
nized. Appreciation  was  expressed  for  his  untiring  energy,  great  insight, 
rare  force,  fine  tact  and  love  of  culture  and  the  beautiful. 

He  was  born  at  Jonesboro,  Indiana,  August  17,  1903,  where  he 
attended  public  school.  He  attended  Indiana  University  and  graduated 
from  Marion  College  with  a  B.S.  degree  in  1931.  He  also  attended 
Purdue  and  Ball  State  Universities. 

Roy  McKee  joined  the  Indiana  Academy  of  Science  in  1932  and 
was  interested  in  the  Chemistry,  Botany  and  Zoology  Sections.  He 
was  a  sponsor  in  the  Junior  Academy  of  Science  for  the  Gas  City 
Science  Club  for  several  years  after  its  organization  in  1936.  He 
served  as  member  of  the  Council  of  the  Junior  Academy  of  Science 
from  1944  to  1948.

Millard  S.  Markle 
Wayne  County,  Indiana  Richmond,  Indiana 

November  26,  1883  October  31,  1968 

Dr.  Millard  S.  Markle  was  almost  85  years  of  age  when  he  died 
October  31,  1968.  His  membership  in  the  Indiana  Academy  of  Science 
had  extended  over  58  years,  a  record  seldom  equalled.  He  had  been 
a  fellow  in  the  society  for  over  fifty  years  and  was  quite  active  until 
his  death.  He  had  attended  the  Executive  Committee  Meeting  on  October 
18  and  was  a  participant  in  the  Botany  field  trip  in  the  spring  of 
1968,  when  he  was  as  always  affable  and  helpful.  He  presented  an 
invited  paper  at  the  Academy  on  the  history  of  Plant  Taxonomy  and 
Ecology  in  Indiana  in  celebration  of  Indiana's  Sesquicentennial  year, 
1966.  As  the  editor  stated,  the  authors  selected  to  give  papers  during 
this  celebration  were  chosen  because  they  knew  Indiana's  history  best 
and  helped  make  some  of  it  as  well  as  write  about  it.  Dr.  Markle 
presented  many  papers  before  the  Academy  on  a  variety  of  subjects 
including  plant  abnormalities,  plant  ecology,  microtechnique,  botanical 
travel  reports,  teaching  bacteriology,  and  several  historical  articles.  He 
was  President  of  the  Indiana  Academy  of  Science  in  1945.  His  presi- 
dential address  was  entitled  "Biology  and  the  Post  War  World." 

On  November  26,  1883,  Millard  S.  Markle  was  born  in  Franklin, 
Wayne  County,  Indiana.  This  town,  5  miles  north  of  Hagerstown,  no 
longer  exists.  He  later  lived  in  Daviess  County  and  attended  school  at 
Washington,  Indiana.  An  early  interest  in  science  developed  at  high 
school  while  taking  physiology.  In  the  spring  of  1904,  he  was  allowed 
to  enter  Earlham  College  before  his  graduation  from  high  school.  This 
was  to  enable  him  to  attend  college  and  teach  in  public  schools  in  the 
fall  and  winter  terms.  He  received  his  B.S.  degree  in  1910  after  being 
tutored  to  satisfy  high  school  requirements.  Some  high  school  credit 
was  also  received  for  teaching  at  Tipton,  Webster  and  Green  Forks 
where  he  was  superintendent  of  schools.  He  had  also  attended  Indiana 
State  Normal  from  1901  to  1902.  He  taught  a  year  at  Earlham  and 
then  attended  graduate  school  at  Chicago  University  receiving  an  M.S. 
degree  in  1913  and  a  Ph.D.  degree  in  1915.  Dr.  Markle's  teaching  career 
at  Earlham  continued  during  graduate  school  years.  He  was  Assistant 
in  Biology  from  1909  to  1910,  instructor  from  1910  to  1912,  Assistant 
Professor  from  1912  to  1915,  Professor  of  Botany  from  1915  to  1918, 
Professor  in  the  newly  formed  Biology  Department  from  1918  to  1954, 
and  was  Emeritus  Professor  from  1954  to  1968. 

Dr.  Markle  contributed  many  illustrated  lectures  at  the  Indiana 
Academy  of  Science  meetings  before  the  Plant  Taxonomy  Section.  His 
beautiful  color  slides  for  projection  were  gleanings  from  interesting 
field  trips  and  travel  sequences.  One  source  of  color  photographs  came 
from  a  program  for  practical  instruction  on  field  trips  introduced  by 
Dr.  David  Worth  Dennis  at  Earlham.  Dr.  Markle  continued  this  policy 
with  annual  trips  for  students  to  the  Smokey  Mountains,  Georgia  and 
Florida.  He  also  visited  our  nation's  national  parks,  Europe  and  Canada.

He  had  just  visited  Africa  the  summer  of  1968  shortly  before  his 
death.  He  also  spent  much  time  before  and  after  retirement  on  the 
preparation  of  microscope  slides  containing  materials  for  use  in  teach- 
ing biology. 

Dr.  Markle  was  honored  and  received  positions  of  trust  by  the 
action  of  several  other  societies  during  his  career.  He  was  Fellow  of 
the  American  Association  for  the  Advancement  of  Science,  President 
and  Director  of  the  Indiana  Audubon  Society,  President  of  the  Rich- 
mond Audubon  and  Nature  Club,  President  of  the  Richmond  Photo- 
graphic Society,  and  was  Superintendent  of  the  Sunday  School  at 
the  West  Richmond  Friends  Meeting.  Biographical  material  appears 
in  American  Men  of  Science,  Indiana  Scientists,  Who's  Who  in  Indiana 
for  1957  and  the  Earlhamite. 

Memorial  services  at  a  West  Richmond  Friends  Meeting,  November 
10,  1968,  gave  testimony  to  the  stature  of  this  man.  His  appreciation  of 
good  music,  good  friends  and  his  responsiveness  to  other's  needs  were 
recognized.  His  gentle  but  forceful  life  was  an  inspiration  to  his 
fellow  men  and  will  long  be  remembered  by  those  fortunate  enough 
to  know  him. 

Neal  R.  Merritt 
Pawnee   City,  Nebraska  Wabash,  Indiana 

July  18,  1899  June  9,  1968 

Neal  R.  Merritt  was  an  Associate  Professor  of  Geology  and 
Geography  at  Manchester  at  his  death  June  9,  1968.  There,  he  had 
attained  a  unique  popularity  by  building  a  workshop  next  to  his 
home  in  Manchester  in  the  shape  of  a  Dutch  windmill.  He  covered 
it  with  various  kinds  of  rocks  collected  on  his  and  Mrs.  Merritt's 
travels  over  the  United  States,  Mexico,  Canada  and  Europe.  The 
rocks  created  much  interest  among  his  students  and  with  his  excellent 
teaching  ability  generated  great  popularity  for  his  courses. 

Prof.  Merritt  was  bom  at  Pawnee  City,  Nebraska,  July  18,  1899, 
but  moved  to  Minnesota  where  he  graduated  from  high  school  at 
Hinckley  in  1916.  He  specialized  in  social  science  and  English  in  his 
undergraduate  study.  He  attended  Duluth  State  Teachers  College  in 
1937,  received  a  B.S.  degree  from  Bemidji  State  Teachers  College  in 
1941,  B.A.  in  1952.  He  received  an  M.A.  from  the  University  of  Minne- 
sota in  1950  where  he  had  attended  the  summers  of  1946  to  1950.  He 
also  studied  science,  Spanish  and  the  humanities  at  Manchester  College. 
His    graduate   work   was    in   political    science,    history   and   education. 

Neal  R.  Merritt  was  a  rural  school  teacher  in  Pine  County,  Minne- 
sota, from  1917  to  1936.  During  this  time  he  was  married  and  had  two 
children.  He  was  a  grade  school  principal  of  Indian  School,  Onigum, 
Minnesota,  from  1937  to  1941;  high  school  teacher  and  principal  at 
Walker,   Minnesota,  from   1941   to   1946;   history   teacher   and   Dean   of

membership  longer  than  two  years. 


Frank  N.  Wallace 
Chicago,  Illinois  Washington,  D.C. 

August    9,    1878  May    24,    1968 

Frank  N.  Wallace,  former  Indiana  State  Entomologist,  died  May  24, 
1968,  at  Washington,  District  of  Columbia,  where  he  had  moved  in 
1961.  His  great  ability  and  the  affection  with  which  he  was  regarded 
contributed  to  a  career  unparallelled  in  this  state.  He  had  been  state 
entomologist  for  43  years  under  both  Republican  and  Democratic  ad- 
ministrations when  he  retired  in  1958.  He  did  more  to  publicize  the 
Department  of  Conservation  than  any  living  person,  and  was  a  pioneer 
in  developing  the  state  park  system  in  Indiana  by  working  with  Col. 
Richard  Lieber.  He  was  ever  alert  to  new  ways  of  making  our  Indiana 
parks  more  enjoyable  to  visitors,  and  publicized  them  by  giving  illustrated 
lectures  on  their  many  assets.  His  sharp  Scottish  wit  and  engaging 
humor  were  resourceful  in  obtaining  support  in  the  press  and  among 
politicians  for  his  programs.  In  1955,  Frank  N.  Wallace  was  awarded 
a  certificate  by  then  Governor  George  N.  Craig  for  "outstanding  devo- 
tion to  duty." 

Mr.  Wallace  was  born  in  Chicago,  Illinois,  August  9,  1879.  He 
came  to  Indianapolis  with  his  family  when  he  was  a  small  child.  He 
first  attended  school  in  this  city  where  the  downtown  post  office  now 
stands  on  the  northeast  corner  of  Ohio  and  Meridian  Streets.  He  had 
nearly  finished  high  school  when  he  took  a  bookkeeping  job  and  con- 
tinued his  education  in  accounting  at  the  Y.M.C.A.  It  was  this  train- 
ing that  opened  the  opportunity  for  his  career  in  entomology.  Ben 
Douglas,  then  state  entomologist,  asked  Mr.  Wallace  to  straighten  out 
the  accounting  for  his  office.  Under  tutorship  of  Mr.  Douglas,  Frank 
Wallace  became  an  authority  on  insect  life.  When  the  Indiana  Depart- 
ment of  Conservation  was  established  in  1919,  Mr.  Wallace  was  made 
the  Division  of  Entomology  Director  as  State  Entomologist.  In  1956, 
Mr.  Wallace  was  awarded  an  honorary  doctor  of  laws  degree  by  Indi- 
iana  Central  College.

FRANK  N.  WALLACE 
1878-1968 


42  Indiana  Academy  of  Science 

Few  persons  have  lived  a  more  colorful  life  than  Mr.  Wallace. 
When  he  was  a  young  man,  he  went  to  northern  Indiana  to  work 
on  some  trees  for  Gene  Stratton  Porter,  the  noted  authoress.  It  was 
there  that  he  met  her  secretary,  Lorene  Miller,  whom  he  married.  They 
had  one  son,  John  H.  Wallace,  Vice-president  of  the  Lausche  Instrument 
Company,  now  living  in  Washington,  D.C.  Mr.  Wallace  traveled  widely 
in  the  state  and  country  in  pursuit  of  his  profession. 

Frank  Wallace  joined  the  Indiana  Academy  of  Science  in  1920,  was 
made  Fellow  in  1937  and  Emeritus  Member  in  1966.  He  served  on 
the  Relation  of  the  Academy  to  State  Committee  from  1924  to  1961,  and 
he  was  chairman  of  the  committee  most  of  that  time.  He  has  the  sincere 
gratitude  of  the  society  for  insuring  publication  funds  for  the  Proceed- 
ings during  some  very  difficult  years  when  the  state  budget  was 
trimmed  severely.  He  was  President  of  the  Indiana  Academy  of  Science 
in  1940.  His  presidential  address  on  Japanese  beetle  control  in  Indiana 
touched  on  a  subject  for  which  he  was  commended  for  significant  con- 
trol measures  in  this  field.  His  work  in  eradication  of  the  beetle  saved 
the  state  thousands  of  dollars.  He  also  achieved  a  significant  victory 
over  the  European  corn  borer  which  inflicted  heavy  losses  before  it 
was  brought  under  control. 

In  addition  to  the  Indiana  Academy  of  Science,  Mr.  Wallace  was 
also  a  member  of  the  American  Association  of  Economic  Entomologists, 
Portfolio,  Masonic  Lodge  and  the  Indianapolis  Press  Club.  He  is  listed 
in  Indiana  Scientists  and  is  the  subject  of  articles  in  the  Indianapolis 
Star  (Dec.  19,  1957),  Outdoor  Indiana  (June,  1958),  and  the  Eastern 
Indiana  Farmer  (November,  1958).

Muncie,  Indiana 
October  19,  1968 


The  address,  "Urban  Geology — A  Need  and  A  Challenge", 
was  presented  by  retiring  president,  Dr.  William  J.  Wayne,  at 
the  annual  dinner  meeting  of  the  Academy  at  the  Pittenger 
Student  Center  on  Saturday  evening,  October  19,  1968.  It  is 
an  excellent  statement  of  the  necessity  of  including  geological 
knowledge  in  many  phases  of  urban  planning.  Dr.  Wayne  is 
currently  a  member  of  the  Department  of  Geology  of  the  Uni- 
versity of  Nebraska.  The  address  by  Dr.  Robert  E.  Gordon, 
Professor  of  Biology  and  Associate  Dean  of  the  College  of 
Science  at  the  University  of  Notre  Dame,  was  given  at  the 
luncheon  meeting  on  October  19  involving  both  the  Junior 
and  Senior  Academy  members.  His  subject,  "Science,  Com- 
munication, and  the  Critical  Mass",  deals  with  the  public 
understanding  of  science  as  a  function  of  the  ability  and 
effectiveness  of  the  scientist's  communication  with  the  public. 


PRESIDENTIAL  ADDRESS 


Urban  Geology — A  Need  and  A  Challenge1 
William  J.  Wayne- 

The  Scope  of  Urban  Geology 

Every  use  man  makes  of  land  is  affected  by  the  shape  of  the  land 
and  by  the  physical  properties  of  the  materials  that  lie  beneath  the 
surface.  He  depends  on  either  the  surface  or  the  materials  beneath  it 
for  food,  water,  and  fuel;  for  building  sites,  building  materials,  and 
foundation  support;  for  waste  disposal;  and  for  recreation. 

Geology  is  the  study  of  the  earth.  It  encompasses  investigation  of 
the  surface,  the  materials  beneath  the  surface,  and  all  the  natural 
processes  that  have  produced  those  materials  and  landforms.  Environ- 
mental geology  is  one  of  the  names  currently  in  vogue  for  the  specific 
phase  of  geology  that  deals  with  the  interrelationships  of  geologic 
processes,  earth  materials,  and  the  ways  in  which  man  has  met  and 
used  this  part  of  his  environment. 

Where  man  has  congregated  in  large  numbers  and  most  extensively 
disturbed  natural  conditions  is  where  most  of  the  conflicts  between  man 
and  his  environment  are  likely  to  take  place.  Thus  the  geology  of  man's 
environment  becomes  most  important  in  and  near  urban  centers;  the 
term  urban  geology  is  virtually  synonomous  with  environmental  geology. 
Urban  geology  involves  the  recognition  and  understanding  of  those 
geologic  processes  that  continuously  work  to  bring  conditions  on  the 
earth's  surface  toward  a  state  of  equilibrium — the  natural  forces  that 
operate  more  or  less  slowly  but  are  powerfully  effective  in  the  creation 
of  landscapes  and  the  disruption  of  some  of  man's  works  on  those  land- 
scapes. 

Our  population  has  increased  greatly  in  recent  decades,  and  with 
that  population  increase  our  intensive  uses  of  land  have  also  expanded 
greatly.  Because  of  this  expansion  and  the  resulting  elimination  of  open 
space  surrounding  urban  centers,  we  find  ourselves  having  increasingly 
less  freedom  to  make  mistakes  in  the  development  of  land  for  uses  more 
intensive  than  farming. 

When  an  error  is  made  in  developing  a  homesite  in  a  rural  environ- 
ment, rarely  is  more  than  a  single  structure  and  one  family  affected; 
an  error  of  similar  magnitude  in  developing  homesites  in  an  urban 
environment,    however,    can    involve    many   dwellings    and   cause    incon-

venience  and  unnecessary  expense  to  many  families.  It  is  therefore  in 
and  near  cities — the  areas  of  large  population  concentrations — where  it 
is  of  greatest  importance  that  the  men  who  guide  our  changes  in  land 
use  recognize  the  ways  in  which  natural  forces  act  upon  natural  ma- 
terials and  upon  the  works  of  man.  The  failure  to  recognize  potentially 
destructive  geologic  processes  can  lead  to  unnecessary  expenses  in  the 
urban  and  urbanizing  areas  for  engineering  works,  costly  damage  to 
structures,  and  perhaps  even  the  loss  of  human  lives. 

Less  spectacularly,  damage  may  be  to  health,  or  may  be  limited  to 
the  inconvenience  of  wet  basements  or  backed  up  drains.  Nevertheless, 
as  man's  use  of  land  expands,  the  need  to  have  a  complete  and  thorough 
knowledge  of  the  geology  of  his  environment  becomes  continuously  more 
important.  The  costs  of  correcting  mistakes  increase  many  fold  after 
available  open  land  has  been  used  up. 

In  comprehensive  planning  for  the  future  development  of  a  com- 
munity, all  the  needs  and  interests  of  the  area  must  be  inventoried  and 
evaluated.  Ideally,  potential  problems  should  be  forseen  early  in  the 
planning  process  so  that  they  can  be  adequately  handled  in  the  ordi- 
nances— zoning  and  others — that  make  planning  effective.  One  basic 
phase  of  a  comprehensive  planning  study — and  one  that  is  often  neglected 
— is   an    evaluation   of   the   geologic   resources    of  the   planning   area. 

The  Role  of  a  Geologist 

Geologists  are  well  equipped  to  contribute  to  several  aspects  of 
comprehensive  studies  in  which  conflicts  of  land  use  frequently  arise. 
Unfortunately,  geologists  are  sometimes  asked  to  help  explain  the  cause 
of  a  problem  that  might  have  been  prevented  if  they  had  been  consulted 
before  the  land  was  developed.  They  often  find  themselves  cast  in  the 
role  of  trouble  shooters  and  pessimists  rather  than  advisors  who  can 
advance  constructive  suggestions  that  will  help  determine  the  optimum 
use  of  available  land. 

Application  of  geologic  study  to  urbanizing  environments  requires 
the  ability  of  a  generalist  who  is  particularly  well  versed  in  geomorphol- 
ogy,  engineering  geology,  economic  geology,  and  hydrogeology,  and  who 
also  has  an  understanding  and  appreciation  of  the  principles  and  admin- 
istration of  land-use  planning.  And  he  must  be  able  to  make  the  results 
of  his  geologic  studies  readily  understandable  to  and  usable  by  the  non- 
geologically  trained  professional  planners  and  citizens  of  the  community 
to  whom  the  decisions  regarding  urban  development  are  entrusted. 

Reports  on  urban  geology  should  include  a  brief  but  adequate 
review  of  the  general  geologic  features  of  the  area  for  which  the  report 
is  prepared  (31).  The  report  must  be  directed,  though,  toward  specific 
geologic  phenomena  that  are  likely  to  be  of  concern  in  planning  the 
community.  Features  of  the  land  about  which  geologists  are  especially 
well  qualified  to  supply  knowledge  and  evaluation  are:  (1)  economic 
mineral  resources  and  potential;  (2)  geologic  conditions  that,  if  un- 
recognized,  could   become    hazards   to    property    or   health;    (3)    water-

supply  potential;   (4)  waste-disposal  sites;  and  (5)  geologic  significance 
of  outstanding  scenic  and  educationally   stimulating  natural  areas. 

Mineral  Resources  that  Serve  Urban  Development 

Mineral  resources  that  are  used  extensively  in  construction,  such 
as  sand,  gravel,  and  crushed  stone,  must  be  exploited  close  to  their 
markets  (Fig.  1).  These  resources  have  a  large  bulk  and  low  value  per 
ton  and  are  generally  surface  mined.  Maintenance  of  a  high  quality 
supply  at  a  low  delivered  price  is  important  to  the  growth  of  every 
expanding  urban  area.  To  keep  construction  costs  low  haulage  distances 
for  aggregates  must  be  short,  because  much  of  the  final  delivered  price 
is  the  cost  of  hauling  (9,  24,  25).

operation  is  almost  completely  surrounded  by  urban  land  uses.  A  worked- 
out  part  of  the  pit  not  visible  in  this  photograph  has  been  reclaimed  for 
recreational  uses. 


One  of  the  most  important  pieces  of  information  that  a  community 
should  include  in  a  comprehensive  planning  study  is  a  map  showing  the 
distribution  of  potentially  workable  reserves  of  mineral  resources.  It  is 
of  no  value  to  permit  mineral  extraction  from  land  that  has  no  mineral- 
resource  potential,  yet  to  restrict  the  industry  from  land  that  does.  Only 
after  the  availability  of  the  resource  is  known  can  a  planner  evaluate  a 
particular  area  of  a  surface  mineral  resource  and  recommend  a  zoning 
ordinance  that  reflects  that  evaluation.  Such  a  study  was  prepared  for 
Marion  County,  Indiana,  in  1958  (12)  as  a  by-product  of  a  county 
mapping  project  (13)  and  was  used  in  designing  zoning  regulations  for 
the  county.

Among  the  major  objections  voiced  by  residents  of  many  com- 
munities to  the  opening  or  continued  operation  of  gravel  pits,  clay  pits 
or  crushed  limestone  quarries  are  the  traffic,  the  dust  of  processing,  the 
noise  and  rocks  of  blasting,  and  the  resulting  wasteland  they  must  live 
with  after  the  resource  has  been  worked  out  (26).  Some  mineral-resource 
operators  have  become  increasingly  aware  of  this  criticism  in  recent 
years,  and  many  of  them  are  becoming  sensitive  to  the  desires  of  their 
communities  that  they  leave  the  worked-out  land  in  a  readily  usable 
condition. 

Mineral  producers  should  be  invited  to  participate  in  the  develop- 
ment of  operating  standards  to  control  traffic,  noise,  and  dust  that  both 
they  and  their  neighbors  can  accept  and  of  subsequent  land-use  plans 
for  the  area  when  they  leave  it  (1).  The  concept  of  sequential  land  use 
applies  particularly  well  to  the  surface-mined  bulk  mineral  commodities 
used  in  construction.  While  the  deposit  is  being  worked  the  land  can  be 
shaped  according  to  a  predetermined  design,  so  that  it  will  fit  well  into 
a  second  planned  use  after  the  resource  has  been  worked  out  and  the 
equipment  removed  (21).  Reclamation  according  to  such  a  plan  is  much 
less  expensive  than  reclamation  after  abandonment.  In  many  places 
the  graded  and  shaped  abandoned  pit  or  quarry  will  have  great  value 
to  the  community  as  a  recreation  site,  or  as  building  lots,  or  an  industrial 
site;  thus  it  can  be  made  into  a  desirable  and  productive  area  rather 
than  a  wasteland  that  remains  an  eyesore  or  health  hazard  (3). 

Natural  Hazards 

Many  millenia  are  needed  for  natural  processes  to  create  landscapes. 
Landscape-producing  forces  work  in  small  increments,  however,  and 
only  small  amounts  of  time  are  required  for  some  of  these  to  take  place. 
The  force  of  earth  or  rock  moving  across  an  unstable  slope  or  of  flood 
water  passing  down  a  valley  is  great,  and  where  the  works  of  man 
happen  to  stand  in  the  way,  they  may  be  damaged  or  destroyed. 

Some  natural  hazards  to  life  or  property  cannot  be  predicted  well 
enough  to  let  us  avoid  them  entirely — the  path  of  a  particular  tornado, 
for  example.  Many  "accidents  of  nature"  that  result  from  failure  to 
understand  some  fundamental  geologic  processes,  however,  can  be  rec- 
ognized by  an  alert  geologist  and  their  potential  for  damage  forecast  so 
that  land  uses  and  construction  standards  can  be  designed  to  reduce  or 
eliminate  the  danger. 

From  the  earliest  of  civilization,  man  has  used  rivers  for  transpor- 
tation, water  supply,  and  waste  removal.  Consequently  he  has  found  the 
land  along  the  rivers  desirable  places  to  build  communities  in  spite  of 
the  knowledge  that  high  water  would  come  regularly;  he  accepted  this 
inconvenience  for  the  advantages  of  being  able  to  use  the  river  the  rest 
of  the  time. 

The  flood  plain,  though,  is  the  domain  of  the  stream  that  built  it.  It  is 
the  relief  valve  of  the  river — the  place  where  the  excess  water  can  spread

out  and  slow  down  when  upstream  areas  and  tributaries  deliver  more 
water  than  the  channel  can  carry.  When  man  forgets  this  or  fails  to 
recognize  it,  he  and  his  works  can  be  damaged. 

We  no  longer  use  any  but  the  largest  rivers  for  transportation.  We 
have,  however,  inherted  the  floodplain  locations  and  have  developed  them 
even  further.  One  of  the  results  of  urban  expansion  on  floodplains  has 
been  an  increasingly  great  property  loss  and  inconvenience  each  time  a 
heavy  runoff  causes  the  land  to  be  inundated.  Increased  urbanization 
upstream  in  the  drainage  basin  also  increases  the  runoff  rate  (11,  19). 
Thus  we  have  had  to  design  and  build  expensive  flood  control  works  to 
protect  our  investments  from  the  inevitable  high  water. 

Flood  plains  are  underlain  by  sediments  dropped  by  a  river  in 
flood.  They  are  a  normal  unit  on  most  geologic  maps;  therefore  their  de- 
lineation is  one  of  the  contributions  of  a  geologic  study  to  the  planning 
process.  Land-use  regulation  that  restricts  construction  of  damageable 
structures  from  areas  of  flooding  is  a  far  less  expensive  way  of  reducing 
future  flood  damage  than  is  building  more  and  bigger  retaining  struc- 
tures and  levees.  Identification  of  flood  plain  land  by  geologic  or  soils 
mapping  permits  it  to  be  zoned  as  future  open  land. 

Gravity  and  water  combine  to  produce  downslope  movement  of 
masses  of  loose  rock  or  soil  on  many  hillsides.  The  degree  of  stability 
or  instability  of  a  particular  slope  is  largely  a  factor  of  both  steepness 
and  moisture  content  and  the  kind  of  material  that  underlies  it.  For 
example,  slopes  of  1:1  are  generally  stable  in  the  mudstones  of  Morgan 
County  and  western  Brown  County,  Indiana;  slopes  of  2:1  are  normally 
stable  in  unweathered  young  glacial  till  of  central  Indiana;  but  slopes 
of  3:1   are   required  for   stability  in  the   thick  weathered   part  of  the

older  glacial  tills  of  southern  Indiana.  Where  unusual  conditions  exist, 
such  as  a  clay  bed  that  serves  to  inhibit  downward  movement  of  moisture 
within  a  sequence  of  silty  glacial  sediments  (Fig.  2),  even  more  gentle 
slopes  may  develop. 

Slopes  that  seem  to  be  stable  under  natural  conditions  may  become 
unstable  if  moisture  content,  loading,  or  steepness  should  be  increased 
through  urban  development.  Such  an  alteration  is  likely  to  result  in 
slumps,  slides,  mudflows  (Fig.  3),  and,  in  areas  of  bedrock,  rock  falls, 
and  rock  slides.  At  the  least,  such  mass  wasting  induced  by  changes  in 
slope  equilibrium  is  likely  to  bring  on  expensive  maintenance  problems, 
such  as  removal  of  debris  from  the  base  of  road  cuts  (Fig.  3)  or  re- 
building retaining  walls.  Where  structures  are  built  on  such  slopes, 
damage  or  destruction  can  be  extensive.  In  addition  to  the  natural 
phenomena  that  can  take  place,  recent  studies  in  Illinois  (34)  have 
shown  that  the  addition  of  detergents,  such  as  those  found  in  laundry 
wastes  and  septic  tank  effluent,  to  unconsolidated  clayey  sediments  will 
decrease  the  strength  of  the  material  and  increase  its  tendency  to  move 
downslope. 

Most  slopes  that  are  likely  to  become  unstable  can  be  recognized 
in  the  field  by  a  geologist  who  is  trained  in  their  evaluation;  the  local 
significance  of  this  natural  process  should  be  reviewed  in  every  geologic 
study  for  land-use  planning  (18,  28).

cumulated  under  conditions  of  ponding  but  are  now  above  water  level 
are  outlined  on  those  geologic  maps  that  show  surface  materials  in 
detail.  Such  sediments  are  unusually  common  in  Indiana  in  resort  areas 
around  the  natural  freshwater  lakes,  as  well  as  in  some  other  parts  of 
the  state  where  bodies  of  water  have  been  completely  filled  by  sedi- 
ments. These  materials  are  not  stable  for  foundations,  and  normal 
construction  procedures  cannot  be  used  if  they  are  developed  intensively 
for  urban  uses.  The  high  water  table  normally  present  would  also 
create  drainage  and  waste-disposal  problems.  Recognition  and  delinea- 
tion of  this  material  in  the  planning  process  is  important  if  the  land 
is  to  be  used  without  danger  or  damage  to  its  occupants. 

Underground  mining  produces  underground  void  space.  Abandoned 
mine  openings  collapse  and  cause  minor  subsidence  at  the  surface.  Maps 
of  underground  mines  on  file  in  the  offices  of  the  Indiana  Geologic 
Survey  provide  for  Indiana  the  kind  of  information  needed  by  planners 
who  would  avoid  such  land  for  construction  until  it  has  again  become 
stable. 

Water  Supply 

An  automobile  in  every  garage  and  electric  power  for  every  home 
made  possible  the  development  of  large  residential  housing  additions 
far  from  the  edges  of  cities  that  would  normally  supply  the  utility  needs 
of  large  numbers  of  families.  Subdivisions  have  been  created  where 
each  home  has  a  private  water  supply  and  an  electric  pump  to  deliver 
the  water  to  the  home.  Not  all  attractive  home  sites  in  Indiana  have 
enough  available  ground  water  to  supply  a  private  home,  though.  And 
construction  of  several  rural  schools  has  been  well  along  before  anyone 
realized  that  some  water  supply  other  than  a  well  drilled  on  the  school 
grounds  would  have  to  be  found  before  the  school  could  open  for  classes. 

An  evaluation  of  the  ground-water  resources  of  the  planning  area 
should  be  included  as  a  part  of  a  comprehensive  plan  and  should  be 
available  for  the  use  of  planning  commissions  in  every  urbanizing  area. 
Hydrogeologic  maps,  which  provide  such  an  evaluation,  can  be  prepared 
by  a  geologist,  using  the  basic  data  derived  from  a  geologic  map  and 
data  on  existing  water  wells.  In  Indiana  generalized  maps  of  this  kind 
suitable  for  county  and  city  planning  purposes  are  being  prepared  by 
geologists  in  the  Division  of  Water  of  the  Department  of  Natural  Re- 
sources (27). 

Not  all  impoundments  hold  enough  water  to  become  ponds  or  lakes. 
Artificial  lakes,  both  large  and  small,  have  been  built  over  materials 
that  allow  the  water  to  leak  out  as  fast  as  it  runs  in  as  well  as  in  places 
that  are  watertight.  A  geologic  report  for  planning  purposes  would  out- 
line those  places  where  high  leakage  rates  could  be  expected  and  areas 
where  lakes  and  ponds  can  be  built  successfully.  Had  such  information 
been  available  and  in  use  by  the  plan  commissions  of  Indiana  cities 
and  counties,  many  investments  and  tax  dollars  of  Indiana  citizens  could 
have  been  saved  during  the  past  quarter  century.

Waste  and  Refuse  Disposal 

Different  geologic  materials  and  the  soil  profiles  developed  on  them 
have  different  capabilities  for  absorption  and  transmittal  of  moisture. 
Although  detailed  planning  for  septic  tank  disposal  fields  probably  is 
better  done  from  a  modern  soils  map  and  field  studies,  broad  aspects  of 
planning  for  on-site  disposal  of  liquid  household  wastes  can  be  done 
readily  from  the  data  available  in  a  geologic  study. 

Movement  of  liquid  wastes  from  the  soil  downward  to  the  water 
table  is  an  aspect  of  sewage  disposal,  though,  that  requires  the  attention 
of  a  geologist.  Surface  water  that  seeps  downward  through  soil  and 
highly  permeable  materials  such  as  sand  or  gravel  and  fractured,  weath- 
ered, or  cavernous  rock  is  likely  to  carry  with  it  surface  contaminants. 
Where  sewage  and  other  liquid  wastes  are  disposed  of  in  the  soil,  some 
of  them  are  likely  to  be  flushed  downward,  particularly  during  periods 
of  heavy  rainfall.  Runoff  from  livestock  feed  lots  is  another  source  of 
concentrated  contaminants  that  has  entered  and  damaged  some  ground- 
water aquifers  in  Indiana. 

In  some  parts  of  Indiana,  where  closely-spaced  houses  depend  on 
both  water  wells  and  septic  tanks,  water  supplies  high  in  coliform 
bacteria  are  not  unusual.  Even  though  the  bacteria  may  be  filtered  or 
have  time  to  die  before  reaching  a  well  intake,  some  wells  have  been 
seriously  affected  by  a  high  nitrate  content,  which  may  cause  illness, 
or  by  other  chemicals  or  detergents  that  manage  to  reach  an  aquifer. 
A  geologic  report  to  a  plan  commission  should  outline  areas  where 
migration  of  liquid  wastes  is  likely  to  damage  nearby  water  supplies. 

Septic  tank  disposal  fields  do  not  all  function  effectively — many  are 
open  to  the  surface.  Nutrients  from  this  effluent  can  cause  very  rapid 
eutrophication  of  lakes  downstream,  as  can  barn  lot  and  pasture  runoff. 

When  solid  wastes  are  made  part  of  the  earth  as  in  a  dump  or  a 
sanitary  landfill,  they  begin  to  undergo  the  same  processes  as  do  natural 
earth  materials.  Some  of  the  rainwater  that  lands  on  the  surface 
permeates  the  earth  and  passes  through  the  soil  and  rocks  on  its  way 
to  a  discharge  area  or  to  the  water  table.  While  it  percolates  through 
earth  materials  it  dissolves  any  substances  that  may  be  soluble  and 
carries  the  leachate  away  as  part  of  the  ground  water.  After  it  migrates 
beyond  the  limits  of  the  landfill  the  leachate  from  a  sanitary  landfill 
can  be  expected  to  behave  as  would  any  vadose  or  phreatic  water  in 
the  same  geologic  environment. 

Our  present  knowledge  about  leachate  migration  is  too  meagre  to 
permit  us  to  speak  in  authoritative  terms,  although  landfills  that  are 
located  in  impermeable  or  slowly  permeable  materials  such  as  shale,  clay, 
or  clayey  till  or  are  separated  geologically  from  an  aquifer  by  such 
materials  probably  are  unlikely  to  cause  any  contamination  of  ground 
water.  Landfills  in  permeable  materials,  though,  particularly  limestone 
or  dolomite,  are  likely  to  yield  a  leachate  that  will  migrate  rather  rap- 
idly and  may  cause  considerable  damage  to  underground  water  sources 


Presidential  Address  57 

(5,  20,  33).  Areas  geologically  favorable  and  unfavorable  for  solid  waste 
disposal  sites  should  be  outlined  in  every  geologic  report  prepared  as 
part  of  a  comprehensive  planning  study  (16). 

Natural  Areas 

Where  people  are,  they  are  expected  to  go  to  school,  and  they  want 
to  recreate.  Many  outstanding  scenic  areas  or  unusual  outcrops  that 
have  geologic  significance  have  been  lost  to  recreation  or  education  be- 
cause they  were  not  recognized  by  those  who  plan  future  land  use, 
although  they  may  have  been  well  known  to  geologists,  ecologists,  and 
naturalists  for  a  long  time.  Some  of  these  areas,  if  the  land  is  to  be 
most  advantageously  used,  probably  should  be  considered  for  preserva- 
tion as  natural  areas  or  for  development  into  park  sites.  The  geologist 
is  remiss  in  his  responsibility  if  he  neglects  to  call  attention  to  such 
areas  so  that  the  planner  can  understand  their  significance  before  they 
have  been  overwhelmed  by  urbanization.  Once  destroyed,  they  cannot 
be  reclaimed  (15). 


Programs  of  Research  in  Urban  Geology 

Less  than  a  decade  ago,  few  geologists  and  fewer  planners  seemed 
to  be  aware  of  ways  in  which  geologic  data  could  be  applied  to  land  use 
problems  (29).  More  recently,  though,  the  United  States  Geological 
Survey  has  recognized  the  need  to  provide  geologic  data  for  use  in  land 
use  planning  (17).  Several  state  geological  surveys,  most  notably  those 
of  California  and  Illinois,  have  also  undertaken  studies  intended  to 
supply  geologic  information  to  planners  (2,  6,  7,  10).  The  Indiana 
Geological  Survey  has  provided  reports  to  a  few  plan  commissions  or 
their  consultants  on  request  during  the  past  decade;  some  of  the  reports 
have  been  published  (8,  12,  30),  and  others  are  available  only  as  file 
reports. 

Some  of  the  data  needed  to  prepare  geologic  reports  for  use  in 
comprehensive  land-use  planning  studies  of  rapidly  urbanizing  parts  of 
Indiana  have  been  acquired  by  Indiana  Geological  Survey  geologists  as 
part  of  other  studies  during  the  past  15  to  20  years.  Several  specific 
new  research  programs  will  be  needed,  though,  if  our  geologists  are 
going  to  be  able  to  answer  the  kinds  of  questions  that  we  can  now 
anticipate.  At  this  time  I  would  like  to  suggest  the  following  program 
of  research  in  urban  geologic  studies  for  Indiana: 

1.  The  preparation  of  county  or  urban  community  geologic  reports. 
— Geologic  reports  must  be  written  specifically  for  use  by  a  city,  county, 
area,  or  metropolitan  plan  commission  that  is  developing  a  compre- 
hensive study  of  its  area  of  jurisdiction  and  must  be  directed  to  that 
audience.  A  standard  geologic  report  does  not  provide  the  needed  in- 
formation without  interpretation.  Table  1  is  an  outline  that  has  served 
well  in  the  preparation  of  such  reports  and  can  be  adapted  to  most 
areas  in  Indiana  and  other  midwest  states.

58  Indiana  Academy  of  Science 

Indiana  Geological  Survey  geologists  have  prepared  several  county 
or  community  reports  at  the  request  of  plan  commissions  or  their 
consultants  during  past  years,  but  many  requests  for  information  were 
received  too  close  to  the  planning  organization's  deadline  to  permit  the 
geologist  to  do  more  than  quickly  draw  together  a  report  based  on 
information  on  hand  but  acquired  for  some  other  purpose.  Unfortunately 
such  reports  will  be  as  variable  in  quality  and  in  value  to  the  user  as 
the  amount  and  quality  of  data  on  hand  for  the  geologist  to  use  in 
their  preparation.  A  special  research  program  could  anticipate  areas 
for  study  far  enough  in  advance  that  most  rush  jobs  could  be  avoided 
when  specific  requests  are  received. 

Geologic  mapping  for  urban  studies  must  be  done  on  as  large  a 
scale  as  is  practicable.  At  one  time,  maps  prepared  at  1  inch  to  1  mile 
(1/63,360)  were  considered  adequate  and  maps  at  1/250,000  and 
1/125,000  were  thought  satisfactory  for  many  purposes.  Urban  studies 
will  require  greater  detail,  however.  California  geologists  are  mapping 
some  urban  areas  on  a  scale  of  600  feet  to  the  inch  (2),  and  the  flood- 
way  mapping  program  of  the  U.  S.  Army  Corps  of  Engineers  is  being 
done  on  an  even  larger  scale. 

County  mapping  for  land-use  studies  probably  will  be  satisfactorily 
presented  on  a  map  with  a  scale  of  an  inch  to  the  mile.  Maps  for  a  pilot 
study  of  Madison  County,  Indiana  are  being  prepared  at  an  inch  to  the 
mile  although  they  were  compiled  at  a  scale  of  1/24,000  (32).  Highly 
urban  areas  as  well  as  complicated  or  problem  areas  probably  should 
be  presented  on  a  larger  scale,  however.  The  study  should  include  a 
basic  map  showing  the  distribution  of  surficial  geologic  units  described 
in  a  non-technical  style  and  must  be  supplemented  by  a  series  of 
geologic  planning  maps  on  which  attention  is  called  to  specific  aspects  of 
geology  as  related  to  land  use  (Table  1).  These  maps  would  include 
waste  disposal,  ground-water  potential,  slope  stability,  economic  ma- 
terials, and  other  subjects  that  may  be  appropriate   (10,  16,  22). 

2.  Geologic  studies  of  ground-water  contamination. — Small  scale 
studies  of  some  wells  in  the  limestone  terrane  of  south-central  Indiana 
a  few  years  ago  led  to  a  recommendation  presented  in  Bulletin  S.  E.  15 
of  the  State  Board  of  Health  that  much  of  the  bacterial  contamination 
of  wells  in  such  regions  can  be  reduced  or  eliminated  entirely  by  a  more 
positive  seal  to  prevent  the  entrance  of  surface  water  and  storm  water 
into  the  open  annular  space  around  the  casing  of  a  well  (Fig.  4).  Re- 
search in  urban  geologic  problems  should  include  additional  studies  of 
this  kind  in  other  geologic  environments,  undertaken  on  the  university 
level  or  cooperatively  by  the  State  Board  of  Health,  Division  of  Water, 
and  the  State  Geological  Survey. 

3.  Migration  of  landfill  leachates. — Although  contaminants  are 
known  to  have  reached  the  water  table  and  to  have  migrated  away  from 
a  landfill  site  under  some  conditions  (4),  few  studies  have  been  under- 
taken to  determine  the  significance  of  different  geologic  conditions  on 
the    movement   of   leachate   from   sanitary   landfills.    Such   a    study   has 


Presidential  Address 


r»«) 


been  proposed  on  a  state  level  in  Indiana,  to  be  done  by  three  state 
agencies  jointly.  Detailed  geologic  and  geophysical  investigation  of  a 
study  area  in  each  of  six  different  geological  environments  will  be  the 
responsibility  of  the  Indiana  Geological  Survey.  A  water  sampling 
program  and  water-quality  analysis  in  and  around  each  pilot  site  and 
the  hydrology  and  evaluation  of  leachate  migration  and  dilution  will  be 
undertaken  by  the  State  Board  of  Health  and  the  Division  of  Water.

Figure  4.  Many  water  wells  in  the  areas  of  shallow  bedrock  in  Indiana 
have  been  completed  without  sealing  the  annular  space  around  the  casing 
of  the  well  to  a  great  enough  depth  to  keep  seepage  of  contaminated 
vadose  water  from  entering  the  hole.  If  the  annular  space  has  been  left 
open  or  has  been  backfilled  loosely  with  soil  or  with  cuttings,  it  remains 
a  conduit  through  which  surface  water  can  drain  downward  rapidly  and 
enter  water-producing  zones.  Wells  in  which  this  space  has  been  filled 
with  cement  grout  or,  under  certain  conditions,  with  thick  drilling  mud, 
and  in  which  the  sealed  casing  extends  downward  far  enough  to  keep 
out  surface  waters  in  permeable  or  cavernous  rock,  are  not  likely  to  be 
damaged  by  polluted  surface  water. 


4.  Reclamation  of  quarried  wasteland. — Worked-out  and  abandoned 
land  from  which  bulk  mineral-industry  commodities  have  been  removed 
is  a  wasteland  near  many  urban  areas.  Unconsolidated  materials,  such 
as  gravel  and  sand,  can  be  reshaped  by  a  subsequent  land  owner  if 
necessary,  but  the  sand  and  gravel  industry  has  started  a  continuing 
program  of  research  to  find  better  and  more  economical  ways  of  pre- 
paring the  land  for  re-use  (14).  Land  underlain  by  consolidated  rocks 
such  as  limestone  are  much  more  difficult  to  reclaim  for  subsequent 
productive  use.  A  study  of  the  rock  properties  that  affect  reshaping 
land  as  well  as  other  possible  techniques  of  converting  worked-out  land

at  a  reasonable  cost  might  reduce  the  time  involved  for  sequential  bene- 
ficial use. 

5.  Damages  from  natural  hazards  of  geologic  origin. — Though  much 
less  spectacular  in  Indiana  than  in  California  (18)  or  Alaska  (23), 
natural  hazards  exist  in  the  state,  and  damages  have  taken  place.  Both 
field  and  laboratory  studies  of  the  geology  and  geometry  of  stable  and 
unstable  slopes  would  help  in  recognizing  the  conditions  that  produce 
instability  of  earth  materials  and  in  predicting  more  accurately  where 
and  under  what  conditions  problems  will  occur  in  each  geologic  environ- 
ment. 

Such  a  research  program  as  this  will  have  to  be  undertaken  as 
soon  as  possible  if  we  are  to  be  able  to  apply  our  geologic  sophistication 
to  aid  in  the  solution  of  these  urban  problems  where  geologic  data  can 
help.  The  longer  we  wait  to  start,  the  longer  we  will  find  ourselves 
forced  to  answer  questions  without  sufficient  information.  If  planners 
are  to  call  on  geologists  for  help,  the  geologists  must  be  in  a  position 
to  supply  it. 


The  Training  of  Geologists  for  Urban  Studies 

As  a  newly-developing  use  of  geologic  information,  urban  geology 
requires  that  the  geologist  limit  his  presentation  and  evaluation  to 
those  aspects  of  geology  that  apply  directly  to  land  use  problems.  It 
is  an  applied  field  of  geology  in  which  the  practitioner  needs  to  under- 
stand not  only  the  geologic  aspects  of  the  problems  but  must  also  be 
aware  of  the  principles  and  techniques  of  the  land-use  planning  profes- 
sion. Until  1967  few,  if  any,  colleges  and  universities  presented  course 
material  to  train  geologists  to  consider  this  field  for  employment.  Some 
of  the  geologists  who  applied  their  knowledge  to  the  solution  of  urban 
problems  had  picked  up  their  background  in  the  needs  of  communities 
through  service  on  local  planning  commissions,  and  others  did  so 
through  encountering  the  problems  in  the  course  of  routine  geologic 
studies  and  becoming  interested  in  solving  them.  Most  frequently  the 
man  was  an  engineering  geologist,  a  ground  water  geologist,  or  an 
economic  geologist. 

Within  the  past  year,  a  few  universities  have  offered  courses  in 
urban  and /or  environmental  geology.  At  Indiana  University  I  presented 
a  series  of  non-credit  evening  lectures  on  the  subject  in  the  spring 
semester  of  1967  and  offered  a  3-hour  credit  course  in  it  in  the  spring 
semester  of  1968.  At  the  same  time  Dr.  James  Hackett  left  the  Illinois 
State  Geological  Survey  to  set  up  a  graduate  program  in  environmental 
geology  at  Virginia  Polytechnic  Institute.  Paul  Hilpman  of  the  Kansas 
Geological  Survey  began  teaching  a  two-semester  course  in  urban 
geology  at  the  University  of  Missouri  in  Kansas  City  in  1967,  and  an 
evening  course  was  offered  at  Oregon  in  the  spring  of  1968.  The  Uni- 
versity of  Nebraska  also  has  just  added  to  its  curriculum  a  one-semester 
course  in  the  subject  to  be  taught  for  the  first  time  in  1969-70. 


Presidential  Address  Gl 

The  Indiana  course,  as  well  as  the  one  to  be  offered  at  Nebraska, 
was  intended  to  introduce  students  to  the  ways  in  which  geologic  data 
can  be  used  to  help  solve  problems  in  land-use  planning.  It  was  designed 
to  follow  a  course  in  physical  geology  and  to  present  the  subject  to 
undergraduate  majors  and  minors  as  well  as  provide  a  course  in  land 
use  applications  of  geology  to  non-majors.  At  Indiana  it  was  especially 
popular  with  graduate  students  in  earth-science  education.  Those  who 
had  completed  and  done  well  in  only  one  course  in  geology  were  able  to 
complete  the  course  successfully,  but  the  amount  of  classroom  partici- 
pation was  directly  related  to  the  geologic  background  of  the  indi- 
vidual students.  No  textbook  exists  that  is  suitable  for  this  course,  but 
the  use  of  selected  readings,  many  of  which  are  cited  here,  provided 
material  that  was  current  as  well  as  appropriate. 

For  a  geology  undergraduate  who  would  like  to  direct  his  pro- 
fessional efforts  into  this  field,  the  normal  B.  S.  requirements  in  geology 
should  be  met  if  possible,  but  electives  would  have  to  include  such 
courses  as  urban  geography,  land-use  planning,  and  other  courses  in 
urban  studies.  It  would  be  possible  at  Indiana  University  to  qualify  for 
a  certificate  in  urban  studies  along  with  a  strong  A.B.  degree  in  geology. 
On  the  graduate  level  a  seminar  in  urban  geologic  problems  coupled 
with  regular  advanced  courses  in  hydrogeology,  economic  geology, 
limnology,  and  engineering  techniques  in  geology  would  provide  the 
required  background  to  become  a  successful  urban  geologist. 

A  non-geologist  who  enters  any  phase  of  land-use  planning  should 
anticipate  the  inclusion  of  a  course  in  urban  geology  about  his  fourth 
year,  after  he  has  acquired  an  adequate  background  in  beginning  geol- 
ogy and  related  courses  in  geography  and  allied  subjects  to  enable  him 
to  master  the  material  presented.  He  would  not,  of  course,  be  trained 
to  make  geologic  studies,  but  should  at  the  conclusion  of  a  course  in 
urban  geology  be  able  to  read  a  geologic  report  with  understanding  and 
to  recognize  the  need  for  a  geologic  study  in  the  planning  process. 


Summary 

Urban  land  uses  are  rapidly  converting  open  land  into  intensively 
used  land.  Generally,  in  planning  those  uses,  a  comprehensive  study  has 
included  everything  except  an  evaluation  of  the  land  in  three  dimensions. 
Geologists  are  eminently  well  equipped  to  supply  the  missing  data,  but 
they  must  also  be  aware  of  the  needs  of  the  urban  community  and  the 
kinds  of  information  needed  by  planners  if  they  are  to  write  reports 
usable  by  planners.  Urban  and  environmental  geology  is  a  newly  ex- 
panding field  in  the  use  of  geologic  data  to  help  solve  some  urban 
problems  in  the  planning  stage.  It  is  likely  to  become  a  part  of  the 
curriculum  in  many  college  geology  departments  within  the  next  few 
years.

Science,  Communication,  and  the  Critical  Mass 

Robert  E.  Gordon 
University  of  Notre  Dame 

In  recent  years,  science  has  been  confronted  with  a  crisis  in  com- 
munication. To  the  average  scientist  this  crisis  has  meant  that  the 
scientist  to  scientist  transfer  of  information  has  bogged  down.  A  number 
of  programs  to  relieve  this  situation  have  been  proposed  and  are,  de- 
pending on  the  field,  in  various  stages  of  implementation. 

I  suppose  that  those  of  you  who  have  followed  the  efforts  of  biology 
to  formulate  a  national  system,  and  know  of  my  activity  in  this  area, 
have  already  concluded  that  a  biologist  is  about  to  speak  to  you  about 
biological  communication. 

Stand  relieved — today  I  wish  to  talk  about  communication — but  not 
that  of  scientist  to  scientist. 

There  is  an  equally  urgent  problem  which  if  not  resolved  may 
have  much  more  deleterious  effects  than  that  posed  within  the  scientific 
community. 

I  refer  to  communication  from  the  scientific  community  to  the  non- 
scientist.  This  problem  is  of  equal  importance  to  all  fields  of  science — 
a  fact  which  is  easily  demonstrable.  A  significant  portion  of  the  long 
range  solution  to  this  problem  rests  in  large  measure  in  the  hands  of 
that  part  of  the  scientific  community  concerned  with  education. 

Previous  to  World  War  II,  research  in  science  was  the  activity  of 
a  dedicated  few — a  relatively  smaller  number  of  practitioners  than  is 
currently  the  case. 

The  public  image  of  research  was  often  revealed  by  caricatures  in 
the  popular  press — in  the  case  of  biology  often  by  a  picture  of  an 
eccentric  old  man  with  collecting  gear  and  butterfly  net.  Indeed,  the 
remarks  of  some  of  my  physical  science  peers  led  me  to  think  that  even 
they  bought  the  image  of  a  biologist,  thus  portrayed. 

With  World  War  II,  the  public  image  took  a  radical  turn.  In  the 
post  World  War  decade,  the  public  image  of  science  and  the  work  of 
scientists  developed  directly  from  the  efforts  of  the  scientific  com- 
munity during  World  War  II. 

And  what  were  these  efforts?  The  more  spectacular  of  them  dealt 
with  the  harnessing  of  nuclear  energy;  the  development  of  radar  and 
sonar;  the  screening  and  selecting  of  chemotherapeutic  agents  such  as 
sulfur  drugs  and  metabolic  by-products  of  fungi  as  antibiotics. 

The  mass  media  publicized  the  work  under  the  label  of  scientific 
research.  Yet  it  is  a  well  known  fact,  at  least  among  scientists,  that  the 
basic  research  behind  these  technological  advances  was  a  product  of 
work  carried  out  by  the  scientists  of  the   1930's  and  earlier.    Further,

we  know  that  the  success  of  the  scientific  community  during  World  War 
II  was  not  the  result  of  directed  research  in  the  1930's.  The  success  re- 
mains as  a  clear  example  of  how  unfettered,  undirected  research  can 
supply  basic  building  stones  on  which  directed  development  and  tech- 
nology can  be  constructed. 

But  these  points  were  never  really  mentioned  to  the  public  and 
hence  their  image  of  science  in  the  post  war  era  was  one  that  can  be 
simply  stated:  given  a  specific  problem,  a  relatively  large  amount  of 
money,  and  an  adequate  concentration  of  investigators,  the  efforts  of 
these  scientists  are  direct  and  result  in  applicable  solutions  to  the 
specific  problem  in  a  remarkably  short  period  of  time. 

Acting  on  this  image,  the  public  stoutly  supported  the  growth  of 
what  was  labelled  in  governmental  budgets — R  and  D — research  and 
development. 

It  is  difficult  to  pinpoint  the  blame  for  this  erroneous  image.  Either 
few  scientists  spoke  loud  enough  with  corrective  statements,  or  the  mass 
media  simply  ignored,  as  non-newsworthy,  disclaimers  from  the  scientific 
community. 

But  the  fact  that  this  image  of  capability  for  immediate  solution 
to  all  problems  confronting  society  became  firmly  entrenched  in  the 
community  at  large  can  hardly  be  disputed. 

With  the  advent  of  spectacular  developments  in  space  by  the 
U.S.S.R.,  a  second  stimulus  for  public  support  of  research  and  de- 
velopment was  layed  upon  the  first.  I  recall  that  academic  salaries  and 
departmental  budgets  increased  dramatically — both  attributable  to  the 
appearance  in  the  stratosphere  of  a  man-produced  and  man-projected 
satellite.  At  this  point,  the  "D"  of  R  and  D  began  to  grow  at  a  rather 
disproportionate   rate  to   its   forerunner  and   counterpart — the   "R". 

The  scientific  community  began  to  speak  out  loud  and  clear  for  its 
share  of  funds  for  basic  research.  Perhaps — for  all  the  wrong  reasons — 
the  public  began  to  think  of  R  and  D  with  some  degree  of  insight 
provided  by  science. 

Growth  of  R  and  D  rose  to  a  rate,  in  dollars  spent,  exceeding  that 
of  our  gross  national  product.  Federal  expenditures  in  research  and 
development  rose  over  a  20  year  period  by  about  25%  each  year.  The 
need  for  scientific  manpower  drew  national  attention.  From  the  first 
grade  through  the  early  years  of  college,  the  academic  portion  of  the 
scientific  community  focused  on  those  individuals  whose  potential 
predicted  a  career  in  science. 

When  one  examined  where  we  were  going  in  the  funding  of 
research  and  development,  even  as  early  as  1958,  a  decade  ago,  the 
answer  was  apparent.  A  simply  extrapolation  of  growth  curves  for  R 
and  D  and  the  GNP  led  Jerome  Wisner,  Science  Advisor  to  President 
Kennedy,  to  inject  the  thought  that  the  bubble  might  burst.  Instead  of 
a  25%  per  year  growth,  leaders  now  talk  about  a  15%  per  year  growth 


Address  67 

— and  15%  is  still  three  times  the  rate  of  growth  of  the  GNP.  The 
problems  of  the  growth  of  science  and  technology  were  apparent  then  a 
decade  ago. 

Congress,  drawing  its  constituents  from  the  public  whose  image 
of  science  was  that  of  immediate  applicability,  began  to  examine  the 
results  of  R  and  D  spending.  This  examination  was  and  still  is  in  terms 
of  the  resolution  today  of  the  multitude  of  problems  facing  the  nation  in 
health,  transportation,  agriculture,  education,  and  urbanization.  No 
consideration  was  or  is  now  being  given  to  the  results  of  governmental 
support  in  terms  of  basic  accumulation  of  knowledge — those  building 
stones  on  which  development  and  technology  rest. 

The  results  of  this  intense  scrutiny  are  familiar  to  you:  the  geol- 
ogists have  lost  Mohole;  funding  for  the  200  BEV  accelerator  at  Weston 
is  slow;  the  chemists  are  frankly  pragmatic  in  stating  that  the  develop- 
ment of  chemistry  as  pictured  in  the  Westheimer  Report  will  probably 
not  be  implemented;  the  IBP  is  stranded  for  lack  of  funds;  and  even 
NIH  in  the  biomedical  domain  has  some  problems.  It  is  true  that  the 
scrutiny  and  the  drastic  cutbacks  are  made  more  intensive  by  our 
involvement  in  Vietnam,  but  I  submit  that  the  bubble  was  due  to  burst 
even  without  Vietnam. 

And  for  those  of  you  who  are  engaged  in  scholastic  education,  a 
reduction  in  the  funding  of  science  at  the  national  level  will  be  followed 
at  the  local  level  with  little  time  lag.  No  one  engaged  in  any  facet  of 
science  in  the  United  States  will  remain  immune  to  the  trend  now  begun. 

Currently,  not  only  research  but  also  development  shares  the  de- 
celeration. Candidly,  I  think  that  if  the  Russians  land  the  Presidium 
on  the  moon,  we — the  scientific  community — may  just  avoid  a  further 
deceleration  likely  to  become  a  decapitation. 

What  is  needed?  Certainly  it  is  not  a  return  to  the  25%  per  year 
increase  in  spending;  the  nation  cannot  afford  it  under  present  or 
projected  economic  conditions.  The  first  need  is  a  planned  steady 
growth  of  research  and  development  more  in  line  with,  and  probably 
hinged  to,  the  5  or  6%  annual  rate  of  growth  of  the  GNP.  Secondly,  a 
more  equitable  distribution  of  these  funds  between  research  and  de- 
velopment must  be  attained,  if  the  generally  accepted  cliche  "what  is 
science  today  is  technology  tomorrow"  is  at  all  correct. 

Are  we  likely  to  achieve  these  two  needs  when  the  war  is  over? 
And  my  answer  is  no,  not  unless  we  effectively  communicate  to  a 
critical  mass  in  the  200  million  people  who  constitute  our  population. 

This  communication  can  occur  at  two  points — one  clearly  a  function 
of  the  educators  present;  the  other,  a  function  of  this  academy  and 
other  institutions  of  organized  science. 

The  two  points  are  fairly  obvious:  initially,  during  the  period  of 
basic  education;  secondly,  as  an  input  in  the  continuing  education  which 
every  adult  in  the  electronic  age  must  carry  out  if  he  or  she  is  to  adjust 
to  the  rapid  advances  of  society  in  this  age.

The  mere  suggestion  that  we  look  at  science  education  conveys  the 
impression  that  there  is  something  amiss.  What  is  it?  The  facts  of 
science  education  as  a  major  vehicle  of  communication  for  the  past 
two  decades  seem  to  fit  the  following  pattern. 

In  the  face  of  the  most  affluent  period  that  science  has  witnessed 
in  any  civilization  since  its  inception,  in  the  face  of  a  demand  for 
scientific  and  technical  personnel — we  began  in  the  elemetary  school  to 
single  out  and  encourage  those  individuals  whose  talents  seemed  bent 
toward  service  of  mother  science. 

We  instituted  science  fairs  at  the  expense  of  the  more  general 
hobby  fair — and  we  achieved  positive  results,  plus  some  negative  ones. 
How  many  students  whose  talents  were  bent  in  another  direction  were 
rebuffed  by  the  emphasis  on  science  ? 

We  put  our  best  teachers  into  advanced  chemistry,  advanced 
physics,  advanced  biology  and  advanced  mathematics  in  our  high 
schools.  We  created  an  elite  of  advanced  students — and  we  achieved 
positive  results,  plus  some  negative  ones.  How  many  students  whose 
bent  was  in  the  direction  of  humanities  received  advanced  courses  in 
those  fields?  And  how  many  of  these  same  students  were  instructed  in 
basic  science  using  examples  relevant  to  their  future  role  as  adult 
decision-makers  in  an  age  where  progress  in  technology  is  common 
place — but  dependent  on  the  progress  in  science  ? 

We  put  our  best  teachers  into  major  courses  in  institutions  of 
higher  learning  and  neglected  the  courses  for  liberal  arts  and  business 
students;  and  we  achieved  positive  results,  plus  some  negative  ones. 
How  many  students  joined  C.  P.  Snow's  "other  culture"  with  no  under- 
standing  of   science   and   even   a   complete   disdain   for  it? 

I  submit  that  for  the  past  two  decades  we  have  communicated  in 
science  education  to  a  very  select  group.  The  total  number  of  this  group, 
although  in  our  eyes  large,  simply  does  not  represent  the  critical  mass, 
in  our  population,  under  our  system  of  government,  necessary  to  insure 
support  of  science  at  a  sound  fiscal  level.  Sound  in  terms  of  the  total 
national  prosperity  and  sound  in  terms  of  permitting  the  type  of  planned 
organization    and    growth   which   characterizes    science   itself. 

In  20  years  then,  characterized  by  unprecedented  emphasis  in 
science  education,  we  have  produced  one  generation  and  begun  another 
who  possess  a  very  basic  misunderstanding  of  what  science  is  and  what 
it  can  do.  The  youth  of  this  age — and  here  I  speak  of  our  current  high 
school  and  college  populations — are  convinced  that  science  does  not  have 
all  the  answers.  I  believe  this  is  youthful  wisdom.  Not  all  of  our 
problems — certainly  not  all  of  the  socio-economic  behavioral  complex  of 
urbanization — are  susceptible  to  resolution  by  application  of  science.  But 
I  fear  this  glimpse  of  wisdom  carries  with  it  youthful  immaturity. 
Immaturity  that  will  lead — should  I  say  is  leading? — to  the  abandon- 
ment of  science.  How  else  do  you  explain  the  national  trend  of  de- 
creased enrollments  in  science  ? 


Address  69 

I  call  then  for  a  very  serious  reconsideration  of  our  entire  approach 
to  science  communication  in  terms  of  basic  education.  I  do  not  seek  to 
materially  reduce  the  concentration  on  a  selected  few,  but  I  ask  for 
balance  and  certainly  more  attention  to  the  education  of  the  non- 
scientist,  particularly  to  his  understanding  of  science  and  technology. 
This  understanding  should  be  developed  in  terms  relevant  to  his  role 
as  an  adult  in  an  age  where  science  can  and  does  permeate  every  aspect 
of  life. 

The  second  point  of  communication  with  the  non-scientist  is  with 
the  adult  and  I  suggest  this  as  a  function  of  this  academy,  its  sister 
institutions   and   other   organized   elements   in   science. 

Our  aims  on  a  long  term  basis  would  be  to  reinforce  public  under- 
standing for  the  sake  of  science  and  its  support  and  to  provide  a 
continual  updating  of  scientific  background  as  a  basis  for  decision 
making  in  public  policy  and  personal  problems. 

In  an  address  to  the  1966  Academy  Conference  of  the  AAAS,  E. 
G.  Sherburne,  Jr.,  Director  of  Science  Service,  outlined  a  program  for 
the  academies — a  program  of  communication  to  the  non-scientist.  I 
endorse  his  proposal  as  timely  and  efficient.  Sherburne  noted  that  two- 
tenths  of  one  percent  of  the  population  in  any  state  or  city  are  the 
leaders.  For  them  he  suggested: 

1.  that  the  Academy  establish  a  science  advisor  to  the  governor 
and  an  advisory  committee  in  frank  imitation  to  the  presidential 
science  advisor  and  his  committee. 

2.  that  the  Academy  conduct  science  seminars  on  relevant  problems 
for  members  of  the  state  legislature  or  even  county  boards. 

3.  that  the  Academy  appoint  ad  hoc  committees  to  study  problems 
relevant  to  science  at  the  state  level  and  to  communicate  the 
findings   and   recommendations   to  the   decision  makers. 

Through  its  committee  on  Science  and  Society,  the  Academy  has  moved 
to  implement  some  of  these  ideas.  The  Committee's  activity  should  be 
strongly  endorsed  by  effort  on  the  part  of  each  member  to  implement 
the  program. 

At  the  same  Academy  Conference,  I  addressed  the  representatives 
on  the  role  of  academies  of  science  in  the  field  of  scientific  publications. 
In  my  talk  I  reviewed  the  publication  practices  of  some  48  academies  of 
science.  Only  2  of  the  48  publish  newsletters  directed  solely  to  the 
general  public.  Yet  these  two  by  their  action  recognize  an  important 
role  of  the  scientist  and  his  organizations — namely  the  communication 
to  the  attentive  public  of  studied  opinions  on  those  matters  affecting 
science,  and  those  problems  facing  the  state  for  which  there  is  an 
answer  in  science. 

In  conclusion,  may  I  point  out  that  regardless  of  your  role  as  a 
scientist,  you  have  a  stake  in  development  of  a  critical  mass.  For 
each  of  you  in  your  day  to  day  activities  are  communicators  of  science. 
Your  decisions  in  communicating  science  produce  both  positive  and  nega- 
tive effects.  Science,  today,  cannot  afford  negativism.  If  you  agree  with 
me,  will  you  begin  today  to  meet  the  challenge?

Stratigraphy  of  the  White  Site.  Ronald  L.  Michael,  Ball  State  Univer-

1968  at  Mound  3,  Hn-10  (IAS-BSU),  located  on  the  near  southwest  side 
of  New  Castle,  Indiana.  The  work  consisted  primarily  of  searching  for 
the  base  of  the  mound.  The  perimeter  of  the  central  section  of  the 
mound  was  trenched  around  using  5x5  excavation  units.  After  each 
trench  was  excavated  to  a  depth  of  about  two  feet  below  the  mound 
base,  soil  profiles  were  taken  of  each  trench.  On  the  basis  of  the  soil 
profiles  and  artifacts  recovered,  which  included  copper  bracelets,  pottery 
and  ground  stone  chunkey  stones,  bifacially  flaked  chert  points,  and  a 
unifacially  flaked  chert  scraper,  the  mound  was  concluded  to  be  middle 
or  late  Adena.

assemblage  of  artifacts  recovered  from  the  surface  and  during  excava- 
tion, plus  an  extensive,  multiple  post  hole  pattern,  suggests  a  Late

thought  that  the  area  between  the  two  lobes  of  the  mound  was  filled  by 
erosion.  However,  three  secondary  cremation  burials  were  found  in  this 
area.  A  large  sheet  of  mica  and  a  copper  band  of  questionable  use  was 
found  in  association  with  one  of  the  burials.

non-Indians.  Based  on  research  conducted  between  1958  and  1962,  I 
characterized  this  community  as  a  strongly  conservative  one.  I  offered 
an  analysis  which  suggested  that  the  peculiar  residence  patterns  followed 
by  the  Indians  operated  in  ways  which  made  these  conservative  tendencies 
most  notable  in  those  areas  of  community  life  which  were  controlled 
by  men. 

In  the  last  six  years,  San  Bartolome's  Indians  have  undergone  a 
series  of  drastic  shifts  in  cultural  orientations.  These  have  been  strong- 
est in  political  and  economic  affairs,  particularly  in  those  areas  which 
involve  contact  and  interaction  with  the  non-Indian  world  at  the  levels 
of  town,  state,  and  nation.  It  is  remarkable  that  these  changes  have 
been  most  far-reaching  precisely  in  those  activities  which  are  primarily 
controlled  by  men.  This  paper  outlines  the  major  areas  of  recent  change, 
and  seeks  an  explanation  of  those  changes  in  a  basic  shift  in  the 
cultural  ecology  of  the  surrounding  region.

The  Incidence  of  the  Perforation  of  the  Coronoid-olecranon 

Septum  in  the  Middle  Mississippian  Population  of 

Dickson  Mounds,  Fulton  County,  Illinois

Abstract 

The  humeral  septum  is  a  thin  plate  of  bone  between  the  coronoid  and 
olecranon  fossae  at  the  distal  end  of  the  humerus.  Into  these  fossae  fit  the 
coronoid  and  olecranon  processes  of  the  ulna  and  together  they  form  the 
hinge  joint  of  the  elbow.  Occasionally  the  septum  dividing  the  fossae  is 
perforated. 

During  the  summer  of  19G8  the  authors  conducted  a  quantitative  and 
qualitative  study  of  the  perforation  of  the  coronoid-olecranon  septum 
in  a  prehistoric  Middle  Mississippian  American  Indian  population  at 
Dickson  Mounds,  Fulton  County,  Illinois.  Included  in  the  study  were 
determination  of  the  incidence  of  bilateral  and  unilateral  perforation,  the 
relationship  of  the  perforation  with  age  and  sex,  and  the  possible  relation- 
ship   of    the    size    of    the    perforation    with    age    and    sex. 

It  was  found  that  the  perforation  of  the  coronoid-olecranon  septum  is 
positively  correlated  with  sex,  occurring  more  commonly  in  females.  The 
perforation  seems  to  be  absent  in  infants  and  children.  The  size  of  the 
perforation    does    not    seem    to    increase    with    age. 

Introduction 

At  the  distal  end  of  the  humerus  is  a  thin  plate  of  compact  bone 
which  separates  the  coronoid  fossa  and  the  olecranon  fossa.  The  bone 
between  the  two  fossae  is  termed  the  humeral,  or  coronoid-olecranon, 
septum.  Into  these  fossae  fit  the  coronoid  and  olecranon  processes, 
respectively,  of  the  ulna.  These  hook-like  processes  of  the  ulna  together 
with  the  rounded  trochlea  and  fossae  of  the  humerus  form  the  hinge 
joint  of  the  elbow.  Extension  of  the  arm  is  limited  by  contact  between 
the  olecranon  process  and  posterior  surface  of  the  septum.  Flexion  at  the 
elbow  is  restricted  by  contact  between  the  coronoid  process  and  the 
anterior  surface  of  the  septum  and  the  intervening  soft  tissue  on  the 
anterior  aspect  of  the  upper  and  lower  arm. 

Occasionally  the  coronoid-olecranon  septum  is  perforated  (Figure  1). 
Apertures  in  the  septum  may  be  bilateral,  that  is,  occurring  in  both 
humeri  of  one  individual,  or  it  may  be  unilateral,  occurring  on  either 
the  right  or  left  side.  Hrdlicka  noted  the  occurrence  of  bilaterally  and 
unilaterally  perforated  septa  in  a  variety  of  mammalian  species,  thus 
demonstrating  that  the  presence  of  the  aperture  is  not  species-specific 
(6).  Among  human  populations  the  frequency  of  the  perforation  varies 
from  close  to  zero  to  almost  60%  (1).  In  most  human  groups  observed 
to  date,  perforated  septa  are  more  common  among  females  than  males, 
and  when  present  are  predominantly  bilateral.  The  incidence  of 
perforated  septa  is  greater  in  the  left  than  right  humerus. 

Various  theories  have  been  put  forth  to  explain  the  causes  of  the 
variability   within   and   between   human   populations.    Both    genetic    and 

73

environmental  determinants  have  been  invoked,  but  it  remains  unclear 
as  to  what  degree  the  various  factors  contribute  to  the  formation  of  the 
aperture.  The  mechanical  hypothesis  contends  that  the  perforation  is  a 
result  of  activity  which  wears  a  hole  in  the  septum.  The  aperture  may 
be  formed  by  certain  types  of  activity  or  activities  of  long  duration  and 
thus  might  be  culturally  determined. 


Figure  1.  Anterior  view  of  two 
right  humeri.  The  coronoid-ole- 
cranon  septum  of  the  humerus  on 
the  left  is  unperforated  while  the 
septum  of  the  humerus  on  the  right 
is    perforated. 


In  a  qualitative  study  conducted  in  1932,  Hrdlicka  posited  a  phylo- 
genetic  origin  for  perforation  of  the  coronoid-olecranon  septum,  sug- 
gesting that  the  potential  for  the  perforation  is  inherited  as  one  of  a 
number  of  generalized  mammalian  traits  (6).  As  evidence,  he  cites 
comparative  data  which  demonstrates  similar  frequencies  of  incidence 
and  comparable  sexual  variability  in  a  variety  of  infrahuman  mammals. 
Hrdlicka  also  pointed  out  that  the  differences  in  the  frequency  of  the 
perforation  among  human  populations  sharing  similar  physique  and 
mode  of  life  and  activity  suggest  that  presence  of  the  aperture  is 
common  to  all  human  groups.  Hrdlicka  further  suggests  that  the  reali- 
zation of  this  genetic  potential  is  determined  by  the  degree  of  robusticity 
of  the  humerus.  The  greater  the  muscularity  of  an  individual,  the 
greater  the  bone  formation  and  consequently  the  less  likely  that  incom- 
plete ossification  will  result  in  the  absence  of  bone  at  the  septum.  Thus 
lack  of  bone  resorption  may  result  in  the  perforated  coronoid-olecranon 
septum.  This  theory  would  explain  the  higher  incidence  of  the  perfora- 
tion on  the  weaker  left  arm  of  right-handed  individuals,  and  the  greater 


Anthropology  75 

frequency   of   the   perforation   among   females   who    are    generally   less 
robust  than  males. 

Recent  studies  have  tended  to  ignore  Hrdlicka's  phylogenetic  theory 
and  have  concentrated  on  the  interpretation  that  the  degree  of  robusticity 
is  fundamental  in  determining  the  presence  or  absence  of  the  perfora- 
tion. Benfer  and  McKem  found  a  positive  correlation  between  the  size 
of  the  humerus  and  the  presence  of  perforation  of  the  humeral  septum 
(1).  Using  minimum  middle  diameter  of  the  humerus  as  a  quantitative 
assessment  of  robusticity,  the  authors  noted  that  the  aperture  was  more 
likely  to  be  present  in  humeri  of  smaller  diameter.  Glanville,  in  1967, 
published  evidence  suggesting  a  positive  correlation  between  the  pres- 
ence of  the  perforation  and  longer  coronoid  and  olecranon  processes  and 
increased  angles  of  flexion  and  extension  (5).  If  robusticity  is  positively 
correlated  with  the  length  of  the  ulnar  processes,  then  Glanville's  find- 
ings lend  support  to  the  robusticity  theory. 

Sample 

During  the  summer  of  1968,  while  analyzing  the  skeletal  material 
excavated  at  Dickson  Mounds,  the  authors  conducted  a  qualitative  and 
quantitative  study  of  the  performation  of  the  coronoid-olecranon  septum. 
Dickson  Mounds  (F°34)  is  one  of  over  fourteen  hundred  prehistoric 
American  Indian  sites  in  Fulton  County,  Illinois.  The  semilunar-shaped 
mound  is  located  on  a  bluff  overlooking  the  west  floodplain  of  the  Illinois 
River  approximately  thirty-five  miles  southwest  of  the  present  Peoria, 
Illinois.  The  artifact  assemblage  associated  with  the  burials  indicates 
that  the  site  was  used  as  a  burial  cemetery  by  a  Middle  Mississippian 
population  (4),  although  recent  evidence  suggests  that  a  few  of  the 
burials  represent  a  Late  Woodland  people  (3).  Radiocarbon  dates  for 
the  Eveland  site,  a  Middle  Mississippian  site  adjacent  to  Dickson 
Mounds,  range  from  950  to  1350  A.D.  (communication  from  E.  J. 
Blasingham). 

To  date,  the  number  of  burials  recovered  at  Dickson  Mounds  ap- 
proximates 1050.  The  majority  of  the  burials  are  in  an  excellent  state  of 
preservation  due  to  the  alkalinity  of  the  loess  deposits  of  which  the 
mound  is  constructed.  The  sample  includes  those  burials  removed  during 
the  1966,  1967,  and  1968  summer  excavations  as  well  as  those  left  ex- 
posed in  situ  in  the  enclosed  museum  for  display  purposes. 

In  the  present  study  of  the  perforation  of  the  humeral  septum  the 
authors  examined  only  those  skeletons  for  which  age  and  sex  had  been 
previously  determined  (2).  In  addition,  all  Late  Woodland  burials  were 
omitted  from  the  analysis  because  it  was  felt  that  to  include  them  in 
the  study  might  invalidate  the  findings.  The  Late  Woodland  people 
may  have  been  subjected  to  different  cultural  and  physical  factors  than 
the  Middle  Mississippian  population,  and  these  factors  may  have  con- 
tributed to  the  formation  of  the  perforation  as  the  mechanical  theory 
suggests. 

The  sample  size  was  further  reduced  by  selecting  out  for  analysis 
only  those  burials  for  which  at  least  the  distal  portion  of  both  humeri 


76  Indiana  Academy  of  Science 

were  available.  The  purpose  in  doing  so  was  to  eliminate  sampling  error 
which  would  skew  the  relative  percentages  of  the  incidence  of  perfora- 
tion among  males  and  females  and  the  frequencies  of  right,  left,  and 
bilaterally  perforated  septa.  As  a  result,  the  sample  was  pared  down 
to  147  burials  of  which  thirty-two  were  infants  and  children  of  indetermi- 
nant  sex.  These  burials  were  excluded  from  the  analysis  so  that 
an  accurate  sex  ratio  could  be  ascertained.  Therefore  115  burials  were 
utilized  in  the  study. 

Methods 

Perforation  of  the  coronoid-olecranon  septum  has  usually  been 
treated  as  a  qualitative  trait,  whose  presence  or  absence  has  been  cor- 
related with  various  properties  of  the  humerus.  The  present  study  is 
both  qualitative  and  quantitative  in  the  sense  that,  in  addition  to 
observation  of  the  occurrence  and  nonoccurence  of  the  perforation, 
osteometric  measurements  of  the  aperture  were  taken. 

First  each  individual  was  examined  for  presence  or  absence  of  the 
perforation.  Bilateral  and  unilateral  perforations  were  noted.  The  fre- 
quency of  unperforated  septa  and  bilaterally  and  unilaterally  right  and 
left  perforated  septa  were  then  separated  out  according  to  sex  and 
graphed  in  Figure  2  to  illustrate  the  sex  differential.  From  these  fre- 
quencies it  was  possible  to  derive  percentages  which  demonstrate  the 
incidence  of  the  perforation  in  relation  to  the  total  sample  (N)  and 
male    (Ni)    and    female    (N2)    samples    (Fig.    3).    The    chi-square    test, 

e 

was  applied  to  determine  the  significance  of  the  following  variations:  1) 
distribution  of  the  perforation  by  sex,  2)  distribution  of  bilateral  perfora- 
tion by  sex,  3)  distribution  of  unilateral  right  perforation  by  sex,  and 
4) distribution  of  unilateral  left  perforation  by  sex.  Chi-square  values 
and  significance,  or  level  of  confidence,  (p)  are  given  in  Figure  3.  In 
all  cases  the  0.05  level  of  significance  was  required. 

All  perforations  were  then  measured.  (In  four  incidences,  post- 
mortem damage  rendered  the  aperture  immeasurable.)  The  width  and 
height  of  the  perforation  were  measured  on  the  anterior  aspect  of  the 
bone  using  sliding  calipers  accurate  to  0.1  mm.  Width  was  taken  as  the 
maximum  distance  across  the  aperture  on  a  line  perpendicular  to  the 
central  axis  of  the  shaft,  or  diaphysis,  of  the  humerus.  The  height  was 
taken  as  the  maximum  distance  across  the  aperture  on  a  line  parallel 
to  the  central  axis  of  the  diaphysis  of  the  humerus.  As  a  measure  of 
the  relative  size  of  the  perforation  the  two  dimensions  were  summed. 
The  purpose  of  this  quantitative  procedure  was  to  provide  data  which 
might  indicate  sex  and  age  variations  in  the  size  of  the  perforation.  To 
this  end,  the  mean  (X)  values  of  the  width  and  height  of  the  perfora- 
tions of  both  the  right  and  left  humerus  were  derived  for  males  and 
females  independently  (Fig.  4).  To  indicate  the  individual  variability  in 
size,  standard  deviation,

Not  shown  is  a  table  in  which  the  size  of  the  perforation  is  plotted 
against  the  age  gradient  of  the  total  sample  of  individuals  with  apertures 
(n— 45),  males  displaying  perforation  (n=17)  and  females  displaying 
perforation  (n=28).  The  results  are  discussed  below. 

Results 

Of  the  115  individuals  represented  in  the  sample,  forty-five,  or 
39.1%,  possessed  either  bilateral  or  unilateral  perforations  of  the  coro- 
noid-olecranon  septum.  Although  the  sample  includes  more  males  than 
females  (59:56),  apertures  occur  more  frequently  in  females,  twenty- 
eight  to  seventeen  (Fig.  2).  Perhaps  more  revealing  is  the  fact  that 
50.0%  of  the  female  population  manifests  bilateral  or  unilateral  perfora- 
tions, whereas  occurrence  is  limited  to  28.8%  among  males.  The  chi- 
square  test  was  applied  to  determine  the  significance  of  the  differential 
incidence  by  sex,  and  although  it  proved  insignificant  at  the  0.05  level 
of  confidence  (Fig.  3),  the  disparity  should  not  be  overlooked. 

Of  the  115  burials,  26.1%  represent  individuals  with  bilateral  per- 
forations. In  both  sexes  bilaterally  perforated  septa  were  more  common 
than  unilateral  perforations,  occurring  in  thirty  of  the  forty-five  cases 
in  which  perforations  were  observed.  However,  bilateral  perforation  of 
the  humeral  septum  is  present  in  37.5%,  represented  by  twenty-one 
individuals,  of  the  female  sample  (Ns),  while  it  occurs  in  only  15.3% 
(nine  burials)  in  the  male  population  (Ni).  The  difference  proved  to  be 
significant  at  the  0.05  level,  p  equalling  0.03  (Fig.  3). 

It  is  of  interest  to  note  that  the  findings  are  consistent  with  the 
data  presented  in  previous  studies  and  lends  strong  support  to  the 
robusticity  theory.  The  fact  that  the  aperture  is  more  common  among 
females  suggest  that  the  lack  of  robusticity  observed  in  females  is 
positively  correlated  with  presence  of  the  aperture. 

Unilaterally  perforated  septa  were  few,  occurring  in  13.0%  of  the 
total  sample.  Of  the  fifteen  unilateral  perforations,  ten  were  noted  on 
the  left  humerus.  There  is  little  sexual  variation;  both  males  and  females 
manifesting  five  apertures  on  the  left  humerus  and  three  and  two  per- 
forated septa,  respectively,  on  the  right  humerus.  The  2:1  ratio  observed 
between  left  and  right  septa  may  reflect  a  lack  of  robusticity  of  the 
left  humerus  in  right-handed  individuals;  however  this  conclusion  is 
questionable  since  the  sample  size  is  small  and  whether  this  population 
was  indeed  predominantly  right-handed  remains  unknown.  The  fact  that 
there  are  twice  as  many  bilateral  perforations  as  unilaterial  perforations 
probably  indicates  that  the  differences  in  robusticity  between  individuals 
is  far  greater  than  that  between  the  two  humeri  of  the  same  individual. 

When  all  burials  were  listed  in  order  of  ascending  age  at  the  time 
of  death,  it  was  noted  that  the  width  and  height  of  the  aperture  of 
both  the  left  and  right  humerus  did  not  increase  with  age.  If  the  per- 
foration is  related  to  activity  as  suggested  by  the  mechanical  theory, 
one  might  expect  the  aperture  to  enlarge  with  age,  at  least  until  the

third  decade  when  a  decline  in  activity  is  inevitable.  The  data  suggests 
that  the  duration  of  the  activity  is  not  involved  in  the  formation  or 
development  of  the  perforation.  It  should,  however,  be  noted  that  only 
the  size  of  the  perforation  at  the  time  of  death  is  known  and  not  what 
the  size  might  have  been  five,  ten,  or  twenty  years  before  death.  The 


Anthropology  81 

assumption   has   thus   been  made   that   the   age   gradient  for  the   entire 
population  is  an  accurate  reflection  of  the  size  at  different  ages. 

The  age  of  the  onset  of  the  performance  seems  to  be  during  the 
second  decade  when  development  of  musculature  is  at  a  maximum  and 
bone  formation  is  approaching  completion.  Of  the  thirty-four  individuals 
observed  under  age  twelve  years,  only  two  evidenced  perforation  of 
either  humerus.  The  two  exceptions,  seven  and  eight  year  old  females, 
possessed  large  perforations  which  may  reflect  early  maturation  or 
genetic  variability. 

The  mean  dimension  of  the  width  and  height  of  perforations  of 
both  the  right  and  left  humerus  are,  in  each  case,  larger  in  females  than 
males  (Fig.  4).  When  the  chi-square  test  is  employed  to  determine  the 
significance  of  the  defference  in  size  between  males  and  females,  it  is 
observed  that  the  disparity  is  significant  to  the  0.05  level  of  confidence. 
This  quantitative  finding,  coupled  with  the  greater  incidence  of  per- 
forations among  females,  lends  credence  to  the  robusticity  theory.  It 
should  also  be  noted  that  the  mean  width  and  height  of  the  aperture  of 
the  left  humerus  is  greater  than  that  of  the  right  (Fig.  4).  This  fact, 
too,  supports  the  robusticity  theory. 

Conclusions 

In  summary,  on  the  basis  of  the  present  study  of  the  perforation  of 
the  coronoid-olecranon  septum,  the  following  conclusions  can  be  stated: 

1)  The  incidence  of  perforation  is  greater  in  females  than  males. 

2)  The  incidence  of  bilaterally  perforated  septa  is  significantly  greater 
among  females. 

3)  The  size  of  the  perforation  in  both  humeri  is  significantly  larger  in 
females. 

4)  Bilateral  perforations  are  twice  as  common  as  unilaterial  perfora- 
tions. 

5)  Perforations  of  the  left  humerus  occur  twice  as  often  as  perfora- 
tions of  the  right  humerus. 

6)  The  size  of  the  aperture   of  the  left  humerus  is  uniformly  larger 
than  the  left. 

7)  The  size  of  the  perforation  does  not  increase  with  age. 

The  current  study  provides  data  which  may  refute  the  mechanical 
theory.  If  the  perforation  is  indeed  produced  by  wear,  one  would  expect 
the  size  of  the  perforation  to  increase  with  the  accumulating  duration 
of  activity.  Because  the  size  of  the  perforation  of  the  humeral  septum 
does  not  increase  with  age,  the  authors  reject  the  mechanical  theory  as 
untenable  in  light  of  the  present  findings. 

Both  the  qualitative  and  quantitative  data  collected  during  the 
study  lend  support  to  the  robusticity  theory.  The  authors  accept 
Hrdlicka's  contention  that  the  presence  of  the  perforation  is  positively 
correlated  with  the  lack  of  robusticity  due  to  incomplete  bone  formation

of  the  humeral  septum  (6).  As  evidence  it  is  possible  to  cite  the  greater 
incidence  of  perforation  (and  bilateral  perforations)  among  females  who 
are  less  robust  than  males.  Quantitatively,  the  mean  dimensions  of  both 
humeri  are  absolutely  larger  in  females  than  males,  suggesting  a  lesser 
degree  of  bone  resorption  among  females.  The  greater  frequency  and 
larger  size  of  the  perforation  of  the  left  humerus  also  tend  to  substanti- 
ate the  robusticity  theory,  if  indeed  the  majority  of  the  sample  was 
right-handed. 

The  authors  have  no  basis  for  either  accepting  or  refuting  Hrdlicka's 
proposed  phylogenetic  origin  of  the  perforation  of  the  coronoid- 
olecranon  septum.  However,  it  is  suggested  that  perhaps  it  is  not  the 
potential  for  the  perforation  that  is  inherited,  but  rather  that  the  poten- 
tial for  degrees  of  robusticity  are  inherited  and  conditioned  by  environ- 
mental factors,  the  result  of  which  is  the  presence  or  absence  of  the 
humeral    septum. 

It  seems  probable  that  the  perforation  of  the  coronoid-olecranon 
septum  is  a  result  of  more  than  one  or  two  interrelated  factors.  Before 
it  is  possible  to  understand  this  complex  problem,  more  data  will  be 
required.  More  extensive  studies  as  well  as  more  intensive  analyses  of 
existing  data  are  necessary  before  the  questions  touched  upon  here  can 
be  fully  answered.

The  Linear  Growth  of  Long  Bones  in 
Late  Woodland  Indian  Children 

Phillip  L.  Walker,  Indiana  University 

Abstract 

Studies  of  the  linear  growth  of  long  bones  in  children  have  almost 
exclusively  utilized  indirect  measurements  of  the  living  plotted  against 
chronological  age.  Such  studies  are  only  in  a  very  general  way  applicable 
to  age  determination  in  archaeological  populations.  The  present  study  is 
based  on  direct  measurements  of  Late  Woodland  Indian  Children  and  phys- 
iological age  based  on  the  degree  of  the  development  of  the  dentition.  By 
plotting  the  lengths  of  individual  long  bones  against  dental  age,  group 
growth  curves  were  constructed  which  allow  the  investigator  to  determine 
the  dental  age  of  an  individual  when  adequate  dentition  is  not  present  by 
measurement  of  the  long  bone  alone.  To  discern  the  applicability  of  growth 
curves  for  a  specific  prehistoric  American  Indian  population  to  other  similar 
populations  a  comparative  study  of  a  Middle  Mississippian  group  was  under- 
taken. Although  the  results  of  this  comparison  were  inconclusive,  it  seems 
prudent  to  apply  the  growth  curves  for  the  Late  Woodland  population 
studied  only  to  very  similar  populations  until  more  extensive  comparisons 
can  be  made. 

Studies  of  the  linear  growth  of  long  bones  in  children  have  almost 
exclusively  been  limited  to  indirect  measurements  of  the  living  taken 
from  radiographs.  Such  studies  introduce  elements  of  distortion  because 
of  individual  variability  of  the  soft  tissues  and  cannot  be  considered  as 
parallel  to  direct  measurements  of  dried  bones  (2).  Usually  the  ages 
recorded  for  children  in  such  studies  are  chronological  rather  than  physio- 
logical. That  is,  they  reflect  the  number  of  years  since  birth  and  not 
physiological  maturity.  In  populations  obtained  from  archaeological 
excavations  only  direct  measurements  of  long  bones  can  be  made.  It  is 
also  obvious  that  only  the  physiological  age  of  the  individual  as  indicated 
by  dental  and  skeletal  maturity  can  be  obtained.  Because  of  these  dis- 
crepancies, age  growth  curves  based  on  indirect  measurements  of  the 
living  are  only  in  a  very  general  way  applicable  to  age  determination 
from  direct  measurements  of  the  skeletal  remains  of  archaeological 
populations. 

To  avoid  the  error  of  applying  growth  curves  based  on  indirect 
measurement  and  chronological  age  to  skeletal  populations,  it  seems 
reasonable  to  construct  a  group  growth  curve  based  on  direct  measure- 
ment of  long  bones  and  physiological  age  based  on  the  degree  of  devel- 
opment of  the  teeth.  Group  growth  studies  of  this  type  have  previously 
been  done  by  King  B.  Hunter  for  the  Hopewellian  population  of  the 
Klunk  mound  group  in  Calhoun  County,  Illinois.  The  present  study 
follows  Hunter's  basic  procedures. 

The  use  of  dental  development  as  an  age  determinant  is  based  on  sev- 
eral factors.  Teeth  are  consistently  well  preserved  in  archaeological  pop- 
ulations and  offer  a  rather  complete  record  of  growth.  Secondly,  the 
rate  of  development  of  the  dentition  is  much  less  subject  to  variation 
due    to    extraneous    environmental   factors    than    is    long    bone    growth.

Under  conditions  of  dietary  and  hormonal  stress  the  teeth  seem  to 
have  priority  for  the  use  of  deficient  materials  (1).  For  this  reason 
teeth  develop  at  a  rather  constant  rate  even  in  diverse  populations.  This 
is  in  sharp  contrast  to  the  rate  of  growth  of  long  bones  which  varies 
significantly  between  populations.  These  growth  factors  allow  the  appli- 
cation of  standard  chronologies  for  tooth  development  to  archaeological 
populations  of  unknown  nutritional  and  physical  makeup  with  a  high 
degree  of  accuracy.  In  growth  studies  of  skeletal  populations  therefore, 
the  dental  age  of  the  individual  can  be  treated  as  a  relative  constant 
against  which  the  much  greater  variability  of  long  bone  growth  can  be 
plotted. 

Charts  which  plot  dental  age  against  long  bone  length  of  a  popula- 
tion are  of  great  value  because  they  allow  the  investigator  to  determine 
the  approximate  dental  age  of  a  child  by  direct  measurement  of  long 
bones  alone.  Such  charts  are  of  particular  value  when  dealing  with  an 
archaeological  population  because  demographic  studies  can  be  made 
which  include  individuals  who  do  not  have  adequate  dentition  for  the 
assessment  of  dental  age  but  do  have  intact  long  bones.  Because  of  the 
increased  sample  size  obtained  from  such  assessments  the  validity  of 
conclusions  based  on  resultant  mortality  statistics  is  increased. 

The  skeletal  material  used  in  the  present  study  was  excavated  by 
Gregory  Perino  during  the  summers  of  1967  and  1968  from  the  Yokem 
mound  group  in  Pike  County,  Illinois.  The  Yokem  mound  group  consists 
of  ten  mounds  which  represent  two  distinct  occupations  of  the  area.  Five 
of  the  mounds  contained  a  bluff  culture  artifact  assemblage  and  represent 
a  relatively  early  Late  Woodland  occupation  of  the  area.  The  remaining 
mounds  represent  a  late  occupation  of  the  area  by  another  group  of 
Late  Woodland  peoples.  Burial  practices  and  artifacts  from  these  later 
mounds  indicate  that  this  group  was  assimilating  Middle  Mississippian 
patterns.  This  assumption  is  corroborated  by  a  relatively  late 
radiocarbon   date    of   A.D.   1208 ±  90   years. 

The  date  for  this  study  was  obtained  from  children  of  the  later 
population  of  Late  Woodland  peoples  to  use  the  Yokem  mounds.  These 
were  individuals  excavated  from  mounds  ll-Pk°167,  ll-Pk°168, 
ll-Pk°169,  ll-Pk°170,  and  ll-Pk°171.  Forty-three  children  were  examined 
ranging  in  age  from  zero  months  to  12  years.  Twenty-three  additional 
children  were  excluded  from  the  sample,  either  because  adequate  denti- 
tion and  measurable  long  bones  were  missing  or  because  marked  dental 
pathologies  were  present  wiiich  would  obscure   developmental  patterns. 

The  dental  age  for  each  individual  was  assessed  in  terms  of  five 
stages  of  dental  development.  These  stages  are:  first  evidence  of  calci- 
fication, crown  completion,  eruption,  root  completion,  and  root  reabsorp- 
tion.   All  measurements  of  long  bones  were  made  exclusive  of  epiphyses. 

Figures  1,  2,  and  3  represent  the  relationship  between  the  long  bone 
lengths  and  the  dental  ages  of  the  Late  Woodland  population  of  the

sent  the  smoothed  curve  formed  by  these  values.  When  these  curves  are 
examined  it  will  be  noted  that  at  the  age  of  about  two  and  one-half  years 
the  rate  of  growth  consistently  decreases  for  all  long  bones.  This 
decrease  in  rate  of  growth  represents  the  end  of  the  rapid  growth  of 
infancy.  The  next  marked  change  in  the  growth  rate  takes  place  at  about 
nine  years  of  age  where  growth  accelerates.  This  change  in  rate  repre- 
sents the  hormonal  initiation  of  growth  in  females  of  the  population.  It 
should  be  mentioned  that  no  sexual  identification  was  attempted  for  the 
children  used  in  this  study  for  two  reasons.  First  the  number  of  indi- 
viduals of  the  ages  during  which  differential  growth  rates  because  of 
sexual  differentiation  is  too  small  to  produce  a  valid  sexual  separation. 
Second,  sexual  identification  of  the  skeletal  remains  of  children  is  often 
unreliable,  particularly  when  the  ilium  is  not  present  to  permit  the 
measurement  of  the  greater  sciatic  notch.  Because  sexual  identification 
was  not  made,  the  female  growth  spurt  which  occurs  at  about  nine  years 
will  be  partially  obscured  by  the  unchanging  male  growth  rate.  At  this 
point  it  should  be  emphasized  that  the  growth  curves  illustrated  in 
Figures  1,  2,  and  3  do  not  indicate  the  growth  rate  of  the  average  or 
normal  individual,  but  illustrate  the  growth  of  the  population  as  a  group 
(2),  regardless   of  sex. 

To  show  the  degree  to  which  the  growth  charts  constructed  for  the 
Yokem  mound  Late  Woodland  population  can  be  applied  to  other  prehis- 
toric American  Indian  populations,  a  Middle  Mississippian  population 
was  examined  and  data  comparable  to  that  from  Yokem  mounds  was 
obtained.  The  individuals  used  in  this  comparative  study  were  taken 
from  burials  excavated  at  Dickson  Mounds  (ll-F°-34)  in  Fulton  County, 
Illinois,  during  the  summers  of  1966  and  1967.  This  sample  excluded  the 
Late  Woodland  component  of  this  site.  Figure  4  represents  by  dots  the 
dental  age  plotted  against  the  ulna  length  of  14  children  from  Dickson 
Mound.  There  is  no  significant  deviation  in  the  growth  rates  of  the  two 
populations  during  early  childhood.  In  later  years,  especially  during  the 
period  of  adolescent  growth  acceleration  in  females,  the  comparative 
sample  shows  consistently  larger  long  bone  lengths.  There  are  several 
possible  explanations  for  this  deviation.  Because  of  the  small  size  of 
the  comparative  sample,  sampling  errors  could  easily  account  for  this 
deviation.  An  alternative  explanation  could  be  that  the  two  populations 
were  nutritionally  and/or  physically  different,  and  it  is  these  differences 
that  are  reflected  in  Figure  4.  Until  larger  comparative  studies  can  be 
done,  the  growth  rates  of  the  Late  Woodland  population  which  is  the 
subject  of  this  study  should  be  considered  as  strictly  applicable  only  to 
populations  which  are  archaeologically  and  physically  very  similar  to  the 
Yokem   Mound   population.

On  the  Origin  of  the  Tntelo — An  Eastern  Sionan  Tribe 

Ralph  W.  Alexander,  Jr.,  and  Georg  K.  Neumann,  Indiana  University 

Abstract 

This  paper  is  a  contribution  to  the  solution  of  the  puzzling  problem 
posed  by  the  discovery  of  several  Indian  tribes  in  the  Allegheny  Piedmont 
area  who  spoke  languages  related  to  the  Siouan  tribes  of  the  Great  Plains. 
The  discovery  posed  the  question  as  to  whether  the  Siouan  languages 
originated  in  the  East,  the  Plains  area,  or  the  intermediate  area,  the  Obio 
Valley,  that  is,  the  direction  of  their  spread.  By  correlating  linguistic, 
cultural,  and  physical  variables,  the  geographic  and  temporal  relation- 
ships of  these  groupings  are  elucidated.  The  material  that  was  analyzed 
is  the  only  known  sample  representative  of  the  prehistoric  Eastern  Siouan 
population  which  gave  rise  to  the  historic  Tutelo  Indian  tribe  of  North 
Carolina.  The  physical  characteristics  of  this  group  proved  to  be  closely 
related  to  those  of  the  Archaic  series  of  crania  from  Indian  Knoll, 
Kentucky,  a  fact   that  traces  the  Eastern  group   into   the  Ohio  Valley. 

The  Siouan  tribes  of  North  America  may  be  divided  into  two  main 
bodies.  The  larger  Western  group  is  composed  of  such  tribes  as  the 
Quapaw,  Osage,  Kansa,  Missouri,  Oto,  Iowa,  Omaha,  Ponca,  Yankton, 
Santee,  Yanktonai,  Teton,  Mandan,  Hidatsa,  Crow,  Assiniboin,  and 
Winnebago.  The  Eastern  group,  located  in  the  region  of  Virginia,  North 
Carolina  and  South  Carolina,  may  be  divided  into  two  subgroups.  The 
Northern  subgroup  is  typically  represented  by  the  Tutelo,  and  the 
Southern  subgroup  represented  by  the  Catawba.  Although  the  Eastern 
tribes  were  known  to  early  explorers,  they  were  not  recognized  as  having 
a  linguistic  bond  with  the  Western  group  until  1870,  when  Horatio  Hale 
suggested  the  existence  of  a  Siouan  dialect  east  of  the  Appalachians  after 
obtaining  a  vocabulary  from  an  old  Tutelo  man  (4).  Work  by  Hale, 
Gatschet  (3),  and  Dorsey  (2)  was  incorporated  by  James  Mooney  (5) 
into  a  classic  Bureau  of  American  Ethnology  bulletin  which  satisfactorily 
demonstrated  the  Siouan  connection  of  the  Eastern  Groups.  The  estab- 
lishment of  the  widespread  diffusion  of  the  Siouan-speaking  tribes  was 
summarized  by  Paul  Weer  in  1937  in  an  Indiana  History  Bulletin  (8). 
The  Northern,  or  Tutelo  group  of  the  Eastern  Sioux  are  the  most  closely 
related  linguistically  to  the  Western  Sioux.  The  Southern  or  Catawba 
group  is  the  most  aberrant  of  the  Siouan  groups  linguistically.  There 
is  evidence,  as  yet  not  thoroughly  presented,  that  the  Siouan  and 
Muskhogean  linguistic  families  may  be  related,  and  that  the  Catawba 
dialect  may  occupy  an  intermediate  position  between  the  extreme 
branches  of  each.  The  problem,  then,  is  one  of  the  origin  of  the  Eastern 
Sioux,  whose  linguistic  bond  with  the  Western  group  demonstrates  beyond 
a  reasonable  doubt  that  the  two  bodies  had  formerly  been  in  contact. 
We  must  conclude  that  either  the  tribes  occupying  the  territory  between 
had  died  out,  that  the  Eastern  tribes  had  migrated  farther  East  or  the 
Western  farther  West,  or  that  both  easterly  and  westerly  movements  had 
taken  place. 

The  ethnohistoric  evidence  available  supports  the  last  supposition. 
Most  of  the  Western  tribes  retained  until  quite  recently  traditions  of  a

more  easterly  origin.  The  Eastern  tribes,  according  to  historic  docu- 
ments, extended  farther  West.  In  the  Eastern  Piedmont  area,  many 
local  migrations  and  tribal  movements  tend  to  obscure  the  earliest  areas 
of  occupation,  but  the  bulk  of  the  ethnohistoric  evidence  points  to  an 
origin  of  the  Eastern  Siouan  peoples  in  the  Ohio  Valley  area.  Much  of 
the  ethnohistoric  evidence  bearing  on  the  subject  has  been  assembled  by 
John  R.  S wanton   (7). 

Archaeologically,  the  evidence  which  bears  on  the  problem  is  slight, 
but  convincing.  JorTre  Coe,  who  is  the  major  contributor  to  our  archaeo- 
logical knowledge  of  the  Piedmont  area,  considers  the  Badin  Focus  cul- 
ture of  the  Piedmont  to  be  directly  ancestral  to  the  historic  Eastern 
Siouans  (1).  Further,  Coe  feels  that  the  correlation  between  the  Badin 
Focus  culture  and  the  Indian  Knoll  culture  of  Kentucky  is  so  great  that 
some  direct  connection  must  be  postulated.  The  Badin  Focus  culture 
appeared  in  the  Piedmont  at  the  same  time  the  shell-mound  culture  in 
Kentucky  was  replaced  by  the  Adena  people.  On  the  basis  of  trait  com- 
parison, the  Badin-Indian  Knoll  relationship  is  closer  than  any  other  yet 
reported. 

Physical  evidence  bearing  on  the  varietal  affiliations  of  the  Eastern 
Siouan  groups  has,  until  now,  been  almost  totally  lacking.  The  senior 
author  was  the  first  to  postulate  that  the  skeletal  material  from  the 
historic  Tutelo  villages  was  closely  related  to  that  from  the  Archaic 
Indian  Knoll  site,  and  used  the  latter  as  the  type  series,  designated  the 
Iswanid  variety  after  the  Catawba  words  iswa  (river)  and  nie 
(people)    (6). 

The  solution  of  the  problem  of  the  origins  of  the  Eastern  Siouan 
people  is  only  possible  through  the  investigation  of  the  physical  anthro- 
pology of  the  populations  of  the  Eastern  Siouan  area,  comparison  with 
other  established  varieties  of  American  Indians,  and  by  correlation  of 
this  information  with  the  linguistic,  archaeological,  and  ethnohistoric  evi- 
dence available.  This  paper  presents  the  results  of  the  first  bioanthro- 
pological  examination  of  the  only  known  sample  of  Eastern  Siouan  and 
specifically  Tutelo  skeletal  material.  The  sample  used  for  description, 
analysis  and  comparison  consists  of  twenty-eight  adult  crania  from 
Northern  North  Carolina,  excavated  by  JorTre  Coe.  The  original  meas- 
urements and  observations  were  taken  by  G.  K.  Neumann.  The  several 
sites  from  which  the  sample  was  obtained  all  date  from  late  pre-contact 
times,  and  are  directly  ancestral  to  historic  Tutelo  villages.  Since  no 
other  material  is  available,  and  since  the  Tutelo  are  the  most  repre- 
sentative of  the  Northern  dialect  group  of  the  Eastern  Siouans,  the 
sample  will  serve  to  answer  questions  concerned  not  only  with  the 
Tutelo,  but  will  allow  inference  in  regard  to  the  entire  Eastern  Siouan 
population.   No  Catawba  skeletal  material  exists. 

Three  types  of  comparisons  were  possible:  (1)  a  comparison  with 
Archaic  groups,  the  Lenid  or  Iswanid  varieties;  (2)  a  comparison  with 
more  recent  groups  such  as  the  Muskogid  or  Ilinid  varieties;  or  (3)  with 
a  more  modern  variety,  the  Dakotid  of  the  Plains.    The  Lenid  variety  is 


90  Indiana  Academy  of  Science 

represented  in  the  coastal  Algonkian  populations,  which  are  unlike  the 
Tutelo,  and  was  ruled  out  as  unlikely  to  bear  much  similarity.  The 
Dakotid  groups  are  very  unlike  the  Eastern  Siouan  material  morpho- 
logically, and  were  likewise  ruled  out.  The  Ilinid  variety  is  geograph- 
ically less  likely  to  be  related  to  the  Eastern  Siouans  than  the  remaining 
groups,  the  Muskogid  and  the  Iswanid.  There  is  a  strong  possibility 
that  the  Muskogid  groups  may  be  related  to  the  Southern  or  Catawba 
Eastern  Siouans,  and  this  is  also  suggested  linguistically,  but  there  is 
no  Catawba  material  available.  The  Iswanid  variety  bears  obvious 
morphological  resemblance  to  the  Tutelo  sample,  and  the  type  series  for 
this  variety  is  the  Indian  Knoll  population  responsible  for  the  Indian 
Knoll  culture  which  closely  links  the  Eastern  Sioux  with  the  Ohio  Valley 
area.  A  rigorous  statistical  analysis  and  comparison  of  the  Indian  Knoll 
Iswanid  series  and  the  Tutelo  Eastern  Siouan  series  was  therefore  under- 
taken, and  the  linguistic,  archaeological,  and  racial  traits  correlated  to 
find  the  best  fit,  an  explanation  of  the  origin  of  the  Tutelo  Eastern 
Sioux. 

The  statistical  methods  used  in  the  complete  analysis  and  comparison 
were  the  F  test  for  homogeneity  of  variance  of  the  two  samples,  upon 
which  the  t  test  for  significant  difference  in  means  was  based.  A  fur- 
ther test  for  significant  difference  in  means  was  employed,  the  3 
X.P.Es  test,  or  three  times  the  probable  error  of  the  difference  between 
the  means.  The  results  were  virtually  identical  in  each  case,  and  may  be 
considered  highly  reliable.  Morphological  observations  were  also  compiled 
in  tables  of  frequency  distribution  for  each  observation.  The  computa- 
tions for  the  various  statistical  tests  employed  were  done  through  the 
facilities  of  the  Research  Computing  Center  at  Indiana  University. 

The  Tutelo  Eastern  Siouan  skull  may  be  briefly  described  as  follows: 
the  skull  is  medium  in  size,  with  a  glabello-occipital  length  of  182.2  mm., 
a  maximum  breadth  of  137.1  mm.,  and  a  basion-bregma  height  of 
137.4  mm.  These  dimensions  yield  a  cranial  index  of  75.24,  and  a  length- 
height  index  of  75.44.  The  cranial  vault  is  therefore  on  the  lower  border 
of  mesocrany  and  high  in  relation  to  its  length.  It  is  ovoid  in  form, 
with  medium  muscular  relief,  large  to  very  large  divided  brow  ridges, 
medium  frontal  height  and  slope,  small  to  medium  frontal  breadth,  a 
slight  amount  of  sagittal  cresting,  medium  parietal  eminences,  medium 
lambdoid  flattening,  and  an  occiput  with  medium  curve  and  low  position. 
The  face  as  a  whole  is  of  moderate  and  not  rugged  build,  and  not  large 
in  relation  to  the  braincase.  All  facial  dimensions  tend  to  be  moderate, 
with  a  total  facial  height  of  117.9  mm.,  an  upper  facial  height  of 
71.1  mm.,  and  a  total  facial  breadth  of  133.1  mm.  The  indicial  pro- 
portions are  also  moderate,  with  a  total  facial  index  of  88.6, 
mesoprosopic,  and  and  upper  facial  index  of  53.51,  mesene.  The 
size  and  height  of  the  zygomatic  bones  are  medium,  and  the 
anterior  projection  of  the  zygomatics  is  small  to  medium.  The  lateral  pro- 
jection of  the  zygomatics  is  less  moderate,  and  is  medium  to  large.  The 
orbit  shape  is  most  frequently  square,  often  rhomboid,  with  a  small  to 
medium  amount  of  inclination.  The  left  orbital  index  is  80.82  if  the 
breadth  is  taken  from  maxillofrontale,  and  85.30  from  dacryon.    The  first 


Anthropology  91 

index  is  mesoconch,  the  second  barely  falls  into  the  hypsiconch  indicial 
category.  The  nasal  index  is  48.28,  or  mesorrhine.  Absolute  diameters 
of  the  nasal  structures  are  small,  with  a  nasal  breadth  of  24.1 
mm.,  and  a  nasal  height  of  50.0  mm.  Both  nasal  root  and  bridge 
dimensions  are  moderate;  the  nasal  root  breadth  small  to  medium,  the 
nasal  bridge  medium,  and  the  nasal  bridge  breadth  small  to  medium. 
Midfacial  prognathism  is  absent  to  slight;  aveolar  and  total  prognathism 
are  slight.  The  size  of  the  mandible  is  medium.  The  most  common  chin 
form  is  bilateral,  with  a  wide  bilateral  the  modal  subtype.  Gonial  eversion 
is  varied,  but  predominantly  small.  In  a  description  of  this  nature,  the 
Tutelo  Eastern  Siouan  skull  is  found  to  be  virtually  identical  with  the 
Indian  Knoll  Iswanid  series.  Computer  analysis  at  the  sensitivity  level 
of  the  t  test  for  significant  difference  in  means  between  the  two  series 
reveals  only  nine  significant  differences  out  of  thirty-four  measurements, 
five  significant  differences  out  of  twenty-three  indices,  and  five  significant 
differences  out  of  seventy-eight  morphological  observations.  These  dif- 
ferences may  be  attributed  to  the  slightly  larger  Tutelo  skull,  and  repre- 
sent variation  well  within  the  limits  of  a  local  series  of  a  variety. 

The  consideration  of  the  linguistic,  ethnohistorical,  and  archaeologi- 
cal evidence  available,  and  the  detailed  metric  and  morphological  analysis 
of  the  available  Eastern  Siouan  skeletal  material  leads  to  the  following 
conclusions: 

1.  The  Tutelo  Eastern  Siouan  cranial  series  exhibits  a  high  degree  of 
similarity  with  Neumann's  Iswanid  variety  as  represented  by  the 
Indian  Knoll  series.  The  metric  differences  between  the  two  series,  such 
as  the  slightly  larger  Tutelo  skull  and  the  slightly  higher  Iswanid  vault 
represent  local  differences  which  would  be  expected  considering  the  time 
span  separating  the  two  series  and,  when  viewed  in  the  light  of  the 
great  majority  of  measurements  and  indices  which  exhibit  no  statistically 
significant  difference,  are  not  sufficient  to  negate  the  conclusion  that  the 
Tutelo  Eastern  Siouan  series  is  representative  of  the  Iswanid  variety  of 
American  Indian.  Morphologically,  the  two  series  are  also  extremely 
similar,  and  the  morphological  observations  substantiate  the  metric  data 
completely.  The  Tutelo  Eastern  Siouan  series  may  then  be  described  as 
a  local  series  of  the  Iswanid  variety,  with  the  differences  between  them 
and  the  type  series  being  negligible  on  a  varietal  level. 

2.  From  the  standpoint  of  methodology,  this  study  has  demon- 
strated that  the  use  of  the  combination  of  metric,  indicial,  and  morpho- 
logical characteristics  as  employed  by  G.  K.  Neumann  (6)  along  with 
tests  of  statistically  significant  differences  in  means  such  as  the  t  test  and 
the  3  X.P.Es.  test  is  sufficiently  sensitive  to  detect  minor  differences  and 
therefore   adequate   for  historical   reconstruction. 

3.  The  correlation  of  the  linguistic  picture,  the  archaeological  and 
ethnohistorical  evidence,  and  the  physical  evidence  assembled  in  this 
paper  provide  a  new  insight  into  the  origins  of  the  Eastern  Siouan 
peoples.  The  first  detailed  description  of  Eastern  Siouan  crania  which 
can  be  documented  as  to  their  tribal  affiliation  has  been  provided,  and

the  connection  with  the  Archaic  Iswanid  variety  makes  a  contribution  in 
linking  prehistoric  archaeological  manifestations  with  historic  tribes.  It 
has  been  shown  that,  of  the  Eastern  Sioux  the  Tutelo  are  linguistically 
more  closely  related  to  the  Western  branch  of  the  Siouan  family  than  to 
the  other  Eastern  group,  and  the  ethnohistoric  evidence  available 
strongly  points  to  an  Ohio  Valley  origin  for  the  Eastern  Sioux.  The 
archaeological  evidence  demonstrates  the  similarity  between  the  Badin 
Focus  of  the  Carolina  Piedmont,  which  appears  directly  ancestral  to  the 
historic  Eastern  Siouan  groups,  and  the  Indian  Knell  culture  of  Ken- 
tucky, of  which  the  Iswanid  physical  type  is  representative.  Finally,  the 
physical  evidence  presented  demonstrates  the  varietal  relationship 
between  the  Tutelo  Eastern  Siouan  series  and  the  Iswanid  series  of 
Indian  Knoll.  Therefore,  from  the  evidence  available  from  linguistics, 
archaeology,  and  physical  anthropology,  the  conclusion  is  reached  that 
the  origin  of  the  Eastern  Siouan  peoples  can  now  be  connected  more 
strongly  to  the  Ohio  Valley  area  than  was  previously  possible.

The  Middle  Ohio  Valley  has  known  the  presence  of  man  from  pre- 
historic times  to  the  present  day.  Until  the  coming  of  the  White  settlers, 
the  aboriginal  inhabitants  of  the  valley  directed  most  of  their  energies 
toward  obtaining  food  in  sufficient  quantities  to  permit  survival  and 
perpetuation  of  their  social  group.  Some  subsistence  patterns,  such  as 
agriculture,  involved  greater  cultural  elaboration  of  material  items, 
whereas  less  diversity  in  the  material  traits  generally  are  associated  with 
earlier  hunting  and  gathering  populations.  In  other  words,  the  earlier 
inhabitants  of  the  Middle  Ohio  Valley  concentrated  on  practicing  their 
culture  and  left  some  of  its  products  in  passing.  Although  the  more 
recent  immigrants  to  the  region,  the  White  settlers,  were  also  interested 
in  populating  the  area  and  gaining  a  living  from  it,  they  brought 
a  new  interest  with  them.  They  were  inquisitive  about  the  earlier  occu- 
pants whose  cultural  items  were  frequently  found  on  the  surface  of  the 
ground  or  when  the  soil  was  cultivated.  As  a  result,  considerable  atten- 
tion was,  and  continues  to  be,  devoted  to  the  location,  description,  and 
identification  of  the  cultures  of  the  prehistoric  inhabitants.  Nor  is  inter- 
est in  extinct  cultures  confined  to  the  professionally  trained  investigator, 
as  a  perusal  of  early  historic  journals  will  illustrate.  More  frequently, 
it  has  been  the  amateur  investigator  who  finds  evidence  of  aboriginal 
occupations  and  who  calls  it  to  the  attention  of  the  trained  specialist. 
Within  the  last  one  hundred  years,  many  prehistoric  sites  have  been 
found  and  subsequently  given  particular  names  in  terms  of  location,  of 
temporal  placement,  and  of  the  material  remains  found  on  the  site.  Often 
times  items  of  the  material  culture  are  found  in  association  with  physical 
remains  of  the  population,  and  it  then  becomes  possible  to  study  not 
only  the  life  ways  of  the  people  but  to  study  the  people  themselves. 

An  attempt  is  made  here  to  reconstruct  the  history  of  the  people 
who  produced  the  Fort  Ancient  archaeological  cultural  assemblage  by 
using  a  multidisciplinary  approach  toward  the  solution  of  a  historic 
problem.  Specifically,  a  test  is  made  to  ascertain  to  what  extent  the 
physical  data  of  the  Fort  Ancient  Aspect  population  support  the 
conclusions  that  have  been  drawn  on  the  basis  of  archaeological  evidence. 

During  the  1930's,  Griffin  (2)  conducted  a  comprehensive  investiga- 
tion of  the  Fort  Ancient  archaeological  manifestation,  and  his  data  form 
the  foundation  for  the  descriptive  and  comparative  analyses  of  this 
preliminary  study.  He  establishes  four  foci  in  the  Aspect — Baum,  Feurt, 
Anderson,  and  Madisonville — on  the  grounds  of  artifactual  similarities 
and  differences;  the  same  foci  are  accepted  here  as  archaeological  sub- 
groupings.   The  skeletal  remains  associated  with  these  subgroupings  are

compared  with  each  other,  and  with  non-Fort  Ancient  groups,  to  denote 
the  various  degrees  of  physical  homogeneity  among  the  groups  within 
the  Aspect  and  to  determine  phyletic  relationships  with  other  groupings 
on  a  varietal  level. 

The  ethnohistorical  identification  of  the  earliest  tribes  found  in  the 
region  is  evaluated  against  the  archaeological  distribution  in  concordance 
with  the  temporal  position  of  the  Fort  Ancient  Aspect.  While  there  is 
the  possibility  that  the  earliest  historic  tribes  of  the  Middle  Ohio  Valley 
may  have  been  derived  from  Siouan-,  Muskogean-,  or  Algonquian- 
speaking  stocks,  it  is  most  probable  that  the  Fort  Ancient  people  were 
Algonquian  and  therefore  the  ancestors  of  the  historic  Shawnee  tribal 
group.  Working  with  the  assumption  that  the  people  in  the  area  were 
affiliated  with  the  Central  Algonquian  linguistic  group,  the  cultural  and 
physical  correlations  with  other  members  of  this  division  are  explored  to 
investigate  the  precise  temporal  and  spacial  placement  of  the  population. 

When  the  identification  of  an  archaeological  population  is  being 
attempted,  the  investigator  utilizes  the  morphological  and  metrical  data 
of  the  skeletal  remains  that  are  available  to  him.  The  morphological 
characteristics  serve  as  basic  units  since  they  more  readily  express  the 
features  that  are  typical  of  the  group.  The  metrical  dimensions  primarily 
yield  data  on  size  rather  than  form,  and  the  indicial  units  pertain  exclu- 
sively to  proportions,  eliminating  the  size  factor.  If  the  morphological, 
metrical,  and  indicial  traits  are  used  together  and  their  significant 
correlations  noted,  as  is  done  in  the  present  study,  the  population  may 
be  accurately  described  and  identified  in  terms  of  trait  combinations 
unique  to  it. 

The  cranial  material  of  the  Fort  Ancient  population  was  collected 
by  Georg  K.  Neumann  of  Indiana  University  during  the  time  that 
Griffin  was  gathering  the  archaeological  data  for  his  report.  The 
physical  remains  were  so  numerous  that  a  comprehensive  study  of  them 
was  not  feasible  until  computerized  programming  and  facilities  were 
available.  A  total  of  732  individuals  compose  the  Aspect  sample,  i.e., 
Baum  Focus  40,  Feurt  Focus  71,  Anderson  Focus  118,  and  Madisonville 
Focus  503.  Some  components  within  each  focus  were  excavated  more 
completely  than  others,  but  the  sample  is  considered  to  be  more  than 
adequate  in  providing  a  representation  of  the  physical  characteristics  of 
the  Fort  Ancient  people. 

In  this  preliminary  study  only  the  male  crania  of  approximately  300 
individuals  are  examined.  Since  occipital  cranial  deformation  is  dis- 
played among  a  number  of  the  crania,  it  is  necessary  to  establish  an 
undeformed  and  deformed  category  for  the  population  of  each  com- 
ponent, with  the  exception  of  the  components  of  the  Anderson  focus. 
The  comparisons  of  each  category  are  made  by  using  Student's  "t"  test 
(1),  a  statistical  means  of  determining  significant  differences  between 
small  populations  and  an  important  step  in  evaluating  which  traits 
would  provide  the  most  definitive  information  in  a  more  comprehensive 
multivariate  analysis.  The  assessment  of  population  distance  and  infer- 
entially,    the    problem    of    local    differentiation    versus    hybridization,    is 


Anthropology  95 

expressed  in  terms  of  t-ratios  and  t-probabilities.  An  estimate  of  popu- 
lation distance  is  obtained  from  the  ratio  of  significant  differences  found 
in  the  total  number  of  variables  for  each  measurement  and  index,  being 
expressed  as  a  coefficient  of  relatedness.  Although  the  coefficients  are 
based  on  a  continuum,  they  are  distributed  proportionally  in  index 
classes  to  indicate  near  identity,  close  relationship,  moderate  relation- 
ship, and  unrelatedness.  This  scale  serves  as  a  guide  in  determining 
whether  crania  from  different  components  display  homogeneous  or 
heterogeneous  physical  characteristics,  i.e.,  whether  the  crania  represent 
similar   or   dissimilar   physical   populations    (3). 

The  cranial  comparisons  are  made  on  three  different  levels — the 
intra-focus  level,  the  inter-focus  level,  and  the  varietal  level.  On  the 
intra-focus  level,  it  is  found  that  the  components  of  the  Baum  Focus  do 
not  represent  a  single  in-breeding  population,  but  the  series — the  unde- 
formed  and  deformed  crania — display  a  high  degree  of  similarity  in 
many  dimensions  and  indices  relating  to  traits  that  are  commonly  used 
to  delineate  populations.  The  crania  from  the  various  components  of 
the  Feurt  Focus  exhibit  little  physical  variability,  having  a  coefficient  of 
relatedness  of  near  identity.  The  series  from  the  Anderson  Focus  display 
only  a  slight  amount  of  physical  dissimilarity  and  appear  to  be  closely 
related.  The  crania  of  the  components  in  the  Madisonville  Focus  display 
less  physical  homogeneity  in  both  undeformed  and  deformed  groups 
than  is  found  in  the  other  foci.  The  degree  of  heterogeneity  strongly 
suggests  the  presence  of  more  than  one  physical  variety  in  the  focus. 

When  the  crania  of  each  focus  are  pooled  into  a  single  "focus" 
population  (maintaining  undeformed  and  deformed  categories  when 
necessary),  it  is  found  that  the  undeformed  crania  of  Baum,  Feurt,  and 
Anderson  Foci  appear  to  be  closely  related,  displaying  few  significant 
differences  in  dimensions  or  indices.  The  deformed  crania,  however, 
exhibit  a  number  of  significantly  differing  values  which  may  be  influenced 
by  the  type  and  degree  of  deformation  or  by  the  presence  of  more  than 
a  single  physical  variety.  The  Madisonville  crania  appear  to  be  only 
moderately  related  to  the  other  foci,  making  it  evident  that  more  than 
one  physical  type  was  involved  in  the  t-score  comparisons.  Hence,  the 
crania  of  the  Fort  Ancient  Aspect  cannot  be  pooled  to  represent  a  single 
homogeneous  population. 

An  examination  of  all  crania  suggested  that  the  undeformed  indi- 
viduals could  be  sorted  into  an  Ilinid  or  a  Muskogid  (Walcolid)  category 
in  accordance  with  the  predominating  physical  characteristics  of  each 
skull  in  order  to  investigate  the  presence  of  different  physical  types 
in  the  Aspect.  Smail  (4)  has  previously  shown  that  the  Anderson  popu- 
lation is  closely  related  to  the  Oakwood  Mound  people,  the  "type"  Ilinid 
physical  variety;  hence,  there  is  strong  evidence  for  building  the  Fort 
Ancient  Ilinid  population  around  the  series  from  the  Anderson  Focus. 
Undeformed  crania  from  the  Baum  Focus  and  some  components  of  the 
Madisonville  Focus  also  fit  into  the  Fort  Ancient  Ilinid  series.  The 
Fort  Ancient  Muskogid  series  is  composed  of  undeformed  crania  from 
the  Madisonville  Focus  since  there  is  little  evidence  of  this  physical 
variety  in  the  other  foci.

When  the  Fort  Ancient  "derived  varieties"  are  compared,  they  are 
found  to  be  unrelated  in  dimensional  values  and  only  moderately  related 
in  indicial  values.  However  the  Fort  Ancient  Muskogid  series  display 
less  of  a  population  distance  to  the  Fort  Ancient  Ilinid  series  than  to  any 
other  varietal  series  to  which  it  is  compared.  On  the  other  hand,  there  is 
conclusive  evidence  that  the  Fort  Ancient  Ilinid  series  is  nearly  identical 
to  the  Ilinid  physical  variety  and  moderately  related  to  the  Muskogid 
variety. 

According  to  various  radiocarbon  dates,  the  Fort  Ancient  culture 
covered  a  temporal  span  from  about  A.D.  1100  until  historic  times  with 
the  Baum  Focus,  and  its  Ilinid-like  population,  exhibiting  greater 
antiquity  than  the  other  foci.  The  Madisonville  Focus  appears  to  be 
nearly  as  old  as  Baum  and  exhibits  a  temporal  depth  beyond  the  radio- 
carbon dates  recorded  for  the  Anderson-like  components  of  Pleasant 
Hill  and  Erp.  Such  a  time  depth  for  Madisonville  would  account  for  the 
numerous  Ilinid-like  individuals  in  that  focus  and  would  suggest  that  the 
Fort  Ancient  Muskogid  physical  type  was  a  late  arrival  in  the  Aspect, 
coming  from  the  south.  Therefore,  it  is  proposed  that  the  Fort  Ancient 
Ilinid  peoples  represent  the  original  inhabitants  of  the  Fort  Ancient 
cultural  area  which  evolved  from  a  Woodland  base. 

The  small  sample  of  known  Shawnee  may  not  typify  the  entire  tribe, 
but  the  coefficients  of  relatedness  for  the  comparisons  of  the  Shawnee 
and  the  Fort  Ancient  "type"  series  imply  that  the  former  represent  an 
admixture  of  the  predominant  physical  types  in  the  area.  Since  some  of 
the  late  prehistoric  crania  display  similar  kinds  of  admixture,  it  is 
believed  that  the  historic  Shawnee  peoples  are  the  descendants  of  the 
Fort  Ancient  archaeological  population  and  are  not  recent  comers  to 
the  Middle  Ohio  Valley.  The  fact  that  the  Shawnee  crania  exhibit  some 
Muskogid  characteristics  is  considered  to  be  merely  an  indication  of  the 
degree  of  admixture  that  is  present  in  early  historic  times,  but  it  is 
believed  that  the  prehistoric  Shawnee  were  more  like  the  Fort  Ancient 
Ilinid  variety.  The  Ilinid  affiliation  of  the  Fort  Ancient  population,  the 
early  Shawnee,  is  substantiated  by  a  recent  study  of  a  Fort  Ancient 
series  from  Central  Indiana  that  was  made  by  Neumann.  He  found  that 
the  crania  appear  to  be  closely  related  to  the  Anderson  population,  or  the 
Fort  Ancient  Ilinid  variety.  Thus,  it  appears  that  the  Fort  Ancient 
archaeological  manifestation  and  the  prehistoric  Shawnee  are 
coterminous.

Urban  Anthropology  and  the  Southern  Mountaineer 

Ben  R.  Huelsman,  Indiana  University 

Abstract 

As  a  science  Anthropology  is  a  little  over  a  hundred  years  old.  In  the 
nineteenth  century,  cultural  anthropologists  pioneered  the  concept  of  cul- 
ture and  were  primarily  concerned  with  describing  and  recording  the  ways 
of  life  of  so-called  primitive  peoples,  such  as  the  American  Indian  and  the 
peoples  of  Africa  and  Asia.  Since  World  "War  II,  many  of  these  ethnic 
groups  comprise  the  emergent,  independent  nations.  Meanwhile,  the  twen- 
tieth century  has  caught  up  with  Anthropology,  and  less  than  nine  percent 
of  the  U.S.  labor  force  is  directly  engaged  in  agricultural  pursuits.  Our 
cities  are  filling  up  with  formerly  rural  peoples,  American  Indians  moving 
to  the  city  slums  and  away  from  federal  reservations.  Millions  of  blacks 
from  the  rural  South  have  migrated  northward  to  find  their  dreams  of 
freedom  frustrated  in  the  black  ghettoes  of  our  major  cities.  This  is  a 
story  of  a  less  well-studied  group  of  migrants,  the  southern  mountain 
white,  with  whom  I  worked  in  two  different  slums  for  seven  years.  Since 
more  than  eighty  percent  of  all  Americans  live  in  or  near  cities,  it  is 
apparent  that  a  subfield  of  Urban  Anthropology  will  emerge. 

Introduction 

The  1970  census  will  probably  reveal  that  about  eighty  percent  of 
U.S.  citizens  reside  in  the  metropolitan  areas  of  this  nation.  There  seems 
to  be  little  doubt  that  these  urban  areas  now  face  a  bewildering  array  of 
extremely  serious  problems.  In  an  age  of  growing  militancy  of  all  kinds, 
the  need  for  utilizing  the  best  thinking  of  all  the  behavioral  sciences 
toward  the  solution  of  these  urban  crises  has  never  been  greater.  As  one 
of  the  behavioral  sciences,  anthropology  ought  to  be  in  a  position  to 
make  many  contributions  to  the  solution  of  urgent  national  problems, 
especially  those  of  our  cities.  In  the  last  third  of  the  twentieth  century 
many  detribalized  ethnic  groups  will  migrate  to  the  slums  of  cities  in  the 
developing  countries  in  ever-increasing  numbers.  In  our  own  country, 
large  numbers  of  American  Indians  have  left  their  reservations  to 
migrate  to  Chicago,  Denver,  and  Los  Angeles.  It  is  quite  predictable  that 
they  are  met  by  police,  employment  officials  and  welfare  workers  who  lack 
even  the  most  rudimentary  training  in  cultural  anthropology.  Here  is  at 
least  one  situation  in  some  of  our  cities  for  which  the  professional 
anthropologist  ought  to  be  able  to  develop  a  working  program  of  applied 
anthropology.  In  addition  to  growing  numbers  of  American  Indians  who 
have  migrated  to  our  industrial  centers,  there  are  other  ethnic  groups 
whose  presence  in  big  city  slums  creates  problems  for  both  the  cities  and 
the  migrants  themselves.  One  of  these  groups  is  the  southern  moun- 
taineer. An  estimated  two  million  of  them  live  in  our  midwestern  indus- 
trial centers.  Cultural  anthropologists  in  the  United  States  have  studied 
the  American  Indian  intensively  for  more  than  a  century.  With  the 
exception  of  Prof.  Marion  Pearsall  of  the  University  of  Kentucky,  few 
anthropologists  in  this  country  have  been  concerned  with  studying  or 
helping  the   southern  mountain  man  and  his  family.

Most  of  the  graduate  schools  of  anthropology  in  the  United  States 
do  not  offer  a  course  or  seminar  in  Urban  Anthropology.  One  of  the 
themes  of  this  paper  is  that  there  should  be  such  a  course  developed 
experimentally  in  departments  of  anthropology  all  over  the  United 
States.  I  visualize  such  a  course  as  being  offered  in  the  evenings,  not 
during  the  daytime  hours,  so  that  local  government  officials,  policemen, 
social  workers  with  no  training  in  anthropology  and  other  urban  officials 
might  attend.  After  I  received  my  M.A.  in  anthropology  I  had  the  ex- 
perience of  working  for  seven  years  in  the  cities  of  Cincinnati  and  Day- 
ton, Ohio  with  the  southern  mountaineer  and  his  children.  I  often 
attended  workshops  and  conferences  sponsored  by  the  Mayor's  Friendly 
Relations  Committee  in  Cincinnati,  the  purpose  of  which  was  to  examine 
all  aspects  of  the  culture  and  urban  adjustment  of  migrants  to  that  city, 
both  black  and  white.  As  it  became  generally  well  known  that  I  was  the 
only  person  in  attendance  with  an  advanced  degree  in  anthropology,  I 
became  acutely  aware  of  the  image  of  anthropology  in  the  United  States 
which  is  held  by  such  urban  officials.  It  goes  something  like  this.  Anthro- 
pology is  viewed  as  the  study  of  primitive  peoples,  especially  the  Ameri- 
can Indians.  The  best  known  fields  of  anthropology  are  archeology  .  .  . 
based  on  newspaper  accounts  of  recent  digs  and  ethnology,  usually 
associated  with  the  paperback  books  of  Margaret  Mead.  To  persons  who 
have  never  studied  anthropology,  the  field  is  seen  as  an  impractical, 
romantic  collection  of  interesting  data  about  exotic,  tribal  groups.  In 
other  words,  anthropology  as  they  see  it,  cannot  possibly  have  any 
real  bearing  on  the  kinds  of  practical  problems  such  urban  administrators 
and  workers  face  on  a  daily  basis.  This  is  a  stereotype,  obviously.  The 
point  is  that  this  stereotype  is  widely  believed  and  acted  on  as  though 
it  were  a  reality  by  many  responsible  officials  in  major  American  cities. 
I  might  add  that  nothing  remotely  resembling  a  course  in  Urban  Anthro- 
pology was  ever  offered  at  either  the  University  of  Cincinnati  nor  at  the 
University  of  Dayton.  It  is  quite  true,  that  unlike  Chicago  or  Denver, 
there  are  no  American  Indian  migrant  groups  in  the  slums  of  these  two 
cities,  nevertheless  the  southern  rural  black  and  the  white  mountaineer 
arrived  by  the  thousands  every  year  in  these  cities.  No  anthropologist 
studied  these  groups. 

In  my  experience  with  the  southern  mountaineers  in  both  Cincinnati 
and  Dayton,  Ohio,  I  noticed  that  their  behavior  varied  according  to  the 
section  of  the  city  in  which  they  lived.  I  also  observed  that  these  patterns 
of  behavior  differed  in  relationship  to  the  length  of  time  these  people 
had  resided  in  the  city.  One  of  the  critical  factors  in  determining  the 
future  adjustment  of  a  mountain  family  to  an  urban  environment  is 
whether  or  not  the  male  head  of  the  family  is  able  to  find  steady  employ- 
ment. The  folk  class  mountain  parents  I  worked  with  tended  to  have  a 
median  level  of  education  of  about  eight  years  of  schooling  in  rural 
Appalachia.  This  is  a  male-dominant  subculture  in  which  the  future  way 
of  life  of  the  entire  family  is  directly  tied  to  the  occupational  success  or 
failure  of  the  father.  Thus  the  success  or  failure  of  the  father  in  finding 
steady  employment  in  a  factory  or  garage  usually  determined  to  some 
extent  the  future  residence  of  the  family  in  the  city.  Some  made  it  to

home  ownership  in  an  inexpensive  suburb,  others,  failing  to  find  steady 
employment  for  some  reason  or  other,  entered  the  drab,  barracks-like 
existence  of  welfare-recipients  in  a  low-cost  public  housing  project.  By 
far  the  largest  group  of  migrant  mountaineers  are  the  more  recent 
arrivals  to  the  city,  usually  found  in  an  ageing  slum  district  which  is 
known  as  the  port  of  entry. 

The  basic  premise  of  this  paper  is  that  there  are  three  life  styles 
to  be  found  among  the  southern  mountaineers  in  any  urban  community. 
Each  life  style  consists  of  patterned  behavior  which  differs  from  that 
observed  in  other  parts  of  the  city  where  the  southern  mountaineer  clus- 
ters. The  port  of  entry  life  style  will  be  described  first.  The  description 
will  be  as  non-technical  as  possible  to  avoid  cumbersome  language  and 
technical  jargon.  In  Dayton,  Ohio,  for  example,  the  port  of  entry  slum 
district  is  the  first  part  of  that  community  with  which  the  newly  mi- 
grated southern  mountaineer  becomes  familiar,  while  he  is  looking  for 
a  job.  It  is  here  that  he  hopes  to  break  out  of  the  intergenerational 
poverty  that  is  choking  to  death  so  many  of  his  kinsmen  in  rural  Appa- 
lachia.  Here  is  a  sketch  of  the  port  of  entry  life  style  in  Dayton. 

Port  of  Entry  Life  Style 

There  is  no  deep  sea  harbor  in  Dayton  and  no  plans  to  dredge  one. 
There  is  no  Ellis  Island  either  to  bring  migrants  from  across  the  ocean 
in  great  sailing  ships.  But  like  Indianapolis,  Dayton  has  a  port  of  entry 
for  its  immigrants,  and  most  of  them  speak  the  softly  slurred  speech  of 
the  rural  South,  not  the  tongues  of  Eastern  Europe.  There  is  no 
immigration  service  in  the  city  to  count  their  numbers  but  it  is  known 
they  are  both  black  and  white,  many  of  them  making  less  than  the  pover- 
ty level  of  three  thousand  dollars  a  year.  You  won't  find  them  at  the  local 
airport  either.  Most  air  travellers  are  middle  class  professional  and  busi- 
nessmen, not  former  sharecroppers  and  out  of  work  coal  miners.  The 
migrant  to  Dayton  usually  gets  here  in  a  wheezing  old  car  full  of  kids 
with  hungry  bellies  and  maybe  a  guitar.  In  the  pocket  of  his  faded, 
blue  work  shirt  is  a  letter  from  a  second  cousin  or  an  uncle  with  an 
address  near  Fifth  and  Brown  or  Tecumseh  St.  in  East  Dayton.  This  is 
in  the  heart  of  Dayton's  port  of  entry,  a  strange  new  style  of  life  for 
the  southern  white  mountain  migrant.  He  brings  his  wife,  four,  five  or 
six  children  and  about  eight  years  of  grammar  schooling  because  he's 
heard  from  his  kinsman  that  "they're  hirin'  on  at  NCR"  or  somewhere 
else.  The  southern  mountain  man  in  the  port  of  entry  is  most  likely  to 
be  from  one  of  the  mountain  counties  of  Eastern  Kentucky.  His  kinsman 
on  Tecumseh  or  Brown  St.  has  four  or  five  young  'uns  of  his  own,  but 
he'll  not  turn  down  Dayton's  newest  migrant.  They  will  all  pile  into  one 
big  flat,  sleeping  on  couches,  on  the  floor  or  in  nice  weather,  maybe  some 
of  the  kids  will  sleep  out  in  the  car.  The  family  baggage  is  meagre  .  .  . 
a  few  changes  of  old  clothes,  a  toy  or  so,  some  snapshots,  a  few  trinkets 
and  souvenirs  of  life  back  home  in  the  hills  and  hollows  of  Eastern 
Kentucky.  The  family  has  brought  the  most  important  baggage  of  all 
with  them  .  .  .  the  culture  of  the  southern  mountaineer,  unfamiliar  with 
city  life.

Most  of  the  families  in  the  port  of  entry  hail  from  Eastern  Ken- 
tucky, with  a  few  from  rural  Tennessee  and  a  handful  from  West  Vir- 
ginia. The  much-abused  term  "ghetto"  hardly  applies  to  this  section  of 
Dayton.  Given  any  kind  of  choice,  the  migrants  from  Appalachia  would 
probably  decide  they  would  rather  live  near  each  other.  It's  easy  to 
come  across  friends  and  kin  from  the  same  county  just  a  block  or  two 
away.  They  have  the  same  background,  share  common  values  and  the  old- 
timers  in  the  port  of  entry  probably  offer  a  lot  of  practical  help  to  the 
just-arrived  friend  or  kinsman  from  Eastern  Kentucky.  The  newcomers 
soon  learn  where  the  flats  for  rent  are,  that  you  usually  pay  by  the  week 
and  in  advance.  They  also  learn  that  it's  pretty  hard  to  get  a  Dayton 
landlord  to  rent  to  a  family  from  Eastern  Kentucky  with  a  lot  of  kids, 
except  of  course  in  the  port  of  entry.  For  a  few  weeks  the  newcomer 
and  his  family  may  live  with  a  relative  or  friend  while  the  father  looks 
for  a  job.  In  the  meantime  his  wife  may  be  able  to  line  up  a  temporary 
job  as  a  waitress  or  barmaid,  probably  the  first  time  she  has  ever  been 
a  wage  earner.  When  this  happens,  the  oldest  daughter  in  the  family 
usually  takes  the  place  of  the  mother,  even  if  it  means  staying  out  of 
school.  Mountain  men  and  their  wives  seldom  go  out  socially  together. 
They  each  have  their  friends  and  acquaintances  of  the  same  sex  as 
themselves.  In  the  jargon  of  the  social  sciences,  these  are  called  refer- 
ence groups.  If  a  man  works  on  the  assembly  line  at  a  plant,  some  of 
his  cronies  on  a  Friday  or  Saturday  night  are  likely  to  be  co-workers 
and  others  may  be  immediate  neighbors.  The  fathers  will  probably  get 
together  on  a  regular  basis  at  certain  bars  and  at  least  one  or  more  of 
them  will  be  heavy  drinkers.  The  middle  class  world  of  P.T.A.s  joining 
the  Junior  Chamber  of  Commerce  and  involvement  in  community-wide 
projects  is  not  for  the  southern  mountain  man.  He  is  likely  to  be  a 
union  man  and  if  he  hasn't  backslid,  may  belong  to  a  storefront  church, 
much  like  the  ones  they  have  down  home.  His  religion  is  intensely  per- 
sonal, promising  immediate  salvation  and  offering  the  kind  of  emotional 
release  not  to  be  found  in  a  suburban  church.  The  mountain  man  is 
proud  and  fiercely  independent,  but  not  much  of  a  joiner,  and  he'd  just 
as  soon  snoopy  social  workers  left  him  and  his  family  alone,  as  he 
doesn't  like  outside  interference. 

The  economics  of  the  port  of  entry  differs  greatly  from  that  of 
Kettering  or  Huber  Heights  in  many  ways.  The  southern  white  migrant 
is  attuned  to  an  existence  of  weekly  payments.  Local  furniture  and 
clothing  stores  encourage  this  deliberately  and  often  charge  the  migrant 
family  exorbitant  rates  of  interest  for  their  garish,  poorly  made  prod- 
ucts. When  the  credit  manager  notices  that  only  a  few  more  weekly 
payments  remain,  the  family  is  encouraged  to  add  something  else  onto 
the  bill,  whether  they  need  it  or  not.  In  an  inflationary  economy  it  is 
difficult  for  most  people  to  develop  budgeting  skills  even  when  the 
family  size  is  small  and  the  income  adequate.  It  is  even  more  difficult 
for  the  mountain  family,  unaccustomed  to  high  prices,  not  used  to  han- 
dling the  unexpectedly  larger  salary  in  the  city  and  the  attractive  lure 
of  easy  credit.  Slumlords  know  their  customers  well  in  the  port  of 
entry  .  .  .  all  too  well.  They  know  the  migrant  is  desperate  for  a 
place   to   stay,   that  most  areas   of   Dayton  will  not   rent  to   him   on   a 


Anthropology  101 

monthly  basis  if  he  has  too  many  children  and  uncertain  job  prospects. 
Besides,  if  the  migrant  gives  up  in  defeat  and  slips  off  quietly  for  East- 
ern Kentucky,  at  least  the  landlord  will  lose  only  a  week's  rent,  not  a 
month's  rent.  It  is  also  true  that  coming  from  the  grinding  poverty  of 
Eastern  Kentucky,  that  the  migrant  is  not  likely  to  have  much  experi- 
ence in  caring  for  his  own  home.  Mountain  youngsters  are  apt  to  be 
given  the  same  kinds  of  unsupervised  freedom  they  enjoyed  back  home, 
where  there  wasn't  much  else  to  do  but  roam  free  in  the  cool  green  hills 
and  hollows.  A  boy  or  girl  in  Eastern  Kentucky  can  do  a  lot  of  this 
without  getting  into  trouble  with  the  law,  because  there  are  few  oppor- 
tunities for  delinquent  behavior  in  such  a  rural  environment.  The  mi- 
grant newcomer  to  the  port  of  entry  doesn't  realize  he  is  bringing  his 
children  to  one  of  the  highest  delinquency  rate  areas  of  Dayton.  In 
East  Dayton,  the  same  casual  parental  supervision  can  lead  to  a  police 
arrest  and  a  referral  to  the  Montgomery  County  Juvenile  Court. 

There  are  few  large  cities  in  Appalachia,  the  rural  areas  are  not 
heavily  policed  and  a  boy  who  gets  into  trouble  in  Eastern  Kentucky  is 
not  likely  to  be  arrested  and  hailed  into  a  juvenile  court.  If  a  sheriff 
does  arrest  a  boy  in  a  mountain  county  he  is  likely  to  reprimand  him 
on  the  spot  or  take  him  home  where  the  sheriff  will  be  personally  ac- 
quainted with  the  boy's  family.  If  a  boy  steals  from  a  neighbor  the  two 
families  are  inclined  to  try  to  work  it  out  in  a  personal,  face  to  face 
manner,  without  calling  in  a  constable  or  sheriff.  Fights  occur  at  roller 
rinks,  outhouses  get  dismantled  and  sometimes  tires  or  gasoline  are 
stolen  in  rural  Appalachia  and  some  of  this  never  gets  recorded  for  the 
benefit  of  statisticians.  Still,  there  isn't  as  much  juvenile  delinquency 
in  rural  Appalachia  as  in  the  port  of  entry  slum  of  any  large  midwestern 
city.  The  sheer  numbers  and  high  level  of  efficiency  of  the  Dayton  Police 
Department  ensure  that  a  fair  percentage  of  delinquent  children  in  the 
port  of  entry  will  eventually  be  apprehended,  especially  the  recidivists 
or  repeaters.  The  schools,  flats,  streets  and  alleys  of  the  port  of  entry 
are  well  known  and  heavily  travelled  by  an  army  of  police  officers,  social 
workers,  probation  officers  and  visiting  teachers. 

When  the  mountain  man  brings  his  wife  and  children  to  Dayton  he 
often  betters  himself  financially  by  going  from  a  chronically  unem- 
ployed, hopeless  way  of  rural  poverty  to  a  well  paying,  highly  skilled 
factory  job.  But  the  real  price  he  pays  for  pulling  up  his  cultural  roots 
in  Eastern  Kentucky  and  transplanting  them  to  the  port  of  entry  is 
often  paid  by  a  son  or  daughter  who  someday  winds  up  in  the  Boys 
Industrial  School  or  the  Girls  Industrial  School.  In  the  city,  justice  is  a 
vast,  faceless  bureaucracy  of  police,  probation  officers  and  social  work- 
ers. They  are  all  strangers  and  most  of  them  uphold  different  cultural 
values  from  the  southern  white  migrants.  The  person  to  person  ways  of 
handling  family  crises  back  home  don't  seem  to  work  in  the  vast, 
impersonal  sterile  environment  of  the  city. 

Welfare-Dependency  Life  Style 

In  Dayton,  Ohio  there  is  a  public  housing  project  known  as  Parkside 
Homes.  There  are  many  southern  mountaineers  residing  in  this  project. 


102  Indiana  Academy  of  Science 

Their  way  or  life  is  quite  different  from  their  fellow  migrants  in  the 
port  of  entry.  I'll  call  this  the  welfare-dependency  life  style.  One  of 
the  basic  requirements  in  most  cities  for  welfare  benefits  is  a  residency 
requirement  of  not  less  than  one  year  in  the  city.  Unlike  some  of  the 
migrants  in  the  port  of  entry,  the  Parkside  Homes  mountain  family  has 
usually  been  in  the  city  some  time.  The  family  is  most  often  intact,  con- 
sisting of  both  parents  and  anywhere  from  three  to  seven  children.  The 
presence  of  the  male  head  of  the  household  in  the  Appalachian  migrant 
family  makes  the  social  structure  of  these  families  different  from  the 
so-called  matrifocal  family  of  the  welfare-dependent  black  families.  The 
role  of  the  wife  and  mother  in  projects  such  as  Parkside  Homes  is  not 
really  very  different  from  her  familiar  role  in  rural  Appalachia  or  in  the 
port  of  entry.  She  is  still  the  housekeeper,  cook,  laundress,  main  baby- 
sitter, nurse  to  younger  children  and  all  the  other  roles  acceptable  to 
mountaineer  women  regardless  of  where  they  live.  For  some  of  these 
mothers,  the  small  welfare  check  makes  possible  a  more  stable  supply 
of  food  than  they  have  known  since  their  marriage.  I  did  not  observe  a 
great  deal  of  voiced  discontentment  on  the  part  of  many  mothers  in 
Parkside  Homes,  even  on  the  many  occasions  when  I  had  the  opportuni- 
ties to  interview  them  alone.  The  children  young  enough  to  be  in  school 
do  not  seem  to  be  essentially  different  in  values  or  in  behavior  from 
similar  children  in  the  port  of  entry.  The  tendency  to  be  bored  with  the 
sedentary  school  curriculum  is  a  trait  shared  by  most  mountain  youth, 
irrespective  of  the  school  attended.  Parkside  Homes  is  no  stranger  to 
the  probation  officers  of  the  Montgomery  County  Juvenile  Court  and  the 
impression  is  that  the  delinquency  rate  in  this  small  housing  project,  if 
it  could  be  accurately  computed,  is  rather  high. 

In  my  experience  the  member  of  the  mountain  family  most  dam- 
aged by  the  welfare-dependency  life  style  is  the  father.  Without  a  job 
or  even  the  prospect  of  a  job,  the  mountain  man's  life  is  almost  without 
meaning.  For  this  man  Parkside  Homes  is  a  prison  cell  lined  with  velvet. 
The  reasons  why  he  cannot  find  employment  in  the  urban  labor  force  vary 
with  each  man  ultimately.  Sometimes  it  is  failing  health,  in  other  cases 
functional  illiteracy  or  alcoholism,  sometimes  a  combination  of  reasons. 
The  unemployed  mountain  man,  especially  if  he  gets  a  welfare  check, 
serves  unwittingly  as  the  model  for  the  city  stereotype  of  the  "lazy, 
shiftless  hillbilly."  For  some  reason  the  unemployed  mountain  man  is 
not  a  target  group  for  an  army  of  civil  rights  organizations  and  Federal 
programs.  His  problems  go  unpublicized  and  as  a  group,  the  southern 
mountaineer  is  not  organized.  Many  a  good  old  country  boy  from  Eastern 
Kentucky  has  arrived  in  the  port  of  entry  in  Dayton,  Ohio  only  to  find 
himself  in  Parkside  Homes  a  couple  of  years  later,  the  empty  years 
stretching  endlessly  ahead  of  him.  Under  such  conditions  and  especially 
coming  from  dry  counties  in  Eastern  Kentucky,  it  is  no  wonder  that 
so  many  turn  up  as  alcoholics  in  the  workhouse  or  Montgomery  County 
Jail.  The  older  teenage  son  of  such  a  man  always  has  the  hope  of  join- 
ing some  branch  of  military  service  when  he  drops  out  of  school,  espe- 
cially if  the  boy  cannot  find  a  job.  Today's  restrictive  labor  market,  with 
its  heavy  emphasis  on  increased  formal  education,  offers  even  less  to  the 


Anthropology  103 

high  school  dropout  of  both  races  than  was  true  only  two  decades  ago. 
The  mountain  lad  who  drops  out  of  school  today  at  age  sixteen  faces 
an  even  more  dismal  occupational  future  than  ever.  The  situation  be- 
comes even  more  hopeless  when  the  armed  services  demand  a  high  school 
diploma  of  potential  enlistees.  In  effect  this  means  that  still  one  more 
traditional  avenue  of  vertical  social  mobility  is  closing  to  the  under- 
educated  southerners  of  both  races.  The  implications  are  that  millions 
of  our  citizens  have  become  technologically  obsolete. 

The  Assimilated  Life  Style 

Above  Nettie  Lee  Roth  High  School  on  Hoover  Avenue  in  Dayton, 
Ohio  are  two  housing  developments,  namely  Townview  and  the  newer, 
brick  subdivision  of  Western  Hills.  There,  beginning  in  the  1960s,  one 
will  find  recently  arrived  groups  of  blacks,  enjoying  their  first  taste 
of  lower  middle  class  suburban  living.  But  for  the  most  part  the  ma- 
jority of  residents  in  these  two  developments  are  blue-collar  whites  and 
many  of  them  are  ultimately  from  rural  Appalachia.  A  great  many  of 
them  have  spent  their  apprenticeships  in  Dayton's  port  of  entry,  have 
successfully  found  jobs,  acquired  increases  in  job  skills  and  salary  levels 
and  bought  their  first  homes.  I  lived  in  the  Western  Hills  subdivision 
for  two  years  and  observed  many  of  these  people  at  first  hand.  The 
style  of  life  of  the  assimilated  mountaineer  differs  substantially  from 
that  of  the  southern  mountain  migrant  in  either  the  port  of  entry  or  in 
low  cost  public  housing  projects.  The  assimilated  mountaineer  is  drawn 
more  directly  into  the  middle  class  mainstream  of  urban  life  than  is 
true  of  the  other  two  groups.  Housekeeping  standards,  on  the  average, 
are  higher  than  is  generally  observed  in  the  decaying  tenements  of  the 
port  of  entry.  There  is  less  juvenile  delinquency  and  very  little  of  the 
regimentation  and  hopelessness  encountered  so  often  in  low  cost  housing 
projects.  Except  for  the  soft,  slurred  accents  of  the  southern  mountains, 
the  preference  for  Protestant  fundamentalism  and  country  music,  the 
assimilated  mountaineer  has  lost  much  of  his  distinctive  cluture.  As  long 
as  his  job  lasts,  the  assimilated  mountaineer  will  probably  never  again 
take  up  permanent  residence  in  rural  Appalachia,  although  on  long 
weekends,  he  is  likely  to  return  to  Eastern  Kentucky  to  visit  his  kin 
and  friends. 

In  summary,  I  have  argued  that  few  anthropologists  have  taken 
the  trouble  to  work  in  urban  environments  and  even  fewer  yet  are  in- 
clined to  study  the  southern  mountaineer,  either  in  rural  Appalachia  or 
as  a  migrant  to  our  industrial  centers.  To  what  extent  the  southern 
mountain  white  tends  to  fall  into  three  life  styles  in  other  cities  can 
only  be  confirmed  by  further  observation.  I  foresee  a  real  and  continuing 
need  for  the  skills  of  anthropologists  in  meeting  our  urban  problems. 
Does  anyone  agree  ? 


A  Systems  Approach  to  the  Study  of  Complex  Society 

Melford  S.  Weiss 

Sacramento  State  College 

Early  anthropological  research  was  conducted  among  simple,  non- 
literate,  self-sufficient,  hunting  or  quasi-agricultural  communities  which 
were  habitually  treated  as  cultural  isolates — where  contact  with  the 
outside-the-village  world  was  generally  regarded  as  inconsequential  or 
at  best  accidental.  Therefore,  the  society  in  question  was  invariably 
characterized  as  a  functionally  integrated  and  inter-related  whole,  a 
closed  system  with  built-in  homeostatic  mechanisms  which  would  remain, 
barring  further  contact,  in  a  state  of  "dynamic  equilibrium." 

As  research  interests  shifted  to  the  more  complex  peasant  societies, 
a  shift  which  demands  new  perspectives,  the  anthropologist,  nevertheless, 
brought  with  him  the  theoretical  models  accumulated  from  tribal  ven- 
tures. Robert  Redfiekl  (3)  clearly  established  the  peasant  upon  a  folk- 
urban  continuum;  and  although  the  peasant  still  retained  the  closeness 
of  face  to  face  primary  relationships,  a  deep  rooted  and  emotional  at- 
tachment for  the  soil,  and  the  warmth  of  Gemeinschaft  mythology,  there 
was  the  unavoidable  added  discomfort  of  a  relationship  to  the  greater 
outside  world.  Yet  in  spite  of  its  extra-village  contacts,  the  peasant 
community  was  generally  treated  as  a  geographically  and  culturally 
isolated  entity  whose  behavioral  dynamics  could  best  be  understood  by 
intensive,  internally-centered  research  activities. 

Today's  complex  rural  and  urban  communities,  in  both  the  western 
and  non-western  world,  can  no  longer  be  treated  as  cultural  isolates 
within  a  closed  system.  Any  study  of  changing  community  life  must 
account  for  that  community's  relationship  to  the  greater  and  invariably 
more  complex  outside  world.  Therefore,  communities  are  open  systems 
which  cannot  be  described  or  analyzed  in  terms  of  static  boundaries. 
The  focus  of  outside  contact  and  intervention  cannot  be  ignored,  for  it 
is  often  the  very  nature  of  the  relationship  to  the  external  world  that 
accounts  for  many  of  the  political,  economic,  social  and  ideological 
changes  taking  place  within  the  village  community. 

I  am  not  disclaiming  the  importance  of  village  studies,  nor  am  I 
suggesting  that  the  village  is  not,  to  some  degree,  a  functionally  inte- 
grated unit.  However,  it  is  time  to  take  another  look  at  the  world's 
communities  and  to  shift  our  emphasis  from  the  internal  aspects  of  the 
integrated  village  to  a  broader  and  more  comprehensive  understanding 
of  the  community  and  its  dynamic  linkage  to  the  rest  of  the   society. 

Because  a  village-centered  study  must  now  include  extra-village 
structural  ties,  I  would  like  to  present  one  approach  to  the  study  of  com- 
munity suggested  by  Professor  Ishino,  Donoghue,  Marquis  and  Alchin 
(1)  and  Marquis  (2)  of  the  Institute  for  Community  Development  at 
Michigan  State  University.

Anthropology  105 

The  Systems  Approach 

The  systems  approach  provides  both  a  method  and  a  model  for 
focusing  upon  a  community  and  its  connections  to  the  greater  society, 
because  it  views  the  community  in  terms  of  its  interactions  with  out- 
side institutions. 

Following  the  model  of  the  ecologists,  the  systems  approach  includes 
not  only  the  people  but  also  the  man-made  and  natural  components  with- 
in the  community;  it  focuses  upon  the  interaction  of  the  human 
components  with  the  man-made  and  natural  elements. 

A  community  "system"  also  includes  kinship,  economic,  educational, 
political,  religious  and  associational  institutions  which  are  linked  not 
only  to  each  other  but  to  their  counterparts  in  the  greater  society. 

Interaction  between  systems  takes  place  through  flows  or  movements 
of  material,  energy,  people,  and  information.  These  flows  are  con- 
tinually entering  and  leaving  the  system. 

The  Systems  Approach  and  the  Study  of  Billsburg 

In  1965  my  wife  and  I  completed  a  survey  study  of  a  semi-rural 
midwestern  community  with  a  population  base  of  2500  people.  If  the 
direction  of  our  study  had  been  internally  centered  and  oriented  in  a 
restrictive  and  definitive  temporal  and  spatial  framework,  instead  of 
an  open  system,  the  linkages  or  channels  which  connect  Billsburg  to  the 
greater  outside  world  and  the  flows  of  material,  energy,  people,  and 
information  along  these  channels  could  have  gone  unnoticed,  been  ig- 
nored, minimized,  "explained  away"  or  more  likely  merely  noted.  It  is 
because  Billsburg  was  specifically  viewed  as  a  system  constantly  inter- 
acting with  other  systems  at  the  local,  state,  national  and  even  inter- 
national level,  that  the  direction  and  nature  of  political,  social  and 
ideological  change  became  meaningful  and  integral  parts  of  the  study. 
(4) 

Flow  Analysis  as  a  Key  Towards  Understanding 
the  Interaction  Process  Between  Systems 

A  flow  is  any  movement  of  material,  energy,  people  and  informa- 
tion along  any  designated  channel  or  pathway,  either  between  different 
systems  or  within  a  single  system. 

For  example,  when  we  first  arrived  in  Billsburg,  we  spent  the 
better  part  of  the  first  day  standing  at  the  major  highway  intersection 
and  observed  the  traffic  patterns.  Traffic  in  Billsburg  is  basically  uni- 
directional; at  7:00  a.m.  the  concentration  is  westward  toward  Matson 
(a  local  urban  industrial  center),  at  5:00  p.m.  eastward  back  to  Billsburg. 
The  majority  of  the  cars  are  newer  models  in  the  lower  price  field.  Thus 
it  was  not  surprising  to  later  learn  that  approximately  seventy  percent 
of  working  Billsburgians  are  employed  in  the  greater  Matson  area,  that 
many  of  them  are  skilled  and  semi-skilled  workers  with  average  income 
of  $7,000,  and  that  Billsburg  has  overwhelming  strong  economic  ties  to 
the  Matson  area. 


106  Indiana  Academy  of  Science 

As  we  began  to  interview,  we  discovered  that  leisure  time  activities 
are  usually  spent  at  movies,  drive-ins,  restaurants,  bars,  and  bowling 
alleys,  many  of  which  are  located  outside  the  Billsburg  area,  and  at  the 
cultural,  social,  and  athletic  functions  of  Matson's  State  University. 

We  also  observed  that  Billsburg's  all-purpose  general  store  regu- 
larly subscribes  to  local,  county,  state  and  national  newspapers  including 
the  infamous  New  York  tabloids. 

While  many  major  flows  are  inter-system  oriented,  internal  (within 
the  system)  flows  are  also  of  considerable  importance.  My  wife  reported 
that  women  tended  to  do  their  daytime  shopping  at  the  larger  shopping 
centers  located  outside  the  Billsburg  city  limits  and  near  the  outskirts  of 
the  greater  Matson  area,  and  that  the  downtown  business  area  was 
poorly  populated,  causing  the  older  Billsburg  merchants  some  serious 
problems.  We  later  found,  as  one  might  suspect,  that  many  business 
enterprises  are  considering  relocation  closer  to  the  Matson  area.  (4) 

Thus  flows  of  material,  people,  and  information  are  helping  to 
establish  continuing  relationships  between  Billsburg  and  the  greater  Mat- 
son  area,  and,  as  previously  mentioned,  through  news  media,  with  the 
rest  of  the  nation.  Flow  analysis  should  never  be  the  end  product  of  the 
research  effort.  It  should  be  used  as  a  methodological  tool  which  is 
capable  of  providing  much  information,  especially  when  research  time- 
allocation  is  limited.  When  flow  analysis  is  coupled  with  other  research 
activities,  it  can  provide  immediate  and  valuable  insights  toward  under- 
standing the  dynamic  characteristics  of  any  community. 

The  Expanding  Nature  of  Contemporary  Society 

Many  problems  arise  within  the  community  because  the  community 
itself  is  in  a  transitional  (changing)  stage.  Many  of  the  internal  com- 
munity systems  have  expanded  to  the  point  where  they  are  no  longer 
subject  to  internal  controls.  This  often  results  in  organization  and 
influence  at  higher  administrative  levels,  and  consequent  conflict  situa- 
tions arise  which  cannot  be  explained  in  terms  of  the  village  alone. 

If  the  Methodist  Church  Council  in  Detroit  decided  to  send  a  Negro 
minister  to  Billsburg,  (since  Billsburg  is  still  associated  with  the  church 
hierarchy  in  Detroit,  such  a  move  is  possible)  the  one  hundred  percent 
white  Billsburg  congregation  would,  to  say  the  least,  certainly  be  affected 
by  such  a  decision. 

When  we  started  our  research  Billsburg  was  undergoing  the  process 
of  political  upheaval.  Recent  studies  indicate  that  the  population  base 
was  changing  due  to  a  new  influx  of  professionals,  semi-professionals, 
university  people,  and  Matson  businessmen.  These  newcomers  are  of  a 
more  intellectual  and  liberal  orientation  than  the  older  and  more  con-

interest  in  state  and  national  politics  and  are  involved  in  political-social 
programs  at  the  national  and  even  international  levels.  Thus,  decisions

A  Suggested  Framework  for  Viewing  the  Changing  Rural  Community 

Scientific  American  (September,  1965),  in  discussing  the  alarming 
rate  of  urban  growth  in  America,  directs  our  attention  to  the  creation 
of  the  Megalopolis:  a  concentration  of  linked  urban  centers  that  now 
stretches  from  Boston  to  Washington,  D.  C.  If  "megolopoly"  is  a  poten- 
tial sign  of  America's  future,  let  us  not  ignore  the  growth  of  the  "smaller 
community ."  These  transitional  centers  are  entering  into  dynamic  rela- 
tionships with  their  local  urban  centers;  and  by  this  process,  if  I  may 
introduce  still  another  exotic  terms,  they  are  creating  a  "surbopolis":  a 
concentration  of  linked  communities  about  an  already  developed  urban 
complex. 

Conclusion 

The  anthropologist  in  his  pre-occupation  with  a  "holistic  approach" 
has  been  primarily  concerned  with  the  social-institutional  aspects  of  the 
community,  village,  or  cultural  system,  and  has  neglected  other  possible 
research  perspectives.  If  village  studies  are  to  expand  these  "limits  of 
naivete,"  a  more  sophisticated  approach  along  spatial  dimensions  is 
needed.  While  many  anthropologists  are  clearly  aware  of  the  linkages 
and  flows  across  and  within  systems  and  of  their  significance,  too  few 
studies  have  focused  upon  these  aspects  as  integral  parts  of  their  in- 
vestigations. Today's  communities  no  longer  exist  as  "isolates";  the 
channels  to  other  villages  and  cities  have  become  the  pathways  to  de- 
velopment, and  the  flows  that  pass  along  these  channels  are  a  key  to 
deciphering  the  directions  and  processes  of  change,  and  a  critical  factor 
in  understanding  the  complexities  of  twentieth  century  community  life.

Development  of  a  Modified  Antibody  Plaque  Technique  for  the  Detection 
of  Single  Cells  Making  Anti-viral  Antibody.  B.  H.  Petersen,  Z.  Brahmi, 
J.  S.  Ingraham,  and  A.  S.  Levine,  Indiana  University  Medical  School. — 
Hemolytic  plaque  techniques  detect  the  antibody  produced  by  individual 
antibody-forming  cells  against  various  species  of  red  blood  cells  (rbc), 
or  even  against  haptens  or  proteins  coupled  chemically  to  rbc.  As 
certain  viruses  adsorb  spontaneously  to  rbc  it  was  suggested  that  cells 
making  anti-viral  antibody  might  also  be  detected  by  a  hemolytic  plaque 
technique.  Rabbits  were  given  I.  V.  injections  of  Influenza  virus  strain 
WS-A.  Suspensions  of  spleen  cells  obtained  3  days  after  the  final  injec- 
tion were  examined  for  hemolytic  plaque  formation  against  Chicken  rbc 
and  Pigeon  rbc  coated  with  virus.  These  virus-coated  rbc  spontaneously 
agglutinated  in  our  system.  By  use  of  our  plaque  assay  in  liquid  medium 
(Fed.  Proc.  26,  641,  1967)  it  was  possible  to  observe  both  hemagglutina- 
tion inhibition  and  hemolytic  plaque  formation.  Anti-WS-A  antibody  was 
demonstrated  in  the  serums  by  hemagglutination  inhibition.  Specific 
plaques  were  also  obtained  from  a  rabbit  immunized  with  Influenza  strain 
Lee-B.  These  results  demonstrate  the  feasibility  of  detecting  anti-viral 
antibody  produced  by  single  cells  utilizing  virus-coated  rbc. 

Amber  Streptomycin-resistant  Mutants  of  Escherichia  coli.  Karen  Carl- 
son and  Richard  Bochrath,  Indiana  University  Medical  Center. — A 
specific  genotypic  defect  such  as  the  nonsense  amber  codon  can  cause 
premature  termination  of  protein  synthesis,  at  the  site  of  a  UAG 
codon,  during  translation.  This  defect  may  be  mitigated  by  suppressor 
mutations  which  lead  to  the  synthesis  of  specific  altered  transfer-RNA's. 
Streptomycin-resistant  (Smr)  mutants  of  E.  coli  WWU  were  isolated 
and  characterized.  Some  Smr  mutants  appeared  to  be  amber  streptomy- 
cin-resistant mutants:  they  were  sensitive  to  streptomycin  whenever  cer- 
tain suppressor  mutations  were  introduced.  The  existence  of  these 
mutants  suggests  that  streptomycin  resistance  can  be  conferred  by  an 
incomplete  protein.  Experiments  are  in  progress  to  determine  whether 
this  partial  polypeptide  is  a  ribosomal  protein.

Immune  Response  to  Streptococcus  faecalis  in  the  Rat.  B.  PERI  and  M. 
Wagner,  University  of  Notre  Dame. — Rats  immunized  by  various  meth- 
ods with  a  formalinized  suspension  of  Streptococcus  faecalis  (S.f.)  strain 
ND547  were  compared  for  agglutination  titers  in  serum  and  saliva. 
Low  levels  of  agglutinating  antibody  to  streptococci  are  commonly  found 
in  serum  and  saliva  of  rats  under  the  usual  laboratory  conditions  since 
these  organisms  are  part  of  the  normal  microflora.  Response  to  paren- 
teral immunization  was  studied  in  rats  of  three  categories:  germfree, 
conventional  and  monoassociated  with  5.  faecalis. 

High  serum  titers  were  found  in  all  (S.f.)  monoassociated,  but  non- 
immunized,  rats,  indicating  a  strong  immune  response  to  gastrointestinal 
microflora  alone.  Immunized,  monoassociated  animals  usually  showed 
higher  antibody  levels  than  the  nonimmunized  monoassociates  in  both 
serum  and  saliva,  but  in  some  cases,  high  serum  antibody  level  was  not 
accompanied  by  high  salivary  antibody.  Young  rats  show  more  antibody 
in  saliva  than  in  serum.  It  would  seem  that  salivary  antibody  is  not 
directly  related  to   serum  level. 

Germfree  rats  gave  no  immune  response  to  immunization  procedures 
which  produced  responses  in  both  the  conventional  and  monoassociated 
animals.  In  this  case,  the  germfree  animal,  which  represents  removal  of 
the  antigenic  competition  of  viable  microorganisms,  did  not  show  the 
enhanced  response  anticipated.  This  phenomenon  is  being  investigated 
further. 

Enzymatic  Effect  of  Cobra  Venom  on  Rauscher  Leukemia  Virus  (RLV). 

A.  C.  Raitano  and  A.  S.  Levins,  Indiana  University  School  of  Medicine. 
— The  inactivation  of  RLV  by  Naja  naja  atra  and  Naja  naja  venoms 
was  studied  and  an  attempt  made  to  identify  the  active  virucidal  factors 
in  venom.  Naja  naja  atra  venom  (150,  500,  and  1000  Mg/ml  sodium 
citrate)  was  incubated  with  RLV  at  37° C  for  xk  hour.  The  latter  con- 
centration significantly  decreased  RLV  infectivity.  The  RLV  lipoprotein 
envelope  contains  68%  lecithin.  Cobra  venom  contains  a  potent  phospholi- 
pase  A  (PLA)  that  hydrolyzes  lecithin  to  lysolecithin  and  a  fatty  acid. 
Therefore,  several  characteristics  of  PLA  were  used  to  identify  its  ac- 
tivity against  RLV.  PLA  is  heat  stable  at  100  °C  for  10  minutes  (pH 
5-6).  Naja  naja  venom  (1.5  mg/ml  PBS)  boiled  for  10  minutes  signifi- 
cantly inactivated  RLV.  Naja  naja  venom  containing  inactivated  (boiling 
for  20  minutes)  PLA  did  not  inactivate  RLV.  PLA  is  also  antigenic; 
therefore,  Naja  naja  venom  neutralization  with  specific  antisera  was 
studied.  Naja  naja  venom  (1.0  mg/ml  PBS)  inactivated  RLV  but  neu- 
tralized venom  (1.0  mg/ml  PBS)  did  not.  Thin  layer  chromatograms  of 
venom  on  plasma  phospholipids  showed  inhibition  of  PLA  activity  (leci- 
thin hydrolysis)  by  antisera.  Lysolecithin  (100  Mg/ml  ELO)  itself  was 
also  found  to  inactivate  RLV  while  lecithin  (100  Mg/ml  H20)  did  not. 
The  levels  of  other  venom  enzymes  were  also  examined.  The  results  sug- 
gested PLA  is  an  important  factor  in  RLV  inactivation  by  cobra  venom. 

Suppression  of  Rauscher  virus-induced  Murine  Leukemia  by  L-Aspara- 
ginase.  W.  F.  Campbell  and  A.  S.  Levine,  Indiana  University  Medical 


Bacteriology  111 

Center. — L-asparaginase  from  extracts  of  E.  coli  has  been  demonstrated 
to  cause  regression  of  several  transplantable  murine  leukemias  and 
lymphosarcomas.  The  leukemia  cells,  which  apparently  cannot  synthesize 
L-asparagine,  depend  upon  an  exogenous  supply  of  the  amino  acid.  Nor- 
mal cells  have  high  asparagine  synthetase  activities,  and  do  not  require 
asparagine.  Apparently,  asparaginase  treatment  depletes  the  plasma 
asparagine  level,  and  deprives  the  leukemic  cells  of  their  exogenous 
supply  of  the  amino  acid. 

Investigations  in  our  laboratory  demonstrated  that  asparaginase 
treatment  significantly  suppressed  splenomegaly  in  mice  infected  with 
Rauscher  leukemia  virus  (RLV).  The  enzyme  significantly  increased 
survival  time,  but  did  not  suppress  viremia  of  RLV-infected  mice.  In 
small,  multiple  doses  asparaginase  altered  the  histological  picture  as  seen 
in  spleen  sections,  but  did  not  completely  inhibit  the  leukemic  process. 
In  apparent  contradiction  to  the  asparagine  deprivation  hypothesis,  was 
our  observation  that  asparagine  treatment  suppressed  splenomegaly  and 
prolonged  survival.  The  results  warrant  a  reappraisal  of  the  asparaginase 
mechanism  of  antileukemic  activity  in  RLV-infected  mice. 

Physiological  Studies  of  the  Incorporatsion  of  5-Bromouracil  During 
Growth  and  Sporulation  in  Bacillus  subtilis  -168.  PATRICIA  C.  MORGAN 
and  Robert  F.  Ramaley,  Indiana  University. — Prior  to  an  investigation 
of  DNA  synthesis  and  segregation  during  sporulation,  studies  were  con- 
ducted on  the  physiological  consequences  of  5-bromouracil  (5-BU)  and 
5-bromodeoxyuridine  (5-BUdR)  incorporation  in  a  thymine  requiring 
strain  of  Bacillus  subtilis-168.  The  results  are  summarized  as  follows: 

(1)  The  deoxynucleoside  forms  of  thymine  and  bromouracil  were  in- 
corporated more  rapidly  and  to  a  greater  extent  than  were  the  free  bases. 

(2)  5-bromouracil  incorporation  was  stimulated  by  the  addition  of  a 
small  amount  of  thymine.  This  stimulation  was  also  true  for  the  deoxy- 
nucleosides  of  thymine  and  bromouracil.  (3)  Both  thymidine  and  5- 
bromodeoxyuridine  were  incorporated  when  they  were  both  supplied  to 
growing  cells  at  a  final  ratio  of  BUdR/TdR  +  BUdR  =  0.9.  (4)  Incor- 
poration of  5-BU  or  5-BUdR  for  periods  less  than  that  inducing  thymine- 
less  death  (30-60  minutes)  resulted  in  fully  viable  cells.  (5)  Under  these 
conditions  the  5-BU  incorporated  was  not  selectively  removed  from  the 
cells  upon  resuspension  in  medium  containing  thymine.  This  suggested 
that  the  5-BU  incorporated  was  not  in  false  growing  points  or  "unusual" 
DNA.  (6)  5-BUdR  incorporated  during  late  vegetative  or  very  early 
sporulation  was  included  in  the  developing  spores.  Purified  BU-labeled- 
spores  showed  the  same  viability  as  untreated  spores.  Thus,  conditions 
have  been  obtained  that  allow  the  synthesis  of  apparently  biologically 
active  5-BU  DNA  which  is  incorporated  into  the  developing  spores  and 
does  not  decrease  the  viability  of  the  completed  final  spores. 

Biosynthesis  of  Thiadiketopiperazine  Antibiotics.  D.  R.  Brannon,  M.

aranotin  and  to  determine  the  biosynthetic  relationship  between  the  dif- 
ferent aranotins  and  gliotixin.  Experiments  were  conducted  to  determine 
the  source  of  sulfur  in  the  thiadiketopiperazines  and  the  relationship  be-

Mycophenolic  Acid:  Studies  on  Biological  Activities.  Robert  H.  Wil- 
liams, John  C.  Cline,  Richard  E.  Holmes,  and  Martin  J.  Sweeney, 
Eli  Lilly  and  Company,  Indianapolis.  The  fermentation  broth  of  a  strain 
of  Penicillium  stolonif erum  was  found  to  possess  reproducible  in  vitro 
antiviral  activity.  The  active  component  was  isolated  by  chloroform  ex- 
traction of  filtered  broth  at  pH  3.0  followed  by  column  chromatography 
on  silica  gel  and  crystallization.  Comparison  of  the  physical  properties  of 
the  crystalline  substance  with  those  of  mycophenolic  acid  led  to  its 
identification.  Mycophenolic  acid  is  one  of  the  oldest  known  biologically 
active  mold  metabolites,  first  isolated  by  Gosio  in  1896,  and  since  then 
reported  to  have  weak  antimicrobial  activity.  The  present  study  in- 
cludes some  aspects  concerning  interesting  new  biological  activities  of 
this  compound  recently  discovered  in  our  laboratories,  including  antiviral 
and  antitumor  activity.  Information  concerning  mechanism  of  action 
and  the  effects  on  modification  of  the  basic  structure  to  biological  activity 
will  also  be  presented. 

Genetic  Evidence  for  Resistance  of  Cephalosporium  to  Specific  Compounds. 

Paul  A.  Lemke,  Eli  Lilly  &  Co.,  Indianapolis. — One  hundred  compounds, 
antibiotics,  antimetabolites  and  organic  toxicants,  have  been  surveyed 
for  their  toxicity  to  the  antibiotic-producing  fungus,  Cephalosporium 
acremonium.  This  survey  was  designed  to  obtain  compounds  suitable  as 
selective  agents  for  resistant  mutations  and  of  potential  use  in  the 
detection  of  somatic  recombination  through  homozygosity  of  recessive 
mutations  for  resistance. 

Toxicity  levels  for  several  compounds  were  determined  by  a  gradient- 
plate  method,  and  mutations  for  resistance  to  certain  compounds,  princi- 
pally antimetabolites,  induced.  Selections  for  resistance  were  obtained 
from  among  survivors  of  90%  mortality  after  treatment  with  a  chemical 
mutagen,  nitrosoguanidine.  Resistant  cultures  were  selected  on  gradient 
plates,  and  mutation  frequencies  for  resistances,  spontaneous  as  well  as 
induced,  were  calculated.  Frequencies  for  induced  mutations  for  resist- 
ance to  specific  compounds  varied  but  were  demonstrated  to  be  of  the 
order  of  104  to  10a. 

Among  selections  for  resistance  to  antimetabolites  no  evidence  for 
cross-resistance  has  been  obtained,  and  markers  for  resistance  to  antime- 
tabolites have  proved  to  be  recessive  by  heterokaryotic  tests.  Data  on 
selections  for  resistance  to  other  compounds — specifically,  actidione,  acri- 
flavin,  endomycin,  and  hydroxylamine — were  less  consistent.  Cultures 
selected  as  resistant  to  these  compounds  grew  poorly  even  in  the  absence 
of  toxicant. 


Bacteriology  113 

In  addition  to  the  Cephalosporium  organism  seven  other  fungi 
(Penicillium  chrysogenum,  Emericellopsis  glabra,  Aspergillus  nidulans,  Sac- 
charomyces  cervisiae,  Sistotrema  brinkmanni,  Schizophyllum  commune, 
Coprinus  lagopus)  and  an  actinomycete  (  Actinoplanes  utahensis)  were 
compared  for  sensitivity  to  each  of  the  hundred  compounds.  The 
prokaryotic  nature  of  the  actinomycete  is  implied  by  its  reaction  to 
specific  compounds.  The  fungi  examined  were  heterogeneous  in  response 
to  the  assembled  compounds. 

Effect  of  Oxygen  on  the  Synthesis  of  Nitrate  Reductase  in 
Bacillus  stearothermophilus.  JAMES  H.  NUNER  and  RONALD  J.  DOWNEY, 
Lobund  Laboratory,  University  of  Notre  Dame. — We  are  investigating  the 
biosynthesis  of  the  membrane-bound  electron-transfer  enzyme,  nitrate 
reductase  (NaR).  The  oxygen-repressible  synthesis  of  this  enzyme  in 
resting  cells  has  been  observed  to  begin  shortly  after  the  addition  of 
nitrate.  Cell  division  in  cultures  not  originating  in  nitrate  medium  can 
be  delayed  for  10-12  hours. 

We  have  observed  dramatic  differences  in  the  effect  of  imposing  de- 
repressing  oxygen  tension  (p02)  on  cells  exposed  to  nitrate,  with  and 
without  previous  histories  of  exposure  to  nitrate.  Cells  without  previous 
contact  with  nitrate  die  much  more  rapidly  than  those  exposed  to  the 
same  p02  in  the  absence  of  nitrate.  Cells  with  previous  contact  with  ni- 
trate lose  viability  during  the  first  four  hours  and  then  recover.  Turbidity 
of  such  cultures  does  not  increase  until  recovery  is  complete.  Other  evi- 
dence also  suggests  that  two  populations  of  cells  are  present  in  the  cul- 
ture: one  nitrate-adapted,  capable  of  using  nitrate  as  a  terminal  oxidant, 
and  the  wild  type,  capable  of  using  only  oxygen. 

Oxygen  is  shown  to  permit  growth  of  a  nitrate-adapted  culture  and 
to  promote  the  degradation  of  nitrate  reductase  to  a  basal  level. 

The  effect  of  different  oxygen  tensions  on  the  synthesis  of  nitrate 
reductase  in  an  adapted  population  was  studied.  A  repressing  tension  of 
about  20  mm  Hg  was  found. 

The  Serum  Profiles  of  Certain  Reptile  Sera  and  preliminary  Observations 
on  Antibody  Formation  in  Snakes.  Sylvia  H.  Kendall  and  S.  A.  Min- 
ton,  Indiana  University  Medical  Center. — Serum  samples  from  several 
families  of  snakes,  rock  iguana  (Ctenosaura)  and  rabbit  were  frac- 
tionated by  zone  electrophoresis  (Pevikon)  and  gel  filtration  (Sephadex 
G-200).  Zone  electrophoresis  of  snake  sera  gave  protein  profiles  differ- 
ing from  the  mammalian  pattern  and  showed  variations  among  the  differ- 
ent snake  families.  No  cathodic  protein  was  detected  in  snake  sera  and 
the  largest  peak  was  not  always  the  fast  anode-migrating  one,  charac- 
teristic of  the  mammalian  pattern.  In  addition,  the  electrophoretic  profile 
of  iguana  serum  differed  from  rabbit  serum  and  all  snake  sera.  No  anti- 
genic relationship  between  iguana  and  snake  sera  could  be  shown  by 
capillary  precipitin  tests.  Gel  filtration  of  rabbit  serum  gave  a  profile  of 
three  progressively  larger  peaks.  Two  out  of  three  snake  sera  differed 
in  that  the  first  peak  was  largest  and  the  third  intermediate.  Python 
serum  gave  two  peaks  of  comparable  size  with  a  third  peak  suggested  by 


114  Indiana  Academy  of  Science 

a  shoulder  on  the  last  peak.  Peaks  from  fractionated  snake  sera,  con- 
centrated and  used  in  gel  diffusion  and  Immunoelectrophoresis,  were 
found  to  contain  multiple  components.  Immunoelectrophoresis  of  whole 
snake  sera  resolved  7  to  11  components;  3  to  5  detected  on  the  cathode 
side  of  the  origin.  Immunization  of  fox  snakes  (Elajjhe  vulpina)  with 
bovine  serum  albumin  (Pentex  Fraction  V)  in  Freund's  adjuvant  pro- 
duced no  antibody  response  one  month  after  primary  injection.  Two 
weeks  after  secondary  injection,  snakes  showed  evidence  of  antibody 
response  as  measured  by  agglutination  of  erythrocytes  coupled  to  BSA.

A  Study  of  the  Factors  Controlling  Variation  of  Cuticular  Characters. 
D.  L.  Dilcher  and  C.  A.  Zeck,  Indiana  University. — In  this  study  we 
examined  three  factors  which  we  thought  might  cause  variation  in  the 
cuticular  characteristics  of  leaves.  These  factors  were  leaf  shape,  leaf 
maturity,  and  the  amount  of  sunlight  that  reached  the  leaf.  The  pur- 
pose of  this  study  was  to  help  resolve  some  of  the  controversy  sur- 
rounding the  use  of  cuticular  analysis  as  a  means  of  plant  identification. 
The  species  investigated  for  differing  morphology  was  Quercus  alba, 
White  Oak.  Fagus  grandifolia,  American  Beech,  and  Quercus  rubra, 
Red  Oak,  were  used  for  the  study  of  sunlight  versus  shade  leaves.  Young 
leaves  of  these  trees  were  later  examined  in  order  to  understand  the 
development  of  the  epidermis.  The  cuticular  characteristics  looked  for 
were  the  following:  shape  and  size  of  the  epidermal  cells  and  stomata, 
presence  and  density  of  hairs,  density  of  stomata,  and  pattern  of  the 
accessory  cells.  We  found  that  neither  the  shape  of  the  leaf  nor  the 
position  on  the  leaf  from  which  a  cuticular  sample  was  taken  hindered 
the  identification  of  the  leaf  cuticle.  There  were  slight  variations  ob- 
served, however  the  variations  were  not  severe  enough  to  raise  any 
doubts  as  to  the  species  from  which  the  cuticle  had  been  obtained.  Both 
of  the  species  studied  as  sun  versus  shade  leaves  showed  definite  cuti- 
cular variations.  There  were  many  more  stomata  and  the  cells  of  the 
lower  epidermis  were  much  less  lobed  on  the  leaves  that  grew  in  the 
sunlight.  The  cells  of  the  upper  epidermis  of  the  beech  were  more  lobed 
on  the  shade  leaves  while  the  upper  epidermis  of  the  oak  was  the  same 
in  both  sun  and  shade  leaves.  The  other  cuticular  characters  were  similar 
on  both  sun  and  shade  leaves.  Upon  studying  the  development  of  the 
epidermis  in  young  leaves  it  was  found  that  the  mature  situation  of 
guard  cells  and  stomata  can  be  seen  early  in  the  development  of  a 
leaf  while  the  development  of  the  epidermal  cells  may  follow  different 
paths  as  the  leaves  mature.  (Work  supported  by  NSF  GB5166) 

An  Eocene  Discovery  of  Dendropanax.  G.  E.  Dolph  and  D.  L.  Dilcher, 
Indiana  University. — Leaves  of  Liquidambar,  Sterculia,  Oreopanax,  and 
Artocarpus  were  the  only  lobed  forms  reported  from  the  Wilcox  of 
Tennessee  by  Berry  (1916,  1924,  1930).  In  addition  to  these  forms,  a 
form  similar  to  Dendropanax  (formerly  placed  in  the  form  genus  Aralia 
by  Berry  on  the  basis  of  a  single  specimen  from  Hardy  Mills,  Arks.)  of 
the  Araliaceae  has  been  discovered.  This  form  has  the  following  charac- 
teristics: (1)  three  to  five  lobes;  (2)  shallow  sinuses  between  the  lobes; 
(3)  size  similarity  between  the  main  lobes;  (4)  entire  margin;  (5) 
acuminate  to  ovate  lobes;  (6)  decurrent,  truncate,  or  cordate  base;  (7) 
comptodrome  secondary  venation;  and  (9)  papillate  lower  epidermis  with

randomly  orientated  anisocytic  stomata.  This  form  differs  from  Liquid- 
ambar  which  lacks  an  entire  leaf  margin,  Artocarpus  which  lacks  palm- 
ate venation,  and  Sterculia  which  lacks  anisocytic  stomata  (fossil  forms 
of  Sterculia  have  anomocytic  stomata)  and  reticulate  tertiary  venation. 
The  distinction  between  Oreopanax  and  Dendropanax,  both  members  of 
the  Araliaceae,  would  be  impossible  if  only  the  external  morphological 
features  of  the  leaves  could  be  utilized.  However  a  separation  of  these 
genera  can  be  made  by  a  study  of  the  leaf  cuticle.  The  lobed  forms  of 
Oreopanax  have  paracytic  stomata  while  members  of  the  genus  Dendro- 
panax have  anisocytic  stomata.  Since  the  fossil  form  also  has  anisocytic 
stomata  in  addition  to  the  external  features  associated  with  Dendro- 
panax an  assignment  to  the  genus  Dendropanax  was  possible.  The  as- 
signment of  the  fossil  form  to  a  living  species  of  Dendropanax  cannot  be 
made  due  to  evolution  that  has  taken  place  within  the  genus.  Although 
modern  forms  are  similar  to  the  fossil  in  external  and  stomatal  features, 
most  living  species  differ  in  their  possession  of  sinuous  upper  epidermal 
cells  and  lack  of  papillae  on  the  lower  epidermis.  (This  work  was  sup)

Effects  of  Selenium  on  the  Respiration  of  Excised  Root-tip  Segments  of 
Maize.  Raymond  E.  Girton,  Department  of  Soils  and  Plant  Nutrition, 
University  of  California. — This  study  deals  with  the  effects  of  Na2Se03 
on  the  respiratory  gas  exchange  of  1  cm  root-tip  segments  cut  from  3 
day  germinated  grains.  Phosphate  buffers  were  used  to  maintain  a  pH 
of  4.5  to  5. 

Typical  Q02  values  for  control  (-Se)  root  segments  were  ca  5.6 
ul/hr/mg  dry  wt.  and  5.0  for  Qco2  values.  A  5xl0~6  M  Na2Se03  con- 
centration appeared  to  give  a  3  to  4%  stimulation  in  02  uptake  over 
periods  of  2  hours.  High  concentrations  progressively  decreased  02  up- 
take: 11%  with  10-3  M  Na2Se03  and  30%  with  10-  M.  Carbon  dioxide 
output  was  somewhat  depressed  at  lower  selenite  concentrations.  High 
concentrations  gave  marked  stimulation  averaging  about  30%  above 
the  controls.  Respiratory  quotient  values  here  averaged  1.26  in  contrast 
to  ca  0.9  for  the  controls.  Roots  at  high  selenite  concentrations  turned 
light  yellow  to  brown  during  the  experiments;  those  at  the  lower  con- 
centrations and  the  control  roots  remained  white. 

Oxygen  uptake  by  submerged  roots  in  equilibrium  with  N2  contain- 
ing traces  of  02  was  decreased  to  less  than  1%  of  the  controls,  regard- 
less of  the  presence  or  absence  of  Na2Se03.  Similarly,  the  rate  of  C02 
production  by  selenite-treated  roots  in  equilibrium  with  N2  plus  traces  of 
02  was  of  the  same  magnitude  as  in  the  absence  of  selenite,  viz.  81  and 
83%  of  the  air  controls.  Fermentation/Respiration  ratio  values  averaged 
0.83  in  the  absence  of,  and  0.70  in  the  presence  of  selenite  and  indicated  a 
definite  Pasteur  effect.  The  lower  (+Se)  value  reflects  the  aerobic  stimu- 
lation of  C02  output  by  Na2Se03. 

Time-course  studies  demonstrated  a  gradual  decrease  in  02  uptake 
and  C02  output  rates  for  both  the  control  and  the  104  M  selenite-treated 
roots  in  equilibrium  with  air.   Roots  treated  with  10"  M  selenite  indicated 


Botany  117 

a  modest  immediate  stimulation  in  02  uptake  over  the  controls,  followed 
by  a  steady  decline  to  ca  50%  of  the  initial  value  during  the  3  hours  of 
treatment.  Carbon  dioxide  output  rates  of  the  controls  and  the  10*  M 
Na2Se03  treated  roots  also  declined  with  time.  In  contrast,  the  102  M 
selenite-treated  roots  showed  a  very  strong  immediate  stimulation  in 
C02  output  reaching  an  average  of  153%  of  the  initial  value.  This  was 
followed  by  a  rapid  decline  which  continued  to  the  end  of  the  experiment. 
Respiratory  quotient  values  ranged  from  a  normal  of  ca  0.90  to  a 
maximum  of  1.84  for  the  102  M  Na2Se03  treated  roots.  This  doubling  of 
the  R.Q.  reflects  both  the  stimulation  in  C02  output  and  the  depression  in 
02  uptake  due  to  high  concentrations  of  Na2Se03. 

Some  Disappearing  Plant  Species.  Arthur  T.  Guard,  Purdue  University. 
— While  in  the  very  early  history  of  the  United  States  biologists  were 
very  much  engaged  in  discovering  new  species  of  plants  and  animals,  we 
may  now  be  approaching  an  era  in  which  the  disappearance  of  species 
and  conditions  under  which  they  disappear  will  hold  the  center  of 
attention.  Two  species  that  seem  excellent  subjects  for  this  type  of  study 
are  Franklinia  alatamaha  Marsh,  and  Elliottia  racemosa  Muhl. 

These  two  species  were  first  observed  by  John  and  William  Bartram 
during  their  travels  through  Georgia  about  the  year  1775.  Franklinia 
alatamaha  was  discovered  by  these  two  botanists  in  the  region  of  Fort 
Barrington,  Georgia.  It  is  no  longer  extant  in  nature,  but  has  been 
preserved  as  a  cultivated  ornamental.  The  other  species,  Elliottia  race- 
mosa, is  still  present,  but  it  is  found  in  only  seven  very  limited  areas  in 
Georgia.  Attempts  to  bring  it  into  cultivation  have  been  almost  com- 
pletely unsuccessful. 

In  view  of  the  fact  that  other  sympatric  species  observed  by  the 
Bartrams  in  this  area  are  still  abundant,  the  question  arises  as  to  why 
these  two  species  have  been  almost  completely  unsuccessful. 

Weather  and  Corn  Diseases  in  Indiana  in  1968.  A.  J.  Ullstrup,  Purdue 
University. — Common  corn  smut  caused  by  Ustilago  maydis  (D.  C.) 
Cda.  was  more  prevalent  in  1968  than  in  any  of  the  past  30  years.  In 
June,  6-week-old  seedlings  showed  large  galls  beneath,  or  at,  the  soil 
line.  Such  early  symptoms  haven't  been  reported  in  Indiana  prior  to  this 
year.  Corn  planted  in  late  May  and  early  June  after  excessive  rain  in 
May  showed  neither  the  seedling  galls  nor  the  high  prevalence  of  smut 
infection  on  adult  plants.  The  unusually  cold  weather  in  May  which 
slowed  corn  growth  and  thus  held  the  meristematic  tissues  in  a  vulner- 
able state  for  a  protracted  period  is  believed  responsible  for  the  in- 
creased incidence  of  smut. 

Crazy  top,  a  disease  characterized  by  a  condition  of  phyllody  in  the 
tassel  as  well  as  other  bizarre  symptoms,  was  also  unusually  prevalent  in 
Indiana  this  year.  Corn  planted  in  late  April  and  early  May  was,  in 
many  areas,  subjected  to  heavy  rains  with  consequent  waterlogging  of 
the  soil.  This  condition  is  requisite  for  infection  of  corn  by  the  causal 
agent  Sclerophthora  macrospora  (Sacc.)  Thirum.,  Shaw,  &  Naras.  Corn 
planted  in  late  May  and  early  June  didn't  show  evidence  of  this  disease.

Buggy-whip  or  onion  leaf  is  a  non-infectious  malformation  apparent- 
ly caused  by  excessive  absorption  of  2,  4-D.  This  condition,  while  ob- 
served in  isolated  instances  almost  every  year,  was  widespread  in  much 
of  the  northern  half  of  Indiana.  In  some  fields  the  incidence  reach  90%. 
The  malformation  is  identified  by  the  envelopment  of  upper  portions  of 
the  plant  in  a  tapering  tube  which  often  prevents  tassel  emergence.  The 
predisposing  conditions  leading  to  this  condition  in  corn  are  not  fully 
understood,  but  the  low  temperatures  in  May  are  suspected.  Corn  show- 
ing this  injury  from  over-absorption  of  2,  4-D  often  had  a  high  incidence 
of  smut  infection. 

Induced  Resistance   of    Phaseolus   vulgaris     to   Bean   Anthracnose.  J.   E. 

Rahe  and  J.  Kuc',  Purdue  University. — Etiolated  hypocotyls  of  Phaseo- 
lus vulgaris  respond  hyper  sensitively  to  Helminthosporium  carbonum  or 
Alternaria  sp.  within  24  hr.  after  inoculation.  A  similar  response  occurs 
at  60-72  hr.  after  inoculation  with  a  non-pathogenic  race  of  Colleto- 
trichum  lindemuthianum,  the  causal  agent  of  bean  anthracnose.  Necrotic 
lesions  develop  72-96  hr.  after  inoculation  of  bean  hypocotyls  with  a 
pathogenic  race  of  C.  lindemuthianum.  Induction  of  hypersensitivity  in 
bean  hypocotyls  by  inoculation  with  H.  carbonum,  Alternaria  sp.,  or  a 
non-pathogenic  race  of  C.  lindemuthianum  predisposes  the  inoculated 
tissues  to  resistance  to  a  pathogenic  race  of  C.  lindemuthianum. 

Extracts  of  phenolics  of  hypocotyls  inoculated  with  H.  carbonum, 
Alternaria  sp.,  or  a  non-pathogenic  race  of  C.  lindemuthianum  are  in- 
hibitory to  both  pathogenic  and  non-pathogenic  races  of  anthracnose. 
This  inhibitory  property  appears  6-24  hr.  following  inoculation  with  H. 
carbonum  or  Alternaria  sp.,  and  6-24  hr.  and  again  at  72-120  hr.  after 
inoculation  with  a  non-pathogenic  but  not  a  pathogenic  race  of  C. 
lindemuthianum.  The  production  of  inhibitory  concentrations  of  phenolic 
materials  in  response  to  infection  by  non-pathogenic  races  of  C. 
lindemuthianum  is  suggested  to  account  for  the  varietal  resistance  of 
bean  plants  to  anthracnose. 

Lobelias  of  Franklin  Co.  and  Indiana.  Lloyd  and  Adele  Beesley,  Cedar 
Grove,  Ind. — In  the  Flora  of  Indiana,  Chas.  Deam  states  that  there  are 
six  species  of  Lobelia.  In  searching  for  Franklin  County's  and  Indiana's 
wild  Flowers,  we  have  found  all  six  species:  Lobelia  cardinalis,  L.  siphi- 
litica,  L.  puberula,  L.  kalmii,  L.  inflata  and  L.  spicata.  However,  we 
have  not  found  the  white  flowered  form  of  Lobelia  cardinalis  f.  alba 
which,  according  to  Deam,  has  been  reported  from  the  Dunes  by  Peattie. 
Neither  do  we  have  all  four  well  defined  phases  of  L.  spicata. 

Daily  Variation  in  Chlorophyll  Content  of  Corn  Seedlings.  Karen  Kay 
Curtis  and  David  E.  Smith,  Indiana  State  University. — Two  groups  of 
corn  seedlings  were  grown  for  fourteen  days  under  either  normal  day- 
night  conditions  of  a  greenhouse  or  a  sixteen  hours  light-eight  hours  dark 
cycle  in  a  growth  chamber.  The  chlorophyll  a  and  b  concentrations  of 
the  first  true  foliage  leaf  were  determined  daily.  Determination  was 
based  on  the  specific  absorption  coefficients  of  chlorophyll  a  and  b  in 
80%    (v/v)   acetone.    Although  there  was  a  difference  in  the  degree  of 


Botany  119 

variation  of  the  chlorophyll  concentration  of  the  plants  grown  under  the 
two  conditions,  there  was  a  striking  similarity  in  the  overall  daily  varia- 
tion of  both  chlorophyll  a  and  b.  The  range  of  variation  of  total  chloro- 
phyll content  was  from  a  minimum  of  1.0  mg.  of  chlorophyll/ml.  to  a 
maximum  of  1.8  mg.  of  chlorophyll  /ml.  Plotting  either  the  daily  varia- 
tions of  chlorophyll  a  and  b  or  total  chlorophyll  content  resulted  in 
graphs  with  maxima  at  4,  8,  and  12  days  and  minima  at  3,  6,  and  10 
days.  The  minima  were  shown  to  be  significantly  related  statistically  to 
the  number  of  leaves  unfurled  at  the  1%   level.

Pennsylvanian  Coal  Ball  Flora  of  Indiana 

Robert  W.  Judd  and  Jerry  J.  Nisbet,  Bethany  Nazarene  College, 
Bethany,  Oklahoma,  and  Ball  State  University,  Muncie,  Indiana. 

Abstract 

This  study  was  undertaken  to  further  the  understanding-  of  the  flora 
of  Indiana  of  the  Pennsylvanian  Period.  While  other  workers  have  studied 
compression  fossils  of  Indiana  from  the  Pennsylvanian  Period,  the  present 
study  represents  the  first  comprehensive  work  on  coal  ball  plants.  Coal 
balls  are  specialized  calcium  carbonate  concretions  which  are  sometimes 
found  in  coal  seams.  These  concretions  usually  contain  well-preserved 
petrified  plant  remains. 

Utilizing-  the  "peel  technique,"  detailed  analysis  is  made  of  selected 
coal  balls  which  were  collected  in  southwestern  Indiana.  The  plants,  or 
plant  parts,  are  classified  to  genus,  using  the  system  proposed  by  An- 
drews.   Five   divisions   are   represented,   including  a   total   of   27   genera. 

The  Pennsylvanian  plant  assemblage  of  Indiana,  based  on  the  present 
study,  is  compared  to  the  Pennsylvanian  plant  assemblage  of  Illinois. 
Only  minor  differences  in  the  represented  genera  appear,  which  suggests 
that  a  relatively  uniform  flora  may  have  existed  over  portions  of  Indiana 
and  Illinois  during  that  Period. 

Methods  and  Materials 

During  1966  and  1967,  collecting  trips  were  made  to  the  coal  mining 
regions  of  Indiana.  Most  of  the  collecting  was  done  during  the  summer 
of  1967  after  analysis  and  sampling  had  revealed  the  most  profitable 
collecting  areas. 

Coal  balls  used  in  the  present  study  were  collected  from  eight  sites

in    southern   Indiana    and    the   best    specimens    were   then    selected    for 
intensive  study.    Table  1  shows  the  location  of  each  collecting  site. 

The  coal  balls  were  prepared  for  study  by  first  cutting  them  into 
uniform  slabs  about  %  inch  in  thickness.  The  cutting  was  done  on  an 
18-inch  Highland  Park  mechanically-fed  diamond  saw.  Following  the 
cutting  process,  the  slabs  were  washed  in  detergent  to  remove  the  cool- 
ant. After  drying,  the  material  was  prepared  for  study  by  using  the 
peel  technique. 

With  this  technique  the  slabs  were  first  etched  in  a  dilute  (5-10%) 
solution  of  hydrochloric  acid  and  allowed  to  air  dry.  The  etched  surface 
was  then  flooded  with  acetone,  and  a  sheet  of  cellulose  acetate  film 
(.005")  was  immediately  placed  on  the  wet  surface.  By  rapidly  rolling 
the  acetate  film  onto  the  slab,  nearly  all  air  bubbles  were  eliminated. 
For  routine  operations  the  slabs  were  then  allowed  to  air  dry  for  twenty 
to  twenty-five  minutes.  When  dry,  the  film  was  peeled  from  each  slab. 
The  organic  material  of  the  preserved  plants  which  adhered  to  the  film 
provided  the  thin  layer  of  plant  material  necessary  for  microscopic 
examination. 

The  materials  were  cataloged  and  the  acetate  peels  were 
examined  under  a  20X  binocular  microscope.  Desired  portions  were  cut 
from  the  peels,  cleared  in  xylene,  and  mounted  in  Kleermount  on  micro- 
scope slides.  The  microscope  slides  prepared  by  this  procedure  were 
carefully  analyzed  and  served  as  the  source  of  data  for  the  present  study. 
The  coal  balls,  acetate  peels,  and  microscope  slides  were  then  stored  as 
a  reference  collection  at  Ball  State  University. 

Discussion 

The  classification  system  used  in  the  present  study  is  the  system 
established  by  Andrews  (1).  Five  divisions  of  plants  are  represented  in 
the  present  study. 

Lycopodophyta 

The  lycopods  of  the  past  were  a  rich  and  varied  group  which  exhibited 
far  greater  dominance  than  do  the  modern  forms.  Whereas  the  existing 
lycopods  are  mostly  creeping  or  herbaceous  forms,  many  extinct  members 
of  this  group  attained  tree  size  and  developed  complex  reproductive 
structures  approaching  the  seed  habit.  The  two  dominant  families  are 
the  Lepododendraceae  and  Sigilliariaceae.  All  lycopod  material  in  the 
present  collection  is  placed  in  the  Lepidodendraceae,  although  other 
workers  might  place  some  of  the  specimens  in  the  Sigillariaceae  because 
of  the  great  similarity  which  exists  between  the  organs  of  the  two 
families. 

Probably  the  genus  most  frequently  encountered  by  researchers  is 
Lepidodendron.  This  genus  includes  many  species.  Even  though  all 
these  organs  have  never  been  correlated  for  a  single  species,  the  genus 
Lepidodendron   is   very  well   understood. 


122  Indiana  Academy  of  Science 

The  leaves  of  Lepidodendron  are  long  and  grass-like  and  vary  a 
great  deal  in  size  from  one  plant  to  the  next.  As  the  leaves  fell  from 
the  stem  they  left  a  characteristic  scar  which  persisted  even  on  very  old 
trunks.  The  cones  are  basically  similar  to  those  of  living  lycopods,  but 
larger. 

The  anatomy  of  the  stem  of  Lepidodendron  is  rather  complex.  Noth- 
ing comparable  to  secondary  phloem  was  produced  in  the  steles.  Sur- 
rounding the  stele  is  an  extensive  cortex  that  was  the  site  of  abundant 
periderm  formation  as  the  tree  matured.  This  periderm,  unlike  the  cork 
of  modern  trees,  remained  alive  and  meristematic.  As  it  became  thicker, 
splits  developed  in  the  surface  and  eventually  the  outer  portions  of 
periderm  were  sloughed  off.  Since  the  stele  of  the  stem  never  attained 
great  size,  the  large  diameter  of  some  trunks  was  due  mainly  to  the  large 
periderm  region. 

In  material  from  the  present  collection,  the  stem  of  Lepidodendron 
is  represented  by  one  nearly  entire  stem  specimen  and  several  stele  frag- 
ments. The  nearly  entire  stem  (Figure  1)  illustrates  the  exarch 
protostelic  nature  of  the  genus,  but  exhibits  very  little  of  the  periderm 
region.  In  another  specimen  some  traces  of  the  periderm  region  are 
found  in  association  with  what  is  believed  to  be  a  leaf  base. 

The  underground  portions  of  Lepidodendron  are  placed  in  the  genus 
Stigmaria.  Two  closely  spaced  dichotomies  occurred  at  the  base  of  the 
trunk  resulting  in  the  formation  of  four  main  rhizomes.  The  small  roots 
which  arise  from  the  ultimate  branches  of  the  rhizopore  are  protostelic. 
The  small  vascular  trace  of  the  root  is  composed  of  8-10  tracheids,  and  is 
surrounded  by  three  distinct  regions  of  cortex.  In  the  distal  portion  of 
the  root,  the  middle  cortex  is  not  found,  having  presumably  undergone 
natural  disintegration.  The  vascular  trace  and  small  inner  cortex  are 
then  found  somewhat  eccentrically  suspended  by  small  remnants  of 
cortical  tissue  called  trabeculae. 

The  present  collection  contains  many  specimens  of  Stigmaria  roots. 
Several  specimens  have  been  isolated  which  exhibit  the  three  distinctive 
cortex  regions  and  are  thus  believed  to  be  sections  from  near  the 
rhizophore.  Another  section  (Figure  2)  shows  the  characteristic  arrange- 
ment of  tissues  which  results  when  the  middle  cortex  disintegrates  and 
the  vascular  tissue  is  displaced. 

Although  the  size  of  the  leaves  varies  from  species  to  species,  and 
even  on  the  same  plant,  they  remain  similar  in  structure.  The  leaves  are 
long  and  linear,  with  a  prominent  midrib  projecting  on  the  abaxial  sur- 
face. The  single,  centrally-located  vascular  bundle  is  composed  of  a 
group  of  tracheids  surrounded  by  thin-walled  cells  which  probably  repre- 
sent phloem  tissue.  The  blade  of  the  leaf  contains  rather  extensive  thick- 
walled  hypodermal  cells  under  both  the  upper  and  lower  epidermis, 
between  which  is  found  a  loosely  arranged  photosynthetic  tissue. 

The  previously  indicated  widespread  occurrence  of  Lepidodendron  in 
Indiana  is  further  substantiated  by  the  great  number  of  Lepidophylloides

bundle  and  sheath  quite  well  (Figure  3),  but  no  leaves  were  found  with 
sufficient  internal  preservation  to  illustrate  phloem  tissue.  This  specimen 
also  shows  the  hypodermal  regions  and  portions  of  the  spongy  mesophyll. 
All  specimens  found  illustrate  the  prominent  midrib  on  the  abaxial 
surface  of  the  leaf. 

Many  species  of  cones  have  been  described  which  are  borne  on 
Lepidodendron;  most  of  these  have  been  assigned  to  the  genus 
Lepidostrobus.  These  cones  vary  in  size  over  a  considerable  range,  with 
specimens  averaging  13  mm.  in  diameter  and  15  cm.  in  length  commonly 
found.  Some  exceedingly  large  specimens  8  cm.  in  diameter  and  over 
30  cm.  long  are  occasionally  encountered.  The  cones  are  borne  terminally, 
with  the  sporophylls  spirally  arranged  about  a  central  axis.  Nearly  all 
the  cones  found  have  been  heterosporous,  with  both  unisexual  and  disexual 
cones  found.  The  sporangia,  borne  on  the  adaxial  surface  of  the 
sporophyll,  are  elongate  and  nearly  circulate  in  cross  section.  The  distal 
portion  of  the  sporophyll,  called  the  lamins,  is  upturned  and  overlaps 
the  sporophylls  above,  forming  a  protective  outer  covering. 

Portions  of  the  cone  axis  and  sporophylls  are  found  only  occasionally 
in  the  present  material,  which  would  perhaps  indicate  that  the  cones 
were  not  so  widely  distributed  as  the  other  organs  of  this  plant.  The 
cross  section  of  one  cone  shows  the  sporophylls  grouped  about  the  axis 
in  an  orderly  arrangement.  In  another  specimen  (Figure  4)  the  vascular 
tissue  of  the  axis  is  shown  and  some  of  the  sporangia  may  be  observed  to 
be  filled  with  microspores. 

While  many  cones  of  Lepidodendron  contain  a  large  number  of 
spores  in  each  sporangium,  others  contain  as  few  as  four.  The  genus 
Lepidocarpon,  established  by  D.  H.  Scott  in  1901,  has  only  one  functional 
megaspore  in  each  megasporangium,  although  three  aborted  megaspores 
are  associated  with  the  functional  one.  When  mature,  two  lateral  alations 
of  the  sporophyll  grow  upward  to  almost  completely  envelop  the 
sporangium,  leaving  only  a  slit-like  opening  at  the  top.  The  resulting 
structure  is  a  seed  in  the  sense  that  it  is  an  integumented  mega- 
sporangium with  a  slit-like  opening  in  the  top,  analogous  to  the  micropyle 
of  a  modern  seed. 

Lepidocarpon  "seeds"  are  very  abundant  in  the  present  material. 
Although  clusters  of  the  "seeds"  are  found,  they  are  not  found  in 
organic  contact  with  each  other  or  with  any  other  organ.  Many  of  the 
present  specimens  show  the  enveloping  alations  and  slit-like  opening  at 
the  top  (Figure  5).  In  some  longitudinal  sections  of  the  "seeds"  the 
sporangial  walls  can  be  seen  distinctly  separate  from  the  sporophyll 
alations. 

Coniferophyta 

The  division  Coniferophyta  contains  two  orders,  the  Cordaitales  and 
Coniferales.  The  former  was  a  dominant  group  of  Pennsylvanian  seed 
plants  from  which  the  Coniferales  are  believed  to  have  evolved.    Rapid

evolution  and  diversification  of  the  Conife rales  apparently  occurred  during 
the  Permian  Period.  Some  of  the  modern  coniferous  trees  have  changed 
little  from  their  Permian  ancestors. 

Members  of  the  Corditales  were  large  trees,  often  seventy-five  to 
one  hundred  feet  in  height,  with  a  crown  of  large,  strap-shaped  leaves. 
Although  Cordaites  is  the  name  proposed  first  for  the  leaves  of  the  tree, 
researchers  include  more  of  the  plant  organs  within  the  genus  Cordaites 
as  the  affinities  of  the  organs  become  known. 

The  stem  of  Cordaites  contains  a  chambered  or  septate  pith  which 
is  made  up  of  closely  spaced  plates  of  parenchymatous  pith  separated  by 
air  spaces.  This  distinctive  and  characteristic  pith  is  very  similar  to  that 
found  in  the  modern  genus  Juglans.  Outside  the  xylem  the  stem  pro- 
duced a  narrow  band  of  cortical  tissue,  encircled  by  a  zone  of  periderm. 

The  Cordaites  leaf  is  superficially  very  similar  to  a  modern  Iris 
leaf  except  in  size.  Specimens  of  the  leaves  have  been  found  which 
attained  a  length  of  one  meter  and  a  width  of  nearly  15  cm.  The  veins 
of  the  leaf  are  dichotomously  branched,  but  the  veins  ascend  so  steeply 
that  the  venation  pattern  appears  to  be  parallel.  The  structure  of  the 
individual  bundles  is  identical  to  that  of  the  vascular  bundles  in  modern 
cycads.  In  some  specimens  of  Cordaites  leaves  the  mesophyll  is  undif- 
ferentiated, while  in  others  the  mesophyll  is  arranged  into  a  palisade-like 
upper  region  and  a  more  loosely  arranged  lower  region.  The  overall 
structure  suggests  a  tough  and  stress  resistant  leaf. 

Cordaites  leaves  are  quite  abundant  in  the  present  collection,  sug- 
gesting that  Cordaites  must  have  been  one  of  the  prominent  plants  of 
the  Pennsylvanian  swamps  in  Indiana.  Most  of  the  leaf  specimens  in 
the  present  material  display  relatively  poor  internal  preservation.  Figure 
6  shows  a  typical  Cordaites  leaf  in  cross  section.  The  vascular  bundles 
with  their  hypodermal  "ribs"  are  well  illustrated  in  this  specimen.  The 
evenly  spaced  vascular  bundles  indicate  the  nearly  parallel  venation 
pattern. 

The  reproductive  structures  of  Cordaites  are  assigned  to  the  genus 
Cordaianthus.  The  phrase  "dwarf  shoot"  is  accurately  applied  to  these 
reproductive  structures  to  distinguish  them  from  the  cones  of  modern 
conifers.  Each  shoot  is  4-6  mm.  long  and  is  made  up  of  twenty  to  thirty 
closely  inserted  scales  which  are  spirally  arranged  around  the  central 
axis.  The  most  distal  scales  of  the  microsporangia  dwarf  shoot  are 
fertile,  each  bearing  about  six  sporangia.  In  the  megasporangiate  shoot 
only  one  fertile  scale  is  found,  bearing  a  single  ovule,  which  is  generally 
hidden  by  the  overlapping  sterile  scales.  It  is  readily  apparent  that 
Cordaianthus  bears  little  resemblance  to  the  cones  of  modern  conifers. 

Cordaianthus  is  represented  sparingly  in  the  present  collection.  A 
single  specimen  illustrates  a  tangential  section  of  Cordaianthus  which 
shows  the  sterile  scales,  but  no  fertile  ones. 

Most  of  the  isolated  seeds  attributed  to  Cordaites  are  assigned  to  the 
genus    Cardiocarpus.     Nearly   all   the    seeds    of   the    Pennsylvanian   age

which  exhibit  bilateral  symmetry  in  cross  section  are  arbitrarily  placed 
within  this  genus. 

Several  good  specimens  of  Cardiocarpus  are  represented  in  the  pres- 
ent collection.  Figure  7  shows  a  longitudinal  section  of  Cardiocarpus 
spinatus,  illustrating  the  projections  of  the  sclerotesta  and  traces  of  the 
nucellus. 

Arthrophyta 

A  burst  of  evolution  in  the  Arthrophyta  division  during  the  Pennsyl- 
vanian  Period  produced  some  of  the  most  unique  plants  that  have  ever 
lived.  The  great  columnar  trunks  of  Calamites  with  their  whorles  of 
branches,  perhaps  resembling  a  giant-size  Equisetum,  surely  must  have 
been  a  striking  feature  of  the  Pennsylvanian  landscape.  While  Arthro- 
phyta is  a  very  diverse  division,  certain  characteristics  tend  to  bind  its 
members  together  as  a  unit.  The  chief  characteristics  of  the  arthrophytes 
are  their  ribbed  and  jointed  stems,  and  the  whorled  arrangement  of  the 
leaves  and  sporangia-bearing  organs.  A  rapid  decline  in  the  number  and 
variety  of  arthrophytes  apparently  began  during  the  Permian  Period, 
and  only  a  single  genus,  Equisetum,  survives  today. 

The  two  major  orders  of  Arthrophyta  are  Sphenophyllales  and 
Equisetales.  The  latter  is  made  up  of  two  families,  the  Equisetaceae 
containing  the  fossil   representative. 

The  family  Calamitaceae  contains  the  arborescent  arthrophytes.  The 
largest  members  of  this  family  were  trees  well  over  fifty  feet  in  height. 
While  the  isolated  organs  of  the  members  of  this  family  are  assigned 
generic  and  specific  names,  the  organs  are  believed  to  belong,  for  the 
most  part,  to  a  single,  well  denned  plant  named  Calamites. 

The  stem  structure  of  Calamites  is  generally  similar  to  that  of 
modern  Equisetum.  The  larger  stems  have  a  pith  cavity  and  strongly 
developed  secondary  wood.  Arthropitys,  the  most  frequently  encountered 
stem  genus,  exhibits  secondary  wood  which  is  divided  into  sectors  by 
rays  only  one  or  two  cells  wide.  In  Calamodendron,  the  rays  are  bordered 
by  vertically  aligned  fiber  cells.  In  the  third  genus,  Arthroxylon,  fibers 
are  densely  interspersed  within  the  rays. 

One  fairly  complete  stem  specimen  of  Calamites  is  represented  in 
the  present  collection  which  illustrates  the  pith  and  secondary  wood  in 
somewhat  crushed  condition.  Many  isolated  wood  fragments  are  char- 
acteristically found  in  coal  ball  petrifactions,  and  analysis  of  some  frag- 
ments in  the  present  collection  have  shown  them  to  represent  Arthro- 
pitys. Other  fragmentary  wood  specimens  from  the  present  collection 
indicate  the  possibility  of  the  presence  of  additional  wood  genera. 

The  anatomy  of  Calamites  roots,  assigned  to  the  genus  Asteromyelon, 
is  different  from  that  of  the  stem.  The  roots  lack  the  jointed  feature  of 
the  stem,  and  a  well  preserved  pith  is  usually  present.  The  cortex  is 
rarely  preserved  in  the  roots,  but  when  present,  large  cavities  similar 
to  the  canals  found  in  the  cortex  of  Equisetum  are  observed. 


128  Indiana  Academy  of  Science 

Several  sections  from  the  present  collection  illustrate  internal 
anatomy  which  is  characteristic  of  Aster omyelon.  The  cortex  is  not  pres- 
ent in  any  of  the  present  sections,  making  positive  identification  difficult. 
The  large  well  preserved  pith  and  typical  wood  development  are  evident 
in  several  specimens.  On  the  basis  of  the  pith  and  wood  features,  the 
present  specimens  are  assigned  to  Aster  omyelon.  In  some  of  the  sections 
(Figure  8)  a  branch  root  can  be  seen  emerging  from  the  main  root.  The 
relative  scarcity  of  specimens  from  this  genus  seems  to  indicate  that  the 
roots  are  not  widely  distributed  in  Indiana. 

Cones  which  are  believed  to  have  calamitean  affinities  vary  a  great 
deal;  however,  all  have  the  characteristic  whorled  arrangement  of 
sporangiophytes.  Calamostachys,  the  most  common  petrified  genus,  has 
suggestive  whorles  of  sporangiophores  alternating  with  whorles  of 
sterile  bracts.  The  sporangiophores  are  pelate  (as  in  modern  Equisetum) 
with  the  sporangia  oriented  toward  the  cone  axis. 

In  the  present  collection,  specimens  of  Catamites  cones  are  found  in 
small  numbers  and  are  poorly  preserved.  The  author  found  one  speci- 
men believed  to  be  a  sporangiophore  with  fragments  of  the  pelate 
sporangiophore.  Based  on  this  evidence,  the  specimen  is  assigned  to 
Calamostachys.  The  lack  of  additional  material  suggests  a  rather  sparse 
distribution  of  the  cones  of  Catamites  in  Indiana. 

The  order  Sphenophyllales  contains  only  one  genus,  Sphenophyllum, 
although  several  other  generic  names  are  applied  to  the  cones  of  this 
plant.  The  growth  habit  has  been  variously  interpreted  as  aquatic, 
creeping  or  climbing;  and  erect,  terrestrial  and  self-supporting.  The 
leaves  of  Sphenophyllum  were  borne  in  whorles  at  the  nodes  of  a 
slender,  ribbed,  and  jointed  stem.  Each  leaf  was  somewhat  wedge-shaped 
and  attached  to  the  stem  at  the  narrow  end.  The  broad  end  of  the  leaf 
was  variously  cleft  or  notched.  The  leaves  were  nacrophyllous,  with 
from  three  to  many  vascular  bundles  in  each  leaf.  While  nearly  all 
knowledge  about  the  leaves  of  Sphenophyllum,  has  been  derived  from  the 
study  of  coal  balls. 

The  stem  of  Sphenophyllum  is  protostelic,  and  the  wood  is  unlike 
that  found  in  any  other  plant.  The  center  of  the  stem  contains  a  tri- 
angular group  of  primary  tracheids  with  small  protoxylem  cells  located 
at  the  apices  of  the  primary  wood.  In  older  stems  a  considerable  amount 
of  secondary  wood  is  found.  The  tracheids  of  the  secondary  xylem 
which  are  located  outside  the  apices  of  primary  wood,  are  smaller  than 
the  remaining  tracheids  of  the  secondary  wood.  Some  specimens  have 
been  found  with  a  cortex  of  thin-walled  cells,  but  the  cortical  tissue  is 
not  generally  preserved. 

A  fairly  widespread  distribution  of  Sphenophyllum  during  the  Penn- 
sylvanian  times  is  suggested  by  the  many  good  preservations  of  the 
stele  region  of  the  stems  in  the  present  collection.  Figure  9  illustrates 
the  triarch  protostele  which  characterizes  the  stem  of  Sphenophyllum. 
The  structure  of  the  secondary  wood  may  easily  be  seen,  and  the  smaller

tracheids  outside  the  protoxylem  are  clearly  evident.    This  section  also 
illustrates  the  small  ray  cells  among  the  tracheids  of  the  secondary  wood. 

The  roots  of  Sphenophyllum  lack  the  ribbed  and  jointed  features  of 
the  stem.  The  internal  anatomy  of  the  root  is  similar  to  that  of  the 
stem,  except  that  the  protostele  is  diarch  instead  of  triarch. 

Several  specimens  of  Sphenophyllum  roots  are  represented  in  the 
present  collection,  although  they  are  not  encountered  so  frequently  as 
specimens  of  the  stem.  The  diarch  protostele  of  the  root  is  clearly  evident 
in  one  specimen  and  the  secondary  wood  appears  similar  to  that  of  the 
stem.    The  cortex  region  is  also  shown  in  the  specimen. 

Pteridospermophyta 

The  plants  in  this  division  exhibit  a  combination  of  two  character- 
istics which  are  unique  and  quite  interesting.  The  plants  possess  fern 
foliage  and  bear  small  nut-like  seeds.  The  combination  of  these  two 
characteristics  gives  rise  to  the  name  Pteridospermophyta  or  seed  ferns. 
While  joined  by  these  two  unifying  characters,  the  seed  ferns  were  in 
other  ways  quite  diverse  and  were  widespread  in  the  swampy  regions 
during  the  Pennsylvanian  Period. 

Two  classes  of  pteridosperms  are  recognized,  the  Lynginopteridaceae 
and  the  Medullosaceae.  One  member  of  the  Lynginopteridaceae  is 
Callistophyton.  The  stem  of  this  plant  contains  a  large  pith  region  of 
very  thin-walled  cells.  Remnants  of  the  primary  xylem  tissue  can  often 
be  observed  at  the  periphery  of  the  pith,  followed  by  a  broad  zone  of 
secondary  wood.  A  considerable  amount  of  secondary  phloem  was  pro- 
duced outside  the  xylem,  but  this  tissue  is  seldom  preserved.  Periderm 
was  probably  produced  on  the  outside  of  the  stem,  but  little  positive 
evidence  has  been  advanced  to  support  this  idea. 

The  stem  of  Callistophyton  is  represented  by  a  single  specimen  in 
the  present  collection.  The  large  pith  region  is  obvious  (Figure  10),  and 
traces  of  primary  xylem  may  be  observed  at  some  points  around  the 
periphery  of  the  pith.  The  well  developed  zone  of  secondary  wood  with 
its  narrow  rays  can  also  be  seen  in  this  specimen. 

The  class  Lygihopteridaceae  contains  a  variety  of  seeds.  Physostoma 
is  a  small  seed,  about  6  mm.  long  and  2.5  mm.  in  diameter.  The  cup- 
shaped  pollen  chamber  is  very  distinctive,  and  may  contain  a  large 
number  of  pollen  grains.  The  integument  of  the  seed  is  fused  with  the 
nucellus  except  at  the  apex.  At  the  apical  end  the  integument  is  extended 
beyond  the  body  of  the  seed  into  ten  to  twelve  projections.  The  outer 
region  of  the  integument  is  composed  of  brick-shaped  cells  arranged 
radially,  while  the  inner  region  is  composed  of  longitudinally  arranged 
cells.  Large  unicellular  hairs  are  sometimes  found  attached  to  the  out- 
side of  the  integument.  Conostoma  is  the  genus  of  a  similar,  but  slightly 
smaller  seed  than  Physostoma.  The  structure  of  the  integument  is 
fused  with  the  nucellus  except  at  the  apex.  No  projections  of  the 
integument  are  present  in  Conostoma. 


Botany  131 

Many  seeds  are  represented  in  the  present  collection  which  are  prob- 
ably assignable  to  the  Lyginopteridaceae.  Considerable  difficulty  was 
encountered  in  attempts  to  identify  these  seeds.  The  general  literature 
does  not  provide  adequate  information  to  permit  separation  of  genera  of 
seeds,  particularly  if  the  entire  specimen  is  not  present.  For  this  reason, 
the  classification  of  the  two  genera  below  is  tentative. 

Both  Physostoma  and  Conostoma  are  represented  in  the  present  col- 
lection. Figure  11  shows  a  longitudinal  section  of  Physostoma  which  illus- 
trates the  arrangement  of  cells  in  the  integument.  The  distinctive  pollen 
chamber  and  the  projections  of  the  integument  are  not  shown  because 
a  suitable  section  could  not  be  made.  Conostoma  seen  in  cross  section 
illustrates  the  typical  ovoid  shape.  Remains  of  the  nucellus  may  be 
observed   in  this   specimen. 

The  family  Medullosaceae  is  identified  chiefly  by  the  presence  of  a 
polystelic  vascular  system  in  the  stem.  Nearly  all  members  of  this  fam- 
ily are  assigned  to  Medullosa  which  is  evidently  a  genus  of  very  broad 
limits.  The  foliage  borne  on  the  stem  was  of  the  Alethopteris  or 
Neuropteris  type  and,  when  seen  in  cross  section,  the  large  petioles  of 
the  fronds  bear  a  considerable  resemblance  to  the  stem  of  modern  Zca. 
The  seeds  associated  with  Medullosa  are  larger  than  those  of  the 
Lyginopteridaceae. 

The  stem  of  Medullosa  contains  from  3-27  small  oval  protosteles 
surrounded  by  a  broad  region  of  cortical  tissue.  The  stem  itself  repre- 
sented only  a  small  part  of  the  total  size  of  the  Medullosa  trunk.  The 
enveloping  petiole  bases  account  for  most  of  the  diameter  of  the  large 
trunk. 

Isolated  petiole  bases  are  frequently  represented  in  coal  balls,  and 
are  assigned  to  the  genus  Myeloxylon.  The  petioles  are  quite  large,  com- 
monly 4  cm.  or  more  in  diameter  where  they  grow  free  from  the  stem. 
Myeloxylon  contains  many  vascular  bundles  scattered  through  a  zone 
of  thin-walled  pith  cells.  The  bundles,  derived  from  repeated  divisions 
of  the  main  leaf  traces  consist  of  several  xylem  elements  surrounded  by 
a  bundle  sheath.  Phloem  tissue  is  not  usually  preserved  in  the  bundles. 
The  outer  region  of  the  petiole  consists  of  a  hypodermal  zone  of  thick- 
walled  fibrous  strands,  among  which  secretory  canals  may  occasionally 
be  observed  to  occur. 

Myeloxylon  is  represented  frequently  in  the  present  collection.  The 
hypodermal  zone  and  scattered  arrangement  of  the  vascular  bundles 
can  be  seen  in  several  specimens.  The  overall  resemblance  of  Myeloxylon 
to  the  stem  of  Zea  is  evident. 

The  foliage  of  Medullosa  is  of  the  Alethopteris  or  Neuropteris  type. 
The  differences  between  these  genera,  established  mainly  on  the  basis 
of  compression  fossils,  are  mainly  differences  in  the  venation  pattern  and 
the  mode  of  attachment  of  the  leaflets  to  the  rachis.  In  cross  section,  the 
two  genera  are  quite  similar  except  that  the  midrib  of  Alethopteris  is 
more  prominent  than  that  of  Neuropteris. 


132  Indiana  Academy  of  Science 

As  seen  in  cross  section,  Alethopteris  leaves  are  revolute  or  curled 
at  the  margins.  The  parenchymatous  mesophyll  is  palisade-like  in  the 
upper  region  and  more  loosely  arranged  in  the  lower  portion  of  the  leaf. 
The  midrib  is  very  prominent  on  the  abaxial  surface,  and  the  main  vas- 
cular bundle  it  contains  shows  the  same  structure  as  the  bundles  in  the 
Myeloxylon  petiole.  The  secondary  vascular  bundles  exhibit  the  same 
tissue  arrangement  as  the  main  bundle,  but  have  some  fibers  associated 
with  the  xylem  cells. 

Two  genera  of  seeds  are  normally  found  in  association  with 
Alethopteris  and  Medullosa.  Pachytesta  seeds  are  quite  large,  some 
reaching  a  length  of  6  cm.  or  more.  The  seed  is  more  or  less  circular  in 
median  cross  section  and  becomes  somewhat  triangular  toward  the 
micropylar  end.  In  overall  general  appearance,  Pachytesta  resembles  a 
pecan  seed. 

Two  specimens  of  Pachytesta  are  represented  in  the  present  collec- 
tion. One  specimen,  representing  a  small  variety  of  seed,  clearly  illus- 
trates the  structure  of  the  integument.  The  nucellus  of  this  specimen  is 
free  from  the  integument,  and  the  conspicuous  ribs  of  the  integument 
are  also  evident.  The  second  specimen,  representing  a  much  larger 
variety,  was  found  partially  exposed  at  the  surface  of  a  weathered  coal 
ball.  The  seed  was  nearly  complete,  including  the  integument,  and  was 
5  cm.  long  and  about  2.5  cm.  in  diameter.  Although  the  external  preser- 
vation of  the  seed  was  good,  examination  revealed  little  internal 
preservation. 

Stephanospermum  is  another  well-known  seed  believed  to  be  borne 
on  Medullosa.  Seeds  of  this  genus  are  comparatively  small,  usually 
about  10  mm.  long  and  5  mm.  in  diameter.  The  most  striking  feature  of 
Stephanospermum  is  the  presence  of  a  well-developed  collar  of  the 
sclerotesta  around  the  micropylar  region.  The  apex  of  the  pollen  chamber 
extends  well  beyond  the  body  of  the  seed. 

Several  specimens  of  Stephanospermum  are  represented  in  the 
present  collection.  None  of  the  specimens  could  be  cut  in  such  a  way  as 
to  reveal  the  distinctive  collar  of  the  sclerotesta.  In  cross  section,  some 
of  the  integument  structure  can  be  observed,  although  the  outer  fleshy 
layer  is  not  preserved  in  these  specimens.  The  remains  of  the  nucellus 
may  be  seen  as  a  thin  band  around  the  inside  of  the  seed. 

The  microsporangiate  organs  of  Medullosa  are  assigned  to 
Dolerotheca.  This  is  a  complex  organ,  consisting  of  many  tubular  micro- 
sporangia  imbedded  in  a  cellular  matrix.  In  overall  appearance, 
Dolerotheca  probably  resembled  a  small  wasp's  nest,  about  4  cm.  in 
diameter  and  20  mm.  thick.  When  mature,  this  organ  produced  huge 
ovoid  microspores,  approximately  .4  mm.  long.  Several  fragments, 
believed  to  be  the  isolated  microsporangia  of  Dolerotheca,  are  repre- 
sented in  the  present  collection.  No  specimen  of  the  entire  organ  was 
found. 


Botany  133 

Pterophyta 

The  members  of  this  division  include  both  the  true  ferns  and  an 
interesting  group  of  plants  called  preferns.  The  preferns  began  to 
evolve  during  mid-Devonian  time  into  plants  which  are  considered  transi- 
tional between  the  earlier  psilophytes  and  the  later  true  ferns.  Knowl- 
edge of  preferns  is  based  on  a  variety  of  fossil  evidence  from  both 
compressions  and  petrifactions. 

Two  orders  of  preferns  exist,  the  Protopteridales  and  the 
Coenopteridales.  It  is  unfortunate  that  the  distinction  between  the  two 
is  highly  artificial,  the  former  known  only  from  compression  fossils  and 
the  latter  from  petrifactions.  Considerable  overlapping  of  the  plants 
included  in  the  two  orders  probably  exists;  but  based  on  the  present 
knowledge,  this  classification  is  the  most  expedient  way  to  identify  these 
plants. 

Several  families  of  the  order  Coenopteridales  are  represented  in  the 
present  collection.  The  family  Botryopteridaceae  is  represented  by  the 
genus  Botryopteris.  The  stem  of  this  genus  is  protostelic,  about  12  mm. 
in  diameter,  and  possessed  a  zone  of  cortex  around  the  stele.  Several 
petioles  branched  from  the  stem,  each  bearing  a  bundle  with  three 
xylem  arms  arranged  in  a  characteristic  W-shape.  The  primary  petiole 
branches  continued  to  divide  and  apparently  terminated  in  slender, 
cylindrical  branchlets. 

Isolated  petioles  of  Botryopteris  are  represented  frequently  in  the 
present  collection.  In  Figure  12  the  typical  W-shape  xylem  arrangement 
of  the  vascular  tissue,  as  well  as  the  surrounding  cortex  region  are  clearly 
evident. 

The  family  Anachoropteridaceae  is  represented  by  the  genus 
Tubicaulis.  The  simple  protostelic  stem  of  this  plant  gave  rise  to  many 
spirally  arranged  petioles.  The  unusual  feature  of  this  plant  is  that  the 
petiole,  as  seen  in  cross  section,  contains  a  C-shape  vascular  trace  with 
the  open  side  of  the  bundle  pointing  toward  the  abaxial  surface.  Very 
little   is   known  about   the   remaining   organs   of  this   interesting   plant. 

Many  isolated  petioles  of  Tubicaulis  are  represented  in  the  present 
collection.  The  C-shaped  vascular  tissue  with  its  abaxial  orientation  are 
shown  in  several  specimens.  The  cortex  surrounding  the  vascular  tissue 
is  also   quite  apparent. 

The  family  Zygopteridaceae  is  represented  by  the  petiole  genus 
Etapteris.  The  distinguishing  feature  of  this  genus  is  the  H-shaped 
arrangement  of  the  vascular  tissue.  In  recent  years,  Etapteris  petioles 
have  been  definitely  correlated  with  a  more  completely  understood  plant 
called     Zygopteris. 

Only  a  few  specimens  of  Etapteris  are  represented  in  the  present 
collection.  Figure  13  illustrates  the  petiole  with  its  H-shaped  xylem 
tissue.  The  cortex  which  surrounds  the  vascular  tissue  in  this  genus  is 
similar  to  the  cortex  of  the  Botryopteris  petiole.

Botany  135 

Only  one  family  of  the  true  ferns  is  represented,  the  Marratiaceae. 
Petrified  material  of  this  family  which  existed  during  the  Mississippian, 
Pennsylvanian,  and  Permian  Periods  is  usually  assigned  to  the  genus 
Psaronius.  This  genus  greatly  resembled  the  modern  tree  ferns  and  was 
one  of  the  dominant  elements  of  the  Pennsylvanian  and  Permian 
Periods.  The  trunk  of  this  plant  was  an  unbranched,  gradually  tapering 
column,  and  was  covered  by  a  dense  mantle  of  adventitious  roots.  The 
mantle  of  roots  was  especially  thick  in  the  lower  trunk  region,  resulting 
in  the  formation  of  a  heavily  buttressed  base.  The  crown  of  the  plant  was 
composed  of  leaves  which  were  few  in  number,  but  of  great  size,  some 
as  long  as  three  meters. 

Two  genera  of  sporangia  exist  which  are  attributed  to  Psaronius, 
with  both  genera  apparently  found  on  the  same  type  of  leaf. 
Cyathotrachus  is  a  rather  large  synangium  consisting  of  7-9  sporangia, 
which  are  arranged  around  a  central  column  for  about  half  their  length. 
Each  sporangium  is  a  distinct  unit  with  a  thin  sporangial  wall  enclosing 
many  spores.  All  of  the  sporangia  are  enclosed  within  a  synangial  cover, 
which  apparently  split  at  maturity  to  release  the  spores.  Scolecopteris  is 
the  genus  of  a  similar  type  of  synangium  which  consists  of  six  rather 
elongate  sporangia  joined  only  at  their  base.  There  is  no  synangial 
cover  in  Scolecopteris. 

Scolecopteris  synangia  are  represented  in  considerable  numbers  in 
the  present  collection,  suggesting  a  rather  widespread  distribution.  When 
the  synangia  are  sectioned  parallel  to  the  leaf  surface,  the  sporangia 
appear  in  cross  section  (Figure  14),  and  the  structure  of  the  thin 
sporangial  walls  may  be  observed.  Figure  15  shows  a  longitudinal  section 
of  Scolecopteris  and  illustrates  the  elongate  nature  of  the  sporangia  and 
their  attachment  to  the  leaf. 

Another  unusual  feature  of  Psaronius  is  the  thick  mantle  of  roots 
which  surround  the  stem.  One  specimen  has  been  reported  which  had  a 
stem  two  inches  in  diameter  and  a  mantle  of  roots  thirty  inches  thick. 
The  broad  mantle  of  roots  in  this  genus  is  composed  of  two  zones,  an 
inner  zone  of  small  roots  imbedded  in  a  cellular  matrix,  and  an  outer 
zone  of  larger,  free  roots.  Each  root  has  a  small,  star-shaped  protostele 
and  a  broad  aerenchymatous  cortex.  The  cortex  is  bounded  by  a  region 
of  thick-walled  hypodermal  cells  which  form  the  outer  portion  of  the 
root.  The  presence  of  the  aerenchymatous  cortex  suggests  the  possibility 
of  a  swampy  habitat  for  the  Psaronius  trees. 

One  of  the  coal  balls  in  the  present  collection  was  found  to  be 
composed  entirely  of  Psaronius  roots.  The  roots  from  this  specimen 
illustrate  the  small  protostele  composed  of  xylem  tracheids  (Figure  16). 
The  region  of  hypodermal  cells  is  also  clearly  evident  in  this  section. 
Several  examples  of  isolated  Psaronius  roots  were  found  in  other  coal 
balls  which  illustrate  the  aerenchymatous  cortex. 

Interpretation 

Benninghoff  (2)  published  a  report  of  a  coal  ball  flora  from  a  mine 
near  Petersburg,  Indiana,  in  which  he  described  thirteen  genera  of  fossil 


136  Indiana  Academy  of  Science 

plants.  The  genera  described  by  Benninghoff,  together  with  genera 
reported  in  selected  Illinois  studies,  are  compared  to  the  genera  in  the 
present  collection  in  Table  2.  Benninghoff  described  three  genera  of 
synangia,  Asterotheca,  Myriotheca,  and  Phytocarpus,  which  are  not  rep- 
resented in  the  present  material  nor  in  any  of  the  Illinois  studies.  All 
other  genera  described  by  Benninghoff  are  included  in  the  present  study. 

The  degree  of  similarity  existing  between  the  assemblage  of  fossil 
plants  of  Indiana  as  represented  in  the  present  collection,  and  the 
assemblage  of  fossil  plants  of  Illinois  is  summarized  in  Table  2. 

Darrah  (3)  has  said  that  the  plant  assemblages  found  in  nearly  all 
American  coal  ball  floras  are  basically  similar.  The  differences  lie 
mainly  in  the  change  of  dominant  genera  from  flora  to  flora,  or  the 
occasional  addition  or  deletion  of  a  few  genera.  The  present  study  tends 
to  support  Darrah's  statement.  Considerable  similarity  exists  between 
the  plant  assemblage  found  in  Illinois  and  the  plant  assemblage  of 
Indiana.  The  present  study  provides  the  basis  for  a  more  detailed 
correlation.

The  striking  similarities  which  appear  between  the  Illinois  studies 
and  the  present  Indiana  material  suggest  that  a  relatively  uniform  flora 
existed  over  portions  of  Illinois  and  Indiana  during  the  Pennsylvanian 
Period.

Algal  Records  for  Three  Indiana  Sewage  Stabilization  Ponds 

C.  Mervin  Palmer 

Advanced  Waste  Treatment  Research  Laboratory,  FWPCA, 
Cincinnati,  Ohio 

Abstract 

Algal  identifications  have  been  recorded  from  376  samples  collected  from 
three  Indiana  sewage  stabilization  ponds  during  a  period  from  May  1962  to 
August  196S.  Although  certain  genera  were  found  frequently  in  all  three  ponds, 
each  pond  had  a  distinctive  algal  flora.  Green  algae  were  invariably  the  most 
abundant  of  the  algal  groups  present.  However,  flagellates  were  also  prominent. 
Of  a  total  of  64  genera  of  the  most  significant  and  abundant  algae  there  were 
29  green  algae,  19  flagellates,  10  blue-green  algae,  and  6  diatoms.  Some  genera 
were  limited  to  the  summr  season,  while  others  were  most  prominent  in 
spring  and  fall  or  in  the  winter.  The  pollution-tolerant  algae  Euglena  and 
Nitzschia  were  abundant  and  persistent  in  all  three  ponds. 

Three  sewage  stabilization  ponds  in  southeastern  Indiana  were 
among  several  throughout  the  United  States  selected  for  biological 
studies,  with  particular  emphasis  on  the  algal  flora.  The  Indiana  ponds 
serve  the  communities  of  Napoleon  and  Sunman  in  Ripley  County  and 
St.  Paul  in  Decatur  County.  These  ponds  range  from  2.9  to  7.9  acres  and 
are  from  3  to  4  feet  deep.  The  respective  populations  served  are  approxi- 
mately 300  to  800  with  a  pond  area  of  about  0.01  acre  per  person.  The 
biochemical  oxygen  demand  (BOD)  at  the  intakes  has  been  ±  500  ppm 
and  for  the  effluents  less  than  50  ppm.  The  Ripley  County  ponds  were 
put  into  use  in  1961  and  the  one  in  Decatur  County  three  years  later. 

Information  on  one  or  more  of  these  ponds  has  been  reported  by 
Kuwahara  (2),  Palmer  (5),  Safferman  (6),  and  Safferman  and  Morris 
(7,  8).  The  first  virus  infecting  a  blue-green  alga  was  isolated  from  one 
of  the  ponds  in  Ripley  County  (6). 

Algal  identifications  were  recorded  from  samples  from  the  two 
Ripley  County  ponds  on  43  different  days  during  all  seasons  between 
May  1962  and  August  1968.  For  the  St.  Paul  pond,  summer  samples  only 
have  been  available,  these  being  obtained  in  1966  and  1968,  with  collec- 
tions on  eight  different  dates.  Four  samples  per  pond  were  obtained  on 
each  date  of  collection  making  a  total  of  376  samples.  Each  set  of  four 
samples  represented  the  following  sites:  A — Water,  near  influent;  B — 
Sludge  or  floating  mat,  near  influent;  C — Water,  near  effluent;  D — Sludge 
or  floating  mat,  near  effluent.  Identification  of  the  algae  in  each  sample 
was  to  genus  and  the  relative  abundance  of  each  was  recorded. 

Records  of  the  microscopic  analyses  of  samples  for  three  dates  for 
Napoleon  and  Sunman  and  two  dates  for  St.  Paul  are  given  in  Table  1. 
The  data  were  selected  to  permit  comparison  of  the  algal  flora  in  the 
three  ponds  and  for  each  pond  at  different  times  of  the  year.  Relative 
abundance  of  all  genera  is  indicated  using  the  figures  from  1  through  5.

Sludge  or  floating  mat  samples  (B  and  D)  often  contained  a  larger 
number  of  algal  genera  than  did  the  water  samples  from  the  same 
locations  (A  and  B). 

The  number  of  genera  of  four  algal  groups  recorded  for  each  of  the 
three  ponds  is  listed  in  Table  2.  In  all  three  ponds  the  green  and  flagellate 
genera  outnumbered  those  of  blue-green  algae  and  diatoms.

The  highest  number  of  genera  recorded  for  any  pond  for  one  day 
was  21.  However,  the  averages  differed  for  the  three  ponds,  being  11  for 
Sunman,  14  for  Napoleon,  and  18  for  St.  Paul.  The  higher  the  number 
of  genera,  the  more  likely  that  wastes  in  the  influent  have  been  stabilized 
as  algal  ingredients.  A  number  of  industrial  wastes,  including  those 
from  dairies  and  food  canneries  are  generally  not  as  readily  assimilated 
by  algae  as  is  typical  household  sewage.  Variations  in  loading  and  in 
environmental  factors  can  also  affect  the  algal  flora.  A  total  of  83  algal 
genera  was  recorded.  Table  3  lists  the  most  abundant  and  significant 
of  these,  together  with  the  number  of  sampling  dates  they  were  recorded 
for  each  pond.  Among  the  64  genera  listed  are  24  non-filamentous  green 
algae,  19  pigmented  flagellates,  10  blue-green  algae,  6  diatoms,  and  5 
filamentous  green  algae. 

Ankistrodesmus,  Chlamydomonas,  Chlorella,  Euglena,  Nitzschia,  and 
Oscillatoria  were  persistent  in  all  three  ponds.  All  are  among  the  top  12 
algal  genera  most  tolerant  of  pollution  (4).  Also  fairly  persistent  in  all 
three  ponds  were  Anacystis,  Oocystis,  Pandorina,  Schizothrix,  and 
Scenedesmus.  All  but  Schizothrix  are  among  the  top  35  pollution-tolerant 
genera  (4).  This  genus  would  also  be  within  the  grouping  if  it  were 
credited  with  the  records  of  its  synonyms  as  recognized  by  Drouet  (1). 

Anabaena,  Chodatella,  Chroomonas,  Closteriopsis,  Closterinm, 
Cryptomonas,  Spirulina,  and  Zoochlorella  were  present  much  more  often 
in  the  Napoleon  pond  than  in  the  other  two  ponds.  Arthrospira  and  par- 
ticularly Pyrobotrys  are  the  only  significant  ones  that  were  distinctive  at 
Sunman.  At  St.  Paul  the  diatom  Cyclotella  was  the  only  distinctive  genus 
that  appeared  more  than  once.  The  interesting  forms  Achnanthes, 
Stigeoclonium,  and  the  blue-green  alga  Johannesbaptistia  were  reported 
once  for  that  pond.  Navicula  and  other  diatoms  (Achnanthes, 
Gomphonema,   Nitzschia)    were   fairly   consistent  in  the   St.   Paul  flora.

Napoleon  and  Sunman  ponds  were  sampled  during  all  months  of 
the  year,  making  possible  a  study  of  seasonal  distribution  of  the  algae. 
While  many  algae  can  be  recorded  as  abundant  during  the  summer,  a 
much  more  restricted  flora  is  found  during  the  winter.  Of  the  flagellates, 
Phacus  and  Chroomonas  were  most  abundant  during  the  spring, 
Pandorina  during  the  summer,  and  Cryptomonas  during  the  autumn  and 
winter.  Chalamydomonas  was  abundant  during  all  seasons  and  Euglena, 
while  present  in  all  seasons,  was  less  abundant  during  the  winter.  The 
diatoms  Nitzschia  and  Navicula  were  present  in  all  seasons.  The  former 
was  much  more  abundant  and  appeared  in  greatest  numbers  in  spring 
and  fall. 

Most  of  the  more  common  green  algae  tended  to  be  primarily  sum- 
mer forms.  These  included  Actinastrum,  Golenkinia,  Kirchneriella, 
Oocystis,  and  Planktosphaeria.  During  the  test  period,  Selenastrum  was 
absent  in  the  fall  and  most  abundant  in  winter.  Scenedesmus  and 
Ankistrodesmus  remained  high  in  numbers  during  fall  as  well  as  sum- 
mer. Oscillatoria  and  Schizothrix,  the  two  most  prominent  blue-green 
algae,  were  recorded  during  all  seasons  and  were  abundant  from  late 
spring  until  at  least  mid-autumn. 

Some  algae  less  common  in  sewage  ponds,  but  present  in  one  or  more 
of  the  Indiana  ponds,  included  the  diatoms  Cyclotella  and  Hantzschia, 


Botany  145 

the  blue-green  algae  Arthrospira,  Johannesbaptistia,  and  Raphidiopsis, 
the  green  algae  Actinastrum,  Chodatella,  Closterium,  Dictyosphaerium, 
Selenastrwm,  Spirogyra,  and  Ulothrix,  and  the  flagellate  algae 
Chlorogonium,  Chroomonas,  Cryptomonas,  Eudorina,  Massartia, 
Phacotus,  Pteromonas,   and  Pyrobotrys. 

On  each  collection  date  two  samples  were  taken  from  the  influent 
area  and  two  from  the  effluent  area  of  the  pond.  Microscopic  analyses  of 
these  samples  indicated  very  little  difference  between  the  algal  flora  of 
the  influent  and  effluent  areas.  This  could  be  the  result  of  rapid  mixing 
of  the  water  throughout  the  pond.  It  could  be  the  result  of  rapid  oxida- 
tion and  stabilization  of  the  sewage,  including  that  in  the  influent  area. 

At  Napoleon  and  St.  Paul  the  more  abundant  algae  were  generally 
present  in  each  set  of  samples  collected.  This  pattern  indicates  the  con- 
stant quality  and  quantity  of  sewage  entering  the  ponds.  At  Sunman, 
Scenedesmus  was  rare  to  absent  after  1963  and  Ankistrodesmus  was 
rare  to  absent  after  1965.  Chlorella  became  more  abundant  in  1965  and 
the  related  genus  Nannochloris  appeared  in  large  numbers  in  May  1966. 
Both  persisted  in  abundance  afterwards.  Such  a  change  in  the  flora  has 
been  considered  elsewhere  to  be  due  to  the  development  of  partial 
anaerobic   conditions    (3). 

The  algal  flora  of  three  sewage  stabilization  ponds  in  Indiana  was 
composed  of  an  average  of  11  to  18  genera  of  algae.  The  most  abundant 
and  persistent  forms  were  all  ones  previously  classified  as  highly  tolerant 
to  organic  enrichment.  In  addition  to  the  many  green  algae  a  large 
number  of  flagellate  algae  were  present,  some  of  these  being  seasonal. 
Blue-green  algae  and  diatoms,  with  the  exception  of  Nitzschia,  were  not 
common. 

Collection  of  many  of  the  samples  used  in  this  study  was  made  by 
Dr.  Robert  Safferman  of  the  Advanced  Waste  Treatment  Research 
Laboratory;  appreciation  is  expressed  to  him  for  his  cooperation.

Leaf  abscission  is  a  terminal  developmental  sequence  initiated  by 
the  onset  of  senescence  (excision  and  deblading  in  experiments  with 
explants)  and  terminated  by  separation  of  the  leaf  from  the  main  axis 
of  the  stem  (3,  4,  8,  9,  13).  Studies  of  abscission  are  greatly  facilitated

by  use  of  explants  (excised  abscission  zones  and  adjacent  tissues)  which 
respond  uniformly  and  rapidly  but  exhibit  widely  varying  rates  of 
abscission  depending  upon  treatment  conditions. 

The  behavior  of  an  explant  population  is  described  by  a  transition 
profile,  a  simple  sigmoid  defined  by  two  parameters:  the  position  of  the 
midpoint  (time  to  50%  separation)  and  the  steepness  of  the  slope  at 
this  point  (or  by  an  equivalent  parameter,  the  transition  width).  The 
time  at  which  abscission  reaches  the  midpoint  of  the  transition  is  a 
measure  of  the  rapidity  at  which  separation  layers  are  formed.  The 
transition  width  is  a  measure  of  the  heterogeneity  of  the  population.  A 
very  broad  transition  is  indicative  of  a  heterogeneous  population  whereas 
a  sharp  transition  is  indicative  of  a  synchronous  population. 

With  bean,  natural  abscission  of  primary  unifoliate  leaves  occurs 
between  30  and  40  days  after  planting  with  plants  grown  under  green- 
house conditions  (10).  Explants  of  primary  leaves  reach  50%  separation 
at  about  100  hours  following  the  procedures  of  Leopold  and  coworkers 
(5,  10,  13).  It  is  desirable  to  utilize  explants  with  very  sharp  transition 
profiles  (synchronous  response).  For  many  types  of  abscission  studies, 
it  would  be  equally  desirable  to  utilize  explants  with  50%  separation 
within  a  day  after  cutting  rather  than  the  usual  100  hours.  The  rapid 
abscission  rate  would  permit  initiation  and  termination  of  kinetic  studies 
during  a  single  working  day  instead  of  over  a  period  of  several  days  or 
weeks.

Materials  and  Methods 

Bean  plants  (Phaseolus  vulgaris  L.,  var  Red  Kidney)  were  grown 
under  greenhouse  or  controlled  environmental  conditions.  Unless  specified 
otherwise,  explants  were  cut  from  unifoliate  leaves  of  10  to  20  day  old 
plants  grown  in  metal  flats  containing  potting  soil  overlayed  with  sand. 
The  flats  were  filled  to  a  depth  of  5  cm  with  the  soil  followed  by  a  layer 
of  seeds  which  were  then  covered  to  a  depth  of  about  1  cm  with  sand. 
Greenhouse-grown  plants  were  supplemented  with  low  intensity  fluores- 
cent and  incandescent  light  to  provide  a  16  hr.  photoperiod. 

The  1  to  2  cm  long  debladed  explants  were  cut  to  include  at  least 
5  mm  of  tissue  on  either  side  of  the  distal  abscission  zone  at  the  pulvinus-

petiole  juncture  (10).  Unless  specified  otherwise,  approximately  20 
explants  were  inserted  vertically  (usually  with  the  petiole  end  down) 
to  a  depth  of  4  mm  in  1%  agar  in  1  X  5  cm  petri  dishes.  To  facilitate 
inserting  the  pulvinus  end  of  the  explants  into  agar,  an  agar  concentra- 
tion of  0.7%  was  used.  Rate  of  separation  of  explants  was  independent 
of  agar  concentration  over  the  range  0.7  to  2%.  Results  are  an  average 
of  at  least  3  experiments. 

The  time  of  separation  layer  formation  was  estimated  from  the 
time  when  application  of  pressure  to  the  pulvinus  readily  brought  about 
separation.  Details  of  individual  experiments  are  given  in  the  text. 

Results 

Transition  profiles  for  explants  prepared  from  greenhouse-grown 
bean  plants  (Fig.  1)  showed  a  broad  transition  width  when  assays  were 
conducted  at  23°.  In  low  intensity  (100  ft-c)  light,  explants  began  to  ab- 
scise between  60  and  70  hours  after  cutting  but  did  not  reach  100%  abscis- 
sion until  after  170  hours  (50%  separation  at  120  hours).  With  green- 
house-grown plants  (high  light  intensity  and  long  photoperiod), 
abscission    was    accelerated    when    explant    assays    were    conducted    in

darkness  (50%  separation  at  100  hours).  Except  for  explants  prepared 
from  plants  grown  under  high  light  intensity  and  long  photoperiod,  ab- 
scission was  generally  faster  at  22°  when  explants  were  incubated  in 
the  light  (Table  1). 

Abscission  is  extremely  sensitive  to  temperature  (Figure  2;  Table  1). 
Abscission  was  not  detected  at  temperatures  below  16°  or  above  36°. 
Increasing  the  temperature  from  22°  to  26°  markedly  accelerated  ab- 
scission (50%  separation  at  120  hours  at  22°  vs  50%  separation  at  24 
hours  at  26°).  The  temperature  response  curve  for  experimental  leaflet 
abscission  exhibited  a  broad  optimum  between  26  and  30°,  with  a  decline 
in  rate  at  32°.  Between  32  and  36°,  abscission  was  further  delayed  and 
many  of  the  explants  did  not  abscise.  Increasing  temperatures  decreased 
the  midpoint  of  the  transition  profiles  (Fig.  2)  and  at  the  same  time 
increased  the  steepness  of  the  slope  (decreasing  the  transition  width) 
as  shown  in  Figure  3  for  greenhouse-grown  plants  (compare  28°,  Fig.  3 
with  22.5°,  Fig.  3  and  23°,  Fig.  1).  The  temperature  at  which  the  plants 
were  grown  prior  to  harvesting  the  explants  had  much  less  of  an 
effect  on  abscission  rate  than  the  temperature  during  the  explant  bio- 
assay  (Table  1). 

Effects  of  light  on  abscission  were  less  pronounced  than  the  effects 
of  temperature.  The  most  marked  effect  was  the  qualitative  response 
to  light  vs.  dark  (Fig.  1,  Table  1)  which  varied  according  to  the  light 
intensity   and   photoperiod   at  which  the   plants   were   grown.   With   all

plants  (except  those  grown  at  high  light  intensity  and  long  photoperiod), 
incubating  explants  in  low  light  (100  ft-c)  markedly  accelerated  abscis- 
sion. Increasing  the  light  intensity  from  the  range  700  to  1,000  ft-c  to 
4,500  to  4,800  ft-c  resulted  in  no  further  change  in  the  rate  of  separation 
layer  formation  (Table  2).  When  explant  assays  were  conducted  at  22.5°, 
separation  rate  was  inversely  related  to  photoperiod  with  photoperiods 
of  8,  12,  16  and  20  hours.  At  30°,  the  response  to  photoperiod  was  ir- 
regular.

The  photoperiod  at  which  the  plants  were  grown  affected  separation 
layer  formation  in  explants  assayed  under  continuous  light  but  differ- 
ences were  not  marked.  Explants  prepared  from  plants  grown  under  low 
light  intensity  tended  to  abscise  more  rapidly  in  the  light  than  those 
from  plants  grown  at  high  light  intensity.  This  response  was  independent 
of  photoperiod  and  assay  temperature  (Table  1).  Most  rapid  abscission 
was  obtained  from  bean  plants  grown  at  22.5°,  700  to  1000  ft-c  and  an 
8  hr  photoperiod.  All  differences  due  to  growth  conditions  of  the  plants 
tended  to  be  minimized  when  explant  assays  were  conducted  at  a  near 
optimum  temperature  of  29°  as  compared  with  a  suboptimal  temperature 
of  22°  (Table  1).  Explants  from  plants  grown  in  complete  darkness 
(completely  etiolated  condition)  did  not  absice  when  subsequently  incu- 
bated either  in  light  or  darkness. 

Time  to  50%  separation  decreased  with  increasing  age  of  the  plant 
particularly  when  assays  were  conducted  at  23°.  However,  at  optimum 
temperature,  age  of  the  plant  did  not  appear  to  be  a  significant  variable 
(Fig.  4).  The  most  marked  response  to  age  was  from  plants  grown  at 
22.5°,  a  12-hour  photoperiod  and  a  light  intensity  of  700  to  1000  ft-c.

Under  these  growing:  conditions,  the  midpoint  of  abscission  was  shortened 
by  about  5  hours  comparing  12  day  old  and  20  day  old  plants. 

With  assays  conducted  in  light,  acceleration  of  abscission  was 
achieved  by  inverting  the  explants  (incubation  with  the  pulvinar  end 
in  agar).  Inverting  the  explant  was  without  effect  in  the  dark  (Table  3). 
Ethylene  when  applied  to  explants  at  ambient  pressure  and  temperature 
provided  a  further  stimulation  of  abscission  rate.  The  optimum  con- 
centration was  near  1  ppm  (Fig.  5).  In  some  species,  the  stipules  are 
a  natural  source  of  ethylene.  With  our  explants,  stipulate  and  exstipulate 
explants  behaved  similarly  (Table  4)  although  abscission  rate  was  re- 
duced slightly  by  removing  both  stipules.  A  shortening  of  the  time  to 
50%  separation  equivalent  to  that  with  ethylene  was  obtained  by 
supplying  galactose  to  the  agar  (Fig.  6).  These  experiments  were  con-

optimum  galactose  concentration  was  2%  and  explants  treated  with  20% 
galactose  did  not  abscise.  Under  similar  conditions  of  treatment,  sucrose 
and  glucose  also  stimulated  abscission  but  not  to  the  extent  exhibited  by 
galactose  (Table  5).

marked  shortening  of  the  midpoint.  When  supplied  together  at  optimal 
concentrations,  ethylene  and  galactose  were  additive  in  their  effects  on 
rate  of  separation  layer  formation  (Fig.  7).  The  studies  with  ethylene 
were  conducted  in  sealed  flasks  with  inverted  explants  (pulvinar  end

More  detailed  transition  profiles  of  rapidly  abscising  explants  (Fig. 
8)  show  a  transition  width  of  approximately  2  hours  and  a  midpoint  at 
12  hours  when  explants  were  prepared  from  plants  grown  at  constant 
temperature  (22.5°),  low  light  intensity  (700  to  1000  ft-c)  and  short 
(8  hr)  photoperiod.  With  explants  from  greenhouse-grown  plants  (vari- 
able temperature,  long  photoperiod,  high  light  intensity),  the  midpoint 
was  at  14  hours  (2  hours  later).  When  compared  under  less  favorable 
conditions  (in  the  absence  of  inducers,  upright  position  and  22°),  their 
midpoints  differed  by  as  much  as  70  hrs  (50  hrs  to  50%  separation  from 
explants  from  plants  grown  at  22.5°,  low  light  and  8  hr  photoperiod  vs. 
120  hr  for  explants  from  greenhouse-grown  plants,  Table  1,  Fig.  1).  The 
equalizing  effect  of  optimum  conditions  for  the  explant  assay  illustrated 
in  Figure  8  was  evident  throughout  the  study.  In  general,  differences  due 
to  growing  conditions  of  the  plants  were  minimized  as  conditions  of  the 
explant  assay  were  optimized  (Table  1).  Also  minimized  as  optimum 
conditions  of  explant  assay  were  approached  were  differences  among 
individual  members  of  each  population.  The  net  result  was  a  steepening 
of  the  transition  profile  (Fig.  8). 

Discussion 

External  factors  such  as  climatic  conditions  have  long  been  known 
to  influence  abscission  of  leaves  from  intact  plants  (3,  4).  Low  carbo- 
hydrate levels  favor  rapid  abscission.  Moderate  nitrogen,  low  water  sup- 
ply, high  light  intensity  and  conditions  of  carbohydrate  accumulation 
reduce  or  retard  abscission  (13).  Light  also  may  have  an  effect  through 
photoperiod.  Olmsted  (11)  observed  that  constant  photoperiods,  re- 
gardless of  length,  resulted  in  delayed  abscission  and  senescence. 

The  effect  of  environment  on  experimental  leaflet  abscission  (studies 
utilizing  explants)  has  not  been  studied  extensively.  Previously,  Yama- 
guchi  (reviewed  by  Addicott  (3))  found  that  the  formation  of  the 
abscission  layer  in  bean  explants  exhibited  a  temperature  response 
curve  with  a  maximum  between  25  and  30°  and  the  effects  of  light  and 
C02  on  explant  abscission  were  examined  by  Biggs  and  Leopold   (5). 

Being  a  physiological  process,  abscission  is  extremely  sensitive  to 
temperature  particularly  over  the  range  16  to  26°.  Increasing  the  tem- 
perature from  22°  to  24°,  for  example,  may  shorten  the  time  of  50% 
separation  of  explants  by  nearly  50%.  Between  26°  and  30°,  temperature 
has  little  effect  on  abscission  rate  with  an  optimum  near  29°.  In  earlier 
abscission  experiments  involving  explants  at  about  23°,  it  is  probable  that 
much  of  the  variation  was  due  to  variations  in  temperature.  The  tem- 
peratures at  which  the  plants  were  grown  prior  to  harvesting  the  ex- 
plants  has  much  less  of  an  effect  on  abscission  rate  than  the  temperature 
during  the  explant  bioassay. 

The  response  of  explants  to  light  is  more  variable  and  less  pro- 
nounced than  that  due  to  temperature.  With  plants  grown  under  low  light 
intensity  (conditions  that  tend  to  minimize  accumulation  of  carbohydrate 
reserves),  abscission  of  explants  occurs  more  rapidly  in  light  than  in 
darkness.    However,    when    plants    are    grown    in    high    light    intensity 


158  Indiana  Academy  of  Science 

(conditions   favoring    accumulation    of   carbohydrate   reserves)    just   the 
opposite  is  true,  i.e.  explants  abscise  more  rapidly  in  the  dark. 

This  light-induced  delay  of  abscission  with  plants  grown  at  high 
light  intensity  was  investigated  by  Biggs  and  Leopold  (3).  They  found 
that  plants  in  a  C02-free  atmosphere  under  300  ft-c  of  light  abscised  at 
the  same  time  as  those  kept  in  the  dark  with  or  without  C02,  while  those 
kept  in  ambient  air  were  delayed  by  about  40  hours.  They  concluded 
that  the  effect  of  light  was  due  to  photosynthesis  since  in  their  studies 
the  effect  of  light  was  eliminated  by  added  sucrose. 

In  our  studies,  conducted  with  greenhouse-grown  plants,  sucrose  and 
glucose  had  slight  stimulatory  effects  on  abscission  and  any  regular 
correlation  among  light,  C02,  photosynthesis,  carbohydrate  accumulation 
and  abscission  seemed  doubtful.  A  further  complication  arose  from  the 
unexplained  observations  that  explants  abscised  faster  with  the  pulvinus 
end  in  agar  (petiole  end  up)  than  when  the  petiole  end  was  in  agar 
(pulvinus  end  up)  but  only  in  light.  In  darkness,  the  explant  apparently 
did  not  sense  which  end  was  up. 

A  possible  indirect  involvement  of  photosynthesis  in  leaf  abscission 
would  be  through  CO-  removal  as  it  effects  the  response  of  the  plant 
to  ethylene.  Ethylene  is  a  natural  promoter  of  abscission  (1,  2,  6,  12) 
and  carbon  dioxide  (CO?)  is  a  competitive  inhibitor  of  its  action.  Thus, 
a  simple  explanation  of  the  effects  of  light  and  temperature  on  experi- 
mental leaflet  abscission  might  be  found  in  a  consideration  of  the  com- 
bined rates  of  photosynthesis  and  respiration  as  they  affect  C02  levels. 
A  buildup  of  CO2  within  the  petri  plates  containing  the  explants  might 
interfere  with  the  normal  acceleration  of  separation  layer  formation  by 
endogenous  ethylene,  particularly  at  high  temperatures.  Under  condi- 
tions where  respiratory  substrates  are  non-limiting,  photosynthesis 
would  be  expected  to  substantially  reduce  the  C02  content  of  the  gas 
phase  of  explants  incubated  in  the  light  with  a  corresponding  accelerated 
rate  of  separation  layer  formation.  Both  ethylene  and  galactose  appear 
to  accelerate  abscission  through  their  specific  action  in  the  induction  of 
a  pectinase  catalyzing  the  hydrolysis  of  the  cementing  substances  be- 
tween adjacent  cell  layers  of  the  abscission  zone  (10). 

With  cotton  petioles,  Hall  and  Liverman  (7)  found  that  abscission 
was  accelerated  in  proportion  to  increased  light  intensity  up  to  2,500 
ft-c  but  light  intensities  from  6,000  to  8,000  ft-c  delayed  abscission  sig- 
nificantly. Acceleration  was  obtained  with  red,  far-red,  fluorescent  and 
ultraviolet  light  but  the  effects  of  light  intensity  on  abscission  have  not 
been  studied  extensively.  Similarly,  in  our  studies,  plants  grown  under 
high  light  intensity  were  delayed  in  their  abscission  response  as  com- 
pared to  plants  grown  under  low  light  intensity. 

Throughout  these  studies,  light  and  temperature  have  been  most 
effective  in  regulating  explant  abscission  during  incubation  of  the  ex- 
plants.  Abscission  of  explants  is  only  little  influenced  by  the  conditions 
under  which  the  plants  are  grown  except  for  extremes  of  temperature, 
nutrition    and    photoperiod    (Table    6).    Here,    conditions    favoring    slow

growth  of  the  plants  tend  to  be  associated  with  a  reduced  rate  of  separa- 
tion layer  formation. 

Summary 

Separation  layer  formation  in  explants  of  red  kidney  bean  was 
markedly  accelerated  by  increasing  temperature  between  16  and  26°  C 
with  an  optimum  between  28  and  30°.  Light  effects  were  largely  qualita- 
tive. Quantitative  changes  in  light  intensity  and  photoperiod  had  little 
effect  on  the  abscission  response  when  explant  assays  were  conducted  at 
optimum  temperatures.  Light  and  temperature  effects  on  explant  abscis- 
sion were  largely  restricted  to  the  explants  themselves  with  minor 
modulations  due  to  the  environmental  history  of  the  plants  from  which 
the  explants  were  prepared. 

By  combining  near  optimal  growing  conditions  of  the  plants  prior 
to  preparation  of  the  explants,  optimum  temperature  and  continuous 
light  during  the  explant  assay  in  conjunction  with  two  inducers  of  pec- 
tinase  (galactose  and  ethylene)  supplied  under  optimal  conditions,  we 
shortened  the  time  of  experimental  leaflet  abscission  from  100  hours  to 
12  hours.  The  development  of  an  experimental  system  in  which  the  time 
from  excision  of  the  explant  to  separation  layer  formation  could  be  con- 
fined to  a  period  of  8  hours  or  less  would  be  of  interest  not  only  from 
the  standpoint  of  practical  defoliation  but  to  expedite  certain  kinetic 
analyses  of  abscission  events  as  well.

The  Fine  Structure  of  the  Ventral  Horn  Neuron  in  the  Calf  Spinal  Cord. 

E.  J.  Hinsman  and  Kathleen  Moe,  Purdue  University. — Tissues  col- 
lected from  the  ventral  horn  of  the  lumbar  spinal  cord  of  gluteraldehyde 
perfused  calves  were  examined.  Study  was  directed  toward  the  larger 
neurons  and  dendritic  interrelationships.  The  large  neurons  appeared 
similar  in  appearance  to  large  motor  neurons  which  have  been  described 
from  other  species.  In  areas  of  dendritic  apposition  interdendritic  mem- 
brane modifications  were  found  which  appeared  similar  to  desmosomes. 
These  consisted  of  the  thickening  of  apposed  dendritic  membranes,  an 
increased  intercellular  space  and  electron  dense  cytoplasmic  condensa- 
tions.  Implications  of  their  presence  will  be  discussed. 

An  Intranuclear  Structure  in  Neurons  of  Human  Cerebral  Cortex.  Itaru 
Watanabe,  Sheila  Donahue,  and  Wolfgang  Zeman,  Indiana  Univer- 
sity Medical  Center. — Examination  in  the  electron  microscope  of  cerebral 
cortical  biopsy  material  from  seven  children  with  various  intractable  dis- 
orders of  the  central  nervous  system  revealed  occasional  peculiar  struc- 
tures in  the  nuclei  of  nerve  cells.  This  structure  is  made  up  of  filaments 
approximately  100  A  in  diameter.  There  is  variation  in  the  appearance 
of  this  structure  which  is  probably  due  to  the  angle  of  the  section.  The 
filaments  are  seen  in  bundles,  and  forming  a  lattice,  also  as  round  ele- 
ments in  cross  section  between  parallel  filaments  bearing  resemblance 
to  a  corncob.  The  whole  structure  is  of  unknown  length,  the  longest  ob- 
served measuring  more  than  5/a.  The  greatest  width  observed  is 
1.2/4,  but  more  often  they  measure  only  20  to  120  m/x.  They  were  seen  in 
both  sexes,  ages  from  2  to  9  years,  in  six  different  disorders,  but 
always  in  nerve  cells.  Such  structures  have  been  observed  in  various 
vertebrates.  Their  significance  is  unknown. 

Chemical  Composition  of  Membrane  Fractions  Isolated  from  Rat  Liver  in 
Relation  to  Membrane  Differentiation  During  Secretion.  Wayne  Yung- 

hans  and  D.  James  Morr£,  Purdue  University. — The  chemical  composi- 
tions of  Golgi  apparatus,  endoplasmic  reticulum  (ER),  and  plasma  mem- 
brane were  compared.  The  ratios  of  protein  to  lipid  in  Golgi  apparatus 
and  plasma  membrane  were  similar  but  less  than  for  ER.  Phospholipids 
of  the  three  membrane  fractions  were  similar  but  the  sterol  content  of 
Golgi  apparatus  was  intermediate  between  that  of  ER  and  plasma  mem- 
brane. Carbohydrate,  RNA,  and  DNA  were  found  in  negligible  amounts 
in  the  Golgi  apparatus  fraction  indicating  low  contamination  from 
glycogen,  ribosomes,  and  nuclear  material. 

Disc    electrophoresis    patterns    of    structural    proteins    from    Golgi 
apparatus  and  ER  were  similar  but  different  from  those  of  plasma  mem-

hrane.  Structural  protein  of  plasma  membrane  separated  into  a  character- 
istic two-band  pattern  with  corresponding  bands  being  present  in  both 
Golgi  apparatus  and  ER.  The  structural  protein  pattern  from  mito- 
chondria showed  several  bands  not  present  in  the  patterns  from  the 
other  membrane  fractions.  These  results  together  with  electron  micro- 
scopic evidence  showed  the  Golgi  apparatus  to  be  a  unique  component 
of  the  endomembrane  system.  However,  its  chemical  composition  was 
intermediate  between  that  of  ER  and  plasma  membrane  and  consistent 
with  a  functional  role  of  the  Golgi  apparatus  as  a  site  of  endomembrane 
differentiation  during  secretion.  (Supported  in  part  by  grants  from  the

An  Electron  Microscopic  Study  of  Zinc  Iodide-Osmium  Staining  of  the 
Golgi   Apparatus  of   Rat   Intestinal   Epithelial    Cells.     K.    M.    Mak    and 

R.  A.  Jersild,  Indiana  University  Medical  Center. — A  modification  of  the 
zinc  iodide-osmium  (ZIO)  impregnation  technique,  used  for  the  staining 
of  synaptic  vesicles  at  cholinergic  junctions  (Akert  and  Sandri,  Brain 
Res.,  7:286,  1968),  has  been  applied  to  intestinal  epithelial  cells  of  the  rat 
jejunum  in  an  attempt  to  localize  choline-containing  phospholipids. 
Results  showed  that  an  electron  dense  reaction  product  was  localized 
within  the  Golgi  apparatus.  In  starved  animals,  one  or  two  of  the  Golgi 
cisternae  were  ZIO-positive  while  associated  vacuoles  remained  negative. 
In  lecithin-fed  animals,  an  increasing  number  of  ZIO-positive  cisternae 
were  observed.  In  addition,  reaction  product  was  seen  deposited  around 
droplets,  presumably  of  fat,  accumulated  in  the  Golgi  vacuoles.  Treat- 
ment of  tissues  in  a  solution  containing  either  potassium  iodide-Os04 
(KIO),  zinc  sulfate-Os04,  or  Os04  alone  failed  to  elicit  a  reaction  prod- 
uct within  the  Golgi  apparatus.  Thus,  the  reaction  product  is  specific  to 
ZIO  mixture.  The  affinity  of  ZIO  for  the  Golgi  apparatus  was  inhibited 
by  pretreatment  of  tissues  with  KIO,  suggesting  that  KIO  and  ZIO  were 
reacting  with  the  same  substrate.  Extraction  of  tissue  lipids  with 
chloroform-methanol  prevented  the  Golgi  response  to  ZIO.  It  is  sug- 
gested in  this  study  that  the  Golgi  apparatus  is  a  site  of  accumulation 
of  phospholipids.  (Supported  by  PHS  Research  Grant  AM  11721-01

The  Ultrastructural  Features  of  Intraoral  Lichen  Planus,  Simplex.   J.  B. 

Whitten,  Jr.,  Indiana  University,  Department  of  Oral  Pathology,  Indi- 
anapolis.— Lichen  planus  is  a  chronic,  benign,  dermatologic  disease  which 
is  usually  self-limiting.  The  skin  lesions  are  elevated,  scaly,  biolaceous 
plaques  which  are  puritic  and  tend  to  expand  and  coalesce  forming 
larger  lesions.  The  oral  disease  exists  in  several  forms:  namely  (1) 
simple,  (2)  erosive,  (3)  bullous,  and  (4)  hypertrophic.  The  lesions  are 
elevated  bluish  white  lines  which  cross  forming  beads.  In  other  cases 
bluish  white  plaques  of  varying  size  occur  without  clinical  identity. 

Biopsies  of  five  patients  with  the  simple  form  of  the  intraoral  disease 
were  examined  with  the  light  and  electron  microscopes.  The  tissue  for 
light  microscopy  was  fixed  in  10%  formalin,  embedded  in  paraffin,  sec- 
tioned at  about  6/x  and  stained  with  hematoxglin  and  eosin.  The  remain- 
ing tissue  for  electron  microscopy  was  fixed  in  4%  glutaraldehyde,  post 


Cell  Biology  163 

fixed  in  osmic  tetraoxide,  embedded  in  Epon  812,  sectioned  at  600  A  with 
glass  knives  and  Porter-Blum  ultramicrotomes,  mounted  on  uncoated 
200-mesh  copper  grids,  and  stained  with  lead  citrate  and  uranyl  acetate. 

Three   phases    of   lichen    planus    were    observed    on    ultrastructural 
examination. 

Stage  I  — Particulate  accumulations  were  found  within  some  of  the 
spinous  cells.  The  particles  were  composed  of  five 
(usually)  electron-dense  bodies  30  A  in  diameter  set  in 
a  much  less  electron  dense  amorphous  material.  Sur- 
rounding the  dense  bodies  were  clear  zones  10-20  A  in 
thickness. 

Stage  II  — The  basal  epithelial  cell  layers  showed  considerable 
intercellular  edema  with  occasional  interepithelial  inflam- 
matory cells  usually  lymphocytes.  The  superficial  lamina 
propria,  beneath  the  anchoring  fibers  and  lamina  densa, 
was  altered.  The  usual  collagen  fibers  were  replaced  by 
an  amorphous  material  about  3/u  to  5/x  in  thickness. 

Stage  III — The  deep  spinous  and  basal  epithelial  as  well  as  the 
superficial  lamina  propria  is  degenerated  and  necrotic. 
In  these  areas  aggregates  of  bacteria  were  often  associ- 
ated with  the  most  severe  degeneration.  This  was  present 
even  though  the  surface  epithelium  was  intact. 

Direct  Studies  of  Nuclear  Movements  in  Schizophyllum  commune. 
Donald  J.  Niederpruem  and  Ralph  A.  Jersild,  Indiana  University  Medi- 
cal Center. — Past  investigations  employed  indirect  genetic  techniques  to 
quantitate  nuclear  migration  in  Schizophyllum  commune.  The  current 
study  employed  living  hyphae  of  5.  commune  and  compared  nuclear 
movements  in  homokaryotic  mycelia,  dikaryotic  mycelium  and  an 
AxBmut  homokaryon  of  this  mushroom.  Rates  of  nuclear  movement  were 
measured  by  phase  contrast  microscopy  and  the  employment  of  an 
ocular  micrometer,  using  hyphal  apices  and  septa  as  reference  points. 
Forward  nuclear  movements  were  observed  in  growing  hyphal  apices  of 
homokaryotic  mycelia  and  the  dikaryon.  Nuclear  movements  occurred 
within  the  range  of  hyphal  growth  and  could  account  for  the  maintenance 
of  centrally  located  nuclei.  Opposed  nuclear  movements  after  mitosis 
greatly  exceeded  the  rate  of  apical  growth.  Septum  disruption  and 
extremely  rapid  nuclear  movements  were  recorded  in  an  AxBmut 
homokaryon.  Neither  cytoplasmic  streaming  nor  actively  participating 
granules  or  filaments  could  account  for  any  of  these  nuclear  movements. 
Glutaraldehyde-fixed  hyphae  were  examined  by  electron  microscopy  and 
revealed  microtubular   elements. 

Plasma  Cell  Antibody  Against  Bovine  Serum  Albumin  in  the  Rabbit 
Appendix  as  Revealed  by  the  Fluorescent  Antibody  Technique.  John  F. 
Schmedtje,  Indiana  University  School  of  Medicine. — Evidence  is  accumu- 
lating that  heterologous  serum  protein  can  be  absorbed  through  the 
normal  gut  epithelium  of  adult  mammals.    In  the  present  experiment, 


164  Indiana  Academy  of  Science 

bovine  serum  albumin  (BSA)  was  intubated  into  the  appendiceal  lumen  of 
the  adult  living  rabbit.  Three  weeks  later,  BSA  was  added  to  the  food  and 
water  for  one  week.  The  appendix  was  removed,  and  portions  were  quick 
frozen  and  subsequently  sectioned  in  a  cryostat.  Adjacent  sections  were 
stained  with  H  and  E.  Purified  BSA  and  goat  anti-BSA  conjugated  with 
fluorescein  isothiocyanate  were  used,  according  to  the  Coons  technique,  to 
identify  any  intracellular  antibody  against  BSA. 

Antibody  against  BSA  was  present  in  plasma  cells  beneath  the 
appendiceal  luminal  epithelium  and  beneath  the  outer  epithelium  of 
appendiceal  crypts.  Antibody  positive  cells  were  not  present  in  control 
rabbits  that  had  not  received  the  intubation  of  BSA. 

The  results  support  the  hypothesis  that  the  intubated  BSA  was 
absorbed  and  acted  as  a  sensitizing  agent.  The  results  also  support  the 
hypothesis  that  absorption  of  the  oral  doses  occurred  through  the  gastro- 
intestinal tract,  that  these  acted  as  challenge  doses,  and  that  this  induced 
plasma  cell  antibody  production  in  the  appendix  wall. 

Tumor  Cell  Mitotic  Activity  in  Mice  Treated  with  Antigenic  Materials. 

William  E.  Stovall  and  Gordon  L.  Rosene,  Ball  State  University. — ■ 
Current  interest  in  tumor  specific  immune  mechanisms  has  prompted  this 
pilot  study  to  investigate  such  mechanisms  in  Strong  A  mice  afflicted 
with  spontaneous  mammary  carcinoma.  The  majority  of  previous  work, 
excluding  clinical  investigations,  involved  transplantable  tumors. 

Five  groups  of  animals  were  employed,  consisting  of  one  untreated 
control  group  and  four  receiving  periodic  injections  of  various  antigenic 
materials.  Two  groups  received  rabbit  serum.  The  remaining  two  were 
given  tumor  combined  with  Freunds  adjuvant.  Serum  recipient  groups 
received  24  injections  during  a  37-day  period.  Adjuvant  recipients 
received  10  injections  during  the  same  period.  Animals  were  sacrificed 
at  12:00  noon.  Histological  sections  of  the  tumors  were  made  and  stained 
with  H  and  E.    Tumor  cell  mitotic  indices  were  determined. 

Data  significance  was  determined  using  the  Student  t  test.  Mean 
mitotic  index  values  from  the  two  rabbit  sera  recipient  groups  were 
significantly  different  (5%  level)  from  the  control  group.  Mean  mitotic 
indices  obtained  from  the  two  Freunds  adjuvant  groups  were  not  sig- 
nificantly different  from  the  control  group.  The  absence  of  significance 
in  these  two  groups  was  due  to  extreme   data  variability. 

It  was  anticipated  that  injected  materials  would  evoke  an  auto- 
immune response  in  the  recipient  mouse.  Literature  reports  suggest  that 
spontaneous  tumors  are  sometimes  weakly  antigenic.  These  procedures 
were  intended  to  produce  an  enhancement  of  such  a  response.  Significant 
decrease  in  tumor  cell  mitotic  indices  could  indicate  a  decrease  in  tumor 
metabolic  activity. 

Microimmunoelectrophoresis  of  Human  Blood  in  Regard  to  the  Study  of 
the  Gc  System.  Shirley  Frances  (Archibald)  Smalley,  Ball  State 
University. — This  study  was  conducted  in  order  to  determine  if  the  Gc 
protein  could  be  accurately  and  economically  identified  using  a  normal  lab- 


Cell  Biology  165 

oratory  technique.  If  the  test  could  be  adapted  to  a  routine  laboratory  pro- 
cedure, it  would  be  possible  to  use  the  Gc  determination  in  identifying 
the  questionable  parentage  in  a  legal  paternity  suit.  Hirschfeld  ct  al. 
and  Beam  and  Cleve  in  previous  experimental  work  have  established  the 
Gc  inheritance  line. 

Also,  this  study  was  conducted  on  two,  three  generation  families. 
One  family  was  Negro  and  the  other  family  Caucasian  of  Anglo-Saxon 
descent.  The  gene  frequencies  were  determined  for  three  generation 
families. 

The  general  technique  involved  the  collection  of  blood  specimens 
for  determination  of  serum  protein.  The  serum  was  then  treated  by 
microimmunoelectrophoresis  on  a  cellulose  membrane.  The  Gc  precipi- 
tation arcs  were  compared  to  control  Gc  precipitation  arcs  and  identified 
for  the  correct  Gc  type. 

The  data  collected  did  show  that  the  microimmunoelectrophoresis  on 
cellulose  acetate  could  be  used  routinely  to  determine  the  Gc  component 
of  the  serum.  This  test  proved  to  be  easy  to  perform,  accurate,  repro- 
ducible, and  economical.  This  experiment  confirmed  that  the  Gc  system 
was  under  genetic  control  and  could  be  used  to  help  establish  the 
parentage  of  a  child. 

The  verification  tests  by  Hirschfeld  could  be  used  to  eliminate  any 
genetic  variation  due  to  rare  Gc  types. 

The  data  was  not  conclusive  in  determining  the  gene  frequencies  of 
the  Negro  and  Caucasian  of  Anglo-Saxon  descent  in  the  midwestern 
United  States  region  because  the  number  of  tested  individuals  was  too 
small.  In  calculating  the  data,  the  gene  frequencies  of  Beam  and  Cleve 
were  used. 

Quantitative  Measures  of  In  Vitro  Cell  Mobility  by  Use  of  a  Pattern 
Recognition  Computer.  Georges  Barski,  James  W.  Butler,  and  Robert 
J.  Thomas,  DePauw  University. — The  purpose  of  these  researches  is  to 
find  a  quantitative  measure  of  cell  mobility,  in  vitro,  which  takes  account 
of  the  changes  in  the  shape  of  the  cell  and  of  the  motion  of  the  interior 
parts,  while  ignoring  the  random  translation  and  rotation  of  the  cell  as 
a  whole;  and,  furthermore,  to  use  a  computer  to  automatically  obtain 
such  measure.  The  usefulness  of  such  a  measure  would  be  in  researches 
regarding  effects  on  mobility  of  such  things  as  temperature,  different 
concentrations  of  a  chemical,  different  chemicals,  different  amounts  and 
kinds  of  radiation,  and  to  compare  normal  with  abnormal  cells. 

The  general  procedure  is  to  take  motion  pictures  of  the  cell  and 
use  the  film  as  input  to  Chloe,  the  Argonne  National  Laboratory  pattern 
recognition  computer.  Chloe  repares  a  record  (on  magnetic  tape)  of 
the  shapes  it  sees  in  each  frame;  this  record  of  shapes  is  then  analyzed 
by  a  standard  general  purpose  computer.  The  program  used  for  this 
analysis  is  one  which  is  also  used  for  automatic  karyotyping  of  chromo- 
somes; it  computes  the  area,  centers  of  mass,  moment  of  inertia,  and 
other  higher  moments  of  the  shapes  (in  combinations  which  are  invariant 


166  Indiana  Academy  of  Science 

under  translation  and  rotation  in  the  plane).  Another  program  then 
analyzes  the  changes  in  these  quantities  from  frame  to  frame  and  ob- 
tains a  measure  of  the  motion  of  the  cell.  It  is  in  this  latter  area  that 
most  of  the  research  has  been  and  is  being  carried  out,  as  there  are 
many  ways  to  combine  and  use  the  information  available  on  the  moments.

12,  13)  stimulated  considerable  interest  in  the  nature  of  its  interactions 
with  protoplasmic  constituents  (2,  3,  6).  Using  a  combined  biochemical 
and  histochemical  approach,  Hopwood  (6)  demonstrated  qualitatively 
that  glutaraldehyde  fixation  introduced  blockable  carbonyl  groups  into 
tissue  protein  and  that  glutaraldehyde  and  formaldehyde  preserved  gly- 
cogen to  a  similar  degree.  However,  quantitative  studies  of  the  reactions 
of  glutaraldehyde  with  protoplasmic  constituents  are  limited.  Evidence 
that  glutaraldehyde  cross-links  polyamines  (including  proteins)  and  poly- 
hydroxy  compounds  (such  as  polysaccharides)  has  come  largely  from 
studies  conducted  by  the  tanning  industry   (2,  6). 

This  report  presents  evidence  that  cross-linking  of  free  amino 
groups  of  proteins  is  critical  to  glutaraldehyde  fixation  of  cytomem- 
branes, (extractability  of  membrane  lipids  is  unaffected  by  glutaralde- 
hyde) and  that  glutaraldehyde  reacts  with  small  molecules  such  as  free 
amino  acids  and  primary  amines.  Most  of  the  glutaraldehyde  bound  by 
tissue  appears  to  result  from  its  binding  to  small  molecules  and  to  large 
molecules  other  than  protein. 

Materials  and  Methods 

Glutaraldehyde.  Excised  onion  stem  and  isolated  cell  fractions  from 
bean  leaves,  onion  stem  and  mouse  liver  were  treated  with  2.5%  glutaral- 
dehyde (prepared  from  a  50%  stock  solution,  Fischer  Scientific,  Bio- 
logical Grade,  to  which  0.16  g/ml  of  activated  coconut  charcoal  was 
added  to  remove  impurities)  at  0  to  4°.  Unless  stated  otherwise,  glutaral- 
dehyde solutions  were  prepared  in  0.01  M  sodium  phosphate  buffer,  pH 
7.0  to  7.3. 

Determination  of  protein  and  nitrogen.  Total  protein  was  determined 
from  lyophilized  fractions  which  were  quick  frozen  in  liquid  nitrogen 
and  dried  to  constant  weight  over  calcium  chloride.  Tissue  was  pulverized 
to  a  fine  powder  using  a  mortar  and  pestle  and  a  weighed  aliquot  was 
extracted  exhaustively  with  hot  (90°)  0.1  N  sodium  hydroxide.  Insoluble 
material  was  removed  by  centrifugation,  the  supernatant  was  neutralized 
with  trichloroacetic  acid,  and  the  protein  was  precipitated  by  addition  of 
an  equal  volume  of  1  M  trichloroacetic  acid  (0  to  4°;  2  to  3  hr).  Protein

was  estimated  by  the  biuret  method  (5).  Nitrogen  was  determined  by- 
direct  Nesslerization  (7). 

Extraction  and  determination  of  lipids.  For  lipid  extraction,  about 
4  g  fresh  weight  of  tissue  (either  untreated  or  glutaraldehyde-fixed)  was 
frozen  in  liquid  nitrogen,  lyophilized  and  dried  as  above,  powdered  with 
a  mortar  and  pestle  and  transferred  to  microsoxhlet  extraction  thimbles. 
The  chloroform  extractable  lipids  were  removed  by  a  3  hr  extraction 
with  15  ml  of  chloroform.  Chloroform  was  evaporated  and  the  lipid  resi- 
due was  brought  to  constant  weight  over  calcium  chloride,  redissolved  in 
chloroform,  filtered  to  remove  insoluble  materials,  recovered  by  evapora- 
tion of  solvent  and  brought  to  constant  weight.  Final  weights  were  cor- 
rected for  losses  during  filtration.  To  obtain  the  residual  lipid  fraction, 
the  thimbles  from  the  chloroform  extraction  were  placed  in  acetylization 
flasks  with  15  ml  of  95%  methanol  and  refluxed  for  1  hr  over  a  90° 
water  bath.  Methanol  was  evaporated  over  a  steam  bath  and  water  was 
removed  by  transferring  the  samples  to  a  90  to  95°  oven.  After  drying 
to  constant  weight  over  calcium  chloride,  15  ml  diethyl  ether  were  added 
to  the  residue  followed  by  exhaustive  soxhlet  extraction  (12  hr).  The 
chloroform-soluble  residue  after  decantation  and  evaporation  of  the 
ether  was  taken  as  residual  lipid. 

Thin  layer  chromatography  of  phospholipids.  Approximately  5  mg 
of  lipid  in  chloroform  were  streaked  on  each  20  X  20  cm  plate  coated 
with  Silica  Gel  G.  Development  was  in  chloroform  :methanol:water 
(65:35:4  v/v).  Regions  containing  lipids  were  detected  by  exposing  the 
plates  to  iodine  vapors,  scraped  from  the  plates  and  digested  with  sul- 
furic acid  and  hydrogen  peroxide.  Phosphorous  content  of  the  digests  was 
determined  by  the  method  of  Fiske  and  Subbarow  (4). 

Electron  microscopy.  Portions  of  isolated  pellets  were  post-fixed  for 
1  to  24  hours  in  1  per  cent  buffered  osmium  tetroxide  (0.1  M  sodium  phos- 
phate, pH  7.2)  or  exposed  for  several  days  to  osmium  tetroxide  vapors. 
Subsequent  dehydration  and  embedding  was  as  described  previously  (10). 
Sections  were  viewed  with  a  Siemens  Elmiskop  I  or  Philips  EM  200 
electron  microscope.  Magnifications  are  approximate.

nization  medium  (0.5  M  sucrose;  0.1  M  sodium  phosphate,  pH  7.1;  1% 
dextran).  Various  fractions  including  nuclei  (Fig.  1),  mitochondria  (Fig. 
2),  Golgi  apparatus  (Fig.  3),  endoplasmic  reticulum  (Figs.  3  and  8) 
and  smooth  membranes,  including  plasma  membrane  (Fig.  4),  were  iso- 
lated from  onion  stem  and  other  plant  and  animal  tissues  in  the 
presence  of  glutaraldehyde.  These  cell  components  were  morphologically 
indistinguishable  from  organelles  fixed  in  vivo.  Nuclei  had  intact  outer 
membranes  and  organized  chromatin  (Figs.  1  and  8).  Mitochondria  were 
dense  and  unswollen  (Fig.  2).  In  the  absence  of  glutaraldehyde,  plant 
Golgi  apparatus  vesiculated  and  the  stacked  cisternae  separated.  With 
glutaraldehyde,  breakdown  of  both  Golgi  apparatus  (Fig.  3)  and  endo- 
plasmic reticulum  (Figs.  3  and  8)  was  retarded.  With  chloroplasts  iso- 
lated without  glutaraldehyde  (Fig.  5),  outer  membranes,  osmiophilic 
granules  and  stroma  (chloroplast  matrix)  were  missing  and  the  lamellae 
were  distorted  and  swollen.  With  the  addition  of  2.5%  glutaraldehyde  to 
the  homogenization  medium  (Fig.  6),  the  outer  membranes,  osmiophilic 
granules  and  lamellae  were  well  preserved  and  clearly  defined.  The 
stroma  was  retained  in  the  uniformly  dense  aspect  characteristic  of 
chloroplasts  fixed  in  vivo. 

To  illustrate  a  similar  effect  of  glutaraldehyde  on  mammalian 
tissues,  Figure  8  shows  a  pellet  of  an  unfractionated  homogenate  of 
mouse  liver  prepared  in  the  presence  of  glutaraldehyde.  Organelles  in- 
cluding nuclei,  mitochondria,  microbodies  and  endoplasmic  reticulum 
were  obtained  with  morphological  characteristics  resembling  those  of 
whole,  fixed  tissues. 

Amount  of  glutaraldehyde  bound.  With  onion  stem  treated  with 
buffer  alone,  the  dry  weight  from  12  determinations  was  11.3±0.3% 
of  the  fresh  weight.  With  2.5%  buffered  glutaraldehyde  followed  by  four 
15  minute  buffer  rinses,  the  final  dry  weight  was  12.4±0.5%  of  the  fresh 
weight.  The  gain  in  dry  weight  due  to  glutaraldehyde  treatment  was 
1.1%  of  the  fresh  weight  or  about  10%  of  the  dry  weight.  The  increase 
in  dry  weight,  if  due  to  bound  glutaraldehyde,  would  amount  to  110 
/xmoles  of  glutaraldehyde  per  g  fresh  weight. 

Reaction  of  glutaraldehyde  with  lipids  and  proteins.  Total  lipid  ex- 
tracted by  chloroform-methanol-ether  consisted  of  about  40%  phospho- 
lipid and  60%  neutral  lipid  and  was  unchanged  by  glutaraldehyde  treat- 
ment of  the  tissue  (6.1%  of  the  dry  weight)  as  shown  by  data  of  Table  1. 
In  contrast,  total  protein  extracted  by  0.1  N  sodium  hydroxide  declined 
from  14%  of  the  dry  weight  (in  untreated  controls)  to  3.5%  of  the  dry 
weight  after  glutaraldehyde  treatment.  These  data  demonstrate  that  75% 
of  the  protein  was  sufficiently  cross  linked  to  prevent  extraction  into 
alkali.  Total  nitrogen  was  unchanged  at  3.2%  of  the  dry  weight. 

When  glutaraldehyde  was  added  to  protein  in  solution  (Fig.  9),  the 
bulk  of  the  protein  was  rendered  insoluble  with  a  reaction  half-time  of 
approximately  7  min.  As  with  whole  tissue,  about  75%  of  the  protein 
was  sufficiently  cross-linked  to  become  insoluble  in  0.1  N  sodium  hy- 
droxide following  glutaraldehyde  treatment.

Although  lipid  extractability  was  unchanged  by  glutaraldehyde 
treatment  (Table  1),  it  was  of  interest  to  consider  the  possibility  that 
certain  lipids  might  react  with  glutaraldehyde  and  yet  remain  lipid  solu- 
ble and  be  extracted  into  the  chloroform-soluble  fraction.  To  test  this 
possibility,  the  phospholipid  fraction  was  separated  by  thin  layer  chroma- 
tography into  low  Rf  phospholipids  (glyco-  and  sulfolipids),  lecithin 
(phosphatidylcholines),  ethanolamine  phospholipids  (phosphatidylethanol- 
amines)  and  two  phospholipid  fractions  containing  serine  (phosphatidyl- 
serines).  As  shown  by  data  of  Table  2,  lecithin  accounted  for  about  30% 
of  the  total  lipid  phosphorous  and  was  unchanged  by  glutaraldehyde 
treatment.  In  contrast,  the  amino  phospholipids  (those  containing  serine 
and  ethanolamine)  were  greatly  reduced  in  amount  at  positions  corre- 
sponding to  their  characteristic  Rf's  on  the  thin  layer  plates.  Recovery 
of  serine  phospholipids  was  35%  and  recovery  of  ethanolamine  phospho- 
lipids was  66%  in  contrast  to  95%  recovery  for  lecithin.  An  apparent 
increase  in  low  Rf  phospholipids  following  glutaraldehyde  treatment 
approximately  compensated  for  the  decrease  in  ethanolamine  and  serine 
phospholipids.  Total  recovery  of  lipid  phosphorus  was  94%  of  that  of 
unfixed  control  tissue. 

Reaction  of  glutaraldehyde  with  small  molecules.  Glutaraldehyde 
reacted  rapidly  with  the  primary  amino  groups  of  all  twenty  protein 
amino  acids  tested  (Table  3)  as  evidenced  by  loss  of  ninhydrin  reactivity. 
Paralleling  the  loss  of  chemical  reactivity  of  the  a-amino  group,  was  the

forming  the  yellow  coloration  given  by  all  amino  acids,  rapidly  pro- 
duced an  insoluble  precipitate  not  given  by  cysteine.  The  imino  acids, 
proline  and  hydroxyproline,  retained  ninhydrin  reactivity  following  glu- 
taraldehyde  treatment.  Proline  did  not  react. 

Of  the  nucleotide  bases  tested,  adenine  and  guanine  were  most  re- 
active with  the  formation  of  an  ultraviolet  light-absorbing  adduct  and

over  calcium  chloride,  the  lipids  were  extracted  with  chloroform- 
methanol-ether  from  one  half  of  each  pellet  as  described  for  whole  tissue. 
The  other  pellet  half  served  as  an  unextracted  control.  Prior  to  examina- 
tion in  the  electron  microscope,  both  pellets  were  stained  by  exposure  to 
osmium  tetroxide  vapor  and  embedded  directly  in  an  epon-araldite  mix- 
ture (10).  Figure  10  shows  a  portion  of  a  control  pellet  with  a  single 
dictyosome  and  a  segment  of  endoplasmic  reticulum.  With  both  cell  com- 
ponents, the  osmium  was  localized  largely  in  the  lumina  of  dictyosome 
cistemae  and  with  both  the  lumina  and  ribosomes  of  the  endoplasmic 
reticulum. 

In  the  extracted  pellet  (Fig.  11),  the  appearance  of  the  membrane 
was  similar  to  that  of  the  unextracted  controls  except  that  the  dictyo- 
somes  and  endoplasmic  reticulum  were  more  clearly  denned.  It  is  clear 
that  chloroform  extraction  of  lipids  did  not  alter  the  form  of  glutaralde- 
hyde-stabilized  dictyosomes  and  endoplasmic  reticulum,  and  that  the 
reactions  of  glutaraldehyde  with  protein  of  the  membrane  were  appar- 
ently sufficient  to  stabilize  the  form  of  the  organelle  as  viewed  in  the 
electron  microscope. 

Binding  of  small  molecules  to  membranes  in  homogenates.  Since 
glutaraldehyde  is  a  dialdehyde,  it  was  possible  that  reactive  small  mole- 
cules were  bound  to  cytomembranes  through  reaction  of  the  second  alde- 
hyde to  reactive  groups  on  large  molecules.  To  test  this  possibility,  radio- 
active metabolites  were  thoroughly  mixed  with  homogenized  onion  stem

(same  medium  as  for  organelle  isolation)  after  which  glutaraldehyde  was 
added  to  a  final  concentration  of  2.5%.  After  30  minutes  at  0  to  4°, 
the  homogenates  were  pelleted  at  12,000  g  for  30  min  and  washed  with 
distilled  water  through  several  resuspension-centrifugation  cycles  until 
constant  specific  activity  was  achieved.  With  C14-acetate,  a  molecule  not 
expected  to  react  with  glutaraldehyde,  the  level  of  radioactivity  in  the 
homogenate  was  1.8  m/anoles/^mole/mg  N.  Choline  gave  a  similar  value 
which  suggested  little  or  no  binding.  The  value  for  C14-uridine,  although 
obtained  from  mung  bean  stem  homogenates  rather  than  onion,  was 
sufficiently  low  to  suggest  little  or  no  binding.  Radioactivity  from  C14- 
glucose  bound  to  the  12,000  g  pellet  was  about  3  times  that  of  acetate 
showing  a  small  but  significant  reactivity  of  glutaraldehyde  with  a  sugar. 
Of  the  compounds  tested,  leucine  was  most  reactive,  binding  at  5  times 
the  amount  of  glucose.  In  competition  experiments,  it  was  found  that  the 
level  of  radioactive  leucine  bound  to  components  of  the  homogenates  was 
little  influenced  by  a  100-fold  excess  of  unlabeled  leucine. 

Loss  of  enzymatic  activity.  Typical  denaturation  kinetics  are  shown 
in  Figure  12  for  the  enzyme  CDP-choline-cytidyl  transferase  of  onion 
stem.  This  enzyme  catalyzes  the  formation  of  CDP-choline,  an  inter- 
mediate in  the  biosynthesis  of  lecithin,  from  phosphorylcholine  (P- 
choline)  and  cytidine  triphosphate  (CTP).

Discussion 


Although  glutaraldehyde  provides  superior  structural  preservation 
for  electron  microscopy  (1,  9,  14,  16),  its  use  in  organelle  stabilization 
or  in  metabolic  studies  may  modify  enzymatic  activity.  Loss  of  enzymatic 
activity  is  generally  associated  with  protein  cross-linking  by  glutaralde- 
hyde (3).  Examples  of  losses  of  enzymatic  activity  are  given  by  Hop- 
wood  (6),  Sabatini  et  al.  (14),  Barrnett  (1)  and  in  Figure  12.  Not  all 
enzymatic  activities  decline  following  treatment  with  glutaraldehyde. 
Some  activities  appear  to  be  unchanged  (15),  and  De  Jong  et  al.  (3) 
have  reported  activation  by  glutaraldehyde  of  an  acid  phosphatase  of 
nuclei  in  cultured  plant  cells.  Preliminary  results  indicate  an  activation 
of  a  CTPase  of  dictyosomes  isolated  from  onion  stem  following  treat- 
ment  of  homogenates   with   glutaraldehyde    (unpublished   observations). 

For  a  fixative  to  be  of  general  use  in  preparing  tissues  or  organelles 
for  chemical  analysis,  the  chemical  moiety  under  study  must  remain  un- 
modified. With  onion  stem,  lipids  are  recovered  quantitatively  after  glu- 
taraldehyde stabilization  and  the  phospholipid  lecithin  appears  to  be  un- 
changed. The  lipid  content  after  treatment  appears  to  reflect  the  lipid 
content  before  fixation.  Glutaraldehyde-stabilized  dictyosome  prepara- 
tions from  onion  stem  contain  50  to  60%  protein,  20  to  30%  phospholi- 
pids (rich  in  lecithin)  with  the  remainder  consisting  mostly  of  sterols 
and  neutral  lipids  (12). 

Studies  of  Park  et  al.  (13)  suggest  that  quantum  conversion  and 
electron  transport  in  photosynthesis  takes  place  within  the  rigid  frame- 
work of  glutaraldehyde-stabilized  plastids  and  that  these  processes  do 
not  require  conformational  changes  in  proteins.  They  showed  that  chloro- 
plasts  isolated  from  leaves  previously  fixed  in  6%  glutaraldehyde  retain 
optical  rotatory  dispersion  activity  and  absorption  spectra  of  unfixed 
chloroplasts  and  the  capability  of  limited  photochemical  activity.  Ferri- 
cyanide-Hill  activity  measured  by  02  evolution  or  indophenol  reduction 
was  25%  of  that  of  unfixed  chloroplasts.  The  oxygen  evolution  was  light 
dependent  and  sensitive  to  various  photosynthetic  inhibitors. 

That  the  morphological  integrity  of  glutaraldehyde-treated  organ- 
elles is  maintained  after  lipid  extraction  suggests  that  the  cross-linked 
protein  framework  of  the  organelle  is  the  critical  feature  of  glutaralde- 
hyde stabilization.  Golgi  apparatus  fractions  containing  small  fragments 
of  endoplasmic  reticulum  when  isolated  by  glutaraldehyde  stabilization 
showed  little  or  no  morphological  response  to  changes  in  osmotic  environ- 
ment. They  maintained  their  in  vivo  shapes  even  after  freeze  drying 
(Fig.  10)  or  freeze  diying  followed  by  extraction  of  total  lipids  using 
chloroform-methanol-ether  (Fig.  11).  Except  for  slight  increases  in 
osmium  deposition  after  lipid  extraction  such  preparations  were  indis- 
tinguishable from  each  other. 

Associated  with  the  reaction  of  glutaraldehyde  with  tissue,  tissue 
homogenates  or  isolated  cell  fractions  is  a  yellow  coloration  which  in- 
creases in  intensity  for  about  1  hour  after  addition  of  glutaraldehyde  at 
0  to  4°C.  Various  protein,  amino  acid  or  amine  solutions  treated  with 


Cell  Biology  179 

glutaraldehyde  assume  a  similar  color.  The  color  is  probably  due  to  the 
formation  of  Schiff  bases,  which  in  proteins  would  be  with  basic  amino 
acids.  Cystine  which  consists  of  two  cysteine  residues  linked  by  a  di- 
sulfide bond  did  not  precipitate  with  glutaraldehyde  as  did  cysteine.  This 
is  evidence  for  a  reaction  of  glutaraldehyde  with  the  free  sulfhydryl 
group  of  cysteine.  The  imino  acids  proline  and  hydroxyproline  contain  an 
amino  group  in  the  ring  which  is  apparently  unreactive  with  glutaralde- 
hyde. Hydroxyproline  appeared  to  react  slowly  with  glutaraldehyde  pos- 
sibly through  an  involvement  of  the  hydroxyl  group. 

Being  a  dialdehyde,  glutaraldehyde  is  capable  of  forming  cross- 
linking  bridges  in  proteins  involving  both  of  the  aldehyde  groups,  or 
under  certain  circumstances  only  one  of  the  aldehyde  groups  may  react 
with  protein.  Hopwood  (6)  demonstrated  qualitatively  that  free  carbonyl 
groups  are  introduced  into  proteins  following  reaction  with  glutaralde- 
hyde. The  free  aldehyde  could  then  react  with  other  cell  components  in- 
cluding free  amino  acids.  That  this  type  of  reaction  occurs  is  shown  by 
data  of  Table  4.  Radioactive  leucine  added  to  total  homogenates  of 
onion  stem  cross-links  to  organelles  sedimenting  at  12,000  g.  This  bind- 
ing is  apparently  nonspecific  and  in  competition  with  a  variety  of  re- 
active molecules  since  addition  of  excess  unlabeled  leucine  had  little  effect 
on  the  amount  of  labeled  leucine  bound  by  the  organelles.  Other  metab- 
olites including  choline,  acetate  and  uridine  are  not  bound  significantly. 
Glucose  is  bound  to  the  organelle  fraction,  presumably  via  cross-linking 
reactions  involving  the  free  hydroxyls,  at  a  level  1/10  that  of  leucine. 

These  results  show  that  glutaraldehyde  fixation  of  tissues  or  or- 
ganelle fractions  incubated  with  radioactive  metabolites  may  lead  to  non- 
specific binding  of  the  metabolites  via  the  cross-linking  reactions.  This 
possibility  must  be  taken  into  account  in  autoradiographic  or  biochemical 
studies  involving  radioactive  metabolites  and  especially  with  amino 
acids  when  supplied  in  conjunction  with  glutaraldehyde   stabilization.

To  summarize  our  findings,  calculations  of  the  distribution  of  po- 
tential glutaraldehyde  binding  sites  among  various  cell  constituents  is 
provided  in  Table  5.  From  the  dry  weight  changes  associated  with  re- 
action with  glutaraldehyde,  approximately  110  /mioles  of  glutaraldehyde 
are  bound  per  g  fresh  weight  of  onion  stem.  Of  this  110  ^moles,  less 
than  15  might  be  expected  to  bind  with  protein  on  the  basis  of  lysine 
and  cysteine  content.  Other  basic  or  hydroxy  amino  acids  may  react  with 
glutaraldehyde  but  evidence  presented  here  and  elsewhere  (2)  suggests 
the  a-amino  group  of  lysine  and  the  j3-SH  group  of  cysteine  as  poten- 
tially the  most  reactive  groups  in  the  interiors  of  protein  chains  (pre- 
sumably the  N-terminal  residue  would  also  be  available  for  reaction  with 
glutaraldehyde).  The  potential  contribution  of  nucleic  acid  to  the  amount 
of  glutaraldehyde  bound  in  onion  stem  is  probably  less  than  2  ^moles  due 
to  the  small  amounts  of  nucleic  acid  present.  Adenine  and  guanine  (A  + 
G)  are  considerably  more  reactive  in  solution  as  the  free  base  than 
either  uridine  or  cytidine  (U  +  C).  Amino  lipids  react  with  glutaralde- 
hyde but  represent  only  25%  of  the  lipid  phosphorus  and  therefore  ac- 
count for  less  than  1  ^mole  of  the  total  glutaraldehyde  bound.  The  largest 
proportion  of  glutaraldehyde  bound  to  amino  groups  would  be  to  free 
amino  acids  and  other  small  molecules  containing  primary  amines.  As- 
suming that  80%  of  the  nonprotein  nitrogen  consists  of  amino  nitrogen 
(8),  this  class  of  molecules  could  account  for  up  to  55  ^moles  of  glutaral- 
dehyde per  g  fresh  weight  or  approximately  50%  of  the  total  glutaral- 
dehyde bound  by  the  tissue. 

We  have  no  estimate  of  the  amount  of  glutaraldehyde  bound  to  cell 
wall,  storage  polysaccharides  and  small  molecules  such  as  sugars  or 
alcohols.  Assuming  maximal  binding  to  amines,  this  fraction  would  repre- 
sent about  37  /rnioles  of  the  110  ^moles  total.  However,  it  appears  that 
under  usual  conditions  of  fixation  no  more  than  75%   of  the  available

sites  react  with  glutaraldehyde  (Fig.  9,  Table  2  and  estimates  from  re- 
action of  amino  acids  and  nucleic  acids  in  solution).  If  75%  is  used  as  the 
extent  of  reaction,  less  than  half  the  bound  glutaraldehyde  is  accounted 
for  by  reaction  with  amino  and  sulfhydryl  groups  (both  as  polymers  or 
small  molecules).  Thus,  binding  of  glutaraldehyde  to  cell  wall  and  other 
polyhydroxycompounds  might  be  more  extensive  than  the  37  /mioles/g 
fresh  weight  estimated  and,  in  plant  tissues,  might  account  for  binding 
equal  in  magnitude  to  that  by  primary  amines. 

Summary 

Chemical  evidence  suggests  that  glutaraldehyde  stabilization  of  cyto- 
membranes  occurs  primarily  by  cross-linking  free  amino  groups  of 
adjacent  polypeptide  chains.  Hydroxy  1  and  sulfhydryl  groups  may  also 
contribute  to  the  cross  linking.  However,  90%  or  more  of  the  total 
lipid  of  glutaraldehyde  treated  tissue  is  recovered  by  solvent  extraction. 
The  bulk  of  the  glutaraldehyde  bound  by  tissue  appears  to  be  the  result 
of  its  binding  to  small  molecules  and  to  large  molecules  other  than  pro- 
tein. Cross-linking  of  protein,  however,  appears  critical  to  glutaralde- 
hyde fixation  of  cytomembranes.

The  liver  continuously  secretes  triglycerides  and  cholesterol 
into  the  circulation  in  the  form  of  very  low  density  lipoproteins  (6).  The 
successful  isolation  of  the  various  components  of  the  secretory  system 
(endoplasmic  reticulum,  Golgi  apparatus  and  plasma  membrane)  from 
rat  liver  (7)  provides  new  approaches  to  the  identification  and  characteri- 
zation of  these  structures.  This  report  describes  the  procedure  for  the 
isolation  of  plasma  membrane  from  rat  liver  adopted  from  those  of 
Neville  (8)  and  Emmelot  et  al.  (4).  The  rates  at  which  these  plasma 
membrane  fractions  hydrolyze  the  mono-,  di-  and  triphosphates  of  adeno- 
sine are  compared  with  those  of  other  components  of  the  rat  liver  secre- 
tory system. 

Materials  and  Methods 

Isolation  of  plasma  membrane.  Male  rates,  200  to  300  g  (50  days 
old),  purchased  from  the  Holtzman  Company,  421  Holtzman  Road,  Madi- 
son, Wisconsin,  were  anesthetized  by  intraperitoneal  injections  of  0.5  to 
1  ml  pentobarbital  solution  (Abbott  Laboratories  Nembutal,  20  mg/ml). 
Each  liver  was  drained  of  blood,  minced  finely  and  homogenized  in  5 
to  10  ml  1  mM  sodium  bicarbonate  using  a  very  loose  fitting  Potter- 
Elvejheim  all-glass  tissue  homogenizer  (30  sec  at  1,000  rpm).  The 
homogenate  was  mixed  with  300  ml  of  1  mM  sodium  bicarbonate  and 
stirred  for  4  min,  after  which  the  suspension  was  filtered  through  a  single 
layer  of  premoistened  (with  bicarbonate)  cheesecloth  followed  by  a  second 
filtration  through  two  layers  of  premoistened  cheesecloth.  The  filtered 
homogenate  was  then  centrifuged  for  10  min  at  3,500  rpm  (about  1,500  g) 
using  50  ml  centrifuge  tubes  and  an  angle  rotor  (Servall  SS-34).  The 
supernatant  was  discarded  and  the  pellet  was  resuspended  in  80  ml 
1  mM  bicarbonate.  The  1,500  g  centrifugation-resuspension  cycles  were 
continued  until  a  clear  supernatant  was  obtained  (usually  3  to  4  times). 

The  final  washed  pellets  were  combined  in  1  mM  bicarbonate  (total 
volume  of  3  ml)  and  9  ml  of  sucrose  (density  1.3)  was  added  slowly  (by 
drops)  with  constant  stirring.  The  following  gradient  was  layered  over 
the  plasma  membrane  suspension:  5  ml  sucrose  density  1.20;  8  ml  su- 
crose density  1.18;  5  ml  sucrose  density  1.16;  4  ml  sucrose  density  1.14. 
The  gradient  was  then  centrifuged  for  75  min  at  24,000  rpm  (SW  25 
rotor,  Spinco  Model  L  Ultracentrifuge).  Plasma  membrane  was  collected 
from  the  1.16-1.18  density  interface.

Methods  for  obtaining  Golgi  apparatus  and  endoplasmic  reticulum 
fractions  will  be  described  in  detail  elsewhere.  These  fractions  were  rela-

containing  66  mM  NaCl,  33  mM  KC1,  5  mM  MgCl2  and  25  mM  Tris 
(pH  7.4).  The  corresponding  medium  for  the  Mg3  — ATPase  (EC 
3.6.1.4)  contained  100  mM  KC1  and  no  NaCl  according  to  the  procedure 
of  Emmelot  and  Bos  (3).  Protein  was  determined  by  the  Lowry  procedure 
(5).  The  complete  reaction  mixtures  contained  approximately  0.1  mg 
protein. 

Electron  microscopy.  Samples  of  isolated  fractions  were  prepared 
for  electron  microscopy  by  fixation  in  2%  osmium  tetroxide  buffered  to 
pH  7.1  with  sodium  phosphate  (12  hrs,  4°)  followed  by  dehydration  and 
embedding  in  an  Epon-Araldite  plastic  mixture.  Negative  staining  of  the 
unfixed  plasma  membrane  fractions  was  done  on  carbon-stabilized, 
collodion-coated  grids  by  first  resuspending  a  portion  of  the  pellet  in 
water  followed  by  mixing  the  suspension  with  an  equal  volume  of  2% 
phosphotungstate  (PTA)  neutralized  with  potassium  hydroxide  to  pH 
6.8.   Specimens  were  observed  and  photographed  using  a  Philips  EM/ 200. 

Results  and  Discussion 

Yield  and  purity  of  membranes.  The  yield  of  plasma  membrane  was 
1  to  4  mg  protein  from  10  g  fresh  weight  of  liver.  A  20-fold  enrichment 
of  5'-nucleotidase  and  a  50-fold  enrichment  of  Na  + -activated  ATPase 
relative  to  the  total  homogenate  was  obtained  (Tables  1  and  2).  The 
final  pellets  consisted  of  a  pinkish-white  layer  of  plasma  membrane  over 
a  small  layer  of  mitochondria.  Based  on  estimates  of  succinic  dehydro- 
genase (9),  the  activity  of  the  plasma  membrane  fraction  was  25%  that 
of  purified  mitochondria.  Glucose-6-phosphatase  activity  was  25%  that 
of  purified  endoplasmic  reticulum.  Perhaps  no  more  than  50%  of  the 
final  pellet  was  plasma  membrane. 

Electron  microscopy.  Samples  of  preparations  taken  for  electron 
microscopy  contained  vesicles  of  many  sizes  (Fig.  1).  Occasionally  a 
desmosome,  a  feature  of  the  plasma  membrane,  was  observed.  Granules 
suggestive  of  ribosomes  were  not  observed  but  mitochondria  and 
mitochondrial  fragments  were  prevalent.

After  staining  with  phosphotungstic  acid  (PTA),  the  collapsed  mem- 
branes were  embedded  in  a  thin  amorphous  film  of  stain.  Most  of  the 
membranes  examined  showed  a  fine  granular  structure  in  surface  view 
with  smooth  edges.  Occasionally,  membrane  margins  exhibited  globular 
knobs  with  an  approximate  diameter  of  50  or  60  A  (Fig.  2).  These  knobs 
have  been  described  as  characteristic  of  certain  regions  of  the  plasma 
membrane  (1,  2),  probably  the  microvilli  extruding  into  the  bile  spaces 
(Benedetti  and  Emmelot,  unpublished).  In  addition,  a  hexagonal  array 
of  subunits  was  observed  in  certain  membrane  sheets  (Fig.  3)  as  pre- 
viously reported  by  Benedetti  and  Emmelot  (1).  The  hexagonal  subunit 
patterns  were  prevalent  in  preparations  containing  tight  junctions   (2). 

Sodium-potassium  activated  ATPase.  The  specific  activities  of  the 
Mga+-ATPase  and  (Na  +  -K+)-ATPase  of  freshly  prepared  plasma  mem- 
brane (Table  1)  showed  considerable  variation  from  preparation  to 
preparation.  This  is  consistent  with  reports  for  other  membrane  ATPase 
systems  (3).  The  (Na+-K+) -ATPase  is  the  Na  + -mediated  increase  of 
inorganic  phosphate  released  from  ATP  over  that  observed  in  the  absence 
of  Na+  with  adjustment  of  [K+]  to  maintain  osmolarity  (Table  1). 
Sodium  ions  increased  the  inorganic  phosphate  released  from  ATP  in  the 
presence  of  potassium  ions  by  most  plasma  membrane  preparations  to 
about  170%  that  obtained  in  the  absence  of  sodium  ions.  Results  with 
Golgi  apparatus  and  endoplasmic  reticulum  fractions  were  variable  and 
inconclusive. 

5' '-Nucleotidase.  As  summarized  in  Table  2,  the  5'nucleotidase 
(AMPase)  activities  of  the  plasma  membrane  fractions  were  significantly 
higher  than  either  endoplasmic  reticulum  or  Golgi  apparatus.  This 
activity  appears  to  be  localized  as  an  intrinsic  constituent  of  the  liver 
plasma  membrane  and  serves  as  a  convenient  measure  of  plasma  mem- 
brane contamination  of  these  cell  fractions. 

ADPase.  In  contrast  to  previous  reports  of  Emmelot  and  Bos  (3), 
plasma  membrane  fractions  obtained  by  our  procedures  showed  a  low 
level  of  ADPase  activity  (Table  2).  It  has  not  been  verified  that  this 
increase  in  inorganic  phosphorus  is  due  to  a  genuine  ADPase.

Summary 

A  plasma  membrane-rich  cell  fraction  isolated  from  rat  liver  was 
shown  to  contain  both  a  Mg'J+ — ATPase  and  a  sodium-potassium-activated 
ATPase.  The  fraction  was  characterized  by  a  high  5'-nucleotidase  activ- 
ity with  AMP  as  substrate.  This  activity  was  low  or  absent  in  isolated 
Golgi  apparatus  and  endoplasmic  reticulum  fractions.  The  absence  of 
AMPase  in  other  cytomembrane  fractions  and  the  ease  and  unambiguity 
of  its  estimation  makes  AMPase  a  useful  marker  enzyme  for  plasma 
membrane.

Membranifibrils  on  Cristae  and  Grana  Membranes1

Abstract 

Mitochondria  cristae  show  a  linear  arrangement  of  the  90A  headpieces 
on  the  membrane  surface  when  observed  by  negative  staining.  Treatment 
with  Triton  releases  fibrous  structures  of  70A  diameter  to  which  the  90A 
headpieces  are  attached.  (J.  W.  Stiles,  Ph.D.  thesis,  Purdue  University, 
1969)  These  fibers  have  been  purified  and  contain  15%  lipid  and  very  little 
cytochrome.  Extraction  of  the  membranifibril  with  acetone  leaves  a  30A 
diameter  fibrous,  insoluble  protein  which  may  be  the  basis  for  the  fibrous 
structure. 

Similar  linear  arrangements  of  particles  variously  referred  to  as 
quantosomes  or  chloroplast  Fi  have  been  observed  on  chloroplast  grana 
membranes.  Extraction  of  the  grana  with  triton  releases  fibrous  structures 
of  70A  diameter  to  which  100A  particles  are  attached.  We  propose  that  the 
basis  of  linear  organization  of  particles  on  the  surface  of  cristae  and  grana 
membranes  is  based  on  their  attachment  to  a  fibrillar  structure  in  the 
membrane  called  the  membranifibril. 

Introduction 

Globular  particles  have  been  demonstrated  on  the  surfaces  of  various 
biological  membranes.  The  membranes  of  mitochondrial  cristae  and  of 
chloroplast  grana  are  two  such  examples.  Spherical  90a  particles  are 
seen  projecting  on  stalks  from  the  surface  of  inner  mitochondrial  mem- 
branes when  observed  by  negative  staining  (3).  Oligomycin-insensitive 
ATPase  activity  has  been  shown  to  be  associated  with  these  particles 
(15).  Numerous  particles,  70-140A  in  diameter,  are  found  associated  with 
the  membranes  of  chloroplast  lamellae  when  viewed  by  negative  stain- 
ing. Some  of  these  particles  have  been  identified  as  carboxydismutase 
(8,  21).  Others  have  been  variously  associated  with  chloroplast  fraction  I 
protein,  ca  +  +-dependent  ATPase,  and  quantasomes    (1,  9,  14). 

The  regular  orientation  of  particles  on  the  surfaces  of  their  respec- 
tive membranes  suggests  that  a  discrete  substructure  may  be  responsible 
for  holding  particles  in  place.  Evidence  for  linear  substructure  in  mito- 
chondrial cristae  (18,  19)  and  chloroplast  grana  (1,  14,  16)  has  been 
previously  reported.  Evidence  has  also  been  presented  for  fibers  in 
plasma  membrane  (5).  Linear  elements  have  been  observed  in  cholate 
extracts  of  mitochondria,  but  have  not  been  interpreted  as  fibers  (10,  13). 
A  fibrillar  structure  which  may  be  the  basis  of  linear  organization  of 
particles  in  chloroplast  grana  and  mitochondrial  cristae  will  be  described 
in  this  paper.

Materials  and  Methods 


Beef  heart  mitochondria  prepared  according  to  the  method  of  Low 
and  Vallin  (12)  were  homogenized  in  0.25  M  sucrose  and  stored  at  — 20° C 
for  at  least  4  days  prior  to  preparation  of  electron  transport  particles 
(ETP).  Following  thawing,  the  mitochondria  were  homogenized  in  0.001 
M  Tris-HCl,  pH  7.4,  and  centrifuged  at  11,700  x  g.  The  pellet  was 
washed  4  times  in  this  manner  then  resuspended  in  the  buffer.  The 
suspension  was  sonicated  for  two  5-min.  periods  in  a  brine  bath  using  a 
Branson  probe  sonifier  at  maximal  output.  Heavy  beef  heart  mitochondria 
were  removed  by  centrifugation,  at  11,700  x  g.  The  supernatant  was 
then  centrifuged  at  78,000  x  g  for  30  min.  The  pellet  was  washed  and 
resuspended  in  0.001  M  Tris-HCl,  pH  7.4.  If  the  ETP  were  to  be  stored, 
the  preserving  medium  of  Hansen  and  Smith  (7)  was  used. 

To  ETP  suspended  in  buffer  at  a  protein  concentration  of  30  mg/ml 
was  added  aqueous  10%  Triton  X-114  to  give  a  final  concentration  of 
Triton  of  3%.  Following  mixing,  the  solution  was  cooled  in  ice  for  15 
min.  then  solid  KC1  was  added  to  a  final  concentration  of  0.2  M.  The  mix- 
ture was  incubated  for  30  min.  with  stirring.  Centrifugation  at  78,000 
x  g  for  30  min.  yielded  a  yellow  supernatant  which  was  further  purified 
by  dilution  with  an  equal  volume  of  0.001  M  Tris-HCl,  pH  7.4,  which  was 
0.2  M  in  KC1,  followed  by  centrifugation.  Ammonium  sulfate  fractiona- 
tion of  the  supernatant  was  achieved  by  the  addition  of  the  solid  salt  to 
25%  saturation.  Centrifugation  at  27,000  x  g  for  30  min.  resulted  in 
a  sinking  precipitate,  a  floating  precipitate,  and  a  straw-colored 
supernatant. 

Chloroplasts  prepared  from  spinach  leaves  were  obtained  by  the 
method  of  Crane  (2).  After  2  washings  with  0.05  M  Tricine,  pH  7.4, 
followed  by  centrifugation  at  8,720  x  g,  the  pellet  was  resuspended  in 
buffer  which  was  4%  in  Triton  X-100  and  incubated  for  30  min.  with 
occasional  stirring.  The  mixture  was  then  centrifuged  at  144,000  x  g 
for  1  hr.

Protein  was  assayed  by  the  modified  biuret  procedure  of  Yonetani 
(25).  Phospholipid  was  extracted  using  the  standard  Folch  procedure  (4) 
with  aqueous  0.74%  KC1  as  the  salt.  The  organic  layer  was  evaporated 
to  dryness  and  the  phospholipid  taken  up  in  10  ml  of  chloroform-methanol, 
2:1.  One  ml  of  this  was  combined  with  an  equal  amount  of  concentrated 
sulfuric  acid  and  heated  over  a  flame  until  the  solution  blackened.  Then 
2-3  drops  of  concentrated  hydrogen  peroxide  were  added  and  the  mixture 
boiled  again.  The  clarified  solution  was  then  tested  for  phosphate  by  the 
method  of  Lindberg  and  Ernster  (11).  Cytochromes  were  determined 
from  difference  spectra  recorded  with  a  Unicam  SP  800  recording  spec- 
trophotometer by  the  method  of  Williams  (24).  The  extinction  coefficients 
of  Vanneste   (23)  were  used. 

Samples  were  negatively  stained  with  either  1%  phosphotungstate 
at  pH  6.9  or  saturated  uranyl  acetate.  Microscopy  was  done  on  a  Philips 
EM  200  using  Kodak  Electron  Image  Plates. 

Sonication  to  release  membranifibrils  was  carried  out  with  a  high- 
power  sonicator  kindly  supplied  by  Quigley-Rochester  Scientific  Inc. 

Results  and  Discussion 

Examination  of  untreated  electron  transport  particles  by  negative 
staining  reveals  flattened  vesicles  from  the  surface  of  which  project  90A 
particles  (Fig.  1).  These  particles  are  visible  on  the  membrane  surface 
as  well  as  at  the  edges  of  the  vesicles.  In  this  latter  profile  view,  particles 
can  frequently  be  seen  attaching  to  the  membrane  edge  by  a  stalk.  Closer 
examination  of  Figure  1  suggests  that  the  white  rim  to  which  the 
particles  attach  at  the  edge  of  the  vesicle  might  be  a  discrete  structure 
rather  than  just  a  rolled  edge.  At  arrow  A  this  white  rim  is  seen  to 
extend  out  from  the  membrane  surface  as  a  linear  structure.  The  paral- 
lel array  of  lines  on  the  membrane  surface  (at  arrow  B)  also  suggests 
a  linear  substructure  associated  with  these  membranes. 

Treatment  of  ETP  with  Triton  X-114  releases  linear  structures  to 
which  the  90a  particles  are  attached.  Following  ammonium  sulfate 
fractionation,  a  purified  fraction  of  these  structures  was  obtained  (Fig.  2). 
The  central  strands  have  an  average  diameter  of  70 A.  The  90a  particles 
are  arranged  opposite  one  another  in  a  regular  fashion  along  the  central 
strand.  This  linear  structure  has  been  called  the  membranifibril  (17). 
Treatment  of  ETP  with  deoxycholate  and  KC1,  according  to  the  method  of 
Tzagoloff  et  al.  (22),  releases  linear  elements  which  resemble  the  mem- 
branifibril. Similar  structures  have  also  been  observed  following 
sonication  of  whole  beef  heart  mitochondria  (Fig.  3). 

Preliminary  chemical  analysis  of  the  purified  Triton-prepared  mem- 
branifibrils revealed  that  they  are  composed  mostly  of  protein.  Hence 
the  name  fibril  is  applicable.  Several  bands  were  observed  on  gel  electro- 
phoresis. The  membranifibrils  also  contain  a  small  amount  of  lipid,  about 
15%,  and  very  little  cytochrome.  The  preparation  shows  ATPase  activity. 
Initial  flavin  analysis  indicates  that  there  may  be  an  acid-extractable

flavin     associated     with     the     membraninbril     fraction.      The     chemical 
composition   of  the  mitochondrial  membranifibrils   is  found  in  Table   1. 

Kopaczyk  et  al.  (10)  have  isolated  a  rutamycin-sensitive  ATPase 
fraction  (P2)  by  cholate  and  ammonium  sulfate  treatment  of  inner  mito- 
chondrial membrane  which  resembles  our  membraninbril  fraction  both 
chemically  and  structurally.  Their  P2  fraction  showed  no  cytochrome  aa3 
and  low  levels  of  the  b  and  c  cytochromes.  The  lipid  content  of  their  frac- 
tion was  reported  as  10.7%.  The  fraction  showed  minimal  rutamycin- 
sensitive  ATPase  activity  in  the  absence  of  added  phospholipid.  Maximal 
activity  was  achieved  by  the  addition  of  1  mg  of  phospholipid  per  mg  of 
P2  preparation  to  the  assay  medium. 

Membranifibrils  are  clearly  evident  in  their  electron  micrographs  of 
the  rutamycin-sensitive  ATPase  (P2)  fraction.  However,  they  interpret 
these  structures  as  headpiece-stalk  sectors  projecting  exteriorly  from 
phospholipid  bilayers  or  coiled  phospholipid  micelles.  A  lipid-based  struc- 
ture hardly  seems  likely  considering  the  low  lipid  content  of  the  P2 
fraction  and  of  our  membranifibril  preparation. 

Extraction  of  the  membranifibril  with  acetone  or  chloroform-methanol 
leaves  a  30a  diameter  fibrous,  insoluble  protein  (Fig.  4).  This  fibrous 
protein  may  be  the  basis  of  membranifibril  structure. 

When  untreated  washed  and  lysed  chloroplasts  are  observed  by  nega- 
tive staining,  the  grana  membranes  are  seen  to  have  a  particulate  surface 
(Fig.  5).  These  particles  have  an  average  diameter  of  100a  and  appear 
to  be  aligned  in  rows  (indicated  by  arrow).  Treatment  of  the  chloroplast 
fragments  with  Triton  releases  fibrous  structures  very  similar  to  the 
mitochondrial  membranifibrils  (Fig.  6).  These  structures  are  collected  in 
the  144,000  x  g  supernatant  and  have  been  called  chloroplast  membrani- 
fibrils (20).  These  structures  consist  of  70a  diameter  strands  to  which 
the  100a  particles  are  attached.  Chemical  composition  and  enzymatic 
activity  of  the  chloroplast  membranifibrils  is  currently  under  investiga- 
tion. Structures  resembling  chloroplast  membranifibrils  have  been  seen 
following    sonication    of    intact    chloroplasts. 

It  is  proposed  that  the  membranifibril  is  the  basis  of  the  linear 
arrangement  of  particles  on  the  surface  of  mitochondrial  cristae  and 
chloroplast  grana  membranes  by  virtue  of  the  attachment  of  these 
particles  to  the  fibrillar  structure.  In  mitochondria,  such  a  structure 
would  correspond  to  the  basepieces  which  Green  has  proposed  as  the  site 
of  the  electron  transfer  chain  (6).  However,  since  the  membranifibril 
contains  very  little  cytochrome  it  is  unlikely  that  cytochrome  dependent 
electron  transport  function  is  associated  with  the  site  of  attachment  of 
the  90a  particles. 

Summary 

A  new  structural  element,  the  membranifibril,  was  isolated  from  the 
membranes  of  mitochondria  and  chloroplast  grana  by  Triton  treatment. 
Preliminary  investigation  of  the  chemical  composition  and  the  enzymatic 


196  Indiana  Academy  of  Science 

activity  of  these  fibrils  was  conducted.  It  was  proposed  that  the  mem- 
branifibrils  are  the  basis  of  the  linear  organization  of  the  particles  on 
these  membranes.

X-Ray  Diffraction  Study  of  Aqueous  Thallium   (III)  Chloride.    Richard 

M.  Lawrence,  Ball  State  University. — The  radial  distribution  function 
of  2.5  M  aqueous  thallium  (III)  chloride  having  a  mole  ratio  of  chloride 
ion  to  thallium  ion  of  4.3  was  calculated  from  x-ray  diffraction  data.  The 
radial  distribution  function  is  consistent  with  the  existence  of  the  tetra- 
chlorothallate  (III)  ion  as  the  dominate  ionic  species  in  the  solution. 
There  is  evidence  that  the  shape  of  the  TlCL-ion  is  that  of  a  distorted 
tetrahedron  with  each  chloride  ion  being  at  about  95°  from  two  others 
and  about  127°  from  a  third.  The  distortion  in  the  complex  ion  is  quali- 
tatively attributed  to  solvent  stabilization  effects.  There  is  no  evidence 
for  thallium-ion — water-molecule  contact  in  the  proposed  model  of  the 
tetrachlorothallate   (III)   ion. 

Studies  of  a  Cyanamide  Complex  of  Iron (II).  F.  J.  Holler  and  R.  D. 
Joyner,  Ball  State  University. — A  number  of  possible  ways  that  the 
cyanamide  unit  could  coordinate  with  a  metal  are  suggested.  These  pos- 
sibilities include  simple  ionic  and  molecular  complexes  as  well  as  bridge 
structures.  A  pentacyano-cynamide  complex  of  iron  (II)  has  been 
referred  to  in  analytical  studies  of  cyanamide,  but  no  previous  studies 
have  been  concerned  with  its  actual  preparation.  Optimum  conditions  for 
the  formation  of  this  complex  have  now  been  determined.  Additional 
studies  have  been  made  concerning  the  isolation  and  purification  of  the 
complex. 

Phthalocyaninogermanium(II)  and  Other  Phthalocyaninogermanium  Com- 
pounds. R.  L.  Stover  and  R.  D.  Joyner,  Ball  State  University. — Reac- 
tions of  germanium  compounds  of  the  form  RiGeCk-n  (R  =  phenyl, 
n  -butyl,  hydrogen;  n  =  0,  1,  2,  3,  4)  with  metal  free  phthalocyanine, 
sodium  phthalocyanine,  and  diiminoisoindoline  are  described.  Apparently 
phthalocyaninogermanium  compounds  are  not  formed  from  compounds  of 
the  type  R4GeCl4-.11  where  n>l.  The  reaction  of  phenyl  germanium 
hydride  with  metal-free  phthalocyanine  to  apparently  give  phthalocy- 
aninogermanium (II)   is  described. 

A   Kinetic   Study   of   the   Reaction   of   Phenyl   Isocyanate   with   Water. 

LeRoy  A.  McGrew  and  Stephen  C.  Robling,  Ball  State  University. — 
The  rate  of  the  reaction  of  phenyl  isocyanate  with  water  in  acetone  solu- 
tion was  followed  by  measuring  the  rate  of  carbon  dioxide  evolution.  In 
the  presence  of  excess  water  the  reaction  was  found  to  be  first  order  with 
respect  to  isocyanate  concentration.  The  pseudo-first  order  rate  constant 
was  found  to  be  5.5  X  103  sec.-1.  The  reaction  was  found  to  be  catalyzed 
by  tertiary  amine  bases.  Primary  amines  suppressed  the  normal  decom- 
position  by    reacting   with    the   isocyanate    in    a    fast   step    to    produce

N,N-diphenylurea.  This  urea  was  also  observed  to  be  the  only  product  of 
the  normal  reaction  with  water.  The  experimentally  determined  rate  law 
was  shown  to  be  consistent  with  a  proposed  mechanism. 

Organonitrile  Complexes  of  Rhenium  (I)  and  Manganese  (I).  Bruce  N. 
Storhoff,  Ball  State  University,  and  J.  R.  Doyle,  the  University  of 
Iowa. — Bromopentacarbonylrhenium(I)  reacts  with  acetonitrile,  propioni- 
trile,  acrylonitrile  and  benzonitrile  to  yield  complexes  of  the  stoichiometry 
Re(CO)3(RCN)2Br.  Bromopentacarbonylmanganese(I)  reacts,  in  an  anal- 
agous  manner,  with  acetonitrile  and  benzonitrile  to  yield  the  tricarbonyl 
complexes  Mn(CQ)3(RCN)2Br.  The  infrared  spectra  of  the  complexes 
suggest  octahedral  structures  with  the  two  nitriles  cis  to  each  other  and 
cis  to  the  bromine. 

Bromopentacarbonylmanganese(I)  reacts  with  acrylonitrile  and 
propionitrile  to  yield  complexes  of  the  stoichiometry  Mn(CO)3(RCN)Br 
which  are  suggested  to  be  halogen  bridged  dimers  on  the  basis  of  molecu- 
lar weight  and  infrared  studies.  J9i-/x-bromooctacarbonyldirhenium(I) 
reacts  with  acetonitrile  to  yield  cis-Re(CO)4(CH3CN)Br. 

Infrared  studies  indicate  that  for  each  complex  the  organonitriles 
are  attached  to  the  metals  through  the  pair  of  electrons  associated  with 
the  nitrogen.  Molecular  weight  studies  and  nuclear  magnetic  resonance 
studies  of  the  tricarbonyl  complexes,  M(CO)3(CN)2Br,  indicate  that  they 
dissociate  in  chloroform  solution  but  not  in  dimethylsulfoxide  solution. 

Replacement  reactions  indicate  that  the  nitriles  of  all  the  manga- 
nese (I)  and  rhenium  (I)  complexes  can  be  replaced  by  pyridine  and  sug- 
gest that  olefins  do  not  replace  the  nitriles. 

Use  of  Computers  in  Undergraduate  Physical  Chemistry.  Richard  F. 
Copeland,  Ball  State  University. — Computers  can  be  very  valuable  tools 
for  the  student  of  physical  chemistry,  but  for  most  students  the  junior  or 
senior  year  course  in  undergraduate  physical  chemistry  is  not  the  time  to 
begin  to  learn  computer  programming.  The  best  results  should  be 
obtained  by  a  program  integrating  the  use  of  computers  into  chemistry 
courses  beginning  with  the  freshman  course  in  general  chemistry. 
Instruction  at  the  freshman  level  may  be  in  either  a  special  course,  or, 
preferably,  incorporated  into  the  general  chemistry  laboratory  sequence. 
Analysis  of  data  using  library  programs  is  a  very  useful  asset,  but 
emphasis  should  be  on  the  student's  use  of  programming  to  solve  his 
individual  problems.  Simulation  of  complex  chemical  systems  involving 
large  numbers  of  variables  can  be  a  valuable  tool  in  instruction. 

Synthesis  and  Properties  of  [2.2.2] Bicyclooctyl  Enamines.  A.  G.  Cook 
and  T.  A.  Hecht,  Valparaiso  University. — Some  [2.2.2]bicyclooctyl 
enamines  have  been  synthesized  and  some  of  their  properties  investi- 
gated. The  ultraviolet  spectra  of  some  of  them  seems  to  be  indicative 
of  some  homoconjugation. 

Reduction  of  Selected  Enamines  with  Lithium  Aluminum  Hydride.   A.  G. 

Cook  and  D.  J.  Schultz,  Valparaiso  University. — It  has  been  observed 
that  certain  enamines  possess  structural  features  which  make  them  sus- 
ceptible to  reduction  by  lithium  aluminum  hydride.  These  features  will 
be  discussed.

Temperature  and  Moisture  Relationships  of  Green  County,  Indiana  Strip 
Mine  Areas.  R.  Michael  Dinkel  and  Fred  Rothwell,  Indiana  State 
University. — Temperature  and  moisture  are  physical  factors  which  must 
be  taken  into  consideration  when  one  considers  the  reclamation  of  strip- 
mined  land  by  means  of  forestation.  During  the  spring  and  summer  of 
1968,  temperature  and  moisture  readings  were  made  on  and  in  the 
vicinity  of  the  Green  County  spoil  bank  location.  These  were  measured 
periodically  and  data  was  compiled  in  order  to  determine  the  significance 
of  varying  temperature  and  moisture  relationships  on  the  viability  and 
growth  of  tree  seedlings  introduced  on  the  spoil  bank  and  coal-mine 
areas. 

Ecological  Site  Preference  and  Taxonomic  Differences  within  Two  Acer 
saccharum-Acer   nigrum   Complexes    Found     in     Parke     County,    Indiana. 

Alfred  G.  Craske,  Jr.,  Indiana  State  University. — A  study  was  con- 
ducted on  the  ecological  site  preferences  and  taxonomic  differences 
within  two  Acer  saccharum-Acer  nigrum  complexes  found  in  Parke 
County,  Indiana.  A  suitable  means  of  identification  was  determined  for 
the  two  species  based  on  leaf  characteristics.  A  significant  difference  was 
found  between  flood  plain  and  slope  and  flood  plain  and  upland  popula- 
tions based  on  leaf  morphology.  The  flood  plain  was  found  to  have  sig- 
nificantly higher  pH  and  phosphorus  values  and  significantly  less  canopy 
cover  than  those  values  for  slope  or  upland.  No  significant  differences 
were  found  between  slope  and  upland  for  the  ecological  parameters. 
Sugar  maple,  black  maple  and  the  intermediates  were  found  to  represent 
three  populations.  The  intermediate  population  represented  the  central 
portion  of  a  continuum  of  leaf  characters  running  from  black  maple  to 
sugar  maple.  Acer  nigrum  Michx.  f.  showed  a  definite  site  preference 
for  the  flood  plain.  Acer  saccharum  Marsh,  showed  a  definite  site  prefer- 
ence for  the  slope  and  upland.  It  would  thus  appear  that  the  character 
of  site  preference  would  be  valuable  for  identification  and  should  be 
incorporated  into  discriptions  of  the  two   species. 

Effects  of  Thermal  Discharge  on  the  Phytoplankton  and  Macroinverte- 
brates  of  the  Wabash  River.  Jerry  L.  Gerwig  and  Wm.  B.  Crankshaw, 
Ball  State  University. — The  effects  of  thermal  discharge  on  the  phyto- 
plankton and  macroinvertebrates  were  studied  on  the  Wabash  River  in 
Sullivan  County,  Indiana.  The  temperatures  recorded  in  the  normal  river 
water  ranged  between  72  and  78  degrees  F.  Temperatures  recorded  in 
the  heated-water  zone  varied  from  87  to  74  degrees  F.

Nineteen  genera  and  nine  families  of  green  algae  (Chlorophyceae), 
blue-green  algae  (Myxophyceae),  and  diatoms  (Bacillariophyceae)  con- 
stituted the  phytoplankton  population.  Green  algae  represented  95  to  97 
percent  of  the  algal  population,  blue-green  algae  represented  2  to  3  per- 
cent, and  diatoms  represented  1  to  2  percent  regardless  of  the  station  or 
the  average  number  of  organisms  per  liter  of  water.  The  invertebrates 
collected  were  mainly  various  insect  larvae  and  nymphs. 

Effects  of  Effluent  on  the  Fish  Population  of  Mill  Creek,  Rochester,  Indi- 
ana. Frederic  Morgan,  Ball  State  University. — This  is  a  report  of  pre- 
liminary data  showing  the  effect  of  city  and  light  industrial  effluent  on 
fish  life.  Mill  Creek  is  located  in  North-Central  Indiana.  It  begins  as 
the  overflow  of  Lake  Manitou  and  runs  approximately  five  miles  to  the 
Tippecanoe  River,  passing  through  the  city  of  Rochester. 

Fish  were  collected  from  eleven  stations:  four  sites  above  the  major 
sources  of  effluent,  three  sites  scattered  through  them,  and  four  sites 
below  them.  The  fish  were  collected  by  blocking  off  a  measured  segment 
(60  m)  of  the  stream  with  quarter-inch  knotted  minnow  seines  and 
making  two  sweeps  with  an  electric  seine.  At  the  eleven  sites,  production 
of  fish  varied  from  a  high  of  41.1  g/m2  at  station  number  four  above  the 
sources  of  effluent  to  zero  at  station  number  seven.  Downstream  in  the 
last  four  stations  the  fish  population  slowly  started  to  recover:  .03 
g/m2,  .05  g/m2,  .8  g/m2,  and  3.1  g/m2.  From  all  sites  we  removed  1166 
fish  representing  31  different  species.  The  number  of  species  per  site 
varied  from  nineteen  at  station  four  above  the  sources  of  effluent  to  zero 
at  station  seven.  A  recovery  was  noted  in  the  four  downstream  sites: 
3,  5,  7  and  11. 

During  the  past  twelve  months,  water  samples  were  taken  at  four 
sites  and  analyzed  for  D.O.,  temperature,  hydrogen  sulfide,  hardness, 
turbidity,  anionic  detergent,  total  phosphate,  nitrite,  nitrate,  ammonia 
and  pH. 

A  Study  of  Selected  Physiochemical  Properties  of  Two  Indiana  Main- 
Stream  Reservoirs.  Paul  T.  McKelvey  and  Charles  E.  Smith,  Jr.,  Ball 
State  University. — Selected  physiochemical  properties  of  Lake  Shafer  and 
Lake  Freeman,  two  shallow,  narrow  main-stream  reservoirs  near  Monti- 
cello,  Indiana,  were  determined  from  November,  1967,  through  June, 
1968.  Bi-monthly  sub-surface  samples  from  eight  stations,  four  on  each 
reservoir,  were  analyzed. 

These  reservoirs  were  found  to  have  certain  properties  resembling 
those  of  rivers,  e.g.,  width,  depth,  carbon  dioxide  concentration,  and  the 
absence  of  distinct  thermal  stratification.  Other  properties,  typical  of 
natural  lakes  and/or  large  reservoirs  were,  e.g.,  total  alkalinity,  dissolved 
oxygen,  nitrate,  pH,  and  sulfate.  Phosphate,  nitrite,  and  turbidity  values 
were  intermediate  between  those  of  rivers  and  natural  lakes  and/or  large 
reservoirs.  Total  alkalinity,  nitrate,  and  phosphate  cycles  were  also 
noted.

Lake  Shafer  and  Lake  Freeman  were  considered  eutrophic  based  on 
the  high  nutrient  levels,  especially  nitrate  and  phosphate,  present  in 
their  waters. 

Pattern  of  Mesic  Forest  Succession  at  the  Western  Border.   R.  O.  Petty, 

Wabash  College. — Data  and  analysis  are  presented  for  forest  stands 
which  depict  the  successional  trends  currently  underway  at  the  western 
extension  of  the  mesophytic  forest.  Emphasis  is  given  to  the  performance 
of  several  significant  species,  especially  Quercus  velutina,  Acer  saccharum 
and  Fagus  grandifolia.  A  model  of  successional  pattern  is  offered  to 
explain  the  several  cliseral  shifts  which  have  occurred  during  the  post- 
glacial period,  as  seen  in  palynology  and  in  the  phytosociology  of  west- 
central   Indiana. 

The  Effect  of  Inorganic  Sediment  on  Macroinvertebrate  and  Fish  Popula- 
tions of  a  Central  Indiana  Stream.  James  R.  Gammon,  DePauw  Univer- 
sity.— The  composition  and  density  of  populations  of  macroinvertebrates 
and  fish  were  studied  during  1967  and  1968  in  a  1.5  kilometer  section  of 
Deer  Creek  which  received  wastewater  from  a  crushed  limestone  quarry. 
Heavy  deposits  of  sediment  which  accumulated  during  1966  were  swept 
downstream  by  floods  during  late  1966  and  early  1967.  Little  sediment 
accumulated  in  pools  below  the  quarry  during  1967  because  of  unusually 
high  levels  of  stream  flow  throughout  the  year  and  because  the  quarry 
settling  ponds  were  dredged  regularly.  Nevertheless,  35  tons  of 
sediment  entered  the  stream  from  the  quarry  during  1967. 

The  standing  crop  of  fish  in  three  pools  downstream  from  the  quarry 
averaged  only  55%  of  those  in  two  pools  upstream  in  June  1967  (224 
Kg. /ha.  compared  to  417  Kg. /ha.).  Carpsuckers  and  gizzard  shad  were 
almost  completely  lacking  downstream,  while  carp,  redhorse  and  suckers 
were  reduced  in  numbers.  By  early  August  many  small  individuals  had 
migrated  into  the  pools  below  the  quarry  and  the  standing  crops  rose  to 
an  average  of  255  Kg./ha.  compared  to  362  Kg. /ha.  in  the  upstream  pools. 

The  quarry  settling  ponds  received  relatively  little  attention  follow- 
ing a  thorough  dredging  in  early  August  1967  and  became  completely 
filled  and,  therefore,  inoperative  by  late  fall  of  1967.  Heavy  concentra- 
tions of  stonedust  entered  Deer  Creek  throughout  1968  as  a  result.  By 
August  2,  1968  over  3300  tons  of  sediment  were  contributed  to  Deer 
Creek.  The  standing  crop  of  fish  in  June  1968  in  the  pools  below  averaged 
only  25%  of  those  above  (100  Kg./ha.  compared  to  400  Kg./ha.). 

The  macroinvertebrate  populations  in  several  riffles  above  and 
below  the  point  of  pollution  were  sampled  monthly  during  months  of 
stable  water  levels.  The  density  in  the  riffles  below  averaged  less  than 
50%  of  that  above.  All  orders,  families,  genera  and  species  seemed  to  be 
reduced  equally  in  abundance. 


The  Effect  of  Ground  Cover  on  the  Soil  Moisture 
Regime  in  a  Mixed  Mesophytic  Woods 

William  B.  Crankshaw,  Ball  State  University 

Abstract 

A  25-acre  mixed  mesophytic  woods  in  southwestern  Delaware  County 
was  used  to  study  the  effect  on  soil  moisture  regime  by  presence  or  absence 
of  ground  cover.  Four  sites  were  selected  within  the  woods,  a  Brookston 
silty  clay  loam  with  cover,  a  Brookston  silty  clay  loam  without  cover,  a 
Crosby  silty  clay  loam  with  cover  and  a  Crosby  silty  clay  loam  without 
cover.  Bouyoucos  soil  moisture  blocks  were  permanently  installed  at 
5,  10,  25,  and  50  cm.  depths  at  each  site.  Available  soil  moisture  was  moni- 
tored daily  for  a  period  of  thirteen  months.  Significant  differences  were 
found  in  rate  and  amount  of  loss  and  gain  of  available  moisture  content  at 
the  different  depths  for  both  soil  types  and  for  both  cover  situations.

A  25-acre  mixed  mesophytic  woods  in  southwestern  Delaware  County 
was  selected  to  study  the  effect  of  presence  or  absence  of  ground  cover 
on  soil  moisture.  Stewart  Woods,  the  area  chosen,  met  several  predeter- 
mined requisites.  These  requisites  included:  a  woods  bisected  by  a  fence, 
one  side  undisturbed,  the  other  side  lightly  grazed  and  also  at  least  two 
soil  types,  the  latter  oriented  perpendicular  to  the  fence  line.  These 
simple  specifications  quickly  excluded  most  of  the  wooded  areas  in  east 
central  Indiana. 

Methods 

Within  the  woods,  four  study  sites  were  established.  These  sites 
were  located  on  a  Brookston  silty  clay  loam  with  ground  cover,  a 
Brookston  silty  clay  loam  without  cover,  a  Crosby  silty  clay  loam  with 
cover  and  a  Crosby  without  cover.  Soil  moisture  and  soil  temperature 
probes  were  permanently  installed,  with  a  minimum  of  disturbance  to 
the  soil  structure  and  profile,  at  5,  10,  25,  and  50  cm.  depths  at  each  of 
the  four  sites.  Taylor  maximum-minimum  thermometers  and  rain  gages 
were  mounted  on  posts  one  meter  above  the  surface  at  each  site.  Air  and 
soil  temperatures,  precipitation  and  available  soil  moisture  were 
monitored   daily  for  thirteen   months. 

A  complete  census  was  made  of  the  24.25-acre  woods  by  species  and 
diameter.  The  phytosociological  parameters  of  relative  and  absolute 
density  and  basal  area  were  determined  as  well  as  importance  value 
(Table  1).  This  was  done  to  compare  the  grazed  and  ungrazed  areas  on 
the  basis  of  relative  importance  of  represented  species  and  to  evaluate 
the  difference  exerted  by  a  12-year  period  of  light  grazing  (one  calf  per  4 
acres). 

Sampling  of  ground  cover  was  accomplished  by  establishing  four 
one-meter  square  plots  near  each  site.  These  plots  were  located  10  meters

in  each  cardinal  direction  from  the  instrument  post.    All   shrubs,  tree 
reproduction  and  herbaceous  vegetation  were  tallied  by  species. 

Results  and  Discussion 

Little  significant  difference  was  noted  in  a  comparison  of  importance 
values  between  the  grazed  and  ungrazed  area.  The  grazed  portion  of  the 
woods  appeared  to  be  more  xeric  with  combined  importance  value  for 
oaks  and  hickories  of  53.1%  as  opposed  to  37.8%  for  the  ungrazed.  Note 
that  the  importance  for  the  ungrazed  portion  is  distributed  fairly  evenly 
between  five  species,  all  rather  mesic  in  their  requirements. 

Ground  cover  was  very  sparse  on  the  grazed  side  even  with  the 
minimal  grazing.  No  shrubs  were  tallied  and  very  few  forbs;  82.5% 
of  all  individuals  in  the  grazed  area  were  sedges  and  grasses. 

An  evaluation  of  the  soil  moisture  data  indicated  that  the  two  sites 
with  relatively  little  ground  cover  reached  field  capacity  earlier  than 
sites  with  cover  (Table  2).  This  difference  increased  with  depth,  i.e.,  the 
50  cm.  depth  showed  the  greatest  difference  in  moisture  content  between 
cover  and  non-cover.  The  25  and  50  cm.  depths,  once  they  achieved  field 
capacity,  remained  consistently  higher  in  available  moisture  content  than 
the  shallower  depths  not  only  during  the  growing  season,  but  all  year. 
Fluctuations  in  available  moisture  at  the  5  and  10  cm.  depths  were  very 
wide  during  the  summer  as  an  effect  of  convectional  rain  and  higher 
evaporation  rates.  The  moisture  regime  did  not  actually  stabilize  at  any 
depth  until  mid-March;  at  this  time  field  capacity  was  constant  and 
remained  so  until  June  and  July. 

Differences  in  soil  moisture  existed  between  the  two  soil  types  as 
well  as  in  the  presence  or  absence  of  cover.  Available  moisture  content 
began  decreasing  sooner  in  the  Crosby  than  in  the  Brookston  and 
dropped  to  15%  available  moisture  content  at  an  earlier  date.  The  differ- 
ence in  time  required  to  reach  15%  available  moisture  was  less  marked 
between  the  Crosby  and  Brookstone  as  the  soil  depth  increased.  Fall 
rains  caused  a  sharp  and  steady  increase  in  available  moisture  content 
at  the  50  cm.  level.  This  occurred  about  two  weeks  earlier  in  the  Crosby 
than  in  the  Brookstone.  Other  depths  in  both  soils  evidenced  an  increase 
but  with  the  increase  occurring  at  the  same  time  at  each  depth  and  at 
a  less  steady  rate  than  50  cm.  Though  the  penetration  was  better  on  the 
Crosby,  the  Brookston  had  in  general  a  higher  moisture  holding  capacity 
through  the  year. 

In  summary,  soil  moisture  reached  field  capacity  earlier  in  the 
grazed  portion  of  the  woods  on  the  Crosby  soil,  though  penetration  of 
moisture  was  greater  in  the  ungrazed.  Moisture  retention  was  greater 
at  all  four  depths  on  the  grazed  side,  particularly  on  the  Brookston  soil. 
Apparently,  grazing,  if  minimal  to  avoid  compaction,  has  a  favorable 
effect  on  the  soil  moisture  regime.

Detailed  Studies  of  Old-Growth  Forests  in  Versailles  State 
Park,  Indiana

Abstract 

Full  censuses  were  taken  for  17.46  and  6.44  acre  segments  of  two 
old-growth  upland  forests  located  in  Versailles  State  Park,  Ripley  County, 
Indiana.  The  stands  have  been  designated  as  Jackson's  and  Potzger's 
Woods,  respectively.  Transects  were  also  taken  in  the  slope  forests  of 
Jackson's  Woods  and  the  forest  composition  of  limestone  sinks  was 
studied. 

Jackson's  Woods  had  28  species  over  4  inches  and  33  species  over  2 
inches  dbh.  Density  per  acre  of  stems  over  4  inches  was  109  with  basal 
area  per  acre  of  112  ft.2  Beech  and  sugar  maple  ranked  first  and  second 
in  importance  value  with  32  and  25%,  respectively.  Tulip-poplar  followed 
with  14%,  and  dogwood  was  fourth  at  6.5%.  In  the  sinkholes,  beech  and 
sugar  maple  decreased  in  importance,  and  walnut,  elm  and  tulip-poplar 
increased  in  importance  in  larger  and  better  drained  sinks.  The  W-facing 
slope  forest  is  mixed  mesophytic;  oak  and  hickory  increases  on  exces- 
sively-drained NW  and  N-facing  slopes;  the  NE  and  E-facing  slopes  are 
watered    by    subsurface    seeps    and   have    forests    similar    to    floodplains. 

Potzger's  Woods  had  24  and  27  species  over  4  and  2  inches,  respec- 
tively. The  density  per  acre  was  121  with  a  basal  area  per  acre  of  117  ft.2 
Sugar  maple  and  beech  ranked  first  and  second  in  importance  with  39  and 
31%,  respectively;  walnut  was  third  at  5%  followed  by  white  ash  and 
black  gum.  Sugar  maple  was  exceedingly  dominant  in  the  smaller  size 
classes  in  both  stands.  The  present  full  tally  for  Potzger's  Woods  indicates 
that  sugar  maple  has  increased  in  stand  importance  since  1956,  most 
likely  at  the  expense   of  beech  which  has  declined  slightly   in   importance. 

The  stands  appear  to  be  transitional  between  the  mixed  mesophytic 
forests  of  extreme  southeastern  Indiana  and  the  beech-maple  types  of 
the  flat  uplands.  As  the  physiography  matures  the  woods  will  probably 
shift    to    a    more    mixed    mesophytic    composition. 


Introduction 

Plant  ecologists  have  been  interested  in  the  forests  of  southeastern 
Indiana  for  a  number  of  years.  The  Versailles  State  Park  and  Laughery 
Creek  Valley  areas  of  Ripley  County  have  been  of  particular  interest 
because  the  diverse  topography  of  that  region  induces  striking  differ- 
ences in  forest  types  within  very  short  distances.  According  to  Potzger 
(9),  the  well-drained  uplands  and  moderate  slopes  support  a  climax  of 
mixed  mesophytic  forest  dominated  by  beech  (Fagus  grandifolia)  and 
sugar  maple  {Acer  saccharwn) ,  and  which  includes  twenty  or  more  addi- 
tional species  of  lesser  importance.  Beech  is  also  an  important  member 
of  the  forests  on  the  poorly-drained  flat  uplands,  but  sugar  maple  is 
replaced  as  a  co-dominant  on  these  wet  sites  by  red  maple  {Acer  rubrum) 
and  sweet  gum  (Liquidambar  styraciflua) .  On  the  excessively-drained 
slopes  beech  is  absent;  however,  sugar  maple  continues  as  a  dominant 
species,  along  with  mesophytic  oaks,  ash  and  hickories  (9).

Ecology  211 

The  faculty  and  students  of  the  Conservation  Education  Summer 
Camp,  held  at  Versailles  State  Park  for  several  years,  focused  their  at- 
tention on  this  wide  range  of  habitats  and  forest  composition  in  the  vicin- 
ity of  the  Laughery  Creek  Valley.  Potzger  (9)  and  Stearns  (15)  studied 
the  ecological  relationships  of  the  forest  communities  within  the  State 
Park  area.  In  addition,  Potzger  and  Potzger  (13)  and  Potzger  and  Lim- 
ing (12)  worked  out  secondary  succession  patterns  on  the  flat  uplands 
of  Ripley  County.  The  distribution  patterns  and  associated  species  of 
beech  were  examined  by  Potzger  and  Chandler  (10)  in  ten  stands  in 
the  general  Laughery  Valley  area.  In  a  later  study,  Potzger  and  Chan- 
dler (11)  described  four  oak-dominated  forests  of  the  same  region. 

The  aims  of  this  study  were:  1)  to  intensively  study  one  of  the  best 
remaining  old-growth  upland  and  adjacent  slope  forests  of  the  area  that 
somehow  had  escaped  earlier  study;  2)  to  compare  the  above  stand  to 
a  frequently  studied  old-growth  stand  located  in  the  southeast  part  of 
the  Park;  and  3)  to  supplement  the  current  search  for  and  description  of 
areas  in  Indiana  that  are  suitable  for  preservation  under  the  Natural 
Areas  Act. 

Location  and  Description  of  the  Stands 

Versailles  State  Park  lies  in  the  Illinoian  Till  Plain  section  of  Indiana. 
Upland  areas  are  flat  to  gently  rolling,  but  Laughery  Creek  and  its 
tributaries  have  cut  deep  valleys  and  ravines  into  the  upland  plateaus. 
There  is  about  300  ft.  of  relief  in  the  immediate  area  with  Laughery 
Creek  dropping  to  about  700  ft  above  mean  sea  level  and  the  highest  flat 
uplands  reaching  slightly  above  1,000  ft  elevation.  Laughery  Creek  cut 
a  deep,  broad  steep-walled  valley  into  the  underlying  Ordovician  lime- 
stone as  it  carried  Pleistocene  meltwater.  The  region  is  very  scenic  with 
broad  panoramas. 

Laughery  Creek  is  the  approximate  dividing  line  between  the  Dear- 
born Upland  Physiographic  Provine  characterized  by  Ordovician  Age 
limestone  and  the  Muscatatuck  Regional  Slope  underlain  by  younger 
Silurian  Limestone.  One  of  the  study  sites  is  situated  in  each  physio- 
graphic province.  Both  stands  occupy  well-drained  Cincinnati  silt  loam 
soils.  The  study  areas  are  located  in  the  infrequently  visited  section  of 
the  Park  that  lies  south  of  U.  S.  Highway  50. 

The  first  stand,  referred  to  as  Jackson  Woods,  is  located  west  of 
Laughery  Creek  on  a  high  trapezoid-shaped  upland  promentory.  (The 
stand  names  used  in  this  paper  follow  the  nomenclature  used  by  Lindsey 
[6]).  It  is  situated  in  the  northwest  corner  of  section  18,  Twp.  7N,  Range 
12  E.  There  is  about  100  acres  of  forest  in  the  immediate  area,  but  the 
old-growth  upland  stand  covers  less  than  25  acres.  The  west,  north, 
northeast,  and  east-facing  slopes  of  the  upland  ridge  are  also  clothed  in 
good  mixed  forest.  The  upland  area  slopes  gently  toward  the  northeast, 
but  drainage  is  largely  internal  into  numerous  sinkholes  which  then 
feed  springs  and  seeps  along  the  valley  walls.  The  slopes  that  are 
watered  by  sub-surface  seeps  support  a  forest  that  is  strikingly  floodplain 
in  character,  although  it  occurs  on  a  75-80%  slope. 


212  Indiana  Academy  of  Science 

The  second  stand  is  referred  to  as  Potzger  Woods  in  honor  of  the 
late,  outstanding  plant  ecologist  from  Butler  University.  It  is  located 
on  a  gentle  northeast-facing  upland  slope,  which  is  drained  by  small 
ravines  in  the  upper  reaches  of  Turkey  Creek,  a  tributary  of  Laughery 
Creek.  The  stand  is  situated  east  of  Laughery  Creek  in  the  northeast 
quarter  of  Section  20,  Twp.  7  N,  Range  12  E.  The  least  disturbed  part  of 
the  stand  covers  less  than  10  acres. 

Both  areas  suffered  some  disturbance  as  a  consequence  of  private 
ownership  prior  to  park  acquisition.  Jackson  Woods  was  lightly  grazed 
by  cattle  for  a  number  of  years,  and  about  30  trees  were  cut  in  1936. 
For  about  seven  years  prior  to  1936,  a  few  beech  trees  were  cut  each 
year  for  firewood.  Little  information  exists  concerning  the  history  of 
Potzger  Woods,  but  apparently  only  limited  cutting  occurred  in  the 
1920's  and  30's.  The  presence  of  abundant  high  grade  walnut  in  both 
stands  indicates  that  neither  area  was  seriously  damaged  by  logging. 

Methods 

A  full  census  of  all  trees  greater  than  2.0  inches  dbh  (diameter 
breast  high)  was  taken  for  the  best  sections  of  each  stand.  A  total  of 
17.46  acres  was  tallied  in  Jackson  Woods  and  6.44  acres  in  Potzger 
Woods.  Stand  margins  were  excluded  from  the  full  tallies  to  avoid  com- 
munity transitions.  All  trees  over  4.0  inches  were  measured  to  the  near- 
est 0.1  inch  with  diameter  tapes,  and  trees  2.0  to  3.9  inches  were  counted 
and  recorded  by  species.  Smaller  trees,  tree  seedlings,  shrubs  and  herbs 
were  stratum  ranked  according  to  the  method  advanced  by  Lindsey, 
et  al.  (5)  to  establish  the  importance  of  each  species  within  each  stratum. 
Stratum  ranking  is  a  subjective  assignment  of  numerical  values  to  each 
species  according  to  its  contribution  to  the  density  and  cover  in  its  re- 
spective stratum.  Values  range  from  stratum  rank  9  (a  pure  stand  of 
a  single  species)  to  stratum  rank  1  (a  species  with  a  single  individual 
present). 

In  addition,  the  changes  in  forest  composition  on  contrasting  slope 
aspects  of  Jackson  Woods  were  examined  by  laying  a  continuous  one- 
half  mile  horizontal  belt  transect  along  the  contour  at  mid-slope.  Two 
600-ft  vertical  belt  transects  were  run  from  the  upland  to  the  flood- 
plain  to  determine  the  effect  of  topographic  position  on  forest  composi- 
tion. The  transects  were  divided  into  sections  43.56  ft  by  100  ft  so  that 
a  1/10  acre  sample  was  obtained  per  100-ft  horizontal  distance. 

Six  of  the  upland  sinkholes  in  Jackson  Woods  were  full  tallied  for 
trees  to  compare:  1)  small  sinks  (ca.  0.15  acre  each)  that  are  subject 
to  flooding  during  heavy  rains;  2)  small  sinks  (ca.  0.15  acre  each)  that 
apparently  seldom  or  never  contain  standing  water;  and  3)  large  sinks 
(ca.  0.4  acre  each)  that  apparently  do  not  flood.  The  occurrence  of 
ponding  in  small  sinks  was  established  by  examination  of  the  silt  coat- 
ings on  the  leaf  litter  and  by  the  absence  of  herbs,  shrubs  and  tree  re- 
production in  the  flooding  portion. 


Ecology  213 

The  soil  reaction  of  upland  and  slope  samples  was  determined  with 
a  Beckman  pH  meter;  soil  moisture  values  were  expressed  as  percentage 
oven  dry  weight.  Canopy  heights  were  measured  with  an  Abney  level. 

The  field  work  was  done  in  early  July  and  mid-September.  Full  tally 
plot  corners  were  marked  with  permanent  iron  rods  and  exact  locations 
are  available  from  the  authors. 

Stand  attributes  according  to  Lindsey  (4)  are  as  follows:  D2  = 
density  per  acre;  D3  =  relative  density;  B2  =  basal  area  per  acre;  B3  = 
relative  basal  area;  and  V3  =  importance  value  = 

D3  +  B3. 


Species  nomenclature  follows  Little   (7)   and  Fernald   (3)   for  trees  and 
other  species,  respectively. 

Results  and  Discussion 

Jackson  Woods 

Upland  Stand  Description.  The  primary  stand  attributes  of  the 
full-tally  section  of  this  stand  are  shown  in  Table  1.  Twenty-eight  species 
greater  than  4  inches  dbh  represent  a  stand  density  of  109.03  stems 
per  acre  and  a  stand  basal  area  of  111.67  square  ft  per  acre.  Although 
these  totals  are  slightly  less  impressive  than  those  for  the  best  old- 
growth  stands  in  the  state,  they  indicate  a  relatively  undisturbed  condi- 
tion. The  stand  is  of  mixed  composition,  but  heavily  dominated  by  beech 
and  sugar  maple,  which  total  57.5%  of  stand  importance  value. 
Beech  represents  nearly  a  third  of  stand  importance,  largely  because  of 
its  large  size  (over  half  of  the  stand  basal  area);  whereas,  sugar  maple 
attains  its  one-fourth  of  the  stand  importance  because  of  its  high  density 
(nearly  40%  of  the  stand  total),  particularly  in  the  small  size  classes. 

Examination  of  the  size-class  distribution  in  Table  2  gives  the  im- 
pression that  sugar  maple  is  rapidly  invading  the  stand,  in  large  measure 
at  the  expense  of  beech.  This  is  particularly  noteworthy  when  the 
ratios  of  the  number  of  stems  less  than  12  inches  dbh  to  the  number 
greater  than  12  inches  are  examined  for  the  two  species.  These  ratios 
are  1675/40  or  41.88  and  26/242  or  0.11  for  sugar  maple  and  beech, 
respectively,  when  stems  greater  than  2  inches  dbh  are  considered,  and 
699/40  or  17.48  and  8/242  or  0.03,  respectively,  for  stems  greater  than 
4  inches  dbh.  These  ratios  obviously  are  useful  only  for  determining 
possible  trends  in  stand  composition  since  many  beech-maple  dominated 
stands  exhibit  a  similar  preponderance  of  young  maples.  However,  beech 
usually  maintains  its  position  as  a  co-dominant  and  frequently  increases 
its  importance  value  as  the  stand  matures.  This  natural  process  of  selec- 
tion toward  beech  dominance  as  successional  maturity  is  reached  is 
frequently  enhanced  by  selective  logging  in  which  higher  grade  species 
such  as  oak,  walnut  and  tulip-poplar  are  removed,  leaving  the  lower 
quality  beech.  The  differential  rate  of  sugar  maple  reproduction  when 


214  Indiana  Academy  of  Science 

compared  to  beech  is  largely  offset  by  differential  survival  of  beech 
with  respect  to  sugar  maple.  Most  undisturbed  stands  seem  to  have 
much  greater  mortality  of  small  maples  than  of  small  beech.  Long-term 
detailed  studies  of  a  number  of  beech-maple  dominated  stands  should 
help  resolve  this  question.  Notwithstanding  these  comments,  the  ab- 
sence of  any  sugar  maple  stems  greater  than  24  inches  in  this  stand 
indicates  that  sugar  maple  will  undoubtedly  increase  in  the  larger  size 
classes  in  the  future,  assuming  the  continued  absence  of  disturbance. 
The  projected  increase  in  sugar  maple  may  be  partially  at  the  expense 
of  beech,  but  a  replacement  of  less  tolerant  species  such  as  tulip-poplar 
(Liriodendron  tulipif era) ,  walnut  (Juglans  nigra),  sassafras  (Sassafras 
albidum)   and  wild  cherry   (Primus  serotina)   is  more  probable. 

Tulip-poplar  is  the  sub-dominant  species  with  an  importance  value 
of  14.1%.  Moderate  selective  cutting  30  to  40  years  ago  has  apparently 
favored  this  relatively  intolerant  species.  Although  most  of  the  30  trees 
cut  in  1936  (just  prior  to  park  acquisition)  were  tulip-poplar,  the 
crown  openings  created  by  this  cutting  undoubtedly  favored  release, 
rapid  growth  and  regeneration  of  tulip-poplar,  serving  to  increase 
rather  than  decrease  tulip  importance.  Nearly  half  (96  of  204)  of  the 
tulip-poplar  stems  over  4  inches  dbh  fall  in  the  12  to  24  inch  size 
classes.  Expected  growth  increments  of  thrifty  tulip-poplars  in  canopy 
openings  would  be  on  the  order  of  one-fourth  to  one-half  inch  diameter 
increase  per  year  on  the  average.  This  growth  rate  would  date  the  estab- 
lishment of  many  of  the  middle-sized  tulip-poplars  as  canopy  trees  at 
about  30  to  40  years  ago. 

Other  species  worthy  of  comment  include  flowering  dogwood  (Cornus 
florida)  which  represents  6.5%  of  the  stand  (Table  1),  largely  by  virtue 
of  its  high  density  (13  stems  per  acre  larger  than  4  inches  dbh),  and 
walnut  at  4.6%  importance.  Walnut  is  very  well  represented  in  the  12 
to  24  inch  sizes  (49  of  66  total  stems),  indicating  that  it  was  also  favored 
by  the  canopy  openings  created  by  cutting.  Walnut  is  frequently  clumped 
in  the  larger  sinkholes  (see  Table  3)  of  the  area.  This  contagious  dis- 
persal is  favored  by  increased  light,  gravity  seed  dispersal  and  accumula- 
tion of  fertile  soil  in  the  sink  bottoms.  Elm,  wild  cherry  and  sassafras 
were  probably  favored  to  a  lesser  extent  by  the  earlier  cutting.  Six 
species  of  oak  and  hickory  represent  only  1.17%  of  the  stand  importance 
value.  The  absence  of  these  species  on  this  well-drained  site  is  a  matter 
of  conjecture,  since  there  is  no  record  of  recent  cutting  of  either  oak  or 
hickory.  Apparently,  even  the  moderately  tolerant  white  oak  is  unable 
to  successfully  compete  in  mature  upland  stands  in  this  area.  Canopy 
opening  would  not  have  favored  oak  and  hickory,  because  of  their  slower 
growth  rate  as  compared  to  tulip-poplar.  Large  chinquapin  oak 
(Quercus  muehlenbergii)  is  rather  common  along  the  drier  bluffs  and 
slopes,  where,  as  Reynolds  and  Potzger  (14)  pointed  out,  it  even  sur- 
passes white  oak  in  abundance.  On  the  uplands  it  is  an  inconsequential 
species,  however. 

Although  there  are  no  trees  greater  than  40  inches  dbh,  there  are 
128  stems  in  the  28-inch  or  greater  size  classes  for  an  average  of  nearly

8  large  trees  per  acre.  All  but  15  (88.3%)  of  these  large  trees  are 
beech  which  contributes  to  the  impression  that  this  stand  is  almost  en- 
tirely beech.  Potzger  and  Chandler  (10)  recorded  only  17  trees  greater 
than  30  inches  (based  on  a  total  sample  of  about  5  acres)  in  the  entire 
ten  stands  that  they  studied.  The  largest  individuals  of  noteworthy

and  ash  have  clear  boles  of  30  to  60  ft  with  very  little  taper.  The  general 
canopy  height  averages  about  115  to  120  ft  in  the  upland  stand,  with 
tulip-poplars  reaching  the  greatest  overall  height. 

The  tree  reproduction  data  are  summarized  in  Table  2,  so  stratum 
rank  values  are  not  listed  for  small  trees.  In  all,  27  species  contribute 
1,569  stems  in  the  2.0  to  4.0  inch  dbh  size  class. 

The  shrub  and  vine  stratum  is  dominated  by  hinder  a  Benzoin  (stra- 
tum rank  8),  particularly  in  the  larger  sinks  and  other  very  mesic 
situations.  Asimina  triloba  is  stratum  rank  5;  Rhus  radicans  and  Smilax 
rotundifolia,  4;  Parthenocissus  quinquefolia  and  Rites  cynosbati,  3; 
Sambucus  canadensis  and  Viburnum  acerifolium  are  minor  shrubs. 

Twenty-two  species  of  summer  herbs  were  stratum-ranked  as  follows : 
Galium  concinnum  and  Podophyllum  peltatum,  7;  Arisacma  triphyllum 
and  Galium  circaezans,  5;  Actaea  alba,  Boehmeria  cylindrica,  Circaea 
latifolia,  Viola  sp.,  4;  Impatiens  pallida,  Polygonatum  pubescens,  and 
Sanguinaria  canadensis,  3;  Cimicifuga  racemosa,  Dryopteris  hexagonop- 
tera,  Hydrastis  canadensis,  Jeffersonia  diphylla,  Menispermum  canadense, 
Panax  quinquef  olius ,  Phytolacca  americana,  Trillium  gleasoni,  2; 
Osmorhiza  claytoni  and  Hydrophyllum  appendiculatum,  1.  The  only 
herbs  present  with  marked  affinities  to  southern  forests  are  Cimicifuga 
and  Jeffersonia.  The  fern  flora  is  very  depauperate  for  a  rich,  mesic 
woods. 

Sinkhole  Comparison.  The  upland  stand  has  Karst  topography  that 
typically  develops  as  a  result  of  surface  collapse  into  solution  chambers 
in  the  underlying  limestone.  There  are  about  two  dozen  sinks  of  various 
sizes  in  the  17% -acre  stand.  Most  range  from  8  to  15  feet  deep,  and  vary 
in  bottom  configuration  and  subsurface  drainage.  They  may  be  grouped 
into  three  broad  categories  as  defined  in  the  Methods  Section.  Some  of 
the  larger  sinks  have  almost  impenetrable  tangles  of  grapevine,  Virginia 
creeper  and  spice  bush  thoroughly  interlaced  with  a  rank  growth  of 
jewel  weed  that  commonly  grows  shoulder  high. 

The  total  area  tallied  in  the  six  sinks  was  lVz  acres  or  about  8%  of 
the  entire  stand.  The  importance  values  for  species  present  in  the  three 
types  of  sinks  are  summarized  in  Table  3.  The  six  species  present  in 
the  small  sinks  subject  to  ponding  were  confined  to  the  rims  above  the 
level  of  flooding,  except  for  an  occasional  large  beech  in  the  bottom.  It 
is  of  interest  that  tulip-poplar,  walnut  and  slippery  elm  (Ulmus  rubra) 
are  absent  from  the  small,  ponding  sinks,  although  they  represent  nearly 
V±  of  the  importance  value  of  the  total  stand  (Table  1).  The  periodic 
ponding  may  prevent  seed  germination  near  the  sink  bottoms,  particularly 
the  largely  gravity  dispersed  walnut.  Collective  importance  values  for 
beech  and  sugar  maple  are  reduced  along  the  sinkhole  gradient  from 
79.0%  to  68.8%  to  58.5%  (Table  3),  although  they  are  clearly  the  domi- 
nant species  in  all  three  cases.  This  decrease  is  compensated  for  by  an 
increase  in  walnut,  slippery  elm,  American  elm  {Uhnus  americana)  and 
tulip-poplar.  The  fertile  soil  and  mesic  conditions  of  the  large  sink 
bottoms    provide    a    situation    similar    to    high    floodplains,    where    these 


Ecology  219 

species  typically  reach  their  best  development.  Tree  reproduction,  shrub 
and  herb  strata  are  well  represented  in  all  of  the  non-ponding  sinks, 
but  are  almost  totally  excluded  from  the  ponded  sections.  Consideration 
of  sinkhole  microenvironments  is  important  because  they  add  variety 
to  an  otherwise  uniform  area,  and  correspondingly  enrich  the  plant 
communities  present.

Slope  Forests.  The  west,  northwest  and  northeast-facing  slope 
aspects  represent  600  feet  or  0.6  acre  each  of  the  2,600-foot  belt  transect, 
and  the  north  and  east-facing  slope  aspects  represent  400  feet  or  0.4 
acre  each.  No  south  slope  was  present  in  that  immediate  area.  Data  for 
basal  area  per  acre  and  importance  values  are  summarized  in  Table  4. 
The  slope  both  lengthens  (vertically)  and  steepens  from  the  west  side 
around  to  the  east.  The  richness  of  the  woody  flora  decreases  and  soil 
moisture  increases  from  west  to  east.  The  soil  pH  remains  moderately 
acid  until  the  steeper  northeast  and  east-facing  slopes  with  numerous 
limestone  outcroppings  are  encountered,  then  it  becomes  slightly  basic. 
On  the  latter  slopes,  there  are  abundant  mid-slope  seepage  outlets  from 
the  internally-drained  upland  sinks.  Since  soil  moisture  readings  were 
taken  in  July  following  a  long  dry  period,  none  of  the  areas  had  high 
moisture  values. 

Species  shifts  follow,  in  general,  the  drouth  susceptibility  of  the 
slopes  (Table  4).  Trees  more  typical  of  more  xeric  slopes,  such  as  black 
locust  {Robinia  pseudoacacia)  (probably  an  escape),  Eastern  red  cedar 
(Juniperus  virginiana),  blue  beech  (Carpinus  caroliniana) ,  redbud 
{Cercis  canadensis)  and  dogwood  are  restricted  to  the  west  and  north- 
west-facing slopes.  Oaks,  hickories  and  beech  are  absent  from  the  mesic 
northeast  and  east-facing  slopes,  except  for  one  bitternut  hickory  (Carya

cordif  ormis) .  Both  basswood  (Tilia  americana)  and  walnut  increase  pro- 
gressively from  drier  to  mesic  slopes.  Sugar  maple  is  well  represented 
on  all  slopes  although  fluctuating  widely  in  both  basal  area  per  acre  and 
importance  value.  Also  of  interest  is  the  addition  of  species  more  typical 
of  floodplains  (American  elm,  hackberry  (Celtis  occidentalis) ,  green 
ash  (Fraxinus  pennsylvanica)  and  box-elder)  as  the  mesic  slopes  with 
subsurface  seeps  were  reached.  Kentucky  coffeetree,  sycamore  (Platanus 
occidentalis)  and  honey  locust  (Gleditsia  triacanthos)  were  present  on 
the  east  slope,  although  they  did  not  fall  within  the  transect. 

The  species-substrate  relationships  described  above  serve  to  illus- 
trate quantitatively  how  community  types  of  the  Laughery  Valley  change 
progressively  with  the  compass  in  this  diverse  topography.  The  richest 
flora  occurs  on  the  west  slope  community,  which,  according  to  Braun  (1), 
is  more  typically  mixed  mesophytic  than  is  either  the  upland  or  the  moist 
east  and  northeast-facing  slopes.  The  latter  are  undoubtedly  late  serai 
stages,  rather  than  mature  stands,  held  there  in  this  case  by  physio- 
graphic instability  and  excess  subsurface  moisture. 

The  results  from  two  vertical  belt  transects  down  the  east  slope 
from  the  upland  to  the  beginning  of  the  Laughery  floodplain  are  com- 
bined and  summarized  in  Table  5.  The  linear  100-foot  increments  repre- 
sent horizontal  distances  since  slope  corrections  were  made.  The  combined 
transect  represents  0.2  acre  per  100  feet  increment.  Sections  1  and  2 
are  on  the  relatively  level  upland;  section  3  represents  the  abrupt  break 
at  the  bluff;  sections  4  and  5  the  steep  (75-80°)  mid-portion  of  the  slope, 
and  section  6  the  less  steep  beginning  of  the  floodplain.  (Slope  percent- 
ages are  given  for  only  sections  4  and  5  because  the  slope  percentages 
change   continually  in  the   other  sections.) 

The  stand  attributes  of  the  upland  sections  were  not  appreciably 
different  from  those  of  the  upland  stand  in  general  (Table  1),  except 
that  the  relatively  small  transect  sample  missed  many  of  the  rarer 
species  of  the  upland  stand.  Sugar  maple  was  represented  in  all  slope 
sections,  although  the  basal  area  and  importance  values  fluctuated  rather 
widely.  Beech  stopped  at  the  bluff;  whereas,  oak,  hickory  and  blue  ash 
were  restricted  to  the  bluff  edge  and  dropped  out  as  the  mesic  lower 
slopes  were  reached.  The  vertical  distribution  of  these  species  is  similar 
to  the  horizontal  distribution  shown  in  Table  4,  with  respect  to  moisture 
conditions.  Basswood,  walnut  and  slippery  elm  increased  in  response  to 
increasing  mesic  conditions  as  they  did  in  the  slope  aspect  comparison. 
Species  typical  of  wet  sites,  such  as  box-elder,  sycamore  and  honey-locust 
were  encountered  as  the  floodplain  was  neared. 

Potzger  Woods 

Stand  Description.  Species  attributes  are  listed  in  Table  6  for  the 
24  species  greater  than  4  inches  dbh.  Both  the  stand  density  of  121.43 
stems  per  acre  and  the  stand  basal  area  of  116.58  square  feet  per  acre  are 
slightly  higher  than  the  corresponding  values  for  the  preceding  stand. 
This  stand  is  heavily  dominated  by  sugar  maple  and  beech  with  the  two 
species  accounting  for  nearly  70%  of  stand  importance.   Also  of  interest

is  the  5.05%  importance  value  for  walnut,  which  represents  one  of  the 
highest  upland  stand  values  for  that  species  in  the  state. 

When  the  size-class  data  are  examined  (Table  7)  the  preponderance 
of  small  sugar  maple  is  immediately  apparent.  Again,  ratios  were  calcu- 
lated for  the  proportion  of  sugar  maple  and  beech  below  and  above  12 
inches.  For  sugar  maple  greater  than  2  inches  the  ratio  of  small  to 
large  trees  is  1002/26  or  38.54,  and  the  corresponding  figure  for  greater 
than  4  inches  is  416/26  or  16.00.  The  ratios  for  beech  are  10/84  or  0.12 
and  8/84  or  0.10,  respectively.  A  comparison  with  previous  studies  of 
Potzger  Woods  indicates  that  sugar  maple  is  gaining  in  stand  impor- 
tance, possibly  at  the  expense  of  beech.  This  is  discussed  in  more  detail 
in  the  section  comparing  the  two  stands. 

There  are  52  stems  greater  than  28  inches,  or  an  average  of  8  large 
trees  per  acre.  Forty-four  (84.4%)  of  the  large  trees  are  beech.  The 
largest  individuals  of  species  in  the  full  tally  plot  include:  beech  45.8, 
tulip-poplar  35.2,  sugar  maple  32.4,  sassafras  29.0   (44  feet  clear  bole),

black  gum  28.7,  hackberry  28.1,  basswood  25.4  and  walnut  24.5.  The 
general  canopy  height  of  this  stand  is  110  to  115  feet  with  a  few  taller 
trees  reaching  120  feet.  Increment  cores  taken  from  the  outer  portion 
of  large  tulip-poplar  and  beech  trees  (34.8  and  34.1  inches  dbh,  respec- 
tively) indicate  that  they  are  still  steadily  growing:  a  3-inch  increase  in 
radius  in  24  years  or  0.25  inch  diameter  average  increase  per  year  for 
tulip-poplar,  and  a  3-inch  radial  increase  in  33  years  or  0.18  inch 
average  diameter  increase  per  year  for  beech.  A  complete  coring  of  a 
22.5-inch  walnut  showed  the  tree  to  be  66  years  old,  or  an  average 
annual  diameter  growth  increase  of  slightly  over  Vz  inch. 

Stratum  rank  values  for  10  species  of  shrubs  and  vines  are:  hinder  a 
benzoin  and  Smilax  rotundi folia,  5;  Viburnum  aceri folium  and  Vitis  sp., 
4;  Parthenocissus  quinquefolia  and  Ribes  cynosbati,  3;  Asimina  triloba, 
Rhus  radicans,  Viburnum  rufidulum  and  Sambucus  canadensis,  2. 

Twenty-four  species  of  summer  herbs  and  ferns  had  the  following 
stratum  rank  values:  Impatiens  pallida,  7;  Galium  concinnum  and 
Urtica  procera,  6;  Galium  circaezans  and  Podophyllum  peltatum,  5; 
Adiantum  pedatum,  Arisaema  triphyllum,  Athyrium  asplenioides,  Circaea 
latifolia,  Osmorhiza  claytoni,  and  Polygonatum  pubescens,  4;  Cimicifuga 
racemosa,  Dryopteris  hexagonoptera,  Menispermum  canadense,  Ranunculus 
septentrionalis,  Smilacina  racemosa,  Solidago  caesia  and  Viola  sp.,  3; 
Actaea  alba,  Anemone  quinquefolia  Boehmeria  cylindrica,  Polystichum 
acrostichoides  and  Sanguinaria  canadensis,  2;  and  Panax  quinquef olius , 
1.   The  fern  flora  is  much  richer  than  in  Jackson  Woods. 

Comparison  with  Previous  Studies.  Potzger  Woods  is  one  of  the 
few  stands  in  the  state  to  have  four  forest  ecological  studies  during  a 
20-year  period.  Unfortunately,  the  exact  plot  and  sample  point  locations 
were  not  permanently  marked  so  that  exact  comparisons  could  be  made. 
Potzger  (9)  plot  sampled  the  woods  using  33  ten-meter  square  quadrats, 
for  a  sample  totalling  about  12.5%  of  the  nearly  6V2  acres  full  tallied  in 
this  study.  In  1955,  Petty  (8)  full-tallied  5  acres  of  the  least-disturbed 
part  of  the  stand;  however,  it  is  unknown  if  the  present  full-tally  com- 
pletely included  the  earlier  5-acre  census.  Stearns  (15)  intensively 
sampled  the  area  by  the  random  pairs  method  by  establishing  140  points 
and  recording  data  for  280  trees  over  4  inches  dbh.  His  sample  would 
be  equivalent  to  nearly  36%  of  the  782  trees  included  in  this  tally. 

A  comparison  of  these  studies  clearly  indicates  the  value  of  taking 
full  tallies  of  forest  remnants  whenever  possible.  Although  there  have 
undoubtedly  been  some  compositional  changes  in  the  stand  during  the 
past  18  years,  many  of  the  differences  in  stand  attributes  obtained  in  the 
four  studies  are  due  to  differences  in  sampling  adequacy  and  data 
interpretation. 

This  is  particularly  apparent  when  the  rarer  species  are  considered. 
In  both  full  tallies,  24  species  were  recorded,  although  only  21  were  com. 
mon  to  the  two  studies.  Differences  in  the  species  lists  result  largely 
from  the  plots  not  being  exactly  the  same  size  and  in  the  same  location, 
since    only   one   individual  was   involved   for  five   of   the    six   species   in 


226  Indiana  Academy  of  Science 

question.  The  other  case  is  a  question  of  how  consistently  white  ash 
(Fraxinus  americana)  and  green  ash  (F.  peyinsylvanica)  can  be  separated 
in  the  field.  There  should,  obviously,  be  no  problem  in  obtaining  com- 
parable species  lists  for  a  stand  when  full  tallies  include  the  identical 
stand  segment.  By  comparison,  Potzger  (9)  recorded  only  16  of  the  24 
species  listed  in  this  study  with  his  12.5%  sample  and  Stearns  (15) 
encountered  only  15  species  in  a  36%  sample,  the  latter  being  a  much 
more  intensive  forest  sample  than  is  usually  taken.  Coefficients  of  com- 
munity, based  on  relative  density,  were  calculated  for  the  four  studies  of 
the  single  stand.  Relative  density  is  used  in  this  comparison  since  impor- 
tance values  were  not  determined  in  the  two  earlier  studies.  The  coeffi- 
cients of  community  ranged  from  61.8  to  82.3%  similarity  with  the  two 
full  tallies  giving  the  greatest  similarity.  The  similarity  between  the  two 
full  tallies  probably  would  have  been  even  closer  except  that  density  for 
the  former  study  was  based  on  3-inch  and  larger  trees;  whereas,  this 
study  was  based  on  trees  greater  than  4  inches  dbh. 

Substantial  composition  changes  could  also  occur  in  an  18-year 
period.  The  main  changes  in  density  during  the  13-year  period  between 
Petty 's  (8)  study  and  this  study  include  an  increase  in  sugar  maple 
from  42.4%  to  56.5%  and  a  decrease  in  American  elm  from  5.0%  to 
1.3%.  All  other  species  have  remarkably  constant  values  between  the 
two  studies.  The  latter  change  is  largely  due  to  mortality  of  American 
elm  due  to  disease.  Sugar  maple  most  likely  is  increasing  substantially 
in  density,  particularly  in  the  smaller  size  classes  (Table  7).  When 
the  present  sugar  maple  density  values  are  compared  to  Potzger's  1950 
study,  the  change  is  even  greater:    39.9%  to  56.5%. 

Stearns  (15)  found  beech  and  sugar  maple  importance  values  of 
43.8%  and  24.5%,  respectively,  as  compared  to  30.7%  and  38.5%,  respec- 
tively, in  this  study.  Comparable  shifts  in  relative  density  and  relative 
basal  area  are  as  follows:  sugar  maple  increased  from  33.9%  to  56.5% 
density,  and  from  15.0%  to  20.5%  for  basal  area;  whereas,  beech 
decreased  from  27.5%  to  11.8%  density  and  from  60.1%  to  49.6%  basal 
area.  Some  differences  would  occur  due  to  sampling  differences,  as  men- 
tioned previously,  but  these  data  indicate  a  definite  trend  toward  increased 
maple  importance  largely  at  the  expense  of  beech. 

This  comparison  is  not  intended  to  be  a  criticism  of  any  previous 
study.  Each  study  was  well  conceived  and  properly  executed.  The  prob- 
lem is  one  of  sampling  intensity  and  adequacy,  particularly  with  respect 
to  low  frequency  species.  Since  full  tallies  can  be  made  for  most 
accessible  stands  at  the  rate  of  about  one  acre  per  hour  for  all  field  labor, 
it  is  hardly  justifiable  when  working  with  small  stands,  to  compromise 
the  adequate  stand  data  obtained  from  full  tallies  for  the  slight  gain 
in  field  efficiency  obtained  by  low  intensity  sampling.  Furthermore,  it  is 
questionable  whether  Potzger  Woods  could  have  been  sampled  by  taking 
140  sets  of  random  pairs  of  trees  in  less  time  than  the  six  hours  re- 
quired in  this  study  to  full  tally  the  stand. 


Ecology  227 

Comparison  of  Stands 

There  is  remarkable  vegetational  and  floristic  similarity  between  the 
two  stands  (Tables  1  and  6).  Twenty-one  of  the  24  species  of  woody 
plants  greater  than  4  inches  dbh  occurring  in  Potzger  Woods  are  also 
found  in  Jackson  Woods.  Beech  has  almost  identical  absolute  values  for 
density  and  basal  area  in  the  two  stands,  but  sugar  maple  represents  over 
13%  greater  importance  in  Potzger  Woods  by  virtue  of  a  very  high 
density  per  acre  of  68.6  and  nearly  double  (23.9  to  12.7)  its  former  basal 
area  value.  The  only  other  substantial  shifts  are  decreases  in  importance 
value  for  tulip-poplar  from  14.1%  to  2.8%  and  dogwood  from  6.5% 
to  1.5%.  The  combined  importance  value  for  beech  and  sugar  maple  is 
11.7%  greater  in  Potzger  Woods  than  in  Jackson  Woods,  compensating,  in 
part,  for  the  decreased  importance  of  tulip-poplar  in  the  former  stand. 

When  the  two  stands  were  compared  by  coefficients  of  community 
based  on  tree  importance  values,  the  stands  were  77.8%  similar.  This 
compares  well  with  the  highest  coefficient  found  (82.3%)  when  the  four 
studies  of  Potzger  Woods  were  compared. 

The  two  stands  are  also  very  similar  with  respect  to  shrub  and 
herb  composition.  All  nine  of  the  shrub  and  vine  species  present  in 
Jackson  Woods  were  present  in  Potzger  Woods.  The  only  additional 
shrub  in  Potzger  Woods  was  Viburnum  ruficluhim,  the  southern  black 
haw.  Coefficients  of  community  based  on  stratum  rank  values  for  shrubs 
and  vines  yielded  a  similarity  percentage  of  80.0.  Sixteen  of  the  22  and 
24  herb  species  found  in  Jackson  and  Potzger  Woods,  respectively,  were 
in  common  to  both  woods.  The  coefficient  of  community  based  on  herb 
species   was   61.5%    similarity. 

With  such  close  similarity  between  the  local  climates,  physiography, 
drainage  and  soils  of  the  two  sites,  lack  of  vegetation  similarity  would  be 
anomalous.  However,  the  degree  of  similarity  described  here  is  much 
closer  than  for  most  individual  stands  within  a  forest  association. 

Apparently  even  the  time  and  amount  of  past  disturbance  has  been 
similar.  When  the  density  was  plotted  (on  the  ordinate)  per  size  class 
(on  the  abscissa)  on  semi-log  paper,  each  of  these  stands  exhibited  the 
same  departure  from  the  straight  line  relationship  considered  typical  of 
old-growth  stands.  Both  stands  have  similar  pronounced  plateaus  in  the 
18-  to  30-inch  size  classes,  which  indicate  substantial  disturbance  during 
the  same  time  period.  The  disturbance  largely  reflects  the  moderate 
cutting  about  30  to  40  years  ago,  as  previously  mentioned.  This  selective 
cutting  favored  seedling  establishment  and  release  of  established  indi- 
viduals of  relatively  intolerant  species  such  as  tulip-poplar,  walnut,  ash, 
slippery  elm,  wild  cherry  and  sassafras.  These  relationships  become  clear 
when  Tables  2  and  7  are  examined. 

Phytogeographic  Position  of  the  Stands 

In  her  discussion  of  the  Area  of  Illinoian  Glaciation  in  southeastern 
Indiana  and  adjacent  southwestern  Ohio,  Braun  (1)  states:  "In  transi- 
tional bands  between  the  flats  and  the  slopes  of  the  area,  where  drainage 


228  Indiana  Academy  of  Science 

and  aeration  are  better  and  yet  dissection  is  not  apparent,  sugar  maple 
appears  with  the  beech.  This  beech-maple  forest  is  a  serai  community 
which  is  replaced  by  mixed  mesophytic  forest  whenever  dissection 
becomes  more  evident."  She  goes  on  to  add  concerning  the  dissected 
areas  of  that  region:  "In  most  of  the  mixed  mesophytic  forest  communi- 
ties of  this  section  of  the  Western  Mesophytic  Forest  region,  beech 
forms  approximately  50  per  cent  of  the  canopy.  In  the  mixed  mesophytic 
communities,  tulip  tree,  sugar  maple,  basswood,  walnut  and  white  ash 
are  almost  always  present  together  with  some  six  or  eight  species  of 
lesser  frequency." 

The  authors  feel  that  the  upland  stands  described  in  this  paper  fit 
Braun's  description  almost  exactly.  Both  sites  are  well-drained,  but  not 
excessively  dissected.  Although  the  importance  values  (Tables  1  and  6) 
give  the  impression  that  maple  is  co-dominant  with  beech,  inspection  of 
the  basal  area  columns  (the  best  single  attribute  for  expressing  domi- 
nance) places  sugar  maple  in  more  nearly  its  actual  position.  In  both  of 
these  stands,  beech  represents  about  50%  of  the  stand  basal  area,  while 
10  and  8  additional  species  (including  all  of  those  Braun  mentioned)  have 
about  1%  or  greater  relative  basal  area  in  Jackson  and  Potzger  Woods, 
respectively.  Presently,  these  upland  stands  should  be  classified  as 
beech  and  sugar  maple  dominated  mixed  mesophytic  forests. 

As  previously  mentioned,  many  old-growth  stands  have  prodigious 
sugar  maple  reproduction  and  very  few  young  beech,  but  differential 
survival  rates  compensate  to  keep  beech  persisting  or  even  increasing  as 
a  co-dominant.  This  will  no  doubt  be  the  short-term  effect  as  the  stands 
continue  to  recover  during  the  next  50  years  or  so  from  the  moderate 
past  disturbance.  It  would  appear,  however,  that  over  long  periods  beech 
may  lose  importance  as  the  physiography  and  stands  mature.  Should  this 
occur,  the  stands  would  be  expected  to  become  more  mixed  in  total  com- 
position with  sugar  maple  gaining  somewhat  in  importance  value.  The 
latter  situation  is  exemplified  in  the  west-facing  slope  data  in  Table  4. 
Excluding  black  locust  (one  individual)  and  Eastern  red  cedar  (which 
was  confined  to  one  small  limestone  outcrop),  14  species  each  represent 
greater  than  1%  of  the  west-facing  slope  importance  value,  indeed  a 
very  mixed  stand  with  no  species  clearly  dominant.  The  west-facing  slope 
represents  mature  but  not  over-dissected  topography  and  a  slightly  drier 
than  average  aspect.  It  is  expected  that  the  upland  stand  composition 
will  approach  that  currently  occurring  on  the  west-facing  slope,  as  the 
physiography  of  the  upland  matures. 

Although  these  mixed  forests  are  not  the  true  Mixed  Mesophytic 
forests  typical  of  the  Cumberland  Mountains,  they  were  derived  from 
that  type  in  response  to  Post-Pleistocene  northward  migration  and  the 
attendant  compositional  changes  as  the  forest  segregated  in  the  complex 
of  habitats  in  the  Laughery  Valley  (1).  Neither  yellow  buckeye  nor 
white  basswood,  considered  by  Braun  (1)  as  indicators  of  the  Mixed 
Mesophytic  type,  were  found  in  the  vicinity  of  the  study  area.  Both  are 
reported  in  Clifty  Falls  State  Park,  located  about  25  miles  south,  and 
Deam  (2)  reports  white  basswood  for  Ripley  County,  but  a  persistent 
search  in  these  stands  failed  to  produce  either  species. 


Ecology  229 

Future  work  on  the  forests  of  the  Laughery  Valley  should  center  on 
long-term  changes  within  the  best  described  old-growth  stands  and  relat- 
ing these  stands  to  the  forest  complex  of  the  region  as  a  whole. 


Summary 

1.  Two  old-growth  upland  forests  were  studied  by  taking  full  tallies  of 
all  trees  over  2.0  inches  dbh  for  segments  of  17.46  acres  and  6.44  acres, 
respectively,  in  Jackson  and  Potzger  Woods. 

2.  Both  stands  are  beech  and  sugar  maple-dominated  mixed  mesophytic 
forests  with  the  two  dominant  species  totaling  57.5%  and  69.2%  of 
the  importance  value,  respectively.  Ten  and  eight  other  species  each 
represent  about  1%  or  greater  importance  values  in  the  two  stands, 
respectively. 

3.  Sugar  maple  dominates  the  smaller  size  classes,  indicating  that  it  is 
likely  increasing  in  stand  importance,  probably  in  response  to  limited 
disturbance  about  30  to  40  years  ago. 

4.  Intolerant  species  such  as  tulip-poplar,  walnut,  elm  and  wild  cherry 
have  been  favored  by  past  cutting  which  created  rather  extensive 
canopy  openings. 

5.  The  forest  composition  of  sinkholes  changes  in  response  to  ponding  or 
improved  internal  drainage.  Beech  and  sugar  maple  decrease  in 
importance,  but  walnut,  elm  and  tulip-poplar  increase  with  increases 
in  internal  drainage  and  increases  in  sinkhole  size. 

6.  The  effect  of  slope  aspect  on  forest  composition  was  determined  by 
transect  sampling.  The  west-facing  slope  is  a  mixed-mesophytic 
forest  with  many  species  sharing  dominance.  Oak  and  hickory  species 
increase  in  importance  value  on  the  excessively-drained  northwest 
and  north-facing  slopes.  The  steep  northeast  and  east-facing  slopes 
are  very  moist  due  to  subsurface  seeps;  this  results  in  a  species  com- 
position similar  to  floodplains.  Sugar  maple  occurs  on  all  slopes,  but 
beech  is  absent  from  the  northeast  and  east  slopes. 

7.  A  comparison  of  four  studies  of  Potzger  Woods  based  on  different 
sampling  methods  indicates  that  rarer  species  were  encountered  only 
in  full  tallies.  Since  1956,  sugar  maple  has  increased  in  stand  im- 
portance, possibly  at  the  expense  of  beech,  which  has  decreased. 

8.  Changes  in  stand  composition  over  the  next  several  decades  will  likely 
show  additional  recovery  from  disturbance  and  a  gain  in  sugar  im- 
portance at  the  expense  of  the  more  intolerant  species.  Beech  will 
likely  hold  its  position  as  the  stand  co-dominant. 

9.  As  the  physiography  matures  and  becomes  more  dissected  over  a 
great  number  of  years,  the  stand  should  become  more  mixed  meso- 
phytic in  composition  rather  than  the  present  beech  and  maple 
dominated   mixed   composition.

A  Study  of  Collembolan  Populations  Associated  with  Four 
Serai  Stages  Leading  to  the  Beech-Maple  Climax 

Patricia  M.  Arnett,  Indiana  State  University 


Abstract 

Ninety-six  litter  samples  of  one  square  decimeter  each  were  taken  in 
April  through  July  from  an  old  field,  oak  and  maple-oak  dominated  serai 
stages,  and  a  beech-maple  climax  in  Parke  County,  Indiana.  The  objective 
was  to  determine  the  relationship  between  Collembola  and  the  serai  stages. 

From  the  1821  Collembolans  collected  through  modified  Tullgren  fun- 
nels, 59  species  were  found.  The  maple-oak  had  more  species  than  any 
other  area.  This  difference  was  highly  significant.  The  oak  area  had  a 
higher  number  of  individuals  per  100  cm3  of  litter  than  the  other  areas. 
This  difference  was  highly  significant.  The  oak  area  had  the  most  indi- 
viduals, the  largest  volume  of  litter,  the  highest  total  of  prominence  values 
of  all  species,  and  the  greatest  weekly  average  of  individuals.  In  all  attri- 
butes the  field  had  the  lowest  value.  Isotobryoides  ochracius  Maynard  and 
Onychiurus  armatus  Tullberg  were  more  frequent  in  the  maple-oak  area 
than  in  the  other  areas.  The  difference  was  highly  significant.  A  three- 
dimensional  ordination  showed  the  similarity  between  the  Collembola  and 
the  tree  composition  increased  with  each  successive  serai  stage.  The 
ordination  indicated  the  collembolan  populations  of  the  wooded  areas  were 
more  closely  related  to  each  other  than  to  the  Collembola  in  the  field. 

Introduction 

Collembola  are  common  inhabitants  of  the  humus  and  upper  soil 
layers  in  many  ecological  situations.  The  principal  objective  of  this  study 
was  to  determine  the  relationship  of  collembolan  populations  to  plant 
serai  stages.  Leaf  litter  was  collected  from  an  old  field,  and  the  oak, 
maple-oak,  and  climax  beech-maple  areas  of  Allee  Memorial  Woods, 
which  is  located  one  and  one-half  miles  northwest  of  Annapolis,  Parke 
County,  Indiana.  The  Collembola  extricated  from  the  litter  were  counted 
and  identified. 

Description  of  study  area 

Allee  Woods  is  in  the  Tipton  Till  Plain  close  to  the  southern 
boundary  of  the  Wisconsin  glaciation  (8).  Soils  are  melanized  podzolics 
with  low  fertility  (7).  The  woods  are  severely  dissected  with  170  feet  of 
relief.  Three  deep  gorges  are  present  along  with  a  high  bluff  over  Sugar 
Creek  and  numerous  sloping  ravines.  All  study  sites  were  on  the  upland. 
Allee  Woods  was  chosen  for  study  because  of  the  presence  of  numerous 
serai  stages  and  a  remnant  of  beech-maple  dominated  climax  forest. 

The  beech-maple  area  represented  the  climax  vegetation  in  the 
woods.  There  has  been  no  cutting  although  windthrow  has  removed  a 
few  mature  Acer  saccharum  Marsh,  and  Fagus  grandifolia  Ehrh.  Beech 
and  sugar  maple  are  co-dominants  with  Liriodendron  tulipifera  L.  an 
important  associate.  The  understory  consists  primarily  of  sugar  maple 
and  beech  saplings  and  Cornus  florida  L.    The  soil  is  silt  loam  and  is 

231 


232  Indiana  Academy  of  Science 

slightly    acid.     The    litter    depth    averaged    3.83    centimeters.     A    slight 
southwestern  slope  was  present. 

The  maple-oak  probably  represented  an  intermediate  stage  between 
the  beech-maple  climax  and  the  oak  stage  as  evidenced  by  the  large 
number  of  sugar  maple  saplings.  It  was  selectively  cut  about  the  turn  of 
the  century  when  some  white  oaks  were  removed.  Quercus  alba  L., 
Quercus  rubra  L.,  and  sugar  maple  are  dominant  species.  The  under- 
story  is  mainly  beech,  sugar  maple,  and  dogwood.  The  soil  is  slightly 
acid  silt  loam.  The  average  litter  depth  is  4.41  centimeters.  The  letter  is 
more  uniformly  spread  over  the  ground  in  this  area  than  in  the  others. 
The  area  slopes  gently  toward  the  west. 

The  oak  area  is  predominantly  white  oak  and  red  oak.  Sugar  maple, 
Asimina  triloba  (L.)  Dunal.,  and  Ostrya  virginiana  (Mill)  K.  Koch  form 
the  understory.  The  soil  varies  from  acid  to  slightly  acid  loam.  This 
area  was  completely  cut  over  about  fifty  years  ago  and  has  remained 
undisturbed.  The  present  evenly  aged  trees  represent  reproduction  and 
sprouting  stumps.  This  area  had  the  highest  average  litter  depth,  4.58 
centimeters,  consisting  primarily  of  oak  leaves.  The  area  slopes  slightly 
toward  the  south. 

Tulip-poplar,  Acer  rubrum  L.,  and  Sassafras  albidum  (Nutt.)  Nees 
are  the  trees  most  abundant  in  the  old  field.  The  soil  is  silt  loam  and  is 
slightly  acid.  The  field  has  a  slightly  western  slope.  This  area  had  the 
least  average  amount  of  litter,  3.21  centimeters.  The  field  was  previously 
pastured  and  cultivated  but  has  been  abandoned  for  about  thirty  years. 
Several  successful  stages  are  present  with  parts  of  the  field  covered 
mainly  by  grasses  while  other  sections  have  low  shrubby  vegetation  or 
small  to  medium-sized  trees. 


Methods  and  Materials 

A  100-  by  200-foot  tract,  presumably  representative  of  the  vegeta- 
tion in  each  of  the  four  areas,  was  chosen.  Within  each  tract,  sample 
plots  one  decimeter  square  were  selected  at  random  before  the  actual 
sampling  began.  Each  week  for  the  12  weeks  from  April  20  to  July  5, 
1968,  two  samples  of  leaf  litter  from  each  tract  were  taken  by  means  of 
a  trowel.  The  depth  of  the  litter  was  measured  to  the  nearest 
centimeter. 

To  prevent  condensation  on  the  sides  of  the  funnel  and  the  consequent 
loss  of  organisms,  the  litter  was  inverted  and  gently  placed  in  a 
Tullgren  funnel  so  that  numerous  air  passages  existed  between  the 
litter  and  funnel  wall.  A  15-watt  bulb  was  suspended  3-4  inches  above 
the  sample  for  24  hours.  Insects  were  collected  in  95  per  cent  ethanol  to 
preserve  coloration.  The  nomenclature  followed  that  of  Maynard  (6).  A 
species  list  is  located  in  Table  1.  Voucher  specimens  are  on  file  in  the 
Indiana  State  University  entomological  research  collection.

Analysis  of  data 

The  ordination  procedure  (3,  1)  is  based  on  prominence  values  per 
species  per  community.  From  the  prominence  values,  which  are  equal 
to  the  density  times  the  square  root  of  the  frequency,  a  coefficient  of 
community  can  be  calculated.  The  inverse  of  the  coefficient  of  two 
stands  can  be  equated  with  linear  distance  and  transformed  into  a  three- 
axis  spatial  pattern  which  will  show  a  significant  correlation  between 
the  actual,  measured  distances  and  the  original  coefficient  of  community 
between  the  two  given  stands.  Collembola  were  ordinated  in  three  dimen- 
sions by  this  method.  The  trees  were  ordinated  in  a  slightly  different 
manner.  A  full  tally  of  all  trees  whose  diameter,  breast  height,  was 
greater  than  2  inches  was  made  for  each  area.  The  average  of  relative 
density  and  relative  basal  area  for  each  species  with  dbh  equal  to  4.0 
inches  or  more  is  called  the  importance  value  (5).  Importance  values 
were  used  instead  of  prominence  values  in  the  computations.  Chi- 
square  tests  were  used  to  test  conclusions  concerning  relative  density  and 
frequency  of  species  in  each  area. 

Results  and  discussion 

A  total  of  1821  individuals  of  Collembola  was  collected,  including  59 
species.  The  total  amount  of  litter  collected  was  38,500  cubic  centimeters. 
For  all  four  tracts  combined  there  was  an  average  of  4.72  individuals  per 
unit  volume.   A  unit  volume  is  defined  as  one-tenth  of  a  cubic  decimeter.

There  was  an  average  depth  of  4.02  centimeters  of  litter  per  sample.  The 
lowest  number  of  Collembola  ever  collected  from  a  sample  was  0.00  in 
one  old  field  plot.  The  highest  number  was  163  from  a  plot  in  the  oak 
area. 

The  oak  area  was  unique  in  many  ways  (Table  2).  It  had  (a)  the 
highest  average  number  of  individuals  (density)  per  unit  volume;  (b) 
the  greatest  number  of  individuals;  (c)  the  highest  average  litter  depth; 
(d)  the  highest  total  of  prominence  values  of  all  species;  and  (e)  the 
largest  average  number  of  individuals  per  week.  In  every  attribute  the 
old  field  had  the  lowest  value.  The  beech-maple  area  was  intermediate  in 
value  for  every  characteristic.  Only  once  did  the  maple-oak  area  have 
the  highest  value;  it  had  the  greatest  total  number  of  species  present 
per  area. 

The  number  of  individuals  per  unit  volume  was  greatest  in  the  oak 
area  followed  by  decreases  in  relative  abundance  in  the  beech-maple, 
maple-oak,  and  old  field  areas.  This  difference  was  highly  significant 
(X2  —  213.96,  3df).  The  maple-oak  area  had  more  species  present  in  the 
litter  (44)  than  the  other  areas.  The  difference  was  significant 
(X2  =  9.60,  3df).  A  possible  explanation  is  that  the  maple-oak  area  com- 
bines the  features  and  hence  Collembola  of  the  oak  and  beech-maple 
areas.  Although  the  old  field  had  an  average  depth  of  3.21  centimeters, 
some  of  this  depth  is  a  result  of  the  cushioning  and  buoyant  effect  of 
the  grasses  in  the  litter.    Hence  the  value  cited  is  probably  high. 

Isotobryoides  ochracius  Maynard  appeared  in  71  per  cent  of  all 
samples  in  the  maple-oak  area  but  in  only  eight  per  cent  of  the  samples  in 
the  old  field.  This  difference  was  highly  significant  (X2  =  15.32,  3df). 
Onychiurus  armatus  Tullberg  was  present  in  83  per  cent  of  the  maple- 
oak  samples  but  in  only  12  per  cent  of  the  old  field  samples.  The  differ- 
ence was  highly  significant  (X2  =  10.48,  3df).  Table  3  lists  the  density 
per  unit  volume  and  prominence  values  for  the  ten  most  common  species. 

Some  species  could  not  be  identified  because  of  the  absence  of 
suitable  taxonomic  keys.  More  samples  over  a  longer  period  of  time  might 
allow  us  to  identify  an  increased  number  of  the  more  difficult  species. 
Some  of  the  immature  stages  cannot  be  identified  beyond  family  (2). 
Sminthuridae  sp.  A,  which  has  occurred  three  times  but  only  in  the  old 
field,  may  be  an  indicator  species.  Similarly,  Sminthuridae  sp.  C  has 
occurred  only  in  the  beech-maple  area  and  could  be  an  indicator  species. 

The  most  important  species  in  terms  of  density,  frequency,  and 
prominence  value  is  Tomocerus  minor  Lubbock.  The  second  most  impor- 
tant is  Onychiurus  armatus.  The  former  was  cosmopolitan  in  distribu- 
tion while  the  latter  is  prevalent  in  the  maple-oak  area.  The  most 
important  genus  in  terms  of  density,  frequency,  and  prominence  value  is 
Entomobrya  followed  by  Tomocerus  and  Onychiurus.  The  most  impor- 
tant family  by  the  same  criteria  is  the  Entomobryidae.  However,  both 
the  Entomobryidae  and  Sminthuridae  have  20  species  represented. 

Because  trees  are  one  of  the  primary  constituents  of  a  community 
and  their  leaves  form  the  bulk  of  the  litter,  an  ordination  was  made  on

a  full  tally  of  the  trees  and  on  the  Collembola  of  each  area  to  determine 
if  there  is  a  relationship  between  the  two  populations.  The  data  were 
plotted  on  the  same  set  of  axes  (Figure  1).  The  interpoint  distances 
were  measured  graphically  from  the  trees  of  one  stand  to  the  Collembola 
of  the  same  stand  to  determine  the  degree  of  similarity  between  the  two 
populations.  In  lowest  terms  the  distances  are  as  follows:  old  field,  131 
units;  oak,  121  units;  maple-oak,  42  units;  and  beech-maple,  34  units. 
There  was  a  definite  straight  line  relationship  showing  that  the  distance

dissimilarity  between  the  two  as  measured  by  interpoint  distance, 
decreases  as  the  climax  area  is  approached  and  stability  is  reached.  In 
the  more  advanced  serai  stages,  the  maple-oak  and  beech-maple,  the  ordi- 
nation results  indicated  equilibrium  is  approached  between  the  woody 
vegetation  and  the  collembolan  population. 

When  the  Collembola  and  trees  were  ordinated  in  the  third  dimen- 
sion, the  Collembola  occurred  in  two  main  groups  with  respect  to  each 
other.  The  Collembola  of  the  wooded  areas  were  closely  grouped  together. 
Interpoint  distances  were  beech-maple  (BM)  to  maple-oak  (MO)  =  36.2; 
BM  to  oak  (0)  =  40.8;  and  MO  to  0  =  48.0.  When  each  wooded  area  was 
compared  to  the  old  field,  another  grouping  occurred.  Interpoint  distances 
were  BM  to  old  field  (OF)  =  134.2;  MO  to  OF  =  146.2;  and  0  to 
OF  =  151.7.  The  obvious  conclusion  is  that  the  collembolan  population 
of  the  wooded  areas  are  closely  related  to  each  other  while  the  collembolan 
population  of  the  old  field  is  a  separate  group. 


Summary 

1.  The  largest  numbers  of  Collembola  per  unit  volume  existed  in  the  oak 
area  and  the  smallest  numbers  in  the  old  field. 

2.  The  maple-oak  area  had  the  largest  number  of  species  (44)  while  the 
old  field  had  the  smallest  (20). 

3.  Isotobryoides  ochracius  and  Onychiurus  armatus  were  present  in  the 
highest  frequency  in  the  maple-oak  area. 

4.  The  most  important  species  in  terms  of  density,  frequency,  and 
prominence  value  was  Tomocerus  minor.  Second  was  Onychiurus 
armatus.  The  most  important  genera  are  Entomobrya,  Tomocerus, 
and  Onychiurus.   The  most  important  family  was  Entomobryidae. 

5.  Ordination  showed  that  the  similarity  between  the  collembolan  popu- 
lation and  the  tree  composition  in  each  area  increased  with  each 
succeeding  serai  stage;  the  greatest  similarity  was  found  in  the 
climax  beech-maple  area. 

6.  The  Collembola  in  wooded  areas  were  more  similar  to  each  other  than 
to  those  in  the  old  field.

Woodcock  Singing  Ground  Descriptions  for  Two  Indiana  Sites 

William  B.  Crankshaw,  Jerry  A.  Smith,  and  Ralph  D.  Kirkpatrick, 

Ball  State  University 

Abstract 

The  American  Woodcock,  Philohela  minor,  has  a  statewide  breeding-  dis- 
tribution in  Indiana.  While  conducting-  a  survey  of  woodcock  activity  on 
singing  grounds  in  the  spring  of  1968  we  found  that  singing  ground  cover 
requirements  were  more  comprehensive  than  anticipated.  Two  contrasting 
areas  were  selected  which  were  known  singing  grounds,  one  in  Randolph 
Co.  and  one  in  Delaware  Co.  The  Delaware  Co.  site  is  situated  in  cultivated 
fields  with  subdivisions  in  close  proximity.  The  Randolph  Co.  site  is  also 
in  a  cultivated  area  but  due  to  poor  drainage  the  site  proper  has  minimal 
disturbance.  No  subdivisions  are  located  near  the  Randolph  Co.  site.  A 
description  was  made  of  each  site  on  the  basis  of  vegetation,  soils,  drain- 
age, land  use  and  the  more  common  fauna. 

Introduction 

The  American  woodcock  {Philohela  minor)  has  a  statewide  breed- 
ing distribution  in  Indiana.  While  conducting  a  survey  of  woodcock  ac- 
tivity on  singing  grounds  during  April  and  May  1968,  we  noted  that 
singing  ground  cover  requirements  appeared  to  be  quite  broad.  A  search 
of  the  literature  revealed  no  descriptions  of  singing  grounds  in  Indiana. 

Study  areas  in  Delaware  and  Randolph  Counties  were  chosen  after 
woodcock  were  known  to  be  using  them  as  singing  grounds.  Field  work 
was  conducted  during  June. 

Delaware  County  Study  Area 

The  site  chosen  for  the  following  description  was  considered  typical 
of  several  woodcock  singing  areas  located  north  of  Muncie  in  central 
Delaware  county.  The  site  is  located  at  T21N,  R9E,  Sec  25,  NE1^.  The 
general  area  is  one  of  rolling  cultivated  land,  with  occasional  small  wood- 
lots  and  scattered  subdivisions.  The  woodlots  are  generally  oak-hickory 
stands  with  a  brushy  understory  indicating  a  history  of  intensive  timber 
removal.  The  subdivisions  are  composed  of  one  story  homes  usually  on 
half  acre  lots  with  virtually  no  trees. 

The  site  surveyed  was  one  of  cultivated  fields  through  which  a  small 
dredged  stream,  Jake's  Creek,  flows  in  a  southwesterly  direction.  A  small 
stand  of  trees  is  located  approximately  three  hundred  yards  to  the  south 
of  the  stream.  The  singing  birds  had  been  heard  in  the  cultivated  fields 
north  of  and  adjacent  to  the  stream.  North  of  the  surveyed  area  is  a  com- 
plex of  old  farm  buildings  used  only  for  implement  storage.  North  of  the 
barns  and  across  a  road,  is  a  small  housing  development.  There  is  no 
evidence  of  livestock  pastured  in  the  singing  area.  The  land  use  for  the 
past  few  years  has  been  that  of  cash  grain  crops. 

Jake's  Creek  is  located  about  eight  feet  below  the  general  land 
level  due  to  dredging.  It  averages  about  six  feet  in  width,  is  relatively

deep  for  its  width,  has  a  low  turbidity  and  is  a  perennial  stream.  A 
strip  of  natural  vegetation  35  feet  on  each  side  parallels  the  creek 
channel. 

The  soils  represented  in  the  singing  area  are  of  the  Morley-Blount- 
Pewamo  series. 

The  cultivated  fields  on  both  sides  of  the  stream  have  been  under 
apparently  continuous  crop  cover  for  some  years  with  soybeans,  wheat, 
oats,  and  corn  evident  this  current  year.  The  strip  along  the  stream 
was  composed  of  small  trees,  shrubs,  and  herbaceous  plants.  The  dom- 
inant plant  of  the  herbaceous  species  was  Redtop  {Agrostis  vulgaria); 
dominance  was  shared  in  the  woody  plants  by  several  species.  The  fol- 
lowing is  a  list  of  the  woody  plants  present  on  the  surveyed  area:  Black 
walnut  (Juglans  nigra),  Pignut  hickory  (Carya  glabra),  Shagbark 
hickory  (Carya  ovata),  Hackberry  (Celtis  occidentalis) ,  White  ash  Haw- 
thorn (Crataegus  spp.) ,  Red-osier  dogwood  (Cornus  stolo?iifera) ,  Honey- 
locust  (Gleditsia  triacanthos) ,  Black  willow  (Salix  nigra),  Boxelder 
(Acer  negundo),  Bur  oak  (Quercus  macrocarpa) ,  and  Smooth  sumac 
(Rhus  glabra).  The  herbaceous  plants  were:  Redtop  (Agrostis  alba), 
Wild  parsnip  (pastinaca  sativa) ,  Wild  carrot  (Daucus  carota) ,  Common 
ragweed  (Ambrosia  trifida),  Red  clover  (Trifolium  erectum) ,  Dandelion 
(Taraxacum  officinale),  Chicory  (Cichorium  intybus) ,  Common  milkweed 
(Asclepias  syriaca) ,  Wild  rose  (Rosa  virginiana),  Burdock  (Arctium 
lappa),  Horseweed  (Erigeron  canadense) ,  Common  thistle  (Cirsium 
lanceolatum) ,  Canada  thistle  (Cirsium  arvense) ,  Teasel  (Dipsacus  syl- 
vertria),  Wild  morning  glory  (Ipomoea  spp.),  Sweet  clover  (Melilotus 
alba  and  M.  officinalis),  Poison  ivy  (Toxicodendron  radicans) ,  Wild 
lettuce  (Lactuca  canadensis),  Dock  (Rumex  spp.),  Green  foxtail  (Seta- 
ria  viridis),  Timothy  (Phleum  pratense) ,  Moth  mullein  (Verbascum  blat- 
taria) ,  and  Great  mullein  (Verbascum  thapsus) . 

The  birds  listed  were  actually  seen  while  some  of  the  animals  were 
included  on  the  basis  of  various  indications  of  their  presence.  The  birds 
observed  were:  mourning  dove  (Zenaidura  macroura) ,  purple  martin 
(Progne  subis  subis),  barn  swallow  (Hirundo  rustica  ery throg aster) , 
bank  swallow  (Riparia  riparia  riparia) ,  goldfinch  (Spinus  triatis  tria- 
tis) ,  redwing  (Agelaius  phoeniceus) ,  sparrow  (Passer  domesticus  do- 
mesticus) ,  bronzed  grackle  (Quiscalus  versicolor) ,  and  bobwhite  (Colinus 
virginianus) .  The  mammals  observed  or  which  gave  evidence  of  their 
activities  were:  deer  mouse  (Peroynyscus  leucopus) ,  meadow  mouse 
(Microtus  pennsylvanicus) ,  muskrat  (Ondatra  zibethica) ,  woodchuck 
(Marmota  monax) ,  and  raccoon  (Procyon  lotor) . 

Randolph  County  Study  Area 

Cabin  Creek  Bog  was  the  location  of  a  woodcock  singing  ground 
in  Randolph  county.  The  bog  is  located  about  500  feet  south  of  Cabin 
Creek  on  Indiana  State  Hwy.  #1.  The  topography  of  the  region  is  rolling 
with  several  smaller  bogs  nearby.  The  Cabin  Creek  Bog  was  selected  due 
to  the  contrast  it  presents  to  the  site  described  in  Delaware  county.  The 


Ecology  243 

bog  is  elevated  above  the  general  terrain  and  perennial  springs  flow 
from  its  highest  points.  The  area  surrounding  the  bog  is  farmland  of 
moderate  quality  mainly  in  the  U.  S.  Soil  Conservation  Service  Land 
Capability  Classes  of  III  and  IV.  Woodcock  have  been  observed  singing 
and  nesting  in  the  bog  proper  for  many  years. 

The  soil  is  peaty,  probably  Rifle  peat,  and  very  unstable  to  walk 
upon.  The  soil  in  the  bog  stays  wet  throughout  the  summer  as  evi- 
denced by  the  many  springs  flowing  from  the  bog. 

The  more  dominant  plants  in  the  bog  are  given  here.  On  the  west- 
ern side,  above  a  marshy  border  of  Carex  spp.,  Juncus  spp.,  and  Skunk 
cabbage  (Symplocarpus  foetida)  the  dominants  are  mainly  prairie  plants 
and  occur  in  the  open.  This  area  is  covered  with  small  hummocks  formed 
by  plant  roots  and  peat,  the  most  prevalent  plant  appears  to  be  Prairie 
dock  (Silphium  terebinthinaceum)  and  several  grasses,  Big  and  Little 
Bluestem  (Andropogon  gerardii  and  A.  scoparins) ,  Indian  grass  (Sor- 
ghastrum  nutans),  and  Panic  Grass  (Panicum  implicatum) .  The  center 
of  the  bog,  used  by  nesting  woodcocks,  is  the  location  of  groves  of  small 
trees  and  shrubs  that  have  formed  an  overstory.  The  main  plants  of 
this  area  are  Ninebark  (Physocarpus  opulfolius)  and  Quaking  aspen 
(Populus  tremuloides) .  A  large  variety  of  other  shrubs  and  trees  occupy 
this  area  in  association  with  the  aspen  and  Ninebark.  There  are:  Dog- 
wood (Cornus  stolonifera  and  C.  obliqua) ,  Sumac  (Rhus  vernix) ,  Buck- 
thorn (Rhamus  laceolata) ,  Viburum  (V.  lantago) ,  Willow  (Salix  spp.) 
and  Hazelnut  (Corylus  americana) .  East  of  the  bog  center  is  another 
open  area  dominated  by  the  Shrubby  cinquefoil   (Potentilla  fructicosa) . 

The  mammals  of  the  area  include  the  meadow  jumping  mouse 
(Zapus  hudsonius),  shorttail  shrew  (Blarina  brevicanda) ,  eastern  mole 
(Scalopus  aquaticus),  and  the  red  fox  (Vulpes  fulva).  Birds  observed 
include  bronzed  grackle  and  flicker  (Colaptes  auratus) . 


Discussion  and  Conclusions 

Delaware  County  singing  ground  surveyed  was  selected  because  it 
was  very  typical  of  the  other  singing  grounds  in  east-central  Indiana. 
It  had  relatively  little  cover  and  was  located  in  the  proximity  of  houses. 
Some  of  the  other  singing  grounds  in  the  country  were  situated  between 
subdivisions  with  houses  located  within  two  hundred  feet  in  either  direc- 
tion. There  was  some  evidence  of  a  correlation  between  soil  types  and 
woodcock  breeding  areas.  Most  of  the  breeding  grounds  were  located  on 
Pewamo  silty  clay  loams.  This  soil  type  has  a  high  moisture  holding 
capacity;  in  Delaware  county  it  is  generally  artificially  drained. 

The  Randolph  County  singing  ground  is  relatively  undisturbed  by 
agricultural  activities.  There  is  open  space  as  is  required  for  singing 
grounds  (2,  3)  as  well  as  a  soft  soil  suitable  for  probing  for  food.  Scat- 
tered shrubs  are  present  as  Marshall  (1)  found  on  Minnesota  singing 
grounds.

The  American  woodcock  is  apparently  not  uncommon  in  east-central 
Indiana.  Its  singing  grounds  are  located  in  cover  types  that  are  very 
extensive  as  well  as  in  some  unusual  less  extensive  types.

Hemmer  Woods :  An  Outstanding  Old-Growth  Lowland  Forest 
Remnant  in  Gibson  County,  Indiana 

M.  T.  Jackson,  Indiana  State  University 

Interest  in  old-growth  forest  stands  and  other  little-disturbed 
remnants  of  original  Indiana  vegetation  has  been  heightened  by  the 
current  Indiana  Natural  Areas  Survey.  More  commonly  than  not,  areas 
that  have  escaped  the  major  causes  of  disturbance  are  founa  by  ecologists 
to  be  either  extremely  inaccessible  or  on  marginal,  rugged  land  that 
has  precluded  clearing.  Hemmer  Woods  is  a  welcome  exception.  The 
Hemmer  family  has  preserved  this  nearly  level  lowland  forest  remnant 
because  of  their  love  for  large  trees  and  quiet  woods.  The  central  pur- 
pose of  this  paper  is  to  provide  a  detailed  description  of  this  remarkable 
old-growth  forest  stand  before  it  is  ' 'developed"  into  one  of  the  all-too- 
common  land  use  patterns  of  the  state. 

Location  and  Description  of  the  Area 

Hemmer  Woods  is  located  about  two  miles  southeast  of  the  village 
of  Mackey  in  extreme  southeastern  Gibson  County.  The  area  is  in  the 
Wabash  Lowland  Physiographic  Province  that  was  subjected  to  glacia- 
tion  during  the  Illinoian  Period.  Smith  Fork  of  Pigeon  Creek,  which  is, 
in  turn,  tributary  to  the  Ohio  River,  meanders  through  the  entire  length 
of  the  area.  The  least  disturbed  section  of  the  woods  comprises  about  20 
acres  located  principally  in  the  North  Half  of  the  Northwest  Quarter  of 
the  Southwest  Quarter  of  Section  24,  Township  3  South,  Range  9  West. 
Another  nearby  wooded  tract  of  about  70  acres  is  also  owned  by  the 
Hemmers.  This  large  stand  has  had  slight  disturbance  by  limited  cuting 
several  years  ago.  Although  a  description  of  the  latter  stand  is  not  in- 
cluded in  this  paper,  it  should  be  the  site  of  future  ecological  studies 
because  it  represents  a  gradual  transition  from  the  floodplain  to  the  dry 
upland. 

The  study  area  is  part  of  an  alluvial  deposit  known  locally  as  the 
"Buckskin  Bottoms."  The  area  has  less  than  10  ft  of  relief  with  the 
entire  20-acre  stand  lying  between  410  and  420  ft  above  mean  sea  level. 
The  soil  type  was  mapped  in  the  1922  Gibson  County  Soil  Survey  Report 
as  Waverly  silt  loam.  It  has  a  light  gray  surface  horizon  that  is  medium 
in  organic  content.  Soil  samples  taken  from  six  locations  ranged  from 
pH  6.0  to  6.2.  The  area  was  naturally  poorly  drained,  owing  to  its  flat 
surface,  low  position  and  gentle  stream  gradient.  A  deeply-dredged  ditch 
located  a  few  rods  from  the  stand  has  lowered  the  water  table  until  the 
section  of  the  creek  that  is  located  within  the  stand  remains  very  low 
or  dry  during  most  of  the  year.  According  to  Mr.  L.  H.  Hemmer,  the 
ditch  was  dug  in  1918,  and  prior  to  that,  the  creek  retained  a  good  flow 
of  water  all  year. 

No  living  trees  have  been  removed,  but  dead  individuals  have  been 
cut  following  lightening   strikes   or  other   natural   mortality.   A   small 

245 


246  Indiana  Academy  of  Science 

tornado  struck  the  southern  edge  of  the  stand  in  1916  and  several  wind- 
thrown  and  damaged  trees  were  salvaged  shortly  thereafter.  Mr.  Hem- 
mer  states  that  there  has  been  no  fire  in  the  stand  during  this  century 
and  grazing  has  been  excluded  since  World  War  I  or  earlier.  There  is 
no  present  evidence  of  disturbance  except  for  a  very  few  stumps  that 
remain  from  past  cutting  of  dead  trees.  The  area  has  been  designated 
as  a  classified  forest  for  about  20  years  by  the  Indiana  Division  of 
Forestry. 

Procedure 

A  full  census  was  made  by  the  usual  full  tally  method  for  11.33  acres 
centered  in  the  main  part  of  the  stand.  All  stand  edges  were  excluded. 
The  major  study  section  (600  ft  square)  is  located  in  the  main  east-west 
part  of  the  tract.  A  smaller  contiguous  section  (roughly  a  30°-60°  tri- 
angle with  a  400  ft  base)  was  tallied  in  the  northeastern  part  of  the 
stand.  Temporary  markers  will  be  replaced  by  permanent  stakes  at  the 
plot  corners.  All  trees  over  4  inches  dbh  (diameter  breast  high)  were 
measured  to  the  nearest  one  tenth  inch  with  diameter  tapes  and  those 
2.0  to  3.9  inches  were  counted  and  recorded  by  species.  Tree  heights  were 
taken  with  an  Abney  level. 

Since  the  area  has  quite  uniform  topography,  the  section  tallied  is 
treated  as  a  single  stand.  The  tally  for  one  small  segment  of  the  stand 
which  is  located  on  slightly  higher  ground  was  recorded  separately  and 
is  discussed  later.  Data  are  summarized  in  Tables  1  and  2.  Stand  attri- 
butes are  those  of  Lindsey  (2);  species  nomenclature  for  trees  follows 
Little  (5);  and  shrub  and  herb  nomenclature  follows  Fernald  (1).  Com- 
mon names  of  trees  are  used  in  the  text  for  convenience  in  reading. 

Stand  Description 

A  total  of  1,259  trees  were  tallied  in  the  size  classes  greater  than 
4.0  inches.  The  2.0  to  3.9-inch  size  class  contained  789  individuals,  in- 
cluding 28  vines  which  are  omitted  from  the  tables.  As  indicated  in 
Table  1,  the  stand  is  of  mixed  lowland  composition  with  several  species 
sharing  dominance.  Thirty-two  species  were  represented  by  individuals 
larger  than  4  inches  dbh,  and  eleven  species  had  importance  values  of 
nearly  5%  or  greater.  It  is  best  characterized  as  a  sweet  gum — tulip- 
poplar — red  maple — elm  stand.  The  presence  of  tulip-poplar  as  one  of 
the  dominant  species  in  this  lowland  stand  is  understandable  when  one 
considers  that  Ridgway  (6)  found  the  species  growing  to  great  pro- 
portions in  the  original  forests  of  the  fertile  high  bottoms  of  the  southern 
Wabash  River  floodplain.  The  low  gradient  stream  of  this  stand  has 
probably  never  flooded  extensively  for  lengthy  periods,  conditions  similar 
to  those  on  the  Wabash  high  bottoms.  Lindsey,  ct  al.  (4),  failed  to  find 
tulip-poplar  present  in  the  Wabash  floodplains,  since  complete  clearing 
for  agriculture  had  removed  most  of  the  suitable  sites.  Increased  fre- 
quency and  duration  of  flooding  in  recent  decades  undoubtedly  has  ac- 
celerated the  loss  of  species  such  as  tulip-poplar,  which  are  relatively 
intolerant    to    inundation.    Hemmer    Woods    has    increased    value    as    a 


Ecology  247 

natural  area  since  it  is  the  only  known  example  of  floodplain  forest  in 
the   state  that  includes   such   large   tulip-poplar  trees. 

The  size  of  individual  trees  and  the  great  number  of  large  trees 
are  the  most  striking  features  of  the  stand  (Table  2).  Eleven  species 
have  a  total  of  74  individuals  in  the  30-inch  or  larger  size  classes,  for 
an  average  of  over  six  30-inch  plus  stems  per  acre.  Eighteen  stems 
greater  than  40  inches  dbh  fell  within  the  study  plot.  At  least  three  trees 
greater  than  40  inches  fell  outside  the  plot,  including  a  48.3  inch  syca- 
more. Three  tulip-poplars  exceeded  50  inches  dbh;  the  largest,  at  54.6 
inches,  may  be  the  largest  individual  of  that  species  in  the  state.  Twelve 
species  had  representatives  larger  than  30  inches  with  sycamore  48.6 
inches,  white  oak  44.0,  sweet  gum  40.7,  green  ash  37.4,  red  oak  36.5, 
American  elm  35.9,  red  maple  34,4,  hackberry  33.5,  river  birch  30.8  and 
swamp  white  oak  30.5.  The  stand  is  also  noteworthy  for  large  sassafras 
(nine  over  20  inches)  with  the  largest  at  31.9.  A  great  number  of  the 
larger  trees  have  clear  boles  of  40  to  60  feet.  The  largest  tulip-poplar 
measured  151  feet  tall  and  53  feet  to  the  first  limb.  The  larger  tulip 
trees  stand  20  to  30  feet  taller  than  the  general  canopy  level  of  about 
120  feet.  Another  interesting  feature  is  the  large  grove  of  very  large 
paw  paw  trees.  Twenty  paw  paw  stems  exceeded  4  inches  dbh  with  two 
reaching  6.2  inches.  These  are  among  the  largest  forest  grown  paw  paw 
trees  that  the  author  has  measured. 

The  shrub  stratum  is  dominated  by  Lindera  benzoin,  Staphylea  tri- 
folia,  Euonymns  afj'opurpureus,  and  Smilax  rotundifolia.  Urtica  pro- 
cera  abounds  in  the  herb  layer,  which  could  aid  in  the  preservation  of 
the  area!  Mr.  Hemmer  stated  that  the  spring  wildflower  display  is 
very  showy,  including  large  colonies  of  Trillium  gleasoni  and  Mertensia 
virginica. 

Effect  of  Drainage  on  Stand  Composition 

Although  there  is  little  relief  within  the  area,  there  is  remarkable 
ecological  separation  of  species  that  are  usually  restricted  to  either  up- 
land or  lowland  sites.  Along  such  a  low  gradient  stream,  three  or  four 
vertical  feet  alter  the  drainage  and  soil  moisture  patterns  appreciably. 
Since  several  of  the  tally  strips  crossed  the  area  at  right  angles  to  the 
stream,  it  was  easy  to  note  the  gradual  but  definite  species  shift  to 
species  less  tolerant  of  high  water  tables  as  the  gentle  topographic  rise 
was  topped.  This  helps  explain  the  presence  of  shagbark  and  mockernut 
hickory,  and  black  oak  in  the  same  stand  with  swamp  white  oak,  syca- 
more, river  birch,  sweet  gum,  hackberry  and  shellbark  hickory. 

Another  interesting  moisture  relationship  is  illustrated  by  a  com- 
parison between  the  species  importance  values  of  a  small  segment  (ap- 
proximately 1  acre)  of  the  stand  located  on  the  highest  small  rise  with 
importance  values  of  the  main  stand.  This  small  segment,  on  a  gentle 
southwest-facing  slope,  had  a  combined  importance  value  for  the  more 
typically  upland  oaks  (white,  red  and  black)  and  upland  hickories  (shag- 
bark  and  mockernut)  of  30.9%  as  compared  to  11.6%  for  the  same 
species  in  the  remainder  of  the  stand.  A  change  in  importance  value  of

nearly  20%  for  these  species  indicates  much  lower  soil  moisture  levels 
on  the  slope.  In  addition,  the  only  individual  of  the  most  xeric  of  the 
oak  species  present  (black  oak)  was  found  on  the  same  slope. 

Other  species  with  substantial  shifts  in  importance  in  the  slope 
segment  include:  a)  increases  on  slope;  slippery  elm  6.3%  to  12.3%, 
white  ash  2.8%  to  8.1%,  wild  cherry  1.4%  to  6.0%  and  sassafras  5.9% 
to  10.4%) ;  b)  decreases  on  slope;  sweet  gum  14.0%  to  3.8%,  red  maple 
8.7%  to  0.6%,  American  elm  7.9%  to  2.4%,,  hackberry  7.6%  to  3.8%, 
sycamore  6.0%  to  0.0%,  shellbark  hickory  2.2%  to  0.0%  and  river  birch 
1.5%  to.  0.0%.  It  is  of  interest  that  all  species  with  increases  in  im- 
portance are  more  typical  of  upland  stands,  while  all  species  with  de- 
creases in  importance  are  typical  of  depressional  or  floodplain  situations. 

Of  the  five  sugar  maples  larger  than  4.0  inches,  three  were  in  the 
slope  segment.  Four  of  the  sugar  maples  were  in  the  6-inch  size  class 
with  the  lone  exception  at  13.3  inches.  One  4.9  inch  sugar  maple  was 
found  on  a  very  slight  rise  along  the  creek  and  another  at  6.6  inches 
occurred  on  higher  ground  near  the  south  edge  of  the  stand.  Both  of 
the  2-4  inch  maples  occurred  on  higher  sites.  Only  a  single  red  maple 
was  found  on  the  slope,  as  compared  to  an  average  of  12.7  red  maples  per 
acre  in  the  remainder  of  the  stand. 

Future  Changes  in  Composition 

Perhaps  the  shift  from  red  maple  to  sugar  maple  on  the  drier  sites 
is  a  definitive  change  that  portends  a  future  trend  within  the  stand 
toward  species  less  typical  of  floodplains.  This  could  indicate  the  begin- 
ning of  a  species  shift  in  response  to  less  hydric  conditions  following  the 
lowering  of  the  water  table  50  years  ago. 

Inspection  of  the  size  class  data  in  Table  2  reveals  that  several 
species  seem  to  be  shifting  significantly  in  importance  value.  Both  river 
birch  and  sycamore  are  restricted  to  the  immediate  vicinity  of  the  creek 
bank  and  neither  is  reproducing.  Although  tulip-poplar  has  more  general 
distribution  throughout  the  stand,  apparently  it  is  not  reproducing.  One 
could  assume  that  it  will  be  maintained  in  canopy  openings  resulting  from 
windthrow  or  death,  since  abundant  seed  sources  are  at  hand.  There  are 
few  tuilp  trees  in  the  area  disturbed  by  the  tornado,  however.  Instead, 
other  intolerant  species  such  as  sassafras,  wild  cherry,  slippery  elm, 
American  elm  and  hackberry  represent  a  larger  percentage  of  the 
medium-sized  stems  in  that  area. 

When  ratios  of  the  number  of  individuals  smaller  than  12  inches  to 
the  number  of  individuals  greater  than  12  inches  are  compared  for 
several  species,  projected  compositional  changes  become  clearer.  The 
three  members  of  the  Ulmaceae  plus  red  maple  have  ratios  greater  than 
3:1  and  seem  to  be  invading  the  stand  rapidly.  Wild  cherry,  ash,  black 
gum,  bitternut  and  shagbark  hickory  have  ratios  decreasing  from  2:1  to 
%:1  in  the  order  listed.  These  species  seem  to  be  maintaining  their 
position  in  the  stand.  River  birch,  sweet  gum,  tulip-poplar,  white  oak, 
shellbark  hickory  and  sycamore  have  ratios  less  than  0.5:1  and  appear

to  be  losing  their  share  of  stand  dominance.  The  size  distribution  ratios 
are,  at  best,  only  indications  of  trends,  since  they  do  not  completely  ac- 
count for  differential  survival  rates  among  young  trees  of  different 
species. 

Since  the  number  of  standing  dead  trees  per  species  gives  some  in- 
formation about  survival  rates,  all  identifiable  dead  trees  were  measured 
and  recorded.  Overall,  4.4%  of  the  total  standing  stems  were  dead.  This 
appears  to  be  a  relatively  low  mortality  rate  until  one  considers  that 
most  small  trees  are  largely  sapwood  which  decays  to  a  condition  that 
precludes  species  identification  in  a  very  few  years.  Dead  trees  repre- 
sented a  substantial  percentage  of  total  standing  stems  for  the  follow- 
ing species:  sassafras  12.1,  black  cherry  9.7,  American  elm  8.6,  black 
gum  6.0,  sweet  gum  4.2  and  slippery  elm  3.0.  American  elm  seems  to  be 
maintaining  its  position  in  the  stand,  since  widespread  mortality  from 
elm  diseases  is  not  in  evidence. 

The  stand  does  not  appear  to  be  at  climax  although  largely  un- 
disturbed by  man.  Perhaps  an  equilibrium  had  been  reached  prior  to 
drainage.  Presently  the  composition  shift  appears  to  be  favoring  species 
typical  of  situations  of  medium  soil  moisture.  Those  species  favoring 
very  moist  situations,  such  as  river  birch,  sweet  gum,  shellbark  hickory 
and  sycamore,  are  apparently  decreasing.  Windthrow  has  probably  helped 
retain  intolerant  species  such  as  wild  cherry,  sassafras  and  tulip-poplar. 
It  is  of  interest  that  no  beech  trees  were  found  in  any  size  class,  al- 
though beech  occurs  quite  commonly  in  surrounding  stands.  Perhaps  the 
relatively  recent  invasion  of  sugar  maple  is  the  initial  step  toward  a 
beech-maple  dominated  stand,  and  that  beech  invasion  will  follow  suit 
in  the  future.  Long  term  studies  would  be  of  interest  here. 

Comparison  with  Other  Stands 

Bottomland  and  depressional  forests  frequently  have  higher  basal 
area  per  acre  than  most  undisturbed  upland  stands  which  partially 
explains  the  moderately  high  (134  sq  ft  per  acre)  basal  area  in  this 
stand.  It  is  surpassed  in  basal  area  by  only  four  of  the  old-growth  stands 
reported  by  Schmelz  and  Lindsey  (7).  It  has  both  higher  basal  area  and 
lower  density  per  acre  than  either  Donaldson's  Woods  in  Lawrence 
County  or  Cox  Woods,  Orange  County,  which  are  often  considered  to  be 
the  most  impressive  forests  in  the  state  (7).  Beckville  Woods  in  Mont- 
gomery County,  which  occupies  a  depressional  Brookston  silt  loam  soil, 
was  found  by  Petty  (personal  communication)  to  have  135  sq  ft  per 
acre.  A  full  tally  of  21  acres  of  Kramer  Woods  along  the  Ohio  River 
in  Spencer  County  was  found  by  Schmelz  (personal  communication)  to 
have  128.5  sq  ft  per  acre,  but  the  stand  density  was  much  lower  at  78.9 
trees  per  acre.  The  mean  diameter  of  trees  in  Hemmer  Woods  at  12.2 
inches  is  about  average  for  old-growth  stands  in  the  state,  but  Kramer 
Woods  at  14.6  and  Beall  Woods  at  14.2  (7)  indicate  a  greater  percentage 
of  large  trees. 

When  the  numbers  per  size  class  were  plotted  on  semi-log  paper 
according  to  the  method  used  by  Schmelz  and  Lindsey    (7)    to  analyze

disturbance  in  stands,  the  relationship  approaches  a  straight  line  more 
closely  than  did  any  of  the  19  stands  that  they  studied.  Slight  plateaus  in 
the  18  to  26-inch  size  classes  and  42  to  50-inch  size  classes  indicate  only 
mild  disturbance.  The  former  plateau  probably  reflects  the  windthrow  of 
52  years  ago. 

Hemmer  Woods  has  18  of  its  32  species  in  common  with  the  Beall 
Woods  bottomland  stand  which  is  located  on  the  larger  floodplain  of  the 
lower  Wabash  River  (3),  and  24  of  its  32  species  in  common  with  Kramer 
Woods.  Most  important  Beall  Woods  species  absent  from  Hemmer 
Woods  are  bur  oak,  silver  maple,  and  pin  oak.  Shumard's  oak  repre- 
sented 13%  of  Beall  Woods,  but  had  only  0.11%  importance  in  Hemmer 
Woods.  Although  pin  oak  is  absent  from  the  stand  reported  herein, 
it  is  abundant  in  medium  size  classes  in  the  larger  Hemmer  Woods 
stand.  Of  the  important  species  in  Kramer  Woods,  only  southern  red 
oak,  swamp  chestnut  oak  and  beech  are  absent  here.  Again,  Shumard's 
oak  is  very  important  (23%)  in  Kramer  Woods. 

Coefficients  of  community,  based  on  importance  percentages,  were 
calculated  to  compare  the  degree  of  similarity  among  the  three  bottom- 
land stands.  Hemmer  Woods  was  39.6%  and  32.8%  similar  to  Beall  and 
Kramer  Woods,  respectively.  Beall  and  Kramer  Woods  were  48.1% 
similar  to  one  another.  These  values  indicate  that  stands  located  on  flood- 
plains  of  larger  rivers,  within  a  given  area,  tend  to  be  more  similar  struc- 
turally than  are  stands  which  are  located  on  floodplains  of  large  and 
small  streams,  respectively.  Differences  in  the  frequency  and  duration 
of  flooding  between  large  and  small  streams  is  undoubtedly  a  major 
factor  influencing  stand  composition. 

The  only  species  of  southern  affinity  in  this  stand  are  persimmon  and 
Shumard's  oak,  although  floodplains  normally  offer  excellent  migration 
corridors. 

The  extremely  large  trees,  excellent  size  class  distribution,  rich 
species  composition,  high  basal  area  and  relatively  low  density  combine 
to  make  Hemmer  Woods  one  of  the  finest  forests  in  Indiana.  The  area 
is  certainly  of  the  quality  that  should  be  preserved  as  part  of  the 
Natural  Areas  System  of  Indiana.

E.  J.  and  L.  H.  Hemmer  for  permission  to  do  the  study.

A  Japanese  Weevil  Discovered  in  Indiana. 

Donald  L.  Schuder,  Purdue  University. — An  infestation  of  adult  Jap- 
anese weevils,  Pseudocneorhinus  bifasciatus  Roelefs,  was  reported1  by 
a  homeowner  in  Vincennes  on  June  26,  1968.  (The  owner  had  noticed  the 
insect's  damage  in  1967.)  Investigation  revealed  adults  to  be  common  in 
a  V2  city  block  area  and  causing  foliar  damage  to  mock  orange,  privet, 
rose,  spirea  and  weigela  and  other  shrubs. 

This  weevil,  native  to  Japan,  was  first  reported  in  the  U.  S.  in 
1923  in  Connecticut.  It  is  now  known  from  Delaware,  Georgia,  Maryland, 
New  Jersey,  New  York,  North  Carolina,  Pennsylvania,  South  Carolina, 
Virginia  and  the  District  of  Columbia,  on  the  eastern  coast  of  the  United 
States.  The  Indiana  record  is  the  first  report  from  the  midwest. 

The  host  list  of  this  omnivorous  pest  is  extensive  and  includes  the 
following  trees,  shrubs,  flowers,  fruit  and  vegetables:  Ash  (white),  citrus 
sp.,  elm,  hackberry,  hemlock,  mimosa,  oak,  azalea,  barberry  (Japanese), 
deutzia,  camelia,  clematis,  firethorn,  forsythia,  honeysuckle,  ivy  (Eng- 
lish), lilac,  mahania,  mock  orange,  mountain  laurel,  privet  (California 
and  Regels),  rhododendron,  rose,  rose  of  Sharon,  spirea  (Anthony  Water- 
er,  vanhoutte),  weigela,  ageratum,  chrysanthemum,  fern,  geranium,  hi- 
biscus, lilly-of-the-valley,  veronica,  lima  beans  and  strawberry.  The  insect 
occurs  in  large  numbers  and  cuts  broad,  rounded  sections  from  the 
margins  of  the  leaves  resulting  in  a  crenulated  appearance.  Injury  can 
be  extensive  and  death  of  hemlocks  and  rose  bushes  has  been  reported. 
The  insect  feeds  in  the  daytime. 

The  weevil  is  parthenogenetic  and  the  wing  covers  are  fused  so 
that  it  cannot  fly.  It  is  robust,  grey  in  color  and  the  elytra  are  crossed 
by  two  blackbands.  Adults  are  present  from  early  June  until  freezing 
weather.  Eggs  are  laid  in  partially  eaten,  curled,  dried  leaves.  The 
immature  stages  are  unknown. 

Because  of  its  omnivorous  habits  this  insect  constitutes  a  serious 
threat  to  the  ornamental  plantings  in  homeyards,  cemeteries,  golf 
courses,  strawberry  plantings  and  commercial  nurseries.  It  can  be  con- 
trolled with  early  applications  of  2.5  percent  aldrin,  dieldrin,  heptachlor, 
malathion  or  parathion  dusts  according  to  Smith  (J.  Econ.  Ent.  48:  628). 


1  The  infestation  was  reported  to  Robert  Dolphin  of  the  U.S.D.A.  stationed 
at  Vincennes.  Identification  was  made  by  Rose  Ella  Warner  of  the  U.  S.  National 
Museum.

A  Checklist  of  the  Mosquitoes  of  Indiana  with  a  Record  of  the 
Occurrence  of  Aedes  infirmatus  D&K 

John  W.  Hart,  Richmond,  Indiana 

The  first  record  of  a  mosquito  from  Indiana  was  published  in  1827 
when  Thomas  Say  (8)  described  Culex  musicus  [=Psorophora  ferox 
Humb.].  There  were  apparently  no  further  writings  listing  mosquitoes 
for  95  years.  Dyar's  1922  publication,  The  Mosquitoes  of  the  United 
States,  (4)  listed  another  four  species. 

In  1942  the  author  prepared  a  manuscript  entitled  "Preliminary 
Studies  of  the  Mosquitoes  of  Indiana"  in  partial  fulfillment  of  the  re- 
quirements for  a  degree  at  Purdue  University.  In  July  and  August  of  the 
same  year,  the  author  worked  in  Indiana  in  the  Malaria  Control  in  War 
Areas  (MCWA)  Program  of  the  U.  S.  Public  Health  Service.  Mosquito 
records  gained  as  a  result  of  both  of  these  studies  were  reported  in  a 
preliminary  list  of  Indiana  mosquitoes  (5).  This  1944  paper  noted  24 
species  known  to  occur  in  the  state. 

Christensen  and  Harmston  also  published  a  preliminary  list  of  the 
mosquitoes  of  Indiana  in  1944  (3).  They  reported  species  collected  in  the 
1941  and  1942  MCWA  studies  and  included  five  not  in  the  author's  list. 
Carpenter  reporting  on  collection  of  mosquitoes  at  military  installations 
in  Indiana  during  1944  and  1945  added  two  to  the  list  (2),  and  Brooks 
reported  another  in  1947  (1). 

The  next  13  records  were  added  by  Siverly  (9  thru  16),  Newhouse 
and  Siverly  (7),  and  Siverly  and  Burhardt  (17).  Two  additional  mos- 
quito findings  were  reported  in  1968,  one  by  Truman  and  Craig  (18), 
and  one  by  the  author  (6). 

This  paper  reports  Aedes  infirmatus  Dyar  and  Knab  not  previ- 
ously known  from  the  state.  The  Purdue  University  collection  contains 
an  excellent  female  specimen  taken  as  part  of  the  1958  studies  at  Hovey 
Lake  in  Posey  County.  Collection  date  was  August  20.

Orthopodomyia  signifera,  (Coq.)  and  O.  alba  Baker  are  indistin- 
guishable in  the  adult  stages.  Records  of  signifera  prior  to  Brooks  (1) 
were  based  on  adult  females.  Though  they  were  probably  correctly  called 
signifera,  a  positive  identification  can  not  be  claimed.  The  author  studied 
the  larval  material  collected  by  Brooks  and  concurred  in  the  identifica- 
tion of  both  species. 

The  occurrence  of  alba  in  Indiana  is  to  be  expected.  It  is  found  in 
reliable  lists  of  the  mosquitoes  of  both  Ohio  and  Illinois.

Crosses  of  Tropisternus  from  Central  America  with  Other  Color 

Forms  of  the  Tropisternus  collar  is  Complex 

(Colcoptera:   HYDROPHILIDAE) 

Frank  N.  Young,  Indiana  University 

In  several  previous  papers  (1,  3,  5)  different  color  forms  of  the 
Tropisternus  collaris  (Fabricus)  Complex  have  been  shown  to  be  cap- 
able of  interbreeding.  North  and  South  American  forms  readily  inter- 
breed and  produce  viable  offspring,  but  these  offspring  are  highly  in- 
fertile. The  principal  work  to  date  has  been  carried  on  with  a  melanic 
form  from  Lago  de  Ayapel,  Colombia,  and  the  three  North  American 
subspecies  (striolatus,  mexicanus,  and  viridis).  A  non-melanic  form  from 
Puerto  Rico  is  now  available,  and  some  of  the  previous  crosses  have  been 
repeated  with  it. 

The  melanic  form  from  Colombia  resembles  typical  collaris  from 
Brazil  and  Venezuela  in  the  basic  arrangement  of  the  elytral  pattern, 
but  has  the  elytral  dark  lines  expanded  so  that  in  some  individuals  the 
intermediate  areas  are  eliminated  and  the  elytra  appear  solid  green.  The 
pronotal  pattern  is  greatly  expanded  and  the  green  metallic  area  becomes 
broader  than  long  in  contrast  to  collaris  or  mexicanus.  The  head  pattern 
is  also  extended,  but  not  to  the  degree  seen  in  viridis  from  Florida, 
Georgia,  and  South  Carolina. 

In  contrast  the  usual  form  of  Tropisternus  collaris  found  in  Panama 
{mexicanus  Castelnau)  and  to  the  north  has  six  nearly  complete  dark 
lines  on  the  elytra  separated  by  areas  in  which  yellow,  fluorescent  pig- 
ments are  developed.  The  pronotal  pattern  is  similar  to  typical  collaris, 
and  the  dark  head  pattern  is  usually  reduced,  barely  or  not  extending 
anterior  to  the  Y-shaped  epicranial  suture. 

In  the  British  Museum  are  four  speciments  collected  by  Champion 
in  Panama  and  marked  "T.  collaris  var."  apparently  by  Sharp.  These 
were  apparently  not  included  in  the  Biologia  Americana  material  (2), 
unless  they  are  the  basis  of  the  citation  of  Panama  under  collaris  (2,  p. 
55).  T.  collaris  is  cited  from  Mexico  (collection  Saunders)  on  the 
basis  of  a  very  typical  specimen  which  is  almost  certainly  mislabelled 
and  probably  came  from  Venezuela.  The  four  Panama  specimens  col- 
lected by  Champion  have  the  elytral  lines  expanded  and  the  yellow 
pigments  largely  eliminated,  but  the  head  and  pronotal  markings  are 
much  as  in  typical  mexicanus.  I  believe  that  these  specimens  are  natural 
hybrids  between  the  melanic  form  of  collai^is  from  northern  Colombia 
and  the  subspecies  mexicanus  which  extends  throughout  Central  America 
and  northward  into  the  United  States.  Other  specimens  which  I  have 
seen  from  Panama  are  similar  to  typical  mexicanus. 

There  are,  however,  indications  in  several  series  from  Honduras, 
Guatemala,  Costa  Rica,  San  Salvador,  and  Panama  (collected  by  Kenneth 
Mc Williams    and    Borys    Malkin)    that    there    may    be    genes    from    the 

260 


Entomology  261 

melanic  form  which  have  flowed  northward.  Similar  lateral  extension  of 
the  dark  pronotal  blotch,  however,  is  completely  lacking  in  all  the 
northern  Mexican  specimens  I  have  seen  and  in  the  United  States  until 
the  zone  of  intergradation  between  mexicanns  and  striolatus  is  reached 
in  eastern  Texas,  Oklahoma,  Missouri,  and  Ilinois. 

It  was  hoped  that  the  probem  of  the  taxonomic  status  of  the  North 
and  South  American  forms  could  be  solved  by  laboratory  experiments  with 
the  Central  American  forms  and  the  laboratory  stock  from  Colombia.  In 
the  summer  of  1967,  Mr.  (now  Dr.)  Kenneth  McWilliams  collected  speci- 
mens for  me  in  several  countries  of  Central  America.  Unfortunately, 
specimens  from  Panama  died  in  transit,  but  specimens  from  Honduras 
and  Guatemala  arrived  alive  and  six  crosses  were  made  with  the  Colom- 
bian form  (AYA),  the  melanic  form  viridis  from  Florida,  and  between 
the  two  (Guatemala  female  x  Honduran  male).  Several  of  these  crosses 
proved  successful  and  174  adults  were  reared  from  376  larvae  (over 
47%). 

The  accompanying  tables  summarize  the  crosses,  backcrosses,  and 
outcrosses  made  to  test  the  fertility  of  the  parents  and  hybrids.  None  of 
the  Fi  x  Fi  crosses  nor  backcrosses  of  the  Honduran  x  Colombian  froms 
proved  fertile.  However,  when  Fi  hybrids  were  outcrosses  with  T.  c. 
viridis  from  South  Carolina  some  fertility  was  shown.  As  shown  in  the 
table,  this  was  low  and  many  deaths  occurred  in  the  larvae  before  the 
first  molt.  This  may  have  been  due  to  the  fact  that  all  of  the  males 
available  for  use  were  laboratory  reared  from  originally  natural  hybrids 
between  T.  c.  viridis  and  striolatus. 

The  result  of  these  crosses  indicate  that  there  is  still  a  very  high 
degree  of  infertility  in  the  Fx  of  hybrids  of  T.  c.  mexicanus  and  the 
melanic  form  from  Colombia  even  when  the  populations  are  closer  to- 
gether. The  distance,  however,  is  still  considerable  (over  900  miles), 
and  the  parent  populations  may  have  been  separated  for  a  considerable 
time.  It  still  seems  that  study  of  the  population  from  southern  Panama 
will  be  necessary  before  it  is  possible  to  declare  that  T.  collaris  and  T. 
mexicanus  (along  with  its  color  forms  striolatus  and  viridis)  are  specifi- 
cally distinct. 

The  color  patterns  in  these  crosses  have  not  yet  been  analyzed  in 
detail.  However,  they  follow  in  general  the  pattern  previously  noted  in 
crosses  between  the  melanic  Colombian  form  and  the  North  American 
forms,  that  is,  in  general  the  darker  patterns  are  recessive  to  the  lighter 
patterns,  but  there  are  differences  in  penetrance.  For  example,  the  head 
patterns  tend  to  be  slightly  more  extended  than  in  the  lighter  parent,  but 
not  as  extended  as  in  the  darker  parent.  Also,  there  is  a  persistent 
tendency  for  the  partial  expression  of  the  recessive  gene  in  the  presence 
of  the  full  expression  of  the  dominant  gene.  For  example,  in  the  cross  of 
Honduras  x  T.  c.  viridis  (Table  1,  5X)  all  offspring  showed  darker  elytra 
and  14  of  16  showed  a  more  extended  head  pattern  than  the  lighter 
female  parent.  (Unfortunately,  all  of  these  proved  very  feeble  and 
further  crosses  could  not  be  made.)

In  the  outcross  (Table  4,  24X,  25X,  26X)  of  the  Honduras  x 
Colombia  hybrid,  the  color  patterns  of  head,  pronotum,  and  elyta  show 
great  variation.  The  elytral  pattern  varies  from  lighter  than  the  lighter 
parent  to  darker  than  the  darker  and  the  head  and  pronotum  show  a 
similar  range.  Some  of  the  effects  in  this  cross  are  doubtless  due  to 
interacting  genes.  Some  individuals  from  this  cross  are  still  living,  but 
to  date  have  proven  highly  infertile  (Tabl  5,  31X,  32X).  I  wish  to  express 
my  thanks  to  Christina  Fenn  (now  Mrs.  Ronald  W.  Smith)  for  her 
assistance  in  this  research. 


Sunmmary  and  Conclusions 

The  low  degree  of  fertility  in  the  Fi  offsprings  of  Tropisternus  col- 
laris  mexicanus  from  Honduras  with  a  melanic  form  of  T.  collaris  from 
Colombia  suggests  that  these  populations  have  been  separated  for  a 
considerable  length  of  time.  The  lowered  fertility  is  about  of  the  degree 
that  is  found  in  crosses  of  the  other  North  American  forms  with  the 
South  American  or  West  Indian  forms.  Only  one  adult  was  obtained 
from  Fi  x  Fi  cross  and  none  from  backcrosses  with  the  Colombian 
parent.  Outcrosses  of  hybrids  with  the  melanic  T.  c.  viridis  from  South 
Carolina  indicates,  however,  that  the  hybrids  are  not  sterile  but  that 
their  failure  to  produce  viable  embryos  is  probably  due  to  lethal  genes 
and  possibly  translocations  which  cause  death  early  (or  later)  in 
development.

An  Annotated  List  of  the  Spiders  of  Indiana1 

Thomas  A.  Parker,  Purdue  University 

Introduction 

The  history  of  Indiana  araneology  began  in  1847  when  Nicholas 
Marcellus  Hentz,  the  Father  of  American  Araneology,  described  A  galena 
naevia  from  Indianapolis  (29).  Since  that  time  many  have  contributed  to 
the  list  of  spiders  of  Indiana.  Notable  among  these  contributions  are  the 
works  of  Fox  (25),  Banks  (2),  and  Elliott  (20,  21,  22). 

Dr.  William  H.  Fox  published  the  first  list  of  Indiana  spiders  (25), 
which  was  based  on  a  collection  of  a  chemistry  professor  at  Purdue  Uni- 
versity, Mr.  Frederick  C.  Test.  This  list  included  79  species  of  spiders  in 
what  would  today  be  16  families,  although  family  names  were  not  used  in 
this  list. 

Nathan  Banks  published  a  preliminary  list  of  Indiana  spiders  in 
1907  (2).  This  work  included  keys  to  the  families  and  genera  of  spiders 
and,  in  addition,  a  list  of  species  belonging  to  other  arachnid  orders.  The 
list  of  spiders  included  148  species  found  in  16  families,  two  species  of 
which  were  described  as  new  to  science.  The  list  was  based  on  spiders 
collected  by  W.  S.  Blatchley,  Mel  T.  Cook  of  Greencastle,  W.  J.  Moenkhaus 
of  Huntingburg,  and  A.  M.  Banta  who  collected  spiders  in  Indiana  caves. 

In  1930  the  late  Dr.  Frank  R.  Elliott  published  on  spiders  of  a  beech- 
maple  forest  near  Richmond,  Indiana  (20).  Combining  the  records  of 
Banks  with  newly  collected  material  and  his  beech-maple  study,  Elliott 
published  a  list  of  Indiana  spiders  in  1932  (21).  This  list  contained  218 
species  of  spiders  found  in  20  families. 

Elliott  again  published  a  list  of  Indiana  spiders  in  1953  (22).  It  was 
based  on  records  in  the  literature  and  newly  collected  material.  The  work 
of  Lowrie  (38,  39)  on  the  spiders  of  the  Chicago  area  dunes  greatly  con- 
tributed to  the  records  of  Indiana  spiders.  Using  these  records  and 
others,  Elliott  assembled  a  list  containing  303  species  of  spiders  found  in 
21  families. 

No  major  studies  of  the  spiders  of  Indiana  have  been  published  since 
Elliott's  1953  list.  This  paper,  then,  will  enlarge,  correct,  and  update  the 
list  of  Indiana  spiders. 

The  List 

The  present  list  of  Indiana  spiders  contains  378  species  of  spiders 
found  in  29  families.  The  families  are  arranged  following  the  system  used 
by  Kaston  (32).  The  genera  are  alphabetically  arranged  in  the  families 
and  likewise  the  species  in  the  genera.    Nomenclature  generally  follows 


1  Journal    Paper    No.    3771,    Purdue    University   Agricultural    Experiment 
Station.

that  used  by  Kaston.  Synonyms  are  included  beneath  the  accepted  scien- 
tific name  in  cases  where  name  changes  have  occurred  within  the  last 
twenty  years.  The  species  are  numbered  consecutively. 

Collection  records  are  arranged  by  county  with  the  oldest  record  pre- 
ceding all  others.  The  counties  are  in  bold-faced  type.  Usually  the  local- 
ity is  given  in  parenthesis,  followed  by  citations  in  which  the  record  was 
found.  In  instances  where  no  locality  was  given  in  the  literature  or  where 
recent  collectors  gave  no  specific  locality  on  their  labels,  just  the  citation 
or  date  collected  and  collector's  initials  are  included  in  the  parenthesis. 
If  the  record  is  a  recent  one,  the  collection  dates  and  collector's  initials 
are  included.    Names  of  collectors  may  be  found  in  Appendix  I. 

Many  of  the  localities  recorded  in  the  older  publications  no  longer 
exist,  having  been  incorporated  into  neighboring  cities.  Other  names 
appearing  in  the  literature  were  local  names  and  were  not  formally  recog- 
nized. Appendix  II  enables  the  reader  to  locate  such  places  more  accu- 
rately. Also  included  in  this  appendix  are  a  few  localities  visited  by  the 
author  or  his  colleagues  for  which  a  more  specific  geographical  description 
was  deemed  necessary. 

The  writer's  spider  collection  is  housed  in  the  Entomology  Depart- 
ment at  Purdue  University.  All  identifications  of  recent  collections  were 
made  by  the  writer.  Some  verifications  were  obtained  from  araneologists 
in  the  United  States  and  Canada.  Such  determinations  are  credited  to 
these  men  individually  in  the  text.  This  list  is  based  on  records  from  the 
literature  and  the  collection  of  the  writer.  This  collection  represents  spi- 
ders collected  during  a  three-year  study  of  spiders  along  the  Wabash  and 
Tippecanoe  Rivers,  spiders  sent  for  determination  through  the  Cooperative

Entomology  269 

The  Twin  Cave  record  of  Banks  is  from  a  specimen  sent  to  him  by 
Banta  and  probably  is  Banta's  "Lower  Twin  Cave  at  Mitchell"  which  is 
in  Lawrence  County. 

12.  Crustulina  altera  Gertsch  &  Archer,  1942 

C.  guttata:  (Emerton),  1882  (nee  Theridion  guttatum  Wider,  1834)

22);  Porter  (Valparaiso,  21,  22;  Ogden  Dunes,  39,  22);  Tippe- 
canoe (Ross  Biological  Reserve,  5) 

Elliott  (21,  22)  listed  Crustulina  guttata  (Wider).  Willis  J.  Gertsch 
considers  our  species  separate  from  the  European  guttata  (Wider),  hence 
the  name  altera.  Kaston  (32),  page  75,  says,  "In  general  appearance  and 
structure  of  the  genitalia  this  species  [C.  altera]  closely  resembles  gut- 
tata (Wider),  with  which,  in  fact,  it  may  be  identical,  although  Dr. 
Gertsch  thinks  not."

Albany,  May  5,  2,  21,  22);  Clark  (Charlestown,  HS,  35) 
Banks  (2)  collected  this  species  at  Wyandotte,  not  in  Wyandotte 
Cave,  as  Elliott  (22)  has  indicated. 

19.  Latrodectus  variolus  Walckenaer,  1837 

Putnam  (Greencastle,  2,  21,  22,  42);  Porter  (Dunes  Acres,  38, 
39,  42;  Ogden  Dunes,  39,  42);  Brown  (Aug.  10,  1967,  May  1, 
1968,  JJF) 

Levi  (35)  synonymized  Latrodectus  variolus  with  L.  7nactans.  Actu- 
ally what  is  now  known  as  L.  variolus  was  included  in  Levi's  records  of 
L.  curacaviensis.  McCrone  and  Levi  (42)  showed  that  L.  variolus  is  a 
valid   species   based   on   coloration  and   ecology.   Therefore   the   records

1,  2,  6,  4,  21;  Mayfield's  Cave,  4,  44,  21,  22);  INDIANA   (49) 

Blatchley  (6)  receives  credit  for  a  Truett's  Cave  record  because  he 
states,  on  page  204,  "This  species  was  also  noted  in  the  first  room  of 
Truett's  Cave— W.S.B." 

The  date  of  the  description  of  this  species  should  be  1897,  not  1896, 
as  Banks  (2,  3)  has  indicated.  Banks  described  Theridion  porteri  in  the 
same  publication  as  the  description  of  Tegenaria  cavicola.  The  reader 
is  referred  to  a  discussion  of  the  date  change  under  Tegenaria  cavicola.

LaPorte  (Smith,  39,  22) 

Elliott  (22)  copied  Lowrie's  record  incorrectly.  The  record  should 
have  been  Theridion  unimaculatum,  not  T.  albomaculatum  as  Elliott  has 
indicated.  T.  albomaculatum  occurs  from  Georgia,  Texas,  and  Florida, 
south  to  Brazil.

Cave,  6,  2,  21,  22);  INDIANA  (49) 
The  Bradford  Cave  record  for  this  species  will  always  remain  du- 
bious.  Emerton    (23)    says,   "A  cocoon   collected   by   Mr.   Packard,   from 
Bradford    Cave,   Ind.,    contains    young,    which    had    passed   their   second 
moult,  probably  of  this  species." 

Packard   (47)   states,  ".  .  .  while  in  the  Bradford  Cave  occurred  a 

Nesticus  thought  by  Mr.  Emerton  to  be  identical  with  Nesticus  Carteri." 

Packard  (48)  does  not  accept  the  Bradford  Cave  record  of  Nesticus 

carteri  Emerton  as  a  valid  one,  for  on  page  83  he  lists,  "Nesticus  carteri 

Emerton,  Amer.  Naturalist,  ix,  May,  1875.  Carter  Caves,  Kentucky."

Chamberlin  and  Ivie  (11)  are  convinced  that  P.  costatus  is  different 
from  the  European  Linyphia  phrygiana.  They  state,  on  page  28,  "This 
common  species  of  the  eastern  United  States  is  distinct  from  the  Euro- 
pean phrygiana,  where  it  has  been  consistently  placed  by  American  au- 
thors.  The  above  name  [P.  costatus  (Hentz)],  therefore,  should  be  used."

ton (Huntington,  Aug.  15,  1967,  TAP) 

Chamberlin  and  Ivie  (11)  say  that  Linyphia  pusilla  Sundevall,  1830 
is  European  and  does  not  occur  in  North  America.  They  consider  their 
Pusillia  pusilla  distinct  from  Pusillia  mandibulata  Emerton,  1882.  Ap- 
parently what  was  formerly  known  as  Linyphia  pusilla  is  now  Pusillia 
mandibulata  in  the  East  and  their  new  Pusillia  bonita  in  the  West.

(49) 

Emerton  (23)  did  not  record  this  species  from  Wyandotte  Cave  as 
Elliott  (22)  has  indicated.  Mclndoo  (44),  on  page  183,  says,  "This  species 
[Linyphia  Weyeri  Emer.]  in  this  cave  [Marengo  Cave]  is  as  abundant  as 
Troglohypha?ites  (  =  Willibaldia)  cavernicola  Keys,  is  in  the  Shawnee 
Cave." 

Elliott  (21)  lists  Mayfield's  Cave  and  Hamer's  Cave  for  this  species. 
Elliott  (22)  credits  the  Mayfield's  Cave  record  to  Banta  and  drops  the 
Hamer's  Cave  record.  Banta  (4)  did  not  collect  this  species  in  Mayfield's 
Cave,  and  the  writer  is  certain  that  a  Hamer's  Cave  collection  never 
existed. 

Elliott  (22)  should  not  have  included  Troglohyphantes  incertus  Emer. 
in  the  list  of  Indiana  spiders.  Emerton  described  this  spider  in  1875  from 
specimens  taken  in  caves  in  Virginia  and  Kentucky.  The  last  paragraph 
of  the  description,  which  is  also  included  in  Packard  (48),  pages  275-276, 
says,  "Fountain  Cave,  Virginia,  among  stalactites,  in  company  with 
Nesticus  ijallidus  (Packard);  also  in  Bat  Cave,  Carter  County,  Kentucky 
(Shaler  and  Packard)."

Entomology  275 

The  writer  is  hesitant  to  include  this  spider  as  a  record  for  Indiana. 
Elliott  (22)  included  this  spider  as  A.  mammouthia  Tellkampf.  Cope  (18) 
listed  specimens  from  Wyandotte  Cave  as  Anthrobia.  He  gave  these 
specimens  no  specific  name,  believing  them  different  from  A.  mam- 
mouthia, which  he  had  listed  from  Mammouth  Cave,  Kentucky.  Cope 
gives  this  account  of  his  collections  in  Wyandotte  Cave:  "Two  species  of 
Arachnidans  were  observed,  one  a  true  spider,  the  other  related  to  the 
"long-legs"  of  the  woods.  A  species  similar  to  the  former  is  found  in  the 
Mammouth  Cave  [A.  mammouthia],  and  others  in  other  caves,  but  in 
every  instance  where  I  have  obtained  them,  they  have  been  lost  by  the 
dissolution  of  their  delicate  tissues  in  the  impure  alcohol." 

Emerton  (23)  had  A.  mammouthia  listed  from  Mammouth,  Proctor's 
and  Diamond  Caves,  all  of  which  occur  in  Kentucky.  Emerton  made  no 
mention  of  collecting  A.  mammouthia  from  Wyandotte  Cave  as  Elliott 
(22)  has  indicated.

reported  this  species  in  his  paper.  Banks  (2)  reported  the  same  species 
from  Porter's  Cave,  putting  it  in  the  genus  Gonglydmm.  Elliott  (22) 
should  have  recorded  Oedothorax  tridentatus  Emer.,  not  bidentatus,  as  he 
has  for  number  126.  Elliott  (21)  recorded  O.  bidentatus  synonymizing 
this  species  with  Gonglydium  tridentatus  Emer.  This  synonymy  is 
incorrect.

Elliott  (22)  states  on  page  312  that  Emerton  (23)  collected  Met  a 
menardi  from  Bradford  and  Wyandotte  Caves.  This  inclusion  is  erroneous. 
Emerton  (23),  page  278,  says,  'Two  species  were  found  only  about  the 
mouths  of  caves.  These  are  Theridion  vulgare  Hentz,  a  spider  found 
all  over  the  country  in  shady  places,  and  a  large  species  of  Meta,  which 
has  been  found  in  similar  situations  in  Massachusetts  and  New  Hamp- 
shire, and  resembles  Epeira  fusca  Blackwall." 

Emerton  did  not  say  near  which  caves  these  spiders  were  found,  nor 
did  he  positively  identify  these  spiders  as  Meta  menardi  (Latrielle),  1804. 

Banta  (4)  did  not  report  Meta  menardi  from  Strong's  Cave,  as

After  a  thorough  examination  of  paratype  material  of  Tetragnatha 
guatemalensis  0.  P.  Cambridge,  1889,  the  writer  is  convinced  that  T. 
banksi  and  T.  guatemalensis  are  not  synonymous,  as  Chickering  (13, 
14),  has  concluded.  The  writer  reviewed  McCook  (41),  Levi  and  Field 
(36),  0.  P.  Cambridge  (8),  F.  P.  Cambridge  (7),  Seeley  (52),  and 
Chickering  (13,  14,  15)  in  reaching  the  above  conclusions.  The  writer 
feels  certain  that  T.  seneca  Seeley  is  a  synonym  of  T.  banksi  McCook, 
1894. 

Both  T.  banksi  and  T.  guatemalensis  occur  in  the  United  States. 
Tetragnatha  guatemalensis  reaches  a  few  southern  states  (as  e.g., 
Chamberlin  and  Ivie,  [10]  and  possibly  McCook's  specimens  from  Flor- 
ida). Tetragnatha  banksi  is  more  northern  in  distribution  (as  e.g., 
Seeley's  collections,  Levi  and  Field's  collections,  the  writer's  collections 
and  McCook's  specimen  from  Wisconsin). 

The  "large  tooth"  on  the  male  chelicera  of  T.  guatemalensis  is  al- 
ways missing  in  males  of  T.  banksi.  Chickering  (13)  says  the  "large 
tooth"  of  T.  guatemalensis  males  is  not  well  developed  and  that  of  T. 


284  Indiana  Academy  of  Science 

banksi  is  a  reduced  condition.  The  writer  has  found  and  D.  J.  Clark 
of  the  British  Museum  reaffirms  that  the  "large  tooth"  is  quite  strong 
in  the  male  of  T.  guatemalensis. 

Since  Tetragnatha  guatemalensis  is  found  in  the  United  States,  a 
series  of  "large  tooth"  reductions  should  be  found  in  males  as  one  travels 
from  south  to  north  if  one  wishes  to  synonymize  this  species  with  T. 
banksi.    The  writer  can  find  no  evidence  of  such  a  cline.

Banks  (2,  3)  lists  the  date  of  his  description  of  Tegenaria  cavicola 
as  1896.  The  date  should  be  1897,  for  the  21st  Annual  Report  of  the

Banks  (2)  and  Elliott  (21,  22)  report  that  Banta  (4)  collected  this 
species  from  Twin  Cave.  Banta  says  nothing  about  a  Twin  Cave  collec- 
tion. Banks  probably  means  Banta's  Lower  Twin  Cave  at  Mitchell, 
which  is  in  Lawrence  County.  Apparently  Banta  had  done  some  collect- 
ing around  Mitchell,  Indiana,  and  did  not  mention  many  of  these  collec-

Wallace  (54)  states,  "Geolycosa  fatifera  (Hentz)  is  obviously  closely 
related  to  missouriensis  (Banks).  Superficially  they  resemble  each  other 
closely,  but  their  genitalia  are  distinct.  It  may  be  that,  when  males  have 
been  taken  from  a  wider  area,  this  species  will  be  found  to  intergrade 
with  missouriensis. ,"

Lake?  (Miller,  53;  Pine,  53;  Clark,  53);  Porter?  (Ind.  Dunes

Comstock  (16,  17)  states,  'The  range  of  this  species  includes  the 
Eastern  and  Middle  States  and  extends  to  the  District  of  Columbia  and 
to  Indiana."  Comstock  apparently  included  the  "Middle  States"  and 
"Indiana"  on  the  basis  of  Shelford's  records.  The  writer  feels  certain 
that  Shelford's  records  were  misidentifications.  Shelford's  G.  pikei  was 
most  likely  G.  wrightii  which  is  indigenous  to  the  dunes  area  and  was 
described  by  Emerton  in  1912,  the  same  year  Shelford  published  his 
study. 

Wallace  (54)  says  that  Geolycosa  pikei  is  "the  sandy-beach-inhabit- 
ing form  of  the  New  England  seaboard."

Although  Emerton  (24)  designated  no  types,  Wallace  (54)  states 
that  the  probable  female  type  was  collected  at  Chicago,  Illinois,  by

The  writer  can  see  no  reason  why  many  have  chosen  to  use 
Walckenaer's  Drassus  vasifer,  rather  than  Hentz's  Herpyllus  ecclesiasti- 
cus.  Hentz  (28)  gives  an  accurate  description  of  the  species,  gives  it  a 
valid  name,  and  tells  of  its  habits.  He  states,  on  page  102,  ".  .  .  ;  and 
a  blackish  one  with  a  white  band  on  the  cephalothorax,  a  band  on  the 
abdomen,  beginning  at  base  and  reaching  the  middle,  and  a  spot  near  the 
apex  white.  This  one  attains  a  great  size  and  is  found  in  houses, 
under  stones,  planks,  the  bark  of  decaying  trees,  etc.  I  call  it 
H.  ecclesiasticus,  .  .  ." 

Elliott  (22)  lists  Nodocion  sp.  for  number  208.  The  specimen  was 
taken  at  Richmond,  Wayne  Co.,  Indiana.  Levi  (34)  described  Nodocion 
melanie  from  Wisconsin.  Elliott's  specimen  may  be  this  species,  but  the 
writer  has  not  had  the  opportunity  to  examine  the  specimen.  Three  other 
species  of  Nodocion  are  found  in  the  West.

Elliott  (20,  21,  22)  to  Zelotes  subterraneus.   Hentz  (28)  probably  had  two

Kaston  (32)  following  Petrunkevitch  (49)  states  that  Attus  rufus  Hentz 
is  unknown  to  modern  araneologists  since  the  descriptions  are  too  meager 
to  place  this  spider  in  a  proper  genus.

Elliott  (21,  22)  synonymized  A.  rufus  with  P.  whitmanii  Peckham,

Appendix  II 
Obscure  Collecting  Localities 

Americus,  Tippecanoe  County — The  collections  were  made  along  the 
Tippecanoe  River,  approximately  one  mile  upstream  from  the  junction  of 
the  Tippecanoe  and  Wabash  Rivers. 

Arlington,  Marshall  County — Banks  (2)  states  that  this  town  was  in 
Marshall  County,  not  the  Arlington  in  Rush  County.  The  writer  cannot 
determine  its  exact  location  in  the  county. 

Buffington,  Lake  County — This  town  was  formerly  called  Edgemoor 
and  was  located  in  section  26  of  Calumet  Township.  It  was  later  taken 
into  Gary. 

Clark,  Lake  County — This  town  was  located  on  the  eastern  edge  of 
North  Township  which  is  now  Hammond. 

Cypress  Swamp,  Knox  County — This  area,  also  known  as  Great 
Cypress  Swamp,  is  approximately  two  miles  northeast  of  the  confluence 
of  the  Wabash  and  White  Rivers. 

Entomological  Research  Area,  Tippecanoe  County — This  collecting 
area  is  part  of  the  Horticultural  Farm  which  lies  approximately  two 
miles  west  of  the  Purdue  Campus  on  Sharon  Chapel  Road. 

Grand  Chain,  Posey  County — This  area  is  approximately  eight  miles 
south  of  New  Harmony  along  the  Wabash  River. 

Hessville,  Lake  County — This  town,  which  was  in  North  Township, 
is  now  part  of  Hammond. 

Liverpool,  Lake  County — This  town  is  located  at  the  western  edge  of 
Hobart  Township. 

Merritt's  Pine  Plantation,  Tippecanoe  County — This  privately-owned 
Christmas  tree  plantation  is  located  approximately  %  mile  east  of  the 
Wildcat  Creek  bridge  on  the  south  side  of  State  Road  25. 

Miller,  Lake  County — This  town  was  located  in  section  6  of  Hobart 
Township  and  is  now  part  of  Gary. 

Mount  Carmel,  Gibson  County — Although  Mount  Carmel  is  actually 
situated  on  the  west  bank  of  the  Wabash  River  (Illinois),  all  collections 
were  made  on  the  east  bank  of  the  river  (Indiana). 

Mount  Vernon,  Posey  County — All  collections  were  made  along  the 
east  bank  of  the  Wabash  River  which  is  approximately  eight  miles  due 
west  of  Mount  Vernon.  The  Mount  Vernon  record  for  Loxosceles  reclusa 
was  taken  in  the  town,  not  along  the  Wabash. 

Otis,  LaPorte  County — This  town  is  in  New  Durham  Township. 

Pine,  Lake  County — This  town  was  situated  along  Lake  Michigan 
and  is  now  the  north  end  of  Clark  Street  in  Gary. 

Ross  Biological  Reserve,  Tippecanoe  County — This  preserved  area 
lies  along  the  Wabash  River  adjacent  to  the  staff  recreation  area,  "The 
Hills."  These  areas  are  located  approximately  ten  miles  southwest  of 
West  Lafayette.

Gypsum  Resources  of  the  Midwestern  United  States.  John  H.  Cleveland 
and  Carol  F.  Tiefel,  Indiana  State  University. — Gypsum  (CaS04#2H20) 
as  an  economic  mineral  is  primarily  utilized  in  the  construction  industry 
for  prefabricated  plasterboard.  Although  the  value  of  raw  gypsum  is  less 
than  $5.00  per  ton,  its  production  is  economically  significant  because  the 
fabricated  products  are  normally  produced  at  plants  adjacent  to  the  mine 
and  constitute  a  ten-fold  increase  in  value.  Commercial  gypsum  deposits 
must  have  large  reserves,  minable  thickness,  moderate  depth,  and  a  loca- 
tion near  major  population  centers.  Present  regional  production  is  con- 
fined to  six  districts  in  four  states  (Indiana,  Iowa,  Michigan,  and  Ohio) 
and  is  obtained  from  rocks  of  four  different  geologic  periods  (Silurian, 
Devonian,  Mississippian,  and  Permian?).  All  of  the  region's  known 
commercial  gypsum  deposits  are  sedimentary  in  origin  and  genetically 
related  to  evaporite  basins,  but  are  the  final  product  of  recent  rehydration 
of  anhydrite  at  shallow  depths.  Contrary  to  prevailing  mining  industry 
trends,  quarry  operations  are  being  replaced  by  underground  mines  with 
future  development  likely  in  the  form  of  multipurpose  underground  mines 
in  close  proximity  to  major  populations.  Recent  published  investigations 
of  newly  recognized  gypsum  reserves  at  LaPorte,  Indiana  and  Albia, 
Iowa  suggest  they  may  fit  this  pattern. 

A  Significant  Exposure  of  Pleistocene  Drift  in  South-Central  Indiana.* 

Allan  F.  Schneider,  Indiana  Geological  Survey. — Unconsolidated 
deposits  of  the  Pleistocene  Series  are  exposed  in  a  railroad  cut  at  the 
glacial  boundary  in  northwestern  Brown  County.  The  section  is  signifi- 
cant because  it  exhibits  a  more  complete  sequence  of  Pleistocene  sedi- 
ments than  other  exposures  in  the  area  and  because  it  corroborates  W.  J. 
Wayne's  conclusion  that  in  northwestern  Brown  County  glacier  ice  of  the 
Kansan  Age  advanced  somewhat  farther  than  ice  of  the  Illionian  Age. 

Siltstone  of  the  Borden  Group  (Mississippian  System)  at  the  base  of 
the  cut  is  overlain  unconformably  by  3%  feet  of  unoxidized  and  oxidized 
till  interpreted  as  Kansan  in  age.  The  till  is  overlain  by  about  30  feet  of 
fine  gravel  and  pebbly  sand,  much  of  which  is  strongly  oxidized.  In  its 
upper  part  this  deposit  is  altered  to  a  sticky  reddish-brown  sandy  mate- 
rial that  clearly  represents  a  significant  period  of  weathering.  The 
gravel  and  sand  is  regarded  as  Illinoian  outwash,  and  the  weathering  pro- 
file is  interpreted  as  having  formed  during  the  interglacial  Sangamonian 
Age. 

The  section  is  capped  by  about  6  feet  of  silt,  which  is  probably  of 
eolian    rather   than    lacustrine    origin.     In    its    lower    part    the    loess    is

clayey  and  similar  in  color  to  the  underlying  weathered  outwash  but 
grades  upward  into  more  typical  noncalcareous  loess.  The  reddish-brown 
silt  is  tentatively  considered  to  be  Illinoian  and  Sangamonian  and  the 
upper  part  Wisconsinan  in  age. 

Unconsolidated  Deposits  on  the  Mitchell  Plain  of  Indiana. i  Richard  L. 
Powell,  Indiana  Geologicol  Survey. — The  Mitchell  Plain  of  south-central 
Indiana  is  a  limestone  plateau  partly  mantled  with  unconsolidated  ma- 
terials that  consist  mostly  of  loess,  gravels,  and  clays  that  attain  60  feet 
in  thickness.  Most  of  the  material  is  clay  in  layers  of  red,  brown,  or 
olive  and  yellow.  In  places  the  clay  overlies  coarser  sedimnts.  A  persis- 
tent bed  of  cherty  gravel,  which  in  places  contains  a  few  allochthonous 
geode  fragments  and  lenses  of  sandstone  pebbles,  overlies  the  clays 
where  they  have  not  been  eroded.  The  cherty  gravel  bed  lies  at  an  alti- 
tude similar  to  that  of  some  Lafayette  gravel  deposits  along  entrenched 
meandering  drainage  routes.  The  present  entrenched  drainage  pattern 
evolved  from  drainage  on  a  westward-sloping  erosion  and  deposition 
surface  that  had  developed  on  the  Mitchell  Plain  and  the  Norman  Upland 
by  the  time  that  the  cherty  gravel  bed  was  deposited.  Entrenchment  of 
the  major  streams  during  late  Tertiary  or  early  Pleistocene  time  and 
during  mid-Pleistocene  time  accelerated  cavern  and  sinkhole  develop- 
ment on  the  Mitchell  Plain  and  was  accompanied  by  erosion  of  the  clays 
and  gravels  and  partial  redeposition  in  sinkholes  and  caverns.  Loess  of 
late  Pleistocene  age  blanketed  the  region  prior  to  recent  erosion.

Analysis  of  Surficial  Landform  Properties:     The   Regionalization 
of  Indiana  into  Units  of  Morphometric  Similarity1 

Laurence  A.  Lewis,  Temple  University 

Abstract 

This  study  offers  a  more  rigorous  alternative  to  the  traditional  reli- 
ance on  qualitative  data  and  the  subjective  approach  in  the  regionalization 
of  geomorphic  units.  Using  analytical  data  and  techniques,  regional  geo- 
morphic  units  are  developed  for  Indiana.  The  results  of  a  principal  com- 
ponets  analysis  and  a  cluster  analysis  indicate  that  Indiana  can  be  region- 
alized using  three  primary  morphometric  components:  a  vertical  componet, 
an  areal  magnitude  factor  and  a  stream  network  development  factor.  In 
addition,  a  lacustrine  factor  is  found  to  be  of  secondary  importance  within 
Indiana. 

The  areal  patterns  of  these  morphomeric  components  indicate  that  the 
previous  physiographic  or  regional  geomorphic  units  developed  for  Indiana 
fail  in  delimiting  the  State  into  regions  of  form  similarity.  The  previous 
investigations,  by  concentrating  on  geologic  structure  and/or  process  in- 
stead of  the  actual  topographic  expression,  most  likely  account  for  this 
failure. 

Introduction 

In  previous  physiographic  or  regional  geomorphic  studies,  the  cri- 
teria utilized  in  delimiting  "natural"  regions  have  been  highly  subjective 
and  somewhat  inconsistent.  Traditionally,  regional  geomorphic  studies 
have  relied  heavily  on  qualitative  descriptions  of  bedrock  structure, 
general  landform  characteristics,  geologic  history  and/or  climatic  charac- 
teristics as  the  basis  for  forming  different  regions.  Likewise,  criteria 
which  are  considered  crucial  for  the  location  of  regional  boundaries  vary 
from  area  to  area  in  the  regional  studies  of  Fenneman  (1),  Thornbury 
(4)  and  Hunt  (3).  Hammond  has  reported  on  the  need  to  use  the  iden- 
tical criteria  throughout  a  single  study  and  has  attempted  to  minimize 
subjective  data  by  substituting  measurable  landform  characteristics  as 
the  standard  for  delimiting  landform  regions  (2).  In  his  regionalization 
of  the  United  States,  Hammond  utilized  four  variables:  slope  inclina- 
tion, vertical  dimension,  general  profile  character  and  some  aspects  of 
surface  material.  While  Hammond's  work  represented  a  start,  it  did 
not  satisfactorily  eliminate  the  problem  of  subjective  data  or  completely 
meet  the  needs  of  geomorphology.  First,  only  two  of  the  variables  used 
could  be  measured — slope  inclination  and  vertical  dimension;  the  two 
remaining  variables  are  subjective  in  nature.  Second,  the  purpose  of 
the  study  was  to  develop  regions  that  would  indicate  areas  of  similar 
land-use.  From  a  geomorphic  point  of  view,  this  is  not  a  particularly 
useful  purpose.  Clearly,  the  need  still  exists  to  use  analytical  criteria  in 
the  construction  of  regions  that  meet  the  needs  of  geomorphology. 

A  landform  assemblage  results  from  the  interaction  of  three  basic 
factors:   process,  time  and  geologic  structure.  Only  the  result  of  these

three  factors,  namely  topographic  expression,  should  be  the  prime  con- 
cern when  delimiting  geomorphic  regions.  Therefore,  the  criteria  used  in 
the  formation  of  geomorphic  regions  should  be  limited  to  surficial  form 
elements.  If  one  of  the  primary  factors  strongly  affects  a  given  area, 
the  morphometric  properties  of  the  surface  will  reflect  the  causal  in- 
fluence. 

This  study  is  the  initial  report  of  an  attempt  to  delimit  geomorphic 
regions  solely  using  quantitatively  measurable  data.  By  limiting  the 
criteria  to  variables  that  can  be  measured,  analytical  techniques  can  be 
used  to  develop  regions  that  will  minimize  subjectivity  and  permit  re- 
liable comparisons  between  features  found  in  different  areas.  These  re- 
gions, where  the  form  elements  are  evaluated  numerically,  in  turn  may 
be  used  to  evaluate  the  controls  of  the  environment  in  individual  process 
oriented  geomorphic  studies.  Specifically,  this  study  regionalizes  the 
State   of  Indiana   into   areas   of  morphometric   similarity. 

Variables 

Thirteen  variables  (Table  1),  all  of  which  have  been  utilized  in  previ- 
ous geomorphic  studies,  form  the  basis  for  the  regionalization  of  Indiana 
into  similar  morphometric  areas.  This  set  of  variables  measures  the  ma- 
jor surficial  properties  of  landforms.  The  data  for  these  variables  are 
obtained  from  U.S.G.S.  topographic  maps. 

Within  a  general  systems  framework,  the  stream  basin  can  be  con- 
sidered the  basic  or  prevalent  geomorphic  system;  furthermore,  within 
the  United  States,  all  land  areas  are  affected  by  streams  and  their  re- 
lated processes.  For  these  reasons,  stream  basins  are  chosen  as  the  basic 
unit  of  measurement  in  this  study.  With  the  exception  of  one  variable 
(percent  of  water),  all  of  the  variables  in  this  study  are  calculated  from 
4th  order  stream  basins. 

A  random  sample  of  sixty  quadrangles  was  drawn  from  all  the 
U.S.G.S.  topographic  maps  (scale  1:24,000)  that  cover  Indiana.  The 
sample  size  insured  ample  areal  coverage  of  the  whole  State  (Figure  1). 
On  each  quadrangle  drawn  from  the  sample,  the  center  of  the  map 
served  as  the  base  from  which  the  nearest  fourth  order  basin  was  lo- 
cated. As  an  indication  of  basin  size,  a  fourth  order  basin  might  extend 
over  six  quadrangles.  For  the  variable,  percentage  of  water,  only  the 
original  quadrangle  drawn  in  the  sample  was  utilized. 

Analysis 

The  multiplicity  of  variables  used  in  this  study  requires  simplifica- 
tion in  order  to  remove  redundancy  among  the  variables  and  to  discover 
the  contrasting  morphometric  elements.  This  can  be  achieved  by  utiliz- 
ing the  technique  of  principal  components  analysis.  The  purpose  of  using 
this  technique  is  to  investigate  how  much  of  the  total  variance  within 
the  sixty  stream  basins,  exhibited  in  the  thirteen  variables,  can  be  ac- 
counted for  by  a  smaller  number  of  new  "principal  components."  These

principal  components  will  form  the  basis  for  regionalizing  Indiana  into 
morphometric  areas. 

Transformation  of  ten  of  the  variables  into  their  logarithmic  equiva- 
lent was  required  to  satisfy  the  assumptions  of  normality  and  linearity 
for  the  data  (Table  2).  After  the  transformations,  the  correlation  matrix 
was  subjected  to  a  principal  axis  solution  in  which  five  of  the  eigen- 
vectors (those  having  values  greater  than  1.00)  were  rotated  to  a  normal 
varimax  position.  These  five  orthogonal  factors  account  for  approxi- 
mately eighty-three  percent  of  the  total  variance  in  the  original  data 
matrix  (Table  3).  From  examination  of  the  varimax  solution,  these  five 
factors  designated  the  vertical  or  ''steepness"  factor,  the  horizontal  or 
areal  magnitude  factor,  level  of  stream  network  development,  basin 
shape  and  the  lacustrine  factor  respectively. 

With  the  isolation  of  the  five  principal  components,  the  next  step  in 
the  regionalization  is  to  aggregate  the  sixty  individual  factor  scores  into 
groups  of  similarity.  The  degree  of  similarity  among  the  factor  scores 
is  determined  by  the  distance  between  each  observation  in  factor  space. 
Close  points  are  considered  similar  to  each  other;  distant  points  or  ag- 
gregates of  points  distant  from  each  other  are  considered  dissimilar. 

The  Vertical  Component.  The  vertical  component,  which  accounts 
for  36.3  percent  of  the  total  variance  (Table  3),  is  identified  primarily 
with  relief,  the  slope  of  the  land,  and  stream  gradient  (Table  2).  Since 
this  component  accounts  for  the  largest  proportion  of  the  total  variance, 
it  appears  to  be  the  most  important  surficial  element  of  variation  within

Indiana.  Inspection  of  the  plot  of  the  factor  scores  for  the  first  com- 
ponent indicated  that  the  vertical  factor  aggregates  into  three  basic 
groups: 

Figure  1  illustrates  the  areal  expression  of  the  vertical  component  for 
the  three  factor  groupings. 

The  general  pattern  of  vertical  land  expression  increases  toward  the 
south.  The  three  regions,  as  delimited  on  the  map,  show  no  simple  correla- 
tion to  the  previous  more  genetic  oriented  regions.  While  it  is  true  that 
the  area  of  maximum  vertical  expression  is  primarily  located  in  areas  not 
glaciated  during  the  Wisconsin  Period,  it  is  not  limited  to  the  non- 
glaciated  portion  of  the  State.  Likewise,  physiographic  regions  such  as 
the  Crawford  upland  and  Mitchell  plain  appear  not  to  be  valid  divisions 
in  regard  to  morphometric  elements.  This  is  substantiated  further  by  the 
second  and  third  components. 

Areal  Magnitude  Factor.  The  highest  factor  loadings  on  the  second 
component  are  essentially  measures  of  stream  basin  extensiveness.  Simi- 
lar to  the  first  component,  the  plot  of  the  factor  scores  for  the  magnitude 
factor  indicate  three  grouping: 

group  one  — 1.165  to  — 0.439 

group  two  —0.539  to  0.384 

group    three  0.416  to  1.205 

The  areal  expression  of  these  three  factor  groupings  are  delimited  on 
Figure  2.  As  with  the  first  component,  no  strong  correlations  between 
the  previous  physiographic  units  of  glaciated  and  non-glaciated  areas 
and  various  glacial  phenomena  are  reflected  by  this   component. 

Stream  Network  Development  Factor.  This  component  represents 
the  last  major  dimension  contributing  to  morphometric  variation  within 
the  State  (Table  3).  The  remaining  two  components  account  for  only 
16  percent  of  the  total  variability.  The  plot  of  the  factor  scores  for  this 
component  indicates  the  following  groupings: 

group   one  —1.870   to   —0.796 

group  two  —0.695  to  0.622 

group   three  0.717  to  2.240 

The  areal  expression  of  these  groupings  is  given  on  Figure  3.  The  areas 
of  maximum  development  follow  the  major  stream  systems  within  the 
State  regardless  of  the  underlying  materials.  This  would  seem  to  indicate 
that  if  physiographic  units  use  genetic  criteria  as  the  basis  for  division, 
more  emphasis  should  be  placed  on  current-day  processes  than  past 
phenomena. 

The  Shape  Factor.  It  is  suggested  that  the  shape  component,  which 
is  heavily  weighted  only  by  one  variable  (Table  2),  be  disregarded  as  a 
criterion  for  regionalization.  First,  inspection  of  the  factor  score  plot 
showed  no  apparent  groupings.  The  values  appeared  as  a  continuum. 
Second,  inspection  of  the  areal  expression  of  the  absolute  values  of  the 
factor  scores  indicated  a  random  pattern  throughout  the  State.  The  be- 
havior of  this  component  could  be  interpreted  as  indicating  that  stream

basin  shape  is  purely  a  result  of  random  processes.  However,  it  probably 
reflects  the  difficulty  of  developing  any  quantitative  measure  of  shape 
without  the  use  of  vectors. 

The  Lacustrine  Factor.  With  the  fifth  component  accounting  for 
only  7.9  percent  of  the  total  variability,  it  is  considered  to  be  of  second- 
ary importance  when  delimiting  regions  within  Indiana.  The  plot  of  the 
factor  scores  indicated  a  dichotomous  arrangement : 

group  one  less  than   0.514 

group  two  greater  than  1.080 

Figure  4  shows  that  the  land  areas  in  the  immediate  vicinity  of  Lake 
Michigan  and  the  northeastern  portion  of  Indiana  are  different  from 
the  remaining  portion  with  regard  to  this  component. 

Conclusions 

This  study  offers  a  more  rigorous  alternative  to  the  traditional  re- 
liance on  qualitative  data  and  the  subjective  approach  in  the  regional- 
ization  of  geomorphic  units.  Using  analytical  data  and  techniques,  re- 
gional geomorphic  units  are  developed  for  Indiana.  Since  the  individual 
form  elements  within  the  regions  can  be  evaluated  numerically,  reliable 
comparisons  between  different  areas  are  possible  in  contrast  to  the  sub- 
jective regional  comparisons  that  must  result  when  using  the  traditional 
approach. 

This  study  establishes  that  three  basic  factors  determine  the  vari- 
ance of  morphometric  properties  throughout  Indiana;  namely,  the  verti- 
cal expression  of  the  land,  the  horizontal  expression  of  the  land  and  the 
development  of  stream  networks.  While  this  study  successfully  isolates 
areas  having  similar  morphometric  properties,  no  attempt  is  made  to 
combine  the  three  primary  components  into  a  composite  regionalization. 
The  need  still  exists  to  investigate  other  areas  in  order  to  develop  a 
better  understanding  of  the  exact  values  of  the  factor  scores  and  to  deter- 
mine if  the  limits  of  the  factor  scores  used  in  this  study  can  be  applied 
universally  before  a  composite  classification  is  developed. 

From  the  inspection  of  the  areal  pattern  of  the  three  components,  it 
appears  that  previous  physiographic  studies  do  not  delimit  Indiana  into 
regions  of  form  similarity.  Most  likely,  this  results  from  their  over 
emphasis  on  geologic  structure  and  geologic  history  as  the  basic  criteria 
for  regionalization.  By  concentrating  on  the  actual  topographic  expres- 
sion and  using  analytical  techniques  offered  in  this  study,  the  undue  in- 
fluence of  a  single  contributing  factor,  such  as  geologic  structure,  is 
prevented.  If  a  purpose  of  regional  geomorphic  studies  is  to  complement 
process-oriented  geomorphic  studies,  regionalization  using  analytical  pro- 
cedures will  be  more  fruitful  than  the  traditional  approach.

Earth  Science  Teaching  in  the  Secondary  Schools  of  Indiana 

Rogek  F.  Boneham,  Indiana  University  at  Kokomo 

An  earth  science  course  in  the  secondary  schools  of  Indiana  is  a 
relatively  new  innovation.  The  purpose  of  this  study  was  to  provide  in- 
formation about  earth  science  teachers  and  to  learn  what  are  some  of 
the  problems  they  are  faced  with  in  conducting  this  new  course. 

This  secondary  school  instruction  in  earth  science  will  have  a  direct 
bearing  on  the  enrollments  in  those  college  departments  which  deal  with 
some  phase  of  earth  science.  Some  students  with  an  inclination  toward 
a  scientific  career  may  become  interested  in  earth  science  after  taking 
such  a  course  and  decide  to  major  in  one  of  its  numerous  branches  in 
college. 

The  responsibility  for  maintaining  viable  earth  science  courses  in 
secondary  schools  rests,  of  course,  with  the  teachers  and  supervisors  of 
the  respective  school  systems.  However,  we  teachers  at  the  college  level 
cannot  divorce  ourselves  completly  from  the  secondary  school  system. 
Many  of  its  students  ultimately  become  our  students.  If  we  can  help 
them  become  better  prepared  for  college  study  then  it  is  beneficial  to 
both  the  students  and  ourselves.  The  Earth  Science  Curriculum  Project 
was  just  such  an  acknowledgment  of  our  responsibility  toward  better 
secondary  school  education. 

The  Indiana  University  School  of  Science  has  a  list  of  secondary 
school  earth  science  teachers  in  Indiana.  A  three-page  questionnaire  was 
sent  to  the  165  teachers  on  this  list.  Seventy-three  questionnaires  were 
returned,  sixty-eight  from  earth  science  teachers  and  five  from  teachers 
who  did  not  teach  earth  science.  It  is  likely  that  a  number  of  teachers 
who  did  not  return  the  questionnaire  do  not  teach  earth  science. 

The  following  list  contains  the  counties  in  which  there  are  earth 
science  teachers: 

County  with  9  teachers:   Marion 

Counties  with  6  teachers :  Allen,  Lake 

County  with  5  teachers:   Bartholomew 

County  with  4  teachers :   Delaware 

County  with  3  teachers:  Porter 

Counties  with  2  teachers:  Fulton,  Hamilton,  Howard,  Jackson,  Madison, 
Montgomery,  Tipton,  Vigo 

Counties  with  1  teacher:  Boone,  DeKalb,  Dubois,  Elkhart,  Harrison,  Hen- 
dricks, Henry,  Jefferson,  Knox,  Kosciusko,  LaPorte,  Noble,  Orange, 
Parke,  Posey,  Randolph,   Spencer,  Sullivan,  Vermillion,  Wayne 

A  few  of  the  respondents  taught  seventh  or  eighth  grade  courses  in 
earth  science.  These  classes  were  not  included  in  this  survey,  since  I  was 
concerned  with  senior  high  school.  However,  the  teachers  were  included 
with  the  senior  high  school  teachers  of  this  survey.

to  each  phase  of  earth  science  in  the  two-semester  courses  were: 

Introduction  2  weeks 

Geology  16  weeks 

Astronomy  6  weeks 

Meteorology  6  weeks 

Oceanography  4  weeks 

In  the  senior  high  school  for  1967-68,  there  were  3924  students  in  142 
sections  for  a  mean  of  27  students  per  section.  The  approximate  enroll- 
ment for  1966-67  was  3566  students.  This  shows  an  increase  of  approxi- 
mately 350  students  during  1967-68  over  1966-67  or  approximately  13 
sections  of  27  students. 

Earth  science  teaching  in  Indiana  really  began  in  the  last  decade  as 
the  following  list  shows:

Earth  science  is  taught  in  various  schools  from  grade  7  through 
grade  12.  The  schools  were  divided  into  32  teaching  the  course  to  a 
single  grade  and  29  teaching  multiple  grade  sections.  The  majority 
taught  earth  science  in  grades  8-10.  Two  schools  offered  it  to  seventh 
graders  and  21  offered  it  to  grades  11  and  12. 

The  teachers  were  requested  to  supply  information  about  the  aca- 
demic ability  of  their  students.  The  following  list  is  the  median 
percentages  of  earth  science  students: 

College  caliber  30% 

Terminal  high  school  60% 

Potential  drop-outs  10% 

There  was  approximately  a  3:1  favorable  response  to  the  question, 
"Should  the  earth  science  curriculum  be  expanded?"  Those  who  favored 
curriculum  expansion  usually  listed  more  than  one  of  the  following: 
more  laboratory  equipment  (34  teaechers);  more  laboratory  space  (24 
teachers);  more  library  volumes  (20  teachers);  more  teachers  (6  teach- 
ers). 

The  greatest  problems  of  earth  science  teachers  were  mainly:  low 
ability  of  students  (21  teachers);  lack  of  equipment  (19  teachers);  lack 
of  background  courses  of  respondent  (16  teachers);  lack  of  space  (12 
teachers);  lack  of  library  volumes  (10  teachers);  lack  of  student  interest 
(9  teachers);  lack  of  administration  interest   (4  teachers). 

Approximately  30%  of  the  teachers  used  the  text  prepared  under 
the  supervision  of  the  Earth  Science  Curriculum  Project.  In  view  of  the 
fact  that  the  text  has  been  available  for  a  short  period  of  time,  it  is 
being  used  by  a  large  number  of  students  in  Indiana. 


Geology  and  Geography  331 

The  two  training  areas  which  the  teachers  found  most  beneficial  to 
their  teaching  were:  courses  attended  on  a  degree  program  and  N.S.F. 
Summer  Institutes.  To  a  lesser  extent  were:  in-service-training  and 
field  work. 

Slightly  more  than  half  of  the  teachers  had  never  attended  an  N.S.F. 
Summer  Institute.  The  great  majority  of  those  who  had  attended  an 
institute  replied  that  they  had  attended  either  one  or  two. 

In  nearly  every  case,  those  who  took  an  N.S.F.  Summer  Institute 
course  in  earth  science  listed  the  Institute  as  their  most  helpful  training 
for  teaching  earth  science. 

The  median  number  of  years  as  a  teacher  listed  by  the  respondents 
was  eight.  The  median  number  of  years  as  an  earth  science  teacher  was 
two.  This  tends  to  indicate  that  the  majority  of  the  earth  science  teachers 
were  not  originally  trained  as  such.  This  point  is  further  proven  later 
in  the  report. 

Approximately  65%  of  the  teachers  had  a  master's  degree.  Those 
with  a  bachelor's  degree  only  had  a  median  of  6-10  hours  beyond  the 
bachelor's  degree.  Those  with  a  master's  degree  had  a  median  of  20+ 
hours  beyond  the  master's  degree. 

The  science  background  of  the  teachers  was  examined.  The  following 
list  gives  the  particular  science  and  the  median  number  of  semester  hours 
credits  of  the  teachers.  This  question  was  arranged  so  that  each 
respondent  could  check  0  hours,  1-9  hours,  10-20  hours,  or  20+  hours.

The  courses  which  the  majority  of  teachers  thought  would  be  most 
beneficial  to  their  teaching  were:  Oceanography  (76%),  Astronomy 
(61%),  Geology  (60%),  and  Meteorology  (38%).  Judging  from  the 
median  semester  hours  of  the  teachers'  background,  it  is  obvious  that 
they  recognize  their  definciencies.  What  is  surprising  though  is  that  so 
few  of  them  felt  a  course  in  Meteorology  would  be  beneficial  since  more 
than  50%  had  never  had  such  a  course. 

Approximately  10%  of  the  teachers  listed  earth  science  or  geology 
as  their  major  for  the  bachelor's  degree,  while  approximately  40%  listed 
biology  as  their  undergraduate  major.  The  remaining  teachers  mainly 
listed  various  fields  of  the  natural  or  biological  sciences  as  their 
undergraduate  major. 

Those  teachers  with  a  master's  degree  mainly  listed  the  following 
majors:  education  (35%),  earth  science  (25%),  and  biology  (15%). 
Their  graduate  degree  minors  were  mainly  education  (40%)  and  biology 
(25%).

Summary 

The  typical  earth  science  teacher  in  Indiana  has  the  following  char- 
acteristics. He — the  large  majority  are  men — has  a  master's  degree  in 
education  or  earth  science  and  a  bachelor's  degree  in  biology.  He  has 
more  than  twenty  hours  of  course  work  beyond  the  master's  degree, 
which  means  that  he  has  probably  spent  a  number  of  his  summers  in 
school  since  he  has  only  been  teaching  for  eight  years. 

He  has  taught  earth  science  for  the  last  two  years,  so  he  must  have 
taught  another  science,  probably  biology,  general  science,  or  possibly 
chemistry  during  most  of  his  career. 

There  is  a  50%  likelihood  that  he  initiated  the  earth  science  course 
at  the  school  in  which  he  now  teaches.  The  school  is  located  in  an  urban 
area  and  his  students  are  in  the  ninth  or  tenth  grade.  His  pupils  are  in 
the  upper  half  of  their  class  and  a  substantial  number  will  continue  their 
education  after  high  school  graduation. 

There  is  a  50%  likelihood  that  he  attended  at  least  one  N.S.F.  Sum- 
mer Institute  in  earth  science.  If  he  did  attend  such  an  institute  he  feels 
this  was  his  best  training  for  instructing  his  earth  science  classes. 

He  wishes  to  expand  the  earth  science  course  at  his  school  with  the 
addition  of  more  laboratory  equipment.  He  would  also  like  to  take 
additional  courses  in  oceanography,  astronomy,  and  geology  in  order 
to  improve  his  teaching  ability. 

This  study  illustrates  that  earth  science  teachers  in  Indiana  generally 
did  not  major  in  earth  science  at  college.  However,  there  is  a  sizeable 
minority,  nearly  20%,  who  do  have  a  master's  degree  in  earth  science. 
Those  teachers  whose  major  field  was  other  than  earth  science  have  been 
greatly  helped  by  having  attended  an  N.S.F.  Summer  Institute  in  earth 
science. 

Earth  science  teaching  in  Indiana  has  really  come  about  within  the 
last  ten  years  and  as  the  number  of  pupils  continue  to  expand,  there  is 
little  doubt  that  their  instructors  will  become  better  qualified  to  teach 
the  subject. 


Stratigraphy   and   Correlation  of  Middle  Devonian   Strata   in  the 
Logansport   Sag,   North-central   Indiana 

R.  William  Orr,  Ball  State  University 

Abstract 

The  name  Traverse  Formation  of  northern  Indiana  and  the  Michigan  Basin 
is  extended  into  the  Logansport  Sag  to  include  approximately  25  feet  of  strata 
previously  separated  into  Miami  Bend  Formation,  Logansport  Limsetone,  and 
Little  Rock  Creek  Limestone.  Traverse  rocks  of  the  Sag  and  those  of  the  Michi- 
gan Basin  of  equivalent  late  Middle  Devonian  age  display  similar  lithologies, 
have  similar  depositional  histories,  and  contain  nearly  identical  conodont 
faunas.  The  Traverse  rocks  of  the  Sag  lie  within  two  Middle  Devonian 
conodont  zones  high  in  the  Givetian  Stage  and  correlate  with  strata  in 
New  York  ranging  from  the  Levanna  Shale  Member  of  the  Skaneateles 
Shale  (Hamilton  Group)  through  the  Tully  Formation.  The  lower  zone 
comprises  the  body  of  strata  containing  Icriodus  latericrescens  latericrescens 
below  the  lowest  position  of  Polygnathus  varcus;  the  upper  zone  is  the 
P.  varcus  Zone. 

Introduction 

Upper  Silurian  and  Devonian  rocks  are  exposed  in  the  valley  of  the 
Wabash  River  between  Delphi,  Carroll  County,  and  Lewisburg,  Cass 
County,  Indiana  (Fig.  1).  The  outcrop  area  is  situated  near  the  crest  of 
the  northwest  extension  of  the  Cincinnati  Arch  in  the  structural  depres- 
sion that  Cumings  and  Shrock   (10)   named  the  Logansport  Sag. 

Approximately  25  feet  of  Middle  Devonian  carbonate  rocks  lie 
between  Silurian  strata  and  the  New  Albany  Shale  (Upper  Devonian). 
Although  the  Middle  Devonian  part  of  the  section  is  quite  thin  and 
exposures  are  relatively  few,  several  units  assigned  the  rank  of  forma- 
tion have  been  proposed  for  rocks  that  crop  out  in  the  Sag.  These  are 
Miami  Bend  Formation  (6),  Logansport  Limestone  (7),  and  Little  Rock 
Creek  Limestone  (5).  These  three  units  nowhere  are  known  to  be  present 
in  a  single  outcrop,  and  their  lateral  and  vertical  relationships  as  a 
result  are  unclear.  With  few  exceptions,  among  them  the  work  of  Cooper 
and  associates  and  that  of  Campbell  (3),  these  names  rarely  have  been 
used.  They  have  not  been  adopted  for  use  by  the  Indiana  Geological 
Survey. 

Middle  Devonian  rocks  of  the  Logansport  Sag  lithologically  more 
closely  resemble  equivalent  rocks  of  the  Michigan  Basin  than  those  of  the 
Illinois  Basin.  As  pointed  out  by  Pinsak  and  Shaver  (15),  rocks  equiva- 
lent to  part  of  the  Traverse  Group  of  Michigan  are  recognized  as  far 
south  as  Carroll,  Cass,  Howard,  and  Miami  Counties,  Indiana.  During 
Middle  Devonian  time  basin  type  sedimentation  was  taking  place  on 
the  northeast  side  of  the  Cincinnati  Arch  and  a  southward-thinning  wedge 
of  sediments  was  deposited  in  northern  Indiana  (15).  The  Miami  Bend, 
Logansport,  and  Little  Rock  Creek  represent  the  southern  extension  of 
this  wedge  into  the  Logansport  Sag. 

Field  work  was  conducted  during  the  summer  of  1967  when  the 
writer   was    associated    with    the    Indiana    Geological    Survey.     Charles

A.  Pollock,  Department  of  Geology,  Indiana  University,  accompanied  the 
writer  in  the  field  and  assisted  in  the  collecting  of  samples.  Charles 
Pollock,  Carl  B.  Rexroad  and  William  J.  Wayne  (both  of  the  Indiana 
Geological  Survey),  and  Robert  S.  Nicoll,  Department  of  Geology,  The 
University  of  Iowa,  discussed  the  stratigraphy  of  the  area  on  several 
occasions.  Carl  Rexroad  and  Robert  Nicoll  critically  read  the  manuscript. 


Development  of  Stratigraphic  Nomenclature 

Middle  Devonian  rocks  of  the  Logansport  area  have  been  studied  by 
numerous  geologists  for  nearly  100  years.  Collett  (4)  made  a  brief 
survey  of  Silurian  and  Devonian  rocks  in  Carroll  and  Cass  Counties 
among  others  in  1872.  He  recognized  two  divisions  of  the  Devonian  part 
of  the  section,  a  lower  limestone  unit  (unnamed  by  Collett)  20  to  22  feet 
thick  and  an  upper  black  shale  unit  60  feet  thick  (Fig.  2).  Collett  used 
the  name  "Louisville-Delphi  black  slate"  for  the  latter  unit  in  two  col-

umnar  sections.  As  pointed  out  by  Wilmarth  (23),  the  "Louisville-Delphi 
black  slate"  probably  was  named  for  its  surface  distribution  from  Louis- 
ville, Kentucky,  to  Delphi,  Carroll  County,  Indiana.  Brown  (2)  used  the 
name  "Delphi  black  slate"  to  designate  the  same  unit  in  Marion  County, 
Indiana.  Both  names  have  since  been  replaced  in  common  usage  by  the 
older  and  more  widely  accepted  name  New  Albany   Shale    (1). 

Kindle  (13)  distinguished  two  divisions  of  Devonian  carbonate  rocks 
in  the  Wabash  Valley  near  Logansport,  a  lower,  gray,  crystalline,  thin- 
to  thick-bedded  limestone  and  an  upper  limestone  that  varies  from  bluish 
drab  and  conchoidally  fracturing  to  dark  colored  and  arenaceous.  He 
correlated  the  lower  unit  with  the  Jeffersonville  Limestone  (an  untenable 
correlation  on  the  basis  of  conodont  succession)  of  southern  Indiana  and 
applied  the  southern  Indiana  term  Sellersburg  beds  (12)  to  the  upper 
limestone  and  noted  its  Hamilton  fauna.  He  provisionally  assigned  to  the 
Silurian  the  stromatoporoid-bearing  limestone  that  he  observed  to  be 
10  to  13  feet  thick  below  the  lower  unit  (Fig.  2). 

Cooper  and  Warthin  (7)  proposed  the  name  Logansport  Limestone 
for  "light-colored  granular  limestone"  in  which  "corals  and  other  fossils 
are  abundant  particularly  in  the  upper  6  feet"  for  Middle  Devonian  lime- 
stone that  rests  on  the  Silurian  at  many  places  in  the  Logansport  area. 
They  designated  as  type  section  the  exposure  at  Pipe  Creek  Falls  (Local- 
ity 7)  where  Middle  Devonian  rocks  consist  of  a  lower,  gray,  fine-grained, 
stromatoporoid-bearing   unit    (assigned   to    the    Silurian   by   Kindle   but 


336  Indiana  Academy  of  Science 

more  properly  Middle  Devonian)  and  an  upper,  pink,  granular,  abundantly 
fossiliferous  unit  (=  the  lower  of  Kindle's  two  Devonian  units). 

Cooper  (5)  introduced  the  name  Little  Rock  Creek  Limestone  (=  the 
upper  of  Kindle's  two  Devonian  units)  for  7  feet  of  "gray,  brittle,  con- 
choidally  fracturing  limestone  above  the  Logansport"  that  is  exposed 
along  the  bed  and  banks  of  Little  Rock  Creek  upstream  from  the  bridge 
located  1  mile  southeast  of  Lockport,  Carroll  County   (Locality  2). 

Cooper  and  Phelan  (6)  proposed  the  name  Miami  Bend  Formation 
for  the  gray,  stromatoporoid-bearing  limestone  that  formerly  was 
included  as  the  lower  part  of  the  Logansport  Limestone  (7).  They  desig- 
nated the  west  side  of  the  France  Stone  Company  quarry  (Locality  5)  as 
type  section.  Here  the  unit  is  a  biostrome  about  15  feet  thick  and 
consists  of  gray,  fine-grained,  indistinctly  bedded,  stromatoporoid-  and 
coral-bearing  limestone  that  disconformably  overlies  the  Kokomo  Lime- 
stone Member  of  the  Salina  Formation  (Silurian). 

All  three  Middle  Devonian  limestone  units  may  be  observed  resting 
disconformably  on  Silurian  strata  along  the  Wabash  River.  The  Ken- 
neth Limestone  Member  (probably  Silurian  in  age)  of  the  Salina 
Formation  is  not  present  at  any  of  the  studied  localities. 

Conodont  Faunas 

The  Miami  Bend,  Logansport,  and  Little  Rock  Creek  units  all  con- 
tain characteristic  upper  Middle  Devonian  (Givetian)  conodont  species. 
The  Miami  Bend  (sampled  at  Localities  5  to  7)  is  a  stromatoporoid-coral 
biostrome  that  yields  small  numbers  of  conodonts.  Platform  species 
include  only  Icriodus  latericrescens  latericrescens  Branson  and  Mehl  and 
/.  expansus  Branson  and  Mehl.  At  these  three  localities  the  Miami  Bend 
is  overlain  along  a  sharp  contact  by  the  granular  Logansport  Limestone, 
the  lower  part  of  which  contains  a  conodont  fauna  identical  to  that  of  the 
Miami  Bend.  At  Locality  6,  the  upper  part  of  the  Logansport  contains 
Polygnathus  varcus  Stauffer  in  addition  to  the  above  two  taxa.  At  Local- 
ities 2  to  4-,  I.  latericrescens  latericrescens,  I.  expansus,  I.  cymbiformis 
Branson  and  Mehl,  P.  varcus,  and  P.  linguiformis  linguiformis  Hinde  are 
irregularly  distributed  throughout  the  Logansport.  The  conodont  fauna 
of  the  Little  Rock  Creek  (sampled  at  Localities  1  and  2)  is  identical  to 
that  of  the  Logansport  at  Localities  2  to  4-  listed  above. 

Correlation 

The  above  faunas  show  that  two  conodont  zones  are  present  in 
Middle  Devonian  strata  of  the  Logansport  Sag.  The  lower  is  character- 
ized by  the  presence  of  Icriodus  latericrescens  latericrescens  below  the 
lowest  position  of  Polygnathus  varcus.  The  upper  is  the  P.  varcus  Zone 
(25)  that  is  characterized  by  the  association  of  these  two  taxa. 

In  Germany,  Icriodus  latericrescens  latericrescens  is  confined  to  the 
Polygnathus  varcus  Zone  high  in  the  Givetian  Stage  (24).  In  North 
America,  /.  latericrescens  latericrescens  is  widely  distributed  below  the 


Geology  and  Geography  337 

P.  varcus  Zone  and  in  New  York  ranges  from  the  Levanna  Shale  Member 
of  the  Skaneateles  Shale  (Hamilton  Group)  into  the  Tully  Formation. 
Polygnathus  varcus  ranges  from  the  Centerfield  Limestone  Member  of 
the  Ludlowville  Shale  (Hamilton  Group)  also  into  the  Tully  (14).  See 
Orr  and  Klapper  (18)  for  a  discussion  of  the  correlation  of  this  interval. 

In  the  Logansport  Sag,  the  Miami  Bend  and  the  lower  part  of  the 
Logansport  lie  within  the  zone  of  Icriodus  later  icrescens  later icrescens 
below  the  lowest  position  of  Polygnathus  varcus.  In  the  Michigan  Basin, 
the  lower  part  of  the  Traverse  Formation  (20)  of  northern  Indiana  and 
that  part  of  the  Traverse  Group  of  Michigan  below  and  including  the 
lower  part  of  the  Alpena  Limestone  lie  within  this  conodont  zone  (17). 
The  highest  part  of  the  Silver  Creek  Member  of  the  North  Vernon 
Limestone  of  southern  Indiana  also  lies  within  this  zone   (19). 

The  upper  part  of  the   Logansport  and  the  Little  Rock  Creek  lie 

within  the  Polygnathus  varcus  Zone.  In  the  Michigan  Basin,  the  upper 
part  of  the  Traverse  Formation  of  northern  Indiana  and  that  part  of  the 
Traverse  Group  of  Michigan  above  and  including  the  middle  part  of  the 
Alpena  Limestone  to  the  base  of  the  Squaw  Bay  Limestone  lie  within  this 
conodont  zone  (17).  In  southern  Indiana,  the  Beechwood  Member  of  the 
North  Vernon  Limestone  lies  within  the  P.  varcus  Zone  (16). 

Cooper  and  others  (8)  correlated  the  Logansport  with  the  Beechwood 
Member  of  southern  Indiana  and  with  the  Four  Mile  Dam  Limestone  of 
Michigan.  They  considered  the  Little  Rock  Creek  to  be  younger  than  the 
Beechwood  and  correlated  it  with  the  Potter  Farm  Formation  and 
Thunder  Bay  Limestone  (both  of  the  Traverse  Group)  of  Michigan. 
Campbell  (3)  also  correlated  the  Devonian  rocks  exposed  at  Pipe  Creek 
Falls  with  the  Beechwood  on  the  basis  of  megafaunal  similarities. 

Galloway  and  St.  Jean  (11)  studied  the  stromatoporoid  faunas  of 
both  the  Logansport  and  Little  Rock  Creek  units.  They  indicated  the 
Hamilton  age  of  the  Logansport  fauna  and  pointed  out  the  correlation 
with  Frasnian  and  Faminian  faunas  from  the  Dinant  Basin,  Belgium. 
They  considered  the  Little  Rock  Creek  to  be  of  Tully  age  and  correlated 
its  stromatoporoid  fauna  with  that  of  the  Potter  Farm  Formation  of 
Michigan. 

In  1966  Cooper  and  Phelan  (6)  reported  for  the  first  time  the 
brachiopod  String  ocephalus  in  Indiana.  They  obtained  their  specimens 
from  the  Miami  Bend  unit  at  several  localities  just  east  of  Logansport 
including  the  upper  18  inches  of  the  unit  in  the  west  wall  of  the  France 
Stone  Company  quarry  (Locality  5).  On  the  basis  of  brachiopod  faunas, 
Cooper  and  Phelan  correlated  the  Miami  Bend  with  the  Rogers  City 
Limestone  of  the  Michigan  Basin  and  with  an  interval  in  New  York 
between  the  Marcellus  and  Skaneateles  Shales.  In  terms  of  conodont 
zones,  the  Miami  Bend  lies  within  the  same  zone  as  the  Skaneateles 
Shale  of  New  York. 

Cooper  and  Phelan's  (6)  correlation  of  the  Miami  Bend  with  the 
Beauvais  Sandstone  of  Ste.  Genevieve  County,  Missouri,  is  herein  rejected

tus  Stewart  and  Sweet.  This  important  species  is  found  also  in  the 
Dundee  Limestone  of  northwest  Ohio  (14),  Delaware  Limestone  of  cen- 
tral Ohio  (21),  and  lower  part  of  the  intertonguing  Speed  and  Silver 
Creek  Members  of  the  North  Vernon  Limestone  of  southern  Indiana  (16). 
The  correlation  of  these  units  with  the  Marcellus  Shale  of  New  York  is 
well  established. 

Nomenclatural  Proposal 

Thornbury  and  Deane  (22)  and  Pinsak  and  Shaver  (15)  previously 
have  pointed  out  the  lithologic  affinities  of  the  Middle  Devonian  rocks  of 
the  Logansport  Sag  to  Traverse  rocks  of  the  Michigan  Basin.  The 
Miami  Bend,  Logansport,  and  Little  Rock  Creek  units  represent  a  south- 
ern extension  of  southward-thinning  Traverse  strata  into  the  Sag.  The 
Four  Mile  Dam  Limestone  of  Michigan  and  the  Miami  Bend  unit  repre- 
sent similar  biostromal  developments  of  similar  Late  Givetian  age. 
The  conodont  faunas  of  the  Middle  Devonian  rocks  of  the  Sag  are  essen- 
tially identical  to  those  of  Traverse  strata  of  the  Michigan  Basin. 

Because  of  lithologic  similarities,  similar  depositional  histories,  and 
equivalent  conodont  faunas,  it  is  here  proposed  that  the  name  Traverse 
Formation  (20)  be  used  for  those  rocks  in  the  Sag  that  previously  have 
been  designated  as  Miami  Bend  Formation,  Logansport  Limestone,  and 
Little  Rock  Creek  Limestone.  The  extension  of  the  name  Traverse  into 
the  Logansport  Sag  is  consistent  with  Middle  Devonian  paleogeographic 
interpretations  of  Pinsak  and  Shaver  (15)  and  eliminates  needless  nomen- 
clature applicable  to  outcrops  in  a  few-county  area.  In  contrast  to  the 
Miami  Bend,  Logansport,  and  Little  Rock  Creek,  the  Traverse  is  a  map- 
pable  unit  that  can  be  traced  in  the  subsurface  of  northern  Indiana  and 
the  Michigan  Basin. 

Because  the  Miami  Bend,  Logansport,  and  Little  Rock  Creek  units 
are  quite  thin,  have  unclear  lateral  relationships,  and  have  been  recog- 
nized only  in  outcrop  in  a  few-county  area,  but  do  possess  identifying 
lithologic  characteristics,  it  is  here  suggested  that  when  these  names  are 
used  they  be  assigned  the  rank  of  lithofacies  rather  than  formation.

Planning  for  and  Utilization  of  the  Web  Pattern  of 
Physical  Urban  Development  in  Cities 

Thomas  Frank  Barton,  Indiana  University 

In  two  earlier  papers,  (1,  2)  the  writer  identified  and  described  a 
web  pattern  of  physically  urban  development  consisting  of:  1.  business- 
industrial-circulation  corridors  with  residential  meshes  located  in  urban 
areas  and  2.  a  web  of  corridors  of  urban  development  in  the  countryside 
enclosing-  farm  and  forest  lands. 

This  paper  recommends  that  rather  than  permitting  a  web  of  busi- 
ness-industrial-circulation corridors  to  develop  haphazardly,  American 
city  planning  departments  should  design  and  zone  a  web  of  these  corri- 
dors. There  are  seven  primary  advantages  in  taking  this  progressive 
and  decisive  planning  and  zoning  action: 

1.  Aids  industry  by  (a)  providing  for  wider  and  more  even  distribution 
of  business  and  industry  throughout  the  urban  area  and  thereby 
helping  rlatively  to  relieve  congestion  in  the  downtown;  (b)  permit- 
ting concentration,  yet  dispersal,  of  industry;  (c)  increasing  the 
opportunity  for  the  number  of  and  greatly  increasing  the  foot- 
frontage  for  strategic  industrial  sites  fronting  on  (or  nearby)  major 
transportation  lines  and  primary  utility  lines;  and  (d)  making  possi- 
ble more  efficient  location  of  industrial  districts. 

2.  Provides  for  nodal  business  development. 

3.  Permits  better  location   of  trucking  terminals  and  warehouses. 

4.  Makes  possible  better  siting  of  high  rise  apartments. 

5.  Enables  utilities  to  provide  more  efficient,  economical  service. 

6.  Helps  concentrate  populations  and  travel  destinations  thereby  sup- 
porting existing  or  potential  mass  transit. 

7.  Protects  and  helps  make  more  viable  and  liveable  neighborhood  and 
community  residential  areas. 

Aid  Industry 

Better  city-wide  distribution.  Today  in  many  American  cities  too 
much  industry  is  concentrated  near  the  business-industrial  core  of  the 
city  or  has  migrated  to  peripheral  and /or  suburb  locations.  If  too  high 
a  fraction  of  the  city's  employment  opportunities  is  concentrated  in  the 
downtown,  traffic  congestions  at  morning  rush  hours  will  be  caused 
primarily  by  too  many  people  converging  from  various  directions  of  the 
compass  to  a  relatively  smaller  and  smaller  area.  In  contrast  if  relatively 
too  many  businesses  and  industries  are  located  on  the  periphery  of  a 
large  city  in  political  suburbs,  the  lower  income  bracket  group  of  em- 
ployees finds  it  impossible,  difficult  or  expensive  to  make  their  journeys 
to  work.  Moreover  the  central  city  is  hard  pressed  to  maintain  a  suffi- 
ciently high  tax  base  to  support  city  services.  The  zoning  of  a  web  of 

342 


Geology  and  Geography  343 

business-industrial-circulation  corridors  not  only  encourages  the  city- 
wide  distribution  of  business  and  industry  instead  of  having  them  con- 
centrated in  large  islands  or  on  one  or  more  edges  of  the  downtown  but 
such  zoning  will  also  reduce  if  not  prevent  future  scatteration  of  these 
establishments  on  city  peripheries  where  they  may  be  subsequently  en- 
gulfed by  residential  subdivisions.  In  contrast,  industries  and  businesses 
built  in  these  corridors  are  protected  from  encroachment  and  enclosure 
by  residential  sub-division  promoters.  Owners  of  industries  now  scattered 
throughout  the  residential  areas  should  be  instructed  not  to  expand  or 
make  improvements  in  their  present  plants.  Moreover  any  industries 
wishing  to  locate,  expand  or  relocate  should  be  helped  to  secure  new 
sites  in  the  corridors.  Present  owners  of  residences  in  the  newly  desig- 
nated corridors  should  be  advised  not  to  improve  their  property  and 
to  be  encouraged  to  find  new  locations.  Within  a  few  decades  if  not 
earlier  the  scatteration  of  industries  in  residential  areas  and  of  resi- 
dences in  the  business-industrial  corridors  could  be  materially  reduced 
and  primarily  eliminated. 

Permits  concentration  yet  dispersal.  The  web  pattern  with  its  corri- 
dors will  provide  an  alternate  choice  to  the  management  of  new  or  ex- 
panding businesses  and  industries  that  do  not  wish  to  choose  between 
two  extremes.  These  extremes  are:  1.  staying  in  the  downtown  area 
or  2.  locating  on  the  edge  of  the  city.  The  web  pattern  of  corridors  pro- 
vides a  large  number  of  locational  opportunities  between  the  center  of 
the  city  and  its  edges  and  in  relation  to  other  major  considerations  such 
as  an  airport  or  a  university. 

When  business  and  industry  are  widely  dispersed  over  the  city  in 
corridors,  there  is  a  greater  opportunity  for  more  people  to  live  in  the 
residential  meshes  of  the  web  pattern  and  be  closer  to  their  places  of 
employment.  In  this  way  those  employed  in  a  nearby  corridor  may  save 
hours  each  day  and  have  transportation  costs  reduced  in  their  journeys 
to  work  and  shop  and  to  secure  services  and  recreation.  This  will  also 
relieve  at  least  relatively  downtown  congestion. 

Increases  strategic  industrial  sites.  Efficient,  quick,  low  cost  trans- 
portation is  vital  to  most  businesses  and  industries.  The  amount  of  land 
adjacent  to  nodal  areas,  produced  by  the  junctions  and  crossings  of 
several  types  of  transportation  such  as  highways,  railways,  water- 
ways and  airways  is  limited.  However  in  business-industrial  corridors 
where  railroad  lines,  limited  access  expressways  and  subways  are  built 
roughly  parallel  to  each  other  for  miles  and  miles,  the  land  fronting 
on  these  lines  (or  located  within  a  block  or  two)  is  increased  enormously. 
At  the  present  time  in  many  cities  railroad  lines  and  limited-access  ex- 
pressways parallel  to  each  other  or  perhaps  one  or  two  miles  apart 
extend  for  long  distances  through  residential  areas  where  their  presence 
is  considered  a  nuisance  if  not  an  economic  and  social  liability.  With  the 
development  of  corridors:  1.  transportation  line  right-of-ways  are  re- 
stricted to  compact  areas,  2.  the  transportation  facilities  can  be  co- 
ordinated to  give  more  efficient  service,  3.  frontage  sites  for  industry 
and  to  a  lesser  extent  for  business  are  increased  by  linear  development 


344  Indiana  Academy  of  Science 

and  4.  single-dwelling  residential  areas  may  be  better  shielded  with 
parkways,  high-rise  apartments  and  semi-public  buildings.  In  this  manner 
residential  land  adjacent  to  but  not  fronting  on  transportation  lines  has 
its  value  increased  rather  than  decreased. 

Of  course  each  corridor  will  not  have  a  railroad,  subway  and  ele- 
vated line  but  each  corridor  will  be  served  by  a  major  limited  access  ex- 
pressway consisting  of  4  to  12  lanes  or  more. 

Efficient  location  of  industrial  districts.  The  zoning  of  business- 
industrial  corridors  and  the  provision  of  adequate  transportation  and 
utility  facilities  reduces  the  competition,  pressure  and  scramble  for 
industrial  sites  and  encourages  the  sorting  of  industries  into  roughly 
homogeneous  groups.  Some  industries  have  clean  facilities,  use  clean  raw 
materials  and  are  on  well-landscaped  grounds.  These  industries  desire 
prestigious  environments  and  wish  to  be  in  a  cluster  of  similar  indus- 
tries rather  than  adjacent  to  plants  with  extensive  truck  activity  and 
open-lot  storage  of  raw  materials  which  at  best  give  a  cluttered,  un- 
sightly appearance.  In  the  corridors  tertiary  industries  using  raw  ma- 
terials delivered  to  the  plant  by  truck  and  airplane  would  be  located  in 
one  section  and  secondary  industries  using  railroad  cars  and  ship  or 
barge  loads  of  coal,  ores,  lumber  and  other  materials  could  more  con- 
genially and  efficiently  occupy  a  different  one.  The  former  could  be 
adjacent  to  an  airport  and  the  latter  an  ocean,  lake  and/or  river  port. 

Encourages  Nodal  Business  Development 

Although  nearly  all  large  cities  with  populations  of  about  250  thou- 
sand or  more  (as  well  as  many  cities  of  smaller  size)  have  extensive  com- 
mercial strips  or  ribbon  development  occupying  net  patterns,  most  of 
the  city  planning  departments  are  attempting  to  discourage  and/or  block 
this  development.  Long-range  plans  shown  on  land  use  maps  indicating 
future  city  goals  show  a  hierarchy  of  business  nodal  areas  ranging  in 
size  from  the  neighborhood  through  the  community  to  the  regional 
shopping  and  service  areas  with  the   apex  in  the  downtown. 

If  land  were  zoned  and  developed  as  business-industrial  corridors, 
business  could  be  more  easily  and  justifiably  restricted  to  corridor  junc- 
tions with  the  regional  centers  at  the  major  junctions  and  the  community 
centers  at  the  secondary  junctions.  The  same  transportation  and  utility 
systems  would  serve  both  urban  land-use  functions — business  and  in- 
dustry. Ribbon  development  should  be  reduced  and  discouraged  and  in 
time  primarily  eliminated.  Zoning  would  prevent  industry  from  occupying 
nodal  corridor  junctions  which  provide  strategic  sites  for  retail,  service 
and  recreational  establishments.  Moreover  zoning  would  prevent  retail 
establishments  from  occupying  scattered  sites  that  become  dispersed  in 
a  nuisance  fashion  among  the  industries. 

Better  Location  of  Truck  Terminals  and  Warehouses 

Without  business-industrial  corridors  strategic  sites  for  trucking 
terminals  and  warehouses  wax  and  wane.  Moreover  in  some  cities  the 


Geology  and  Geography  345 

zoning  departments  are  attempting  to  concentrate  these  facilities  in 
one  large  area  on  one  side  of  the  downtown.  However  different  types  of 
trucking  terminal  and  warehouses  should  be  grouped  in  districts  adjacent 
to  the  types  of  businesses  and  industries  they  service.  Warehouses  could 
be  located  in  the  corridors  fronting  on  or  within  a  few  blocks  of  limited 
access  expressways,  railroad  lines  and  water  transport  or  airfields. 

Siting  High-Rise  Apartment  Districts 

With  the  businesses,  industries,  and  transportation  concentrated  in 
corridors  which  enclose  the  residential  meshes,  at  least  two  general  types 
of  high  rise  apartment  sites  become  available.  These  may  be  found  adja- 
cent to  and  flanking  the  corridors  or  near  the  center  of  the  communities 
enclosed  in  the  meshes.  The  writer  would  like  to  see  many  of  the  high 
rise  apartments  occupying  an  open-space  greenbelt  of  parkways  which 
would  help  to  screen  the  corridors.  Some  of  the  more  expensive  high- 
rise  apartments  could  overlook  the  better  landscaped  industrial  districts. 
Apartments  for  the  less  affluent  and  perhaps  hand  and  semi-skilled  labor- 
ers could  be  located  adjacent  to  the  secondary  industries  where  their 
employment  is  located.  No  attempt  would  be  made  to  segregate  income 
groups.  The  primary  criterion  would  be  to  locate  types  of  apartment 
house  suitable  for  the  non-management  employees  as  near  potential 
places  of  employment  as  possible  so  as  to  reduce  the  time  spent  in 
going  to  and  from  work. 

Bicycling  and  walking  to  work  which  is  so  commonplace  in  Europe 
would  then  become  potentially  possible  for  many  here  in  the  United 
States.  If  this  type  of  travel  were  adopted,  automobile  traffic  could  be 
relatively  reduced  and  perhaps  the  worker's  health  improved. 

More  Efficient  Utility  Service 

If  retail,  wholesale,  service  and  industrial  establishments  were  lo- 
cated in  corridors  with  high-rise  apartments  flanking  them,  utility  man- 
agements might  become  believers  in  the  philosophy  that  a  "little  bit  of 
heaven  or  paradise"  can  exist  on  earth.  These  corridors  then  would  be- 
come the  sites  of  the  primary  arterials  of  water,  sewage,  gas,  electricity, 
telephone  and  other  services.  Tributary  lines  would  connect  the  single- 
house,  duplex  and  townhouse  apartment  residential  areas  in  the  meshes 
with  the  primary  lines  in  the  corridors.  This  would  relatively  reduce  both 
construction  and  maintenance  costs  and  provide  better  service.  For 
example,  better  pressures  could  be  maintained  in  water  systems  and 
periods  of  interrupted  service  reduced.  The  present-day  maze  of  utility 
requirements  found  in  many  cities  hinders  efficient  management.  Busi- 
ness-industrial corridor  development  would  help  bring  order  out  of  chaos. 

Mass  Transit 

Billions  of  words  have  been  written  to  support  the  theme  that  gaso- 
line-engine traffic  is  choking  and  doing  almost  irreparable  damage  to  not 
only  the  downtowns  but  entire  large  cities.  And  many  urban  leaders  ask 
why  mass  transit  is  not  economical  and  feasible?  Still  others  in  thought- 


346  Indiana  Academy  of  Science 

less  exasperation  recommend  that  mass  transit  be  subsidized  by  govern- 
mental funds.  Such  people  apparently  forget  that  mass  transit  lines  are 
going  out  of  business  each  decade  because  most  people  prefer  to  use  their 
own  car  rather  than  mass  transit.  Such  transit  is  only  feasible  when 
large  numbers  of  people  wish  to  use  such  transportation  to  reach  a  con- 
centration of  mass  destinations.  It  is  interesting  to  note  that  one  of  the 
largest  cities  in  North  America,  where  mass  transit  has  been  relatively 
successful,  has  adopted  a  long-range  plan  for  developing  through  zoning 
business-industrial  corridors. 

Permits  Community  Development 

By  designing  the  location  of  the  corridors,  the  size  of  the  resi- 
dential areas  enclosed  by  such  may  be  controlled  to  the  extent  that 
each  mesh  would  have  large  enough  space  for  at  least  several  (four  to 
five)  neighborhoods  and  one  community.  Some  residential  meshes  may 
have  several  communities.  But  the  areas  for  these  neighborhoods  and 
communities  should  be  ample  to  accommodate  single-house,  duplex  and 
town  apartments,  as  well  as  neighborhood  and  community  schools,  play 
grounds  and  shopping  centers. 

Unplanned  yet  rapidly  developing  web  patterns  of  business-indus- 
trial corridors  have  enclosed  or  are  slicing  through  residential  areas 
dividing  and  subdividing  neighborhoods  and  communities.  These  un- 
planned and  non-designed  corridors  are  yearly  destroying  billions  of 
dollars  in  undeterminable  residential  values  and  destroying  or  helping 
to  block  community  development. 

Conclusion 

The  writer's  paper  entitled  "The  Web  Hypothesis  of  Physical  Urban 
Growth"  (2)  was  written  primarily  to  call  attention  to  and  to  identify  a 
new  hypothesis  or  generalization  concerning  the  physical  pattern  of 
city  growth,  and  to  show  how  the  urban  web  pattern  with  its  business- 
industrial  threads  or  corridors  encloses,  and  as  growth  continues,  sub- 
divides residential  areas  and  produces  residential  islands  of  various  sizes. 
The  partially-enclosed  residential  areas  both  within  and  on  the  periphery 
of  the  web  pattern  indicate  that  additional  subdivisions  of  residential 
areas  will  occur. 

Although  written  in  November,  1966,  that  paper  contained  the  fol- 
lowing two  paragraphs: 

"Even  in  its  initial  step  (of  formation),  this  hypothesis  may 
aid  city  planning  by:  1.  helping  to  justify  the  planning  and  con- 
structing of  both  city  and  private  services  in  the  new  primary  arte- 
ries on  fringes  of  the  geographic  city  before  the  construction  of 
stores,  offices  and  factories  begins,  2.  supplying  a  defense  for  the 
zoning  of  land  along  the  primary  arterials  for  business  and  industry 
and  3.  zoning  the  location  of  business-industrial  corridors  to  regu- 
late the  size  of  residential  communities  so  that  these  may  be  more 
economical  and  viable. 


Geology  and  Geography  347 

In  fact,  the  development  of  multiple  distribution  systems — of 
streets  and  transit  lines;  water,  storm  water  and  gas  lines;  below- 
surface  telephone  and  electrical  wires  and  other  forms  of  transporta- 
tion, utilities  and  communication  both  public  and  private — may  pro- 
vide the  means  of  helping  control  patterns  of  urban  development." 

And  after  these  preceding  two  paragraphs  were  written  the  writer 
obtained  a  copy  of  The  Comprehensive  Plan  of  Chicago  in  which  "Corri- 
dors of  High  Accessibility"  with  associated  "Industrial  Areas"  are 
shown  (3). 

This  paper  has  stressed  seven  major  advantages  of  zoning  a  city- 
wide  pattern  of  business-industrial-circulation  corridors  for:  1.  long- 
established  cities,  2.  potential  urban  areas  on  the  perpheries  of  cities,  3. 
megalopolises  and  4.  potential  large  new  cities  (over  100,000  popula- 
tion).

Transportation  of  Mineral  Aggregates  in  Indiana1 

Robert  R.  French,  U.  S.  Bureau  of  Mines 

Abstract 

Mineral  aggregates,  such  as  crushed  stone,  sand,  and  gravel,  are  essen- 
tial to  the  expansion  and  renewal  of  urban  areas  and  to  the  improvement 
of  highway  systems.  Because  of  the  mineral  producer's  ability  and  willing- 
ness to  improve  production  techniques  and  to  absorb  increasing  costs,  the 
price  of  mineral  aggregates  has  remained  remarkably  stable.  The  stability 
of  f.o.b.  prices,  depletion,  and  the  exclusion  by  zoning  of  some  well-located 
deposits  has  caused  transportation  costs  to  become  an  increasingly 
important  part  of  the   overall  price  of  mineral  aggregates   in   Indiana. 

Published  and  unpublished  rate  schedules  show  that  trucking  is  the 
most  economical  method  of  transporting  aggregates  up  to  a  distance  of 
about  35  miles.  Between  35  and  230  miles  railroad  rates  appear  to  be  the 
most  economical,  although  substantial  variations  exist  between  companies 
and  between  northern  and  southern  Indiana.  Barge  transportation  is  most 
economical  for  distances  of  more  than  230  miles.  Average  charges  are 
approximately  2.5  to  5  cents  per  ton  mile  plus  25  cents  per  ton  base  charge 
for  road  transport,  0.82  cents  per  ton  mile  plus  $1.40  per  ton  base  charge 
for  rail  transport,  and  0.45  cents  per  ton  mile  plus  $2.25  per  ton  base  charge 
for  water  transport. 

Introduction 

Most  mineral  aggregates,  such  as  crushed  rock,  sand,  and  gravel, 
are  low-value,  high-volume  commodities  that  are  essential  to  the  ex- 
pansion and  renewal  of  housing  units,  transportation  systems,  and  work 
facilities  for  urban  populations.  Under  normal  conditions,  the  con- 
struction commodities  can  bear  only  nominal  transportation  charges  and 
must  be  produced  as  near  the  market  area  as  is  economically,  socially, 
and  geologically  feasible. 

Numerous  economic  and  social  problems  develop  and  become  more 
serious  as  rapid  urbanization  increases  the  demand  for  construction  ma- 
terials. Producing  companies  that  have  served  a  growing  market  for  any 
length  of  time  may  ultimately  be  faced  with  increasing  operating  costs 
because  of  thicker  overburden,  higher  lift  or  longer  quarry  haul,  higher 
incidence  of  equipment  repair,  increased  pumping,  and  anti-pollution  re- 
quirements. These  problems,  however,  are  mostly  overshadowed  by  the 
proximity  of  the  production  site  to  the  market  area.  The  economic  ad- 
vantage of  good  site  location  can,  and  commonly  does,  result  in  an 
increased  number  of  complaints  about  vibration,  traffic  congestion,  noise, 
physical  danger,  and  air  and  water  pollution,  by  the  local  residents.  The 
social  incompatibility  of  producer  and  consumer  creates  a  tendency  for 
new  production  sites  to  be  selected  or  relocated  in  less  densely  populated 
areas.  However,  most  production  sites  are  selected  in  areas  served  by

good  highways  and  if  unplanned  'strip'  urbanization  occurs  along  these 
transportation  routes,  then  the  social  conflicts  are  repeated. 

Geologic  and  geographic  distribution  of  commercial  grade  deposits 
is  another  major  factor  to  be  considered  in  the  production  and  subsequent 
marketing  of  mineral  aggregates  in  an  urban  area.  Geologic  conditions  in 
Indiana  are  such  that  large  areas  in  the  northern,  southwestern,  and 
southeastern  parts  of  the  State  are  covered  with  thick  glacial  drift  and 
fine-sized  outwash,  or  are  underlain  by  sandstone,  shale,  or  thin  lime- 
stone. Aggregates,  especially  the  coarser  sizes  (plus  l1/^  inch),  must  be 
transported  into  these  areas  by  road  or  rail,  and  the  cost  is  considerable. 
For  example,  coarse  aggregates  that  are  normally  priced  about  $1.50  per 
ton  f.o.b.,  commonly  retail  for  $3.10  per  ton  in  Vincennes,  and  $2.30  to 
$3.15  per  ton  at  stockpiles  in  Indianapolis,  and  for  more  than  $4.00  per 
ton  in  South  Bend. 

The  net  effect  of  the  economic,  social,  and  geologic  factors,  and  the 
low  capital  requirements  (compared  to  other  mining  operations^)  of 
mineral  aggregate  production,  has  been  to  create  a  highly  competitive 
industry  in  Indiana.  Average  prices  of  crushed  rock,  sand,  and  gravel 
have  remained  quite  low  (the  average  price  of  sand  and  gravel  was  $0.94 
and  crushed  rock  $1.27  per  ton  in  1966  as  compared  to  $0.72  and  $1.20 
per  ton,  respectively,  in  1947),  and  the  number  of  producing  quarries 
has  remained  reasonably  constant  (80  to  89)  during  the  past  20  years. 
Company  data  from  the  sand  and  gravel  industry  are  not  readily  avail- 
able, but  an  analysis  of  crushed  stone  operations  in  Indiana  (2)  has 
shown  that  most  of  the  35  independent  company  failures  that  occurred 
between  1947  and  1965  were  in  areas  where  production  facilities  were 
relatively  concentrated  (5  to  10  quarries  within  20  miles).  Most  of  the 
failures  in  these  highly  competitive  areas  are  believed  to  be  the  result 
of  both  the  market  size  and  the  minimization  of  the  protective  effect  of 
transportation  costs. 

Highway  Transport 

During  the  first  quarter  of  the  twentieth  century,  most  mineral  ag- 
gregates were  shipped  by  rail  or  used  in  the  immediate  vicinity  of  the 
quarry  or  pit.  Producing  companies  began  trucking  their  own  aggregate 
about  1925,  and  later,  in  the  1940's,  started  using  owner-operated  ve- 
hicles. This  was  a  workable  arrangement  for  small  single-quarry  com- 
panies but  mergers,  purchases,  and  normal  growth  brought  larger  inte- 
grated companies  and  a  definite  trend  toward  the  use  of  contract  haulers. 
Today  more  than  three-fourths  of  the  aggregate  produced  in  Indiana  is 
transported  to  the  consumer  by  trucks,  most  of  which  are  owned  by 
independent  trucking  companies. 

Contract  haulers  are  required  to  file  their  current  freight  rates 
with  the  Public  Service  Commission,  State  Office  Building,  Indianapolis. 
Typical  published  rates  for  three  independent  trucking  companies  are 
shown  in  Table  1.  The  wide  variations  in  charges  for  hauling  crushed 
rock,  sand,  and  gravel  on  a  cents  per  ton-mile  basis  suggest  that  per- 
haps some  "ghost"  rates  or  other  factors  may  be  included  in  these  data.

Haulage  rates  are,  in  fact,  commonly  bid  on  a  single  job  basis  and  de- 
pend largely  on  the  size  of  the  job  and  traffic  and  road  conditions  be- 
tween the  production  site  and  the  construction  project.  Some  of  the 
actual  1967  rates  charged  to  one  rural  producer  of  crushed  rock  are 
shown  in  Figure  1.  The  basic  charges  are  approximately  5  cents  per  ton- 
mile  for  the  first  6  miles,  3  cents  per  ton-mile  for  the  next  18  miles,  and 
2y2  cents  per  ton-mile  thereafter.  A  base  charge  of  25  cents  per  ton  was 
also  applicable.  These  charges  are  similar,  but  are  not  necessarily  identi- 
cal to  those  reported  to  be  in  effect  in  other  areas  of  the  country  (1,  4,  5, 
7)  and  Canada  (6,  8).

The  average  f.o.b.  price  of  crushed  rock  in  Indiana  is  approximately 
$1.27  per  ton,  thus  a  haul  of  about  31  miles  in  some  rural  areas  will 
effectively  double  the  price  of  the  aggregate  to  the  consumer.  In  urban 
and  some  suburban  areas,  the  transfer  distance  required  to  double  the 
f.o.b.  price  may  be  as  short  as  9  or  10  miles,  depending  mostly  on  time 
and  traffic  conditions.  The  cost  of  sand  and  gravel,  which  normally  sells 
for  less  than  $1.00  per  ton,  can  be  doubled  by  a  transfer  distance  of  only 
6  to  8  miles  in  some  densely  populated  areas. 

Rail  Transport 

Rail  transportation  is  used  to  haul  crushed  rock  and  minor  amounts 
of  sand  and  gravel  into  northern  and  western  Indiana,  and  into  the 
neighboring  states.  A  substantial  part  of  the  demand  for  crushed  rock 
in  Indianapolis  is  also  satisfied  via  rail  transport  of  material  produced 
in  the  surrounding  counties  (3).  Freight  rates  for  rail  transportation  of 
mineral  aggregates  vary  widely  and,  in  effect,  between  areas  of  the 
State.  Average  freight  rates  discussed  here  are  for  point-to-point  hauls 
as  filed  with  the  Public  Service  Commission.  Loading  and  unloading  of 
freight  cars  is  normally  the  responsibility  of  the  shipper  and  the  cost 
varies  from  about  20  to  40  cents  per  ton,  depending  upon  the  type  of 
rolling  stock  and  equipment  available. 

Variations  in  published  point-to-point  rates  range  from  about  10 
cents  per  ton-mile  to  less  than  one  cent  per  ton-mile  with  minimum 
charges  ranging  from  $0.99  to  $1.84  per  ton.  Reasons  for  these  variations 
may  include  complex  routes  requiring  one  or  more  transfers,  bulk  rates

lower  rates  were  in  effect  in  southern  Indiana  where  the  average  charge 
was  .61  cents  per  ton-mile  plus  99  cents  per  ton  minimum  charge.  In 
northern  Indiana,  where  quarries  are  few  and  moderately  long  hauls  are 
common,  the  charges  for  rail  transportation  were  approximately  .92 
cents  per  ton-mile  plus  $1.84  per  ton  minimum.  The  average  rate  for 
all  data  considered  in  Figure  2  is  .82  cents  per  ton-mile  plus  $1.40  per 
ton  minimum. 

Water  Transport 

A  few  of  Indiana's  crushed  rock  and  sand  and  gravel  operations  are 
strategically  located  along  the  bluffs  and  flood-plains  of  the  Ohio  River, 
and  are  able  to  take  advantage  of  barge  transportation  for  long  hauls. 
Company-owned  or  leased  barges  of  500  to  1,200  tons  capacity  are  used 
to  ship  aggregates  to  major  markets  in  southwestern  Indiana,  Illinois, 
Kentucky,  Ohio,  and  West  Virginia.  Contract  haulers  rates  are  not 
regulated  by  the  Interstate  Commerce  Commission,  but  are  commonly 
quoted  by  the  individual  companies  according  to  market  conditions  and 
are  subject  to  change.  In  late  1966,  one  barge  company  established  some 
point-to-point  transportation  rates  of  .3  to  1.02  cents  per  ton-mile,  f.o.b. 
in  barge,  with  a  minimum  load  of  500  tons  per  barge.  Another  company 
quoted  an  average  rate  of  .81  cents  per  ton-mile,  and  a  third  company 
quoted  .4  to  .65  cents  per  ton-mile  for  minimum  barge  loads  of  1,200  tons 
(plus  50-100  cents  per  ton  for  loading  and  100-200  cents  per  ton  for  un- 
loading.) The  data  shown  in  Figure  3  are  published  point-to-point  rates 
from  docks  in  Indiana  and  Kentucky.  Relatively  high   (compared  to  the

cost  of  aggregate)  loading  and  unloading  charges  normally  prohibit  the 
use  of  barge  transport  for  all  but  the  longer  hauls,  although  direct  load- 
ing via  conveyor  belt  from  processing  plant  to  barge  is  possible  at  some 
sites  and  permits  reduced  handling  charges  and  greater  distance  of 
economic  haul.  The  use  of  flat-deck  barges  can  further  reduce  the  cost 
of  loading  and  unloading  to  about  25-50  cents  and  50-100  cents  per  ton, 
respectively. 

Summary  and  Conclusions 

Trucking  will  probably  continue  to  be  the  dominant  mode  of  mineral 
aggregates  transportation  because  of  the  ease  of  loading  and  the  ability 
to  deliver  directly  to  the  point  of  consumption.  Factors  of  production  and 
transportation  generally  restrict  deliveries  to  within  about  35  miles  of 
the  production  site,  and  it  is  within  this  radius  that  trucking  appears  to 
be  the  most  economic  (Figure  4).  Geologic  conditions  do  not  permit 
large  scale  open  pit  production  of  mineral  aggregates  in  northern  and 
southwestern  Indiana  and  it  is  to  these  areas,  which  are  mostly  more 
than  50  miles  from  production,  that  railroads  provide  the  most  economic 
means  of  transportation.  Lack  of  suitable  crushed  rock  aggregate  in  some 
parts  of  the  neighboring  states  has  allowed  some  Indiana  deposits  that 
are  strategically  located  on  the  bluffs  of  the  Ohio  River  to  be  exploited 
and  the  aggregate  shipped  by  barge  to  Illinois,  Ohio,  Kentucky,  and  West 
Virginia.  Water  transport  appears  to  be  the  most  economic  method  for 
distances  of  more  than  230  miles,  but  direct  loading  facilities  from  plant 
to  barge  may  extend  the  competitive  range.

Social  conditions  and  the  concentration  of  major  markets  on  the 
fringe  of  expanding  metropolitan  areas,  in  'satellite'  cities,  and  in  high- 
way construction  projects,  create  a  tendency  for  aggregates  producers  to 
locate  or  relocate  their  open  pit  operations  in  the  more  sparsely  popu- 
lated areas  if  geologic  conditions  and  transportation  facilities  are  amen- 
able. Thus,  continued  urbanization  and  the  depletion  of  some  of  the  cen- 
trally-located deposits  may  require  longer  transportation  hauls  than 
those  previously  considered  feasible  and  competitive.  The  cost  of  longer 
transportation  must  ultimately  be  reflected  in  higher  costs  of  construc- 
tion, assuming  no  major  changes  in  technology.  Greater  truck  or  rail- 
road car  capacity,  better  highways,  unit  trains,  and  some  economies  of 
scale  in  larger  and  more  remote  production  facilities,  will  counterbalance 
the  increased  transportation  costs  to  some  degree.  Crushed  rock  and 
stone  sand  from  underground  mines  located  within  some  urban  areas 
offer  an  alternative  to  increasing  transport  cost,  but  the  industry  has 
not  yet  developed  this  possibility  to  any  great  extent.  Land  values,  and 
the  demand  for  underground  shelters,  reservoirs,  waste  disposal  areas, 
or  constant  temperature  storage  space  may  require  that  we  examine  the 
open  space  left  within  some  urban  areas  for  the  possibility  of  obtaining 
mineral  aggregates  and  creating  usable  underground  space.

An  Economic  Appraisal  of  Reclamation  Practices  on  a  Strip  Coal 
Mine  Site  in  Greene  County,  Indiana 

R.  Michael  Dinkel  and  Lee  Guernsey,  Indiana  State  University 

Abstract 

The  main  purpose  of  this  study  was  to  ascertain  the  impact  of  very 
adverse  physical  conditions  on  reclamation  practices  and  to  determine  the 
costs  involved  in  revegetating  the  toxic  strip  mine  site.  A  number  of 
experiments  were  carried  out  in  order  to  obtain  a  comparison  of  selected 
factors  of  reclamation. 

Four  expenditures  were  analyzed  in  order  to  determine  the  total  costs 
of  reclaiming-  land  which  had  developed  a  very  harsh  environment  from 
strip  coal  mining-  operations.  These  were  the  costs  of  utilities  for  prepar- 
ing media,  the  transportation  expenses  of  delivering  the  media  for  field 
application,  the  labor  costs  of  preparing  the  test  sites  and  the  planting  of 
trees,  and  the  costs  of  materials  which  included  the  media  used,  the  plants, 
and  the  seed. 

The  total  cost  of  reclaiming  an  acre  of  land  to  trees  at  the  project  site 
was  2.4tf  per  ton  of  coal  mined  or  about  $150  per  acre.  In  contrast,  the  cost 
of  reclaiming  the  test  site  to  grass  averaged  8.4tf  per  ton  of  coal  mined  or 
about  $435  per  acre.  However,  if  the  test  site  had  more  favorable 
characteristics,    the    costs    would    have    been    greatly    reduced. 

Throughout  the  Eastern  Interior  Coal  fields  of  the  United  States, 
a  significant  percentage  of  productive  land  is  undergoing  strip  coal  min- 
ing operations.  In  this  process,  massive  machinery  is  used  to  remove  the 
overburden  of  soil  and  rocks  from  above  the  various  seams  of  coal.  The 
condition  in  which  the  areas  are  left  after  the  mineral  has  been  ex- 
tracted is  in  need  of  reclamation. 

This  study  was  conducted  to  ascertain  the  significance  of  the  physi- 
cal and  economic  factors  involved  in  the  revegetation  of  a  strip  mined 
area  was  internal  and  runoff  flows  into  strip  mined  ponds  of  the  area  and 
two  spoil  bank  ridges  at  the  Greene  County  site.  One  of  these  ridges 
was  composed  entirely  of  sandstone,  whereas  the  second  ridge  was  made 
up  primarily  of  shaly  material. 

The  slopes  of  the  project  area  were  not  too  steep  for  planted  vegeta- 
tion, but  all  the  plantings  were  made  upon  the  struck  off  surface  on  top 
of  the  two  spoil  bank  ridges.  The  ridge  tops  had  a  width  of  nearly  twenty 
feet  between  the  shoulders  of  the  banks.  Most  of  the  drainage  in  the 
area  was  internal  and  runoff  flows  into  strip  mined  ponds  of  the  area  and 
remains  stagnant  after  reaching  these  water  bodies.  This  fact  has  been 
instrumental  in  the  ponds  having  a  high  iron  content  and  a  very  reddish 
color. 

Another  physical  characteristic  of  primary  importance  is  the  soil 
texture  of  the  project  area.  The  character  of  materials  making  up  the 
spoil  surfaces  has  a  direct  effect  on  plant  growth  and  ultimate  soil  de- 
velopment. Since  the  shale  spoil  bank  had  a  much  finer  texture  than  the 
sandstone  spoil  bank,  more  compaction  occured  on  this  spoil  material  and 
resulted  in  an  impervious  hardpan  developing  on  the  shale  ridge.

The  sandstone  ridge  in  the  project  area  had  a  pH  range  of  from 
3.0  to  4.9  and  was  a  marginal  spoil  bank.  This  is  in  contrast  to  the  shale 
ridge,  which  has  an  average  pH  of  2.7  and  was  classified  as  being  toxic. 
The  non-toxic  portions  of  the  marginal  spoils  were  plantable,  but  were 
usually  small  in  size  and  randomly  scattered.  The  pH  readings  were 
taken  at  various  depths  in  the  spoil  banks.  This  was  done  since  leaching 
processes  often  cause  the  surface  spoil  to  be  less  acidic  than  that  found 
at  a  depth  of  a  few  inches.  Qualitative  chemical  tests  were  made  on  the 
spoil  from  both  strip  mine  ridges  within  the  experimental  area.  Both 
the  shale  and  the  sandstone  ridge  were  found  to  be  very  rich  in  phos- 
phorus. Traces  of  potassium,  magnesium,  and  calcium  were  also  found 
in  the  area.  Iron  was  present  in  samples  from  both  ridges,  but  was 
more  abundant  from  the  sandstone  area.  Both  ridges  had  a  very  high 
sulfate  content,  which  reduced  the  viability  of  the  various  plants  in  this 
reclamation  project. 

The  adjacent  farm  land  has  been  severely  damaged  by  the  toxic  ma- 
terial which  has  been  washed  down  from  the  spoil  banks.  Loose  material 
has  been  carried  down  onto  the  field  which  will  undoubtedly  decrease  the 
productive  capabilities  of  the  land.  This  problem  might  be  alleviated  if 
drainage  ditches  were  maintained  near  the  boundary  of  these  two 
adjacent  areas.  The  simple  construction  of  ditches  would  not  eliminate 
the  problem  because  these  ditches  would  fill  with  sediment  very  rapidly. 

One  of  the  initial  steps  in  planning  this  study  was  to  determine  a 
site  layout  for  the  experimental  plots.  Preliminary  field  work  was  con- 
ducted during  March,  1968,  to  determine  the  specific  areas  in  which  the 
experiments  would  be  conducted  upon  the  various  woody  species  to  be 
used.  Two  herbaceous  species  were  planted  in  October  of  1967,  and  simi- 
lar preliminary  work  was  done  prior  to  that  time.  Upon  evaluating  the 
slopes  of  the  two  ridges,  considering  the  exposure  of  the  different  species 
to  the  sunlight  and  the  drainage  of  the  plots,  it  was  decided  that  the  top 
of  the  two  ridges  would  be  used  for  the  plantings  of  both  trees  and 
grasses.  Since  the  sides  were  not  equal  in  degree  of  slope,  it  was  felt 
that  the  flattened  area  on  the  ridge  tops  should  be  utilized,  thus  giving  a 
more  accurate  means  of  equating  the  actual  potential  of  each  of  the  two 
ridges.  These  tops  were  struck  off  in  1966,  six  years  after  the  strip 
mining  had  taken  place. 

Definite  plots  were  then  staked  out  on  the  ridges.  A  total  of  twelve 
separate  plots  were  arranged,  with  six  being  located  on  each  ridge,  and 
trees  were  planted  at  six  foot  intervals  within  these  plots  (Figures  1 
and  2).  It  was  decided  to  use  six  different  species  of  trees  and  to  divide 
these  various  species  into  three  groupings.  Two  of  the  groups  were 
treated  with  different  fungal  culture  filtrates,  an  organic  matter  to  be 
utilized  by  the  plants  in  their  growth,  and  the  third  was  a  control  group. 
In  the  site  layout  of  experimental  plots  for  the  herbaceous  species,  less 
subdividing  of  the  plots  was  necessary.  In  this  phase  of  the  experiment, 
only  the  sandstone  ridge  was  utilized.  Prior  to  the  actual  sowing  of  the 
grasses,  the  region  was  staked  out  into  three  separate  plots  (Figure 
3).  In  comparing  the  general  physical  background  of  the  two  spoil  bank

and  the  chemical  composition  of  the  ridge  itself.  Most  of  the  other  physi- 
cal properties  were  quite  similar.

grown  on  a  volunteer  basis.  But  there  was  absolutely  no  natural  vegeta- 
tion to  be  found  surrounding  the  test  plots  on  the  shale  ridge. 

Three  separate  expenditures  were  analyzed  in  order  to  determine  the 
total  costs  of  reclaiming  land  that  had  undergone  strip  mining  opera- 
tions. These  were  the  costs  of  utilities,  labor,  and  materials  which  were 
utilized  in  the  various  aspects  of  the  reclamation  experiment.  The  shake 


360  Indiana  Academy  of  Science 

machine,  the  device  in  which  the  fungal  culture  nitrates  were  formed, 
cost  one-half  cent  per  hour  to  operate.  It  operated  for  72  continuous 
hours,  which  was  the  total  time  required  for  the  run  to  be  completed.  A 
total  of  twelve  runs  were  made  with  the  shake  machine  for  an  accumu- 
lated cost  of  $4.32.  On  a  larger  scale,  the  utilities  would  run  $43.20  to 
treat  one  acre  of  land  in  a  similar  manner.  The  utility  costs  for  the 
operation  of  the  100  gallon  fermenter,  with  96  hours  of  operation  time 
per  batch,  amounted  to  $9.85.  The  utility  cost  would  be  $197.20  for 
one  acre.  The  labor  cost  of  planting  and  treating  one  acre  of  such  land 
with  trees  would  be  approximately  $71,  based  on  the  present  minimum 
wage  of  $1.60  per  hour.

The  three  key  materials  required  for  this  research  project  were 
media  used  in  treating  the  experimental  groups,  the  plants,  and  the 
seed.  The  costs  of  these  materials  were  considered  in  order  to  determine 
a  detailed  cost  analysis  (Table  1).  The  cost  of  the  raw  materials  for 
media  used  in  the  tree  planting  experiment  was  $1.92.  From  these  costs, 
it  can  be  extrapolated  that  it  would  cost  approximately  $19.20  to  treat 
an  entire  acre  of  strip  mine  land  with  tree  plantings  in  a  similar  manner. 
It  was  necessary  to  acquire  the  tree  seedlings  for  this  study  in  multiples 
of  one  hundred.  Although  only  part  of  the  tree  seedlings  were  planted, 
one  hundred  of  each  of  the  six  different  species  of  trees  were  acquired 
and  only  the  more  healthy  specimens  were  used  in  the  actual  planting 
on  the  spoil  banks. 

By  planting  a  total  of  only  180  trees  on  the  two  strip  mine  sites, 
the  actual  cost  of  plants  used  in  the  study  was  about  $1.60.  These  were 
planted  in  an  area  which  was  approximately  4,000  square  feet  in  size.  In 
extrapolating  this  to  a  scale  of  acreage,  the  cost  of  plants  necessary  to 
reclaim  an  acre  of  similar  land  would  be  nearly  $16.  Two  grasses  were 
used  in  this  study,  Kentucky  31  Fescue  and  perennial  rye.  A  seed  mix- 
ture containing  2%  lb.  of  each  was  sown  on  the  experimental  plots.  The 
cost  of  seeding  the  plots  was  $3  and  the  sum  of  all  grass  seed  utilized  in 
the  project  totaled  $9.  The  cost  of  seeding  an  acre  of  strip  mined  land  in 
a  similar  manner  would  cost  about  $170.  Since  the  experiments  were  con- 
ducted on  a  comparatively  small  area,  the  total  cost  of  reclaiming  this 
type  of  land  would  be  much  less  if  the  practices  were  conducted  on  a 


Geology  and  Geography  361 

larger  scale,  as  most  certainly  would  be  the  case  in  state-wide  reclama- 
tion endeavors. 

Another  way  of  expressing  the  cost  analysis  of  reclamation  for  a 
larger  area  in  this  vicinity  is  on  a  tonage  basis.  This  figure  was  arrived 
at  by  using  the  average  depth  and  thickness  of  the  number  III  coal  seam, 
which  is  presently  being  mined  in  this  portion  of  Greene  County.  This 
seam,  which  averages  two  to  three  feet  in  thickness,  is  approximately 
sixty  feet  beneath  the  surface  of  the  earth.  If  these  figures  remain  uni- 
form throughout  the  project  area,  a  total  of  nearly  6,000  tons  of  coal 
would  be  mined  from  one  acre  of  ground.  In  1968,  the  average  cost  of 
recovering  this  coal  was  about  $4  per  ton.  It  would  cost  an  additional 
$.017  per  ton  of  coal  mined  to  reclaim  the  stripped  land  in  trees.  To 
this,  one  would  need  to  add  the  cost  of  labor,  which  would  amount  to 
approximately  $.007  per  ton.  Therefore,  the  total  cost  of  reclaiming  one 
acre  of  land  to  trees  at  the  project  site  would  amount  to  $149.35,  which 
would  average  2.4c  per  ton  of  coal  mined. 

The  cost  of  reclaiming  the  test  site  to  grass  land  is  more  expensive. 
The  materials  and  utilities  needed  in  this  operation  would  add  an  addi- 
tional 8.4c  to  the  cost  of  extracting  one  ton  of  coal  in  the  stripping  meth- 
ods now  in  use.  Labor  costs  would  vary  significantly,  even  on  the  local 
scale  and,  therefore,  would  be  almost  impossible  to  estimate  with  any 
degree  of  accuracy.  However,  without  the  labor  costs  being  taken  into 
consideration,  it  would  cost  $407  to  reclaim  an  area  of  1.0  acres  to  grass- 
lands. 

Conclusions 

Although  the  survival  rates  of  the  experimental  plantings  in  this 
reclamation  study  were  not  outstanding,  a  great  deal  of  information  was 
acquired  concerning  the  importance  of  the  physical  environment  on 
various  herbaceous  and  woody  species.  This  strip  mine  site  was  un- 
doubtedly one  of  the  most  adverse  areas  in  this  coal  mining  region.  Very 
few  spoil  banks  in  Greene  County,  Indiana  had  such  a  low  pH  reading 
and  such  a  high  sulphur  content.  By  simple  observing  the  project  area, 
one  was  able  to  note  the  dramatic  contrast  between  the  experimental 
planting  site  and  the  other  nearby  stripped  land,  which  had  been  natural- 
ly revegetated.  Before  any  major  steps  are  taken  in  the  reclamation  of 
a  stripped  area,  considerable  time  should  be  spent  to  thoroughly  analyze 
the  physical  characteristics  of  the  region.  Although  some  of  the  physi- 
cal characteristics  may  be  favorable,  one  poor  characteristic  may  cause 
the  project  to  be  unsuccessful. 

In  addition,  economic  factors  must  also  be  considered.  The  overall 
cost  of  reclaiming  spoil  banks  has  been  a  major  concern  of  the  private 
coal  companies.  Many  of  these  organizations  feel  that  the  initial  expense 
of  reclaiming  the  stripped  land  far  outweighs  any  possible  economic 
return  in  the  near  future.  This  concept  has  been  diminishing  rapidly, 
however,  due  to  many  successful  operations  in  the  past  few  years. 

On  most  strip  mined  areas  in  this  portion  of  Indiana,  favorable  re- 
sults would  be  achieved  by  utilizing  the  methods  practiced  in  this  study.

As  previously  shown  in  this  study,  it  would  be  possible  to  reforest  an 
acre  of  land  for  less  than  $150.  This  figure  would  include  the  cost  of  all 
plants,  culture  filtrate,  and  labor  for  the  project.  The  economic  returns 
from  this  endeavor  would  be  a  definite  asset  to  the  entire  region.  From 
the  cost  figures  arrived  at  in  this  study,  it  may  be  too  expensive  to 
plant  grasses  on  this  particular  strip  mine  site  in  Greene  County.  How- 
ever, if  the  area  possessed  more  favorable  physical  characteristics,  this 
operation  would  not  be  uneconomic,  since  income  from  the  grass  lands 
would  eventually  exceed  the  initial  investment. 


Popcorn  Production  in  Indiana1 

Lowell  I.  Dillon,  Ball  State  University 

Abstract 

Commercial  popcorn  production,  important  only  since  1890,  thoug-h 
showing-  much  fluctuation,  has  increased  greatly  since  the  early  1940's. 
National  harvested  totals  in  the  last  decade  have  averaged  approximately 
180,000  acres  and  416  million  pounds.  The  crop's  value  has  been  as  high  as 
15.4  million  dollars.  Most  production  is  in  the  Corn  Belt  with  Indiana  the 
leader  in  most  recent  years.  Production  by  various  counties  has  been  quite 
variable  but  the  chief  areas  has  recently  been  in  northeastern  Indiana  and 
particularly  Huntington  County.  Optimum  physical  conditions  and  methods 
of  cultivation  are  similar  to  those  for  field  corn  but  more  care  is  necessary 
in  harvesting  and  storage.  The  chief  reasons  for  the  importance  of  popcorn 
production  in  Indiana  are  the  government  feed  grains  allotment  program 
and  the  location  here  of  established  buyers  and  processors.  The  state 
should  continue   as   one  of   the   major  United  States   producers. 

Popcorn  was  probably  grown  by  the  Indians  of  both  North  and 
South  America.  It  has  been  important  commercially,  however,  only 
since  about  1890.  Production,  though  showing  a  great  deal  of  fluctuation 
from  year  to  year,  has  increased  greatly  since  the  early  1940's  (1).  This 
coincided  approximately  with  the  development  of  popcorn  hybrids,  but 
growing  demand  would  probably  have  caused  an  increase  anyhow.  In 
the  last  decade  the  national  harvested  area  has  varied  from  about  109,- 
000  to  over  240,000  acres  with  an  average  of  approximately  180,000 
acres.  Pounds  produced  have  varied  from  272  million  to  518  million, 
averaging  about  416  million  (Table  1),  and  value  of  the  harvest  has 
ranged  from  about  6.2  million  to  15.4  million  dollars  (2)  and  (3). 

As  shown  on  Table  1,  the  commercial  crop  is  chiefly  produced  in  the 
Corn  Belt  states  of  Ohio,  Indiana,  Illinois,  Iowa,  Missouri,  and  Nebraska, 
although  the  bordering  states  of  Michigan  and  Kentucky  produce  signifi- 
cant enough  amounts  to  be  listed  in  the  annual  reports  of  the  Department 
of  Agriculture.  Minor  amounts  are  at  times  reported  from  states  as  far 
apart  as  Maryland,  Texas,  and  Idaho.  Indiana  or  Iowa  is  usually  the 
leading  state  with  Illinois  third  (2).  The  exact  ranking  of  states  is  some- 
times questionable,  as  statistics  from  the  two  major  sources,  the  Census 
of  Agriculture  and  Agricultural  Statistics  do  not  always  agree.  Based  on 
measurements  of  the  last  ten  years  by  the  latter  source,  Indiana  is  the 
leader  in  both  harvested  acreage  and  in  total  pounds  produced. 

Within  Indiana  the  leading  producing  counties  are  scattered  widely 
over  the  state.  Huntington  County  has  been  the  leading  producer  in  the 
two  most  recent  agricultural  census  years.  Other  leading  counties  include 
Kosciusko,  LaPorte,  Vermillion,  Harrison,  Wells,  and  Noble  (Table  2). 
As  has  been  true  nationally,  there  has  been  considerable  fluctuation  of

production  from  county  to  county  within  the  state.  At  various  census 
periods  LaGrange,  Parke,  Tippecanoe,  and  Vigo  Counties  have  ranked 
high  (4).  In  the  post-war  period  the  most  stable  areas  of  important  pro- 
duction have  been  in  northeastern  Indiana  in  Huntington,  Wells,  Noble, 
and  Kosciusko  Counties.  Even  here,  however,  stability  is  only  relative 
and  there  have  been  significant  changes  from  year  to  year  in  both  acreage 
and  production. 

Here  the  question  arises  as  to  why  Indiana  is  a  leading  popcorn  pro- 
ducer and  why  popcorn  production  is  of  major  importance  in  certain 
counties  and  not  in  others. 

The  usual  methods  of  commercial  popcorn  growing  are  very  similar 
to  those  used  for  field  corn  (1).  Physical  conditions  of  climate  and  soil 
which  encourage  the  growth  of  one  also  encourage  the  other.  Some 
growers  claim  that  a  somewhat  slower  ripening  period  is  better  for  pop- 
corn. This  would  favor  the  more  northern  Corn  Belt  areas.  This  surely 
is  only  a  minor  factor.  It  has  not  significantly  discouraged  growers  in 
such  areas  as  southern  Indiana  and  Kentucky. 

Methods  of  planting  and  cultivation  are  nearly  identical  and  fertiliza- 
tion varies  only  slightly.  There  are  major  differences,  however,  in  har- 
vesting and  curing  the  crop.  While  a  mechanical  com  picker  can  be 
easily  adapted  to  harvest  popcorn,  this  crop  is  always  harvested  as  ear 
corn.  Most  field  corn  is  both  picked  and  shelled  in  the  field.  Further, 
damage  to  the  standing  crop  by  wind,  rain,  or  hail  may  have  a  more 
serious  effect  on  the  harvesting  of  popcorn  than  on  that  of  field  corn. 
Popcorn  is  more  susceptible  to  picking  damage  than  field  corn  since 
cracked  or  broken  kernels  are  useless  for  popping. 

Storage  and  curing  practices  are  also  much  more  important  in  the 
production  of  popcorn.  Since  popcorn  is  grown  for  human  consumption, 
standards  are  higher  than  for  field  corn  and  rodent  or  insect  damage 
may  make  the  crop  completely  unacceptable  to  the  processor.  In  this  case 
the  farmer  can  only  use  his  popcorn  for  animal  feed,  a  use  for  which 
field  corn  is  far  more  suitable. 

Moisture  content  is  also  of  paramount  importance.  The  crop  should, 
if  possible,  be  completely  mature  before  the  first  killing  frost,  and  slow 
natural  drying  in  the  field  or  crib  is  recommended.  Artificial  drying,  how- 
ever, is  common  but  must  be  done  carefully.  Too  rapid  loss  of  moisture 
may  reduce  popping  expansion  resulting  in  a  lower  price  or  loss  of 
market. 

Such  differences  in  harvesting  or  curing,  however,  are  not  the  major 
factors  involved  in  the  decision  of  whether  or  not  to  grow  popcorn.  The 
greatest  differences  in  field  corn  and  popcorn  production  and  the  most 
important  determinants  in  the  farmer's  choice  of  crops  are  governmental 
and/or  economic. 

The  government  feed  grains  program  is  of  major  importance.  Under 
this  program  the  acreage  allotted  to  a  farm  for  the  growing  of  corn, 
wheat,    sorghums,    and    other   feed    grains   has    been    calculated    on    the

basis  of  the  acreage  planted  in  these  crops  in  the  1958-1959  base  year. 
This  has  affected  popcorn  production  in  two  ways.  In  some  parts  of 
Indiana  farmers  were  at  that  time  already  growing  popcorn  fairly  exten- 
sively. Their  acreage  allotment  for  feed  grains  was  thus  somewhat  low 
when  compared  to  their  total  farm  acreage.  The  farmer  thus  is  encour- 
aged to  continue  to  use  his  unallotted  land  for  popcorn  or,  for  the  only 
other  real  cash  crop  choice,  soybeans.  This  has  tended  to  cause  permanent 
popcorn  production  by  the  same  farmers  over  a  longer  period  of  time. 

Acreage  allotments  have  also,  since  they  restrict  the  planting  of 
feed  grains,  left  surplus  land  available  for  crops  not  covered  by  the 
federal  programs  and  have  encouraged  some  farmers  who  had  not  grown 
popcorn  previously  to  enter  into  this  type  of  agriculture.  Again,  as  men- 
tioned above,  the  only  real  cash  crop  choice  is  soybeans.  The  crop  planted 
will  depend  upon  the  farmer's  opinion  as  to  which  will  be  the  more 
profitable.  In  the  case  of  popcorn  he  will  have  a  more  exact  idea  of 
his  profit  since  in  most  cases,  a  definite  price  has  been  promised  him  and 
the  only  variables  are  yield  and  quality.  Also,  he  may  get  a  bonus  if 
quality  is  especially  good. 

Although  all  the  above  factors  no  doubt  affect  the  farmer's  decision 
and  play  a  part  in  the  concentration  of  popcorn  production  in  certain 
areas,  the  most  important  determinant  is  the  location  of  an  established 
processor.  The  processor  has  the  necessary  equipment  for  drying,  shell- 
ing, storage,  and  packaging;  has  wholesale  and  retail  markets  available; 
has  transportation  facilities;  and  keeps  a  close  eye  on  national  demand 
and  holdover  supplies.  Based  on  this  knowledge  he  makes  his  acreage 
contracts  for  the  year.  He  makes  a  firm  promise  as  the  price  per  pound 
harvested,  granted  acceptable  quality,  and  for  all  practical  purposes, 
determines  the  annual  acreage  planted.  Very  few  farmers,  unless  they 
are  also  processors,  are  prepared  to  make  the  investment  in  time  and 
money  required  and  to  take  a  chance  on  the  future  market. 

No  one  can  be  definite  as  to  the  future  trends  in  popcorn  production 
generally.  Factors  involved  include  the  general  economic  prosperity  of 
the  country,  competition  from  the  myriads  of  other  "snack  foods"  now  on 
the  market  or  to  be  developed  in  the  future,  and  possible  expansion  of 
foreign  markets.  Even  now  popcorn  is  being  exported  to  Japan  and  to 
western  Europe  in  small  amounts.  Future  growth  of  these  markets 
depends  on  successful  educational  and  promotional  campaigns.  There 
may  also  be  some  other  possible  markets  as  yet  untapped  in  relatively 
prosperous  areas  of  the  world,  but  the  vast,  underdeveloped  regions  offer 
little  encouragement. 

Indiana  will  probably  continue  as  a  major  producer.  The  present 
markets  built  up  by  Indiana  processors  and  lower  shipping  costs  to  the 
populous  eastern  states  should  insure  our  state  a  continued  important 
share  of  total  national  production.

Academic  Origins  of  Members  of  the  Genetics  Society  of  America 

Donna  Howard  and  Thomas  R.  Mertens,  Ball  State  University 

Abstract 

The  academic  and  geographic  origins  of  current  members  of  the 
Genetics  Society  of  America  who  received  their  undergraduate  degrees  from 
U.  S.  institutions  and  who  are  listed  in  the  1965  edition  of  American  Men  of 
Science  were  investigated.  The  1019  geneticists  included  in  this  study 
received  their  baccalaureate  degrees  from  281  different  institutions  of 
higher  education.  The  999  who  have  earned  doctorates  were  awarded  these 
degrees  by  93  different  institutions.  Land-grant  and  state  colleges  and 
universities  were  productive  of  geneticists  at  both  the  baccalaureate  and 
doctoral  levels;  e.g.,  eight  of  the  ten  leading  institutions  granting  bacca- 
laureates to  the  geneticists  were  state  institutions,  and  over  60%  of  the 
geneticists'  doctorates  were  awarded  by  such  schools.  Over  45%  of  the 
geneticists  were  born  in  eight  states  in  the  Middle  Atlantic  and  East 
North  Central  United  States.  Of  these  eight  states,  Indiana  was  the  least 
productive,  only  20  of  the  460  geneticists  from  these  states  having  been 
born  in  Indiana.  Currently  36  of  the  1019  individuals  in  this  study  are 
employed  in  the  state  of  Indiana.  The  states  in  Southeastern  United  States 
failed  to  produce  as  many  geneticists  as  they  employ.  Only  one  state, 
Mississippi,   failed   to   produce   any   of   the   1019   geneticists. 

Introduction 

A  study  of  members  of  the  Genetics  Society  of  America  was  con- 
ducted to  reveal  the  geneticists'  academic  and  geographical  backgrounds, 
which  institutions  graduate  the  greatest  numbers  of  geneticists,  and  the 
types  of  institutions  in  which  geneticists  find  employment.  Only  the  1019 
members  of  the  Genetics  Society  of  America  who  earned  baccalaureate 
degrees  at  U.S.  institutions  and  who  were  listed  in  the  eleventh  edition  of 
American  Men  of  Science  (1)  were  included  in  this  study.  Using  this  pro- 
cedure may  be  expected  to  result  in  the  inclusion  of  active  researchers 
and  contributors  to  the  discipline  of  genetics,  and  it  eliminated  the  need 
for  sending  questionnaires  to  the  individuals  who  are  the  subjects  of  this 
investigation,  since  all  pertinent  data  were  directly  obtained  from 
American  Men  of  Science. 

The  growing  need  for  highly  trained  scientists  has  been  especially 
recognized  since  the  early  1950's.  Since  that  time  there  have  been  several 
studies  of  the  academic  backgrounds  of  scientists  in  general,  the  most 
extensive  having  been  conducted  by  Lindsey  R.  Harmon,  Director  of 
Research  for  the  Office  of  Scientific  Personnel  of  the  National  Academy 
of  Sciences.  In  his  1965  study,  Harmon  stressed  the  importance  of 
research  dealing  with  the  academic  origins  of  scientists: 

Advancement  of  the  public  welfare  and  development  of  all  aspects  of  a 
modern  technological  society  are  intimately  bound  up  with  the  educa- 
tion of  an  adequate  number  of  the  society's  members  to  the  highest 
levels  of  wbich  they  are  capable.  .  .  .  Comparatively  little  is  known, 
of  a  quantitative  nature,  regarding  the  career  patterns  of  the  most 
highly-trained  segment  of  the  populace,  and  but  little  more  is  known 
about  the  backgrounds  from  which  it  comes.   (5) 

Lyon  studied  the  origins  of  American  botanists,  and  also  stressed  the 
importance  of  researching  the  academic  origins  of  scientists:

History  of  Science  371 

Scientists  should  learn  more  about  themselves  than  is  possible  through 
personal  observations.  As  a  basis  for  maintaining  the  proper  supply  of 
trained  men  in  each  of  the  special  fields,  we  should  have  accurate 
information  about  the  number,  ages,  and  professional  preparation  of 
the  workers  in  each  area.  (8) 

The  research  most  closely  related  to  the  present  investigation  is 
Chiscon's  "The  Academic  Origin  of  Drosophila  Workers  in  the  United 
States"  (2).  In  his  study,  Chiscon  determined  the  academic  origins  of 
471  Drosophila  workers.  As  sources  of  data,  he  utilized  the  volumes  of 
American  Men  of  Science  and  Drosophilia  Information  Service. 

The  present  study  of  1019  members  of  the  Genetics  Society  of  Amer- 
ica identifies  those  institutions  which  have  provided  instruction  in  the 
field  of  genetics,  the  genticists*  areas  of  research  specialization,  the  types 
of  academic  backgrounds  the  geneticists  have,  the  types  of  institutions 
in  which  the  geneticists  find  employment,  and  the  regions  of  the  U.S. 
which  have  been  the  most  productive  of  geneticists. 

Materials  and  Methods 

The  names  and  current  addresses  of  the  geneticists  were  taken  from 
the  1967  membership  list  of  the  Genetics  Society  of  America  (3).  The 
1965  edition  of  American  Men  of  Science  was  used  as  a  source  for  the 
following  additional  information  which  was  recorded  on  a  5"  x  7"  card  for 
each  geneticist:  age,  sex,  date  and  place  of  birth,  degrees  earned,  institu- 
tions where  degrees  were  earned,  years  in  which  degrees  were  earned, 
age  when  degrees  were  earned,  post-doctoral  experience,  current  institu- 
tion of  employment,  and  field  of  specialization. 

The  geneticists'  ages  were  determined  from  the  birth  date  and  were 
calculated  as  of  May,  1968 — the  anticipated  completion  date  of  this  inves- 
tigation. The  World  Almanac  (10)  was  used  to  determine  whether  the 
institutions  which  granted  the  degrees  were  state,  land-grant,  denomi- 
national, private,  etc.  These  data  were  then  analyzed  in  order  to  obtain 
generalizations  about  geneticists  in  the  United  States. 

Data  and  Discussion 

Academic  origins.  The  baccalaureate  origins  of  the  geneticists  were 
more  varied  than  the  doctoral  origins.  There  were  three  times  as  many 
baccalaureate  institutions  as  there  were  doctorate  institutions.  The  1019 
baccalaureates  earned  by  the  geneticists  were  awarded  by  281  different 
undergraduate  institutions.  One  hundred  forty  institutions  awarded  only 
one  baccalaureate,  while  53  each  awarded  two  such  degrees.  The  remain- 
ing 88  institutions  granted  the  balance  of  773  baccalaureate  degrees. 

Both  state  and  private  institutions  were  productive  of  geneticists  at 
the  baccalaureate  level.  Land-grant  institutions  awarded  35.7%  of  the 
baccalaureate  degrees  in  the  present  investigation.  In  Chiscon's  study  of 
the  academic  origin  of  Drosophila  workers,  23%  of  the  baccalaureate 
degrees  were  awarded  by  land-grant  institutions  (2).  In  the  present 
investigation,   land-grant   and   state    colleges   and   universities   together 


372  Indiana  Academy  of  Science 

granted  595  baccalaureates,  58.4%  of  the  total,  while  private  and  denomi- 
national institutions  awarded  36.8%  of  the  total,  or  375  baccalaureates. 
Kiefler  observed  that  the  nation's  liberal  arts  colleges  have  played  an 
important  role  in  producing  scientists  and  have  produced  more  than  half 
the  science  doctorates  in  the  past  (7).  In  the  present  study,  however, 
only  36.8%  of  the  baccalaureates  were  awarded  by  liberal  arts  colleges. 

In  the  top-ten  institutions  granting  baccalaureate  degrees  were  eight 
state  and  two  private  universities  (Table  1).  Concerning  the  productivity 
of  institutions  in  relation  to  the  natural  sciences,  Thistlewaite  stated: 

Natural  science  productivity  is  associated  with  large  freshman  enroll- 
ments, graduate  programs  offering  the  Ph.D.,  public  support,  and 
absence  of  religious  affiliation.  These  characteristics  are  typical  of  the 
state  university,  which  .  .  .  tends  to  be  outstandingly  effective  in 
stimulating  achievement  in  the  natural  sciences.  (9) 

The  present  study  supports  Thistlewaite's  generalization  in  two 
ways:  1)  land-grant  and  state  colleges  and  universities  awarded  58.4% 
of  the  baccalaureates  and  2)  eight  of  the  ten  leading  institutions  grant- 
ing baccalaureates  were  state  universities. 

Comparing  the  ten  leading  baccalaureate  institutions  in  the  present 
investigation  with  the  ten  leading  institutions  in  Chiscon's  study  of 
Drosophila  workers  and  with  Lyon's  study  of  botanists  revealed  that 
many  of  the  institutions  which  appeared  in  the  top-ten  in  this  study  were 
also  in  the  top-ten  in  Chiscon's  and  Lyon's  studies.  California  and  Illinois 
were  among  the  ten  leading  universities  in  all  three  studies.  Harvard 
and  Texas  were  among  the  ten  leading  universities  granting  baccalaure- 
ates to  the  members  of  the  Genetics  Society  of  America  and  also  to 
the  Drosophila  workers  in  Chiscon's  study  (2).  Cornell  University  and 
the  universities  of  Minnesota,  Nebraska,  and  Wisconsin  were  among  the 
ten  leading  institutions  granting  baccalaureates  to  the  members  of  the

study  (8). 

In  the  present  study,  999  of  the  1019  geneticists  completed  doctoral 
degrees;  954  earned  the  Ph.D.  degree.  Ninety- three  institutions  awarded 
these  doctorates.  Among  the  ten  leading  institutions  granting  doctorate 
degrees  were  six  state  and  four  private  universities  (Table  2).  In 
general,  the  top-ten  baccalaureate  institutions  were  also  the  top-ten  doc- 
torate institutions.  However,  Columbia  and  Yale,  which  were  among  the 
ten  leading  doctorate  universities,  replaced  the  universities  of  Nebraska 
and  Illinois,  which  were  among  the  ten  leading  baccalaureate  institutions.

Land-grant  institutions  awarded  38.7%  of  the  geneticists'  doctoral 
degrees.  Land-grant  and  state  institutions  together  granted  605  doctor- 
ates or  60.5%  of  the  total,  while  private  and  denominational  institutions 
awarded  381  doctorates,  or  38.1%  of  the  total. 

Geographic  Origins.  To  reveal  which  areas  of  the  U.S.  were  the 
most  productive  of  geneticists,  the  geneticists  were  divided  according  to 
the  nine  regions  of  the  U.S.  in  which  they  were  born  (Table  3).  These 
nine  regions  were  used  in  Harmon's  1961  study  (4).  The  total  number 
of  geneticists  produced  by  all  the  regions  is  slightly  less  than  the 
number  employed,  because  the  places  of  birth  for  six  of  the  geneticists 
were  not  listed  in  American  Men  of  Science. 

Together  the  Middle  Atlantic  and  East  North  Central  states  pro- 
duced 45.5%  of  the  geneticists.  Indiana  was  the  least  productive  of  the 
five  states  included  in  the  latter  region  (Table  3).  Only  20  of  the  geneti- 
cists included  in  this  investigation  were  born  in  Indiana  and  of  these  six 
retain  their  Indiana  residences.  Thirteen  of  the  20  obtained  baccalaureate 
degrees  from  institutions  in  the  state,  while  only  six  earned  their  doc- 
torates within  the  state.    A  total  of  27  geneticists    (Table  4)    earned

baccalaureate  degrees  from  Indiana  schools.  Indiana  and  Purdue  Univer- 
sities ranked  thirteenth  and  fourteenth,  respectively,  in  the  nation  in 
granting  doctoral  degrees  to  geneticists  in  this  study,  Indiana  having 
granted  27  and  Purdue  23. 

Harmon  and  Soldz'  1960  study  (6)  showed  that  the  regions  producing 
the  greatest  number  of  science  doctorates  are  the  Middle  Atlantic,  East 
North  Central,  and  Pacific.  The  latter,  however,  has  not  been  highly  pro- 
ductive of  geneticists  (Table  3).    Among  the  states  New  York  was  the

most  productive  (173  geneticists)  and  Mississippi  the  least  productive 
(no  geneticists).  Mississippi  is  included  in  the  East  South  Central  states, 
which  generally  have  been  low  producers  of  scientists. 

Comparisons  of  Data  Concerning  Male  and  Female  Geyieticists 

In  Harmon's  study  of  Ph.D.'s  in  the  sciences,  slightly  over  10%  of 
the  doctorate  holders  were  women  (5).  In  the  present  investigation  of 
1019  geneticists,  12.5%  or  127  were  women. 

Thirty-eight  percent  of  the  men  but  only  fifteen  percent  of  the 
women  earned  baccalaureates  at  land-grant  colleges  and  universities.  The 
women,  however,  were  more  frequently  graduated  from  private  colleges 
and  universities  than  were  the  men.  Land-grant  institutions  awarded 
30.6%  of  the  women's  doctoral  degrees  and  39.8%  of  the  men's  doctorates. 
Private  colleges  and  universities  awarded  45.4%  of  the  women's  doctoral 
degrees  and  36.6%  of  the  men's  doctorates.  Institutions  outside  the 
United  States  granted  1.2%  of  the  men's  doctoral  degrees,  but  none  of 
the  women  earned   doctorates  from  foreign  universities. 

A  higher  percentage  of  women  are  employed  by  private  colleges 
and  universities,  while  a  higher  percent  of  the  men  find  employment  in 
state  colleges  and  universities.  Colleges  and  universities  employ  77.2% 
of  the  women  and  78.6%  of  the  men.  In  Harmon's  1965  study  (5)  a 
higher  percentage  of  men  than  women  found  employment  in  business 
and  industry.  Among  the  geneticists,  however,  no  difference  between  the 
sexes  is  apparent  with  6.0%  of  the  men  and  6.3%  of  the  women  finding 
employment  in  business  and  industry. 

In  general,  the  men  completed  the  doctorate  in  fewer  years  following 
completion  of  the  baccalaureate  than  did  the  women.  Five  years  after 
the  baccalaureate,  47.2%  of  the  men  had  earned  the  doctorate;  but  only 
26.5%  of  the  women  had  completed  the  doctoral  requirement.  The  aver- 
age time  beyond  the  baccalaureate  for  the  male  to  complete  the  doctorate 
was  6.7  years,  while  the   121   women  completing  that   degree   required

an  average  of  just  under  9  years.  Only  9.7%  of  the  men  but  20.7% 
of  the  women  earned  doctorates  after  age  34.  None  of  the  121  women 
earned  a  Sc.D.  degree,  but  1.8%  of  the  men  earned  that  degree.  The 
M.D.  degree  was  earned  by  3.0%  of  the  men  and  almost  3.0%  of  the 
women.  The  majority  of  both  sexes  earned  the  Ph.D.  degree.  Certain 
areas  of  research  were  more  attractive  to  men  than  to  women  (Table  5). 
Men  more  frequently  specialized  in  plant  genetics,  statistics,  and  bio- 
physics than  did  the  women;  whereas,  women  more  frequently  entered 
the  fields  of  microbial  and  biochemical  genetics  than  did  the  men.  About 
50%  of  both  men  and  women  have  specialized  in  some  aspect  of  animal 
genetics. 

Conclusions 

The  data  obtained  in  this  study  justify  the  following  conclusions: 

1.  The  baccalaureate  origins  of  the  geneticists  were  more  varied 
than  their  doctoral  origins,  the  baccalaureate  degrees  having  been 
awarded  by  281  different  institutions  and  the  doctorates  having  been 
granted  by  93  institutions. 

2.  Private  colleges  and  universities  produced  over  one-third  of  the 
geneticists,  while  state  and  land-grant  institutions  granted  over  50% 
of  their  baccalaureates  and  over  60%  of  their  doctorate  degrees.  Eight 
of  the  ten  leading  institutions  granting  baccalaureates  were  state  institu- 
tions; six  of  the  ten  leading  doctorate  institutions  were  state-supported. 

3.  Many  of  the  ten  leading  institutions  granting  baccalaureates  to 
the  geneticists  also  were  included  in  the  leading  institutions  granting 
baccalaureates  to  botanists  and  Drosophila  workers.  This  may  be  indica- 
tive that  certain  institutions  are  generally  productive  of  life  scientists. 

4.  The  Middle  Atlantic  and  East  North  Central  states  constituted 
regions  in  the  U.S.  that  were  most  productive  of  geneticists.  Indiana  pro- 
duced only  20  of  the  1019  geneticists  in  this  study. 

5.  At  both  the  baccalaureate  and  doctorate  level,  women  geneticists 
were  more  frequently  graduated  from  private  colleges  and  universities 
than  were  men.  The  men  more  frequently  earned  degrees  from  land- 
grant  colleges  and  universities.  Geneticists  tended  to  find  employment 
in  the  kinds  of  institutions  from  which  they  earned  their  degrees;  a 
higher  percentage  of  women  were  employed  by  private  colleges  and 
universities,  whereas  a  higher  percent  of  the  men  found  employment 
in  state  colleges  and  universities.

Original  Science  Apparatus  Preserved  in 
Science  Museums  and  Universities  in  Free  Europe 

N.  G.  Sprague,  Ball  State  University 

Original  science  apparatus  is  where  you  find  it:  Florence,  Leyden, 
Glasgow,  or  Cambridge.  A  search  during  the  spring  of  1968  for  original 
apparatus  behind  present-day  physics  and  astronomy  led  the  author 
through  many  interesting  by-ways  of  free  Europe. 

Using  World  of  Learning  and  American  Ephemeris  and  Nautical 
Almanac  as  sources  for  addresses,  one  hundred  scientists  and  museum 
directors  and /or  curators  were  contacted  in  fifty  observatories  and 
museums.  All  persons  were  cordial  in  their  response  concerning  a  visit. 
Original  pieces  of  science  apparatus  were  located  in  twenty  museums  in 
fourteen  countries.  The  number  of  items  ranged  from  one  or  two  to  an 
entire  room  dedicated  to  a  single  scientist.  It  was  observed  that  there 
was  twice  as  much  stored  away  as  there  was  on  display.  This  probably 
accounted  for  the  overcrowding  observed  in  most  museums.  Some  pieces 
of  apparatus  were  displayed  in  a  regular  museum,  some  in  the  seminar 
room  of  a  university  department,  and  others  along  corridors. 

In  1657,  Cardinal  Leopoldo  de  'Medici  together  with  his  brother,  the 
Granduke  Ferdinando  II — both  followers  of  Galileo — founded  in  Flor- 
ence the  Accademia  del  Cimento,  the  first  modern  scientific  institute  in 
Europe.  In  the  Museum  of  the  History  of  Science,  situated  in  the  medi- 
eval Castellani  Palace  in  Piazza  dei  Guidici  near  the  Arao  River,  many 
of  the  most  interesting  and  valuable  relics  of  Galileo  and  his  pupils  of 
the  Accademia  del  Cimento  are  preserved. 

Many  scientific  objects  in  the  outer  rooms  tend  to  divert  the  visitor, 
however  one  pushes  forward  to  the  blue  velvet  lined  room  of  Galileo 
Galilei.  There  are  two  of  the  telescopes  with  which  he  studied  the  skies, 
discovering  the  valleys  of  the  moon,  the  phases  of  Venus,  and  four  of 
the  satellites  of  Jupiter;  his  campassec;  pendulum  diagrams  and  weights; 
air  thermometer;  astrolab;  and  publications.  Some  of  these  were  re- 
lated to  his  "swinging  lamp"  and  "leaning  tower"  experimentation  in 
Pisa,  about  fifty  miles  to  the  west. 

Instruments  of  one  of  his  famous  pupils,  Evangelista  Torricelli,  are 
there:  a  metal  case  telescope  and  his  1643  mercury  tube  barometer. 
Several  rooms  are  filled  with  later  dated  telescopes  of  unusual  designs 
and  mountings.  Others  contain  case  after  case  of  astrolabs  and  measur- 
ing devices.  In  the  center  of  one  room  was  a  large  16th  century  armillary 
sphere  made  by  the  Florentine  instrument  maker,  Volpaja.  Elsewhere  in 
the  museum  were  located  a  lens  grinder,  ruling  machine,  and  spectro- 
scope. 

Three  weeks  later  a  large  collection  was  photographed  in  the  Rijks- 
museum  voor  de  Geshiedenis  der  Natuurwelenschappen  at  Leyden,  Hol- 
land. The  name  brings  to  mind  windmills  and  capacitors.  They  had  both.

However,  it  was  also  the  home  territory  of  Huygen,  Leeuwenhoek,  and 
Onnes. 

There,  in  1656,  Christian  Huygens  made  the  important  invention  of 
the  pendulum  clock,  which  had  been  conceived  independently  by  Galileo 
fifteen  years  earlier  but  had  never  been  expanded  to  its  basic  capa- 
bilities. Huygens  also  applied  the  clock  principal  to  a  plate-type  plane- 
tarium. 

Antony  van  Leewenhoek  in  the  1670's  made  the  first  study  of  the 
miniature  water-world  with  single  lens  microscopes.  He  taught  himself 
to  grind  lenses  and  made  microscopes  capable  of  magnifying  up  to  270 
times.  An  entire  room  is  given  over  to  his  microscopes  and  later  im- 
provements in  the  field  of  microscopy. 

From  a  much  later  date  there  is  the  apparatus  of  Heike  Kamerlingh 
Onnes,  the  1913  Nobel  prize  for  physics  winner.  With  it  he  discovered  a 
method  of  liquefying  helium. 

Across  the  English  channel  science  history  was  also  made,  and  many 
pieces  of  apparatus  are  still  preserved.  A  very  fine  collection  from  Lord 
Kelvin  and  James  Joule  was  found  in  the  new  Physics  Building  of  the 
University  of  Glasgow,  Scotland. 

Early  in  life  Lord  Kelvin  became  fascinated  with  the  possibilities 
of  electrical  currents  for  signalling  over  long  distances  and  soon  was 
personally  involved  in  the  company  that  was  trying  to  lay  the  first 
Atlantic  cables.  In  one  display  case  were  many  pieces  of  apparatus 
from  that  association:  a  high  voltage  electrostatic  voltmeter;  the  "cable" 
galvanometer  used  to  receive  the  first  message,  "Europe  and  America 
are  united  by  telegraphic  communication!  Glory  to  God  in  the  Highest 
and  on  earth  peace  and  good  will  to  all  men,"  which  was  sent  by  cable 
under  the  Atlantic  Ocean;  a  Centi-ampere  Balance  with  which  Lord 
Kelvin  originated  the  principle  of  "weighing"  electric  current  by  balanc- 
ing the  attraction  between  sets  of  coils  against  weights;  and  a  Mouse 
Cage  Electric  Motor. 

Kelvin  was  also  noted  for  some  of  his  teaching  devices:  the  French 
horn  which  he  himself  played  in  the  classroom  to  illustrate  problems  in 
acoustics;  a  ballistic  momentum-impulse  firearm;  pitch  glacier  started 
1890;  and  Call  Box  with  its  three  compartments  nick-named  by  his 
students  as  "purgatory,  heaven,  and  not  passed." 

James  Prescott  Joule  carried  out  much  scientific  research  in  his  own 
private  laboratory.  However,  some  of  his  discoveries  were  made  with 
Lord  Kelvin.  It  is  fitting  that  several  pieces  of  his  apparatus  are  also 
included  in  the  collection.  A  Joule  Magnetic  Engine,  an  electric  motor 
made  by  Joule  in  1840-3,  is  one  of  the  earliest  motors  in  existence.  It  was 
undoubtedly  used  in  his  studies  on  eletrical  energy.  A  Joule  Calorimeter 
made  of  brass  was  used  by  Joule  in  the  final  determination  of  the  me- 
chanical equivalent  of  heat. 

In  England  one  would  expect  to  find  science  "originals"  at  Oxford 
and  Cambridge.  Henry  Gwyn  Jeffres  Moseley,  while  a  lecturer  at  Ox- 


380  Indiana  Academy  of  Science 

ford,  proved  the  existence  of  a  simple  relationship  between  the  X-ray 
spectrum  of  an  element  and  its  atomic  number,  thereby  showing  that 
the  properties  of  an  element  are  determined,  not  by  its  atomic  weight, 
but  by  its  atomic  number.  He  thus  provided  a  new  method  of  chemical 
analysis  which  has  since  aided  immeasurably  in  solving  various  out- 
standing problems  of  atomic  structure.  Several  of  his  X-ray  spectrom- 
eters are  located  in  the  Museum  of  the  History  of  Science. 

At  Cavendish  Laboratory,  just  off  of  Free  School  Lane  in  Cambridge, 
are  located  several  items  used  in  their  research  by  many  famous  scien- 
tists of  the  late  19th  century  and  the  beginning  of  the  20th.  Found  there 
on  the  third  floor  in  cases  along  a  hall  are  J.  J.  Thomson's  positive  ray 
apparatus  (complete  parabolae  were  first  recorded  with  this  model); 
Aston's  original  mass  spectrograph  (without  the  magnet);  and  C.  T. 
R.  Wilson's  cloud  chamber,  which  was  used  without  any  major  altera- 
tions for  all  the  photographic  work  he  did. 

The  thinking  which  was  behind  these  originals  is  very  impressive. 
It  is  hoped  that  all  students,  in  future  classes  where  various  pieces  of 
apparatus  will  be  used,  will  recognize  and  be  inspired  by  our  scientific 
heritage. 


A  Half  Century  of  Science  at  Ball  State  University 

Robert  H.  Cooper,  Ball  State  University 

In  October,  1952,  0.  B.  Christy  and  Robert  H.  Cooper  co-authored 
a  paper,  "The  First  Thirty-four  Years  of  Science  at  Ball  State  Teachers 
College,"  which  was  presented  at  the  Fall  meeting  of  the  Indiana 
Academy  of  Science  at  Valparaiso  University.  The  paper  reviewed  a 
few  of  the  professors  who  contributed  much  to  the  development  of 
the  institution  and  a  number  of  graduates  who  have  done  much  in  the 
field  of  science  at  various  locations  in  the  world  and  in  numerous  pro- 
fessions. The  present  paper  reviews  in  some  detail  the  administrative 
and  curricular  science  development  of  Ball  State  and  brings  the  in- 
formation up-to-date. 

The  Administration  Building,  where  science  was  first  taught  on  the 
Ball  State  University  campus,  was  built  in  1898.  The  institution  went 
by  a  number  of  names  up  to  June  17,  1918,  when  it  became  known  as  the 
Indiana  State  Normal  School — Muncie  Branch.  For  some  years  the 
president  of  the  Indiana  State  Normal — Terre  Haute  Branch  also  served 
in  that  capacity  for  both  schools. 

The  professors  who  stand  out  as  setting  up  the  initial  high  standard 
of  training  in  the  fields  of  science  included  Frederick  J.  Breeze,  Pro- 
fessor of  Geography  and  Geology;  Dr.  Otto  B.  Christy,  Professor  of 
Botany  and  Agriculture;  Richard  A.  Gantz,  Professor  of  Physiology  and 
Zoology;  Frank  V.  Graham,  Professor  of  Chemistry  and  Physics;  Harry 
H.  Howick,  Assistant  Professor  of  Mathematics,  Physics,  and  Chemistry. 
These  five  instructors  were  outstanding  teachers  and  the  author  of  this 
paper  had  the  privilege  of  having  classes  with  each  of  them.  Professor 
Graham  in  Chemistry  remained  in  the  institution  until  his  death  in  1944; 
Professor  Howick  in  Physics  remained  in  the  institution  until  his  retire- 
ment in  1956;  and  Dr.  0.  B.  Christy  in  Biology  remained  with  the  insti- 
tution until  his  retirement  in  1950.  Dr.  Christy  is  still  living  and  resides, 
along  with  Mrs.  Christy,  at  the  Teachers  Retirement  Home  (Greenwood 
Village),  Greenwood,  Indiana. 

In  February  1921  the  Indiana  General  Assembly  appropriated  $125,- 
000  to  start  the  work  on  the  Science  Hall.  In  1923  the  State  provided  an 
additional  $128,000  to  complete  and  also  to  equip  the  Science  Building.  In 
the  Fall  of  1923  some  classes  were  held  in  Science  Hall  before  its  entire 
completion.  The  building  was  not  in  full  operation  until  the  summer  of 
1924.  At  that  time  it  had  located  within  it  the  Department  of  Business 
Administration,  as  well  as  English,  Mathematics,  and  Science. 

During  the  Spring  of  1924  a  change  too  place  in  the  college  and  in 
the  science  program  which  helped  many  of  the  teachers  who  were  work- 
ing in  eight-month  schools.  Announcement  was  made  of  a  six-week  Mid- 
Spring  Term  from  May  5  to  June  13,  1924.  The  terminology  Summer 
Quarter  was  now  changed  to  First  Summer  Term  and  Second  Summer 

381

Term.  This  made  it  possible  for  a  student  in  an  eight-month  school  to 
enter  Ball  State  at  the  Mid-Spring  Term  and  continue  with  the  First 
and  Second  Summer  Terms  and  thus  get  in  a  half  year  of  credit. 

On  September  9,  1929,  Burris  Laboratory  School  was  opened.  This 
was  to  be  a  very  important  part  of  Ball  State  for  the  remainder  of  the 
half  century  and  more.  Dr.  Earl  Johnson  started  as  principal  and  be- 
came Professor  of  Education  and  finally  Dean  of  the  College  of  Edu- 
cation when  Ball  State  became  a  university  in  1965. 

In  1930-31  the  course  numbering  changed  to  100's,  200's,  300's  and 
400's.  The  second  digit  in  the  listings  under  the  different  divisions  was 
the  key  to  that  division — thus  2  became  the  number  indicating  the  Divi- 
sion of  Biology,  so  Science  120  was  the  freshman  General  Biology;  3 
indicated  the  Division  of  Agriculture;  4  indicated  the  Division  of  Chemis- 
try; 5  indicated  the  Division  of  Geography  and  Geology;  6  indicated  the 
Division  of  Physics;  and  7  indicated  the  Division  of  Human  Physiology 
and  Hygiene. 

Dr.  Willis  S.  Blatchley,  famous  author-naturalist  of  Indiana,  visited 
Ball  State  Teachers  College,  and  lectured  during  the  early  1930's.  Dr. 
Alfred  Kinsey  came  to  Ball  State  and  lectured  and  conducted  field  study 
with  children  in  Christy  Woods  during  the  1930's.  Both  men  were  very 
skillful  in  field  work  and  were  very  knowledgeable. 

Mr.  Frank  Wallace,  State  Entomologist,  was  a  guest  speaker  and 
adviser  in  the  Science  Department  many  times  through  the  years.  His 
excellent  photography,  his  wholesome  Hoosier  philosophy,  and  his 
sage  advice  were  of  much  value.  His  death  in  May  1968  was  a  real  loss 
to  Indiana. 

Dr.  Charles  Deam,  one  of  Indiana's  most  important  plant  taxono- 
mists,  aided  with  advice  concerning  Christy  Woods  and  other  work  within 
the  Science  Department.  The  numerous  visits  by  the  flora  classes  to  his 
well-labeled  arboretum  at  Bluffton  were  of  inestimable  value.  During 
these  visits  he  gave  much  valuable  information  to  the  Ball  State  stu- 
dents. His  death  occurred  in  1953. 

For  a  number  of  years  the  curriculum  in  Agriculture  was  an  inte- 
gral part  of  the  work  at  Ball  State.  The  institution  was  fortunate  to 
have  a  17-acre  woods  and  arboretum  developed  by  Dr.  Christy,  known 
later  as  Christy  Woods.  More  recently  the  institution  purchased  16  acres 
about  two  miles  from  the  campus  which  became  known  as  Ball  State 
University  Wildlife  Preserve,  and  is  an  area  for  study  and  for  collect- 
ing both  fauna  and  flora.  Christy  Woods  has  become  an  outstanding 
research  and  teaching  laboratory  with  a  sizeable  greenhouse  and  prepa- 
ration facility. 

In  more  recent  years  Ball  State  University  has  offered  curricula  for 
the  Nursing  Degree,  the  Degree  in  Medical  Technology,  the  Pre-medical 
Program,  the  Pre-dental  Program,  the  Pre-engineering  Program,  the 
Pre-veterinary    Program,    and   the    Pre-pharmacy    Program. 

Dr.  Donald  Crooks  joined  the  Biology  staff  in  1929  and  later  became 
a  research  worker  in  the  U.  S.  Department  of  Agriculture,  specializing 


History  op  Science  383 

in  the  research  on  the  virus  of  tobacco.  He  retired  December  15,  1967, 
with  honors.  Dr.  Floy  Hurlbut,  a  geographer,  joined  the  staff  in  1931 
and  was  a  very  outstanding  teacher  in  the  field  of  Geography.  She  re- 
tired from  Ball  State  in  1954.  Dr.  Donald  E.  Miller  joined  the  staff  as  a 
Professor  of  Biology  in  1936  and  has  done  a  fine  piece  of  work  with  the 
Indiana  Academy  of  Science,  with  the  counseling  of  Pre-medic  stu- 
dents, with  his  own  teaching,  and  with  Sigma  Zeta,  national  science 
honorary  organization.  Dr.  Robert  H.  Cooper,  Professor  of  Biology,  joined 
the  staff  in  1936  and  became  Head  of  the  Department  of  Science  after 
Dr.  Christy's  retirement  in  1950.  He  continued  in  this  capacity  until 
1965  when  he  became  Coordinator  of  Sciences  and  Mathematics  until 
his  retirement  in  1968. 

In  1947  Dr.  P.  A.  Wiseman,  with  special  training  in  Organic  Chemis- 
try, joined  the  staff  and  is  at  the  present  time  Chairman  of  the  De- 
partment of  Chemistry  in  the  new  Physical  Science  Building.  Dr.  Jerry 
J.  Nisbet  and  Dr.  George  W.  Welker  joined  the  Science  Department  in 
1950.  With  the  organization  of  separate  departments  Dr.  Nisbet  became 
Chairman  of  the  Department  of  Biology.  Dr.  Welker  has  counseled  in 
Medical  Technology  and  aided  students  in  many  ways.  Malcom  E. 
Hults  joined  the  Ball  State  staff  in  1953  and  has  given  much  time  to 
research  and  to  the  development  of  the  Department  of  Physics,  of 
which  he  is  now  Head.  Dr.  George  F.  Beatty,  a  graduate  of  Ball  State, 
returned  to  his  Alma  Mater  in  1958  as  Professor  of  Geography  and  Geol- 
ogy and  is  presently  Head  of  the  Department  of  Geography  and  Geology 
and  Professor  of  Geography  and  is  located  in  the  new  Physical  Science 
Building  with  the  other  members  of  his  staff.  Dr.  Warren  E.  Schaller 
came  to  Ball  State  University  in  1959  and  has  co-authored  a  college 
health  text  and  has  done  much  toward  organizing  and  reorganizing  the 
certification  of  teachers  of  health  in  the  State  of  Indiana.  He  is  cur- 
rently Chairman  of  the  Department  of  Physiology  and  Health  Science. 

Through  the  years  Ball  State  University  has  moved  from  offering 
the  Two-year  Certificate  for  Teaching  to  the  Four-year  Bachelor's  De- 
gree in  the  many  fields  of  teaching  and  research.  The  Master  of  Arts  in 
Education,  the  Master  of  Arts  and  the  Master  of  Science  Degrees  are 
offered  as  the  beginning  of  the  graduate  work.  In  recent  years  more  ad- 
vanced degrees  have  been  offered  and  at  the  present  time  the  Doctor 
of  Education  Degree  with  specialization  in  Science  Education  and  speci- 
fically a  major  in  the  Department  of  Biology  is  being  offered.  Minors 
for  the  doctoral  degrees  are  available  in  the  other  fields  of  science. 

There  was  a  Physical  Science  Club  devoted  to  the  consideration  of 
physics  and  chemistry  problems  listed  in  the  catalog  in  1937-38.  Later 
there  was  a  Science  Club  to  represent  all  of  the  sciences.  In  1938  the 
Sigma  Zeta  math  and  science  honorary  was  organized  and  has  served 
as  a  fine  stimulus  for  science  research. 

In  September  of  1939,  under  the  authorship  of  Dr.  0.  B.  Christy,  a 
bulletin  was  put  out  entitled  An  Outdoor  Laboratory  at  Ball  State 
Teachers  College.  This  was  a  bulletin  concerning  the  history  and  use  of 
Christy  Woods  and  was  the  first  of  its  kind.  It  was  revised  in  1960.

Listed  in  the  catalog  of  1939-40  is  the  Shrawder  Collection.  Through 
contributions  of  the  George  A.  and  Frances  Ball  Foundation,  the  William 
H.  Shrawder  Collection  of  rocks  and  minerals  was  added  to  the  science 
geology  collection  and  is  still  carefully  maintained  as  one  of  the  finest 
in  this  part  of  the  United  States.  Mr.  Shrawder,  a  resident  of  Indiana, 
was  a  teacher  of  geology  in  Schenley  High  School,  Pittsburgh,  Pennsyl- 


With  the  publication  of  the  1951-53  catalog,  an  offering  was  listed 
as  Science  400,  Science  of  Distant  Areas,  four  or  eight  quarter  hours 
credit.  This  listing  finally  led  to  rather  extensive  field  study  in  various 
parts  of  the  United  States  and  in  other  countries.  The  purpose  of  the 
course  was  to  help  the  student  become  acquainted  within  the  five  weeks' 
time,  with  the  flora  and  fauna,  the  agriculture  and  conservation,  and 
any  unique  science  peculiar  to  the  area.  Beginning  with  the  summer  of 
1956  this  became  a  reality  in  that  a  class  was  organized.  Since  that 
time,  under  Dr.  Robert  Cooper,  five  summer  studies  have  been  offered 
in  the  Northwestern  Rocky  Mountains  areas  of  the  United  States  and 
the  Southwestern  Rockies  of  Canada;  four  summers  of  study  have  been 
spent  in  the  State  of  Alaska,  including  the  Point  Barrow  and  Pribilof 
Island  areas,  two  summers  in  the  State  of  Hawaii,  including  field  work 
in  six  of  the  islands;  and  one  summer  in  the  study  of  countries  around 
the  world,  including  Norway,  Switzerland,  Africa,  India,  Australia,  New 
Zealand,  and  Fijii.  Also,  field  study,  under  Dr.  Forrest  Stevenson,  has 
been  done  in  Jamaica  in  two  different  summers. 

In  1954  Ball  State  Teachers  College,  along  with  Earlham  College, 
started  to  sponsor  the  Eastern  Indiana  Regional  Science  Fair  and  this 
has  been  continued  by  Ball  State  up  to  the  present  time.  Earlham  de- 
cided some  years  ago  to  go  into  a  different  type  of  activity  to  inspire 
young  high  school  students  to  go  into  the  field  of  science.  The  Fair  has 
been  sponsored  by  Dr.  Gerald  E.  Doeden  and  Dr.  George  W.  Welker  of 
Ball  State,  along  with  other  members  of  the  staff,  including  Dr.  Robert 
L.  Shelley,  Dr.  Homer  D.  Paschall  and  Dr.  Leon  Reynolds. 

By  1959  the  requirement  for  the  training  of  elementary  teachers 
had  been  balanced  in  such  a  way  that  there  were  two  courses  required  in 
the  life  sciences,  two  in  the  physical  sciences,  two  in  the  earth  sciences, 
two  in  the  health  sciences,  and  one  methods  course  taught  by  persons 
in  the  Science  Department  who  had  had  experience  in  the  elementary 
school.  This  type  of  program  is  still  in  existence  and  has  proved  very 
successful  for  the  training  of  students  going  out  to  do  elementary 
work  and  including  science  in  their  teaching. 

In  1960  Dr.  Robert  H.  Cooper  was  awarded  the  first  annual  Dr. 
James  A.  McClintock  Award.  The  $500  was  applied  toward  the  publica- 
tion of  a  revision  of  Christy  Woods — Outdoor  Laboratories. 

In  1961  the  Science  Lecture  and  Discussion  Series  was  held  the 
first  week  of  February  and  has  been  conducted  annually  up  to  and  in- 
cluding the  current  year,  1968.  At  least  five  outstanding  scientists  have 
appeared  each  time  on  this  two-day  or  one-day  lecture  series.  Prominent 


History  of  Science  385 

persons  who  have  appeared  include  Nobel  prize  winners  and  others  from 
the  National  Severe  Storms  Forecast  Center,  the  Bell  Telephone  Labora- 
tories of  New  Jersey,  and  the  National  Aeronautics  and  Space  Adminis- 
tration of  Washington,  D.  C.  and  Huntsville,  Alabama.  Speakers  from 
medical  colleges,  from  research  departments  of  various  colleges,  and 
from  industry  have  been  included  in  these  series  over  the  years.  This 
has  proved  very  stimulating  for  students,   staff,  and  the  community. 

In  1962  A  Sigma  Xi  Club  was  organized  by  staff  members  in  the 
Departments  of  Science,  Mathematics,  Psychology,  and  Social  Science 
(Anthropology).  This  club  has  been  continuing  its  meetings  and  will  be 
applying  for  Sigma  Xi  Society  chapter  status  in  1968.  This  has  been  a 
stimulating  addition,  so  far  as  faculty  activity  is  concerned. 

In  1965  a  complete  reorganization  of  the  departments  occurred  with 
the  Science  Department  being  organized  into  a  Department  of  Biology, 
Department  of  Chemistry,  Department  of  Geography  and  Geology,  De- 
partment of  Physics,  and  Department  of  Physiology  and  Health  Science. 
Each  department  has  its  own  department  head  and  offers  graduate  de- 
grees and  curricula  of  various  types.  Physics,  Chemistry,  Mathematics, 
and  Geology  moved  into  the  new  Physical  Science  Building  in  the  summer 
of  1967.  This  five-story  building  was  completed  at  a  cost  of  $4,200,000. 

At  the  present  time  construction  is  progressing  on  the  new  Life 
Science  Building,  which  will  house  the  Departments  of  Biology,  Physiol- 
ogy and  Health  Science,  and  Geography.  The  completion  of  this  five- 
story  building  is  anticipated  late  in  the  school  year  of  1969  or  early 
1970  at  a  cost  of  $5,500,000. 

As  of  1967  additional  staff  members  in  the  different  departments  of 
science  have  made  worthwhile  contributions  to  the  development  of  each 
science  in  the  fields  of  research  and  teaching.  Included  are: 

Biology:  Dr.  Jerry  J.  Nisbet,  Chairman  of  the  Department,  Dr. 
Alice  H.  Bennett,  Dr.  Frank  Bernhardt,  Dr.  William  B.  Crankshaw,  Dr.

Ball  State,  with  its  675  acres,  approximately  50  buildings,  about 
15,000  students,  and  a  faculty  of  over  600,  is  considered  "one  of  the 
emerging  universities."  It  developed  from  a  private  school  to  an  institute, 
to  a  normal  school,  to  a  teachers  college,  and  to  a  university.  From  an 
institution  with  230  students  and  30  faculty  members  it  has  developed 
into  a  university  with  five  colleges — Architecture  and  Planning,  Busi- 
ness, Fine  and  Applied  Arts,  Teachers  College,  and  College  of  Science 
and  Humanities.  The  science  instructional  staffs  now  include  not  only 
full-time  professors  but  also  local  physicians,  local  research  workers 
and  laboratory  technicians  and  registered  nurses  who  may  serve  on  a 
part-time  basis.

ABSTRACTS 

Preliminary  Results  of  a  Muon  Energy  Study.  Robert  Callis  and  Edwin 
Craig,  Ball  State  University. — This  study  was  conducted  in  order  to 
determine  the  energy  of  muon  particles  observable  through  liquid  scin- 
tillation detection  when  muon  travel  was  limited  to  a  short  distance. 
Knowing  the  time  delay  necessary  for  each  path  of  electronic  signal  to 
achieve  coincidence,  and  the  distance  of  muon  flight  between  scintillation 
tanks,  the  muon  velocity  can  be  calculated.  Knowing  the  muon  velocity, 
and  the  mass  as  206  me,  the  energy  of  the  muon  can  be  determined. 

The  coincidence  system  used  in  this  study  included  time  to  height 
conversion  and  had  a  resolving  time  of  20  nanoseconds.  With  the  cali- 
brated nanosecond  delay  module  it  was  possible  to  introduce  delays  in 
increments  of  one  nanosecond.  The  average  muon  velocity  was  calcu- 
lated to  be  2.18  x  108m/sec.  The  energy  corresponding  to  this  velocity 
was  40.5  MeV.  The  probability  of  chance  coincidence  occurring  was  2.76  x 
10~s  based  upon  a  probability  certainty  of  1.00.  The  average  number  of 
chance  coincidences  occurring  in  one  second  was  found  to  be  9.94  x  10-5 
counts/sec. 

Determination  of  Absolute  D*  for  Photovoltaic,  Infra-red  Detectors.  John 
F.  Houlihan,  Shenango  Valley  Campus,  Penn  State  University. — A 
practical  and  accurate  method  of  determining  an  absolute  value  of  D:: 
for  photovoltaic,  infra-red  detectors  is  discussed.  The  D*  performance 
parameter  is  defined  and  is  expressed  in  physically  measurable  quantities. 
The  experimental  set-up  is  shown  and  discussed  briefly.  Also  the  correc- 
tion factors  which  are  necessary  due  to  the  experimental  techniques 
used,  are  considered  in  some  detail  and  practical  methods  of  determining 
them  are  given.  A  Fourier  analysis  of  a  square-wave  pulse-train  is  pre- 
sented in  an  appendix  and  the  affect  of  such  a  wave  train  on  an  rms 
meter  considered  in  detail.  Finally,  several  excellent  reference  sources 
for  infra-red  detector  work  are  listed. 

Possible  Methods  for  Observing  Shadow  Bands  at  the  Next  Solar  Eclipse 
in  North  America.  Roger  D.  Burgess  and  Malcom  Hults,  Ball  State 
University. — Immediately  preceding  and  following  an  eclipse  of  the  sun, 
light  and  dark  bands  are  often  seen  moving  across  the  surface  of  the 
earth.  A  great  deal  more  study  of  these  so-called  Shadow  Bands,  both 
theoretical  and  experimental,  is  needed.  This  paper  reviews  the  history  of 
observations  of  the  bands  and  the  attempts  to  explain  them.  A  report 
of  an  observation  of  the  bands  in  Rio  Grande  do  Sul,  Brazil,  November 
12,  1966,  is  given.  More  advanced  methods  of  visually  observing  the 
bands  are  suggested  and  attempts  to  detect  and  measure  shadow  bands 
electronically  are  reported.  The  presentation  emphasizes  the  importance

of  both  visual  observation  and  electronic  detection  of  shadow  bands  at 
the  next  eclipse  March  7,  1970,  which  is  readily  accessable  to  physicists 
and  astronomers  in  North  America. 

Nuclear  Electric  Quadrupole  Resonance  Analysis  of  Chemical  Bonds  in 
CI35- Containing,  Straight-Chain  Hydrocarbons.  David  E.  Koltenbah, 
Ball  State  University. — The  nuclear  electric  quadrupole  moment  of  nuclei 
of  spin  greater  than  or  equal  to  unity  interacts  with  the  electric  field 
gradient  arising  from  the  molecular  or  crystalline  electric  field  in  the 
environs  of  the  given  nucleus.  The  frequency  of  this  interaction  is  sensi- 
tive to  changes  in  the  surrounding  electron  distribution  arising  from 
an  altered  chemical  structure.  Consequently,  the  nuclear  quadrupole 
resonance  (NQR)  frequency  is  related  to  the  structure  of  the  chemical 
bond,  and  the  study  of  the  shift  of  this  frequency  from  one  member  to 
another  in  a  homologous  group  of  compounds  has  been  employed  as  a 
means  of  studying  chemical  bonds.  Extensive  investigations  are  reported 
in  the  literature  in  which  this  effect  has  been  studied  in  halogenated  ring 
and  halogenated  saturated  straight-chain  compounds.  This  paper  re- 
viewed a  systematic  study  of  NQR  frequencies  of  CI35  in  several  chloro- 
alkenes,  of  which  virtually  no  previous  study  had  been  made.  The  in- 
ductive effect  of  -CI,  -CCIH2,  and  -CH3  substitutents  upon  the  electron 
density  of  the  C-Cl  bonds  was  determined.  The  effects  of  hybridization 
and  7r-bonding  characteristics  were  estimated  by  the  Townes-Dailey 
rules,  and  the  C-Cl  bond  ionicities  were  calculated  and  compared  with 
the  ionicities  of  more  abundantly  studied  chloroalkanes. 

Low  Energy  Elastic  Scattering  of  K-Mesons  off  Protons.  Gerald  P. 
Thomas,  Ball  State  University. — Forty-four  K~  -p  low  momentum  elastic 
scattering  events  between  0  and  250  MeV/c  have  been  found  by  following 
265.12  meters  of  Krmeson  tracks,  backward  from  their  capture  points  in 
nuclear  emulsion.  The  total  scattering  cross-section  is  plotted  as  a  func- 
tion of  kaon  momentum  and  this  is  fitted  with  the  s-wave  zero-effective- 
range  theory  with  the  scattering  lengths  A0= — 1.1  +  0.55i,  Ai  =  — 0.20  + 
0.44  i  for  the  isotopic  spin  T  =  O  and  T  =  1  channel  respectively.  Fur- 
ther evidence  for  s-wave  interaction  is  discussed  through  the  angular 
distribution  in  the  center-of-mass  system  for  the  elastic  events. 


The  Design  and  Construction  of  a  System  for 
Direct  Measurement  of  Atomic  Lifetimes 

Theodore  V.  Blanc, i  Ake  G.  Danemar,-  and  David  E.  Koltenbah 
Department  of  Physics,  Ball  State  University 

Abstract 

The  project  reported  in  this  paper  involved  the  design  and  construction 
of  a  system  to  directly  measure  atomic  lifetimes,  and  follows  the  technique 
employed  by  Jules  Klose  of  the  National  Bureau  of  Standards.  A  low  energy 
10  to  3  0  eV,  20  0  nsec-duration,  10  kHz  square  wave  electron  excitation  pulse 
was  used  to  excite  a  gas  at  a  pressure  of  1  X  10-*  Torr.  The  visible  emission 
spectrum  was  observed  by  a  photomultiplier  through  a  grating  spectrometer 
which  permitted  the  selection  of  the  desired  spectral  line  or  energy  level 
transition.  Employing  delayed  coincidence  techniques  familiar  in  nuclear 
physics,  the  square  excitation  pulse  and  the  ensuing  photomultiplier  pulse 
were  fed  into  a  time-to-pulse  height  analyzer  whose  output  would  display 
the  decay  of  the  emission  intensity  as  a  function  of  the  time  for  relaxation 
of  the  atomic  systems.  The  project  was  completed  to  the  construction  of 
the  time-to-pulse  height  converter  and  promises  to  be  useful  in  obtaining 
data  on  atomic  lifetimes. 

Introduction 

This  project  was  the  first  study  by  the  Department  of  Physics  at 
Ball  State  University  in  the  measurement  of  atomic  lifetimes.  For  this 
initial  work  the  project  was  divided  into  two  segments.  The  theoretical 
computations  and  calculations  comprised  the  M.S.  thesis  work  by  Mr. 
Danemar  (4),  while  the  actual  design  and  construction  of  the  system 
comprised  the  M.S.  thesis  work  of  Mr.  Blanc  (2).  This  paper  is  essentially 
a  synopsis  of  the  latter  thesis. 

The  purpose  of  the  project  was  to  design  and  construct  a  system  cap- 
able of  measuring  the  rate  of  decay  of  excited  atomic  energy  levels  in 
neutral  atoms.  The  atomic  excitation  was  achieved  by  bombarding  a  gas 
with  an  electron  beam  of  sufficiently  low  energy  so  as  to  obtain  excita- 
tion of  neutral  atoms  rather  than  ionization.  A  short  square  wave  pulse 
of  low  energy  electrons  was  used  as  the  primary  beam.  The  measurement 
of  the  decay  time  of  the  subsequent  atomic  relaxation  after  the  pulse  was 
made  by  observation  of  the  decay  time  of  the  intensity  of  the  invisible 
radiation  emitted  by  the  gas  as  detected  by  a  grating  spectrometer.  The 
desired  spectral  line  was  selected  from  the  spectrometer  and  the  emitted 
photons  received  by  a  photomultiplier.  By  analysis  of  the  delayed  coinci- 
dence between  the  detected  photomultiplier  pulses  and  the  primary  elec- 
tron pulses,  the  decay  of  the  excited  state  could  be  determined. 

History 

The  method  of  delayed  coincidence  in  photomultiplier  scintillation 
counting  in  nuclear  physics  was  first  applied  to  direct  measurement  of

atomic  lifetimes  by  Heron,  McWhirter,  and  Rhoderick  (6)  about  1954  at 
the  University  of  Glasgow.  They  sought  to  develop  an  accurate  and 
direct  method  of  measuring  atomic  lifetimes  capable  of  determining 
whether  or  not  the  decay  was  of  an  exponential  form.  The  technique  was 
further  developed  by  Bennett,  Javan,  and  Ballik  (1)  in  1960  at  the  Bell 
Telephone  Laboratories  by  using  a  multichannel  pulse-height  analyzer 
in  conjunction  with  a  pulse  time-to-height  converter.  This  method  proved 
to  be  both  enormously  faster  and  stabler  than  the  single-channel  tech- 
nique employed  by  Heron,  et  al  (6).  Later  this  technique  was  employed  in 
1964  by  Holzberlein  (7,  5)  at  the  University  of  Oklahoma,  as  well  as 
by  Pendleton  and  Hughes  (10)  at  the  University  of  Arkansas,  to  measure 
the  lifetime  of  helium.  The  same  technique  was  employed  by  Klose  (8,  9) 
at  the  National  Bureau  of  Standards  to  study  neon  in  1965  and  argon 
in  1967.  Wolff  and  Davis  (13)  at  the  University  of  California  used  a  laser 
excitation  system  to  study  cesium  and  sodium  in  1967. 

Project  Rationale 

The  project  was  appealing  to  the  authors  for  a  number  of  reasons. 
First,  up  to  the  time  of  the  initiation  of  the  project  there  had  been  only 
five  elements  known  to  have  been  in  some  part  studied — helium,  neon, 
argon,  cesium,  and  sodium.  Thus  there  existed  a  need  to  extend  knowl- 
edge to  other  elements  and  to  attempt  to  expand  the  state  of  the  art. 
Second,  the  field  was  relatively  new  and  unpopulated.  With  the  develop- 
ment of  current  electronics  a  successful  technique  had  been  acquired, 
but  insofar  as  could  be  determined  by  the  authors  it  had  been  success-

fully  employed  by  only  four  other  research  groups.  Lastly,  the  equipment 
that  would  be  required  for  the  project  for  the  most  part  consisted  of 
multi-purpose  equipment  of  relatively  moderate  cost  available  at  most 
smaller  universities. 

Experimental  Method  and  Apparatus 

It  is  essentially  after  the  method  and  technique  of  Dr.  Jules  Klose 
of  the  National  Bureau  of  Standards  that  this  project  was  patterned. 
A  block  diagram  of  the  system  used  by  the  authors  is  given  in  Figure  1. 
The  source  of  excitation  was  a  specially  designed  low  pressure  gas  excita- 
tion tube  which  employed  a  low  energy  electron  gun.  A  square  wave  sig- 
nal from  a  pulse  generator  was  applied  to  the  control  grid  of  the  electron 
gun  so  as  to  produce  a  square  electron  excitation  pulse  in  the  gas  under 
study  in  the  tube.  The  spectral  emission  of  the  excited  gas  was  separated 
into  its  components  by  a  grating  spectroscope.  The  particular  energy  level 
transition  or  spectral  line  to  be  studied  was  then  isolated,  detected  by 
a  photomultiplier,  and  subsequently  amplified.  The  same  square  wave 
signal  from  the  generator  was  also  used  to  "start"  a  time-to-pulse-height 
converter.  The  pulse  from  the  photomultiplier  was  used  to  "stop"  the 
time-to-pulse-height  converter.  The  function  of  the  converter  was  to 
feed  a  voltage  pulse  proportional  to  the  time  interval  between  the 
"start"  and  "stop"  into  a  multichannel  pulse  height  analyzer.  Thus  the 
pulse  height  analyzer  displayed  the  emission  intensity  on  the  ordinate 
and  the  emission  life  time  on  the  abscissa. 

The  entire  system  can  be  broken  down  into  four  basic  sections:  1) 
the  vacuum  or  low  pressure  gas  system,  2)  the  spectrograph,  3)  the  elec- 
tronics, and  4)  the  excitation  tube.

The  vacuum  or  low  pressure  gas  system  was  constructed  entirely  of 
glass,  including  a  Delmar  DS-7050-1  glass  mercury  diffusion  pump  which 
was  fused  directly  into  the  system  via  a  liquid  nitrogen  cold  trap.  The 
gas  pressure  in  the  excitation  tube  was  operated  at  approximately 
1  X  10"*  Torr  or  O.lfx.  Since  the  system  was  originally  designed  with  a 
McLeod  pressure  gauge  fused  directly  into  the  system  and  since  the 
gauge  was  found  to  be  a  large  source  of  mercury  contamination,  it  was 
decided  to  study  first  the  atomic  lifetimes  of  mercury. 

The  spectograph  system  consisted  merely  of  a  slightly  modified  large 
Cenco  Model  87102  grating  spectograph  with  a  dispersion  of  16  A /mm. 

The  electronics  system  consisted  of  an  HP-214A  square  wave  pulse 
generator,  an  RCA-6655A  photomultiplier  and  Victoreen  PVS-C  pre- 
amplifier, a  time-to-pulse  height  converter  (3),  a  Victoreen  PIP-400A 
pulse-height  analyzer,  and  an  excitation  tube  control  system.  The  last 
system,  which  is  depicted  diagrammatically  in  Figure  2,  consisted  of  a 
series  of  meters  and  power  supplies  to  enable  the  operator  to  have 
complete  control  and  monitoring  capabilities  over  the  excitation  tube. 

Lastly,  the  excitation  tube — the  very  heart  of  the  project — proved  to 
be  one  of  the  most  difficult  parts  to  design  and  construct.  The  excitation 
technique  employed  by  Klose  (8,  9)  was  basically  designed  by  Simpson  and 
Kuyatt  (12)  at  the  National  Bureau  of  Standards  in  which,  by  using  a 
multistage  device,  electrons  were  first  drawn  from  the  cathode  by  a  high 
potential  of  the  order  300  V  and  then  decelerated  to  obtain  a  beam  of  the 
desired  energy  range  in  the  order  of  10  to  30  eV.  This  design  was  suc- 
cessfully used  by  Klose  in  his  studies  but  was  found  by  the  authors  to  be 
impractical  to  construct  due  to  the  lack  of  sufficiently  sophisticated 
machining  facilities.  Thus  it  was  decided  to  adapt  a  presently  existing 
production  TV  electron  gun  to  the  above  technique.  A  diagram  of  the 
authors'  electron  gun  appears  in  Figure  3.  The  electron  guns  used  in  tele-

vision  picture  tubes  are  designed  to  operate  at  potentials  of  the  order  of 
500  to  5000V.  Use  was  made  of  an  RCA  19GWP22  color  television  gun 
(11)  in  which  the  operating  potentials  on  each  of  the  gun  elements  were 
proportionately  scaled  down  to  produce  an  electron  beam  energy  in  the 
10  to  30  eV  range.  This  gun  system  had  two  advantages — it  was  designed 
to  operate  at  comparatively  low  potentials  and,  since  it  was  a  color  picture 
tube  gun  system,  it  actually  consisted  of  three  guns.  Due  to  the  fact  that 
the  gun  was  to  be  operated  at  relatively  low  potentials,  the  high  potential 
grid  4  and  magnetic  shield  were  removed  from  the  gun  assembly  leaving 
a  three-grid  electron  gun.  This  had  an  advantage  because  the  three  guns 
could  be  operated  singly,  so  that  if  one  gun  burned  out  it  was  possible  to 
change  to  another  gun  by  external  switching  without  opening  the  tube. 
The  collector  was  constructed  out  of  stainless  steel  and  formed  into  a 
"cup"  shape  to  minimize  the  mechanical  recoil  of  the  low  energy  electrons 
back  into  the  excitation  viewing  area. 

The  excitation  tube  functioned  sufficiently  well  for  obtaining  some 
initial  spectrograms,  but  was  not  as  stable  as  desired  because  of  the 
existence  of  a  space  charge  in  the  viewing  area  arising  from  recoil  elec- 
trons from  the  anode.  A  fine  mesh  suppressor  grid  at  the  anode  potential 
should  eliminate  this  annoyance  and  allow  the  tube  to  be  used  for  atomic 
lifetime  measurements.

Hookeriaceae  Species  and  Distribution  in  South  America 

Winona  H.  Welch,  DePauw  University 

Abstract 

This  paper  is  the  second  in  the  series  on  the  distribution  of  the 
Hookeriaceae  in  the  world.  The  first  and  second  studies  pertain,  especially, 
to  North,  Central,  and  South  America,  and  to  the  West  Indies.  Apparently 
the  center  of  distribution  is  in  northern  South  America,  particularly  in  the 
NW  portion  of  the  continent.  The  greatest  endemism  occurs  in  northern 
South  America.  North  America  and  southern  South  America  have  the 
smallest  number  of  species  and  endemics,  the  former  having  the  least. 
There  is  evidence  that  the  Hookeriaceae  is  chiefly  a  tropical  family,  in  the 
Americas,  although  species  occur  from  Alaska  to  the  southern  tip  of  South 
America.  East-West  as  well  as  North-South  distribution  are  shown  by 
species  of  the  Hookeriaceae.  Hookeria  acutifolia  occurs  in  Hawaii,  Canada, 
United  States,  Mexico,  Central  America,  South  America,  West  Indies,  and 
Asia.  Other  species  occur  in  South  America,  Australia,  Tasmania,  New 
Zealand,  and  on  islands  near  South  Africa. 

This  paper  is  the  second  in  the  series  on  the  distribution  of  the 
Hookeriaceae,  based  largely  upon  epithets  and  distribution  areas  cited  in 
Index  Muscorum.  It  is  assumed  that  the  introductory  pages  of  the  first 
paper   (9)   will  be  reviewed  before  reading  this  report. 

The  following  islands  have  been  included  with  South  America: 
Hermite,  Falkland,  Galapagos,  Trinidad,  and  Tobago.  The  area  is  that  of 
the  Index  Muscorum. 

For  reference,  the  areas  in  the  first  paper  are  repeated:  America  1. 
North  America  (Canada,  United  States,  Mexico),  Greenland,  Aleutian 
Islands,  Bermudas;  America  2.  Central  America  and  Cocos  Island;  Amer- 
ica 3.  West  Indian  Islands  (Greater  and  Lesser  Antilles,  Bahamas)  except 
Trinidad  and  Tobago.  The  three  distribution  divisions  of  South  America 
numerically  follow  those  of  North  and  Central  America:  America  4. 
Venezuela,  Colombia,  Peru,  Bolivia,  Ecuador,  Galapagos  Islands;  America 
5.  Brazil,  Paraguay,  Guiana,  Trinidad,  Tobago;  and  America  6.  Chile, 
Argentina,     Uruguay,  Falkland  Islands,  and  Hermite  Island. 

As  assumed  in  the  beginning  of  this  project,  as  monographic  work 
progresses  in  the  family  and  as  collectors  publish  their  papers  on  new 
records  of  species,  often  extending  the  distribution  range,  changes  are 
necessary  to  keep  the  information  up-to-date.  Differences  since  the  first 
paper  (9)  follow.

Three  genera,  Callicostellopsis,  Helicoblepharum,  and  Stenodesmus, 
occur  in  South  America,  only.  Callicostellopsis  is  a  genus  composed  of 
one  species,  meridiensis,  which  has  been  recorded  only  in  NW  South 
America.  The  genus,  Helicoblepharum,  consists  of  four  species,  all  occur- 
ring in  northern  South  America,  one  in  the  NE  and  three  in  the  NW. 
Two  species,  latifolius  and  tenuicuspis,  comprise  the  genus,  Stenodesmus, 
and  are  known  only  from  NW  South  America. 

Two  genera,  Amblytropis  and  Philophyllum,  are  chiefly,  but  not 
totally,  South  American  genera.  One  of  the  five  species  of  Amblytropis, 
A.  denticulata,  is  endemic  in  the  West  Indies.  The  other  four  species, 
A.  gemmacea,  A.  hispidula,  A.  ovata,  and  A.  setosa,  have  been  reported 
only  from  NW  South  America.  The  genus,  Philophyllum,  is  composed  of 
four  species,  all  of  which  occur  in  NE  South  America.  One  species, 
P.  tenuifolium,  has  a  more  general  distribution,  occurring  in  Central 
America  and  northern  South  America. 

In  the  lists  of  Hookeriaceae  in  Am  4,  5,  6,  the  asterisk  indicates  the 
endemic  species,  varieties,  and  forms.  These  plants  presently  are  not 
known  to  occur  in  geographical  areas  other  than  the  ones  cited.  The 
species  of  additional  areas  follow. 

Steere  (4)  stated  that  many  species  of  mosses  of  the  eastern  slopes 
of  the  Andes  and  the  headwaters  of  the  Amazon  extend  from  eastern 
Peru  to  the  West  Indies,  and  that  the  Andean  highlands  of  the  sierra  are 
much  wetter  in  the  north  and  are  most  closely  related  to  the  wet  montane 
and  alpine  forests  of  Colombia  and  Central  America.  Steere  also  points 
to  the  relationship  between  the  genera  of  Ecuador,  Peru,  and  Bolivia,  and 
those  of  Mexico. 

In  the  distribution  patterns  of  the  Hookeriaceae  species,  the  following 
have  been  noted  by  the  author. 

Callicostella  pallida  has  been  recorded  from  northern  South  America, 
Central  America,  Mexico,  southern  United  States,  and  the  West  Indies. 

Lepidopilum  polytrichoides  occurs  throughout  South  America,  in 
Central  America,  Mexico,  Florida,  and  the  West  Indies. 

Lepidopilum  scabrisetum  has  been  reported  from  the  three  distribu- 
tion areas  of  South  America,  from  Central  America,  Mexico,  and  the 
West  Indies.

Adelothecium  bogotense,  Crossomitrium  patrisiae,  Cyclodictyon 
albicans,  Hookeriopsis  cruegeriana,  Isodrepanium  lentulum,  and 
Lepidopilum  radicale  have  been  recorded  from  northern  South  America, 
Central  America,  Mexico,  and  the  West  Indies. 

Cyclodictyon  roridum,  Daltonia  longifolia,  and  Lepidopilum  torti- 
folium  occur  in  NW  South  America,  Central  America,  Mexico,  and  the 
West  Indies. 

Daltonia  gracilis  is  known  from  three  distribution  areas  of  South 
America,  Central  America,  and  from  Mexico. 

The  distribution  ranges  of  Cyclodictyon  rubrisetum,  Lepidopilum 
brevipes,  and  L.  carneum  follow  the  Cordilleran  pattern,  in  NW  South 
America,  Central  America,  and  Mexico. 

Callicostella  scabriseta  and  Hookeriopsis  incurva  may  be  collected 
throughout  South  America,  in  Central  America,  and  in  the  West  Indies.

Central  America,  and  the  West  Indies:  Cyclodictyon  cuspidatum, 
Daltonia  stenophylla,  Hemiragis  aurea,  and  Hookeriopsis  undata. 

Hookeriopsis  falcata  and  Leskeodon  andicola  occur  in  NW  South 
America,  Central  America,  and  the  West  Indies. 

The  distribution  range  for  Callicostella  depressa,  Hookeriopsis 
acicularis,  and  Leskeodon  cubensis  is  NE  South  America,  West  Indies, 
and  Central  America. 

Hookeriopsis  crispa,  H.  variabilis,  Hypnella  pilifera,  Neohypnella 
chrysophyllopodia,  Philophyllum  tenuifolium,  and  Thamniopsis  pendula

ambiguum,    L.    biductulosum,    L.    nanothecium,    L.    sub  fie  xi folium,    and 
Thamniopsis  killipii. 

Three  South  American  species  are  known  only  from  distribution  areas 
four  and  six:  Callicostella  scabriuscula,  Daltonia  trachyodonta,  Hookeria 
lorentzii,  H.  uliginosa,  Lepidopilum  erectiusculum,  and  Pterygophyllum 
rigidum. 

Lepidopilum  plebejum  has  been  collected  in  S  and  NE  South 
America. 

Hookeria  acutifolia  has  been  recorded  from  islands  of  the  Pacific  or 
in  Oceania  (Hawaii),  in  Canada  (British  Columbia),  the  United  States 
(from  Washington  to  Alabama,  Georgia,  and  Connecticut),  in  Mexico, 
Central  America  (Guatemala,  Costa  Rica),  South  America  (Ecuador, 
Bolivia,  Brazil),  West  Indies  (Cuba,  Jamaica,  Haiti,  Porto  Rico,  Guade- 
loupe), and  in  Asia  (Japan,  India,  Nepal,  Ceylon,  North  and  Central 
Vietnam,  Sumatra,  Java).  It  is  evident  that  this  species  shows  an  exten- 
sive north  and  south  as  well  as  east  and  west  distribution  range. 
However,  H.  acutifolia  may  not  be  regarded  as  a  cosmopolitan  species. 

The  following  species  have  east-west  or  lateral  distribution  instead  of 
north-south  or  vertical.  The  method  of  distribution  may  be  clarified  as 
additional  localities  are  discovered.  Distichophyllum  assimile  and 
Pterygophyllum  obscurum  have  been  collected  in  southern  South  America, 
in  Australia,  and  Tasmania. 

Distichophyllum  rotundifolium,  Eriopus  apiculatus,  Pterygophyllum 
dentatum,  Sauloma  tenella,  and  S.  tenella  f.  propagulifera  have  been 
reported  from  southern  South  America,  Australia,  Tasmania,  and  New 
Zealand. 

Eriopus  flexicollis  has  been  collected  in  southern  South  America  and 
New  Zealand. 

Eriopus  cristatus  is  known  from  southern  South  America,  Oceania, 
Australia,  Tasmania,  New  Zealand,  Madagascar,  Maritius,  and  Reunion. 

It  would  seem  that  this  east-west  distribution  has  been  due  to  conti- 
nental drift,  using  Wegener's  explanation  (6);  that  is  "to  the  process  of 
relative  movements  among  continents."  Wegener  (5)  assumed  that  all 
the  continents  had  been  united,  comprising  adjacent  parts  of  a  large 
supercontinent.  The  latter  broke  up  into  the  present  continents  which 
drifted  apart.  Since  fossil  remains  of  identical  animals  and  plants  have 
been  found  in  the  widely  separate  continents  of  Africa  and  South 
America,  it  seems  plausible  that  there  can  be  like  species  of  mosses  living 
today  on  these  distant  continents.1 

Creer  (2)  proposed  that  the  southern  hemisphere  supercontinent 
started  to  break  up  about  150-200  million  years  ago,  to  form  the  conti- 
nents of  South  America,  Africa,  Australia,  and  Antarctica;  and  the 
subcontinents  of  India  and  Madagascar.

Dietz  (3)  states  that  "most  paleontologists  claim  that  it  is  easier  to 
explain  the  occurrence  of  similar  species  on  continents  widely  separated 
by  the  ocean  on  the  basis  of  transfer  of  living  creatures  by  rafting  on 
flotsam,  by  easy  moves  along  ancient  island  chains,  or  by  long  subsided 
land  bridges,  rather  than  by  continental  drift."  The  paleontologists  also 
explain  that  a  "supposedly  simpler  method  than  continental  drift,  would 
be  dispersion  of  living  creatures  over  isthmian  links  (like  the  Isthmus  of 
Panama  today),  which  included  narrow  land  bridges  between  Africa  and 
South  America,  for  instance." 

Axelrod  (1)  reviewed  the  paleontological  evidence  for  the  late  Paleo- 
zoic and  Mesozoic,  and  concluded  that  the  fossil  floras  suggested  stable, 
not  drifting  continents.  One  of  his  conclusions  was  that  the  vegetation- 
climatic  zones  display  a  symmetrical  arrangement  from  northern  to 
southern  hemispheres  consistent  with  continental  stability. 

Whichever  theory  one  accepts,  the  evidence  of  these  species  of  the 
Hookeriaceae  on  such  distant  land  bodies  is  a  challenge  to  a  bryologist.

A  summary  of  the  Hookeriaceae  species,  varieties,  and  forms,  and 
the  endemics,  based  upon  data  presently  known,  in  North,  Central,  and 
South  America  follows:  Am  1:  36  species,  8  of  which  are  endemic;  Am 
2:  96  species,  39  of  which  are  endemic;  Am  3:  107  species,  54  of  which 
are  endemic;  Am  4:  255  species,  173  of  which  are  endemic;  Am  5:  192 
species,  137  of  which  are  endemic;  Am  6:  47  species,  23  of  which  are 
endemic.  The  greatest  endemism  occurs  in  northern  South  America  as 
shown  by  a  total  of  310  endemics.  The  largest  number  of  species  and 
endemics  occurs  in  Am  4  or  northwestern  portion  of  South  America  and 
decreases  to  the  east,  north,  and  south.    North  America  and  southern 


Plant  Taxonomy  405 

South  America  have  the  smallest  number  of  species  and  endemics,  the 
former  having  the  least.  It  is  also  evident  that  the  family  Hookeriaceae 
is  chiefly  a  family  of  tropical  mosses  in  the  Americas,  although  species 
occur  from  Alaska  to  the  southern  tip  of  South  America,  Hermite  Island, 
and  the  Falkland  Islands.

Some  Late  Glacial  Charophytes  Compared  to  Modern  Species

Abstract 

Some  Date  Glacial  Charophytes  Compared  to  Modern  Species.  Fay 
Kenoyer  Daily,  Butler  University. — Fossil  fructifications  from  New  York  pro- 
vided by  Norton  G.  Miller  were  referred  to  the  moden  taxa,  Chara  sejuncta 
and  Tolypella  glowierata.  This  Tolypella  displayed  a  triply-segmented  basal 
plate  on  the  oospore  while  a  Tolypella  (undoubtedly  T.  prolifera)  reported 
in  an  earlier  study  had  an  undivided  basal  plate.  In  view  of  these  findings 
and  the  conflicting  literature  on  this  subject,  some  selected  modern  speci- 
mens were  studied.  It  was  found  that  Tolypellas  of  the  Section  Conoideae  to 
which  T.  prolifera  belongs  had  an  undivided  basal  plate  similar  to  that  in 
the  Chareae.  Members  of  the  Section  Allantoideae  represented  by  T.  glom- 
erata  had  doubly  or  triply-segmented  basal  plates  as  in  Nitella.  For  the 
first  time  in  a  Tolypella,  some  well-developed,  hard  limeshells  were  dis- 
covered in  a  collection  of  Tolypella  prolifera  from  Indiana.  Calcium  de- 
posits inside  the  spiral  cells  were  also  found  in  oogonia  of  other  members  of 
the  Conoideae.  No  similar  deposits  were  found  in  the  Allantoideae  or  in 
Nitella.  Descriptions  and  illustrations  as  well  as  a  consideration  of  the 
evolutionary  significance  of  these  findings  are  given. 

Introduction 

In  1961,  some  fossil  charophytes  were  reported  from  New  York  (5). 
Among  them  were  charophytes  referred  to  the  recent  species,  Chara  se- 
juncta and  Tolypella  (probably  T.  prolifera) . 

The  Tolypella  oospore  (Text-figure  1)  was  damaged,  but  its  un- 
mistakable characteristics  caused  no  hesitation  about  referral  to  that 
genus.  However,  it  was  perplexing  that  the  specimen  had  an  undivided

basal  plate  (Text-figure  1,  no,  2).  Grambast  (6)  described  the  basal 
plate  of  a  fossil  Tolypella  from  the  Tertiary  of  the  Paris  Basin  as  having 
three  segments  similar  to  that  in  Nitella.  Horn  af  Rantzien  (7)  in  1959 
questioned  the  persistence  of  sterile  oogonial  cells  in  Nitella  and 
Tolypella  to  produce  the  three-parted  plate.  He  reported  not  having 
seen  any  although  some  of  his  photographs  suggest  their  presence.  In

charophyte  fructifications  from  the  Tertiary  of  the  Paris  basin.  He 
explained  that  Horn  af  Rantzien  had  examined  them  and  "has  seen 
that  there  is  considerable  similarity  between  the  triply-segmented  basal 
plate  of  these  fructifications  and  the  three  oogonial  cells  demonstrated 
to  occur  in  Nitella."  Since  both  genera  belong  to  the  Nitelloideae,  they 
were  expected  to  be  similar  in  this  respect. 

Recently,  more  fossil  charophyte  specimens  collected  in  New  York 
were  made  available  for  study.  Mr.  Norton  G.  Milleri  sent  four  vials 
which  contained  oospores  from  the  basal  marl  at  Houghton  Bog,  several 
miles  north  of  Springville,  Erie  Co.,  New  York.  It  is  11,880±  730  years 
B.  P.  (Norton  G.  Miller  communication).  The  oospores  had  been  treated 
with  hydrochloric  acid.  Some  untreated  material  from  this  site  was 
also  obtained.  This  had  been  collected  with  a  piston  sampler.  Oospores 
and  lime-shells  of  Chara  sejuncta  A.  Br.  were  obtained  from  that  site. 
(For  a  description  and  illustration  of  this  species  see  Daily,  5) 

Another  vial  contained  oospores  picked  from  untreated  organic 
debris  collected  ca.  ten  feet  beneath  a  gravel  deposit  near  Lockport, 
N.  Y.  This  material  was  deposited  near  the  shore  of  Lake  Iroquois  and 
has  been  dated  at  12,000±  400  years  B.  P.  (1).  Chara  sejuncta  A. 
Br.  and  Tolypella  glomerate  Desv.  in  Lois,  were  found  in  that  deposit. 
(A  description  and  illustrations  can  be  found  in  the  Systematic  Section 
for  T.  glomerata).  Pollen  found  in  the  sediments  imply  that  a  spruce 
forest  was  dominant  during  the  time  the  charophytes  were  being  de- 
posited. (Norton  G.  Miller  communication). 

One  of  the  interesting  things  about  the  T.  glomerata  oospores  was 
that  the  basal  plates  were  triply-segmented  instead  of  undivided  as  in 
the  T.  prolifera  oospores  from  the  New  York  deposits.  (See  also  Plate 
1,  figs.  8-10,  T.  intricata,  for  an  undivided  basal  plate.)  It  was  then 
recognized  that  these  two  species  represented  the  two  sections  of  Toly- 
pella. T.  prolifera  belongs  to  the  Section  Conoideae  with  short,  conical 
and  acute  ultimate  cells  of  the  branchlet  rays,  spiral  cells  not  swelling 
at  the  apex  and  persistent  coronula.  T.  glomerta  belongs  to  the  Allan- 
toideae  with  ultimate  cells  of  the  branchlet  rays  elongate,  spiral  cells 
swelling  at  the  apex  and  coronula  deciduous. 

Therefore,  it  was  decided  to  examine  some  herbarium  specimens  of 
extant  species  representing  the  two  sections  of  Tolypella  to  see  if  the 
basal  plate  in  the  Allantoideae  was  consistently  segmented  and  in  the 
Conoideae  undivided.  The  basal  plates  were  best  demonstrated  by 
transmitted  light  and  high  power.  The  integuments  were  removed  from 
the  basal  portion  of  the  oospore  which  had  been  hand  sectioned  and 
flattened  on  the  slide. 

Results  obtained  with  selected  specimens  are  given  in  Table  1.  They 
show  that  species  of  Tolypella  belonging  to  the  Conoideae  do  have 
oospores  with  a  consistently  undivided  basal  plate  (Plate  1,  Fig.  10). 
Members  of  the  Allantoideae  may  have  oospores  with  a  two-  or  three- 
segmented  basal  plate  (Plate  1,  Figs.  12,  14,  15).  Furthermore,  hard 
lime-shells  were  found  in   Tolypella  prolifera    (Plate   1,   Figs.   1-4),   T.

intricata  (Plate  1,  Figs.  5-7),  and  T.  fimbriata  (Table  1,  nos.  12,  9,  & 
11  respectively),  which  belong  to  the  Conoideae.  However,  none  of  the 
specimens  examined  belonging  to  the  Allantoideae  produced  lime-shells. 
Hard  lime-shells  in  the  Conoideae  have  apparently  gone  unnoticed  before. 
Various  authors  have  described  the  accretion  of  crystals  on  the  ex- 
terior of  Tolypella  oogonia  or  internal  discrete  crystals  on  the  oospores 
beneath  the  integuments  in  damaged  specimens,  but  hard  lime-shells  in 
undamaged  specimens  were  thought  not  to  exist. 

A  description  and  illustration  of  the  lime-shell  of  T.  prolifera  from 
Indiana  is  included  in  the  systematic  part  of  this  paper.  Calcification 
developes  inside  undamaged  spiral  cells  of  the  oogonium  beginning  as 
discrete  crystals  on  the  adaxial  wall,  but  finally  consolidating  and 
filling  the  slightly  convex  spirals  producing  an  opaque,  smooth,  hard 
lime-shell  without  concentric  lamination.  A  suggestion  of  the  original 
discrete  crystalline  consistency  remains  even  after  the  crystals  consoli- 
date because  of  a  difference  in  opacity  between  the  crystals  and  their 
juncture. 

Discussion 

While  studying  morphological  development  in  extant  Characeae, 
Sawa  (10)  found  two-  and  three-parted  basal  plates  in  Nitella,  but  ob- 
served only  undivided  basal  plates  in  Tolypella.  However,  he  stated, 
"there  is  a  separate  group  of  Tolypella-like  plants  with  Nitella-like 
oogonia  and  oospores  some  of  which  might  have  been  identified  as  vari- 
ous species  of  Tolypella  in  the  past."  That  these  were  stated  to  be 
laterally  compressed  is  a  misprint  (personal  communication).  They 
were  not  laterally  compressed  or  in  other  words,  they  were  terete.  They 
also  had  oospores  with  a  three-parted  base  similar  to  the  Paris  Basin 
Tolypella  reported  by  Grambast.  They  are  undoubtedly  allied  to  the 
Allantoideae.  The  suggestion  by  Sawa  to  remove  Tolypellas  with  an  un- 
divided basal  plate  of  the  oospore  from  the  Nitelleae  seems  unwarranted. 
Many  other  morphological  characteristics  in  common  between  the  genera 
Nitella  and  Tolypella  seem  sufficient  to  place  them  in  the  same  category. 
The  possession  of  an  undivided  basal  plate  in  the  Conoideae,  however, 
indicated  that  this  Section  of  Tolypella  is  intermediate  in  this  respect 
between  the  Allantoideae  and  the  Chareae  and  evolutionarily  nearer. 
As  far  as  lime-shells  are  concerned,  none  have  been  found  in  the  genus 
Nitella,  none  in  the  Allantoideae,  developed  in  the  Conoideae,  may  or 
may  not  be  developed  in  the  Chareae. 

With  the  finding  of  lime-shells  in  Tolypella,  a  basis  is  provided 
for  returning  several  fossil  species  of  charophytes  to  that  genus.  The

lime-shells  of  extant  Tolypella  and  the  fossil  genus  Sphaerochara  (illus- 
trated by  Horn  af  Rantzien,  7,  Plate  X)  are  similar.  Horn  af  Rantzien's 
excellent  photographs  of  Sphaerochara  (Maedlerisphaera)  ulmensis 
could  very  well  be  used  to  illustrate  the  lime-shell  of  Tolypella  prolifera 
which  differs  chiefly  in  size.  It  is  similar  in  shape,  number  of  convolu- 
tions of  the  spiral  cells,  apical  configuration  with  a  groove,  base,  texture 
of  limeshell  and  basal  plug.  The  apex  in  lime-shells  of  T.  intricata 
(Table  1,  no.  9)  was  more  like  that  of  the  fossil  Sphaerochara  heado- 
nensis  without  the  apical  groove.  Horn  af  Rantzien  (8)  removed  several 
species  formerly  assigned  to  Tolypella  to  Sphaerochara  because:  ''Toly- 
pella fructifications  do  not  develope  lime-shells  (Horn  af  Rantzien,  8, 
p.  210)  and  gyrogonites  cannot  accordingly  be  lime-shells  of  fossil 
Tolypella  species."  However,  with  the  finding  of  lime-shells  in  Tolypella, 
that  genus  is  undoubtedly  synonymous  with  Sphaerochara. 

Summary  and  Conclusions 

The  presence  of  an  undivided  basal  plate  of  the  oospore  and  pro- 
duction of  lime-shells  were  found  to  be  consistent  characteristics  in  the 
Section  Conoideae  of  the  genus  Tolypella  while  divided  basal  plates  and 
lack  of  lime-shells  are  consistent  in  the  Allantoideae.  In  these  respects, 
evolutionary  development  apparently  followed  a  trend  from  segmented 
basal  plates  and  lack  of  lime-shells  in  the  genus  Nitella  and  the  Allan- 
toideae of  the  genus  Tolypella  to  unsegmented  basal  plates  and  presence 
of  lime-shells  found  in  the  Conoideae  of  the  genus  Tolypella  and  unseg- 
mented basal  plates  associated  with  or  without  lime-shells  in  the 
Chareae.  The  Conoideae  are  thus  an  intermediate  group  with  reference 
to  these  characteristics.  However,  the  two  sections  of  Tolypella  form  a 
natural  group  based  upon  many  other  characteristics  held  in  common 
and  show  the  greatest  affinity  to  each  other. 

The  finding  of  firm  lime-shells  without  lamination  in  Tolypella 
removes  the  objection  to  placing  fossil  specimens  assigned  to  Sphaero- 
chara in  this  genus.

The  Flowering  of  Lemna  minor  and  the  Establishment  of 
Centaurium  pulchellum  in  Northwestern  Indiana 

Gayton  C.  Marks,  Valparaiso  University 

The  flowering  of  Lemna  minor  is  considered  to  be  an  infrequent 
occurrence  (4,  5,  6).  This  rarity  of  flowering  has  imposed  serious  re- 
strictions on  studies  which  contribute  to  an  understanding  of  the  life 
cycle  of  the  Lemnaceae  (7).  It  has  been  recommended  that,  when  such 
phenomena  occur,  flowering  material  be  collected  for  critical  study   (6). 

Such  an  occasion  did  present  itself  this  summer  while  a  routine 
microscopic  examination  was  made  of  a  Schererville  pond.  The  first 
indication  of  a  serendipitous  find  was  an  almost  transparent  bubble- 
like structure  adjacent  to  several  thalli  of  Lemna  minor.  A  more  critical 
observation  revealed  this  to  be  the  cup-shaped  stigma  attached  to  an 
equally  semi-transparent  style  protruding  from  the  reproductive  pouch 
of  a  parent  duckweed. 

Although  in  no  way  related  to  the  ferns,  the  term  frond  is  com- 
monly employed  in  describing  the  thallus  of  the  duckweeds.  While  there 
seems  to  be  considerable  controversy  in  interpreting  the  inflorescence 
of  this  group,  little  disagreement  exists  in  the  belief  that  the  Lem- 
naceae is  a  degenerate  offshoot  of  the  Araceae. 

Maheshwari  and  Kapil  have  described  the  frond  of  Lemna  pauci- 
costata  as  being  composed  of  three  indistinct  regions:  1.  The  distal  end 
which  is  primarily  photosynthetic  in  function;  2.  A  nodal  sector  flanked 
by  the  reproductive  pouches,  and  from  which  arise  the  root,  the  daugh- 
ter fronds  and  the  flowers;  3.  A  basal  axial  region  from  which  arises 
a  pedicel  and  is  partly  modified  to  form  the  pouches.  The  frond  is  asym- 
metric, largely  undifferentiated  and  somewhat  broader  at  the  distal  end 
(V). 

With  the  exception  of  the  pedicel,  this  description  may  be  cautiously 
applied  to  Lemna  minor.  Environmental  conditions  often  lead  to  such 
variation  that  species  are  not  readily  distinguished    (3,  8). 

The  primordium  of  the  foot  arises  from  a  subepidermal  layer  which 
is  overarched  by  a  protective  sheath  of  epidermis.  This  sheath  is  soon 
pierced  by  a  root  cap  which  becomes  winged  in  L.  paucicostata  but  not 
L.  minor.  The  epidermis  is  without  root  hairs.  The  anatomy  of  the 
root  reveals  four  layers  of  cells.  While  the  outer  two  are  chlorophyllous, 
the  inner  two  are  devoid  of  pigment  and  may  be  compared  to  the  en- 
dodermis  and  the  xylem  respectively.  The  vascular  strand  in  the  frond 
is  simple.  In  L.  paucicostata,  it  is  composed  of  a  narrow  strip  of  elon- 
gated cells.  In  Lemna  minor,  these  cells  may  become  lignified    (7). 

The  question  of  the  floral  assemblage  is  more  difficult  to  assess.  It 
commonly  has  been  interpreted  as  several  flowers  (usually  one  female, 
two  males)  in  a  common  membranous  spathe  (1,  4,  5).  Pool  describes 
the  family  as  bearing  extremely  simple  flowers  consisting  of  one  stamen 
and  one  pistil   (9).  In  L.  paucicostata  the  pistil  is  lateral  with  respect 

414 


Plant  Taxonomy  415 

to  the  stamens,  but  in  L.  minor  the  carpel  lies  between  two  stamens.  The 
latter  arrangement  lends  support  to  the  view  that  what  is  usually  con- 
sidered an  infloresence  is  in  reality  a  flower  (7). 

If  this  assumption  is  true,  it  may  be  appropriate  to  consider  this 
species  as  near  polygamomonecious  since  what  seem  to  be  perfect  flowers 
and  staminate  flowers  may  be  borne  on  the  same  individual.  It  has  been 
the  practice  to  regard  this  entire  group  as  monecious   (1,  10). 

As  earlier  stated,  the  first  indication  of  the  flowering  process  was 
the  appearance  of  style  and  stigma.  Closer  scrutiny  revealed  that  the 
pistil  was  flanked  on  either  side  by  immature  stamens.  This  discovery 
prompted  a  quantitative  study.  Of  six  hundred  plants  examined  on 
June  19,  95  or  15.8%  bore  this  type  of  "flower."  At  this  point  it  sud- 
denly became  apparent  that  a  second  type  of  "flower"  was  present,  this 
being  entirely  staminate,  composed  of  two  stamens  only.  The  next  four 
hundred  plants  examined  on  this  same  day  produced  113  "flowers"  of 
either  the  perfect  or  staminate  type.  This  represented  about  28%  of 
the  total  population. 

On  June  23  a  duckweed  sampling  was  taken  from  a  small  lake  near 
St.  John.  Only  five,  or  less  than  2%  of  three  hundred  plants  examined, 
yielded  flowering  individuals.  On  the  same  day  the  original  Schererville 
pond  yielded  28  flowering  plants  of  one  hundred  studied.  On  June  25,  a 
ditch  connected  to  the  Kankakee  River  near  Schneider  was  explored 
for  flowering  specimens.  None  of  the  one  hundred  plants  examined 
exhibited  "flowers."  The  Schererville  pond  produced  117  flowering  plants 
of  two  hundred  examined  on  July  9.  This  represented  approximately 
58%  of  the  population.  By  August  29,  this  percentage  dropped  to  31%, 
and  by  September  17  it  was  estimated  that  this  percentage  had  declined 
to  about  15%. 

Statistical  errors  are  easily  introduced  because  of  the  sampling 
techniques  used.  Chief  among  these  is  properly  identifying  one  plant. 
As  in  other  duckweeds,  L.  minor  reproduces  asexually  by  buds  or  daugh- 
ter fronds  in  the  same  reproductive  pouches  where  flowering  occurs.  In 
most  cases  the  daughter,  granddaughter  and  great  granddaughter  fronds 
remain  attached  to  the  parent  frond  forming  a  chain  of  thalli.  Even 
gentle  manipulation  produces  fragmentation  so  that  the  pure  definition 
of  a  plant  is  at  best  obscure.  A  lesser  obstacle  was  the  immaturity  of 
the  stamens.  Few  seemed  to  reach  anthesis.  Many  remained  subepidermal 
and  had  to  be  gently  pressed  out  with  a  teasing  needle  to  prove  their 
existence.  Of  the  hundreds  of  flowers  observed,  only  a  few  anthers  ex- 
hibited dehiscence.  The  anthers  are  tetralocular,  but  all  four  micro- 
sporangia  do  not  develop  synchronously.  One  cell  may  be  metaphase 
while  others  in  early  prophase  (7). 

The  stigma  and  style  appear  to  be  but  one  cell  thick.  There  is  but 
one  ovule  in  an  ovary  and  this  may  be  removed  with  little  difficulty.  The 
membranous  sac  (spathe)  which  invests  the  "perfect  flowers"  is  curiously 
but  sparingly  pigmented  with  red  spots. 

With  a  great  amount  of  disappointment,  no  fruiting  has  been  ob- 
served.

In  the  Flora  of  Indiana,  Deam  listed  Centaurium  pulchellum  as  an 
excluded  species  (2).  He  had  received  a  report  of  a  specimen  from  the 
Dunes  area  without  a  specific  locality  and  had  seen  a  plant  collected  in 
South  Chicago.  He  cautiously  preferred  to  "wait  and  see"  if  this  species 
would  establish  itself  in  Indiana. 

Centaurium  pulchellum  is  a  member  of  the  Gentianaceae.  It  produces 
a  handsome  flower  with  a  salverform  corolla  and  is  pleasingly  pink. 
Three  or  four  specimens  were  found  cringing  from  periodic  onslaughts 
of  a  power  mower  in  a  Schererville  lawn  in  midsummer  of  1968.  Since 
that  time  abundant  stands  have  been  found  near  the  hangars  and  on  run- 
ways of  the  Griffith  airport  at  the  eastern  edge  of  that  community.  These 
plants  seemed  stunted  and  judging  from  other  plants,  this  could  be 
explained  on  the  basis  of  soil.  A  smaller  but  more  luxuriant  population 
was  found  on  the  extreme  southern  edge  of  Griffith  in  late  summer.

Fluctuations  of  Bacteriological  Numbers  in  Farm  Ponds.  L.  E.  Hughes 
and  H.  W.  Reuszer,  Purdue  University. — Studies  of  the  fluctuations  of 
bacterial  numbers  in  farm  ponds  was  conducted  for  sixteen  months.  These 
studies  were  conducted  in  three  ponds,  Ponds  A,  B,  and  C.  Samples  were 
taken  approximately  once  each  month  from  both  the  surface  water  and 
water  near  the  bottom  of  each  pond. 

Bacterial  numbers  in  Pond  B  were  about  equal  in  the  bottom  water 
and  the  surface  water  throughout  the  year,  ranging  from  about  5,000 
per  ml  in  August,  1967,  to  somewhat  greater  than  40,000  per  ml  in 
May,  1967.  Larger  numbers  and  greater  fluctuations  of  bacterial  num- 
bers were  found  in  Ponds  A  and  C,  with  generally  higher  bacterial  num- 
bers in  the  bottom  water  of  Pond  A  than  in  the  surface  water,  while 
generally  higher  numbers  occurred  in  the  surface  water  of  Pond  C  than 
in  the  bottom  water. 

Some  factors  influencing  these  bacterial  numbers,  including  total 
carbon,  have  also  been  studied.  Pond  B  had  consistently  lower  total 
carbon  values  in  both  the  surface  water  and  bottom  water  than  did  Ponds 
A  or  C  with  values  ranging  from  7.0  mg  per  liter  to  11.6  mg  per  liter. 
Pond  A  had  values  as  high  as  16  mg  per  liter  while  Pond  C  had  even 
higher  values,  ranging  up  to  22  mg  per  liter.

Tillage  Techniques  on  Indiana  Prairie  Soil1 

Helmut  Kohnke  and  S.  A.  Barber,  Purdue  University 

Abstract 

Several  variations  of  tillage  methods  and  of  residue  management  on 
a  fertile  prairie  soil  during  six  years  have  resulted  in  only  minor  effects 
on  corn  yields.  Even  the  no  tillage  plots  produced  corn  within  2.5  percent 
of  the  conventionally  treated  plots.  However,  distinct  changes  in  soil 
properties  were  observed.  These  point  to  eventual  major  effects  on  the 
productivity  of  the  soil. 

Introduction 

The  introduction  of  increasingly  more  powerful  tractors  has  made  it 
possible  to  combine  several  tillage  operations  that  formerly  have  been 
performed  by  horse-drawn  equipment.  Recognition  of  the  danger  of 
erosion  has  pointed  to  the  need  of  keeping  the  soil  surface  receptive  for 
water  in  order  to  avoid  excessive  runoff.  Considerably  increased  fertiliza- 
tion, especially  with  nitrogen  compounds,  and  use  of  herbicides  have 
caused  many  farmers  to  change  from  crop  rotations  that  included  grass 
and  legume  meadows  to  continuous  cropping  with  corn  and  soybeans. 

Historically  one  reason  for  tillage  has  been  to  stimulate  the  de- 
composition of  the  mineral  and  organic  components  of  the  soil  in  order 
to  provide  an  adequate  nutrient  supply  for  the  succeeding  crop.  With  the 
plentiful  and  relatively  inexpensive  fertilizers  available  this  reason  has 
ceased  to  exist. 

All  these  facts  have  caused  the  introduction  of  new  systems  of  tillage 
and  of  crop  residue  management  during  the  last  two  decades.  How  do 
crop  yields  and  soil  quality  react  to  this  change?  In  an  attempt  to  find 
quantitative  answers  an  experiment  has  been  conducted  on  the  Purdue 
University  Agronomy  Farm  comparing  several  tillage  treatments  for 
corn.  It  is  the  purpose  of  the  research  reported  in  this  paper  to  determine 
what  effects  continuous  cropping  with  corn  has  on  soil  conditions  and 
corn  yields  under  various  types  of  tillage. 

Experimental  Procedure 

An  experiment  has  been  designed  in  which  four  systems  of  tillage, 
and  four  levels  of  residues  were  used.  Corn  was  planted  annually  on  six 
of  the  treatments,  while  two  treatments  remained  without  any  crop. 
Every  year  fertilizer  is  uniformly  broadcast  over  the  entire  area  at 
rates  designed  to  result  in  high  yields.  Herbicides  are  used  and  the  plots 
with  corn  are  cultivated  twice  during  the  season. 

The  treatment  are  given  in  Table  1. 

The  design  of  this  experiment  permits  the  comparison  of  the  effects 
of  corn  versus  no  corn,  and  of  the  relative  effects  of  four  tillage  methods.

The  items  that  were  studied  include  yield,  stalk  diameter,  and  root  growth 
of  corn  and  organic  matter  content,  pore  space,  and  aggregation  of 
the  soil. 

The  soil  of  the  experimental  area  is  a  mollisol,  a  tall  grass  prairie 
soil,  grading  from  a  Raub  silt  loam  to  a  Chalmers  silt  loan.  Table  2  pre-

Except  for  the  variables  studied  all  other  treatments  were  identical 
for  the  entire  experimental  area.  The  same  corn  hybrid  was  used.  Fertili- 
zation consisted  of  an  annual  application  of  250  lbs  N,  100  lbs  P205,  and 
100  lbs.  K20  per  acre.  Atrazine  at  a  rate  of  4  lbs /acre  was  used  to  con- 
trol grassy  weeds.  In  the  fall  the  stover  on  all  plots  was  cut  with  a  stalk 
cutter. 

Conventional  tillage  (treatments  1,  2,  3,  7)  consisted  of  plowing  to 
20  cm  and  disking  three  times.  Whenever  the  soil  moisture  conditions 
permitted  plowing  was  done  in  the  fall.  All  other  operations  were  done 
immediately  preceding  corn  planting.  The  field  cultivator  (Graham- 
Hoeme  type)  was  used  twice  to  a  depth  of  20  cm.  The  rototiller  loosened 
the  entire  surface  soil  to  about  8  cm  depth.  Both  these  treatments  included 
two  cultivations.  The  soil  of  these  treatments    (4  and  5)    were  disked

twice.  In  the  case  of  the  "no  tillage"  treatment  the  corn  planter  was 
used  twice  in  succession  in  order  to  get  the  seed  deep  enough  into  the 
ground.  The  soil  treatments  1,  2,  3,  4,  5,  and  7  were  cultivated  twice.  Since 
treatments  6  and  8  were  not  cultivated  they  received  an  application  of 
2,  4-D  in  addition  to  the  atrazine. 

While  treatment  7  (no  corn)  was  managed  in  exactly  the  same 
manner  as  treatments  1,  2,  and  3,  treatment  8  (no  corn)  consisted  ex- 
clusively of  application  of  fertilizers  and  herbicides. 

Results  and  Discussion 
Corn  Yields 

The  average  coin  yields  of  the  four  plots  of  each  of  the  treatments 
during  the  first  six  years  of  the  experiment  are  given  in  Table  3.  Figure 
1  compares  the  yields  of  three  of  the  treatments  with  the  average  yields 
for  the  State  of  Indiana  and  Tippecanoe  County  during  the  same  years. 
The  effect  of  the  changing  weather  from  year  to  year  is  quite  evident.  The 
yields  from  the  field  cultivator  plots  have  been  consistently  the  highest. 
The  yields  from  the  three  "Conventional  tillage"  treatments  and  from 
the  rototiller  treatment  did  not  vary  statistically  from  each  other.  Prob-

ably  the  most  astonishing  result  is  that  the  average  yield  of  the  no-tillage 
treatment  was  only  five  percent  lower  than  that  of  conventional  treat- 
ment. This  difference  becomes  still  smaller  when  the  first  two  years  are 
excluded  from  the  comparison  (2.5  percent  difference).  In  the  first  two 
years  the  no-tillage  treatment  suffered  from  inadequate  stand  because 


Soil  Science  423 

of  the  difficulty  to  get  the  seed  into  the  ground.  This  small  difference  in 
yield  indicates  that  the  soil  of  the  experimental  area  is  very  favorable  for 
corn  growth  even  without  any  tillage  treatment. 

It  is  interesting  to  note  (Figure  2)  that  the  differences  in  yield  due 
to  differences  in  treatment  were  smaller  than  due  to  the  variations  due  to 
weather  from  year  to  year. 
Roots 

The  root  distribution  of  corn  in  one  of  the  "conventional  tillage" 
plots  was  compared  with  that  in  a  "no  tillage"  plot  (Figure  3).  At  a 
location  6  inches  from  the  plant  "conventional"  corn  had  three  times  the 
weight  of  roots  as  "no  tillage"  corn.  At  a  location  20  inches  from  the 
plant  (midway  between  the  rows)  this  ratio  was  two  to  one.  In  spite  of 
this  great  difference  in  root  growth  yields  were  quite  similar.

In  the  seventh  year  of  the  experiment  (1968)  all  plots  were  planted 
to  corn,  otherwise  the  treatments  remained  the  same.  A  measurement  of 
the  diameters  of  the  cornstalks  (Figure  4)  indicates  the  cumulative  effects 
of  six  years  of  differential  treatments.  The  three  conventional  plow 
treatments  and  the  field  cultivator  treatment  gave  about  the  same  re- 
sults. The  biggest  diameters  occurred  in  the  roto-till  plots.  There  was  a 
definite  decrease  of  diameters  in  the  plots  that  had  been  fallow  for  six 
years  as  well  as  in  the  no-tillage  plots.  These  latter,  as  has  been  men- 
tioned before,  had  a  substantially  smaller  amount  of  roots  than  the 
conventionally  treated  plots. 

Organic  matter  content  of  the  soil 

The  organic  matter  content  of  the  soil  of  the  various  treatments 
was  determined  anually  since  1965.  Because  the  organic  matter  content 
of  the  surface  soil  has  the  greatest  effect  on  the  moisture  regime  most 
of  the  determinations  were  made  on  soil  of  the  0-4  inch  depth.  While  there 
have  been  variations  from  year  to  year  the  relations  of  organic  matter

content   from    treatment    to    treatment   have    essentially    remained    the 
same.  Table  4  shows  the  organic  matter  situation  in  the  spring  of  1968. 

It  is  interesting  to  note  that  the  highest  organic  matter  content  in 
the  surface  soil  occurs  in  the  roto-tiller  plots  where  the  residues  are 
incorporated  in  the  upper  four  inches  only.  Leaving  the  residues  on  top 
of  the  ground  as  done  in  the  no-tillage  plots  evidently  causes  them  to 
decompose  more  quickly.  The  addition  of  extra  residues  has  resulted  in 
a  substantial  increase  in  organic  matter  compared  to  leaving  the  normal 
amount  of  residues  in  the  field.  As  was  to  be  expected  removing  the 
residues  reduced  the  organic  matter  content  considerably.  Leaving  the 
soil  bare  of  any  vegetation  (treatments  7  and  8)  resulted  in  a  decline  of 
the  organic  matter  content  even  greater  than  where  only  the  corn  roots 
were  left  in  the  ground  (treatment  2). 

After  six  years  of  conventional  cropping  with  corn  the  soil  had 
0.4%  more  organic  matter  than  the  soil  that  remained  fallow  for  the

same  period.  This  represents  an  average  annual  loss  of  1300  lbs  per 
acre  of  organic  matter  (dry  basis)  from  the  soils  that  had  no  vegetation. 
Surely  an  outstanding  testimony  for  the  value  of  corn  as  a  soil  conserving 
crop — under  conditions  of  high  fertilization  and  no  erosion! 

In  all  the  treatments  in  which  the  soil  was  tilled  down  to  20  cm,  the 
organic  matter  content  was  rather  uniform  to  this  depth.  In  the  rototill 
and  the  no-till  plots,  however,  there  was  a  substantial  decrease  of 
organic  matter  below  10  cm.

very  little  lasting  influence  of  the  treatments.  Only  the  roto-tilled  plots 
(treatment  5)  had  a  substantially  higher  aeration  porosity  in  the  spring 
than  the  other  treatments.  The  data  for  October  1967  are  a  direct  reflec- 
tion of  the  mechanical  treatments.  Most  of  the  soils  have  maintained  their 
loose  structure  throughout  the  growing  season.  The  greatest  decrease 
of  porosity  of  the  "conventionally"  treated  plots  occurred  in  treatment 
7  where  no  vegetation  existed  that  could  have  protected  the  soil  from 
the  impact  of  the  rain. 

Previous  experience  has  shown  that  10  percent  aeration  porosity  in 
the  upper  root  zone  is  sufficient  for  satisfactory  corn  growth.  In  most 
of  the  treatments  the  actual  aeration  porosity  in  the  spring  before  culti- 
vation was  somewhat  lower  than  this  value.  This  indicates  a  need  for 
loosening  of  the  soil  and  the  reason  for  a  decrease  in  yield  of  corn  on  the 
no-tillage  treatment. 

The  water-stable  aggregation  of  the  soil  of  the  various  treatments 
was  determined  by  the  wet-sieving  method  (Figure  6).  Most  of  the  soils 
showed  rather  satisfactory  values  between  0.25  and  0.35  mm  aggregation 
index.  The  two  treatments  with  accumulation  of  organic  residues  in  the 
surface  (Nos.  5  and  6)  had  considerably  greater  aggregation  indices.  The 
no-corn,  conventional  tillage  treatment  (No.  7)  had  the  lowest  value.  The 
fact  that  no  organic  matter  was  added  and  that  the  cultivation  caused 
oxidation  of  the  most  active  part  of  the  humus  may  be  the  reason  for  this. 

Temperature  fluctuations 

A  temperature  study  conducted  in  the  summer  of  1966  showed 
interesting  differences  in  daily  temperature  fluctuations  between  the 
treatments.  These  data  are  shown  in  Table  5. 

The  fact  that  temperature  fluctuations  in  the  soil  increase  with 
increasing  thermal  conductivity  is  clearly  brought  out  by  these  data.  The 
corn  in  treatments  1  and  2  reduced  insolation  compared  to  treatments 
7  and  8.  The  corn  residue  plowed  into  the  soil  of  treatment  1  reduced  the 
thermal  conductivity  compared  to  treatment  2,  from  which  the  residues 
were  removed.    The  much  denser  structure  of  the  no-tillage  soil  (treat-

ment  8)  had  a  higher  thermal  conductivity  than  the  soil  of  treatment  7 
which  has  been  plowed  every  year. 

The  greater  the  daily  soil  temperature  fluctuations  are,  the  greater 
are  the  vapor  pressure  fluctuations  and  consequently  losses  of  soil  mois- 
ture in  the  vapor  phase.  These  data  indicate  clearly  that  protection  from 
insolation  and  incorporation  of  crop  residues  into  the  soil  assist  in  mois- 
ture conservation. 

Conclusion 

During  the  six  years  this  experiment  has  run  the  effects  of  tillage  and 
crop  residue  management  on  corn  yields  have  not  been  great.  However, 
the  changes  in  the  physical  conditions  of  the  soil  have  been  pronounced. 
As  compared  with  corn  produced  with  conventional  tillage,  some  treat- 
ments caused  a  decrease  in  soil  physical  conditions,  whereas  other  treat- 
ments improved  them.  Where  the  practices  used  cause  a  marked  reduc- 
tion in  one  or  more  of  the  physical  conditions  this  portends  a  warning 
that  these  changes  could  eventually  cause  yield  decreases.  If  this  is  true 
on  the  fundamentally  very  productive  mollisols,  it  would  be  much  more 
so  on  soils  of  lower  quality.  The  farmer  must  stay  forever  vigilant  to  use 
the  best  management  practices  for  his  soil. 


Fitting  Plants  to  Fragipan  Soils  in  Southern  Indiana 

Maurice  E.  Heath,  Purdue  Agricultural  Experiment  Station 

This  paper  deals  with  recent  research  and  observations  of  fragipan 
soils  and  plant  relations  found  in  the  southern  Indiana  sandstone  shale 
soil  region  (Figure  1).  These  soils  comprise  2,348,000  acres — nearly  a 
tenth  of  the  state.  The  sandstone  shale  soil  region  extends  into  all  or 
parts  of  19  counties.  It  is  an  unglaciated  area  with  deeply  cut  valleys  and 
rolling  to  steep  topography.  Approximately  40  percent  of  the  area  is 
wooded — too  steep  for  the  use  of  farm  equipment.  The  native  pH  of  the 
loess  covered  hills  ranges  from  5-3  to  5.5.

Figure  1.  The  sandstone  shale  soil  region  (in  black)  extends  into  all  or 
parts  of  the  19  southern  Indiana  counties.  Soil  fragipans  are  commonly 
found  throughout  the  area. 


The  Environmental  Model 

Soil  fragipans  restrict  moisture  movement  as  well  as  root  depth 
development.  Fragipans  are  formed  under  low  pH  in  humid  areas  (8). 
Plant  roots  will  not  penetrate  the  fragipan  unless  through  a  cleavage  or 
crevice.  Thus,  for  many  of  these  soils,  the  shallow  root  zone  depth  will 
commonly  range  from  18  to  34  inches  (7).   The  root  zone  water  holding

capacity  may  range  from  less  than  4  to  4%  inches   (5).    The  fragipan 
itself  may  range  from  10  to  15  inches  in  thickness. 

Rainfall  averages  40  to  46  inches  annually.  Soils  are  often  water- 
logged in  winter  and  very  early  spring.  Nearly  half  the  rainfall  is  lost  as 
run-off.  There  is  little,  if  any,  lasting  snow  cover  during  winter  with 
diurnal  temperatures  frequently  fluctuating  above  and  below  freezing. 
Tap  rooted  alfalfa  is  a  high  risk  crop.  The  total  vertical  winter  soil  motion 
during  1965-66  was  shown  to  range  from  22.03  inches  at  the  surface  to 
0.39  inches  at  the  12-inch  soil  depth  (3).  It  was  considerably  greater 
during  the  winter  of  1966-67.  Droughts  are  common  in  mid-summer. 
Moisturewise  the  root  zone  is  an  environment  of  extremes — from  wet 
to  dry. 

Since  1953,  when  research  first  started  on  the  Southern  Indiana 
Forage  Research  Farm  (Dubois  County),  several  major  environmental 
differences  have  been  observed  between  the  Brookston-Crosby  soil  area 
(Lafayette)  and  the  sandstone  shale  area  (Forage  Farm).  The  observed 
differences  are  as  follows:

Examples  of  agronomic  crops  considered  low  risk  for  the  Brookston-

grass.  For  the  sandstone  shale  soil  region  examples  of  low  risk  agronomic 
crops  are  the  sorghums,  winter  wheat  and  rye,  red  clover,  Korean 
lespedeza  and  tall  fescue. 

Fitting  Crop  Plants  and  Practices  to  the  Environmental  Model 

To  protect  many  of  these  hillside  soils  from  the  ravages  of  erosion 
it  would  appear,  in  general,  that  either  the  natural  vegetation  of  wood-

land  or  a  close  growing  adapted  forage  grass  and/or  crop  plant  must  be 
employed.  Several  grasses,  legumes  and  agronomic  practices  of  promise 
will  be  discussed. 

Tall  fescue  (Festuca  arundinacca  Schreb),  a  perennial  forage  grass, 
is  a  comparatively  late  comer  to  Indiana.  Kentucky  31  tall  fescue  was  dis- 
covered in  1931  on  Mr.  William  Suiter's  farm  in  Menefee  County,  Ken- 
tucky. It  was  not  publicized  greatly  until  about  1945.  Since  that  time 
thousands  of  acres  of  tall  fescue  have  been  seeded  on  hill  land  fragipan 
soils  in  Southern  Indiana.  It  has  particular  adaptation  to  this  environ- 
ment of  extremes  from  wet  to  dry  and  greatly  insulates  the  soil  surface 
reducing  freezing  and  thawing  during  winter.  Presently  it  is  by  far  the 
most  adapted  grass  for  these  conditions.  Much  research  is  now  underway 
to  learn  how  to  use  this  grass  more  profitably  in  a  livestock  system  on 
these  kind  of  soils.  Excellent  winter  pastures  of  tall  fescue  have  been 
produced  for  beef  cows  using  the  practice  of  the  round  bale  and  aftermath 
growth   (Figure  2)   rationed  with  an  electric  fence   (6). 


Figure  2.  This  hill  land  field  was  reclaimed  from  abandonment  in  1957  and 
seeded  to  tall  fescue.  With  the  round  bale  and  ration  grazing  technique 
and  a  practical  level  of  fertilization,  as  much  as  180  beef  cow  pasture  days 
per  acre  in  mid-winter  has  been  achieved.

Reed  canarygrass  (Phalaris  arundinacea  L.)  performance  results 
elsewhere  would  strongly  indicate  that  it  fits  this  environmental  model  of 
extremes — from  wet  to  dry.  It  is  now  being  evaluated  as  a  possible 
drought  pasture  for  beef  cows  on  the  overflow  valley  soils  with  slow  per- 
meability. Here  again,  the  rationed  round  bale-aftermath  pasture  looks 
promising  to  bridge  the  summer  drought. 

Several  perennial  lateral  rooted  legumes  appear  promising  for  use 
on  these  kinds  of  soils.  Crownvetch  (Coronilla  varia  L.)  when  managed 
as  a  hay  plant  has  shown  very  good  response  (2).  In  1954  roadside  plots 
10  feet  in  width  were  seeded.  Ten  years  later  the  crownvetch  had  spread 
75  feet  much  of  the  spreading  was  through  a  good  tall  fescue  sod.  In  fact, 
crownvetch  allowed  to  reach  full  bloom  will  shade  out  tall  fescue.  The 
composition  of  crownvetch  is  reported  by  several  workers  to  be  similar  to 
that  of  alfalfa.  Crownvetch  research  is  continuing  as  to  its  place  in 
mixtures  for  hay  production,  beef  cattle  acceptability,  fertility  and 
management   requirements   for   intensified   production. 

Zigzag  clover  (Trifolium  medium  L.)  planted  in  1955  has  spread  a 
distance  of  25  feet  through  a  dense  tall  fescue  sod.  Zigzag  clover  in 
bloom  from  a  distance  resembles  red  clover.  Baled  zigzag  clover  hay  has 
been  consumed  as  readily  by  beef  cows  as  other  common  hays.  Currently 
it  is  necessary  to  propagate  vegetatively  due  to  a  lack  of  a  good  seed  pro- 
ducing type.  A  small  root  nursery,  approximately  10'  x  20'  in  size,  has 
been  established  on  a  selected  farm  in  each  of  15  counties  of  the  sand- 
stone shale  soil  region.  As  these  nurseries  develop  it  is  planned  to  use 
the  roots  for  propagation.  With  the  aid  of  a  mechanical  planter  the 
4-  to  6-inch  root  cuttings  will  be  planted  in  hillside  pasture  and  meadow 
sods.  Field  observations  will  be  made  under  actual  farm  conditions  while 
at  the  same  time  small  plot  management  trials  will  be  expanded  at  the 
Forage    (research)   Farm. 

In  1954  several  big  trefoil  accessions  from  the  Pacific  Northwest 
were  tested  on  the  Forage  Farm  but  did  not  prove  winter  hardy.  How- 
ever, in  1964,  I  identified  big  trefoil  (Lotus  uliginosus  Schkuhr)  growing 
on  Mr.  Clarence  Kaiser's  farm  in  Crawford  county.  Mr.  Kaiser  had 
observed  this  legume  growing  and  spreading  in  eight  different  areas  in  a 
well  fertilized  tall  fescue  meadow.  He  thought  it  to  be  birdsfoot  trefoil 
(L.  corniculatus  L.).  The  field  was  managed  as  hay  in  the  spring  and 
then  grazed  the  rest  of  the  season.  Three  of  the  eight  ecotypes  obtained 
from  Mr.  Kaiser's  tall  fescue  field  have  shown  excellent  forage  and  seed 
production  characteristics  in  small  plots  on  the  Forage  Farm.  Presently 
seed  is  being  increased  of  the  three  ecotypes  and  will  be  further  tested 
for  hay  and  pasture  use.  They  look  very  promising  to  grow  with  fescue 
on  these  soils.   Big  trefoil  has  tolerance  to  wet  soils  and  low  pH. 

Lateral  rooted  alfalfa  has  been  reported  to  be  much  more  tolerant 
to  heaving  than  the  commonly  used  tap  rooted  alfalfas  (4).  In  an  attempt 
to  tailor  make  a  lateral  rooted  alfalfa  that  would  be  happy  in  this  environ- 
ment, Dr.  R.  L.  Davis  made  many  crosses  between  the  lateral  rooted  and 
tap  rooted  types.  These  were  grown  on  the  Forage  Farm  f ragipan  soils  for 
several  years  and  their  growth  characteristics  observed.  The  best  growing 


Soil  Science  433 

and  spreading  crosses  were  selected  for  further  screening  in  the  green- 
house. From  these,  the  best  genotypes  were  combined  into  an  experi- 
mental synthetic  (1).  Currently  the  experimental  is  being  "on  farm" 
tested  in  eight  counties  in  the  sandstone  shale  area.  Management  research 
is  also  being  conducted  on  the  Forage  Farm.  The  goal  is  an  alfalfa  that 
will  give  persistence  of  stand  along  with  acceptable  productivity  for 
pasture  and  hay. 

Crambe,  a  new  industrial  oil  seed  crop  of  promise,  fits  this  environ- 
mental model  when  planted  in  mid-April.  It  can  be  harvested  approxi- 
mately 85  days  after  planting  and  prior  to  the  mid-summer  drought.  It 
has  excellent  seedling  vigor  and  can  be  grown  in  close  drills.  It  will  fur- 
nish much  soil  protection  from  raindrop  energy  in  a  short  period  of  time 
after  seeding.  It  is  visualized  that  the  crambe  crop  could  be  followed  by 
a  summer  seeding  of  grasses  and  legumes  in  August  or  by  a  wheat  or  rye 
crop  in  the  fall. 

Tall  fescue  sod  planting  on  hill  land  looks  promising.  The  idealized 
model  would  provide  sod  dormancy  for  approximately  two  months  while 
the  summer  annual,  such  as  sorghum,  became  sufficiently  developed  to 
shade  the  fescue.  After  the  sorghum  matured  the  fescue  would  again 
grow  to  furnish  fall  pasture  along  with  the  sorghum  residue  and  provide 
an  improved  pasture  or  hay  meadow  the  following  year.  Thus  far  we 
have  not  found  a  satisfactory  growth  regulator  to  obtain  consistent  sod 
dormancy.  Presently,  it  is  necessary  to  use  cover  crops  and  reseed 
following  sod  planting  on  sloping  land. 

Summary 

1.  The  environmental  model  of  the  unglaciated  sandstone  shale 
fragipan  soils  in  Southern  Indiana  is  a  contrast  of  extremes  when  com- 
pared to  the  well  drained  corn  soils  of  Central  Indiana,  thus  requiring 
plants  with  special  adaptation. 

2.  Presently,  tall  fescue  is  the  most  adapted  perennial  grass  to 
furnish  hillside  protection  and  stabilization. 

3.  Lateral  rooted  legumes  of  promise  are  being  tested  as  associates 
to  grow  with  tall  fescue  and  other  grasses  to  further  improve  the  forage 
quality  and  productivity  on  these  hill  land  soils.  Crambe,  a  promising 
industrial  crop,  also  appears  to  fit  the  environmental  model. 

4.  Special  cultural  and  management  practices  such  as  sod  planting 
and  the  rationed  round  bale  technique  for  winter  and  summer  drought 
pastures  appear  very  promising  on  these  kinds  of  soils.

Fertilizer  Experiments  with  Corn  on  Several  Soils  in 
Indiana,  1963-19651 

Russell  K.  Stivers,  Purdue  University2 

The  primary  purpose  of  this  research  was  to  study  the  response  of 
continuous  com  (Zea  mays  L.)  to  phosphorus  and  potassium  fertilization 
on  several  different  soils  in  Indiana.  Barber  and  Humbert  (1),  after 
reviewing  advances  in  the  knowledge  of  potassium  fertilization  from 
1951  to  1961,  concluded  that  more  data  are  needed  on  the  relationship 
between  crop  response  to  added  potassium  and  the  level  of  available 
potassium  in  the  soil.  On  a  Runnymede  loan  testing  medium  in  potassium, 
Stivers  and  Griffith  (7)  found  that  it  took  four  years  of  cropping  with 
continuous  high  yielding  corn  before  a  significant  yield  increase  with 
potassium  fertilizer  was  obtained.  It  was  thought  that  ths  soil  might 
have  fixed  potassium  since  the  increase  in  available  soil  potassium,  after 
four  years  of  applying  100  pounds  per  acre  of  potassium  annually,  was 
small.  Barber  and  Humbert  (1)  state  that  soil  type  may  have  to  be 
considered  more  in  the  future  because  of  the  relationship  between  soil 
type  and  potassium  fixation  and  potassium  release. 

Barber  and  Stivers  (2)  have  reported  that  broadcast  and  plow  under 
phosphorus  fertilizer  is  more  important  than  row  phosphorus  fertilizer 
for  corn  when  more  than  17  pounds  per  acre  of  phosphorus  is  applied. 
At  low  soil  test  levels,  corn  yields  were  increased  by  row  applications  of 
phosphorus,  but  not  a  medium  and  high  levels. 

Methods  and  Procedures 

Different  rates  and  placements  of  commercial  fertilizers  were  applied 
to  soils  on  field  plots  on  which  corn  was  grown.  Height,  yield  of  grain 
and  chemical  composition  of  the  ear  leaf  were  determined. 

These  experiments  were  conducted  on  three  different  farms,  all  of 
which  were  in  Tippecanoe  County  (Table  1).  The  phosphorus  fertility  and 
the  potassium  fertility  experiments  on  the  Gwin  Farm  were  adjacent  to 
each  other  at  the  same  location.  The  Byers  and  Brown  farms  experiments 
were  initiated  in  1963;  the  two  experiments  on  the  Gwin  Farm  were 
initiated  in  1964. 

One  of  the  three  replications  on  the  Byers  Farm  was  on  Fincastle 
soil,  and  two  replications  were  on  Russell  soil  (Table  1).  On  the  Gwin 
Farm,  no  clear  demarcation  between  Martinsville  and  Russell  soils  was 
made.  The  two  soils  are  very  similar  except  that  Martinsville  has  coarser 
parent  material  in  the  D  horizon  and  is  slightly  more  droughty  than 
Russell.

On  the  Crosby  soil  location  and  on  the  Fincastle  and  Russell  soils 
location,  three  replications  were  used.  Experimental  design  was  an  unbal- 
anced incomplete  block  design  with  28  treatments.  A  randomized  complete 
block  design  with  four  replications  was  used  for  the  Martinsville  and 
Russell  soils  experiments.  All  plots  were  65  feet  long  and  four  42-inch 
corn  rows  wide.  The  center  two  rows  minus  five  feet  for  border  on  each 
end  were  harvested. 

Soil  samples  were  taken  prior  to  the  start  of  each  experiment  from 
every  plot.  Fifteen  or  more  cores  were  taken  seven  inches  deep  in  each 
plot  and  composited  for  one  sample.  They  were  then  air  dried,  screened 
and  mixed,  and  subsamples  were  tested  by  the  Purdue  Soil  Testing 
Laboratory  using  methods  of  Spain  and  White  (5,  6). 

On  the  Fincastle  and  Russell  soils  having  a  pH  of  5.6,  two  and 
one-half  tons  of  agricultural  limestone  were  applied  before  plowing,  and 
one  and  one-half  tons  of  limestone  were  applied  after  plowing  in  1963. 
On  Crosby  soil  agricultural  limestone  was  applied  at  the  rates  of  one  and 
one-half  tons  per  acre  before  plowing  and  three-fourths  ton  per  acre  after 
plowing  in  1963.  In  1964,  three  and  three-quarters  tons  per  acre  of  agri- 
cultural limestone  were  applied  to  the  same  soil  and  plowed  under  for  the 
phosphorus  and  potassium  experiments. 

Fertilizer  materials  used  were  33.5  percent  nitrogen  from  ammonium 
nitrate,  24  percent  phosphorus  from  superphosphate  in  1963  and  1965 
and  9  percent  phosphorus  from  superphosphate  in  1964,  and  50  percent 
potassium  from  muriate  of  potash. 

Two  hundred  pounds  per  acre  of  nitrogen  was  applied  on  all  experi- 
ments each  year  prior  to  plowing.  An  additional  ten  pounds  per  acre  of 
nitrogen  was  applied  beside  two  of  the  four  corn  rows  of  all  treatments  in 
each  plot  in  1963  on  both  the  Crosby  soil  location  and  on  the  Fincastle 
and  Russell  soils  location.  Rates  of  broadcast  phosphorus  and  potassium 
fertilizer  were  applied  in  only  one  year,  1963,  on  the  Crosby  soil  location. 
All  broadcast  phosphorus  and  potassium  fertilizers  were  applied  in  the 
spring,  half  before  plowing  and  half  after.  On  the  Martinsville  and 
Russell  phosphorus  fertility  experiment,  598  pounds  per  acre  of  potassium 
was  broadcast.  On  the  potassium  fertility  experiment  on  the  same  loca- 
tion, 120  pounds  per  acre  of  phosphorus  was  broadcast  and  40  pounds 
per  acre  of  P  was  used  in  the  row.  In  all  experiments  where  row  fertilizer 
was  used,  it  was  applied  approximately  two  inches  horizontally  away 
from  the  seed  at  planting. 

Aldrin  granules  for  controlling  soil  insects  were  broadcast  on  plowed 
ground  and  disked  in  immediately  prior  to  planting  on  all  experiments 
conducted  in  1964.  Broadcast  atrazine  spray  after  planting  to  control 
weeds  was  applied  to  both  Martinsville  and  Russell  soils  experiments  in 
1964  and  to  the  Crosby  experiment  in  1965.  Conventional  cultivation  and 
hand  hoeing  were  used  on  all  experiments  as  needed  to  control  weeds. 

Funks  G-96  and  Indiana  678  corn  hybrids  were  used  for  seed  on  all 
experiments  in  1963  and  in  1964  respectively.  Pfisters  Associated  Growers 
Sx29  was  used  on  the  Crosby  location  in  1965.

Stands  per  acre  counted  at  harvest  were  approximately  16,200  on 
the  Crosby  location  in  1963,  19,800  in  1964,  and  16,300  in  1965.  Final 
stands  on  the  Martinsville  and  Russell  experiments  in  1964  were  approxi- 
mately 16,000  plants  per  acre.  On  the  Fincastle  and  Russell  location  final 
stands  were  approximately  16,500  plants  per  acre. 

Dates  of  planting  on  the  Crosby  location  were  June  4  in  1963,  May 
22  in  1964,  and  May  13  in  1965.  The  Martinsville  and  Russell  soils  location 
was  planted  May  29,  1964.  The  Fincastle  and  Russell  soils  location  was 
planted  May  24,  1963. 

Height  measurements  were  made  on  the  tallest  extension  of  leaves 
of  each  of  10  or  more  plants  within  the  harvest  area  of  each  plot  of  all 
replications. 

Composite  corn  ear  leaf  samples  of  15  or  more  leaves  per  treatment 
taken  at  the  green  silk  stage,  were  ground  and  then  sent  to  the  Depart- 
ment of  Agronomy,  Ohio  Agricultural  Research  and  Development  Center, 
Wooster,  Ohio,  for  analyses. 

For  yield  determination,  ear  corn  was  hand  harvested.  Weights  and 
moisture  percentages  in  the  grain  were  determined,  and  yields  were 
calculated  using  Remmenga's  tables   (3). 

Results  and  Discussion 

These  experimental  sites  were  selected  because  they  had  low  or  very 
low  soil  test  values  for  the  fertilizer  nutrient  being  studied,  and  they 
represented  important  soil  types  in  Indiana   (Table  1).

Height  of  corn  increased  3.3  to  7.9  inches  as  phosphorus  rates 
increased  on  the  Fincastle  and  Russell  soils  location  in  1963  (Table  2). 
There  was  no  significant  differences  in  height  between  the  Fincastle  soil 
(Replication  I)  and  the  Russell  soil  (Replications  II  and  III). 


Soil  Science  439 

Yields  on  the  Fincastle  replication  were  11  to  12  bushels  per  acre 
higher  than  the  yields  on  the  two  Russell  replications.  The  probability 
was  more  than  99  to  1  that  this  difference  was  real  and  was  not  due  to 
chance  alone.  Yields  of  corn  grain  were  significantly  increased  4.5  to 
15.1  bushels  per  acre  as  rates  of  phosphorus  fertilization  increased  in  the 
same  experiment  (Table  3).   There  was  also  a  trend  toward  higher  phos-

phosphorus  in  the  ear  leaf  was  in  the  low  range  as  denned  by  the  Purdue 
Plant  and  Soil  Anailysis  Laboratory  (4).  The  response  to  phosphorus  was 
large  for  the  first  increment  of  fertilizer  as  might  have  been  expected 
from  the  very  low  soil  test  value  for  phosphorus. 

In  the  same  experiment  there  was  no  increase  in  height  of  corn  in 
relation  to  rates  of  potassium  fertilization   (Table  2),  but  there  was  a 


440  Indiana  Academy  of  Science 

significant  increase  in  yield  (Table  3).  Where  phosphorus  was  applied 
and  potassium  was  not,  corn  ear  leaf  content  of  potassium  was  in  the 
low  range  (Table  4).  Evidently,  soil  potassium  available  to  corn  was  not 
low  enough  to  influence  height  31  days  after  planting,  but  it  did  influence 
the  plants  later  in  the  season. 

After  1963,  it  was  impossible  to  obtain  additional  data  from  this 
Fincastle  and  Russell  soils  experiment.  After  the  death  of  the  owner, 
H.  Byers,  the  new  owner  would  not  lease  the  land  for  agricultural 
research  purposes. 

On  the  Martinsville  and  Russell  soils  location  height  of  corn  46  days 
after  planting  was  significantly  increased  as  rates  of  both  row  and 
broadcast  phosphorus  increased   (Table  5).    Twenty  pounds  per  acre  of

row  phosphorus  resulted  in  the  same  height  of  corn  as  120  pounds  per 
acre  of  broadcast  P,  or  a  1  to  6  efficiency  ratio.  Drouth  was  so  severe 
at  this  location  in  July  and  August,  1964,  that  yields  ranged  from  2  to  87 
bushels  per  acre,  and  they  were  not  significantly  related  to  treatment. 
This  great  range  in  yields  reflected  a  large  difference  in  available  soil 
moisture. 

Height  of  corn  48  days  after  planting  was  significantly  reduced  at  the 
high  rates  of  broadcast  potassium  on  the  Martinsville  and  Russell  soils 
location  (Table  6).  It  is  thought  that  high  soluble  salts  in  the  soil  and 
relatively  dry  soils  reduced  rate  of  growth  in  this  drouthy  season.  Yields 
of  corn  grain  were  very  low,  ranging  from  2  to  27  bushels  per  acre,  and 
they  were  not  significantly  related  to  potassium  treatment. 

On  both  of  these  experiments  on  the  Martinsville  and  Russell  soils 
there  was  great  variation  in  initial  soil  test  values  from  individual  plots. 
As  a  result  of  this  variation  and  the  yield  variation,  particularly  in  the 
phosphorus  experiment,  the  location  was  discontinued.

On  Crosby  soil  in  a  three-year  period  (1963-1965)  height  and  yields 
of  corn  were  significantly  increased  as  phosphorus  fertilization  increased, 
but  height  and  yields  were  not  meaningfully  related  to  potassium  fertiliza- 
tion even  though  initial  soil  test  levels  for  phosphorus  and  potassium  were 
very  low  and  low  respectively  (Tables  7  and  8).  Analyses  of  the  ear  leaf

of  the  1963  crop  indicated  that  phosphorus  was  low  when  none  was 
applied,  and  potassium  was  deficient  (4)  when  none  was  applied  (Table 
9).  Higher  yield  levels  might  have  resulted  in  yield  differences  related 
to  potassium  fertilization.  However,  on  this  Crosby  soil  in  this  1963-1965 
period  soil  test  levels  did  predict  response  to  phosphorus  fertilizer,  but 
they  did  not  predict  response  to  potassium  fertilizer.

Summary 

Average  yields  of  corn  on  one  replication  of  a  Fincastle  soil  were  11 
more  bushels  per  acre  higher  than  those  on  two  replications  of  a  Russell 
soil  of  a  fertilizer  experiment.  On  this  experiment  and  also  on  a  similar 
experiment  on  Crosby  soil,  height  of  corn,  yield  of  grain  and  phosphorus 
composition  of  corn  ear  leaves  were  increased  as  rates  of  phosphorus  fer- 
tilization increased.  On  a  third  location  on  Russell  and  Martinsville  soils, 
height    of    corn    was    increased,    but    yields    were    not    increased    in    a

drouthy  season,  as  rates  of  phosphorus  fertilization  increased.   The  initial 
phosphorus  soil  test  levels  of  all  three  locations  were  low  or  very  low. 

Potassium  fertilization  increased  yield  and  potassium  composition 
of  ear  leaf  of  corn  on  the  Fincastle  and  Russell  soils  location  testing  low 
in  potassium.  High  rates  of  broadcast  potassium  fertilizer  on  a  Martins- 
ville and  Russell  soils  location  reduced  corn  height  in  a  very  dry  year. 
On  a  Crosby  soil  there  was  no  height  or  yield  response  of  corn  to 
potassium  fertilization  over  a  three-year  period  even  though  the  initial 
soil  test  level  for  potassium  was  low.

ABSTRACTS 

Temperature  Preferences  in  the  Eastern  Garter  Snake 
(Thamnophis  sirtalis  sirtalis).  David  C.  Kramer,  Ball  State  University. — 
Nine  Eastern  Garter  Snakes  were  maintained  in  a  thermal  gradient  box 
with  a  controlled  photoperiod  for  54  days.  The  snakes  were  observed 
twice  daily  and  the  environmental  temperature  selected  by  each  was 
recorded.  After  20  days'  exposure  to  a  daily  photoperiod  of  14  hours,  the 
snakes  were  exposed  to  a  photoperiod  of  10  hours  for  34  additional 
days,  but  no  change  in  temperature  preferences  was  noted.  The  average 
temperature  selected  by  all  of  the  snakes  for  the  entire  test  period 
was  22.9  degrees  C.  However,  there  was  a  consistent  tendency  for 
all  snakes  to  select  a  slightly  warmer  temperature  in  the  afternoon  than 
in  the  morning.  The  average  difference  between  the  preferred  morning 
and  afternoon  temperatures  was  approximately  2.0  degrees  C. 

Relationship  between  Emergence  Rhythm  and  Metabolic  Rhythm  in 
Drosophila  melanogaster.  William  J.  Brett,  Indiana  State  University. — 
A  population  of  wild  type  Drosophila  melanogaster  was  maintained  in  a 
twelve-hour-light — twelve-hour-dark  cycle  with  light  onset  at  9:00  a.m. 
Females  were  allowed  to  oviposit  over  a  24-hour  period  to  provide  com- 
parably aged  samples.  The  oxygen  consumption  for  a  number  of  pupae 
obtained  from  each  sample  was  determined  for  a  one-hour  period  at 
three-hour  intervals  over  a  48-72  hours  period.  The  remaining  pupae  in 
each  sample  were  permitted  to  emerge  and  number  of  adults  determined 
at  three-hour  intervals.  The  peak  for  emergence  occurred  at  12:00 
noon.  Oxygen  consumption  exhibited  a  major  peak  at  10:00  p.m.  and 
a  minor  peak  at  1:00  p.m.  With  the  exception  of  the  minor  peak  the 
two  curves  were  almost  mirror  images  of  one  another.  These  results 
suggest  that  emergence  may  actually  occur  during  a  metabolic-low. 

The  Effects  of  Chicken  Luteinizing  Hormone  on  the  Pullet  Ovary.  John 
M.  Burns,  Indiana  University. — Mammalian  luteinizing  hormone  (LH) 
has  very  little  effect  on  the  immature  chicken  ovary  and,  therefore,  a 
study  was  initiated  to  determine  the  response  of  the  pullet  ovary  to 
chicken  LH.  As  no  purified  samples  of  chicken  LH  were  available  it  was 
necessary  to  develop  a  method  for  obtaining  LH  activity  from  chicken 
pituitary  glands  without  interference  from  the  pituitary  follicle  stimulat- 
ing hormone  (FSH).  This  was  done  by  treating  chicken  pituitary  glands 
with  neuraminidase  which  inactivated  the  FSH.  The  administration  of 
chicken  LH  to  immature  chickens  resulted  in: 

(1)  a  significant  32P  uptake  by  the  ovary  in  15  minutes. 

(2)  an  increase  in  32P  incorporation  into  the  RNA  fraction  of  the 
ovary.

Tracheal  Mucous  Velocities  in  the  Rabbit,  Dog,  and  Rat.  Andrew  W. 
Gruenholz  and  Henry  Tamar,  Indiana  State  University. — The  tracheas 
of  24  Dutch  rabbits,  16  dogs,  and  6  Charles  River  albino  rats  were  excised, 
opened,  and  immersed  in  oxygenated  Tyrode's  solution.  The  transit  time 
of  a  1  mm.  platinum  disc  over  5  mm.  of  pseudo-stratified  ciliated  epi- 
thelium was  determined  at  39°  C  for  the  rabbits  and  dogs,  and  at 
37°  C  for  the  rats.  The  insulated  test  chamber  was  leveled,  extraneous 
heat  was  eliminated,  and  a  15-minute  adaptation  period  was  allowed. 
Transit  times  for  the  rabbit  and  dog  remained  constant  for  one  hour. 
The  mean  mucous-flow  velocity  was  0.292  mm. /second  for  the  rabbit, 
0.585  mm. /second  for  the  dog,  and  0.167  mm. /second  for  the  rat.  The 
difference  between  the  rabbit  and  dog  values  was  significant  at  the  0.1 
level.  Solutions  of  0.2M  and  0.25M  NaCl  depressed  ciliary  activity  in 
the  dog  respectively  1.9  and  1.68  times  more  than  the  equivalent  concen- 
trations of  KC1.  In  the  rabbit  as  well  0.2M  NaCl  was  more  depressant 
than  0.2M  KC1.  The  trachea  of  the  rabbit  exhibited  rhythmic  contractions 
of  its  blood  vessels  following  immersion  in  0.2M  KC1. 

Studies    on    the    Growth    Rate    of    the    Juvenile    Pilot    Black    Snake 

(Elaphe  obsoleta).  Robert  E.  Geyer,  Jr.  and  William  B.  Hopp,  Indiana 
State  University. — Fifteen  pilot  black  snakes  were  hatched  from  eggs  in 
the  laboratory.  These  snakes  were  individually  housed  and  divided  into 
five  groups  of  three  snakes  per  group.  Each  snake  in  group  I  received 
1  cc  of  food  per  week,  group  II,  1.5  cc  per  week,  group  III,  2.0  cc  per 
week,  group  IV,  2.5  cc  per  week,  and  group  V,  3.0  cc  per  week.  The 
snakes  were  force-fed  a  mixture  of  strained  baby  foods  consisting  of  beef, 
beef  liver,  and  veal  by  the  syringe-catheter  technique.  Although  several 
measurements  were  taken,  weight  gain  was  found  to  be  the  most  reliable 
basis  for  determining  growth.  Weekly  recordings  of  weight  were  made 
during  the  12-week  period  this  experiment  was  conducted. 

At  the  end  of  12  weeks  the  snakes  in  group  I  had  gained  an  average 
of  1.93  grams,  group  II,  2.80  grams,  group  III,  3.33  grams,  group  IV, 
4.77  grams,  and  group  V,  6.25  grams.  The  average  gain  in  weight  per 
week  for  each  group  was  0.16,  0.23,  0.28,  0.40,  and  0.52,  respectively. 


Rabies  in  Indiana  Bats

Abstract 

A  total  of  626  bats  routinely  submitted  to  the  Indiana  State  Board  of 
Health  from  1965  to  1968  was  examined  for  rabies  using-  the  fluorescent 
antibody  test  and  sometimes  the  mouse  test.  Of  these  42,  or  6.7%,  were 
rabid.  Twenty-four  of  364  big  brown  bats,  Eptesicus  fuscus,  were  rabid  as 
were  11  of  152  red  bats,  Lasiurus,  borealis.  Bat  rabies  was  more  common  in 
the  southern  than  in  the  northern  portions  of  the  state,  and  was  more 
common  in  the  summer  and  fall  than  at  other  times.  There  were  two  apparent 
outbreaks  of  rabies  in  Indiana  in  bats  in  1967,  one  in  Eptesicus  fuscus  in 
Jefferson  County  and  one  in  Lasiurus  borealis  in  Vanderburgh  County.  Bat 
rabies  has  been  reported  in  a  total  of  17  Indiana  counties.  There  appears 
to  be  no  positive  correlation  in  Indiana  between  rabies  in  bats  and  rabies  in 
other  species.  A  total  of  133  big  brown  bats  was  collected  in  "normal  wild" 
populations  of  Eptesicus  in  Jefferson  County  at  the  height  of  the  1967  rabies 
outbreak,  but  all  proved   negative  for  rabies. 

Introduction 

Rabies  was  first  found  in  a  United  States  bat  in  1953  when  a  Florida 
Yellow  bat  was  killed  while  attacking  a  seven-year-old  boy  (7).  Rabies 
has  now  been  reported  in  all  of  the  48  contiguous  states;  Rhode  Island 
became  the  last  on  June  12,  1967  (1).  The  disease  has  now  been  found 
in  at  least  20  species  of  bats. 

Some  summarized  incidence  figures  for  bat  species  in  which  large 
numbers  of  bats  have  been  examined  in  Florida  (5,  7),  Texas  (6),  south- 
western United  States  (2),  southern  New  England  (3)  and  Illinois 
(4,  8)   are:

Illinois  is  the  only  midwestern  state  in  which  there  have  been  exten- 
sive surveys  for  bat  rabies.  A  total  of  652  bats  was  examined  (8,  4)  and 
none  were  found  to  be  rabid.  Unfortunately  only  12  were  red  bats,  the 
species  in  which  the  highest  incidence  of  rabies  generally  occurs.  Of  the 
remainder,  504  were  Myotis,  the  genus  which  generally  has  the  lowest 
incidence  of  rabies.  Fifty-five  were  Eptesicus,  65  were  Pipistrellus,  8 
were  Plecotus  and  8  were  Lasionycteris  noctivagans. 

Before  the  present  study  there  were  four  confirmd  cases  of  bat 
rabies  in  Indiana.  A  red  bat,  Lasiurus  borealis,  taken  in  Tippecanoe 
County,  September  5,  1960,  was  rabid,  as  was  a  silver-haired  bat, 
Lasionycterius  noctivagans,  taken  September  12-13,  1960,  in  Montgomery 
County.  Thirty-three  additional  bats,  unidentified,  taken  in  1960,  were 
not  rabid.  None  were  examined  from  1961  through  1963,  but  in  1964,  37 
unidentified  bats  were  found  to  be  negative  for  rabies.  Two  rabid  speci- 
mens were  found  in  1965  among  70  unidentified  bats.  One  of  the  rabid 
bats  was  from  Delaware  County  and  one  from  Monroe  County. 

The  present  study  was  initiated  in  1965  to  determine: 

a.  the  distribution  and  incidence  of  rabies  in  Indiana  bats 

b.  the  relationship  between  rabies  in  bats  and  rabies  in  other 
species  of  mammals  in  Indiana 

c.  the  relation  between  incidence  of  rabies  in  bats  turned  in  by 
Indiana  citizens  to  the  Indiana  State  Board  of  Health  and 
rabies  in  wild-taken  bats. 

Materials  and  Methods 

The  brains  of  all  bats  submitted  to  the  Indiana  State  Board  of 
Health  were  examined  directly  for  Negri  bodies  and  by  the  fluorescent 
antibody  method.  Brain  material  from  many  was  injected  into  white  mice 
as  a  further  test.  These  bats  came  from  throughout  the  state.  Starting 
in  1966,  all  bats  submitted  to  the  Indiana  State  Board  of  Health  were 
identified  by  the  senior  author. 

Many  bats  came  from  a  small  number  of  counties.  In  two  counties, 
Jefferson  and  Vanderburgh,  there  were  widely  publicized  bat  rabies 
scares  in  1967;  these  are  the  counties  from  which  we  have  examined  the 
largest  numbers  of  specimens.  Three  other  counties  from  which  large 
numbers  of  bats  have  been  examined  are  Marion,  Johnson,  and  St.  Joseph, 
all  of  which  have  yielded  rabid  bats.  Bat  rabies  in  Vanderburgh  County 
was  chiefly  in  red  bats,  Lasiurus  borealis,  while  in  Jefferson  County  it 
was  primarily  in  big  brown  bats,  Eptesicus  fuscus.  Efforts  were  made  to 
obtain  large  numbers  of  bats  from  "normal  wild  colonies"  of  Eptesicus  in 
Jefferson  County  on  July  21,  1967,  at  the  peak  of  the  outbreak.  A  total 
of  97  bats  was  collected  that  day  by  the  senior  author  and  Robert  Kerr, 
the  Jefferson  County  Sanitarian.  Later  samples  by  Mr.  Kerr  increased 
the  total  of  bats  from  the  "wild"  populations  to  133. 

Information  on  rabies  in  species  other  than  bats  was  acquired  from 
the  files  of  the  Indiana  State  Board  of  Health.  This  information  was 
compared  with  the  bat  rabies  information.

A  total  of  759  bats  was  examined  during  this  study,  626  of  them 
submitted  to  the  Indiana  State  Board  of  Health  by  citizens,  physicians, 
veterinarians,  and  law  or  health  officials  for  routine  rabies  examination, 
and  133  from  the  Jefferson  County  "wild  sample." 

Species  of  bats  infected 

Two  of  the  species  collected  in  small  numbers,  Pipistrellus  subflavus 
and  Lasiurus  cinereus,  had  the  highest  incidence  of  rabies  of  any  of  the 
bats  taken  during  this  study  (Table  1),  but  this  may  be  chance.  Only  16 
individuals  of  each  species  were  taken.

The  two  most  common  bats  of  Indiana  appear  to  be  Lasiurus  borealis, 
the  red  bat,  and  Eptesicus  fuscus,  the  big  brown  bat.  Lasiurus  borealis 
is  a  solitary  species,  but  is  quite  common,  especially  in  southern  Indiana. 
This  species  would  appear  to  be  the  most  commonly  infected  of  the  United 
States  bats  that  have  been  studied.  In  Indiana,  7.2%  of  the  red  bats 
submitted  by  citizens  to  the  State  Board  of  Health  were  rabid  (Table  1). 
Eptesicus  fuscus  is  most  often  directly  associated  with  human  beings, 
often  forming  large  colonies  in  barns,  houses  and  other  buildings.  For 
this  reason,  and  since  large  numbers  of  Eptesicus  have  not  been  examined 
for  rabies,  data  on  this  species  are  particularly  desirable.  The  rate  of 
rabies  infection  in  Eptesicus,  6.6%,  was  slightly  lower  than  in  red  bats. 

In  Indiana,  the  major  cave  bats  are  species  of  Myotis,  of  which  6Q 
specimens  were  examined,  one  (1.5%)  being  rabid. 

Overall,  42  of  626,  or  6.7%  of  the  bats  submitted  to  the  Indiana 
State  Board  of  Health  were  rabid.

Geographic  distribution  of  bat  rabies  in  Indiana 

During  the  present  study  (Table  2),  rabies  was  found  in  bats  from 
fourteen  counties:  Daviess,  Dearborn,  Fayette,  Gibson,  Greene,  Hendricks,

*  Bat  rabies  found  before  initiation  of  present  study. 


During  this  study,  most  of  the  rabid  bats  were  from  southern  Indi- 
ana. The  state  was  divided  roughly  into  thirds,  from  north  to  south. 
Three  of  97,  or  3.0%  of  the  bats  from  the  northern  third  of  the  state  were 
rabid,  9  of  221,  or  4.1%  from  the  central  third,  and  30  of  308  or  9.7%, 
from  the  southern  third  of  the  state  were  rabid.  This  difference  was 
significant  (Chi-square  =  9.68**,  2  df).  However,  the  two  major  bat 
rabies  counties,  Jefferson  and  Vanderburgh,  are  in  the  southern  third. 
Excluding  information  from  those  two  counties,  seven  of  81  bats,  or 
8.6%,  were  rabid  from  the  southern  third  of  the  state,  thus  still  consti- 
tuting a  greater  percentage  infection  than  in  the  north  or  central 
counties,  but  this  difference  was  not  significant  (Chi-square  =  3.10,  1  df).

Time  of  year  of  infection 

Rabies  infections  in  bats  were  summarized  by  time  of  year  of  occur- 
rence (Table  3).  Most  rabid  bats  were  taken  in  the  summer,  but  these 
were  also  the  months  in  which  most  of  the  bats  were  taken.  Of  429  bats 
taken  in  the  summer  (June- August),  32,  or,  7.5%  were  rabid,  while  in

the  fall  (September  to  November)  7  of  80,  or  8.8%  were  rabid,  in  the 

winter  (December  to  February),  0  of  33,  and  in  the  spring   (March  to 

May),  3  of  84,  or  3.6%  were  rabid.  Thus,  bat  rabies  in  Indiana  has  been 
occurring  in  the  summer  and  fall. 

Change  in  rate  of  occurrence  of  disease  through  years  of  study 

The  overall  rate  of  infection  in  1966  was  8.6%  (10  of  135  infected); 
in  1967  it  was  7.3%  (24  of  328),  and  in  1968  it  was  4.4%  or  8  of  183. 
Thus  it  would  not  appear  that  the  disease  has  been  increasing  in  Indiana 
bats  over  the  past  three  years.  These  data  would  suggest  a  decrease 
over  the  period,  but  the  observed  difference  was  not  significant  (Chi- 
square  =  2.33,  2  df). 


Marion,  Johnson,  St.  Joseph,  Vanderburgh,  and  Jefferson  Counties 

Five  counties  were  studied  intensively  (Table  4).  There  were  rabies 
"outbreaks"  in  1967  in  big  brown  bats  in  Jefferson  County  and  in  red 
bats   in   Vanderburgh    County.     Both    outbreaks    were    publicized,    hence

numerous  bats  were  submitted  to  health  authorities,  and  we  have  rather 
large  citizen  samples  from  these  counties.  Also  we  have  a  rather  large 
citizen  sample  from  Marion,  Johnson,  and  St.  Joseph  Counties.  These  are 
counties  in  which  rabies  is  present  but  in  which  there  was  no  major 
publicity. 

Jefferson  County  is  in  southeastern  Indiana.  In  1967,  11  of  93  bats, 
or  11.8%  were  found  to  be  rabid.  In  1968,  2  of  36,  or  5.5%  were  rabid. 
All  but  one  of  the  rabid  bats  from  this  county  were  big  brown  bats,  and 
all  were  from  the  city  of  Madison.  None  of  the  16  red  bats,  Lasiurus 
borealis,  taken  there  were  rabid. 

In  Vanderburgh  County,  seven  of  the  ten  rabid  bats  were  red  bats, 
Lasiurus   borealis,  but   only   thirteen   big   brown   bats,  Eptesicus,  were

taken,  of  which  one  was  rabid.   The  total  number  of  bats  examined  from 
Vanderburgh  County  was  95. 

Thus  the  bat  rabies  situation  was  much  different  in  Jefferson  and 
Vanderburgh  Counties,  with  red  bats  being  the  main  species  infected  in 
Vanderburgh  County,  and  big  brown  bats  being  the  main  species  infected 
in  Jefferson  County.  Hopefully  more  red  bats  from  Jefferson  County  and 
more  big  brown  bats  from  Vanderburgh  County  will  be  taken  in  the 
future. 

Marion,  Johnson,  and  St.  Joseph  Counties  were  counties  in  which  bat 
rabies  has  been  found,  but  where  this  fact  apparently  was  not  widely 
publicized,  thus  there  was  no  major  effort  by  citizens  to  turn  in  bats. 
However,  large  numbers  of  bats  were  submitted  from  these  counties,  and 
data  from  them,  taken  collectively,  was  considered  as  a  control,  for  com- 
parison with  data  from  the  two  counties  with  publicized  rabies.  In  the 
three  counties,  eight  of  160  bats,  or  5.00%  were  rabid,  as  compared  to  23 
of  227  (10.1%)  in  Jefferson  and  Vanderburgh  Counties.  This  difference 
was  not  significant  (Chi-square  =  3.35,  1  df). 

Relation  between  Rabies  in  the  "Citizen  Sample"  and  the  "Wild  Sample" 

It  was  hypothesized  that  if  the  bats  were  being  found  by  the  citizens 
because  they  were  "sick"  from  rabies,  then  the  incidence  of  rabies  should 
be  higher  in  the  citizen  sample  than  in  the  wild  simple.  On  the  other 
hand,  if  the  bats  were  not  affected  by  the  virus,  then  rabies  should  occur 
in  the  wild  sample  and  the  citizen  sample  at  about  the  same  rate.  (In 
this  latter  case,  they  could  be  acting  as  carriers  of  rabies  in  that  they 
harbor  the  virus,  yet  do  not  get  the  disease  themselves,  as  has  been 
suggested.  If  this  were  the  case  then  bats  might  constitute  a  natural 
source  of  infection  from  which  other  species  might  contract  the  disease.) 

For  comparison  with  the  citizen  sample,  133  bats  were  collected  from 
seven  colonies  during  the  height  of  the  1967  rabies  outbreak  in  Jefferson 
County  (97  in  six  colonies  in  the  city  of  Madison,  some  in  the  same 
buildings  from  which  rabid  bats  had  originated,  and  36  bats  from  a 
locality  15  miles  southwest  of  Madison.)  None  of  these  bats  was  rabid. 
The  above  hypothesis  was  not  supported.  However,  it  is  possible  that 
rabies  is  found  only  in  certain  colonies,  and  that  the  wrong  colonies  were 
sampled.  The  possibility  that  bats  leave  the  colonies  when  they 
become  rabid,  and  that  they  are  more  likely  to  come  into  contact  with 
humans,  when  rabid,  seems  a  probable  explanation  of  the  data  at  this 
time. 

Hopefully,  future  laboratory  studies  can  be  undertaken  to  determine 
whether  individual  bats  become  sick  or  die  when  they  contract  the  disease, 
and  if  so,  how  long  this  takes. 

Relation  of  Rabies  in  Bats  to  Rabies  in  Other  Species  in  Indiana 

If  there  is  a  relationship  between  rabies  in  bats  and  rabies  in  other 
species  of  mammals  as  has  been  suggested,  then  it  would  seem  that 
there  should  be  a  positive  association  between  areas  with  bat  rabies  and 


Zoology  455 

those  with  rabies  in  other  spec-ies.  If  there  is  no  such  relationship,  then 
it  would  seem  that  incidence  of  rabies  in  other  species  would  be  about 
the  same  in  counties  with  bat  rabies  and  counties  without  bat  rabies. 

Since  the  greatest  number  of  cases  of  bat  rabies  occurred  in  1967,  and 
since  the  Indiana  State  Board  of  Health  has  summarized  information 
concerning  rabies  in  all  species  in  1967,  data  from  that  year  were 
examined  for  relationship  between  bat  rabies  and  rabies  in  other  species. 

In  the  six  counties  with  bat  rabies  in  1967,  a  total  of  949  individuals 
other  than  bats  were  examined.  Five  of  these,  or  0.5%  were  found  to  be 
rabid.  From  all  other  counties,  a  total  of  2369  individuals  was  examined, 
of  which  58,  or  2.45%  were  rabid. 

This  would  lead  one  to  believe  that,  in  Indiana,  there  is  no  positive 
correlation  between  rabies  in  bats  and  rabies  in  other  species.  In  fact, 
one  could  draw  the  reverse  conclusion,  that  there  is  a  negative  correla- 
tion between  bat  rabies  and  rabies  in  other  species,  since  significantly 
more  rabid  animals  were  found  in  other  species  in  those  counties  not 
reporting  bat  rabies  than  in  those  with  bat  rabies  in  1967  (Chi- 
square  —  13.18,  1  df).  Unfortunately,  the  counties  in  which  numbers  of 
bats  have  been  examined  are  not  always  the  same  counties  in  which 
adequate  numbers  of  other  species  have  been  examined. 

Information  from  some  of  the  critical  counties  is  as  follows:  in 
Jefferson  County  rabies  was  not  found  in  the  27  other  mammals  examined 
in  1967;  in  Vanderburgh  County,  three  of  193  other  mammals  examined 
were  rabid  (1.55%).  In  Marion  County,  in  which  3  of  67  bats  over  the 
past  three  years  have  proved  rabid,  no  rabies  cases  were  reported  in  537 
mammals  examined  in  1967.  Other  than  Vanderburgh,  the  major  rabies 
counties  for  other  species  in  1967  were  Daviess,  Knox,  Lake,  and  Shelby, 
each  having  at  least  three  rabid  animals  other  than  bats  in  1967.  Thus, 
it  would  be  instructive  to  examine  large  numbers  of  bats  from  these 
counties,  but  a  total  of  only  five  was  received  in  1967. 

Twelve  of  168  bats  (7.1%)  v/ere  rabid  from  the  44  counties  with 
rabies  in  other  species  in  1967,  while  in  the  counties  not  reporting  rabies 
in  other  species,  22  of  160  bats  (13.8%)  were  rabid,  but  this  difference 
was  not  significant  (Chi-square  =  3.44,  1  df). 

As  a  further  test,  the  data  from  the  counties  adjoining  the  two  major 
bat  rabies  counties,  Jefferson  and  Vanderburgh,  were  summarized  and 
compared  to  the  data  from  the  remainder  of  southern  Indiana.  In 
Vanderburgh,  Posey,  Gibson,  Pike,  and  Warrick  Counties,  243  individuals 
other  than  bats  were  examined,  of  which  3  or  1.23%  were  rabid.  In  Jef- 
ferson, Scott,  Clark,  Jennings,  Ripley,  Dearborn,  Ohio,  and  Switzerland 
Counties,  a  total  of  188  individuals  of  other  species  were  taken,  of  which 
8,  or  4.2%  were  rabid.  In  the  remaining  southern  Indiana  counties,  379 
individuals  other  than  bats  were  examined,  of  which  24,  or  6.3%  were 
rabid,  thus  again  indicating  lack  of  association  or  even  negative  associa- 
tion between  bat  rabies  and  rabies  in  other  species. 


456  Indiana  Academy  of  Science 

Although  important  data  are  lacking,  one  can  only  conclude  that 
there  is  no  positive  correlation  between  bat  rabies  and  rabies  in  other 
species  in  Indiana. 

Thanks  to  Mr.  Robert  Kerr,  the  Jefferson  County  Sanitarian,  we 
have  relatively  complete  information  concerning  the  status  of  many  of 
the  Jefferson  County  bats  when  collected.  Of  109  bats  collected  17,  or 
15.6%  were  dead  when  taken.  Among  the  96  non-rabid  bats,  14  or  14.6% 
were  dead,  while  among  the  13  rabid  bats,  3  or  23%  were  dead. 

It  is  recognized  that  there  are  certain  problems  inherent  in  data  of 
the  kind  that  have  been  collected  during  this  study.  For  example,  in  the 
comparison  between  bat  rabies  and  rabies  in  other  species,  most  of  the 
bats  were  from  cities,  while  many  of  the  specimens  of  wild  species  may 
be  from  rural  areas,  but  there  is  no  way  to  check  this.  We  have  no  actual 
or  relative  information  concerning  the  size  of  the  bat  populations  in  the 
various  counties.  Data  of  this  sort  would  be  very  valuable.  Most 
important,  none  of  the  data  were  collected  in  a  truly  random  fashion.

Preference  for  Toxic  and  Non-toxic 
Artificial  Sweeteners  in  Rodents1 

Mahlon  W.  Wagners  and  W.  C.  Gunther 
Valparaiso  University 

Abstract 

Four  species  of  deer  mice  (Peromyscus)  were  given  choices  of  glucose 
and  three  artificial  sweeteners:  sodium  saccharin  and  sodium  or  calcium 
cyclamate.  Preferences  for  glucose  vs  saccharin  were  based  on  relative 
sweetness,  with  the  sweeter  of  a  pair  being-  chosen.  However,  Ss  preferred 
glucose  to  the  cyclamates  regardless  of  relative  sweetness.  Evidence  is 
presented  to  suggest  that  aversion  to  the  cyclamates  may  be  based  either 
on  noxious  stimuli  associated  with  ingestion  (according  to  recent  toxicity 
studies  of  cyclamates)  or  on  taste  qualities  in  addition  to  sweetness  that 
may  be  present  in  the  cyclamates.  Therefore,  learning  and  physiological 
factors  as  well  as  taste  are  implicated  in  food  preferences. 

Introduction 

Artificial  sweeteners  have  been  available  as  sugar  substitutes  for 
diabetics  and  dieters  for  many  years.  While  saccharin  has  a  bitter  after- 
taste to  humans,  it  has  been  used  extensively  as  an  effective  reward  in 
many  animal  learning  studies  since  1933  (5).  Squirrel  monkeys,  however, 
do  not  prefer  saccharin  (2).  New  artificial  sweeteners,  the  cyclamate 
salts,  were  introduced  in  1950  and  rapidly  surpassed  saccharin  in  popu- 
larity, accounting  for  sales  of  $25  million  in  1961.  Perhaps  because  of  the 
newness  of  the  cyclamates,  few  studies  with  animals  have  been  reported: 
Murray  et  al.  (8)  found  rats  to  prefer  water  to  all  concentrations  of  Na 
cyclamate,  but  Smith  and  Ross  (15)  found  C57  black  mice  to  prefer 
maximally  a  1%  Na  cyclamate  solution  to  water. 

The  basis  for  sweet  preference  is  usually  ascribed  to  innate  and /or 
learning  factors.  Glucose  is  sweet  and  directly  utilizable  for  energy  by 
the  cells.  These  sweet  preferences  can  be  "unlearned"  when  paired  with 
noxious  stimuli  (12).  Nees  and  Derse  (11)  and  Japanese  researchers 
recently  reported  that  cyclamates  fed  to  rats  and  mice  resulted  in  infer- 
tility, laxative  effects  and  fetal  deaths.  It  may  be  hypothesized  that  these 
toxic  effects  would  result  in  a  preference  change  similar  to  that  reported 
above  when  sweet  compounds  were  paired  with  noxious  stimuli,  although 
the  chemical  need  not  be  ingested  in  sufficient  quantities  to  produce  toxic 
effects,  since  Nachman  (9,  10)  has  shown  laboratory  rats  to  avoid  LiCl 
once  having  experienced  ill  effects  and  Fregly  (3)  has  found  adult  rats 
to  avoid  LiCl  although  never  having  experienced  toxic  effects.  Gunther 
(1),  on  the  other  hand,  finds  that  lactose  fed  to  early  posthatching  chicks 
resulted  in  many  deaths  and  that  apparently  there  was  no  preference 
change  to  the  less  noxious  stimuli  available.  Kare  (6),  however,  reports 
that  chicks  and  adult  chickens  are  indifferent  to  lactose,  suggesting  an 
inability  to  discriminate  a  lactose  solution  from  water.

It  was  the  purpose  of  this  study  to  examine  the  preferences  of  sev- 
eral rodent  species  for  artificial  sweeteners  either  known  to  be  non-toxic 
or  suspected  of  having  toxic  effects. 

Materials  and  Methods 

Four  species  of  deer  mice — males  and  females  of  Peromyscus 
leucopus  (N=7  and  4,  mean  weight  23.5  and  21.6  gm.),  Peromyscus 
eremicus  (N=4  and  3,  mean  weight  18.5  and  17.9  gm.),  Peromyscus 
maniculatus  bairdii  (N=2  and  3,  mean  weight  20.4  and  15.5  gm.),  and 
Peromyscus  floridanus  (N=3,  mean  weight  33.0  gm.) — were  supplied  by 
John  A.  King  at  Michigan  State  University. 

Sweet  substances  used  were  anhydrous  glucose,  sodium  saccharin,-** 
and  sodium  and  calcium  cyclamate.4 

All  &s  were  housed  individually  with  standard  (Big  Red)  laboratory 
chow  always  present  and  water  available  except  during  testing.  Using  a 
paired-comparison  procedure,  each  S  was  presented  with  pairs  consisting 
of  a  4,  8,  or  16%  glucose  solution  and  either  a  0.23%  saccharin,  0.91%  Na 
cyclamate  or  a  1.81%  Ca  cyclamate  solution.  These  particular  concentra- 
tions were  chosen  since  Stellar  (16)  reported  rats  to  prefer  maximally  a 
0.23%  Na  saccharin  solution,  and  Smith  and  Ross  (15)  found  mice  to  pre- 
fer a  1%  Na  cyclamate  solution.  Saccharin-glucose  pairs  were  presented 
between  July  3  and  24,  1967.  Glucose — 0.45%  Na  cyclamate  pairs  were 
presented  for  11  days  from  July  25  to  August  5  under  the  mistaken 
assumption  that  saccharin  might  be  only  twice  as  sweet  as  cyclamate. 
(However,  Schutz  and  Pilgrim  (14)  report  that  saccharin  is  ten  times 
sweeter  than  Ca  cyclamate  to  humans,  when  both  are  paired  with 
sucrose.)  The  Na  cyclamate  concentration  was  doubled  to  0.91%, 
approximating  that  of  Smith  and  Ross,  and  paired  with  glucose  for  15 
days  from  August  7  to  22.  For  three  days  0.91%  Ca  cyclamate  was  paired 
with  each  of  the  three  glucose  solutions.  Because  of  the  continuing 
rejection  of  the  artificial  sweetener  the  concentration  was  again  doubled 
and  the  1.81%  Ca  cyclamate-glucose  pairs  were  presented  for  15  days 
from  August  26  to  September  9,  1967.  Due  to  the  rather  preliminary 
nature  of  the  use  of  0.45%  Na  cyclamate  and  0.91%  Ca  cyclamate  solu- 
tions, the  intake  for  these  pairs  is  not  included  in  the  data  to  be  reported. 
Each  glucose-artificial  sweetener  pair  was  repeated  five  times  on  a 
randomly  cycled  schedule.  Pairs  of  solutions  were  presented  for  two 
hours  per  day.  Solution  positions  were  altered  randomly  to  inhibit  devel- 
opment of  drinking  patterns  based  on  position  rather  than  on  sweetness. 
Analysis  of  variance  was  computed  on  intake  corrected  for  body  weight 
since  there  were  wide  variations  in  weight  across  species.  The  data  are 
presented  graphically  as  percent  glucose  preference,  which  is  a  method 
that  not  only  takes  body  weight  into  account  but  also,  by  examining  their 
relative  preference  rather  than  their  absolute  intake  differences,  tends  to 
equate  preferences  for  animals  who  drink  small  or  large  amounts. 


3  The     sodium     saccharin     was     provided     by     the     Monsanto     Chemical 
Company. 

*  The  cyclamate  salts  were  provided  by  Abbott  Laboratories.

Results 

An  analysis  of  intake  uncorrected  for  body  weight  showed  that 
Peromyscus  floridanus  drank  more  and  showed  a  greater  absolute  degree 
of  preference  and  that  P.m.  bairdii  males  generally  drank  the  least  and 
showed  indifference  to  the  choices.  (The  greater  intake  by  P.  floridanus 
is  probably  linked  to  their  greater  size.)  The  fact  that  these  generaliza- 
tions are  maintained  in  the  percent-preference  data  attests  to  the  stabil- 
ity of  the  correction  factor  used.  All  further  data  presented  and  analyzed 
are  on  the  basis  of  the  intake  corrected  for  body  weight  rather  than  on 
the  basis  of  raw  intake. 

The  preference  data  are  presented  differently  in  Figure  1  from 
Figures  2  and  3  because  for  saccharin  there  are  clear  differences  in 
preference  depending  on  the  glucose  concentration.  This  glucose  depend- 
ence is  not  seen  for  the  cyclamates  since  in  all  cases  glucose  was  chosen 
to  a  very  great  extent  over  the  cyclamates  regardless  of  concentration 
(the  exception  in  all  cases  being  P.m.  bairdii  males).

Only  for  the  saccharin-glucose  choice  did  most  of  the  species  prefer 
the  artificial  sweetener  (See  Figure  1).  When  given  the  4%  glucose  vs. 
0.23%  saccharin  all  subjects  preferred  saccharin  (F=15.15;  df=l/6; 
p<.001),  with  P.  fioridanus  showing  the  greatest  preference  and  P.m. 
bairdii  males  being  indifferent.  P.m.  bairdii  females  showed  preferences 
similar  to  P.  eremicus.  P.  eremicus  showed  a  greater  corrected  intake 
than  P.  leucopus  (F=17.92;  df=l/19;  p<.005)  and  a  greater  saccharin 
preference  (F=81.0;  df=l/9;  p<.001).  No  sex  differences  were  found  for 
these  last  two  species  but  sex  differences  were  significant  for  P.m.  bairdii 
(F=16.76;  df=l/4;  p<.025). 

When  8%  glucose  was  paired  with  saccharin,  P.  fioridanus  developed 
a  marked  glucose  preference,  P.  eremicus  and  P.m.  bairdii  females 
showed  a  saccharin  preference,  and  P.  leucopus  and  P.m.  bairdii  males 
showed  no  consistent  preferences  (F=5.58;  df=6/24;  p<.001).  Again, 
no  sex  differences  were  found  for  P.  leucopus  or  P.  eremicus  although  by- 
examining  these  two  species  separately  preference  differences  were  found 
(F=5.43;  df=l/9;  p<.05).  For  P.m.  bairdii  sex  was  significant 
(F=17.76;  df=l/4;  p<.025). 

All  Ss  preferred  16%  glucose  to  saccharin,  and  it  is  obvious  from 
graphical  inspection  that  there  are  no  significant  species  differences. 

Na  Cyclamate 

The  various  glucose  concentrations  were  preferred  to  cyclamate 
except  by  P.m.  bairdii  males,  who  were  inconsistent  in  their  preferences 
as  is  seen  in  Figure  2.  Generally,  P.  fioridanus  showed  a  greater  degree 
of  preference,  and  when  these  data  are  coupled  with  the  P.m.  bairdii 
male  drinking  pattern,  there  is  produced  a  significant  species  X  sweet- 
ener interaction  (F=31.78;  df=6/24;  p<.001)  for  16%  glucose  vs.  Na 
cyclamate.  It  is  also  seen  in  Figure  2  that  the  8%  glucose  combination 
produced  a  similar  difference  in  species  preference.  P.  eremicus  and 
P.  leucopus  exhibited  no  species  or  sex-based  differences  in  preference 
for  glucose.  P.m.  bairdii  sex  differences  were  found  for  the  8% 
glucose  combination  (F— 29.24;  df— 1/4;  p<.01)  and  for  the  16%  glucose 
combination  (F=30.37;  df=l/4;  p<.01). 

In  spite  of  the  pronounced  glucose  preference,  the  mice  still  man- 
aged a  total  solid  intake  of  from  0.04  gm  Na  cyclamate  for  the  P.m. 
bairdii  to  0.07  gm  for  P.  eremicus  females,  to  0.08  to  0.10  gms  for  the 
remaining  mice. 

Ca  Cyclamate 

As  is  seen  in  Figure  3,  for  all  pairs  of  solutions,  P.  fioridanus  drank 
more  and  showed  the  greatest  glucose  preference,  P.m.  bairdii  males 
were  inconsistent  or  preferred  Ca  Cyclamate,  and  the  remaining  animals 
were  intermediate  (for  4%  glucose,  F=85.0;  df=6/24;  p<.001,  for  8% 
glucose,  F=63.0;  df=6/24;  p<.001,  and  for  16%  glucose,  F=6.37; 
df=6/24;  p<.001).  The  only  sex-based  intake  differences  in  preference 
for  P.  eremicus  and  P.  leucopus  were  found  when  the  choice  was  a  4% 
glucose   solution   or   Ca   cyclamate.    P.   eremicus   females   maintained   a 


Zoology 


461 


consistent  glucose  preference  while  the  other  Ss  showed  an  initial  glucose 
preference  changing  to  indifference  (F=3.28;  df=4/4;  p<.05).  P.m. 
bairdii  showed  consistent  sex  differences  for  all  three  pairs  of  solutions 
(for  4%,  F=14.91;  df=l/4;  p<.025,  for  8%,  F=122.1;  df=l/4; 
p<.001,  and  for  16%,  F=118.6;  df— 1/4;  p<.001). 

At  the  conclusion  of  the  exposure  to  the  three  artificial  sweeteners 
and  glucose,  the  mice  had  a  total  solid  cyclamate  consumption  of  from 
0.15  gms  for  P.m.  bairdii  to  0.21  gms  for  P.  leucopus  males. 

If  possible  toxic  effects  would  cause  an  increased  aversion  to  cycla- 
mates  with  extended  experience,  such  aversion  should  be  seen  as  the 
significant  effect  of  "days"  or  "days  by  sweetener."  Significant  "day" 
and  "day  by  sweetener"  effects  were  found  for  16%  glucose  vs.  Na 
cyclamate  and  4%  glucose  vs.  Ca  cyclamate,  and  "days"  were  significant 
for  8%  glucose  vs.  Ca  cyclamate.  However,  the  significances  were  not 
caused  by  a  consistent  decline  in  cyclamate  preference,  but  rather  by 
marked  day-to-day  variation  in  sweetener  preference  by  the  several 
species.  In  addition,  the  already  low  initial  preferences  for  cyclamates

quently, an  unequivocal  answer  is  not  provided  to  the  hypothetical  effects

Discussion 


The  species  differences  found  here  present  further  evidence  of  the 
more  general  phenomena  referred  to  in  the  introduction  (for  species 
other  than  deer  mice)  and  also  reported  for  glucose  preferences  in  deer 
mice  (21).  At  present  these  differences  cannot  be  explained  in  terms  of 
the  differing  natural  habitats.  P.  floridanus  and  P.  eremicus  live  in  xeric 
(dry)  areas  and  P.  leucopus  and  P.m.  bairdii  live  in  mesic  (moist)  areas, 
but  the  sweet  preferences  of  these  species  living  in  similar  areas  are  not 
consistently  similar.  In  fact,  there  often  seem  to  be  similar  preferences 
between  species  of  quite  different  natural  habitats.  This  phenomenon  was 
also  found  for  glucose-glucose  preferences  by  Wagner  and  Rowntree  (21). 

The  pronounced  sex  differences  in  preferences  for  glucose  vs.  sac- 
charin in  laboratory  rats  recently  noted  by  Valenstein  (18,  19)  were  not 
found  for  P.  leucopus  or  P.  eremicus,  although  P.m.  bairdii  also  showed 
consistent  sex  differences  in  preferences  for  all  three  artificial  sweeteners. 
However,  where  Valenstein  found  males  to  switch  to  glucose  and  females 
to  continue  preferring  saccharin,  here  the  male  P.m.  bairdii  remained 
indifferent  to  or  preferred  the  artificial  sweetener  while  the  females 
switched  to  a  glucose  preference.  It  is  difficult  to  evaluate  the  species 
differences  in  preference  for  Na  cyclamate  in  the  other  studies  (8,  15) 
since  the  rats  and  mice  were  given  a  choice  of  cylamate  and  water  and 
the  rats  were  partially  food  deprived.  As  Stellar  and  McCleary  (17)  and 
Wagner  and  Rowntree  (20)  have  emphasized,  the  type  of  choice  available 
determines  the  preference  (as  most  obviously  does  the  presence  of 
hunger). 

The  strong  glucose  preferences  over  the  cyclamates  are  very  inter- 
esting, especially  when  it  is  realized  that  the  1.81%  Ca  cyclamate  is 
approximately  as  sweet  as  a  16%  glucose  solution  (to  these  writers). 
This  means  that  preferences  (or  aversions)  for  cyclamates  are  probably 
not  based  on  sweetness  per  se.  There  is  also  literature  suggesting  that 
sugar  of  lead  (lead  acetate),  while  sweet,  is  avoided  by  rats  due  to  its 
toxicity.  However,  this  research  is  somewhat  suspect  in  suggesting  that 
some  sweets  are  avoided;  Mason  and  Safford  (7)  have  reported  that 
although  this  compound  may  be  sweet  it  also  has  strong  taste  components 
of  bitter  and  astringent  or  metallic  which  probably  produce  the  aversion. 
While  these  taste  components  have  not  been  reported  for  the  cyclamates, 
many  persons  do  report  anecdotally  a  different,  sort  of  "thin"  or 
"metallic"  character  in  the  taste  of  artificially  sweetened  beverages. 

It  is  not  possible  to  show  definitively  that  the  cyclamate  aversion  in 
deer  mice  is  based  on  toxicity  or  physiological  discomfort.  Nees  and 
Derse  (11)  fed  rats  for  one  year  on  diets  with  5%  and  10%  Ca 
cyclamate  added.  This  amounted  to  between  312  gms  and  780  gms  of 
total  solid  cyclamate  ingested  or  from  slightly  less  than  one  gram  to 
slightly  more  than  two  grams  per  day  for  females  and  males  respectively. 
(These  animals,  it  should  be  noted,  were  not  given  a  choice  of  an  alter- 
native unadulterated  diet.)  With  animals  averaging  over  400  gms  this  is 
equivalent  to  an  intake  of  less  than  0.1  gms  in  a  20  gm  mouse.  Addi- 
tional recent  findings  by  Tanaka  in  Japan  (personal  communication  and 


464  Indiana  Academy  of  Science 

translation  from  Nees)  suggest  that  an  acute  LD50  for  20  gm  mice  is 
.10-.20  gm  Na  cyclamate  and,  further,  that  a  more  sensitive  measure  of 
fetal  deaths,  FLD50,  is  0.0036  gm!  On  the  basis  of  these  two  studies  it  is 
quite  possible  that  the  deer  mice  could  have  taken  sufficient  cyclamate  to 
experience  toxic  effects  and  could  have  developed  an  aversion  to  these 
solutions. 

However,  it  is  not  even  necessary  to  show  that  the  animals  are 
experiencing  marked  physiological  discomfort  in  learning  an  avoidance 
since  Fregly  (3)  found  adult  rats  to  avoid  all  concentrations  of  poisonous 
LiCl,  even  those  too  dilute  to  produce  discomfort;  Rozin  (13)  also  found 
half -wild  and  domestic  rats  to  subsequently  avoid  a  Lithium-poisoned  diet 
for  a  long  time  after  having  experienced  the  ill  effects  only  once. 

This  study  points  up  the  need  for  more  research  to  separate  prefer- 
ences based  on  taste  or  other  receptors.  Toxic  sweet  substances  such  as 
xylose,  ribose,  and  dulcin  may  give  clues  to  the  basis  for  preferences  or 
aversions.  In  addition,  the  study  of  various  species  and  sex  differences  is 
needed  to  understand  further  the  basic  aspects  of  taste.

Melanoma  in  Helodernia  suspectum  Cope 

Robert  H.  Cooper,  Ball  State  University 

In  August  of  1945  two  gila  monsters  were  received  from  Arizona 
expressed  in  a  wooden  box  24"  x  16"  x  12".  The  animals  have  been 
living  in  this  same  container  continuously  since  that  time,  except  for  the 
last  few  months,  when  one  of  them  was  removed  because  of  surgery  on 
the  other.  The  animal  under  discussion  measures  497  mm  from  tip  to 
tip  and  335  mm  from  tip  of  nose  to  vent.  This  is  almost  the  exact  size 
that  it  was  23  years  ago. 

Approximately  once  a  week  the  specimen  has  received  one  raw  egg 
or  some  newly  hatched  English  sparrows  or  some  newly  born  mice  and 
rats. 

In  1963  a  projection  began  to  show  on  the  dorsal  surface  at  the 
base  of  the  tail.  By  1968  this  tumor  was  approximately  51  mm  in  width, 
35  mm  in  length  from  front  to  back,  and  20  mm  in  depth.  In  order  to 
try  to  prevent  further  migration  of  the  growth,  surgery  was  performed 
on  the  morning  of  March  9,  1968,  by  a  competent  Muncie  surgeon.  Since 
the  growth  was  of  the  type  that  had  migrated  through  the  tissue,  the 
entire  dorsal  surface  was  removed,  including  the  fascia.  The  specimen 
was  immobilized  for  the  surgery. 

The  tumor  was  taken  to  the  Ball  Memorial  Hospital  Pathology  Lab- 
oratories. Macroscopic  and  microscopic  studies  were  made  of  the  tissues 
and  cells.  Sections  were  made  and  stained  in  order  to  make  cellular  stud- 
ies, and  malignancy  was  determined.  Kodachrome  35  mm  slides  were 
made  of  the  gross  structure  and  microscopic  structure.  Kodachrome 
views  of  the  incision  were  made  from  time  to  time. 

Dr.  Montgomery  and  Dr.  Branam  point  out  that  "The  tumor  has  no 
particular  arrangement  and  occurs  simply  in  multiple  nodules  separated 
from  each  other  by  bands  of  connective  tissue.  Here  and  there,  there  are 
hyalinized  fibrous  areas  intimately  associated  with  some  tumor  cells. 
The  individual  cells  are  eliptical-oval  or  spindle  shaped.  They  have  a 
relatively  large  amount  of  brownish  pigment  in  their  cytoplasm,  and 
inspection  by  oil  power  magnification  revealed  that  many  contain  very 
large  nuclei  as  compared  to  the  nuclei  of  the  normal  pigment-bearing 
cells  in  the  epidermis  and  dermis,  and  revealed  that  these  nuclei  contain 
increased  amounts  of  chromatin  material  and  exhibit  an  irregular  bead- 
ing of  the  inner  surface  of  the  nuclear  membrane,  and  considerable  vari- 
ation in  their  configuration.  These  are  features  of  malignant  cells, 
usually.  On  the  other  hand  careful  inspection  of  many  fields  shows  no 
mitotic  figures. 

"This  particular  lesion  was  called  a  melanoma  in  the  first  analysis 
because  it  is  a  neoplastic  growth  of  nevus  cells  producing  pigment,  that 
exhibits  abnormal  cells  with  abnormal  nuclei,  and  demonstrates  invasion. 
Since  the  lesion  was  large  it  was  impossible  to  embed  all  of  the  material,

and  it  was  assumed  that  there  must  be  a  junctional  component  some- 
where along  the  line.  However,  this  has  not  proven  to  be  the  case,  and 
for  this  reason  the  lesion  might  best  be  called  a  cellular  blue  nevus,  with 
cytologic  features  suggesting  malignancy. "  The  tumor  and  microscopic 
sections  are  on  file  at  the  Ball  Memorial  Hospital  laboratory. 

Contact  had  been  made  with  Dr.  Herbert  L.  Stahnke,  Director  of  the 
Poisonous  Animals  Research  Laboratory  at  Arizona  State  University  at 
Tempe,  Arizona,  who  is  a  specialist  in  working  with  gila  monsters  and 
scorpions,  to  see  whether  there  was  any  information  he  could  give  as  to 
anesthesia  and  post-operative  treatment.  Dr.  Stahnke  had  used  barbitu- 
ates,  injecting  approximately  %  cc.  every  15  to  20  minutes.  He  had  also 
used  fluothane  in  small  amounts,  watching  the  animal  very  carefully 
and  removing  it  from  the  gas  chamber  upon  loss  of  equilibrium. 

Dr.  Sherman  Minton,  Professor  of  Bacteriology  at  Indiana  Univer- 
sity Medical  School  and  an  authority  on  reptiles,  was  also  interviewed  and 
mentioned  the  use  of  chilling  at  5°  centigrade  for  one  or  two  hours  which 
he  had  used  on  cobras,  and  then  being  able  to  work  five  or  ten  minutes 
before  the  specimen  would  become  active.  Dr.  Minton  mentioned  that 
chloroform  had  not  been  satisfactory  with  the  reptiles,  but  that  he  is 
trying  fluothane  with  success. 

Two  days  after  surgery  the  animal  was  offered  a  raw  egg  and  ate  it. 
From  that  time  on  a  raw  egg  was  broken  into  a  culture  dish  and  fed 
to  the  specimen  approximately  once  a  week.  No  healing  seemed  to  take 
place   for   some   weeks. 

During  the  last  part  of  April  it  was  suggested  by  Dr.  Minton  that 
heat  be  added  to  the  extent  of  keeping  the  temperature  pretty  close  to 
80°.  This  has  been  done  and  a  scab  has  formed  and  come  off.  On  May 
22  three  drops  of  "mycolog"  ointment  were  smeared  over  the  incision. 
This  was  at  the  recommendation  of  a  local  veterinarian  and  has  served 
as  a  control  for  fungus  and  bacterial  growth. 

Feeding  and  "mycolog"  treatment  are  continuing  and  new  tissue  is 
forming.  Shedding  has  taken  place  over  the  entire  animal.  The  surgeon 
believes  this  increased  activity  to  be  due  to  the  stimulus  from  the 
replacement  of  tissue  over  the  incision.

A  Comparative  Study  of  Some  Effects 
of  Aminoglutethimide  Phosphate 
on  Serum  Potassium  and  Sodium 

George  P.  Pollock,  Indiana  State  University 

Abstract 

A  comparative  study  of  the  effects  of  2-(p-aminophenyl)-2-ethyl 
glutethimide  phosphate  on  serum  potassium  and  sodium  concentrations  was 
conducted.  Rattus  norvegicus,  Coturnix  japonicum,  Rana  pipiens  and  Chrysemys 
picta  were  used.  A  significant  increase  in  serum  potassium  and  a  significant 
decrease  in  serum  sodium  were  observed  in  the  homeothermic  species.  No 
significant  changes  in  the  two  electrolytes  were  observed  in  the 
poikilothermic  species. 

Introduction 

The  compound  2-i-(p-aminophenyl)-2-ethyl  glutethimide  phosphate 
(AGP)  has  been  used  clinically  as  an  anticonvulsant  in  the  treatment  of 
generalized  seizure  and  petit  mal  and  temporal  lobe  epilepsy  (1).  Admin- 
istration of  the  drug  has  resulted  in  some  undesirable  side  effects. 
Changes  in  endocrine  function  similar  to  those  produced  with  amphenone 
B  were  reported  by  Hertz  et  al  (4).  Pittman  and  Brown  (5)  observed 
hypertrophy  of  thyroid,  ovarian,  and  adrenal  tissues.  Dexter  (2)  indi- 
cated a  steroidogenic  block  with  AGP  prior  to  A-5-pregnenolone.  The 
specificity  for  the  site  of  this  block  was  indicated  since  addition  of  the 
latter  compound  allowed  normal  synthesis  to  occur.  The  experiments  of 
Eversole  and  Zimmerman  (3)  suggested  that  abnormal  mineralocorticoid 
synthesis  occurred  in  rats  following  AGP  treatment,  since  they  reported 
deviations  in  urinary  and  blood  electrolyte  values  in  these  animals.  The 
present  investigation  was  conducted  to  determine  if  similar  effects  of 
AGP  are  found  in  the  serum  electrolytes  of  other  classes  of  vertebrates. 
Representative  mammals,  birds,  amphibians,  and  reptiles  were  used  in 
this  study. 

Materials  and  Methods 

Female  Rattus  norvegicus,  white  rats  of  the  Charles-River  strain, 
Coturnix  coturnix  japonicum,  Japanese  quail,  Rana  pipiens,  grass  frogs, 
and  Chrysemys  picta,  painted  pond  turtles,  were  used  in  this  experiment. 
All  animals  used  were  fasted  24  hours  prior  to  treatment  but  were 
allowed  water  ad  libitum.  The  AGP  solution  administered  was  prepared 
in  a  concentration  of  100  mg  of  AGP/ml  of  distilled  water.  Each  animal 
was  given  two  injections  of  AGP  in  a  dosage  of  100  mg/kg  body  weight 
at  12-hour  intervals.  The  injections  for  the  rats,  quail,  and  turtles 
were  given  subcutaneously  in  the  neck  region.  The  frogs  were  injected 
in  the  dorsal  lymph  sacs.  Each  control  animal  received  an  injection  of 
distilled  water  comparable  to  the  volume  of  AGP  that  it  would  have 
received  as  an  experimental  animal.  Twenty-four  hours  after  the  first 
injection,  the  animals  were  sacrificed  by  guillotining.  The  blood  was  col- 
lected, and  the  serum  was  separated  by  centrifugation.    Serum  electro-

lytes  were  measured  by  flame  photometry  using  the  "Coleman  Flame 
Photometry  Manual"  method.  This  procedure  required  serum  dilutions 
of  1:50  for  potassium  and  1:200  for  sodium  samples.  Since  small  quanti- 
ties of  serum  were  obtained  from  the  frogs  and  quail,  all  sodium  samples 
were  prepared  from  the  previously  tested  potassium  samples  to  maintain 
consistency  in  all  tests. 

The  standard    "t"  test  was  used  for  the  statistical  evaluation  of  the 


Results 

The  AGP  injections  caused  extreme  inactivity  in  the  rats  and  quail 
with  many  specimens  unresponsive  to  external  stimuli.  This  condition 
was  more  severe  and  prolonged  in  the  quail  than  in  the  rats.  Only 
initial  irritation,  shown  by  considerable  kicking,  was  evident  in  the  frogs 
and  turtles.  AGP  caused  significant  differences  in  serum  potassium  and 
sodium  concentrations  in  both  the  rats  and  quail.  These  differences  were 
expressed  as  an  increase  in  potassium  and  a  decrease  in  sodium.  No 
variations  in  these  electrolytes  were  observed  in  the  frogs  and  turtles. 
These  results  are  cited  in  Table  1.

Discussion 

Some  individuals  question  the  use  of  guillotined  animals  for  electro- 
lyte determinations  because  of  simultaneous  collection  of  body  fluids. 
The  results  of  this  experiment  are  all  relative  values  since  all  samples 
were  obtained  in  the  same  manner.  It  is  to  be  noted  that  the  control 
values  correspond  with  those  reported  by  Prosser  (6)  for  the  rats,  frogs, 
and  turtles. 


470  Indiana  Academy  of  Science 

The  results  obtained  in  the  experiments  by  Eversole  and  Zimmerman 
(3)  in  rats  were  similar  but  less  profound  than  those  found  here  in  both 
rats  and  quail.  These  differences  might  be  expected  in  the  experiments 
of  those  authors  since  they  gave  one  injection  per  24  hours  as  compared 
with  two  injections  per  24-hour  period  for  the  present  experiment.  The 
increased  response  might  then  be  attributed  to  i.  a  pharmacological 
booster  effect  of  the  AGP  titer  in  the  bloodstream,  or  2.  an  increased 
response  due  to  more  AGP  being  present  per  24-hour  period. 

The  evidence  that  AGP  produces  a  steroidogenic  block  prior  to 
A-5-pregnenolone,  prepares  one  to  assume  a  marked  reduction  or  absence 
of  mineralocorticoid  secretion  after  treatment  with  the  drug.  The 
changes  in  the  electrolytes  of  the  rats  and  quail  found  here  would  not  be 
unexpected.  Furthermore  one  might  expect  identical  changes  in  frogs  and 
turtles  since  identical  hormones  have  been  isolated  from  these  vertebrates. 
The  question  then  arises  as  to  why  there  were  no  changes  in  the  electro- 
lyte balance  of  these  animals  following  treatment  with  AGP. 

Several  possible  answers  to  this  question  exist,  but  they  are  highly 
speculative.  This  is  due  in  part  to  lack  of  a  method  for  qualitative 
determination  of  AGP  in  the  bloodstream  of  these  animals.  If  one 
assumes  that  AGP  is  absorbed  and  acts  in  cold-blooded  animals  in  the 
same  way  as  in  warm-blooded  animals,  then  one  cannot  overlook  the  idea 
of  the  existence  of  an  alternate  pathway  of  synthesis  for  corticosteroids 
unaffected  by  AGP  treatment.  There  are  tissues  of  unknown  function 
which  are  suspected  of  steroidogenic  action  in  both  amphibians  and 
reptiles  (7). 

A  second  area  that  needs  investigation  is  that  of  absorption  of  the 
compound  by  these  animals.  The  degree  of  vascularity  in  the  subcu- 
taneous neck  region  is  not  as  extensive  in  the  turtle  as  in  the  rats  and 
quail.  The  results  obtained  would  indicate  that  absorption  of  the  com- 
pound was  negligible  for  both  the  frogs  and  the  turtles.  When  the  mass 
of  the  turtle  shell  is  considered  as  part  of  the  total  mass,  and  the 
injections  were  given  on  a  body  weight  basis,  the  dose  given  to  the 
turtles  was  the  highest  received  by  any  of  the  animals.  The  frog  injec- 
tions were  given  in  the  lymph  sacs  and  should  have  reached  the  general 
circulation  more  rapidly  than  in  any  of  the  other  animals.  This  method 
of  injection  almost  insures  the  presence  of  AGP  in  the  bloodstream,  and 
since  no  response  was  illicited,  it  then  seems  logical  to  assume  the  drug 
does  not  block  steroidogenesis  in  the  frog.  Metabolic  alteration  of  AGP 
by  the  frog  and  turtle  exists  as  a  possible  cause  for  their  lack  of  response. 
If  the  compound  is  altered  to  some  intermediate  before  it  can  cause  its 
block,  then  no  change  could  occur.  To  be  able  to  support  this  hypothesis, 
some  means  of  qualitative  determination  of  AGP  must  be  developed.

Abstract 

Weight  reductions  due  to  evaporative  loss  of  water  under  varying-  con- 
ditions of  temperature  and  relative  humidity  are  presented  for  Plethodon 
jordani  jordani,  Plethodon  glutinosus,  and  Desmognathus  ochrophaeus  carolinen- 
sis,  the  data  for  the  latter  two  being  somewhat  less  conclusive.  The  experi- 
mental conditions  employed  were  those  presumed  to  approximate  conditions 
encountered   by  animals   in   nature. 

Introduction 

It  is  a  commonplace  of  even  casual  observation  that  the  various 
species  of  amphibians  do  not  all  live  under  the  same  environmental  condi- 
tions, but  that,  rather,  each  species  occurs  in  its  own  reasonably  distinc- 
tive situation.  These  situations  are,  however,  characterized  by  one  rela- 
tively constant  feature  in  that  all  amphibian  organisms  require  some 
access  to  water,  but  even  in  this  respect  there  is  a  diversity  of  habitats 
varying  from  those  that  are  definitely  aquatic  to  those  that  are  almost 
completely  terrestrial.  With  respect  to  the  capacity  to  conserve  body 
water  and  to  resist,  or  survive,  the  desiccating  influence  of  atmospheric 
air,  the  members  of  the  Class  Amphibia  thus  present  a  whole  spectrum  of 
adaptations  the  achievement  of  which  must  have  been  very  crucial  in  the 
history  of  vertebrate  evolution  toward  complete  terrestrialism. 

Among  studies  on  the  reactions  of  caudate  amphibians  to  the 
evaporating  power  of  air,  an  early  one  was  that  of  Shelf ord  (9)  which 
afforded  salamanders  the  opportunity  to  sample  a  humidity  gradient. 
Both  Plethodon  cinereus  and  Plethodon  glutinosus  spent  relatively  little 
time  in  the  dry  and  medium  parts  of  the  gradient,  and  spent  most  of  the 
time  in  the  moist  portion.  The  general  results  enabled  Shelford  to  state 
that  "P.  glutinosus  is  clearly  more  sensitive  to  dryness  than  is  P. 
cinereus"  Hall  (3)  found  that  Amby stoma  punctatum  could  withstand 
evaporational  loss  of  11%  to  47%  of  body  weight  and  still  survive.  Little- 
ford  et  al.  (4)  found  that  P.  cinereus  survived  greater  loss  of  water 
than  two  of  its  ecologically  more  aquatic  plethodontid  relatives,  Eurycea 
bislineata  bislineata  and  Desmognathus  fuscus  fuscus. 

In  a  study  of  two  plethodontids,  Aneides  lugubris  and  Ensatina 
eschscholtzii  xanthoptica  and  a  salamandrid,  Triturus  torosus,  Cohen  (1) 
found  a  differential  in  the  time  required  for  the  specimens  to  be 
desiccated  to  a  20%  loss  of  initial  body  weight,  as  follows:  Triturus 
averaging  13.9  gm,  a  mean  of  257  minutes,  Aneides  averaging  8.47  gm, 
a  mean  of  261  minutes,  and  Ensatina  averaging  5.66  gm,  a  mean  of  185 
minutes.  About  30%  larger  than  Ensatina,  the  Aneides  also  required 
about  30%  more  time  to  lose  20%  of  the  body  weight.  The  Triturus  was 
the  largest  of  the  three  by  a  considerable  margain,  yet  it  lost  20%  of  its 

472

weight  in  approximately  the  same  time  as  did  the  smaller  Aneides. 
Within  any  one  species,  Cohen  was  unable  to  demonstrate  a  correlation 
between  body  size  and  rate  of  water  loss. 

In  a  study  that  encompassed  eight  species  of  Western  plethodontids, 
Ray  (8)  stressed  the  specimens  by  desiccation  to  loss  of  a  righting  reac- 
tion, or  to  lethality.  Ray  found  a  definite  correlation  between  size  and 
rate  of  water  loss,  with  the  larger  individuals  in  each  species  showing 
the  slower  rates  of  loss,  a  relationship  which  he  claimed  to  be  an 
expected  one  on  the  basis  of  a  difference  in  surface-to-mass  ratio. 

The  experiments  reported  in  the  present  paper  were  undertaken  to 
obtain  information  under  conditions  deemed  to  be  somewhat  similar  to 
those  encountered  by  salamanders  in  nature,  but  with  the  a  priori  under- 
standing that  any  experimental  procedure  would  necessarily  be  some- 
what unnatural.  Some  of  these  conditions  were:  1.  exposure  to  a  degree 
of  evaporative  loss  that  would  be  essentially  non-stressful;  2.  an  air 
movement  rate  of  a  quite  gentle  intensity  or  magnitude;  3.  an 
experimental    run    of   moderate   length. 

Materials  and  Methods 

Routine  and  regular  maintenance  of  salamanders  of  the  type  used  in 
this  study  was  accomplished  in  a  constant-temperature  room  at  14-16°C. 
The  animals  were  housed,  in  varying  numbers,  in  either  glass  or  plastic 
containers  of  various  sizes,  marked  as  to  place  and  date  of  capture.  Adult 
Drosophila  and  small  or  medium-sized  mealworms  (Tenebrio  larvae) 
were  fed  to  the  animals  periodically.  In  addition  to  some  provision  for 
air  interchange  between  the  room  and  the  interior  of  the  container,  each 
container  was  supplied  with  sphagnum  moss  or  wadded  towel  paper, 
partly  to  supply  the  animals  with  a  means  of  concealment,  but  also  to 
provide  a  moisture-holder  that  would  incure  a  saturated  air  or  one  of 
quite  high  relative  humidity  within  the  container. 

For  the  experiments  reported  herein,  plastic  containers  6  inches  in 
diameter  were  equipped  in  the  manner  just  described,  and  each  sala- 
mander selected  was  placed  in  its  own  individual  container,  appropriately 
marked,  and  thereafter  not  fed  until  after  the  experiments  were  con- 
cluded. In  order  that  its  weight  might  be  stable,  no  salamander  was  sub- 
jected to  its  first  experimental  desiccation  run  until  after  adequate 
acclimation  to  the  lack  of  food.  For  the  experimental  runs  each  sala- 
mander was  transferred  to  and  confined  in  a  small  plastic  rectangular 
"weighing  box"  perforated  by  as  many  small  holes  as  the  box  structure 
would  permit.  The  weight  of  these  boxes  was  frequently  checked,  and  in 
such  boxes  each  specimen  was  weighed  immediately  before  and  immedi- 
ately after  each  desiccation  run.  Weighing  was  accomplished  on  a 
magnetically-damped  chainomatic  balance  located  in  the  constant- 
temperature  room.  For  transport  between  the  constant-temperature  room 
and  the  environment-control  chamber,  the  salamander  in  its  box  was 
placed  in  a  small  plastic  bag. 

The  experiments  were  conducted  in  the  exposure  chamber  of  an 
environment-control  device  known  as  a  Vapor-Temp    (Model  VP-200At, 


474  Indiana  Academy  of  Science 

Blue  M  Manufacturing  Company)  which  has  built-in  equipment  giving  it 
the  capability  of  automatically  maintaining  relative  humidities  from  34% 
to  98%  and  dry  bulb  temperatures  from  4°C  to  77 °C.  Air-flow  control 
can  vary  from  0  to  30  complete  changes  of  exposure  chamber  volume  per 
minute.  The  Vapor-Temp  is  furthermore  provided  with  built-in  features 
to  record  both  wet-bulb  and  dry-bulb  temperatures  on  a  circular  record 
sheet.  This  was  supplemented  by  the  installation  within  the  exposure 
chamber  of  standard  centigrade  thermometers,  one  of  which  was  wet- 
bulb,  the  other  dry.  By  coating  the  interior  of  the  Pyrex  glass  exposure 
chamber  with  an  antifog  solution,  complete  visibility  within  the  chamber 
was  achieved. 

In  preparation  for  an  experimental  run,  the  Vapor-Temp  was  turned 
on  and  regulated  to  the  desired  temperature-humidity  environment  within 
the  chamber.  All  runs  were  conducted  at  minimal  air  flow.  When  the 
weighed  salamander  was  introduced,  a  short  wait  ensued  until  the  desired 
environmental  conditions  were  re-established  in  the  chamber,  and  the 
run  was  then  continued  for  one  hour.  Following  this  sixty  minutes  of 
exposure,  the  animal  was  re-weighed,  and  then  returned  to  its  own 
individual  container.  Each  animal  was  then  periodically  re-placed  in  a 
"weighing-box"  and  its  weight  recorded  until  it  had  re-gained  its  original 
weight.  In  so  far  as  was  feasible,  each  animal  was  used  in  all  of  the  runs 
included  in  the  program. 

The  animals  studied  in  this  program  included  19  specimens  of 
Plethodon  jordani  jordani  and  four  specimens  of  Desmognathus 
ochrophaens  carolinensis  taken  at  Indian  Gap,  Sevier  County,  Tennessee. 
Appreciation  is  hereby  extended  to  the  Naturalist  Service  of  the  Great 
Smoky  Mountains  National  Park  for  cooperation  with  this  field  work. 
One  included  specimen  of  Plethodon  glutinosus  glutinosus  was  collected 
west  and  north  of  Dillard,  Georgia,  approximately  2.5  miles  north  of  the 
Georgia-North  Carolina  border  along  the  Betty  Creek  Road,  in  Macon 
County,  North  Carolina.  All  24  specimens  just  mentioned  were  collected 
in  a  program  aided  by  a  National  Science  Foundation  Grant  adminis- 
tered by  the  Highlands  Biological  Station,  Highlands,  North  Carolina,  at 
which  one  of  the  authors  was  a  resident  investigator.  The  two  remaining 
specimens  of  P.  glutinosus  were  both  Indiana  specimens,  one  collected  in 
the  Morgan-Monroe  State  Forest,  the  other  at  Friends  Camp  in  Putnam 
County. 

Weight  changes  experienced  by  the  animals  during  the  runs  are 
regarded  as  all  being  due  to  water  loss:  no  defecation  occurred  during 
any  of  the  runs.  In  reporting  these  changes,  the  raw  data  of  weight 
change  in  grams  have  not  been  recorded;  instead,  the  changes  of  weight 
are  expressed  as  a  proportion  of  the  original  weight.

at  once  that  the  animals  lost  weight  under  all  conditions  to  which  they 
were  experimentally  subjected,  with  two  exceptions.  At  the  bottom  of 
Table  1  the  means  recorded  show  a  general  trend  for  the  animals  to  lose 
a  greater  proportion  of  body  weight  on  exposure  to  progressively  less 
humid  air.  With  respect  to  this  trend,  a  column-by-column  inspection  of 
Table  1  supports  the  summary  which  follows. 

Lost  more  weight  at  36%/ll°C  than  at  48%/17°C  =  11  specimens: 
A14,  A7,  A8,  A10,  All,  A3,  A9,  A16,  A18,  A17,  A13; 

Lost  more  weight  at  48%/17°C  than  at  70%/15°C  =  17  specimens: 
A15,  Al,  A5,  A7,  A8,  A10,  All,  A3,  A13,  A9,  A16,  A18,  A19,  A17,  A6, 
A12,  A4; 

Lost  more  weight  at  70%;/15°C  than  at  85%/26°C  =  16  specimens: 
A14,  A15,  Al,  A8,  A10,  All,  A3,  A13,  A9,  A16,  A18,  A17,  A6,  A12, 
A4,  A2; 


476  Indiana  Academy  of  Science 

Lost  more  weight  at  85%/26°C  than  at  92.5% /29°C  =  11  specimens: 
A14,  A15,  A5,  A7,  A8,  A10,  A3,  A9,  A16,  A19,  A17. 

Thus  under  all  of  the  conditions  imposed,  from  11  to  17  of  the  19 
animals  showed  less  water  loss  per  hour  with  increasing  relative 
humidity,  or,  conversely,  greater  water  loss  per  hour  as  the  relative 
humidity  of  the  surrounding  air  decreased.  In  the  array  of  experimental 
circumstances,  perhaps  the  most  "natural"  temperatures  for  the  sala- 
manders were  the  15°  and  17°  exposures;  in  these  exposures  differing  by 
only  2°C,  the  relative  humidity  difference  was  of  22%,  and  17  out  of  the 
19  animals  showed  a  difference  in  greater  water  loss  in  the  less  humid 
environment.  Six  animals  showed  a  particularly  consistent  behavior 
under  all  conditions  in  that  they  lost  progressively  less  water  with 
increasing  relative  humidity,  as  follows:   A8,  A10,  A3,  A9,  A16,  A17. 

The  general  trend  of  the  relationships  just  reviewed  is  supportive 
on  the  thesis  that  P.  j.  jordani  exhibits  an  hourly  water  loss  rate 
inversely  proportional  to  the  ambient  relative  humidity  in  its  environment. 

In  Table  1  the  specimens  are  listed,  from  top  to  bottom,  in  order  of 
increasing  size  as  reflected  by  body  weight,  an  arrangement  that  was 
deliberately  adopted  in  view  of  a  possibility  that  water  loss  rate  might 
be  size-related.  Since  evaporative  water  loss  is  skin-related,  generally- 
accepted  principles  concerning  surface-area-to-mass  ratios  might  make 
it  logical  to  expect  that  the  smaller  salamanders  would  sustain  greater 
loss  than  the  larger  ones.  If  such  occurred,  inspection  of  the  vertical 
columns  in  Table  1  should  make  it  apparent.  Such  an  inspection  of 
Table  1,  column  by  column,  conveys  strongly  the  idea  that  the  sala- 
manders were  extremely  variable  in  their  response  to  desiccation.  Within 
this  variability,  however,  weak  trends  may  be  discerned  at  48%/17°C, 
70%/15°C,  and  85%/26°C;  under  these  conditions,  the  larger  animals 
show  a  tendency  to  lose  a  smaller  proportion  of  the  body  weight  than 
do  the  smaller  ones.

For  further  investigation  of  this  tendency,  Table  2  has  been  con- 
structed by  arbitrarily  dividing  the  19  specimens  into  five  groups,  and

a  consolidation  has  the  virtue  of  affording  slightly  clearer  evidence  of

a   weak   trend   for   the    smaller    salamanders    to    lose    more    weight    at 
48%/17°C,  70%/15°C,  and  85%/20°C  than  do  the  larger  ones. 
2.    Other  Salamanders 

Two  other  species  of  Plethodontid  salamanders  were  studied,  and 
these  were  subjected  to  an  additional  experimental  run  at  81%  relative 
humidity  and  16° C.  The  number  of  specimens  available  was  small,  and 
some  of  the  animals  failed  to  regain  original  weight  and  were  not  used 
in  some  of  the  experimental  runs  (Table  3).

Reference  to  Part  A  of  Table  3  will  show  that  the  largest  specimen 
of  D.  o.  carolinensis  was  still  smaller  in  terms  of  body  weight  than  the 
smallest  specimen  of  P.  j.  jordani  listed  in  Table  1.  The  mean  percentages 
of  weight  loss  of  D.  o.  carolinensis  shown  in  Table  3  were  consistently 
greater  than  that  of  P.  j.  jordani  exposed  to  comparable  experimental 
conditions,  a  result  logically  to  be  expected  on  the  basis  of  surface-mass 
ratio  relationships.  Also  consistent  with  such  a  relationship  was  the 
fact  that  (except  at  92.5% /29°C)  the  smallest  carolinensis  exhibited 
a  higher  hourly  loss  rate  than  did  the  three  somewhat  larger  specimens, 
all  three  of  which  were  about  the  same  size.    With  respect  to  hourly

rate  of  water  loss  in  correlation  with  environmental  condition,  the 
mean  values  recorded  in  Part  A  of  Table  3  show  a  progressive  decrease 
as  the  relative  humidity  increased.  Inspection  of  the  separate  values  for 
each  specimen  indicate  the  same  as  a  general  trend,  but  with  an 
occasional  exception. 

The  three  specimens  of  P.  g.  ghitinosus  used  included  two  specimens 
near  the  same  size  plus  one  quite  large  animal  (Table  3,  Part  B)  which 
was  in  fact  the  largest  of  the  total  of  26  animals  involved  in  these  experi- 
ments. The  two  other  ghitinosus  specimens  were  somewhat  larger  than 
the  D.  o.  carolinensis  and  near  the  mean  weight  of  the  P.  j.  jordani  used. 
This  largest  ghitinosus  exhibited  the  least  weight  loss  in  all  ghitinosus 
runs  except  those  at  70%/15°C  and  92.5% /29°C.  For  comparable  environ- 
mental exposures,  mean  weight  loss  of  glutinosus  was  less  than  of  D.  o. 
carolinensis  in  all  runs  except  that  of  92.5% /29°C,  but  greater  than  that 
of  P.  j.  jordani  in  all  runs  except  at  85%/26°C.  Although  not  consistent 
for  the  85%/26°C  and  92.5% /29°C  runs  the  mean  percentage  of  weight 
loss  in  glutinosus  generally  increased  progressively  with  reduced  relative 
humidity  (Table  3,  Part  B). 

Discussion 

One  of  the  most  striking  features  of  the  results  just  presented  is  the 
marked  amount  of  variation  observed.  One  specimen  of  P.  jordani  lost 
as  much  as  13%  of  body  weight  in  relatively  humid  air  at  92.5%  rela- 
tive humidity,  while  one  other  specimen  lost  a  rather  insignificant  0.07% 
of  body  weight;  these  represent  the  extremes  of  responses  to  conditions 
that  evoked  an  average  loss  of  3.53%  of  body  weight.  In  the  36%/ll°C 
runs  there  occurred  the  largest  "spread"  between  greatest  and  least 
weight  loss,  a  difference  of  32.41%  of  body  weight  under  conditions 
where  the  mean  weight  loss  was  12.0%;  yet  in  this  "driest"  air  of  these 
36%/ll°C  runs,  one  animal  lost  only  3.81%  of  body  weight.  The  smallest 
spread  in  response  was  seen  in  the  runs  at  85%/26°C  where  the  difference 
was  6.9%  under  conditions  where  the  average  loss  was  4.2%.  The  more 
scant  data  on  the  other  salamanders,  D.  o.  carolinensis  and  P.  glutinosus, 
exhibited  differences  more  intermediate  in  magnitude,  but  nevertheless 
show  variation. 

In  spite  of  the  very  considerable  variation  manifested,  salamanders 
of  all  three  taxa  exhibited  a  trend,  as  has  been  indicated  in  the  previous 
section,  to  lose  body  weight  in  direct  proportion  to  the  dryness  of  the 
surrounding  air.  This  response  of  the  animals  to  the  evaporative  power 
of  air  is  in  thorough  accord  with  logical  expectation. 

In  view  of  the  generally-held  view  that  small  organisms  have  a 
higher  ratio  of  surface  area  to  mass  than  do  larger  organisms,  another 
logical  expectation  was  that  the  smaller  salamanders  would  lose  more 
weight  in  percentage  of  initial  weight,  during  the  60-minute  runs  than 
would  the  larger  salamanders.  This  expectation  was  borne  out  only  to 
the  extent  that  the  data  presented  above  give  evidence  of  a  weak  trend. 
Inspection  of  the  Tables  will  show  several  deviations  from  this  expecta- 


Zoology  479 

tion,  and  one  gross  violation  of  it  was  exhibited  by  P.  jordani  No.  A2 
which  was  the  largest  of  the  jordani  series,  yet  it  sustained  the  greatest 
weight  loss  under  two  sets  of  conditions,  36%/ll°C  and  92.5% /29°C. 
These  experiments  thus  fail  to  confirm  unequivocally  a  definite  correla- 
tion between  size  and  rate  of  water  loss  found  by  Ray  (8)  yet  indicate 
more  of  a  trend  in  this  direction  than  was  found  by  Cohen  (1),  who 
found   no   correlation. 

MacMahon  (5)  studied  water  loss  rate  in  P.  jordani,  P.  glutinosus, 
and  also  Pleihodon  yonahlosse  at  20°C,  air  flow  of  2000  cc/minute,  and 
0%  relative  humidity,  and  concluded  that  the  living  salamander  was 
unable  to  exert  any  effective  physiological  control  over  loss  of  water  but 
suffered  a  rate  of  loss  determined  entirely  by  body  composition  and  body 
proportion  (surface-volume  ratio).  MacMahon  paralleled  his  studies  of 
living  salamanders  by  the  use  of  inanimate  "model  salamanders"  made 
up  of  80%  water  and  20%  agar  by  weight,  and  cast  in  molds  that  were 
exact  replicas  of  typical  individuals  of  the  three  species,  and  found  that 
these  lost  weight  at  the  same  rate  as  did  their  living  counterparts.  In 
another  report  (MacMahon,  6)  based  on  573  specimens  of  the  same  three 
species,  air  flow  rates  of  0,  1000,  2000,  and  3000  cc/minute  were  used,  and 
runs  were  made  a  0%  and  100%  relative  humidity,  all  at  20°C.  That 
water  loss  was  least  in  P.  jordani  and  greatest  in  P.  yonahlosse  was 
ascribed  by  MacMahon  to  the  fact  that  the  former  had  the  greatest,  the 
latter  the  least,  surface-volume  ratio.  Hourly  weight  checks  during  the 
experimental  runs  enabled  MacMahon  to  determine  a  critical  activity 
point  (CAP)  at  which  the  salamander  concerned  failed  to  accomplish  a 
righting  reaction.  Although  all  three  species  were  variable,  in  general 
both  P.  jordani  and  P.  yonahlosse  had  lesser  CAP  values  than  P. 
glutinosus.  In  addition  P.  glutinosus  from  montane  areas  had  smaller 
CAP  values  than  specimens  from  non-montane  localities.  These  latter 
considerations  constrained  MacMahon  to  propose  a  genetically-controlled 
CAP  in  these  salamanders. 

In  the  present  report,  in  all  runs  except  that  in  the  most  humid  air, 
the  greatest  mean  water  loss  rates  were  experienced  by  specimens  of 
D.  o.  carolinensis,  the  smallest  organism  used,  a  result  in  conformity 
with  MacMahon's  (5)  emphasis  on  the  role  of  the  surface-volume  ratio. 
It  may  also  be  pertinent,  however,  to  point  out  that  D.  o.  carolinensis 
lives  in  natural  situations  that  are  typically  somewhat  more  moist  than 
those  harboring  either  P.  jordani  or  P.  glutinosus,  so  the  faster  rate  of 
water  loss  could  be  due  to  intrinsic  morphologic  as  well  as  physiologic 
factors  that  are  genetically  determined  and  which  are  part  and  parcel  of 
the  total  adaptive  make-up  of  the  species. 

With  respect  to  P.  glutinosus,  the  mean  values  in  Table  3  indicate 
a  slower  rate  of  water  loss  than  was  characteristic  of  D.  o.  carolinensis, 
a  result  consonant  with  the  surface-volume  relationship  since  glutinosus 
is  a  larger  animal.  However,  glutinosus  also  lost  more  water  per  hour 
than  did  P.  jordani  in  all  runs  except  that  at  85%/26°C.  The  mean 
weight  in  Table  3  for  P.  glutinosus  is  skewed  upward  because  of  one 
quite  large  animal.    To   make  an  additional  comparison,  the  two  most 


480  Indiana  Academy  of  Science 

similar  glutinosus  (B2,  B3)  and  the  four  most  comparable  jordani  (A8, 
A10,  All,  A3)  were  singled  out  and  separate  sub-means  calculated  for 
each  group;  the  mean  initial  weight  for  both  groups  was  slightly  greater 
than  2.3  grams.  In  terms  of  these  sub-means,  P.  glutinosus  still  lost 
more  water  in  an  hour  than  did  P.  jordani,  and  under  all  of  the  experi- 
mental conditions.  These  P.  glutinosus  vs.  P.  jordani  comparative 
responses  to  evaporative  water  loss  are  not  in  strict  accord  with  the 
thesis  that  surface-volume  relationships  control  water  loss.  The  possi- 
bility exists  that  the  capacity  of  P.  glutinosus  to  lose  water  at  a  slightly 
faster  rate  could  be  one  facet  of  its  organization  making  possible  the 
higher  CAP  value  found  by  MacMahon  (6).  Certain  it  is  that  P. 
glutinosus  as  a  total  population  must  be  so  constituted  as  to  be  reason- 
ably well  adapted  to  quite  a  variety  of  conditions  since  it  has  a  very 
extensive  range  as  compared  to  either  P.  jordani  or  D.  o.  carolinensis,  a 
range  that  includes  much  more  non-montane  territory  than  the  high- 
rainfall  southern  Appalachian  mountainous  area  where  it  overlaps  both 
of  the  other  two  forms  (2).  MacMahon  (6)  pointed  out  that  because  of 
higher  temperature  and  lower  rainfall  animals  in  non-montane  areas 
may  have  had  to  withstand  greater  moisture-loss  stress,  and  may  have 
been  the  objects  of  selective  action  resulting  in  the  higher  CAP. 

Throughout  this  paper  attention  has  been  focused  on  the  relative 
humidity  of  the  atmosphere  surrounding  the  experimental  animals,  and 
no  analysis  or  special  study  has  been  made  of  temperature  relationships. 
In  general,  and  with  one  exception,  higher  experimental  humidities  have 
been  accompanied  by  higher  temperatures  where  evaporation  rates  could 
logically  be  expected  to  be  greater.  Furthermore,  full  recognition  is  given 
to  the  small  sample  sizes,  particularly  as  applied  to  D.  o.  carolinensis  and 
P.  glutinosus,  and  to  the  consequent  fact  that  the  results  do  not  support 
any  high  degree  of  conclusiveness.  This  investigation  was  undertaken 
in  the  spirit  of  an  exploratory  study  utilizing  a  basic  experimental  design 
that  differed  from  several  other  studies  of  a  like  nature  chiefly  in  that 
less  severe  physiological  stresses  were  imposed  on  the  experimental 
animals.  It  was  felt  desirable  that  the  actual  results,  as  set  forth  in 
the  Tables,  be  made  a  matter  of  record,  along  with  the  logical  inferences 
that  may  be  derived  from  them  in  terms  of  indicated  trends. 

The  material  presented  in  this  paper  formed  a  portion  of  a  some- 
what broader  program  used  in  another  connection  (7).  This  broader 
program  took  note  of  the  recovery  of  the  experimental  animals  following 
evaporative  water  loss.  The  time  required  for  the  recovery  of  99% 
to  100%  of  initial  weight  was  variable,  but  occurred  as  follows: 

P.  jordani — 3  hrs.  35  min.  to  38  hrs.  35  min. 

P.  glutinosus — 2  hrs.  20  min.  to  23  hrs.  11  min. 

D.  o.  carolinensis — 4  hrs.  30  min.  to  22  hrs.  56  min. 

Summary 

In  this  preliminary  study  nineteen  specimens  of  Plethodon  jordani 
were  subjected  to  relative  humidity  and  temperature  conditions  as  fol- 
lows:   36%/ll°C,  48%/17°C,  70%/15°C,  85%/26°C,  and  92.5%/29°C.  To

supplement  this,  four  specimens  of  Desmognathas  ochrophaeus  carolinen- 
sis  and  three  specimens  of  Plethodon  glutinosus  were  exposed  to  the 
same  conditions  plus  an  additional  experimental  run  at  81%/16°C.  All 
experimental  runs  were  one  hour  in  length,  and  weight  losses  were  all 
considered  to  be  due  to  evaporative  loss  of  water.  Weight  losses  were 
presented  in  tabular  form  as  percentages  of  initial  weight.  Weight  loss 
was  quite  variable,  the  extremes  extending  from  as  little  as  0.07%  to 
as  much  as  36.22%  of  initial  body  weight.  The  most  distinct  trend  evinced 
by  the  results  was  weight  loss,  or  loss  of  water,  in  direct  proportion 
to  atmospheric  dryness.  The  data  gave  weak  support  to  the  thesis 
that  water  loss  is  very  largely  controlled  by  the  ratio  of  surface-to-mass 
(or  volume).  Other  inferences  from  the  data  suggested  a  taxonmic, 
genetically  controlled,  difference  in  response  to  desiccation.  After  a 
desiccation  run,  the  animals  recovered  initial  weight  in  periods  varying 
generally  from  3  to  23  hours.

Rapid  Approximations  for  some  Chi  Square  and  Derived 

Correlational  Statistics  Used  in  the  Social  and 

Biological  Sciences.1 

Hans  W.  Wendt,  Valparaiso  University" 

Abstract 

Short-cut  expressions  are  given  which  approximate  basic  forms  of  Chi 
Square  first  and  second  order  interactions,  the  fourfold  point  coefficient  of 
correlation,  and  the  contingency  coefficient.  This  strictly  empirical  approach 
assumes  that  cell  frequencies  in  tabled  data  distributions  are  roughly  sym- 
metrical. Under  these  conditions,  differences  among  marginal  totals  of 
2  by  k  tables  are  small  and  little  error  is  introduced  by  substituting,  in 
effect,  an  average  value  for  pairs  of  unequal  diagonal  cell  entries.  The  esti- 
mates are  compared  with  conventional  solutions  for  20  examples,  with 
two  thirds  of  these  falling  within  approximately  ±  10%  of  the  value  of  the 
statistic  in  question  as  ordinarily  computed.  The  short  cuts  approach  the 
more  precise  solutions  as  the  cell  entries  involved  become  more  fully  sym- 
metrical. Criteria  are  offered  for  predicting  the  direction  of  the  error 
resulting   from   the  simplified   substitutions. 

Introduction 

Some  time  ago  a  short  cut  method  was  pointed  out  for  dealing  with 
special  cases  of  the  Chi  Square  situation  (6),  intended  to  complement 
a  number  of  standard  discussions  of  nonparametric  data  treatments  (1, 
2,  3,  5,  7).  Extensions  of  the  original  procedure  have  since  been  used  in 
experimental  work  and  in  teaching  students  to  run  rapid  over-all  checks 
on  conventional  calculations.  We  have  found  them  helpful  in  brief  treat- 
ments of  the  significance  and  correlation  topics  in  courses  for  non-spe- 
cialists who  needed  some  basic  statistical  criteria  that  could  be  used  in 
field  settings  and  would  permit  quick  decisions  without  incurring  exces- 
sive error. 

Summaries  of  the  modified  procedures  are  given  below.  Analytically 
or  empirically,  criteria  might  be  derived  by  means  of  which  some  equiva- 
lent of  confidence  intervals  would  be  available  for  these  estimates.  How- 
ever, this  complication  could  easily  defeat  their  basic  purpose.  Instead, 
we  are  presenting  a  number  of  practical  examples  (not  systematically 
selected  except  for  the  constraints  discussed  below)  where  standard 
computational  procedures  and  short  cuts  have  been  used  side  by  side,  to 
show  the  type  or  error  that  can  be  expected.  The  investigator  will  de- 
cide for  himself  in  which  situations  the  rapid  estimates  should  merely 
complement  the  more  rigorous  solutions  (as  in  preliminary  screening 
of  data  from  field  work  and  gross  checks  on  more  elaborate  work);  or 
where   circumstances    suggest   that   they   might   be   used    independently.

ble applications  of  this  methodology,  originally  based  on  behavioral  studies, 
to  biological  and  zoological  research.

The  2  by  2  table 

Experimental  and  survey  data  are  often  cast  in  the  form  of  a 
fourfold  table  of  classes  of  events  or  subjects,  with  observed  frequencies 
labelled

The  formula  customarily  used  for  determining  interaction  is 
abbreviated  from  the  definitional  expression  for  Chi  Square,  or  (without 
correction  for  continuity),

While  simpler  than  another  (basic)  expression,  computation  for  any  N 
over  approximately  50  magnitude  becomes  laborious.  Furthermore,  deci- 
mal errors  are  often  made  by  students  who  are  not  thoroughly  practised 
with  contingency  tables. 

If  possible,  the  2  by  2  table  is  set  up  such  that  all  four  marginal 
totals  are  equal.  This  design  assures  the  most  powerful  test  of  the  null 
hypothesis  and  minimizes  the  problem  of  small  expected  frequencies. 
Where  data  from  continuous  distributions  are  to  be  collapsed  into  two 
categories  on  each  variable  this  means  dichotomizing  around  the  re- 
spective medians.  Given  the  special  situation  of  successful  median  splits, 
however,  the  conventional  formula  reduces  to

Moreover,  this  expression  is  still  satisfactorily  close  to  the  long  solution 
where  only  the  general  criterion  of  "ordinal  symmetry"  is  satisfied,  that 
is,  where  observed  cell  frequencies  are  arranged  as

^  N  in  2  by  2  table3 

In  effect,  we  simply  square  the  sum  of  the  left  and  right  column  (abso- 
lute) differences  and  divide  by  total  cases.  The  procedure  can  be  equally 
well  phrased,  of  course,  in  terms  of  row  differences  as  well  as  differences 
between  diagonal  sums.  We  have  found  the  formulation  above  the  most 
practical  and  least  confusing  to  the  student,  and  it  is  consistent  with 
the  approximation  proposed  for  special  2  by  2k  tables. 


3  It  was  pointed  out  to  the  author  by  G.  Lienert  that  the  analytical 
basis  for  the  validity  of  the  above  assumption  has  been  worked  out  earlier 
by  M.  H.  Quenouille  {Rapid  statistical  calculations,  London,  Griffin,  1959), 
who   arrived   at   an   equivalent   formula   for   this   special    2    by    2    case.

If  ordinal  symmetry  in  the  table  deviates  greatly  from  complete 
symmetry  in  metric  terms,  that  is,  where  any  two  diagonal  cells  are 
greatly  different  although  the  basic  condition  stated  earlier  is  satisfied, 
X2  will  be  systematically  over-  or  under-estimated  depending  on  whether 
the  larger  or  the  smaller  diagonal  is  involved  (see  later). 

The  examples  in  Table  1,  some  taken  from  the  texts  quoted,  compare 
the  rapid  approximation  with  the  standard  method  and  show  the  conse- 
quences for  accepting  or  rejecting  the  null  hypothesis.  The  last  two 
examples  illustrate  the  type  of  error  which  results  from  gross  imbalances 
in  a  diagonal.

The  2  by  2k  table 
In  the  standard  treatment,  individual  terms  of  the  type 


(O— E);

are  summed  after  expected  (E)  frequencies  in  each  cell  are  computed 
from  the  marginal  sub-totals  of  the  observed  (O)  frequencies.  There  is 
a  special  case  where  (a)  row  totals  are  equal,  and  (b)  where  observed 
cell  frequencies  assume  only  two  different  values.  Here  the  procedure 
can  be  much  simplified.  For  example,  if  a  contingency  table

This  result  is  identical  with  the  conventional  long  solution.  If  the 
stated  equalities  are  satisfied  only  approximately,  the  identity  no  longer 
holds  in  the  general  case.  However,  it  can  often  be  written,  without

The  2  by  2  by  2  and  Higher  Order  Interactions 

One  standard  treatment,  after  M.  S.  Bartlett,  for  the  second  order 
(2  by  2  by  2)  interaction  consists  in  solving  a  cubic  equation  (4)  and 
is  rarely  given  in  textbooks.  The  reasons  may  be  the  forbidding  amount 
of  labor  required  where  no  computer  is  available  and  a  relatively  low 
efficiency  of  this  statistic.  Consequently,  other  measures  have  come  to 
be  preferred.  As  the  Ns  in  research  often  do  not  exceed  the  magnitude 
of  100  it  can  be  argued  that  there  is  mainly  one  situation  where  a  gross 
significance  estimate  for  an  interaction  may  still  be  desired.    Consider 


486 


Indiana  Academy  of  Science 


the  case  where  two  2  by  2  tables  show  suggestive  and  opposite  trends 
in  the  observed  cell  entries,  as  in  the  example,

Here  the  condition  is  satisfied  that

C>  D         C  <  D' 


where  A'+B'+C'+D'=N' 

A+B+C+D=N, 
and  N~N' 


Given  this  type  of  situation  (and  only  where  opposite  trends  are  evi- 
dent from  inspection)  a  workable  estimate  of  the  interaction,  with  df=l, 
is  possible  as

The  amount  of  time  saved   over  the  precise  long  method  tends  to  be 
substantial. 

The  examples  in  Table  3  compare  solutions  by  way  of  the  standard 
method  and  the  approximation,  respectively.  It  will  be  noted  that  the 
conditions  stated  above  are  violated  to  some  extent  in  both  cases.  How- 
ever, the  basic  opposition  of  diagonal  trends  is  still  visible.

(Speculatively  it  would  seem  that  the  approximation  given  for  the 
2  by  2  by  2  case  could  be  generalized  to  interactions  of  third  or  higher 
order.  Precise  computation  of  this  type  of  statistic  by  way  of  solving 
the  appropriate  equations  is,  to  our  knowledge,  not  usually  attempted. 
Occasionally,  however,  a  significance  estimate  might  be  sought  by  an 
investigator  if  a  high  degree  of  symmetry  is  obvious  among  the  trends 
of  all  sub-tables.  For  example,  in  the  following  hypothetical  example  an 


Zoology

interaction  may  be  suspected  among  such  variables  as  sex,  birth  order, 
affiliation  need,  and  resulting  anxiety:

Extending  the  earlier  reasoning  by  analogy,  the  resulting  2  by  2  by  2 
by  2  interaction  might  be  approximated  from  the  respective  eight  column 
differences  in  the  four  tables  as  being  of  the  order  of 


4  V 


205 


—8.2 


We  can  offer  no  empirical  check  on  this  estimate  precisely  because  no 
"standard  solution"  seems  to  be  readily  available.) 


Correcting  for  Continuity 

The  Yates  correction  is  usually  required  for  both  2  by  2  and  2  by 
2  by  2  tables  where  small  expected  frequencies  would  inflate  the  %2  esti- 
mate. It  can  be  applied  for  the  approximations  discussed  above.  For 
the  regular  2  by  2  table,  a  constant  of  2  is  subtracted  from  the  sum  of 
the  column  differences  before  squaring  the  total.  For  the  2  by  2  by 
2  table,  a  constant  of  4  should  first  be  subtracted  in  the  numerator. 


The  Fourfold  Point  Coefficient  of  Correlation 

The  definitional  formula  for  rP  suggests  that  computation  can  be 
simplified  wherever  the  cell  entries  are  symmetrical  in  nature,  that  is, 
result  from  median  splits  along  both  variables.  The  standard  formula, 


rp= 


BC— AD 


V 


(A+B)   (C+D)   (A+C)   (B+D) 


in  the  case  of  equality  among  marginal  sub-totals  reduces  to 

|  A— C|  +  |B— D| 


*p= 


N 


The   expression   disregards   the   sign   of  the   coefficient  which   is   easily 
determined  from  the  actual  cell  distribution.  If  symmetry  is  not  com- 


488 


Indiana  Academy  of  Science 


pletely  achieved  by  reason  of  tied  scores  in  the  original  data,  or  because 
a  larger  number  of  cells  cannot  be  conveniently  combined, 


rp~ 


[A — C|  +  |B— D| 

N 


Approximation  for  fourfold  point 
coefficient  of  correlation 


In  other  words,  we  add  the  absolute  values  of  the  two  column  differ- 
ences and  divide  the  sum  by  N.  This  version  of  a  correlation  coefficient 
is  readily  computed  without  as  much  as  a  slide  rule  wherever  N  is  man- 
ageable (e.g.,  an  even  number  and  under  50).  The  ease  would  seem  to 
make  it  unique  among  a  number  of  other  shortcuts  since  it  is  faster 
than  the  cosine  pi  approximation  of  the  tetrachoric,  or  the  Chown-Moran 
and  Mosteller  approximations  to  the  product-moment  measure  (cf.  5). 
The  method  may  be  particularly  helpful  for  preliminary  item  analyses 
and  gives  good  precision  with  test  data  where  near-median  splits  can  be 
achieved.  It  also  serves  as  a  general  check  where  Tp  or  possibly  r  are 
computed  by  means  of  the  standard  procedures. 

Table  4  illustrates  the  adequacy  of  the  simplified  formula  in  some 
empirical  cases.

Direction  and  Size  of  Error 

In  the  20  illustrations  presented  above  approximately  two  thirds 
fall  within  — 12  and  +8%  of  the  statistic  in  question,  and  one  fourth 
within  — 1  and  +1%.  This  evaluation  is  based  on  a  small  sample  of 
five  somewhat  heterogeneous  situations.  It  is  also  open  to  the  criticism 
that  the  cell  frequencies  were  selected  so  as  to  satisfy,  primarily,  the 
constraints  stated  at  the  outset.  In  place  of  the  gross  summary  above, 
however,  the  short  cuts  can  also  be  examined  in  terms  of  the  direction 
and  amount  of  error  to  be  expected  a  priori. 

It  can  be  shown,  and  is  demonstrated  by  inspection  of  the  sixteen 
examples  in  the  2  by  2  category,  that  the  approximation  tends  to  over- 
estimate the  exact  value  of  the  statistic  whenever  the  deviation  from  true 
symmetry  is  (proportionately)  greater  within  the  larger  of  the  two  pairs 
of  diagonal  cells.  The  exact  value  is  underestimated  whenever  dis- 
crepancies are  greater  between  the  two  smaller  cells.  At  the  same  time, 
asymmetry  in  the  smaller  pair  of  diagonals  generally  carries  less  weight 
in  the  overall  statistic  than  a  comparable  degree  of  asymmetry  involving 
the  larger  pair.  Furthermore,  it  may  be  argued  that  the  composition  of 
diagonals  in  2  by  2  tables  ("symmetrical"  in  the  sense  used  above)  is 
distributed  as  the  result  of  sampling  from  fixed  diagonal  sums.  Intuitive- 
ly, then,  larger  degrees  of  asymmetry  (in  terms  of  per  cent  discrepancy) 
would   normally   occur   within   the    lesser   cell    diagonal    because    of   the 


490  Indiana  Academy  of  Science 

small  numerical  values,  which  readily  form  extreme  proportions  as  they 
approach  zero.  This  would  not  apply  equally  to  the  cell  frequencies  ob- 
served within  the  other,  larger  diagonal.  If  this  analysis  is  correst  we 
would  expect  positively  skewed  error  distributions  in  large  scale  appli- 
cations of  the  short  cut  methods.  That  is,  (a)  underestimates  of  x2,  rP 
and  C  will  be  more  common,  and  their  amount  will  be  small — the  approxi- 
mations tend  to  be  conservative;  (b)  overestimates  will  be  less  common 
but  will  be  more  extreme  when  they  occur.

The  Food  of  Rana  catesbeiana  in  Three  Habitats  in 
Owen  County,  Indiana 

By  F.  Don  Fulk  and  John  0.  Whitaker,  Jr. 

Abstract 

A  total  of  442  bullfrogs,  Rana  catesbeiana,  was  collected,  of  which  3  67  had 
food  in  the  stomachs.  Frogs  were  collected  from  the  White  River,  strip-pit 
ponds  and  farm  ponds  by  gigging.  The  most  important  foods  in  stomachs 
of  frogs  from  the  river  were  scarabaeid  beetles,  crayfish,  lucanid  beetles, 
terrestrial  snails,  earthworms,  and  carabid  beetles.  Corresponding  foods 
of  frogs  from  the  strip-pit  ponds  were  crayfish,  Lepidoptera,  spiders,  vege- 
tation, Dytiscidae  and  Libellulidae,  and  from  farm  ponds  they  were  Rana 
tadpoles,  crayfish,  Libellulidae,  Lepidoptera,  young  Rana  sp.,  and  Aeschnidae. 

Introduction 

Among  the  papers  concerning  bullfrog  food  habits  are:  Korschgen 
and  Moyle  (7)  455  bullfrog  stomachs  examined  from  Missouri;  Korschgen 
and  Baskett  (6)  408  Missouri  stomachs;  Cohen  and  Howard  (3)  300  Cali- 
fornia stomachs  examined,  Brooks  (1)  138  Virginia  stomachs  examined, 
Perez  (9)  50  Puerto  Rico  stomachs  examined,  Surface  (10)  and  Frost 
(4)  29  and  25  Pennsylvinia  stomachs  examined,  and  Bush  (2)  18  Ken- 
tucky stomachs  examined. 

The  present  study  was  initiated  to  determine  and  compare  the  food 
habits  of  Rana  catesbeiana  in  three  different  habitats,  river,  farm  ponds 
and  strip  pit  ponds,  in  central  Indiana. 

Materials  and  Methods 

The  study  area  was  located  in  Owen  County  and  consisted  of  approxi- 
mately twenty  miles  of  the  White  River  from  Gosport  to  Freedom,  eleven 
strip  pits  and  fourteen  farm  ponds.  Bullfrogs  were  collected  in  June  and 
July  of  1966,  1967,  and  1968,  by  using  gigs  and  lights  from  a  boat  in  the 
river,  and  from  shore  in  the  ponds. 

Stomachs  were  removed  soon  after  collection  of  the  frogs  and  were 
examined  in  the  laboratory  using  a  dissecting  microscope. 

Description  of  Study  Areas 

Around  the  strip  pit  ponds  were  characteristic  rows  of  spill  piles  in 
various  serai  stages  of  succession  but  much  Rubus  was  present.  The 
ponds  were  clear  and  contained  Typha  latifolia  and  algae.  The  immedi- 
ate shore  of  most  of  the  strip  pits  was  essentially  void  of  vegetation. 

The  farm  ponds  were  in  pasture  situations  usually  with  relatively 
little  ground  cover  along  the  shore.  Typha  latifolia  in  the  shallow  end 
and  algae  were  predominant  forms  of  vegetation. 

The  White  River  meanders  slowly  through  flat  bottom  land  and 
rolling   hill    country   characteristic    of    Owen    County.     Dominant    plants

along  its  banks  are  Populus  deltoides   (cottonwood),  Betida  nigra  (river 
birch),  Salix  interior  (sandbar  willow),  and  Acer  negundo   (box  elder). 

Some  important  reptiles  and  amphibians  present  in  the  study  area 
were:  Rana  pipiens  (leopard  frog),  R.  clamitans  (green  frog),  Bufo 
woodhousei  (Fowler's  toad),  Hyla  crucifer  (spring  peeper),  and  Natrix 
sipedon    (common  water  snake). 

Discussion 

During  the  three  years  442  frogs  were  taken.  The  stomachs  of  367 
contained  food:  178  from  the  river,  111  from  the  strip  pits,  and  78  from 
farm   ponds    (Table   1.)

A  large  variety  of  animal  foods  was  represented,  undoubtedly 
because  the  diet  of  Rana  catesbeiana  is  greatly  influenced  by  availability. 
Almost  anything  that  moves  and  is  of  appropriate  size  is  probably  taken. 

Forty-four  food  items  were  recorded  from  stomachs  from  the  river 
frogs,  38  from  the  farm  ponds,  and  57  from  the  strip  ponds. 

The  six  most  important  foods  of  bullfrogs  in  the  river  listed  in  order 
of  decreasing  utilization  were  Scarabaeid  beetles,  crayfish,  lucanid 
beetles,  terrestrial  snails,  earthworms,  and  carabid  beetles.  In  the  strip- 
pit  ponds  corresponding  foods  were  crayfish,  adult  Lepidoptera,  spiders, 
vegetation,  Dytiscidae  and  Libellulidae.  In  the  farm  ponds  the  most 
important  foods  were  Rana  tadpoles,  crayfish,  Libellulidae,  adult 
Lepidoptera,  young  Rana  sp.,  and  Aeschnidae. 

Of  the  six  most  important  foods  in  each  of  the  habitats,  only  one, 
crayfish,  was  listed  in  all  three.  In  the  river  habitat,  various  beetles  were 
important,  comprising  a  total  of  35.5%  of  the  total  volume  of  food,  and 
with  three  families  of  beetles  included  among  the  top  six.  Crayfish  was 
the  top  food  in  strip-pits,  and  second  in  importance  in  the  other  two 
habitats.  It  would  appear  that  crayfish  are  often  a  major  food  of  the 
bullfrog.  Crayfish  was  the  only  food  in  the  top  six  in  the  river  which  was 
also  in  the  top  six  in  the  other  habitats.  The  similarity  between  stripped 
ponds  and  farm  ponds  was  greater,  with  three  major  shared  foods, 
crayfish,  adult  Lepidoptera,  and  Libellulidae.  The  top  food  in  the  farm 
ponds,  however,  was  tadpoles,  forming  20%  of  the  food  by  volume.   Tad-

poles  were   very  abundant  in   the   farmponds,  but  not  in  the  river   or 
stripped  ponds. 

It  would  appear  that  the  bullfrog  feeds  both  underwater  and  on  land. 
Several  of  the  important  foods,  the  tadpoles,  fish,  aquatic  snails,  and  pre- 
sumably many  of  the  crayfish,  are  probably  or  definitely  gotten  from  the 
water.  However,  it  is  possible  that  the  frogs  catch  the  aquatic  prey  while 
sitting  on  the  shore  or  in  shallow  water.  Much  of  the  food  must  be  taken 
on  land,  where  the  frogs  would  appear  to  wait  on  the  shore  for  prey  to 
appear,  probably  at  night,  as  indicated  by  the  Scarabaeids,  Lucanids,  and 
the  numbers  of  moths  in  stomachs. 

Somewhat  surprising  were  the  numbers  of  dragonflies  since  it 
would  appear  difficult  for  bullfrogs  to  catch  them.  The  frogs  might  get 
them  during  the  day  or  at  dusk  by  remaining  motionless  and  capturing 
them  as  they  light,  or  else  they  might  capture  them  from  among  the 
vegetation  at  night.  The  former  would  appear  to  be  the  case.  Bullfrogs 
were  seen  on  several  occasions  among  cattails  in  the  ponds  during  the 
day,  apparently  waiting  for  prey  items. 

Frost  (4)  stated  that  crayfish,  frogs,  and  mice  were  principal  foods 
of  larger  specimens.  Percent  volumes  of  crayfish  from  the  White  River 
were  12%,  with  21.3%  from  strip  pits  and  14.8%  in  the  farm  ponds. 
Crayfish  formed  the  highest  volume  of  food  from  the  pits  and  ponds,  but 
ranked  second  to  Scarabaeidae,  at  14.2%  in  the  river. 

Kirn  (5)  reports  a  young  bullfrog  catching  and  eating  another  frog, 
presumed  to  be  a  bullfrog.  In  California,  Cohen  and  Howard  (3)  found 
17  frogs  present  in  300  stomachs  examined.  Young  frogs,  Rana,  were 
found  to  be  a  relatively  minor  food  item  in  all  three  habitats  during  the 
present  study.  Hyla  versicolor  specimens  were  taken  from  stomachs  from 
farm  ponds  and  from  the  White  River.

Tadpoles  of  Rana  (probably  R.  catesbeiana,  R.  clamitans  and  R. 
pipiens)  were  an  important  item  in  the  diet  of  the  farm  pond  frogs. 

Minton  (8)  found  a  17-inch  coral  snake  in  a  bullfrog  stomach.  Two 
frogs  from  the  White  River  had  eaten  10-  and  11-inch  snakes,  Natrix 
sipedon. 

Minnows  were  found  in  stomachs  in  all  three  areas.  Three  species  of 
Notropis  were  taken  from  frogs  from  the  river.  Lepomis  macrochirus 
was  taken  in  both  river  and  strip-pit  areas.  A  turtle,  Graptemys  psendo- 
geographica,  was  found  in  a  stomach  from  the  river. 

Among  the  insects,  beetles  were  the  most  important  order  in 
stomachs  from  all  three  habitats. 

Vegetable  matter  from  the  three  areas  occurred  frequently,  but 
presumably  was  ingested  accidentally. 

The  average  length  of  strip-pit  frogs  was  103.5  mm;  farm  pond 
frogs  averaged  107.2  mm;  and  the  White  River  frogs  averaged  174.8  mm. 
Average  weights  were  158.8  for  the  strip-pit  frogs;  153.2  for  the  farm 
pond  frogs  and  373.7  for  the  river  frogs.  Thus  the  river  frogs  were  much 
larger,  but  part  of  the  weight  difference  could  be  attributed  to  the  heavy 
volume  of  eggs  since  78%  of  females  taken  in  June  contained  eggs,  con- 
trasting to  31.3%  in  July  and  14.3%  in  August.  All  frogs  from  the  river 
were  taken  in  June. 

It  is  likely  that  the  river  frogs  are  larger  because  of  the  relative 
lack  of  fishing  pressure  in  the  more  remote  parts  of  the  river.  The  strip- 
pits  and  farm  ponds  are  heavily  fished,  thus  the  larger  frogs  are  probably 
rapidly  removed  by  fishermen.

The  Hoary  Bat  in  Indiana 

Russell  E.  Mumford,  Purdue  University 

Abstract 

The  hoary  bat  (Lasiums  cinereus)  has  been  recorded  from  34  counties  in 
Indiana.  All  but  one  record  of  occurrence  fall  between  April  12  and  October 
5  ;  one  specimen  was  taken  January  31.  The  species  probably  breeds  throughout 
the  state.  Most  young  are  evidentliy  born  in  June.  Adult  males  appear  to  make 
up  an  extremely  small  percentage  of  the  Indiana  population. 

First  reported  from  Indiana  in  1844  by  Plummer  (11)  the  hoary  bat 
(Lasiums  cinereus)  was  long  considered  rare  in  the  state.  Lyon  (4) 
knew  of  extant  specimens  from  only  Monroe  and  St.  Joseph  Counties, 
although  other  authors  had  published  records  (either  without  specimens 
or  specimens  since  lost)  from  other  localities.  For  a  century  after 
Plummer  caught  a  hoary  bat  in  a  building  in  Wayne  County,  little  was 
learned  about  this  showy  species  in  Indiana.  Some  Purdue  University 
students  became  interested  in  bats  in  the  late  1940's  and  in  the  spring 
of  1948  shot  eight  Lasiums  cinereus  at  West  Lafayette  (12).  James  B. 
Cope  and  I  initiated  a  bat  banding  program  in  Indiana  in  1951  and  have 
been  assisted  by  Earlham  College  students  and  others  to  the  present. 
Nixon  A.  Wilson  began  banding  later.  Norman  C.  Negus  did  the  first 
bat  banding  in  Indiana,  but  worked  with  non-lasiurine  species.  John  O. 
Whitaker,  Jr.,  working  in  cooperation  with  the  State  Board  of  Health, 
has  added  numerous  records  through  the  identification  of  bats  submitted 
to  the  Board  for  rabies  tests. 

Distribution  and  Seasonal  Occurrence.  The  hoary  bat  probably 
occurs  throughout  Indiana  and  specimens  are  now  in  museums  from  25 
counties  (7,  13,  and  hitherto  unpublished  records).  Reliable  sight  records 
of  lost  or  discarded  specimens  are  at  hand  from  9  additional  counties. 

Findley  and  Jones  (1)  summarized  the  seasonal  distribution  of  the 
hoary  bat  throughout  its  contiguous  range,  but  their  data  for  Indiana  are 
incomplete.  It  seems  worthwhile,  therefore,  to  summarize  Indiana  rec- 
ords in  more  detail  herein  (Table  1).  Except  for  the  specimen  (J.  O. 
Whitaker  4003)  taken  January  31,  1967,  at  Terre  Haute,  Vigo  County 
(14),  all  records  for  which  dates  of  collection  are  known  fall  between 
April  12  and  October  5.  Most  of  the  reports  are  for  the  months  of  May 
to  August,  probably  the  period  when  hoary  bats  are  most  abundant  in 
Indiana.  The  single  January  record  suggests  that  a  few  may  winter. 
It  is  generally  felt  that  over  the  northern  part  of  the  range  of  the  hoary 
bat  (which  includes  Indiana)  the  species  migrates  southward  in  the  fall. 
Banding  to  date  has  failed  to  confirm  such  movement,  but  sightings  and 
other  circumstantial  evidence  indicate  that  migration  does  occur.  The 
hoary  bat  is  hardy  and  wide-ranging,  capable  of  long  flights.  Its 
tolerance  to  northern  winters  requires  investigation. 

Population  data  are  not  available,  thus  the  seasonal  abundance  of 
this  species  in  Indiana  is  unknown.    On  the  evening  of  May  29,  1948,  I

shot  two  of  at  least  three  hoary  bats  feeding  together  along  the  border 
of  a  pastured  woodlot  near  West  Lafayette.  Thomas  W.  Hoekstra  and 
J.  Scott  Grundy  shot  five  hoary  bats  at  dusk  on  June  27,  1962,  as  the  bats 
flew  over  a  small  pond  near  Munster  (Lake  County).  Hoekstra  told  me 
that  he  and  Grundy  stopped  shooting  at  the  numerous  bats  when  the  five 
collected  all  proved  to  be  Lasiurus  cinereus;  all  bats  seen  that  evening 
appeared  to  be  this  species.  James  B.  Cope  and  his  students  netted  and 
banded  three  hoary  bats  the  night  of  July  12,  1962,  near  Richmond 
(Wayne  County).  More  field  work  is  necessary  before  the  true  status 
of  this  bat  can  be  determined. 

Habitat.  Lasiurus  cinereus  is  thought  to  be  essentially  a  tree- 
inhabiting  bat,  roosting  by  day  among  the  foliage.  Such  known  roosting 
sites  in  Indiana  include  a  pasture,  residential  areas,  a  wooded  lake  shore, 
a  wooded  campus,  and  an  open  area  of  mixed  woodland,  brush,  and  old 
fields.  One  individual  was  taken  in  a  building;  another  was  found  cling- 
ing to  the  side  of  a  building.  There  are  a  few  records  of  skulls  and  other 
remains  of  hoary  bats  from  Indiana  caves  (2,  6),  but  neither  a  live  nor 
an  intact  animal  has  been  discovered  in  caverns  in  this  state.  We  would 
like  to  know  at  what  season  and  under  what  conditions  this  bat  enters 
caves.  Most  Indiana  specimens  have  been  shot  or  netted  about  woodlot 
borders,  along  small  streams  through  pasture  or  cropland,  or  over  ponds 
(mostly  in  non-wooded  areas).  The  eight  females  taken  at  West 
Lafayette  in  1948  were  shot  around  the  borders  of  a  pastured,  deciduous 
woodlot  surrounded  on  three  sides  by  pasture  and  on  the  fourth  by  a 
cultivated  field.  Other  species  of  bats  shot  at  this  location  include 
Eptesicus  fuscus,  Myotis  sodalis,  Pipistrellus  subflavus,  Lasionycteris 
noctivagans,  Lasiurus  borealis,  and  Nycticeius  humeralis.  Judging  from 
the  frequency  with  which  hoary  bats  are  submitted  to  the  State  Board 
of  Health  for  examination,  residential  areas  may  be  utilized  to  a 
considerable    extent.

Breeding.  The  first  breeding  record  for  Indiana  appears  to  be  that 
of  McAtee  (5),  who  reported  a  female  with  two  young  at  Bloomington 
(Monroe  County)  on  July  12,  1905.  Hahn  (3)  mentions  this  same  report, 
but  states  that  the  specimens  (now  lost)  were  taken  "in  June."  Addi- 
tional breeding  data  have  accumulated  slowly,  but  the  presence  of  hoary 
bats  in  most  parts  of  Indiana  in  summer  suggests  that  the  species  breeds 
throughout  the  state.  On  July  18,  1952,  I  shot  a  subadult  female  (U.  S. 
National  Museum  296436)  in  Jackson  County  (8).  This  bat  flew  weakly 
and  evidently  had  been  reared  locally.  A  female  (R.  E.  Mumford  2361) 
and  two  attached  young  were  captured  June  15,  1960,  at  Lafayette. 
Another  female  (Joseph  Moore  Museum  2009)  and  two  attached  young 
were  taken  in  Wayne  County  on  June  14,  1963.  Single,  non-flying  young 
(JMM  2667,  2686)  were  taken  in  Wayne  County  on  June  30  and  July  6, 
1966.  Emery  Jenkins  found  two  young  (REM  3996,  3997)  at  Brazil 
(Clay  County)  on  June  12,  1964.  An  adult  female  (JOW  2613)  captured 
at  Terre  Haute  on  May  28,  1964,  gave  birth  to  two  young  the  same  day 
(13).  It  is  possible  that  the  latter  record  represents  a  premature  birth 
occasioned  by  the  confinement  of  the  female,  for  none  of  the  eight  gravid 
females  taken  at  West  Lafayette  between  May  19  and  June  8,  1948,  had 
given  birth.  An  immature  (JOW  4836)  taken  in  Vanderburgh  County  on 
June  18,  1968,  was  probably  not  yet  able  to  fly  (forearm  length  46  mm) 
and  no  doubt  constitutes  a  local  breeding  record. 

Lasiurus  cinereus  normally  produces  two  young  per  litter;  nine 
gravid  females  and  three  females  with  attached  young  from  Indiana  each 
had  this  number.  In  contrast,  the  smaller  red  bat  (Lasiurus  borealis) 
usually  produces  three,  and  sometimes  four,  young  per  litter.  Parturition 
in  hoary  bats  in  Indiana  probably  occurs  mostly  in  late  May  and  the  first 
half  of  June.  The  largest  embryos  examined,  both  from  a  female  taken 
June  1  in  Tippecanoe  County,  each  had  a  forearm  length  of  16.5  mm. 
Two  young,  born  to  a  confined  female  in  Vigo  County  on  May  28,  had 
forearm  lengths  of  15  and  17  mm.  At  birth,  young  probably  have  fore- 
arms measuring  from  16  to  20  mm  (9,  10).  Single  flying  young  taken 
July  18  (Jackson  County)  and  July  19  (Howard  County)  each  had 
forearm   lengths   of   53   mm. 

From  available  data,  adult  male  hoary  bats  are  quite  rare  in  Indiana, 
especially  from  April  through  June.  One  (JOW  4946)  was  captured  in 
Jennings  County  on  May  31,  1968.  For  the  April  to  June  period  there 
are  records  of  40  adult  females  (for  a  few  sight  observations  the  sex  is 
not  known).  Likewise,  most  July  and  August  records  for  adults  are  of 
females.  Some  of  the  males  taken  in  July  and  August  are  of  questionable 
age,  but  most  are  clearly  young  of  the  year.

INSTRUCTIONS  FOR  CONTRIBUTORS 

Eligibility 

Indiana  Academy  of  Science  members  in  good  standing-  are  eligible  to 
submit  papers  for  publication  in  the  Proceedings.  When  a  paper  is  signed 
by  more  than  one  author,  at  least  one  must  be  a  member  of  the  Academy. 
Preferably,  eligibility  should  be  established  before  submitting  the  paper,  as 
such  papers  are  given  priority.  In  any  case,  all  authors  must  be  certified 
by  the  treasurer  for  payment  of  dues  and  old  reprint  bills  at  the  time  of 
the  deadline  (see  below).  Invited  papers  may  be  considered  for  publication 
regardless  of  the  membership  status  of  the  author. 

All  papers  submitted  for  publication  in  full  will  be  reviewed  by  qualified 
reviewers,  selected  by  the  Publication  Committee.  Papers  read  by  title  only 
at  the  Fall  Meeting  may  also  be  considered  for  publication.  Among  papers 
of  primarily  regional  interest,  e.g.,  in  certain  aspects  of  botany,  zoology, 
geology,  geography,  and  anthropology,  those  dealing  with  Indiana  material 
will  be  accorded  preference.  The  selection  of  papers  for  the  Proceedings  is 
the    responsibility    of    the    Publication   Committee. 

Abstracts 

Two  copies  of  an  abstract  should  be  submitted  to  the  Divisional  Chair- 
man at  the  time  the  title  of  a  paper  is  submitted  for  the  Fall  program.  All 
abstracts  will  be  published  in  the  Proceedings,  either  separately  or  with 
papers  that  are  published  in  full.  The  original  copy  of  the  abstract  should 
be  marked  "for  the  editor."  The  carbon  copy  of  the  abstract  should  be 
marked  "for  the  divisional  chairman"  and  may  include  information  about 
time,  projection  facilities  needed,  etc.  The  abstract  should  be  prepared 
according  to  the  form  used  in  the  Proceedings  (see  any  current  copy  of  the 
Proceedings).  The  abstract  should  be  complete  and  clear  in  itself  not  over 
5%  of  the  length  of  the  paper.  Normally  abstracts  should  not  exceed  200 
words  in  length.  Abstracts  are  not  reprinted  (except  for  those  which  are 
included  at  the  head  of  a  paper  published  in  full). 

Deadline  at  the  Editorial  Office 

When  sent  via  the  Divisional  Chairman  as  prescribed,  or  directly,  all 
material  to  be  considered  for  publication  in  the  Proceedings  must  reach  the 
editor   within   20   days    following   the   Fall    Meeting. 

Preparation  of  Manuscripts 

A.  Refer  to  current  copy  of  the  Proeedings  for  the  accepted  style  of 
abstracts  and  papers,  and  follow  this,  especially  in  literature  citations, 
headings   and   footnotes. 

B.  Type  on  11  x  S^-inch  bond  paper  with  a  new  ribbon,  leaving  some 
margin.  Double  space  everything-,  including  title,  author's  name  and 
institution,  footnotes,  quotations,  legends  and  literature  list.  Manu- 
scripts should  be  submitted  in  duplicate.  The  original  "will  become  the 
printer's  copy;  if  it  must  be  retyped,  it  will  be  sent  back  to  the  author 
for  this. 

C.  Footnotes  should  be  kept  to  an  absolute  minimum.  Necesasry  footsteps 
sliould  be  numbered  consecutively  throughout;  asterisks  are  not  used. 
Footnotes  should  be  referred  to  in  the  text  as  superscripts,  without 
parentheses. 

I).  Literature  citations  should  not  occur  in  footnotes,  but  should  be  in 
an  alphabetized  list  at  tbe  end  of  the  paper,  headed  Literature  Cited. 
This  list  should  contain  only  literature  citations,  no  footnotes,  quota- 
tions, parenthetical  remarks,  etc.  The  highly  abbreviated  form  used 
by  the  chemists  has  not  been  adopted  for  the  Proceedings.  Follow 
this  model:

References  cited  should  be  numbered  consecutively  (in  the  alphabetized 
list)  and  should  be  referred  to  in  the  text  by  number  in  parentheses  on 
the  line  of  type  and  before  the  period  if  at  the  end  of  a  sentence. 

B.  Only  initial  letters  or  the  words  for  special  emphasis  in  the  text  should 
be  capitalized.    Do  not  capitalize  words  in  title  or  subheadings. 

P.  Do  not  underline  anything  except  scientific  names,  anywhere,  and 
titles  of  books  when  they  appear  in  the  text  only,  not  in  literature  list. 

G.  All  literature  listed  and  all  tables  and  illustrations  used  should  be 
referred   to   in   the   text. 

H.  Tables,  which  are  costly  to  print,  should  be  reduced  to  a  minimum. 
Avoid  small  tables  scattered  through  the  text.  Each  table  should  be 
typed  on  a  separate  letter-size  sheet  and  placed  at  the  end  of  the  paper. 
Outsize  tables  cannot   be  accepted. 

I.  Photographs  should  be  printed  on  glossy  paper  and  have  good  contrast. 
It  is  best  to  mount  them  trimmed  to  fit  tightly  together  at  the  edges 
in  groups,  on  stiff  cardboard  with  rubber  cement.  Proportion  the  group 
for  a  full  page  of  the  Proceedings,  or  use  the  full  width  of  the  paper 
(4%")  and  any  part  of  the  page's  height.  Do  not  mix  line  drawings 
and  photographs  in  the  same  group.  Legends  should  be  on  a  separate 
letter-size  sheet,   numbered   to   correspond  and  placed  at  end   of   paper. 

J.  The  originals  for  line  drawings  need  be  no  more  than  twice  the  size 
desired  for  the  printed  figure.  They  should  be  proportioned  and  arranged 
to  fit  the  page  size  of  the  Proceedings.  The  lettering  should  be  carefully 
done  and  of  suitable  size  to  allow  for  necessary  reduction.  Do  not  sub- 
mit printed  maps  when  the  necessary  reduction  will  efface  the  narrower 
lines  or  render  some  of  the  lettering  hardly  legible;  such  maps  should 
be  redrawn  and  lettered  in  adequate  siz  eletters,  omitting  unnecessary 
details.  The  use  of  a  carbon  ink  on  a  heavy  white  paper  or  other 
suitable  surface  reproduces  well.  The  typewritten  label  does  not 
reproduce    well. 

K.  Major  professors  are  urged  to  review  all  papers  by  their  graduate 
students,  for  both  form  and  content,  before  they  are  sent  in  for  publica- 
tion. Of  those  based  on  university  theses,  manuscripts  carrying  the 
approval  by  the  professor  will  be  given  preference  over  those  without 
such  approval.  New  authors,  especially,  are  reminded  that  a  scientific 
paper  should  summarize  the  work,  not  recapitulate  it.  It  must  be  much 
more  concise  than  a  university  thesis,  avoiding  all  extraneous  material, 
especially  long  tables  and  lists  of  little  interest  except   to   the   author. 

B.  Reprints  of  papers  are  paid  for  by  authors,  at  cost.  Directions  for 
ordering  reprints  accompany  the  galley  proof  and  the  orders  are  placed 
at  the  time  the  author  returns  the  corrected  galley  proof  to  the  editor. 
The  order  form  supplied  by  the  editor  must  be  completed  and  returned. 
If  you  have  any  special  institutional  form  regarding  payment  for  the 
reprints,  these  should  be  sent  directly  to  the  treasurer  of  the  Indiana 
Academy  of  Science  at  the  time  the  reprints  are  paid  for.  Abstracts  are 
not  reprinted. 

M.     The    editor   needs,    at    the    time    he    mails    out    galley,    current    addresses 

for  all  authors  and  coauthors  of  all  abstracts  and  papers.  Many 
former  graduate  students  lose  the  opportunity  to  order  reprints  when 
there  are  faulty  forwarding  addresses.  It  is  suggested  taht  the  stu- 
dent's pemanent  home  address  be  written  on  the  reverse  side  of  the 
abstract  copy  marked  "for  the  editor."
