Enders Frank Wade R. C. Friesner E. B. Williamson W. A. McBeth John S. Wright The minutes of the last meeting of the Executive Connuittee were read and approved. Committee reports were considered as follows : BIOLOGICAL SURVEY. The Secretary reported informally for the Chairman, H. S. Jackson, that no specific steps have been made to gain the cooperation of the State Con- servation Commission in a systematic survey. In the absence of formal report from Stanley Coulter of the Special Com- mittee on Affiliation with the A. A. A. S. the meeting was considered in- formally. At present 87 members of the Academy of Science are members of the A. A. A. S. and 57 of the A. A. A. S. members residing in Indiana are not members of the Academy. Affiliation would yield an immediate net gain of approximately 57 members.

Just at that time Professors Cicorge Lefevre and W. C. Curtis of the University of Missouri were carry- ing on their brilliant investigations on the artificial inoculation of fishes with the glochidia of Unioiiidie. They desired a large number of fine muck- ets. and Professor Cox was able to supply them with abundant and excel- lent specimens from the Wabash. In a letter to Professor Cox, Dr. Lefevre wrote : "I want to thank you for your kind assistance in securing for our recent experiments at La Crosse such a fine lot of muckets and yel- low backs. They were received in excellent condition and furnished us with an abundant supply of glochidia for the infection of the fish. Twenty-two of the muckets contained ripe glochidia and fifteen of the yellowbacks, yielding altogether a sufficient quantity for the infection of nearly the entire lot of fish which we had on hand, namely, about 25,000. "There was no indication that the muckets were not at the height of the breeding season, as the pouches were gorged with glochidia in every specimen containing them, but the yellowbacks appeared to be on the decline, as we found quite a number of completely spent fe- males. The experiments were highly successful in every way. and we are gi-eatly indebted to all who contributed their assistance to the work." Soon after his election as head of the department of Biology in the Indi- ana State Normal School, the State Legislature i>rovided for the teaching of agriculture in the public schools. Provision for instruction in that subject in the Normal was at once made, and Professor Cox was placed in charge. This was in addition to his other numerous duties. The rooms in the basement, then occupied by the department of Biology, were soon outgrown and. largely through the efforts of Professor Cox, a new Science Hall, adequate in its ai)pointnients and architecturally beautiful, was soon 48 Proceedings of Indiana Academy of Science. provided for his department. One of the unique features of this building, the general plans for which were made by Mr. Cox, is a roof garden for which he had longed and of which he had dreamed for many years. In that roof garden he grew a large part of the plant material used in his Iwtanical work. Cox was also a good photographer, so he made provision in the new building for a well-equipped dark-room where he developed thousands of negatives and made vast numbers of stereopticon slides of which he made constant use in his teaching. In his home he had a well-equipped printing press which he had installed for the use of his son Warren, but it is more than likely he made greater use of it than did the son. On this press he printed the outlines of his lec- tures, laboratory directions, syllabi of subjects, and many other aids to teaching and for distribution among his students. Mr. Cox possessed considerable musical ability. He sang tenor very well, and, while at Mankato, organized and directed an orchestra in the Normal School. When agriculture was added to his subjects in the Normal at Terre Haute, he found the experience and training he had gained on his father's farm of great benefit to him and his students. He soon bought a small farm south of town which he largely used for experimental and instruc- tional purposes with his classes. As already intimated in this sketch. Mr. Cox was a man of broad interests and varied attainments ; he was an all-round man in the best sense of the word. As a man of affairs, he was active in civic, scientitic, and educational circles. He took a keen and active interest in matters of community and public concern. As a naturalist, he was most interested in birds and botany, bat his natural history studies were not confined to those lines. He early showed an interest in mollusks as evidenced by his paper on the mollusks of Randolph County. Mr. Cox was equally and unusually efficient, whether in the field as a collector and observer, or in the laboratory and class-room as student. teacher or investigator. During his student days and as my laboratoiy assistant in the Indiana State Normal School, he was (with the exception of Dr. Scovell) my most frequent companion on trips a-field. Together we explored practically all the woods, fields, ponds, and streams within a radius of ten to fifteen miles of Terre Haute. Among favorite places to which we frequently went were the Five-mile pond north of town. Coal Creek, Honey Creek, and the Goose Pond some nine miles south of the city. These were all places of unusual interest to the zoologist and to the botanist. The Goose Pond was most interesting, t\)r there we found several species of birds not often seen elsewhere in the county — among them the least bittern, great bittern, coot, pied-billed grebe. Carolina rail, and Vir- ginia rail. All of these species nested in that pond. Most interesting of all, we found the white water lily there in abundance. Mr. Cox suggested that we gather a considerable number of these beautiful, fragrant flowers and take a bouquet of them to certain students who were ill. The flowers were so abundant that we gathered not only enough to take a fine bouquet to each student whom we knew to be ill. Init we took one to every young lady student in our classes, and to each lady member of the faculty !

Marconi, his voice is heard in the uttermost part of the earth. These discoveries, and especially the frformauce of the task assigned to me Jis president of the Academy, to call your attention to an old theme: namely, the imixtrtance of the gen- eral laws of biology in social progress. That the evolution of human society follows the same laws that control evolution in other fields, is a fact often repeated since Herbert Spencer and Huxley insisted on its importance. In both cases evolution is essentially a process of differentiation and integration of parts or units originally alike and equal. The nature of these changes is shown in the embryonic develoi»- ment of every higher plant or animal, the multiplii-ation of cells being fol- lowed, on the one hand, by divi.sion of labor, formation of tissues, organs and organ systems, on the other hand, by coordination and integration of associated parts to form a complete whole. Societies are formed in the same way. Beginning with a group of individuals which do all kinds of work, by division of labor and cooperation they form complex organizations which are able to accomplish vastly more than separate individuals could do. Here, also, as in animal and plant bodies, the greater the division of labor, the more dependent become the pjirts on the whole, the more de- pendent the whole upon the parts. This tendency to differentiation in organisms is limited by other laws which produce more or less uniformity and stability. In embryonic life this conservatism leads to a repetition of ancestral history, in which the em- bryo follows a certain definite path and gives rise to an individual of a (51) 52 Proceedings of Indiatm Academy of ^Science. defiiiito pattern. Even embryo man is not ashamed of his ancestors, although some adult men are. If this condition dominates both adult and eml»ryonic life, the species may continue indefinitely without change, like the brachi- opod Lingula, the same today as in Cambrian time. Differentiation on the other hand, creates new species and thus forms the basis of progressive evolution. Continuous repetition of the process through long periods of time has given rise to all the higher animals and plants. In the great majority of organisms, however, progress has been slow, and in many cases, has ceased altogether. Of the vast number of species that now live, or have lived, on the earth, only a few liave found the path leading to high ranlv. These diftei-ences in the caiKicify of organisms for progressive evolution may be explained in n way by sayin-i that certain types are moi'e plastic than other-. Some are easily moulded into new shapes, while others clumge slowly (u- not at all. When such a species reaches the limit of dirt'erentia- tion permitted by its organizaticn, it may continue to exist cu the same plane, but it can not advance. According to Herrick, the evolution of the whole group of arthopods has been definitely limited by the lack of plasticity of the ladder type of nervous system, which apparently reached its highest development in cretaceous insects about two million years ago. At the same time also were established those rigid instincts which have continued with- out change down to the present. The more plastic tubular nervous system of the vertebrates, on the other hand, has shown itself capable of enor- mous development, and has provided the nervous equipment of those ani- mals in which inherited instincts are largely controlled by intelligence. With a nervous system constructed on the tubular plan, the mammals have advanced farther than other animals, but among these only the primates reached the highest grade of development. From this group finally came man. With the advent of man the old laws of evolution continue to operate, but they are more or less under the control of intelligence, which becomes a factor of increasing importance. As men were drawn together for pro- tection or otherwise, societies were formed and division of labor occurred, but no physical differences api^eared. such as are found in other animal societies, and thus each individual man retained the capacity to do all kinds of work. In such societies were laid the foundations for those col- lective activities, such as language, literature, science and government, whicli go to make up civilization. Henceforth each generation receives not only the heritage of the germ cells but also a heritage of knowledge accumu- lated by previous generations. By virtue of man's superior mental capacity, eacli generation appropriates the inherited wisdom, adds its own contribu- tion to the general store and transmits the whole to its successor. In this manner the social heritage is enlarged. Continuous operation of the general laws of evolution in human history is indicated by the appearance of different types and races of men, the inhabitants of different regions showing different characteristics, as in the case of lower organisms. As population and division of labor increased, more or less permanent conditions developed, but many of the early societies have doubtless disappeared without leaving a trace of their existence, while others are known oidy by implements or otluM- remains. Among the surviving peoples all grades of culture are re)iie ented. many luiving ceased 1 r\i<\\\ linn liic iiiiiiKili linily li;is sliiiwii >sl.nni.

Under this ideal, differentiation is linuted to differences in mental capacity, we.ilth nr occupation, and each individual is free to make the most of himself. The ensuing struggle results in the d(>velnpment of the fittest and thus pmnurtes the welfare of society. Recently the adequacy of this ideal has been called in question by the advocates and supporters of a new experiment in class government. In Russia, the ancient stronghold of democracy, revolution has usurped the Itlace of evolution, the government of the Czar has been overthrown, and in its place has been set up an autocracy of the proletariat, "the worst autocracy the world has even known". This system destroys the incentive to individual effort by denying the right to hold private i»roiterty or to engage in private enterprise. liy confiscating the property of the cipitni- istic classes, this system has thus far maintained itself and is spreading i's poison throughout the world. In the immediate future it is a factor to he reckoned with, both in Europe and Asia. Spasmodic outbreaks may also occur elsewhere, nevertheless the influence of Bolshevism seems to be waning as its funds approach the point of exhaustion, and the final result of the experiment, apparently, will be to strengthen the cause of govern- ment by all the people. Another problem, the .soluticm of which lies still in the future, is the liroblem of international relations. The need of adju.stment in tliis field has been recognized only in recent times. In international affairs, the rise of civilization has been marked by natural selection, — the "ape and tiger method" which figured so largely in the evolution of lower organisms. In the past, and even in recent time, attempts have been made to justify this method on various grounds. But conditions have changed. Modern na- tions are no longer isolated, as were the ancients.

In the case of man, the increase of population must ho limited finally hy the su])ply of food and other necessities. In China and India, at the pres- ent time, population varies directly with the fof)d supply. A similar condi- tion, which existed in Japan for more than 150 years, was brought to an end iiy contact with Western civilization and the adoption of AVestorn methods and inventions. As a result, population in Japan increased 00 per cent, from 1871 to 1915, and the increase still continues. A somewhat similar change occurred in Europe after the Industrial Revolution. About 300 .\cars ago the population of Eux'Oiie had become stationary because of a high death-rate due to war. famine and i)lagues. When the discoveries of science made possible the control of devastating diseases and provided for a more constant food supply, population increased rapidly. At the present time, because of a declining birth-rate, population is again apjiroaching e(|uilibrium. — a condition already reached in France. In England, between 1S71 and 1911, the rate of increase declined from 1..38 per cent, per annum to 1 per cent, per annum, and the same tendency is evident in the rintod States and elsewhere. According to East, the high cost of living, due to decrease of the food supply, is the chief cause of this decline, but it is not the only cause. Under conditions now existing in international affairs, when ndlitnry strength is one of the chief concerns of nations, the present tendency of the birth rate is naturally considered undesirable. If the population of France h:id increased as rapidly as that of Germany after 1871. the Kaiser would probably have hesitated to begin the world war in 1914. But the laws which control population are not easily changed to satisfy national ambi- tions or fears. It is well, therefore, to recognize the fact, that unless science comes to the rescue with improved methods of food production, the birth-rate of civilized nations must continue to decline until population be- comes stationary. The deplorable feature of the situation, from a biological standpoint, is the fact that the decline of the birtlv-rate is selective: it is greatest in those classes of society, which by reason of heredity and education, should be ex- l>ectO(l to contribute offspring of greatest value. Such conditions have not Ikhmi confined to modern times. In the two centuries from 500 F>. ('. to .300 I'.. ('.. Greece produced a group of men whose achievements, judged hy modern standards, indicate native ability of a high order. But the bril- liant Athenian race declined, and many smaller groups. — families of states- men, artists and scholars of later centuries, have completely disappeared. Few families of this class, according to Broman. survive a period of 250 years. In these modern times, society takes the talented child and educates him largely at public expense, in order that he may contribute something of immediate value to the state, but the conservation of this talent for the UM> of future generations is a matter in which society has taken little interest. Man is wasteful of coal and of other resources of the earth, but 56 Proceedhifjs of T)iiri(ni(t Acddciiij/ of l^cience. for these he has at least the hope that he may find substitutes. The. most deplorable waste is the waste of the hereditary sources from which genius springs. Professor Cattell tells us that a Harvard graduate has, on the average, three-fourths of a son. a Vassar graduate, one-half of a daughter. College graduates are regularly informed by the comraencemeut speaker that they are the salt of the earth, the leaven of the whole lump of society, but in a biological sense the leaven is weak and the salt has lost much of its saltness. The call for highly eilnc-itt'd men in the universities, colleges and the professions is greater today than ever liefore and it is certain to increase. If present tendencies continue, the future will see a great drain on the biological resources of the civilized nations. In order to improve his stock, the breeder of domestic animals selects only perfect specimens ; lie knows that elimination of the superior animals will mean race deterioration. Has human mental capacity declined be- cause the talented ones of past ages failed to i)erpetuate their kind? There are those who believe that such a decline has occurred since the days of Aristotle. Perhaps it is safe to say there has been no great improvement. But this much is certain. Heredity is a factor in mental evolution, and if hiunan talent had maintained itself in the past without loss, the average mental capacity of modern civilized man would lie higlier than it actually is. Whether a decline of this average mental capacity has occurred, or will hereafter occur, must depend on the relation between losses and gains. To balance the loss of talent in the educated classes, there is the possibility of increase from mutations, or talent may increase in a latent condition. We know that heritable variations have occurred in the past; the exist- ence of different races of men is sufficient evidence of this. But if this evidence seems to justify the belief that progressive mutation of the mental faculties occurs today, we are still ignorant in regard to the fre- quency of their occurrence. We are not certain that they replace any considerable part of the losses of talent in civilized countries. There is, however, more or less latent talent among men, in families whose members are imdeveloped because of lack of education. In the United States and other progressive nations the amount of such talent may also be aug- mented by immigration. From all of these sources, it is possible the in- crease may be sufficient to fill the places made vacant by the extermination of educated families. But substitution is not restoration. The losses on the firing line can not be made good by calling up the reserves; the total strength of the army is nevertheless reduced. We must conclude that man is advancing socially at the expense of his biological heritage. Whether this heritage is increasing or decreasing is uncertain, but under the most favorable conditions, society is falling behind the high development of which it is capable. At present the only hope for improvement lies in a cam- paign of education. Society should see to it that the rewards of service are sufficient to enable the educated man to live a normal life as head of a fam- ily. The educated man should appreciate his obligations to society. The problem is to discover a way to utilize available talent and at the same time to conserve it for future generations. But if civilization has been unfavorable for the reproduction of the edu- cated classes, it has been especially favorable for the reproduction of the uneducated. In fact, it has become a veritable paradise for the unfit.

The entire situation, as I have described it, may be summarized as fol- lows: In the development of society certain laws of progressive evolution h.ive been violated. Man has produced an artificial environment in which the defective classes are increasing while the educated classes are not per- petuating themselves. He has permitted the formation of .social .groups but has not insisted on the proper coordination of these organs of the social ^ody.

The scientist is interested in the solution of the.se problems because he is a citizen, and since the problems are largely scientific, he should assist in their solution. I will not go as far as Groves, who says that since the scientist has made our era. he is also icsixmsible for its proi)lems. The duty of the .scientist is investigation. Our social problems have ari.sen because of the weakness of human nature. The supreme test is this: .Can human intelligence devi.se plans for o\-ercoming the defects of our social system, and having found such plans will it be able to make them effective? Looking backward at the progress already made, there is reason for encouragement. Present conditions have been reached through a long Itrocess of development. There is every reason to believe that the .scientific era of society has only begun.

F latest pronouncements that have come to my knowledge ;ire by Sir (Miver Lodge an within which it is thus demonstrated and acepted are, it seems to me. far from beinu settled, and it is difficult to determine where fact ends and imagination begins. Thus. we are told by the evolutionist of a germ, — an atom of protoplasm that in some mysterious way and at some time in the dim and distant past ap- peared in pi'imeval slime, and from which all liviim things have been evolved, and that this germ was the bearer of life to or.r globe, of course evolution, as thus conceived, assumes the pre-existenee, somewhere, of this initial germ, this life bearer. If we become incpusitive concerning the life with which this initial germ was charged, they sidestep, and we are blandly informed that evolution does not deal with origins or with begin- nings,— it only deals with the way things have gone on since the germ ai>- peared. I find that where knowledge ends, science does not hesitate to .guess, surmise and imagine. So various guesses aiv ventured concerning the germ, with its inseparable companion or property, life: among others, that the original germ may have been wafted to us from space on the wings of an atom of cosmic dust. T.ut as our earth is itself, relatively to the lunverse. only a speck of dust in illinutable space, this guess only transfers the genesis of the germ to some other speck of cosmic dust, and tells us nothing of the life it carried. Another guess is that through some myster- ious process of nature's chemistry. i)rotoplasm happened to form, with life as one of its insei)arable jn-operties. and chemists have been industri- oiisly trying to learn just bow this ha])]ien(Ml and to make artificial proto- plasm, and with it. of coiu-se. lite.

And now, with much timidity, as against some of these guesses and im- aginings of science, I venture my suggestions, which are. of course, only my guesses and imaginings. To me it seems a certainty that back of all the complexity of that which we call nature, is a suprtMne intelligence, which is made manifest l)y the operation of law, — law which so far as we can grasp the idea of infinity is infinite in its oi^eration, — law which in the reach of its grasp, as well as in the certitude of its control, passes any boundary which we have lieen able to reach with any instrument yet devised, — S!oinr Gncs.scs hi/ (in J (/iioraitius. 67 whctlicr of Illinois iiiiinitc bcynnd llic jxiwcr df llii- niicroscopc. or of tliiiijrs vast Ik'.VoIhI I lie Ic.-K'll of I lie Iclcscopr.

To me there is only one elementary force, all the various so-called forces being due to the manner in which that one ele- mentary force manifests itself under varying condit+ons. My imagination carries me further, and to me life seems to be nothing more than one of those forces.- nature's organizing and con tructive force, nature's master builder: that germs are its trestlehcards on which it finds the iierfect plans for the structures it is to build, whether that structure is intended to be a tree, an earthworm, or a man: that protoi)lasm .-ind germs have not Just happene(l. but that they are a part of the plan of that supreme intelli-jeiice : that each germ embodies an idea of that suprenu' intelligence, and that in each of these germs life, the builder, finds every detail of the future tre(>. plant, flower, or aninml. True. I have been told that in aninnil life, uj) to a certain stiige in the development of the embryo, it is not ixtssilde for us to distinguish between the human embryo and that of other animals. While this may all be true, is it not also true that life never encounters any such ditticulty'.' < >n the contrary, when life begins its work with a given germ, is it not plain that it knows exactly what the finished jiroduct is to be. 08 Proceed u^ffs of fiiditnid Aeadeuii/ of Science. Just what is ciifdldcd witliiii that KcriuV Wlu^tlioi' it is the ,e,erm of a horse, a (lot;;, a iu(iiilpt in the way of development and improvement. For instance, when the germ is that of a horse .has not the finished product heen at all times inimistakably a horse V Is not the Eohippus as ' certainly a horse as is the thoroughbred of today. True, some of the toes of the Eohippus. with their several toenails, have disappeared under the one liig toi'uail W(> call a hoof, hut do not the vestiges of the submerged toes remain to tell their story V ' I have watclied witli interest tlie zeal with which the search has been pro.«ecuted for the missing liidv tb;it it is said will confirm our Simian ancesti'v. and liaxc woiidt'red why, if this is true, nature neglected to l»r(>s(M\(' soiuc xcsligc of our lost caudal orn.nnient, some bint of the miss- ing vertebr;il a1 taclimeiil . I h;ivc wondci-cd if it v.crc in)t possible that instead of ;ill forms of life having (lc\ eloped from a single germ, that nature had not exhausted itself in pr(tdu(iiig one type of germ, but instead had been capable of producing and bad iiroduced innumerable germs, so that each separate type of oi-ganic life may liav(> bad its start in its own ]):irticular germ. I know it often li.-ippciis that men. in delving into their genealogy, encounter disagreeable sr.i prises. It may be true that we are only improved monkeys (with a))ologies to s.iue nmid^exs for some men). But if nature did not exhaust itself when it pidiluced the inilbii germ, m;iy it not be after all that the germ from which we aic (iescended was from its beginning a germ of humanity V Evolution must lie accepted, but not neces^ai'ily the meic guesses of the evolutionist. As long as it is a nu-re nuitter of guessing. I claim the right to guess for myself. It takes more than the Xeandertlial man. or the so-called Ape Man of .Java, to make valid the guess of our Simian ancestry. The beginning of mankind on earth doubt'.ess goe ■ back to an initial germ, but it is my guess that the pl;in tr.-iced in that Initial germ by tiie master arcbilect, and which was followed by the master builder, life, was always man, Man. as man, li.-is develoiied and is developing, but I decline to acknowledge kinship with either the migbt.x' Saurian, the e(|ui\dcal Simian, or the lowly i-ai'thworm. And now I venture one otliei- gross: Protoplasm is not life, nor is it any part of lite. It is simply the c(niductor (d" life. It is the vehicle through which life acts and with which it works. All this of course deals only with the visible, i)hysical world, and the visible, ])hysical universe, -tlu' world ;md the universe (d" i)hantasmagoria. of visible, changing, but tninsient forms. — forms which are simply the effects of causes beyond our ken.

As a cliief result, it is l.eiii- icali/.ed that snch te[ deiin<|ueney and crime was I'eehle-mindedness. I'.ut a very careful invest ii,'a tor has recently imhlislaMl data (the most accurate of its kind so fari sliowini: that the inmates of a cerraiii state ])eiiiteiitiary avora.u(' practically tlie same in iiitolliiii-nce as the .uciioral adult population. It was once sui)iiosed that most cases deixMideut upon charity showed a mental auc helow twelve and were to be considered feehle-minded. We now know that a "mental aye" of twelve is only very slii^hlly helow a\-era,i,'e in ineidal development. I'he result is that feelik'-mindedness is heiui;- used much less than formerly as an e\i>lanation of social dilliculties, and that research workers are turn- iuLC uKU'e and moi'e toward emotional and environmental factors in seeking; an exi>lanation for such social and economic mal-arljustment. And there is really a j^reat deal heinjj done, in a ([uiet Avay. in the attempt to measure the emotions. So I want you to think of the scale. coi>ies of which T have pa.ssed out to you. as hy no means a hit of freak research, hut as simjily one of a numher of efforts alon.i;- this line. The first test c(tnsists. as you will see. of twenty-live lists such as : dis^iust fear S(>x susi)icion aunt roar divorce dislike sidewalk wisisle naked snicker wonder spit fi^ht failure home rottins snake lin.s; prize jrutter thunder breast insult The subjects are told first to i^o Ihrouiih the lists and cross out everything that is unpleasant to them. Then after they have done this, they are told to ixo through the lists asaiii. and to draw a ciicle around the one word in each list which is nioxf unjiR'asant to them. The words are arranged according,' to a definite scheme: there are live sets of words, a sei-ies of .lokers and words chosen as un]>leasant to foui- different types of morbid personality. The selection of words has been nnide on the Itasis of ex- tended exjierience in work with the insane and with delinquents . ]*>ack of t!ie test is a lai-iiC body of t!ie(n-y with rei;ard to tlie neuroses; it is held by many writers that in such morbid c(iiiditions there is a marked increase in the tendency to emotionali/.e. and a tendency to transfer emotion from usual to unusual or associatenvk ol it (xiteric'uce with altnormal iKTSuimlilies ; it iiiis olivioiis lelatictus to cniaiii kinds of anxiety states. Tlie test, it should he added, derives ujost directly from a (luestioiiaire used l)y Woodworth iu studying iieiirotie indi- viduals in the army. And it is aimed to involve the content of certain types of (Udusion eounnon in menial disease. So much for the seitarate tests: in suunnariziuii- tlie total examination the total niunher of words erossed out is lirst sunuued. and is considered an indication of total atfectivity or emotionality. The deviations are tlien addi'd together, and the total used as an exi)ression of "total idiosyncrasy". Well — the tests doulttless seem to you vvvy crude — and so they are; they simply represent an etfort at lirst investigation of a suhject which has until recently heen all too nnicli neglected. I'.ut as an investigatory instru- ment the exaunnation has certain advantages whicii I would like to have you considi'r for a moment. 1 mentioned a moment ago Woodworth's (|uestionnaire. It consisted of questions such as: Have you worried ahout smoking? Yes. No. And the i^erson taking the examination was to underline "Yes" or "No" according as one answer or the other was correct. Putting the questions iu this way it required an 11x17 sheet to ask one hundred such questions. We ask one hundred fifty questions in a space 9x0 ; the total examination really asks six hundred questions all on two sides of a 9x12 sheet. The grea't condensation is ohvious. It is thus possihle in a very brief space to accumulate a large amount of data. But there are other advantages. There is no elaborate technique in giving the examination. All that is neces.sary is to hand the blank to the Ijerson who is to take the test and say. "Head the directions, and do what they tell you to do". It is thus possible for us to send out the blanks to other colleges and institution-; and obtain results which are strictly com- parable, so far as directions arc concerned, to the residts we obtain our- selves. Suppose for the moment you are taking the test. You do not have to write any answers. All you have to do is cross out certain wcu-ds or draw lines ai'oiuid them. The result is that the a\-erage college stueculiar choices made in circling words. So the examination is an extremely convenient method of obtaining information: those of you who teach will appreciate that an examination in which six hundred cpiestions are asked and answered in thirty minutes, and in which a first valuation of the results can be obtained in three minute-:, is .somewhat unusual. However, such an instrument is of little value if the information yielded by it is not worth while. The examination is intended i)rimarily. of course, for work with delinquent and with nervously altnormal individuals. And from such groups data are not yet available, though results from a number of reform schools, a group of colored peoi)Ie. a theological seminary, and a colony for epileptics will he ready soon. Results fnun a group of college students have, however, been analyzed to show sex diflerences. liriefly it may be .said that <*.4% of the girls lind more things unpleasant than the 74 Proceedings of Indiana Academy of Science. averajie (median) man. 5G% of the girls worry about more things than the median man. GU^/cof tlie girls consider more things wrong than the median man. The girls are distinctly more original tlian the boys in selecting the most unpleasant thing (G4% above the median man), but they are dis- tinctly less individual in selecting things to Avorry about (36% above. the median man). They are more original in their choice of the worst thing (G9% above the men's median). The results on the individual words are even more striking. The girls find words having any sex reference, or mentioning anything disgusting, much more unpleasant than the men do. The men on the other hand find particularly unpleasant such words as "disgrace, poison, persecute, unfair, failure". So far as worries go. the girls worry much more about religious topics than the men : they tend more to be depressed. The men stand out as worrying about their own health, as being distinctly hjiiochondriacal. These are simply interesting bits of fact, however. The important ques- tion is: can such an examination or questionnaire yield information which will enable one to distinguish the psychopathic or the criminalistic from the average individual, in soniething of the same way as scales for meas- uring intelligence are used to distinguish the feeble-minded? As was said before, data from patlu)logical groups are lacking. It was thought inter- esting, however, to determine how definitely the two sexes could be distin- guished by means of the tests. Briefly, it was found that the results in total affectivity and total idiosyncrasy were largely identical for the two sexes ; there was nothing distinctive in these totals. However, the 'four words on each test showing movt distinctive results (in choice of the word to be circled) w^ere found, and results (m these sixteen words alone were used. And it was found that in thirty percent of the cases an absolute dis- tinction could be made I In fact there was only one man who scored above the median for the women. It is at once suggested that similar valuable distinctions, in separating out the pathological and the delinquent, may be possible. At least it seems worth trying.

A recent cartocm depicted a trradnate .uroanin.s; under a load of books marked "'Knowledse" and unable to accept the volume of "Wisdom"' offered him. The wisdom and jud.t;ment s(>cnred from usinji this knowledj^e acquired, is lacking. Their knowledge is too ofien unorganized and discon- nected. They know their theories, jierhaps. but they do not know how to ai>ply them. We do not exiiect the universities to turn out men in four years who are capable of .solving hard iiroblems. but it is disciuu-aging wheji a chemist cannot prepare a sim])Ie soap witlumt being unnulely instructed, or when an engineer is unable to apply his theories to a bi-idge which dilTered from the one in the text. Is it the student's fault that he lacks I he (piality of Judgment V Kather is it not the result of how he is trained? Is ir not absuid to gi\f all the ect him when a grad- uate, to show initiative or creative power? Wh(>n a man has thoroughly thought out and woiUed out his first prob- lem in a logical manner, we find him able to ajiply his theories to the next with less troulile. It is not imposihle to teach a man h ;w to solve i>roblems when in the plant, but it is unprofitable and uiuiecessary if our schools are fulfilling their mission. The university is far better fitted to accomplish this than is the industry, for in the latter the student, now an employee, must lie a secondary consideration. 76 Proceed i II (j.'s of Indiana Acadcvti/ of Science.

The questionini;-. inventive, creative spirit must l)e ai-oused to a greater extent than it lius been in th(> past. To say that we haven't a place in our curriculum foi' >uch training, where the student may find himself, indicates all the greater need for a more fundamental rearrangement of our college courses. The sttident may have been fortu- nate enougli to have found the profession liest suited to his abilities, but very few find themselves in that profession. How can we overcome the prevalent view that a college training is a series of disconnected facts? Wouldn't the presentation of a gas engine to a group of freshmen engineers be of value in correlating numerous subse- quent pages of algebra, physics, and theories of dynamics? As most courses are now arranged, we have ample time to forget all l)y the time we are introduced to a concrete example of our profession. Again the realization that few chemical reactions go entirely as represented by the equation re- quires a rearrangement of the mental attitude of the chemist at a time wlien he needs to have his faculties at their best. It may be that our point of view errs. We do not aiipreciate all of the complexity existing in our universities, and we therefore do not presume to dictate any policy to otu- schools. We do look for results, however, and in- dustry makes its judgment on that basis — something seems to be lacking in our college trained men. After discussing the question of undergraduate research with representa- tives of the schools of Indiana, the Rcientech (Muh adopted the following resolution : RESOLVED: That the Scientech Club through its Research Committee exert its influence in promoting and encouraging a re- search atmosphere in the educational institutions of this state. As one means to this end. be it FURTHER RESOLVED: That efforts be made through the Re- search Committee for the inclusion, as part of the curriculum in all scientific courses of such institutions, of an approved thesis as a re- quirement for graduation : such thesis to embod.v the results of in- vestigation carried on during the fourth undergraduate year of study under proper faculty direction, and be it FURTHER RESOLVED: That in the fulfillment of such retpiire- ment. emphasis be laid upon the training of the student. The investi- gation should be designed to ground the student in the fundamentals of scientific inquiry, irrespective of the application of the study to industrial or other inun(>diate practical uses. Before proceeding further, we wi^h to enqdiasize the fact that we realize how essential is the cordial cooperjitinn of the heads and faculties of the educational institutions of Indiana.

IOWA AND :SIISSOrRI. 1. Purpose. An intensive study of the prehistoric population of the Mississippi Valley. The initial approach to this problem is an archaeological survey of the states of Illinois. Indiana. Iowa and Missouri, with a view to determining the different types of the remains of the prehistoric i>opulation. togetlier with their distribution, so that it may be possible to publish an Arcliaeolog- ical Atlas for each state, comparable with tluit issued for the State of Ohio. On the conclusion of the Survey it would be (lesiral)Ie to exciivate. at least partially, two or three tyix' sites in each state, to confirm conclusions as to cidtnral attiliations and clironological se(|U(>nce derived from the data of the Survey. State Surveys have been instituted in the neighboring States of Ohio. Michigan. Wisconsin, and Miiuiesota. Those in Ohio and Wisconsin liave so Proc('((liii(/s of l,i(]i(iii) Such a survey is the hrst necessai-y step in the conservation and lireservation of the State's anticiuities. Its lojjlcal end is the establishment of State Parks in which arc to be found typical mounds, hill forts, etc.. and also the encouragement of State and local museums. The development of automobile travel has brought the need of State Parks which shall have in themselves some worthy intrinsic interest. The State of Ohio has shown what an asset such parks can bi". for exanii>le. the Serpent Mound. Fort .\ncient. etc. The Survey herein ])roposed is es-cntially to take stock and to see what the State possesses in the way of autiriuitles so that it may take the proper steps to preserve such of tlies(> as ikisscss great public interest. (4) Many States are now enacting laws on the preservation and i)r()- tection of auti(piities. Eventually your State will be confronti'd with this problem. The liandling of this problem will require data from such a sur- vey as herein proposed, for without exact knowledge of what your State possesses intelligent action cannot he taken.

The bird was very sliy and usually saw you first, departiu},' hastily as you approached. 1 trami.ed over the island every day in the early morniuff and found the bird only when the swish of his big wings told me he was leaving, antl as there are about JO miles of canals and in- land lakes on the island, it was (piite a task. I also saw one bird flying high another morning that spring. In the fall of that year I saw no swans although hunters told me that a few had been seen at the Flats. But one morning in the spring of lUlO I saw two swans resting on the main channel of the Detroit River immediately .south of Belle Isle. They discovered me almost at the same moment and rising flew swiftly toward Dake St. Clair. their great wings flapping and their feet pjiddling the water as they went. Later that same morning as I was tramping throu.gh the woods at the uiiper end of the island I heard the plaintive notes of a number of swans, distant but coming nearer, a sound familiar enough in my childhood when 1 lived in Northern Michigan and swans were so common as to excite little interest. The weather was cold and foggy, with no wind or perceptible air movement: and the birds, flying low. merely skimming the tree tops, came directly over me; and I had a si>lendid chance to observe their for- mation. There were 25 birds in the long wedge-shaped flock. 10 individuals on one side and 15 on the other, each bird equally spaced from the other and each line as accurate as though spaced and limned by the hand of a master. The birds were honking sonorously, my ear catching generally ab(.ut three notes, one very low and two quite high. The higher notes pre- dominated. I spent the day on the island. The fog lifted soon. All day swans were flying back and forth showing that they were not in migration but had stopped to rest and feed. At one time I counted TO birds in the air, the biggest flock containing :!5 birds flying in two long V-shaped lines, the others being in lesser flocks and flying singly. The largest flock that I saw that day contained about 200 birds flying in a long zigzag line quite like a huge piece of rickrack lace stretched across the sky. From the first week in March until the middle of April swans could be seen every day. sometimes on the river, more often on the wing: and lh(\v were as abundant at the Flats as Canada ( loose which are always 84 Prorcc(rui(/-s of fiidhiiKi Aciidciitij of l^ciciice. quite coiiuiioii in tluit vicinity I'very ^pi-inj;.

Tlie inter- estiiiiT work of Snyder (1. .".. {',. 7. lit' and Thompson (11-14 inclusive) l:ear out this statement. The present paper deals with oiiservations (m these insects with special refeience to their economic aspects. I'ntil recently there has been a ten- dency anuin^: eiitomolcjrists to re^'ard the termites of the T'nited States, cast of the Mississippi and north of the Ohio I'ivcr. as (»ne species, namely IfctirulHeinicx {LcucotcrmcH) flariix-s KoUar. This is in spite of the fact that Snyder and lianks (1. (I. 7) have pointed out that there are two oilier species of the same uenns h'cticiililcniics namely h'. Iitn/oii Banks and /*. ririnniciiH Banks whose ran.iie in this country are at present not W'ell defined. These two species were both found and described since 1907 from Falls (Jhurch. Virginia, a few mile.s from Wa.shington, I>. ('. It should be pointed out that this region is one that has literally been "combed" by entomologists since the formation of the I". S. Department of Agriculture. It is therefore quite possible that intensive work will reveal not only the presence of R. hagcni Banks and R. virf/iiiicus Banks over a wider area than they are now known to occur but also the presence of one or more new species. Disirihiilion of Termites in Indiana. Reficulitermes flaiipe.s Kollar is the only species that until the present lime has been recorded in Indiana. Snyder (7) records it from the vicinity of South Bend. Indianapolis, and .Teffersonville. During the past season Columbus and Lafayette have been added to this known distribution. Reficulitermes Virginians Banks was collected for the first time in Indiana at Indianapolis on July 1. 1020, by the writer. The forms collected were winged colonizing adults. The nearest point to Indiana from which this s])ecies has been recorded is Okolona, near Louisville, Kentucky (Banks. 1). Reticulitermes hagcni Banks probably occurs in Indiana, though the near- est point to our State from which it is recorded is Kane, Greene County. Illinois (Banks, 1). t^ivarming. There are two times when termites are rejwrted to the Division of En- tomology. These are as follows : First, when the annual swarming of .■u Pubhshed with the permission of the Cliii'f of tli." Division of Entoninloirv the Director of the Department of ConseniUioii of Indiana. -The figures in parenthesis refer to the Literature cited. 88 Proceedings of Ti)Olav.a Academy of Science. the winged colonizing adults takes place (males and females) ; secondly, when the characteristic damage that these insects do to buildings and thcii- contents or to living plants is first noted. Fifteen reports of swarming or injury were obtained this year and in eight cases specimens were collected all of which proved to be R. flavipes Kollar. The first swarming of termites this year was on February 29th. This was in a house in the northern part of Indianapolis. The time of swarm- ing was 4 :00 p. m. and the temperature out-of-doors was 50° F. and indoors about 70° F. No specimens of this swarm were obtained and no subse- quent swarming took place. The second swarming was in a factory building in Indianapolis on March 5th, 1920. The temperature out-of-doors was 10° F. and there was six inches of snow on the ground. The indoor temperature ranged from 50° F. at night to 70° F. and over in the day time. The swarming here took place between 8:30 and 10:00 a. m., the maximum emergence occuring about 9:00 a. m., and occurred daily at this time for four successive days. On March 15th and April 5th R. flavipes swarmed in the Experiment Sta- tion Building at Purdue University at West Lafayette. Specimens of the April 5th swarm were collected and forwarded to the writer by R. W. Hosmer of the Bureau of Plant Industry of the U. S. Department of Agri- culture. The first out-of-door swarming of R. flaripes recorded this year took place in the southeastern part of Indianapolis simultaneously with an indoor swarming at the same locality on April 21st. From the location of tlu' points of emergency indoors and out-of-doors there is no doubt that this swarming was from the same nest. It took place daily between 8 :00 anc: 9 :00 a. m. over a period of three days. This swarming followed a heavy rain of 2.3 inches on April 20th and a total rainfall of over 3 inches between April 17th and 20th. The next out-of-door swarming in Indianapolis occurred on May 26tli at 11 :00 a. m. and in the same locality, but from a different nest, on June 3rd about an hour earlier. Only a single swarm emerged from each of these nests. The swarming on May 26th was not directly correlated with any rainfall but that of June 3rd followed a heavy shower on May 31st. Snyder (1) following the phenological work of Hopkins (2 and 3) shows that the fir.^t swarming of 7?. flavipes is correlated with the blooming i. e. ripening of the pollen of the large flowering dogwood Cynoxylon (Cornus) floridum Linn. This is based on six years' observation. However, in Indian- apolis the first out-of-door swarming, April 21st, occurred almost two weeks before dogwoods bloomed and the second and third, May 26th and June 3rd, out-of-door swarms occurred two weeks after all dogwoods had dis- appeared. At the time of the second and third out-of-door swarming dates, grai^es and blackberries were blooming. No fall swarms of R. flavipes were reported this year though in 1919 this occurred in the house where the spring swarming took place on April 21st. The only swarming of Reticulitermes mrglnicus Banks observed was on July 1st. The winged adults were seen flying across a large vacant lot between 9:30 and 10:00 a. m. It was a clear bright day with a high rela- tive humidity and temperature. This swarming occurred a month after Ilic lasl sw.'inii iiiLT 1 .r /.'. lln /•//,. .s K., liar and at a J,iii( Icii 'l'ili(/ nil icric IIIKl I.iii II was ill fnll bloom. Vi ■erfectly under- stood, are: ll) the kind of reproductive forms in the colony; (2) the a.ge and size of the colony: and (.'5) the influence of instinct. The role of swarming in the life economy of a colony is another point of interest. In the case of early swarming indoors the value of swarming is hard to see as i>ractically all the adults emerging, if they are not killed, lierisli. 'i'his is because conditions necessary for the establishment of new colonies are seldom present. Out-of-doors the opportunities for the found- ing of new colonies are greater. But even out-of-doors immense numbers of colonizing adults perish. On May 20th ])ractically all termites R. flavipes rliat emerged were eaten as soon as they issued by a large flock of sparrows that gathered for the oc asion. In the swarming of R. virc/inicKS on July 1st it was observed that adults alighting on the ground were immediately snatched up and dragged off by the workers of the common corn-field ant L«.s-/».v /)///(■/• Tjnn. var. jmcricaiiit-s Emery. Termite Injury. The injury that Indiana termites do is of two kinds, namely that which is done to buildings and their contents and that which is done to living l>lants. The mendiers of the genus UcUcuUtcrmes are subterranean in- sects. Tender normal cnnditions in nature they feed on stumps, logs, and wood debris, straw, inaiinre, and leaves. P.ut with the advance of civiliza- \w\\ much of the food of termites has been removed, forcing the insects either to retreat before this advance or to adapt themselves to the new order of things. They have cho~en the latter course to a certain extent, at least, as is shown by the injury they do to living cultivated plants and to buildings and their contents. Tlies(> insects are justly classed among our most destructive wood-boreis. There is one thing that is ab.solulely essential for a colony of Indiana termites to nuiintain itself and that is a ready access to moisture. This is olitained from the ground. Given a cimstant supply of moisture these insects are able to tunnel in the comparatively dry woodwork of buildings 90 Procc('(1in(/s of hidhnin Acddou}! of Science. (.r into its coiitoiits a .urcat distance so that the limits of a colony are hard to detine. It is therefore api>arent tliat termite injury to buildings and their contents is intimately correlated with the construction of such build- ings. This is borne out by the fact that new buildings as well as old ones are subject to attaclc. As has been said before, the swarming of termites in a building sliould be regarded as a danger signal though it is not an in- fallible one. because a building or its contents may be infested and no swarming occur, in which case the hidden work of the insects might escape notice until irreparable injury is done. Some examples of the damage done to buildings in Indianapolis and a fuller discussion of the damage done at the Columbus Pulilic Library well illustrates certain things that should be avoided in the construction of buildings. The popular cement floor of porches, unless i)roperly constructed, offers a means through which, termites may gain ontrance to the frame work and weatherboarding of houses. The gi-out of cindei's and gravel are often placed flush against a wooden beam and the cement is l)rought flush with the weatherboarding. Tonally in time there is a decided crack between the cement and the wood, allowing watei' to enter when the porch is scrubbed or during hea^y rains. Tlie cinders and gravel grout are no repellant to the termites as there are usually sutHcient holes in the latter through which the termites can work and thus gain entrance to the wx)od. Three such cases of injury have been obsei'ved during the past season. In the case of the factory building wlK-re swarming occurred on March oth it was found that the floor of the othce was laid dirt'ctly on a bed of cinders and the wooden walls which separal^'d the oltice from the rest of the building were flush with these cinders. Likewise, the lL'xl2 untreated yellow pine pillars which supiK)rte(l tlie roof were set on stones one foot oeneath the surface of the ground. Three years pi-evi(Misly the floor had been removed because of termite damage and replaceil with another wooden floor. It is needless to .say that the conditions for termite injury were ideal. Not only the floor Itut the walls and a mnnhei- of the pillars were badly damaged. In a dwelling in the northern ])art of Indianapolis termites had gained entrance to a "built in ice box", the wood of which was constantly moist and from this source had riddled .several of the beams supixirting the house. At another place where the weather hoarding of the kitchen was flush with the ground this was badly damaged. At the Columbus Public Library termites did the worst and most extensive damage that has so far been recorded for these insects in Indiana. Three hundred volumes of books were so badly riddled that they were a mere shell. The wooden racks in which tiiey were kept were badly damaged and all baseboards, door casings and moldings oil the first floor of this building were more or less infesteil making their removal necessary. Even pictures in contact with the molding were ruined. This building is of lime- stone, two stories high, and is what is connuonly known as "flre proof" in its construction. It sets on an embankment about three feet high and is so built that the floor of the flrst story is slightly below the level of the em- bankment (See Diagrammatic Cross-section of Building.

The upper floor is used for a readiui;- and for the "stack" room. Originally the floor in the basement was yellow pine laid on joists em- bedded in the ground so tliat the floor itself rested on the ground. Like- wise, the lower edge of the baseboards and tlie bottoms of the door sills rested on the ground. There was a wooden wain-coating, about four feet high, around the room. The bottom of this wainscoatiug rested on tlie ground. Four years ago this floor and waiiiscoating were removed because they had '•rotted", and there is litt\' doubt that the "rotting" was caused by termites. As i-! shown in tlie diagrammatic drawing. Figure I. B.. the wooden floor was replaced by one of cement and a piaster wainscoaiting laid on patented steel wire latli was used instead of the wooden one. Had the work l)een done right at tliat time no frrlher termite injury would have been po'-'sible. But instead of eliminating all wood in contact witli the ground and bring- ing the cement floor flush witli the p'.astt'r wainsc:)ating. unfortunately, as is sliown in the drawing, both the bottoms of the baseboards and cioor sills were left in contact with the gr>un(l instead of allowing them to rest on the cement floor. Further, the plaster wainscoatiug instead of being flush with the stone walls of the building is supported by yellow pine beams in con- tact witli the ground. Some of these beams come in contact with the casings of the windows of the flrst floor and all of them are in contact with a yeUow pine molding that tops the wainscoatiug four feet from the floor. Of course, the baseboards and door sills were badly damaged (See Plates J and II). By means of the joists suppnrtlng (be waiiiscoating as well as the characteristic "covered runways" on the hack of the wainscoatiug the termites had worked into the nioldiu'^ and frcMu it into the pictures and their frames.

The third report of termite injury CMiue from Iiidianupolis on August 27th. A backyard gardener wondering wliy his sweet corn did not yield as it should dug up some of the plants and found the lower parts heavily infested with termites (See Plate II. B.). Over IHO feet of row were thus damaged. Specimens submitted were 7?. ftariix'.^i Kollar. Taken as a whole over the Ignited States termite injury to living plants seems to be increasing due no doulit to rbe fact that their hcunes. such as logs and stumps, are rapidly disappearing liecause of the practice of clean cultivation. As a result the termites are forced to seek elsewhere for suffi- cient food and their attacks on living plants are one way that they are meeting the exigency. On the other hand it should be pointed out that keeping areas on which plants are grown free from decaying wood and otlier debris on which termites can exist is necessary if damage is to be prevented (See Nougareti 4) as such debris is often a source from which they start their attacks. A cknoK'lcdr/emcn ts. The writer wishes to acknowledge the kindness of Dr. T. E. Snyder and Dr. W. M. Mann, of the U. S. Bureau of Entomology, for identifying or verifying the identification of all termites and ants mentioned in this paper. SiMnmari/. 1. Two species of termites RefwuHtermes floripes Kollar and ReticuUter- mcH virghiicus Banks are known to occur in Indiana. A third species Rcticiilitcrmes hageni Banks will probably also be found in this State. 2. The interesting phenomenon of the annual swarming of the winged cohmizing adults of R. flavipes occurs indoors as early as February 29th. Out-of-doors it occurs over a period of over a month. April 21st to June 3rd. The swarming of R. rirginiciis takes place out-of-doors a month later than that of 7?,. flavipcx. o. Sparrows iind ants have been ol>served preying on these winged cohin- izing males and females. 4. Termites damage buildings and their contents and their attacks on living plants are increasing. This is the way that termites are adapt- ing themselves to the advance of civilization which has resulted in the removal of much of their food, such as logs and stumps. Litryaliin Cited. 1. Banks.

A few days later Mr. Boss informed me that the surface of the lake was strewn with fragments of medusae. All specimens examined were females. A few specimens were found the previous summer. During the summer of 1920 the lake was watched carefully from .Time twenty-first until October s(>cond. The hydroid was found June twenty- eighth (m material collected June twcnty-tirst. These hydroids were ob- served to form sausage shaped buds which separated from the parent and formed new hydroids. Other buds remained attached, thus forming col- onies. The largest colony found hail seven hydroids. A third type of bud formed the medusa. The first medusa in the siuunicr of 1920 was taken July sixteenth. It was about one-half inch in diameter. The rest of the summer they were alMuidant, but not po numerous as they were on my first visit of the previ- ous year. Again all the medu ae wer(> females. This, along with the fact that on previous discoveries of this medusa all the specimens were males, has puzzled me somewhat. The females became sexually mature and shed their eggs but they did not develop so far as my ob'-ervations went. IMank- ton catches at all seasons and depths have shown no free swimming larvae. Xeither has a close examination of the weeds, sticks, stones, and surfaces of boards and posts shown anything of the sort. Kut why is there only one sex? I do not know- but the facts lead me to wonder whether the hydroids may not be male and female producing. How the forms got into the lake is doulitful.

On August 2G. 1917, two friends and myself hunted Maeromias along the Wabash River above Bluffton. It was a cool windy day. altogether unfavorable for Maeromias but we took an even dozen— height of pavifica. two of wabashensis and two of illiiioiensis. One or tn^o identified on the wing as tacniolata were not captured. One pacifica was found crippled and unable to fly in the weeds along the river; one hind wing was broken at its base in the thorax and the body juices were exuding. Another of the same species was floating alive on the water with the front wing broken off near the base. It is in-ol)able both injuries were caused by birds. At Howe. Lagrange Co.. on Sei»t. ."!. lOlO. I was asked to identify the birds which had nesteil in a bhu' bird box in the hotel yard during that year. A description of the birds liy my informants left no doubt that they were great crested flycatchers. The birds were new to the Ijarties observing them and the feeding of the young was e-pecially inter- esting. They reported that they never saw the old birds carry in any other food than large dragonflies. An examination of the nest showed a quan- tity of bits of dragonfly wrings and legs. I was able to identify a bit of wing of LihclhiJa pulcJiella but the bulk of the material was parts of Maero- mias. There is no doubt that dozens of thee insects had gone to supply this one nest. Martins are very numerous in boxes placed for them in Bluffton. The birds spend many hours over the river and the abandoned adjacent quarries near Bluffton. That they feed on large dragonflies is no question though I have been able to certainly identify only LiheUula pulchella. But in many years' collecting along the Wabash I have seen only one Macromia near Bluffton. On the other hand, Clomphm occurs within the city limits in apparently as large nund)ers as elsewhere. But the Gomphi have a relatively short se:is(!nal range, they burst their exuviae by hundreds or thousands almost simultaneously, and their eggs are laid and their aerial life ended before their prechu-eous enemies could gather in numbers to attack them. The longer seasonal range of Maeromias, by reason of which the brooding mother bird and later her offspring, from hatching to leaving the nest, could be fed on this one species of insect, obviously invites danger. The ijair of great crested flycatchers at Howe doubtless became expert Macrt)mia cateheis by the time their offspring took wing. 85. Macromia taeniolata Ramltiu-. At a bayou two miles west of Merom.

On Sept. 1:5. 1914. the following four species of Fiympcirum were tiying at this pond: nmhiguum. ohtrusum. riihi- ciindiilum and vicinum. Obtrumim and rulnciiudHJum were about in equal numbers and were much more numerous than the other two. Of fifteen males and two females of ruhiriiiKlHluin' taken, all but one male were of the yellow-winged form. On Sept. 2. 1917, ten males and three females were taken at this .same pond. Of these males two had clear wings, five were yellow winged and three were intermediates. All the females were yellow-winged. At some deep partially shaded gravel pits about a quarter of a mile distant, foni- males taken the same date were ;ill clear win.ged. I have noticed at other i>laces than this intenuban pond that the yellow- winged form occuned about shallow warm pools or was seen late in the season when ponds were at low water stage, and I believe thei'e is some relation between light or warmth, or both, in producing this color form. 115.

Of the fifteen species thus eoinpi-ised. we ha\c exaniiiied all hut t wo - Xijroca innotdta and Nyrocd iidtioiii. Study of the structural characti-rs of these birds has resulted in the discovery of some hitherto unnoticed char- acters, which indicate that to include all these species in a single genus \v(Uild be manifestly improper, and that in view of important differences, some additional genera need recognition. The characters liere used as generic-ally diagnostic are constant and trenchant so far as it has been possible for us to verify them, and a number of other characters we have omitted because they fail to come up to this standard. It is becoming fairly well understood that many differences that are apparently good generic characters fail when several individuals of a s])ecies. or when species of other supposed generic gron])s are critically examined: and while a mere ahnormality in a single individual can not he lield as invalidating a gen- ei-ic character, it is ((uite evident that a character which is not i>raclically constant in all individuals of a sjiecies can scarcely he nsahle in the diag- nosis of a genus. It is evidently thus unsafe to base generic characters on examinati(m of a single six'cimen of a species, hut sullicient examples should he exandned to eliminate the factor of individual variation. As in many ducks, so in the liirds at present under consideration, the form, shape, and l>roportions of the bill are of prime importance as tlie indicators of generic relationships. Of other characters made use of in the present conni'ction. tho.se of the relative proportions of the wing and of iinier toe with claw, compared with the exposed culmen. are apparently of most importance. While coloration as a i»rimary geneiic cii;irac(ei- is of little or no value among these ducks, it is of interest to note that the generic classification 106 Proceedings of Indiana Academy of Science. heri' adopU'd i-drrcspoiids fairly wc-ll with the general coloi-ation of the species concerned, although Xi/rocti bacri is, of course, an exception. Fur- thermore, the sequence of species is virtually the same as that adopted by Mr. N. HoUister in his recent notes on the relationships of Fuligula col- laris,^ except that, of course, the sequence is reversed. The measurements of which use is made in proportional comparisons in this paper have been taken as follows : Length of wing. — The distance from the bend of the wing to the tip of the longest primary, taken with dividers without straightening the quills. Exposed culmen (length of bill). — The chord of the culmen. taken from its tip to the point where the feathers of the forehead impinge on its base. Height of bill at extreme base. — The distance in a straight line from the highest point on the base of the maxilla to the nearest point on the ramus of the mandible. Width of bill. — Measured with dividers at the widest point near the end of the bill ; at base ; at point of greatest width ; or at the posterior end of the nail where this coalesces witli the culmen. Length of the nail of bill. — The chord of the dertrum. measured in a straight line from its tip to the point where it coale.-ces with the culmen. Inner toe with claw. — Measured witli dividers along the upper side from the middle of the joint between the metatarsus and the inner toe, in a straight line to tlie tip of the claw.

Remarks. — This, the type of this monot.vpic genus, is very much more different from the species above included in Nyroca than authors have here- tofore realized, largely because its distinctive characteristics have appar- ently been unappreciated. Its separation now as a distinct genus is based almost entirely on new characters. From Nyroca it may readily be sepa- rated by the deep longitudinal cavity at the base of the culmen. squarish tip of bill, and in having the width of the bill at the posterior end of nail at least 2 1/2 times the length of the nail : tip of maxilla less strongly hooked; nail of bill relatively narrow and strap-like: and the height of bill at base 1 1/4-1 3/8 times the greatest width of bill. 112 Proceedings of JiHliana Academy of Science. Tliis yciius in some respects resembles Aristoiictta, as for instance in the much concave base of culmen. in wliich character it differs from all the other groups here considered. It is, however, well differentiated from Aris- tonettu, as may be seen from the diagnosis under that genus. The generic name Aythi/u Boie' is the earliest name applicable to this group, but it is preoccupied by Acfhya Dumont,^ wliich is a synonym of Aethia, the earliest name for the genus of Alcidae formerly known as Simo- rhynchiis. The Aifln/a of Boie-' is. of (Mur.-e. nu-rely an emendation of Aiithyn Boie. and is also preoccupied by Aclliya Dumont. Likewise, FtilU/uhi Swainson,* the type of which by monotypy is Anas ferina Linnaeus, is pre- occupied by Fiiligiila Stephens."' The name Aithyia Gloger," proposed as an emendation for Aythya Boie. is, however, by virtue of its additional syllable, a different word, therefore tenal)le under the present rules of nomenclature, and should be brought into use for this genus as its earliest valid designa- tion.

As no snake chews or rends his prey, we knew that it passed his IkvkI and throat entire. The eidar.ucment did not dis- appear for a week. "Loug Tom", a giant Ueticulnted python {I'tjlluiii rcticiilittiix) . fed on a pig weighing forly-Hve pounds. We wanted to get some photograph.s of the monster rei)tile taking laige pre.\. so the piu was put in the den alive; but as his prey had heen killed fut still warm. We have, however, fed them with cold-storage rabbits that were killed in Australia. :\Iiss Crace Clark. ;i young woman with much experience with l)ig snakes in shows, tells me that she once had a snake that would take a chicken after it was dressed and cut into pieces, receiving the pieces one at a time. One evening we wanted to feed a very larso pigeon to a small Indian python. In order to .save him the trouble of working over the shoulders, we cut otf the wings. After gorging the bird, we otTered him the wings, which he took and swallowed. The inthon which swallowed the pig was received from Carl Hagenbeck of Hamburg. fJermany. in July. 11)07. ^Ir. Ila.irenbeck had a photograph of the r(>ptilo in the act of swallowiivir an Indian antelope (Antelope cervi- i(il>ni) weighing ov<"r ninety jMnuids. lie had another Tieticulated python which swallowed a innet.\-seven |)oun usually seizes the pig near the head and throws his coils about the Nlioitblcrs. The posterior limbs are thus left free, and with these he fights desperately till life is crushed out. frequently, as is plainly evident, doing sericms damage to his assailant. In conformity to their attenuated form, snakes have a large number of vertebrjo and ribs. A peculiarity of the skeleton is that there are but two cervical vertebrae. The atlas and axis, or first and .second bones of the spinal column, next to the head, licar no lih. but they start with the third vertebra. Neither are there any lumbar or sacral vertebrae. In the Reticulated python there are 3(51 vertebra. Of these. 2 are cervical, .37 caudal, and 322 dorsal. The caudal vertebra- all bear transverse processes, the proximal ones long and broad, diminishing gradually toward the tip of the tail, but they do not disappear, even in the last distal vertebra. It may be that these are but ribs ankylosed to the vertebr^e. It is sometimes difficult to distinguish just where the ribs end and the transver.se processes begin. This is true of the Indian python. As already intimated, there are 322 pairs of ribs. However, it is highly probable, at least possible, that this number will not hold constant. Even in man there may be thirteen, eleven, or as few as nine pairs. At least one human skeleton has been known with twelve ribs on one side juid thirteen on the other.

It is always danserous to go near these bii; snakes with the smell (d' any kind of bird or mammal on the hands or clothiuir. When they are liuiiixry and scent their natural food, they will strike at the tirst tlnui: they see moving. They will even strike at inanimate objects \\hich ha\e come in touch with their natural ])r(>y. One evening we were feedin.^ a big ])ython. For some reason he had dropped the prey, and to get him to return to the chicken, I picked lip a woolen duster which the janitor liad been using to dust the glass cases, and pushed it towards his head. Instantly he struck and seized the duster in his teeth. His jaw^s had to lie pried oi)en to make him let go. T'nder similar circumstances a python in the Philadelphia Zoological Garden a few years ago. seized and swiillowed a lilanket. After retaining it for two days, he disgorged the article, rolled into a compact wad. The sense of taste in the serpents is very keen. If chickens are kept in a dirty box, these reptiles will refuse to feed on them. If a python bites into the crop of a chicken ccmtaining bad-tasting matter, he will drop the chicken. To test the sensibilities of the serpents, we once put a stale Q^i:. in with a Black snake. This species (Boscanium comtrictor) is \('ry fond of eggs, but no sooner had the shell broken in his stomach than tlie littl(> fellow commenced vomiting, and continued until the stomach was completely evacuated. It is sometimes said that tli(> snakes have no eyelids. In fact the eyelids are fu.sed in a transparent skin over the eyes. When they shed they shed the skin from over the eyes as well as that from other parts of the l)ody. •lust before the old skin is removed, it dies. l)ecomes dull in color and opaque in texture, so that for several days before shedding a snake is almost blind. There is a nnlky fluid between the dying epidermis and the newly forming skin beneath. It is a strange fact, hut dui-ing the last few hours this fluid disappears and the skin over the eyes partially clears. As .soon as the old skin is removed, the snake is able to see again as well as ever. r.ttt it sometimes happens, in captivity, at least, that the skin over the eyes is not renioveenny, Giebel, Piaget. Taschenberg and others, continued the work witli excellent results. Most of this early work was along taxonomic lines, that of describing, naming and classifying, but a few men, Kramer, Melnikoff, and Grosse did some work on anatomy. The work of Grosse in itself was not of a high order. No special attention was given to accuracy of description and draw- ings, consequently the work was crippled somewhat imtil our modern entomologists revised and improved upon it. In this country Herbert Osborn and A. S. Packard did the first work of any consequence. Osborn's "Pediculi and Mallophaga affecting man and the Lower Animals" was the first real attempt in this respect. It was by no means complete. Much remained to be done. It was at this point that Vernon Kellogg took up the investigation of Mallophaga. He made ex- tensive collections, aimed at completeness in every respect. He made col- lections from most of the common birds of ]yorth America. Special atten- tion was paid to classification, to accurate descriptions and very accurate drawings. The internal anatomy was completely worked out. Furthermore, the old Nitzschian nomenclature was revised and brought up to date. In every way the work was of a higli order and set a new standard in Mallo- pliagan lines. The position of Mallopliaga among the Insecta for a long time was a much-debated question. EacJi new student quite naturally shifted them from one position to another because little was known then concerning the anatomy an/)li condied out. oidy the loss of lofis of the lice may result. So even if hand picUini;- is tedious, nevertheless, it is the liest method. The regions on the hinl in wliich the lice ai'e found are detinite and lunc some significance attached to them. For instance, a very rai>id running louse like Menopon or < 'ol])ncephalnni will he found in the anal regions or .>n the back, lint sncli a slow one as a 1 >oco|di(U-us will he liniiteii lo the head or neck entirely. There are reasons t"or Ihis (uienlalion. 'I'lie hird can not easily scratch off a heavy-.jaweil and heavy-clawed Kocoiihorus from the neck region. n()r will a limiled ainounl id" dusting do much good in that region. So also will a ('oliioce|ihaluni (■■-(•ape if the hird attempts to catch it with its hill in a region. Lipeurus quite often is found among the wing and tail leathers. Trinoton. which is very agile and strong of foot infests the back. Whether these obseiwations correspond with those of others. I do not know. for none are recorded. In collecting lice in the lield the usual method employed to preserve them is that of placing them in 75 or 80 per cent alcohol. There is slight .shrink- age due to hardening effects of the alcohol, but insufficient to cause any serious damage or to interfere with subsequent study. I.ice may also bo preserved in a solution of chloral hydrate which will keep them quite soft. From much material one is enabled to make satisfactory studies. Other methods more exacting can be employed if facilities allow. Lice that are lire.served by the above named methods can he i>ut through a technique which will yield beautiful preparations. If it is possible to collect the insects alive. tlie.\- may he placed in hot water — very nearly boilin.g. This will ha\(> a two-fold elfect. When thrown into the water they will tloat. consequently their legs will be extended very nicely. In this condition they will be killed by the hot water. In subse- (luent dehydration, from 70 i>er cent alcohol through 80 and 95 per cent alcohol the extended condition of the legs will be practically unchanged. f(.i- they will have become suthciently hardened in 70 per cent alcohol. From ur, per cent alcohol we transfer them to absolute alcohol. The usual method following this is xylol and balsam, for the permanent mounts. This 122 Proccr(Un!/s of liKJiajia Academy of Science. will give excellent preparations, which are strilvin^ly clear, if no air or water remain in the insect. Another methofl. simpler and decidedly quicker is to mount the louse directly from absolute alcohol into Euparal. Euparal as recommended very highly by Lee. is a mounting medium whose index of refraction varies to such an extent as compared to that of the cleared louse, that it allows very minute structures such as pustulated hairs to be seen very distinctly and advantageously. Another advantage in this technique lies in the fact that xylol is not needed as a final clearing agent and less shrinkage results in the insect. Moreover, the expense of xylol is entirely eliminated. Such mounts will allow the internal anatomy to be seen in part. If the internal anatimiy is not desired jiarticnlarly a still clearer specimen can be obtained. If the louse be placed into caustic potash or caustic soda previous to the final steps in deh.vdration. all internal structures that cause some opacity will be dissolved. It usuall.v requires from 0 to 12 hours to completely clear the specimens after which they should be well washed in water before the final dehydration is undertaken or certain colloidal precipitates will form later. Moreover, the procedure .iust described will enable one to straighten out all legs, which had been drawn under the body during killing, whether directly by alcohol or hot water. They become quite soft in the potash and are somewhat easily handled. Some precautions are necessary in the final mounting into Euparal in order that the air ma.v not enter the legs and abdomen of the louse, and cause it to become entirely opaque. To overcome this requires care not to expose the specimen to air in removal from the absolute alcohol to the mounting medium. If. after some time, siich mounts in Euparal develop peculiar polygonal crystals, they can be removed by gently heating the slide over a flame or in an oven. These crystals are camphor which has crys- tallized out and which was one of the solvents of the resin used in making Euparal. i. e.. — Gum Sandarac. The species-determining characters in lice are many and varied. In the main, they constitute the greatest ditficxdty in the study of lice and require considerable attention. The nomenclature of anatomical parts of lice in this pai»er is that followed by Kellogg in his New Mallophaga I, (1896). The head of a louse may be said to consist of two main parts. The front which includes the clypeus. and the large swollen hindpart or occiput. The fi-ont and occipital regions are usually separated l)y a groove or fossa in which are situated the antennae. This is the antennal fossa. The lateral margin of this region is called the temporal margin and the posterior margin ad.ioiniug and touching the prothorax is the occipital margin. With- in this swollen occipital region are found bands running from the base of the occipital margin to the inner end of the antennal fossa. These are the occipital bands. Those bands running forward, well into the front and arising at the antennal fossa are the antennal bands. The broad colored, chitinized plate between the antennal bands, is the signature. In some gen- era, as Docophorus and Nirmus, there arise at the lateral margin, and ad- joining the antennal fosa, certain large movable spine-shaped structures.

There is a uniform number of hairs present in tlie tcm])oral and oecipital margins. These hairs, as well as those of the prothorax, raetathorax and abdomen are used as determining eharaeters. as their number is uniform. Whenever these hairs seem to i>roject throush a elear space in the colored chitinized parts of the in.'^ect. they are said to be itustulated. Differences in penera involve uxire than the aforenientioned fads. It depends mainly on the shape of the body, the size (if the trabeculae. whether movable to any marked degree : upon the size of the front as compared with the occiput: the depth of the antennal fos.sa or ocular emargination, and the size of the temporal margins or regions of the occiput, generally indi- cated as swollen temporal regions. Another genus distinguishing character is the similarity or dissimilarity of antennae in both sexes. There are other differences in genera which will be noted in the accompanying key. It is the key as revised and standardized by Kellogg from his New Mallo- phaga I (1896) pages 61-62. Key to the Suborders. A. With filiform 3- or 5-segmented antennae, and no labial palpi.

All birds as will be seen, are migratory birds except one, the English sparrow. *i .\ list of species found on a number of birds is given herewith. There was absolutely no straggling of lice from one bird to another as might be the case if the birds were placed in one bag. These lice were collected in the field, that is, as soon as the bird was procured, they were picked and preserved in vials of alcohol. Consequently, there was no danger of migration of parasites from one bird to another.

Menopon incertum Galeoscoptes ■ — Catbird carolinesis This list of species of parasites as related to the hosts upon which they were found is a new one in distribution. Many species (marked N.H. — New Host) here noted were not observed upon these same hosts by other observ- ers. It will be noticed upon comparison with Kellogg's list that generally they are the same genera of birds but a different species. Docophorus communis is a widely distributed species. Besides those hosts indicated by Kellogg and others. I have found it on Cyanocitta crista ta. Nirmus vulgatus is recorded for Morula migratoria and for a number of species of western Pipilo. I have found it in addition on Passer domestlcus and Pipilo erythropthalmus. Colpdccphaluni chrysophaeum, I found on Toxostoma rufum and Quiscalus (luiscalns, whorcas Kellogg observed it upon Melosphiza fascinata samuelis in (California. Physostomum difEusum. I found on Poecetes grammineus and Kellogg noted it on Zonotrichia coro- nata, a related species. Lastly, Menopon incertum was found on Galeos- coptes carolinensis and other observers found it on the Gold Finch and the Russet-backed Thrush (Spinus tristis and Turdus ustnlatus). This distribution indicates clearly that even though a certain species of louse is observed on a host different than that of another observer, it is a host very closely related. Sometimes there are exceptions and for these Kellog has* no other explanation than that of migration from one bird to another when in close quarters, in roosting on trees during migration of the birds, or huddling together of certain water birds on floating weeds and wreckage at sea. One interesting fact remains, that closely I'elated genera of parasites infest closely related genera of hosts. BIBLIOaiiAPHY. Kellogg, ^'erncni L. — New Mallophaga I — Proc.

Tlic ;i ll.uht for six hours, it was found that I lie melanophores were strongly contracted. The effect being opposite to that of light.

On injectuig X)C, cc of adrenin. 1 :1()0() into frogs kept six hours in the light, the pigment was found to be fiUly expanded after 7-Lj minutes exposure. Then other frogs were kept in the dark six hours and injected with same amount of adrenin and the pigment was also expanded. Control frogs in the dark showed the pigment contracted. So the conclu- sion was reached that the adrenin has the same effect as light. The retinal pigment was sensitive in sctluticns from 1 :1(M)0 to 1:1000000 and remained for three to four hours. The effect on the dermal melanophores is Just the oiijiosite to that on the retinal pigment. This is new to science. In the above experiments, the frogs were decapitated, eyes removed, hardened in Perenye's fluid, imbedded, sectioned, and mounted unstained. 143 THE EFFECT OF ( 'E.NTUIFrciAL F(»K('E (»\ I'LAXTS.

Since the time of Knijibt some otlu>r investisjiitors liave investigated the action of centrifugal force on various i)lanls and especially some of the stmlics have been made on s(>edlings. These ai'c generally of such size or can be so selecte(l, as to lend tliemselves advantageously to exi)erimentation of this s(U-t. Among the investigators who followed Knight in this Held of study may be mentioned :Miiller- who made a study of tlie growth processes of roots when acted on by centrifugal force. As in the case of Knight the anH)unt of centrifugal force which Midler employed in his experiments also was small. Ten years later the sul)ject was again prominently investigated in a sinular way by EUing-' who also used only a small amount of cen- trifugal force. The amount of such force which Elfing used varied from U9-50g. which was slightly greater, however, than that employed by the above mentioned investigators. The original paixn- of Elfing I have not seen. An extract of its contents has been given by F. Schwartz in the liotanische Zeitung Bd. 39, ISSl, P. 17() above referred to. At the sanje time that the paper of Elfing appeared a similar piece of investigation had been completed independently by F. Schwartz.^ This paper by Schwartz also apiH'ared in ISSl from Pfeffer's laboratm-y in Tubingen. Schwartz worked wdth a specially constructed form of centrifugal machine which, however, did not nse the ordinary form of revolving drum. Instead it wa.s so constructed that it carried at right angles to the revolving main shaft, a second shaft that carried a number of boxes which contained the speci- meps to be investigated. These seedlings were grown in sawdust which, however, is objectionable in some respects to use in a machine of this type during experimentation. The boxes just referred to were so placed on the second shaft as to balance one another during centrifuging. Various other contrivances in connection with this machine were used iin simply because it was not of sulliciont intensity. In all the experiments which I performed the contents of all the cells was thrown to the centrifugal end of the cell. It returned to its normal postion in the various cells whether they were large or small after two to three days. Even after the contents had returned to its normal position, as indicated above, a much longer time was still necessary to allow the complete shock of the centrif- ugal force to disappear. This varied according to the plant and the intens- ity of the centrifugal force. w TllK KFFKCT OF AFRATlON O.N PLANTS.

Leaf aiTaiiiloiueiit in plants lias always hvvu a \h,\u\ ..1' li.lcrest aiA has liccu llu' suhjiM't of nim-h study. Sonu! plants have a very open or loose ari-aii.i;(>niont of tlioir loaves as when tlioy are separated by considerable distances on the stem as in some alternate or opposite leaves. The number or arrangement becomes greater and denser in other plants until their leaves form rosettes or culsters as in the common HonsclcfU. Or again as in the cones of the genus Pinus \vhos(> scalc-liUr loaves often form conical-like cylinders of closely set divisions. Vari.ms theories were b.ng ago advanced to (>xplain the arrangement (d' leace^ on the stem and especially by Ce.salpino and r.onnet that the arrangement on the stem is in keeping with dehnite "geometrical rules". Also many others among them A. F. Schimi)er had formulated a theory on the subject. An excellent summary of many of the facts on this subject has been collected by Sachs. But the effort of the plant is to arrange the leaves on its stem in such a manner that they will have the best exposure to the light. Also the questi(m of structural phy- sical factors in the plant itself enter into the placing of leaves on the stem. The arrangement which a given species shows is followed by all individuals of that species although, as will be seen later, this may be departed from to a certain extent. This difference I found rather markedly shown in the spiral arrangement of the leaves of Specularia perfoliata. Gray* de- scribes Specularia perfoliata as follows: "Somewhat hairy. 1-9. dm. high, leaves roundish or ovate, clasping by the heart-shaped base, toothed, flow- ers sessile, solitary or 2-3 together in the axils, only the upper or later ones having a conspicuous and expanding corolla, capsule ellipsoid, short, straight, opening rather below the middle: seeds lenticular". Nothing is said by Gray, Britton. or Wood about the rather marked and regular arrangement of the leaves on the stem of this plant in spirals. This arrangement together with the form of the leaves is a sti-iking characteristic of Specularia perfoliata. and reminds one but to a much less degree of the unusually ".si>irally twisted raceme" of flowers of Spiranthes gnicilis. AVhen making a trip into Brown County. Indiana, during the summer of T.C'O. I noticed by the roadside about one mile from Belmont, near the studio of the artist, Dr. T. C. Steele, a large number of specimens of Specularia l)erfoliata. Most of these plants were of normal size and appearance. Their leaves were arranged on the stem in the usual way and as to number showed four to a single turn of the stalk which is the ordinary number. Als(j ordinarily three circuits of the stem must be made before a leaf will be found that will stand on the stem directly above the first leaf with which the count was begun. In other words the twelfth leaf, counting the one at the starting point, will stand directly over this first one where the spiral was originally started toward the base of the stem. In this arrange- 'Sachs, J. History of Botany 1875 P. 16S. =Sacks J.. History of Botany 1S75 P. 162. "Saclis, .T. History of oBtany 187.">, Chaptor 4, PP. ^.^.^-le. This adds tii'catly to the e\i>eiise. lial)ility to .net out of order, and makes the ai>paratus unduly lariic and heavy. A microtome, as most other types of machines, should not he made heavy simply to remain in one position, hut should only be heavy or suhstantial enoiifih to prevent sprinsinf? or fiettinj; out of allij,'nnient when in use. < »f course this is a point tliat merits due coiisi(lerati(tn in a inicrotonie when such very thin sections are to he out. hut still the present weiglit of most such machines of the microtome type can he greatly reduced without detriment. A simple table clamp is all that is necessary to obviate most of the difficulty of shifting of the position of thu machine. The chief weight is. of course, in the framework of the machine especially in the wheel base, slide pillar and uprights of the microtome I used. This is true of most machines of this typ(>. The weight of these parts could be reduc(>d to one-third or even one-half of what it is without sacrificing any necessary rigidity. The weight of the wheel and frame running on the slide pillar could he much reduced especially by the proper adjustment of the balancing of the weight of the two since they are connected to the same shaft. This same balancing of weight is seen in the adjustment of the pitman rod on the crank of engines and other much more delicate machin- eiy. The difference in weiglits and balancing here refeiTed to in the case of microtomes is so considerable as often to cause considerable inconven- ience and unsteadiness in operating the machine. Part of this adjust- ment, as the machine I used as now arranged, could be partly arranged for by a different length in the threading r or later, a source of annoyance and often 152 Proceedings of Indiana Academy of Science. Fig. 1. M. Fig. 2. Median longitudinal sectional view of tli( 4-- dor-k. Natural Fig. 3. Top view of nrass block, natural size. caused inaccuracies in tlie ttiickness of the sections that were cut. This latter was caused by weakness in the springs, one of which controlled the ratchet of the cogwheel, and frequently on account of this the cogwheel was not turned the specified distance. Sometimes the sections were cut too thin or the block was not set out for cutting at all. At other times a notch in the cogwheel was skipped causing the section to be cut too thick. The above mentioned imperfections of the system of springs for adjusting the thickness of the sections was overcome by the use of a simple contriv- ance which at the same time insured accuracy and uniformity. The micro- tome I used is provided with a brass cogwheel 7.5 cm. in diameter, a cir- cumference of 235.6200 mm. and having on its periphery 100 cogs (A Fig. 1). This cogwheel is attached to a threaded shaft which moves the paraflBn Regulalhuj the Thivkness of Microloiiic i^ections. 153 block out carrying lli(> spccinicii to ilic soctioiiiiif,' knife. The threaded shaft's diameter is r> iiini. and its circuiiirereiico in.TOSO mm. The circum- ference of the wheel is therefore 1". times that of tlic shaft. Since tliere are 100 notches in the circumference of the wheel the shaft turns .in mm. jier notch or 1.^0 n. TJie shaft is threaded with 20 threads to 1 cm. and therefore one thread or revolution or the 100 notches eiiuals ~, mm. or ."iOO u that the .section is moved out. Therefore when the larse cogwheel is turned one notch tlu< parallin block carryin.i; the specimen is moved out so that a section 5 u. thick will be cut. The above mentioned points make it clear that a faulty .spring .system for a machine cuttinjr such thin sections would be serious for even rather thick sections and especially so for very thin ones. My improvement is the use of a brass block (F. Fig. 1 ) attached to post (\ This post was originally in the machine and carries at the top a metal arm D so arranged as to arrest the movement upward of a lever E attached to the brass cogwheel A above referred to. The metal arm E projects :].'> cm. beyond the circumference of the brass cogwheel A and carries a ratchet Ct. which turns A as the siiecimen is raised above the sectioning knife. The brass block 15 attached to C, for regulating the thickness of the microtome sections, is made of solid brass. It is 35 mm. long and 21 mm. wide on the upper side, Fig. 2. In Fig. 2 A is the path of the post C through B ; B is the insert plate. F. the set screw and D the set screw for the brass block B. The block B is 25 mm. high, 23 mm. long and 21 mm. wide at the shoulder where the set screw I), is placed Fig. 2. The part projecting above the set screw D which tightens the block B on the post C is 11 mm. thick, Fig. 2. This part which is just above the set screw I have cut out so as to allow an insert plate i\ Figs. 2 & 3, to be used. This I made from a steel plate which covers the bobbins of a sewing machine and cut th(> brass block as illustrated so that its sides had the same angles as the steel plate and al- lowed the latter to slide true in the channel cut Fig. 2 c. This steel insert plate is in cross section 14.5 mm. at the base. 13 mm. at the top and 21 mm. long, C. Fig. 2 & 3. The illustrations C Fig. 2 & 3 represent the exact size. The block has a hole 12.5 mm. in diameter bored vertically through it at one end of the insert plate. A, Fig. 2 & 3, so that the post C, Fig. 1, can he passed through it. and on which it can be moved up or down to the desired position. In case of wear on the brass lever E a new brass tip can be used. In fact it can he grooved and short new insert plates used there as at C. Fig. 2 & 3 on the lower side of E at the striking point. I made use here of the principle that hard and soft metal surfaces where wear is present should be brought together so that any wear will take place on the soft metal which can be replaced. This principle is used generally in machin- ery. Since the metal arm E strikes the insert plate with a sort of shearing stroke in descending it has a tendency to push the insert out of place. . This I have remedied by putting a set screw B, Figs. 2 & .3. through the insert plate C and into the brass block B. Fig. 2. This is not shown in the photo- graph but is shown in the drawings of the brass block. Fig. 2. Figure 2 is a drawing of the brass block above mentioned which I constructed for this imrpose. It carries on its upper .side, where the lever strikes, the insert plate above described. :Many of the later types of microtomes of the kind here illustrated are even much more complicated. In addition to a com- 154 Proceedings of Indiana Academy of Science. plicated and cumbersome system of expensive adjustments these parts are often housed in by a metal enclosure. All this adds, as above stated, unnec- essarily to the vpeight and size of the machine and especially to the cost. The metal housing, just referred to. (inly partly protects the mechanism from dust or other injury. This would he as well or better affected by a cardboard cylinder or even by a properly made cloth hood such as is used to cover microscopes when not in use and which are left temporarily on a table in the laboratory. A light glass box can easily be made of plates of single strength glass held together at the angles and corners by strong adhesive tape. One of these I have made and used for years with entire satisfaction and whose cost of making was trivial. I marked a graduated scale on the post C to control the number of notches on the wheel A and consequently the arc through which it would be turned and therefore the thickness of the sections that would be cut. For example when the top of the brass block B was placed 52 mm. from the base of the post C the wheel A was turned one notch and a section 5 u was cut. Raising the block B 3.5 mm. more allows a section 2 notches or 10 u thick to be cut. When the block B is raised 4.5 mm. above the second mark on C. just mentioned, a section 3 notches or 15 u is cut. Raising the block B 3 mm. above the third mark just mentioned a section 4 notches or 20 u is cut and so on. As the lever E goes up and down it moves not in a small curve, as might be expected, but in a straight line. When, however, the lever E strikes the arm D on the brass block B, Fig. 1 the lever E is turned the amount desired. This really is equivalent, in principle, to a small arc being formed when the cogwheel O is turned as a result of the small divisions for adjustment on the post C. Each one of the small arcs is very small at the periphery of the cogwheel A. especially when the brass block B is placed 52 mm. from the base of the post C which allows, as stated, a section only 5 u thick to be cut. Due to wear and especially to lost motion, the calculated positions and distances from each other that the adjustment marks on the post C should be placed for cutting the sections of different thicknesses did not quite correspond with those positions found by experiment. The variation, however, was not great and if all lost motion could be eliminated the calculated and experimental data would of course exactly coincide. The marks and figures on the post C are conveniently made with an etching tool or by covering the surface of the post C. with paraffin or better with beeswax and then applying concentrated HNO3. Back of the cogwheel A. Fig. 1, were originally placed two lugs or pro- jections cast in or built in with other parts of the microtome here shown. Fig. 1. These are so placed as to limit the sections, as they could originally be cut, to a total thickness of 50 u. This is a much greater thickness than the majority of microtome sections ai'e ordinarily cut. Occasionally, how- ever, it is desired to cut sections thicker than this and the arrangement just referred to above of thickness limitation of the sections is a decided inconvenience. This difficulty may be solved by removing the lugs or pro- jections above mentioned. This would then allow a sweep of the arm E through a much greater arc and would allow sections of very much greater thickness to be cut. A corresponding long graduated arc can then be at- tached by a shouldered center to the post C which would control by means of a movable arm the movements of the metal arm E to any desired de- gree or extent and therefore still cut very thin or very thick sections. sTriMKs (»\ i'()i,i,i;\. 111.

Siii<-(> tli(> ;ii)ii(':ir:iii((> of my second contribution on tlio study of pollen I li.-nc continued my invest iir.-i lion on this subject and luivo added a considcr- .•il>le nundier of plants to those already studied in ways mentioned in my previous paiiei-s. As the work has pro-ressed certain new methods have > n.i,'i,'ested themselves as exitedient or in many cases as necessary for the inoiier advance of the work. One former method of allowing pollen to be l)l;iced for siermination in the desired solution between a slide and cover- iiiass is. while often sivluK results, unfair since certain life processes can not nornnilly be carried out under these conditions. Tlie use of an ordinary ulass riuR cell cemented to a slide and havini; the pollen for investigation in a hanging drop also served in many cases l.nt :iliowe(l of no regulation of temperature by an exchange of aii- in the ways desired. A common gas chamber served the purpose better and (.bviated the ditliculty just men- tioned and also allowed of certain otlu-r f(n-ms nf experimentation, not i:ossible with the glass ring cell, that 1 hope to investigate later on. In this last type of culture cell, as here used, it was necessary to use wet niter pai)er in the cell or a small (piantity of water to prevent the specimen from drying up. All the culture cells mentioned thus far had the disad- vantage of allowing only one experiment or culture to be so arranged at ( ne time. To offset this the glass ring sell was used in large numbers but individual cultures made in this fashion reipiire a great deal of extra work and are not conducive either to convenience or accuracy. In some cases at lirst when an extra large number of cultures were to be made I suppli- niented the glass culture ring apparatus by cells made of filter paper and kept moist in damp air under a bell jar. These latter, how(>ver, were much less satisfactory for various evident reasons. Since my second contribution on this subject I have increased the number of plants whose pollen I have studied from 48."i to 540. In the case of all of these 540 plants I have tried to grow the pollen in the following solutions : distilled water and cane sugar of 1%, 59^. 107^;. 15%. 20%, 30%, 40%, 'tO'/c and 60%. A great many, of course, did not grow but many did. The pollen of all of these 540 plants were experimented with in this way and given a trial even though, as is well known, some few of them have not yielded results in this way. Of these 540 phanerogams only the pollen of live i»roduced more than one tube on germination. This is very different from some pollen which produces many tubes on germination as in the case of .Malva crispa. Of all the 540 plants I found only one whose pollen tube branched. That was the pollen of Caladium bicolor one of whose pollen tubes branched three times and two of whose pollen tubes branched twice. The record of this plant is as follows, viz : In distilled water ten pollen grains in one hundred germinated. In the cane sugar solutions 21 germin- ated in the 1% ; 4 in 5% : 0 in lO'/r : 3 in 157r : 27 in 20^/r : 15 in 30% ; 3 in 40% ; 0 in 50%. and 0 in (>0%. The pollen in this exi)erimeut was all of the same age and grown under exactly the same conditions. The first jioint of interest, therefore, is that in 10% none grew while just above and 156 Proceedings of luO'iuiia Academy of Science. below this strength of the sugar solution the pollen grew. The second point of interest is that the branching of the pollen tube which this plant showed occurred only in the 30% of cane sugar and as above noted. It will be seen that in 40% cane sugar the germination dropped ofe greatly as only 3 grains of pollen grew. It has been known for a long time that the pollen tube sometimes branches as it descends through the stigma of some plants. The germination of the pollen of this plant was rather slow as it required one-half an hour to begin. Its pollen lived in the ungerminated condition for eight days and it grew best in a 20% solution of the cane sugar. Most of the pollen experimented with in the cultures used in this investigation was from plants gathered in Monroe County, Indiana. Some of the plants were obtained from widely separated localities and where- ever and whenever an opportunity presented itself. Some came, for ex- ample, from Texas, some from INIissouri, and others from Colorado which I gathered on Pike's Peak and vicinity. Twelve plants from Pike's Peak that I tested especially as regards their longevity, lived only ten days in the longest case. Some of these I did not expect would germinate under any conditions, whether their pollen was young or old, and this was fully verified by experiment. However, these plants were in every case also subjected to the usual investigation in order to leave no doubt on the ques- tion. Still others of the plants came from Dearborn County and from Clark County, Indiana. All of the experiments in this paper were carried out, as above stated, in pure distilled water and in the different strengths of cane sugar mentioned. The distilled water and cane sugar were as pure as possible. No experiments were performed or attention given to the question of additional siibstances, such as gelatine, added to these solu- tions. Considerable work also has been done in some phases of this field. It constitutes, however, a problem in itself and merits much more extended investigation than it has yet received.

A more careful study has led to the conclusion that they are more properly referred to T. Oniitliogali. This species has been commonly considered identical with I'. Colcliici but is treated separately by Schellenberg in his excellent monograph of the smuts of Switzerland (Beitriige Krypt. Schweiz -3^:139. 1911).

This collection was made in a dried up glough on the terrestial form of the host. It consists for the most part of the conidial form which occurs equally as abundant on the upper surface of the leaf as on the lower, a con- dition not found on other host siiecies. This is doubtless correlated with the fact that the stomata are abundant on the upper surface of the leaves in the terrestial form.

The following report on the rusts of Indiana is suplcnientary to lists l)ul)lished in the Proceedings of the Indiana Academy of Science for 1915 and for 1917.= The present paper is divided into two parts. In the first part an attempt has hoon made to list all the unrecorded hosts for si">ecies included in the 101.") and 1D17 lists. Most of these host records represent new collections. Some of them, however, are corrections to previous determinations, while others represent collections which were overlooked. In a few cases the (Ictormination of the rust has heen found to he incorrect and corrections (pf sucli have also heen made. No attempt has heen made to list the large inuubcr of collections which have been made on hosts already recorded. The number preceding the species name in this paper is the same used lor that species in previous lists. The nomenclature, however, is not the same. In the 19in list the nomenclature used was that proposed by Dr. J. ('. Arthur and based largely on life histories. In the present list the more familiar generic names Pucclnia and Uromyces are retained. In each case, however, the name used in the 191") list is given as a synonym. In the second part, twelve rust species which are new to the flora of Indiana are recorded. These are numbered consecutively with the two previous lists and bring the total number of species for the state to 167 (Xos. :Ui and 70 are to be dropped so that the real total Is 1G.5). In order that the series may be more useful to collectors a complete host index has been prepared by Miss Evelyn Allison and is appended. Acknowledgment is gratefully made to all those who have contributed siH'cimens. The name of the collector is given for each collection except where made by the writer. Special acknowledgment is due Mr. C. C. Deam wild through his keen observations and knowledge of the state flora has made many notable additions. Mrs. Agnes Chase. Mr. K. K. Mackenzie .ind ;\Ir. Paul ('. Standley have determined many of the hosts. All of the collections recorded are represented in the Arthur lierbarium at the Pui'due University Agricultural Experiment Station.

The specimen on which the record for Puccinia Ranunculi Seym, was ba.sed (c. f. Underwood. Proc. Ind. Acad. Sci. 1893:55) has recently been examined and the rust proves to be PolijtheUs fusca (Pers. ) Arth. (c. f. no. 135) and the host Anemone quinquefolia L. The error in determination has l»oen i)erpetnated throujjh all the previous lists of Indiana rusts. There is some discicpancy in the records but there seems to have been but one collection involved, which was made in ]MontKoinory County in June, 1893, by E. W. Olive ^nd A. A. Hughart, or it was collected by Hughart and communicated to Underwood by Olive. Puccinia Ranunculi Seym, is therefore to be stricken from the Indiana flora. It is a very rare rust known in North America only from the type collection, which is now interpreted as on Ranunculus septentionalis Poir. made by Br. J. C.

The rust on Potentilla canadensis L. so common throughout the state and recorded as Knehneola ohtusa (Strauss) Arth. in the 1915 list has been restudied and its affinities determined to be with Phragmidium rather than Kuehneola. It is a brachy-Phragmidium and on this account, Dr. Arthur has erected the genus Frommea (Bull. Torrey Club 44:503. 1917) to in- clude this and one other species. The name is written Frommea obtusa (Strauss) Arth. {Phraomidium TormentiUae Fckl.). European authors in general do not consider the American species identical with the European. Those who accept this view should write the name of the American species Phragmidium triarticulatum (B. & C.) Farl. (Arcgma triarticulatum B. & 0.). Urcdinalcs oj Indiana. III. ]~:\ n:'..

It was first col- 174 Proceedings of Jtidiana Academy of ficience. lected May 16, 1S99. and has been repeatedly collected there, especially from 1902 to 1908. by different people. About 12 different collections are depos- ited in the Arthur herbarium from this locality. During the past 12 years, howevier, no collections haAe been made, though it has been repeatedly searched for, and we have feared that the species was extinct in this locality. It was. therefore, with considerable interest that the writer made collections of this rust on July .") and Sept. 2, 1920 in a small swamp about one-half mile northeast of Dayton in Tippecanoe Co. 143.

The specimens listed above were in part included in the 191i') list under No. 101, Oymnoconia mtermtialis (Schlecht. ) Lagerh. Recent studies by Kimkel have shown that there are two forms of the orange rust of black- berries and raspberries, one a Caeoma with an Endophyllnm-like life his- tory and the other an opsis-Puccinla-like form. The former has been sep- arated by Dr. Arthur (1. c.) as a new genus, Kunkelia. For the sake of emphasis this name is used alxive, though it should be recognized that there is considerable difference of opinion as to the relationship of the two forms, esix^cially in view of very recent investigations by Kunkel (Jour. Agr. Res. 19:501-512. 1920) and Clinton (Conn. Agr. Exp. Sta. Bull. 222: 469-473. 1920). The writer is inclined to believe that we have here a rust whicli is in an advanced stage of an evolutionary transition from a long to a short cycled form, the transition taking place in the direction of the aecium and the long cycled form surviving in certain regions and on certain hosts. 160.

This, the leaf rust of barley, was collected for the lirst lime in Indiana as indicated above. A number of other collections in various counties of the state have since been made, indicating that the rust was not uncommon in 1918. but was not present in severe form. Tsn.illy the infection was very slight and required careful search to find it. Tranzschel has shown that this rust in Russia has its aecia on Oniitho- galum umhellattim and O. narhoncnse (Myc.

Kern (Mycologia 11:134-147. 1919) has recently pointed out the distinction between the two species. The aecidium of this species is unknown. 163. PucciNiA Pimpinellae (Strauss) Link, in Willd. Sp.

The writer has used a simple, type of plant press during the past ten years whicli has proven very practical and satisfactory for general lab- oi'atory purposes. On accomit of the simplicity of construction and the low Initial cost of this apparatus it has seemed desirable to furnish a description of it with specifications and illusti-ati(ms for the benefit of those who may not have solved the problem of drying plants to their satis- faction. The first press of the sort to be described was constructed in 1911 for use in the laboratories of the Department of Botany and Plant Pathology at the Oregon Agricultural College. From one to four of them have been in constant use there since that time both for general laboratory pur- poses and for use in connection with classes in taxonomic botany. The writer has also used, since 1915, presses of similar construction in the P.otanical Department of the Purdue Agricultural Experiment Station. A number of persons from other laboratories who have seen these presses in use at one or the other of these institutions have adopted a similar type. The apparatus consists essentially of a box with rack on which the plant press rests, provided below with a source of heat (Fig. 1). The box is 15 by 18^^ inches, inside measurement, and is open at top and bottom. It may be made square 18i/l> by IS^A inches if desired. The sides are made of one inch boards, ten inches wide and fastened together with screws. A rack on which the press rests (Fig. 2) is provided and placed three inches from the top of the box. This is made of material one inch square and is fastened all the way around the inside of the box. One or two cross pieces are added as illustrated, though are perhaps unnecessary. Yellow poplar lumber is foimd to be very satisfactory as it is not so liable to warp as some other kinds. Heat may be conveniently supplied by two or three carbon filament electric light bulbs, the sockets for which are fastened about three inches from the bottom. Two sixteen candle power lights are sutticient for ordin- ary purposes, depending somewhat upon the succulence of the plants to be dried. It is well, however, to provide three sockets placed in such a way as to give the most imiform disribution of heat. The writer has also used, with entire satisfaction, special heating units of low resistance so 'Contribution from the Department of Botany, Purdue University Agricultural ExiKTiiiient Station.

Any convenient method of supplying lieut b;^- electric current may be used. It is important, however, that only a small amount of heat be supplied. It is only necessary that a draft of warm air passes through the corrugated boards of tlie press. Three one inch auger holes two inches from the bottom are provided on each side of the box to allow for intalce of air. The sides of tlie press are made of one inch boards 12% by 18 inches. It is best to fasten a piece one and one-half inches wide crosswise at either end to prevent warping. This should be tongued and grooved and glued. Canvas straps with friction buckles are permanently fastened to the boards at either end as shown in the illustration. These should be of such length as to allow for the maximum expansion which the width of the box permits with sutficient additional length to conveniently allow for drawing the press tight. Double faced corrugated straw boards cut so Fig. 1.— The Plant Press in Use. Double faced corrugated card boards, cut so that the corrugations extend the short way, are used between the driers. Heat is supplied by two or three carbon filament electric light bulbs, or by special heating units constructed to fit an ordinary electric light socket. Any thickness of press, within the limits of the width of the box, can be used. Boards one and one-half or three inches wide are provided to fill in the space at the sides of the press on the rack when only a small amount of material is to be dried. Ventilation is provided by six one inch auger holes placed three on each side of the box, two inches from the bottom. Photo by M. W. Gardner. A Coiirciiiciil /jihoriilori/ I'hnil frcstft. is: lliiif (lie corrugations run the short way arc used between (lie dryers. When sueculent material is to be dried ir is iicrliaps preferable to use one cor rufiated board between each pair of dryers. For the ordinary type <»f ma- terial two plant sheets with three dryers between each pair of corrugated boards is found entirely satisfactory. fJrasses and other similar plants will be found to dry .satisfactorily when three si)eeiiiiens and four dryers are phiced between the corrugated boards. Folded sheets of newspaper are found to be entirely satisfactor.\ fnv use as plant sheets, though tlie si)eeial sheets for sale by all dealers in hcrliarium supplies are preferred by many collectors. When plants are being dried for illustrative purposes a layer of sheet cotton may be u.sed to advantage between the specimen sheets and the dryers. When only a few plants are to be dried and llie press is thin, a floor of loose but closely fitting boards should be laid on each side of the press on the rack so that all the heat will pass through the ccn-rugated boards. For this purpose four boards 38 inches long, two or which are one and a half inches, and two three inches wide should be kept conveniently at hand. .Most material will dry in this press in less than twenty-four hours though very succulent plants will require a longer time. If the press is turned over every few lumis during the early part of the drying period Fig. 2. — Box Raised on Edge to Show Construction. The inside dimensions of the box are IS^^ by 15 inches. The sides are ten inches high, open at the top and bottom. Sockets for electric lights are placed three inches from the buitdni. and the rack on which the press rests is three inches from the top. The press is made from one inch boards, 12^2 I'.v IS inches. Canvas straps with friction buckles are pr(i\ ided at either end as illustrated. Note the loose boards which are used for a floor at sides of press when only a small quantity of material is being dried. Photo by JI. W. Gardner. 186 Proceedings of Uidiaua Academy of Science. the plants will dry In a shorter time. As the plants become dry con- siderable shrinkage occurs and it is desirable to tighten the straps once or twice. Where large quantities of plants are being dried at one time the appa- ratus described may not prove as satisfactory as some other methods in use, though a battery of four or five such presses will be found to be ample for ordinary class work. For the laboratory which has only occasional use for a plant press or for the individual collector it will, we believe, be found quite satisfactory. ISl INDIANA ri,ANT DISKASKS, r.H'O.' Max W.

As in the previous report, the economic point of view is maintained. Weathkk Conditions. The important relation of the weather to crop diseases warrants a brief reiiort based upon the monthly summaries of Mr. J. H. Arminston of the federal weather biu-eau at Indianapolis. The extremely cold, wet weather of April delayed farm operations and retarded crops several weeks. The tirst half of May was also very cold. culminating in frosts the 14th and lath which caused considerable injury to fruit. In some localities seed potatoes rotted in the ground because of the cold wet weather. The latter part of May and all of June and .Inly were in general favorable to crops. June and July were exceptionally cool and rainfall was fairly abundant. Severe hail injury occurred at Vincennes. June 1. at Madison, June 14, and at Kokomo. Berne and Decker the 28rd. At Decker the in- jury to corn, wheat, oats, tomatoes, melons, peaches and apples caused a loss estimated at 150.000 dollars. August was also fairly cool and the whole summer up to the end of August was characterized by the absence of any period of heat and drouth. This type of weather greatly lessened the destructiveness of the Fusarium soil diseases such as cabbiige yellows and favored the preva- lence of such diseases as Septoria leaf-spot of tomato. September was very hot especially during the latter half with less rain- fall than in previous years in central and northern Indiana and dry warm weather continued well into October. This type of weather favored the ripening of fall crops and at the same time was not especially conducive to i)lant diseases. Light frosts occ\u-red October 20 and heavy frosts the end of the month. In general the 1920 season was distinctly dilTerent from its itrede- cossor and the difference in weather is r:ither strikingly retlected in the plant di.sease conditions.

Tlie Mann and Maiden Blush should be added to the list of Fig. 1. Apple blotch. susceptible varieties in the 1919 report. At Mitchell. Prof. Greene noted abundant fruit infection June 10 and petiole lesions were noted at Moores- ville June 11. Unsprayed Northwestern Greenings at Knightstown showed as high as 91 per cent fruit infection and 39 per cent petiole infection and at Mooresville as high as 97 per cent fi'uit infection and 83 per cent petiole infection. Counts made by Burkholder in Clark county showed 97 per cent fruit infection on unsprayed Ben Davis trees. Good control was se- cured with Bordeaux sprays 2. 4 and 6 weeks after petal fall, while sulphur dust, Bordeaux dust and dormant sprays were ineffective. Scab (Fig. 2) caused by Vciifiiria inaequalis was especially severe in tlio southern part of the state but rather light in the northeast quarter of the state where its ravages are usually the worst, according to reports by Burkholder and Cullinan. Burkholder reports very little scab on unsprayed cheek plots in AVliitley county except upon Ben Davis and Fameuse. On the other hand, the same observer reports that scab was more severe in the region between Crawfordsvillo and the Ohio river than in the preceding three seasons. At Mooresville. June 25, scab was noted to be abundant on Indiana I'hnil ni.scdsc.s. iyeen killed by fire-blight and was harboring the black rot fungus. On the other hand this leaf-spot was also present on young, well cared- for trees, .hnie 25 the leaf-spot was noted to be especially bad on the varieties Ben ]>avis and Jonathan. The fruit rot of the blossom-end type as well as the type following blotch, scab and worm injury was very common late in the season. Fire blight due to Bacillus amylovorus was very common on apple trees ni'ar blighted pear trees. Because of the prolonged growing season this year the attacks of fire blight continued well into the summer. July 2 this dis- ease was found rather prevalent on certain varieties in a large orchard near Vincennes. An orchardist at Laurel found that thorough spraying for aphis control was effective against blight and that iinproi>er spraying re- sulted in an increased amoiuit of blight. Sooty blotch and fly speck ( I.cplothi/riion jxniii) were very common on certain varieties. 190 Proceedings of Indiana Academy of Science. ~i Rust (Gymnosporangium juniperi-nirf/inianae) was very severe on the foliage of susceptible varieties. It was noted on Jonathan fruit and foliage in Morgan County Juno 25. Powdery mildew {Podosplwcni Iciirotricha) was found on the Missouri Pippin variety at Ladoga by Dr. P. J. Anderson. The collar rot of the Grimes variety which was recorded last year (as root rot) as prevalent in southern Indiana causes the greatest fatality when the trees are 20 to 25 years old according to Burkholder. He re- ports one case of a 25-year-old orchard near Madison in which 25 per cent of the trees are dead or dyiim. Simc the Grimes is otherwise a very desir- able variety for southern Indiana it has been successfully top worked on other stocks. In the case of all varieties planted on newly cleared land, Burkholder reports that a certain percentage of root rot has occurred. Pig. ?,. Apple .Innathiiii siH.t. Jonathan spot (Fig. P> i was noted at Mooresville. Cullinan reports this trouble as very prevalent this year and found it present on unpicked fruit at Laurel-. Burkholder noted the same thing in Porter County and on King and Black Twig apples still on the trees at Aurora. Bitter pit was rather common on Stark apples at Mooresville and is re- ported by Cullinan as common on Stark, Grimes, and Baldwin apples. Water core was found at Knightstown. Frost injmw occurred in many sections. At Mooresville blossom clusters and whole spurs were killed outright and the set of fruit was severely cu<". Some frost banding also occurri'd. The first leaves were stunted, dark green and wrinkled and many turned yellow and dropped off. Severe hail injury occurred near Decker Jime 23 and the qualify of the crop was greatly lowered. In one orchard the entire crop was rendered unfit for market by the extreme malformation resulting from the hail iiruises.

Downy mildew and Botrytis rot were as usual prevalent in the winter greenhouse crop. A spotting of lettuce apparently of bacterial origin was found rather destructive in a market garden near Indianapolis August 17. Nematode root-knot was found in the infested muck soil near Goshen. Leaf-spot caused by Helminthosporium avenae was noted near Lafayette, May 26. Halo blight caused by Bacterium coronafaGicns was found in Lake county. The smuts are becoming less abiuidant owing to the rather general practice of seed disinfection. Smut caused by Urocystis cepiilae (Fig. 7) was again present in the two onion set fields in Lake county mentioned in last year's report but was J ndidtid I'htiil I >i .sense. fairly well controlled liy the foriuuliu drip on the seed drill.

Taking the state as a whole, leaf curl caused by Ej-0(i.scii.h deformans was by far the most destructive i>each disease and according to Burkholder was much worse than it was during the three previous seasons. Burkholder reports that the disease was severe in Marion. Henry. Shelby. Bartholomew, Brown, Monroe. Putnam. Knox. Daviess. Gibson and Vanderburg counties and especially severe in Morgan and Montgomery counties. Not only was 198 Proceed ill (/s of TrnJidiiii Aeddeiiij/ of Science. cNlrciiu" defoliation caused bnl tlic yoiiiin t'i'uit was dii-octly attacked by tlu> luii,uus.

In the tall r.urkholder noted that hi such orchards the foliage was held about two weeks longer and that only ab(mt one-half the normal twig growth was made. In the Mooresville orchard mentioniMJ above, the varieties Elberta and Big Red were much more severely affected than the Champion and Hale and most of the fruit on the first two varieties had fallen prematurely. The following observations on varietal suscei)tiliility were made by P.urk- liolder: The Crawford was damaged more than any other variety in the state and in Morgan and Montgomery counties there was a total loss of the crop on this variety. The crop on the Elberta variety was cut from three bushels to one peck and the variety Belle of (Jeorgia was fully as susceptible as the Elberta. The Champion variety bore but lialf a crop liecause of this disease. In the same localities the varieties Adudral Dewey, Carman. Smock and Salway bore full crops. Smock and Salway were especially resistant and showed practically no foliage infection and bore so heavily that it was necessary to thin the crop one-half. Burkholder further ob- served that Scalecide was not effective against curl and that a thorough application of the lime sulphur dormant spray was necessary. The dis- ease was destructive in an orchard where the spraying was done with a spray gun on a windy day and unsprayed stri])s were left on the branches. Next to leaf curl, black spot caused by Hncfci-iiini pruni was the most serious peach disease and was much worse than in 1!)19. Burkholder reports that this disease was severe in Vanderburg, Daviess. Orange, Greene and Lawrence counties and worst in Knox and Gibson counties. Black spot was so destructive on the Hale variety in one orchard near Vincennes that the affected fruits were hauled out by the barrel in June. Early in July it was found prevalent on foliage and fruit and to some extent on twigs of the current year's growth. Yellowing of the affected leaves and de- foliation were the result. Severe hail injury to the fruit occurred in the region about Decker and almost every hail wound was infected with this organism so that large blackened cavities occurred on a considerable per- centage of the fruit. Twig invasi(.n through hail wounds was also very gen- eral and Burkholder ob.served twig attack which was severe enough to cause shriveling and premature dropping of the fruit. Burkholder further observed that in orchards containing Itoth the Elbeita and Hale varieties the Hale was much more severely affected by this disease. The same ol).server noted that no control of this disease was obtained in orchards thoroughly sprayed with lime sulphur but that orchards. 11 to 12 years old. which had received several liea\y applications of barnyard manure during their history, showed remarkable resistance to this disease. He further noted that two to three applications of sodium nitrate to orchards of the Hale variety during the current season had no apparent effect upon the disease. hididini I'laiil IHscasr.s. \UU I'.iii-klinld.T ivp.Mls l.inwii nil. ciiiscil by Scl, n,rnii\u\i\ liinwii i-cit worse in llic (ircliniMls .•iITccUmI with tJM" hl;icl< spcil liisc.Msc ;niil .•iccor'din.:; In jiis ohsci-v.-ilions the \:irictics Cluiniiiiun nml C-i i-ni;iii were nmsl M'\crcl\- ;i iTcrtcil.

It seemed to be worse in the central part of the state. Bordeaux sprjiys seemed to control this trouble at I.afa.vette. Fusarium wilt was the most serious disease in the northern half of the state and caiised considerable los.s. F. ('. (laylord reports the disease from I'orter. LaPorte. St. Jose]»h. Elkhart. Kosciusko. DeKalb. Tippecanoe. Hancock. Clarion. Owen and Decatur counties. (Iicu'or.v found wilt also in I, a .ur;! 11 fie and Floyd counties. Undoulitedly much of this trouble was due to the use of infected seed. A field test near \'alparaiso showed a marked re.liiction in yield due to the use of infected seed stock. Tliat soil infesta- tion is responsible for much of the wilt is indicated by the occurrence of the disease in .about e(|ual i)ercentages in test pi. its planted witli seed from widely separated sources and by the aimndjiiice of the disease in a lield planted with seed carefully .s(>lected for freedom from wilt. 200 Proceedings of Indiana Academy of Science. Early blight caused by AUemaria solani was found epidemic in a field ol early potatoes near Indianapolis July 17, and the disease was also noted at Lafayette in the late crop. In October Gregory and Gaylord found early blight prevalent in Floyd and Clark counties in the extreme southern end of the state. Pig. 8. Potato scab. Common seal) (Fig. S) was of general occurrence where imtreated seed was used and soil infestation is not uncommon since scab occurred in some fields planted with treated seed. As a result of the observations of Gaylord and Gregory scab is known to have been present in Lake, Porter, Laporte, St. Joseph, Lagrange. Dekalb, Fulton, Cass, Whitley, Carroll, Tippecanoe, Clinton, Madison, Hancock, Marion, Clark and Floyd counties. Black scurf caused by Rhizoctonia solani was of widespread occurrence as a blemish of the tubers. The disease also caused the stunting and death of young plants. Gaylord and Gregory report black scurf from Lake, Porter, St. Joseph. Elkhart, Lagrange, Fulton, Tippecanoe, Madison and Clark counties. In seed disinfection tests in Lake county as high as 67 per cent of the tubers in the check rows showed black scurf. The occur- rence of a small percentage of black scurf on the tubers from disease-free and treated seed indicated that the soil of this field which had not been in potatoes for five years was infested to some extent. Gregory reports cases of black-leg caused by BaGillus phytophthorus in Laporte, Tippecanoe and Hancock counties. Gregory found the non-parasitic leaf roll disease in St. Joseph, Noble. Fulton. Hancock, Clark, Floyd and Dekalb counties and reports it rather serious in fields noted in the latter three counties. In one field in Dekalb county he reports a 50 per cent incidence of the disease and a 25 per cent reduction in yield. When potatoes grown in the Wanatah region were planted in the greenhouse a low percentage of typical leaf roll plants resulted. Three typical and extreme cases of the mosaic disease occurrd in an Indiana Plant Diseases. 201 exi>erimeutal field at Lafayelte lUantcd with Indiana .^^lowii IJiiral New Yorker seed. Gregory reports a o7 per coiit loss in yield in a liold of Early Ohio potatoes in Dekalb connty dne to mosaic and a 100 por cent infesta- tion of mosaic in a field of the Bliss Triiunpli variety in Floyd county. The potato situation in the vicinity of Hammond presents a serious problem. In past years hii,'h yields wei-e olitaiiied hut now 40 to GO bushels per acre is representative. The plants are distinctly stunted, the leaves curled and wrinkled and the yield reduced to one or two small tubers. Imported seed, especially from the Wanatah region, is considered far more desirable than home .grown seed. Typical mosaic symptoms are not present but it is suspected that the trouble is due to this disease. Considerable difficulty was experienced this year as a result of rotting of the seed pieces in the soil before the si)routs were up. This cau.sed the occurrence of many blank spaces in the fields. Fire blight caused by Bacillus omylovonis was reported from several ocalities. Black-root was noted in cold frames near Indianapolis June 4. Duwnj mildew {Peronospora parasitica) and white rust (Cystop'm camUMs) were found on plants going to seed July 17. Marked hypertrophy of the floral parts was caused and lesions caused by both fungi wore present on the seed pods. KASPBERBY. Anthracnose caused by PlectoiUsceUa veneta is undoubtedly the limiting factor in raspberry culture in many sections of the state and was especially severe this year. Burkholder reports the disease present in the following counties : Lake, Laporte. Lagrange, Steuben. Cass. Miami, Wabash, Foun- tain, Bartholomew. Greene. Knox. Vanderburg, Warrick. Lawrence. Orange, Washington. Floyd and Jefferson. Specimens were received from Whitley and Madison counties and it was also found in Morgan and Marshall coun- ties. The coalescence of old lesions of the previous year a1)out the bases of the bearing canes produces a girdling effect which causes the leaves to be stunted and yellowish and the fruit to ripen prematurely. Affected canes often die before any fruit is matured. Anthracnose lesions were noted on newly planted scions and the disease is undoubtedly introduced into new plantings with diseased cuttings. Leaf-spot due to ficptoria rubi was found in Lake county. KIIUBAKB. Leaf-spot due to Ascochyta rhci was prc^sent in practically all plantings examined. 202 Prorccdiiujs oj Indiana Acadoni/ of Science.

Six si)ecinu'ns of a head snnit ( I'stilago sp. ) were found by Jackson in one held in Porter county. Bacterial blight caused by Bacterium fjlycinctdii was prevalent in holds near Lafayette. Leaf infection was very heavy but i)od infection was not as abundant. An unmistakable mosaic disease occurred on a small percentage of the plants in one field. The leaves showed typical mosaic symptoms, the pods were fewer and smaller, and very few seeds were produced. In fact mosaic plants were prac-tically a total loss so far as seed production was concerned. There were several rows of garden beans along one side of this field which were severely atfected with mosaic and it is possible, of course, that the disease may have crossed over to the soybeans from the garden beans. The non-parasitic yellows or blight which is so severe in the truck region near Norfolk. Va.. was found near (Jo-licn in Octobci-.

It was also noted in plant beds in Indiana by H. D. Brown. Its attack on the foliuKe of plants in the field is not noticeably destructive but serves as a source of fruit infection which probably takes place through wounds made by inserts. The Ijlack, scabby fruit lesions are very objectionable from the caiaier s point of view. The disease is carried over winter with the seed and seed disinfection in corrosive sublimate 1 to .'J.OOO for "> minutes has be.in recommended as a control measure. Fig. rj. Tciiiatu b;i 206 Procvvdhuis o/ hulidnd AauJony of Science. Buckeye rot due to Phi/tophthora tcrrestria was noted in three K^'een- houses near Indianapolis. Only the lower fruits were infected and it is evident that infection was the result of splashing from the soil underneath. ■In one case the rotting fruits were picked off and thrown on the ground thus affording the fungus every oiiportunity to develop and spread to (itli(>r fruits. Strict sanitation should of course bo practiced in attempting to con- trol this disease. ■ Blossom-end rot was vei'y destructive in hotli the greenhouse and fiel. Brown reports a loss of three tons per acre of green fruit actually removeil iK'eause of this disease. This loss is appalling when one considers that the tinal yield was but eighi tons per acre. In the canning crop growth cracks probably occasion move loss ii! the aggregate than all the parasitic diseases combined and this trouble is about equal to blossom-end rot as a source of loss. Not only are growth cracks an objectionable blemish in themselves but most of the fruit rot late in the season in the canning crop both in the field and in the crates is due to the infection of these growth cracks by rot-producing organisms. Growth cracks cause heavier losses to the canner than to '>:he grower since much of the fruit rot occurs after picking, whereas tlie loss due to blossom- end rot falls largely upon the grower. Sunscald was very common owing to the foliage destruction by Septoria leaf-spot and consequent exposui-e of the fruit. Catface was very prevalent in the canning crop and is an objectionable blemish from the canner's stand- point. According to Dr. B. J. Howard of the Federal Bureau of Chemistry, the catface scars are prone to crack and permit rot infection. A peculiar type of non-parasitic wilting of the plants occui-red in the Paoli region and at Lafayette. Affected plants showed the hollow stem condition, the pith having dried out and collapsed even in the very young shoots. At Lafayette the affected plants were near a row of trees along the edge of the field and a similar relation was reported from I'aoli so it is possible that this hollow stem wilt was due to soil drouth produced liy the tree roots. A small, circular, conspicuously white, raised spot with a darker center occurred rather commonly on tomatoes about Lafayette and lndianai)oli--. This has been called "white spot" or "bird's-eye spot"' and is often associ- ated with bacterial spot. Trobably it is due to an insect injury. A Sclerotinia stem rot was found on a few greenhouse plants following wounds and wilt infection. Wind scalding of the leaves was noted at Hammond July I'T. ILiil injury was conspicuous on fruits and stems in the Indianapolis region July 17. From the standpoint of disease introduction the importation of tomato plants grown in the south for the Indiana canning crop is distinctly dangerous. Evidence of the introduction of Fusarium wilt into fields with southern plants Wiis secured. Wholesale nematode infestation of the roots (if the seedlings was found in shipments from several points in the south.

Loose smut of wheat was not as prevalent as in 1!)19. While- the average loss was about 2 per cent, in certain fields as high as 25 per cent of loose smut was found. Pipal reports that in 400 demonstration fields a practically perfect control was obtained by the hot water treatment while an average of 5.1 per cent of smut occurred in the check fields. The central treating plant control method is meeting with marked success. Summary.

While they are not all new to Indiana they are new to the siiecies in the herl)arinm of Indiana University. The object here is not merely to maln published as new si)ecies. These merely needed redescriptions. It is I he belief of the author that a more critical study of material gathered in (luantity and in various conditions of development, will go far to discourage new species making, as well as to bring about the reduction of the number (if tho.se already listed. The discovery of new hosts is especially to be desired as the form of the fungus may vary considerably with the host. The neglect of this careful study in the past has been conducive to the mak- ing of new species. While many new species exist, and while we have a number for future publication, we have come to believe that we can render a greater service to botanical science by extending descriptions already published. Under those listed, no attempt has been made to give complete descrip- tions, but to note the variation from the original descriptions and to ex- tend those descriptions.

Also on inside and outside of loosened bark in the .same region. 3073. Many varieties of this species have been described, based for the most part upon spore size and shape. The foi'm as it appears here, has a remarkably small spore as compared with other forms heretofore noted. So noticeable is this difCerence that a varietal distinction becomes neces- sary. The foUowini; descrii)tion as differing from the species type is here recorded : Pycnidia 150 to HOO microns (Usually 235 to 325.), varying greatly in size and shape; spines 125 to 300 by 5 to 7^^, opaque, especially dark near the base, pointing outward ; spores 5 to 8 by 1 to 2, hyaline. Melanconiales. Cylindrosporium Scrophulariae Sacc. & Ell. On living leaves of Scutel- laria canescens, Griffey Creek. July 7, 1920. O'Neal. 3790. Differs some- what from the description as follows : the broad margin around the spots, is dark purple. Spores are septate and one end often broader. The three guttulae not noticeable. Acervuli about 50 microns in diameter. Habit on the leaves is much like Septoria Scrophulariae. Cylindrosporium Toxicodendri E. & E. On Uhus Toxicodendron, 1911. C. E. Sutton. 3528.

On Betula nigra. Campus, June 31. 1920. These leaves were taken from young trees which had been shipped from Tennessee. Though differing much from the orginal descrip- tion, there seems to bo no doubt of the species being the same as described from Pennsylvania. (See Am. Xat. 1882, p. 1.002.) In our specimens, the acervuli are almost wholly hypophyllous and are variable in size, sometimes quite large and rupturing irregularly. The most striking thing about this si)ecies is the abundance of pointed .spores. They are described as being obovate : however, they also have the lower end tapering to a point. 3774.

Live specimens from the localities mentioned were sent to him and have been cultivated by him in his garden ever since. Among the many species of Iris he has under cultivation are Iris foliosa, Iris versicolor and Iris hexagona. When the three species are grown side by side it is easy to .see that all are quite distinct. It is believed that all references to Iris hexagona in Indiana should be referred to Iris foliosa.

Probably one of the largest collections of mos.ses in the state that has not previously been reported is that belonging to Mr. C C. Deam. Mr. Beam's collection includes specimens from nearly every part of the state. The writer has had the privilege of examining and identifying this collection during the past year.* Another large and excellently prepared and pre- served collection is that owned by Pr;;fessor .T. P. Xaylor of DePauw Uni- versity. Although a physicist. Professor Xaylor has been an enthusiastic collector and student of mosses for many years and has built up a large coliecticm mainly from Putnam County. Miss liUcy Allen, a former student at DePauw. made a small collection from Putnam County which is depos- itee! in the DePauw University herbarium. In addition to these three un- repttrted collections all the species reported in puK- •r.^tions on Indiana mosses known to the writer have been included in i. • list which includes one hundred and seventy-four species, thirty-two of which are being re- ported from Indiana for the first time, it is believed. Under each species is given a list of the counties where it has been found together with the collector's name in parenthesis.

I>niiug the next summer, lOlS. two other simihir ]>lants were diseovered by my mother and transferred to the yard by my father. These three plants and some seedlings from the first of the three are now growing there. I have not seen them during the growing season since 1917": but as tliere seems to be no prospect of my being in a position to investigate their lieliavior soon, it appears to l)e worth while at this time to note their occun'eiic(\ with such notes as the very imperfect observations warrant. The first plant was disc(»vered along the village street about a hundred yards north of the Methodist church in the village of r.looming Grove, Franklin County. Indiana. The distinguishing feature of the plant was the peculiar irregularity of most of the leaf margins, with an accompanying narrowing of the leaves. Many leaves consisted of but little more than the midrib. They had much the appearance of having been partially eaten by chickens, and it was only a careful examination that showed another cause to be responsible. The plant contained a few fruits and it seemed desirable to save seed and determine whether or not the progeny would show the same character, but before the seed were ripe tlie plant was cut off by some workman engaged in mowing weeds. However, one stem with the fruits. was recovered and placed in water. By this means a number of viable seeds was secured. The other stems were recovered for a herbarium specimen, and the plant itself was transplanted to the back yard. In 1918 the peculiar leaf char.icteristic was largely absent. At best it was represented by no more than a slight narrowing, since my mother wrote me that I must liave obtained the wrong plant the summer before, as the leaves were normal. Furthermore, as noted above, she found two more abnormal plants. These were transplanted the same season near the first one. All three of these plants have had the abnormal leaves during the seasons of 1919 and 1920. The first one also produced seed in 1920. Figs. 1 and 2 show the first plant as it appeared in the summer of 1919. Fig. P. shows Nos. 2 and ?> as they appeared at the same time. Figs. 4-0 show tracings of some of the leaves of No. 1. made from the herbarium spe- cimen already mentioned. These show clearly the extreme narrowing of many of the leaves and the irregularities of the margins. On April 18, 1918. one hundred four of the immature- seeds .secured the autumn before were planted in a shallow box. A number of seedlings were secured from them and set out a short distance from the mother plant. Of these seedlings about a dozen are still living. None of them shows the leaf character so evident in the parent. The leaves may possibly show a n am iiulebted to mv mothor. ^rrs. A. C.

I Ciiriniis \'veral scores of feet. About one-half mile from the Madison and Hanover road across the mouth of the valley, there is such an erosion area on the slope facing west. Near the south end of this exposure a large mass of the original rock extends out into the vaUey. as may be seen by referring to the figure. The formation into which the stream is cutting at this point is that of the Lorraine shales of the Ordovician. At this horizon the Lorraine is com- ixised of alternating layers of limestone from one to three inches in thickness and comparatively soft blue shale comprising at least 75 per cent of the whole. At the point "A" in the figure, the stream at every flood stage imder- cuts (he steep slope and removes all debris consisting of broken lime stone and shale resulting from the weathering of the exposure. The projection at "B" is composed of the same material as that at "A", and is from its position especially exposed to the action of the stream at flood stage and thruout its course in the two mile gorge the stream gradient is high. "Why has this projection "B" been able to endure while a similar material both upstream and down has been carried away? In the judgment of tlic writer, it is due to the fact that a spring emerges from the hillside above, the waters of which flow over the projecting rocks at "B", and not only pre- vents freezing, but keeps them uniformly at the same temperature and moisture. The part '"B" which stands out some twelve or fourteen feet be- yond the part "A" and at least six feet beyond the part "C which is com- pletely protected from the force of the flood waters by the projection, is kept well covered by the spring waters at all times. The difl:erence in the rate of valley widening here which is quite marked, is probably due to two, if not three processes. First and foremost is frost action. The alternate freezing and thawing which occurs many times during the winter. loosens annually large quantities of material from the steep sloi>e at "A" which is entirely unprotected by vegetation. The Spring floods i)eriodically remove this. Some material of this sort, however, is loosened and accumu- lated during the summer and autumn. Hence another cause of weathering must be sought, that does not take place at "B". Alternate expansion and contraction due to change in temperature is responsible for part of this work, but in the writers judgment, alternate wetting and drying, which takes place many times during the summer, may be equally as efficacious. At two other points in Jefferson Coimty, a similar protective influence of the waters of springs has been noticed. In these cases the formations protected were resistant Devonian limestones, and the mass of the pro- jecting area was not nearly so great as in the case of the less resistant 248 Proceedings of Indiana Academy of Science. liorraiiie shales described above. These were sufficiently striliing, however, to indicate that all such weathering agencies us the above, probably have much more to do with the widening of valleys in native rock formations than has been generally conceded. xh '^HhjELik_ Photo shdwing character of materials at a and b.

Definition of (Stream P i ra r i/. -i^trvam ])iriicy is not ati uncommon phase of stream ndjiistment dnrins Ihc dovcloidiiont of tlie erosion cycle. Stream piracy consists of the diversion of n jtorllon of a stream system usually hj the encroachment of a portion of a more vigorous stream system. Thus the drainage area of the more vigorous stream is enlarged at the expense of the weaker stream. This encroahcment and divei-sioii take place slowly liy stream adjustment during the development of the erosion cycle. Stream piracy has nothing in common with stream derangement. Streams are fre- ((uently thrown out of their normal courses by such proces.>-es as glaciation vtdcanism, deposition of sand by the wind, etc.. but such stream derange- ment is not considered as a phase of stream adjustment and does not come under the term stream piracy. Stream piracy and stream derange nicnt are very different physiographic processes. Types of ^trc(i)n Pinicii. — lii-oadly speaking there are three types of stream piracy which may accompany stream adjustment. The most com- mon, perhaps, is the headward erosion type. A condition favoring the devel- opment of this type is the cuesta where vigoi'ous streams flow down the steep scarp. Such streams are frequently able to etch their way by headward erosion through the frontal scarp of the cuesta and divert the head-waters of more sluggish streams upon the back-slope. Examples of the headward erosion type have been described by Gilbert. Davis, Darton,.and others. Probably the most famous examples of the headward erosion type .-ire Kaaterskill and Plaaterskill creeks on the frontal scarp of the fatskill .Mountains. Here these streams have undercut the headwaters of Schoharie (^reek on the back-slope of the cuesta. A notable case of this kind in south- ern Indiana has recently been described by the writer.* Muddy Fork of Silver Creek of Clark and AVashington counties lias taken some 35 square miles of the drainage basin of one of the forks of Blue River. In this case the pirate stream had its beginning on the steep slope of the Knobstone escarpment. This form of headward erosion piracy usually gives rise to a barbed drainage pattern. Another form of headward ero.sion piracy is common in such mountains as the Appalachians, where not doubt the trellis drainage patterns so prevalent have been brought about by stream adjust- ment in which headward erosion piracy has played the chief role. The ca.se of the Shenandoah liiver and Beaverdam Creek near Snickers Gap in the Harpex's Ferry locality as described by Willis is a classical example of this form of headward erosion stream piracy. A second type of stream i)iracy may be called the subterranean tyix?. This type is fairly c(tmmon in limestone regions where subterranean drain- age exists. A favorable condition is considerable relief of the limestone i"Some special Physiographic Features of the Knobstone Cuesta region of southern Indiana — An Example of E.xplanafor.v Physiography," Proceedings of the Indiana Academy of Science, 1919. 250 Procccdinr/s of Indiana Academy of Science. area. Subterranean piracy is dependent upon differential work of tlie surface streams in tlieir downward cutting. Tliose stream basins or portions of stream basins wliich are relatively high above neighboring stream basins in limestone regions are subject to diversion by subterranean piracy. The most notable case yet described is that described by Beede in his paper on the "Cycle of Subterranean Drainage, as Illustrated in the Bloomington, Indiana, Quadrangle." published in the Proceedings of the Indiana Acad- emy of Science, 1910. In this case several s(iuare miles of the upi>er por- OUTLINE MAP OF MONROE AND LAWRENCE COUNTIES INDIANA SHOWINC LOCATION 0F\ DETAIL AAAP OF TH£ CUT-OFF PLANATION PIRACY tion of Indian Creek drainage basin have been diverted by subterranean piracy into the more deeply intrenched streams on either side of the head- waters of Indian Creek. The third type of stream piracy is the type with which the present paper deals. It is commonly found where a larger stream has reached the stage of maturity in an area of considerable relief. By the lateral planation of the mature main stream a nearly parallel minor stream may be literally cut into two streams, each entering the master stream independently. The upijer part of the once continuous stream will enter the main stream at the place where the master stream invaded the valley of the minor stream. The lower part of the minor stream will be left in a valley far too large PIdiKilioii >'^trr(nii /'iidci/. 251 for il.

Since tiiis type of piracy talies place on acc(»unt of lateral planation. usually hy the major more mature stream, it is here proposed that this tyix' of stream piracy Ik' called planation piracy. A Tyiilcdl Cane of Planation stream Piraci/. Location and Gco(/rai)liy.— The area which affords a typical example of planation stream piracy lies mainly in southern Monroe County, Indiana. .V topographic map of the locality accompanies this paper. The area as iMai>i)ed laps somewhat over into Lawrence County. Some seven square miles are included in the mapped area, the larger part of which lies in T. 7 X.. K. 1 W. The portion of the area in Lawrence County lies in the next township to the south. A small portion of the mapped area is included in the extreme southeastern part of the Bloomington Quadrangle area. The case of piracy is about two and one-half miles east of Harrodshurg station and just south of the little village of Fairfax. The area is some twelve to fourteen miles south of P.loomlngton. The area is cut by the intreiu^hed valley of Salt Creek. The valley on approaching the area from the north makes an abrupt turn to the west and northwest, and then again turns to the south when within three-fourths of a mile of Harrodshurg station. It leaves the area trending in a southeasterly direction. The.se abrupt turns in the valley of Salt Creek have given rise to an upland mass of land partly surrounded by Salt Creek valley. The individual drainage of the upland is by rather minor streams, chief among which are Upper and Lower Cut-off creeks. These streams are not more than two miles in length. Clear Creek which heads near Bloomington enters Siilt Cx'eek near the southwest corner of the mapped area. The area is rather sparsely .settled and most of the steeper slopes are wooded. The gently rolling upland area and the broad valley of Salt Creek are under cultivation, but no part of the area is attractive from the stand- point of agriculture. Topof/raphj/ and Relief. — The topography is shown specifically upon the accompanying topographic map which has been prepared to show the out- standing topographic features and their relationships. The area has a max- imum relief of slightly over 250 feet, extending from the valley of Salt Creek which has an elevation of about HOO feet to the higher parts of the upland which reach an elevation of 750 feet or slightly more above sea level. Towards the east side this maximum relief of 250 feet is attained immediately between the valley and the upland. The chief topographic feature is the deeply cut. but flat-bottomed valley of Salt Creek. This valley ranges in width from al)out one-fourth of a mile to a mile. In places this valley is flanked by terraces which are from 10 to 40 feet in height above the i)resent flood-plain. For the most part the upland rises abruptly from the valley floor with an ascent varying from 125 to 250 feet. The upland 252 Proceedings of Indiana Academy of Science. is sharply trenched by minor stream development. The npland spaces between the minor stream valleys are rather gently rolling or flat, with some development of shallow sinkhole topography. Geologic Conditiom and PhymograpJiic Development of the Locality. — Since an miderstanding of the geology of a locality is frequently quite essen- tial in the interpretation of the topographic forms present a brief sketch of the geology will be given here. The upland mass is comix>sed chiefly of solidified Mississippian rocks of Keokuk and Warsaw age, covered over with a thin soil mantle except where the slopes are quite steep. Small deposits of late Tertiary gravel are present on the upland adjacent to Salt Creek valley. Salt Creek valley is partly Idled with Pleistocene and recent alluvial material. The rocks of Keokuk age are massive to thin bedded iniimre sandstones and sandy shales, all usually of a bluish color, consisting of the upper part of the so-called Knobstone group of rocks. These sandy shales and argillaceous, fine-grained sandstones are mainly exposed on the steep slopes of the area. More than 200 feet of the Knobstone rocks are ex- posed on the steep sloi^es on the eastern side . of the area. Everywhere on top of the upland the clastic Knobstone rocks are covered with the thin to massive bedded Harrodsburg limestone of Warsaw age. The con- tact of this limestone with the Tinderlying Knobstone is about 740 above sea level at the east side of the area, about 650 feet in the middle of the area, and about 580 feet in the hill east of the mouth of Clear Creek near the southwest corner of the area. With these figures in mind, reference to the topographic map will show that practically all of the tillable upland is on the Harrodsburg limestone. This limestone has a total thickness of about 90 feet, but only in one or two localities in the mapped area is the total thickness to be found. This limestone area is covered by a red soil in and on which are quantities of chert which has weathered from the limestone. The dip of the Mississippian rocks may be computed from the figures given above on the contact of the Harrodsburg limestone and the Knob- stone rocks. The dip is mainly west, or slightly south of west. The rate of dip is variable, being abnormally great in the eastern half of the area. There, the dip amounts to something like 80 feet to the mile, while in the western half of the area the dip has subsided to approximately the normal amount of 35 feet to the mile. The extraordinary dip at the eastern side of the area is probably because of proximity to a considerable structural disturbance a short distance east of the mapped area. The region is a dissected plain. The topographic map shows distinctly the general level of the plain in the gently rolling to flat upland inter- stream spaces. This upland plain is about 7G0 feet above sea level at the eastern side of the area. It inclines to the west where it has an elevation of about G75 feet. This plain as preserved in the area is a portion of a more extensive one developed on the rather resistant Harrodsburg lime- stone which caps the upland area. The Harrodsburg limestone capping has protected the underlying easily eroded and weathered Knobstone rocks. Since this partly preserved plain' inclines practically with the dip of the Harrodsburg limestone upon which it is developed, it may be regarded as a structural plain. It may al.so be called a structural peneplain, since it is PldiKifion ^Iranii Piriir-i/. 2.":! ;i plain devolopod on tlu> slriicliii-al level of tin* IIarro(lshnr« limestone iiy Ihivial a.i,'encies. It owes its lU'eservation as a plain to tlio rather superini- resistance of the limestone Id mechanical denudation, and to the fact that its snhterranean drainage in llie limestone has temporarily greatly retarded lis tluvial destruction. Where the streams have cut through the Harnids- liiiri,' limestone into the mechanically non-resistant Knohstone rocks tliey are flanked by very steep slopes, having angles of 20 to HO degrees from the horizontal. This sliaip stream trenching is Muite characteristic of Knohstone topography. The structural plain developed on the Harrodshurg limestone extends miles eastward from th(> area, and rises directly with the strata in that direction. But less and less of the interstream surface is level to tlie east- ward; and tinally the Harrodshurg limestone ceases to be present, though the plain itself has risen leneplain, and may be cor- related with the Highland Kim pene])lain of Kentucky and Tennessee. The Highland Kim iieneplain renniants represent the highest level attaine:! in Indiana. In the region in question no part of the area reaches up to the Highland Rim level. P to it") feet high. This fall may have endured for some time, hut the nature of the rock is such that the fall could not have persisted. The rocks are easily eroded and weathered, and there are few or no ledges of superior hardness. The correction of this iRH-uliar gradient of tlie diverted stream has deei)ly entrenched the valley, having cut it some 90 to 95 feet deeper Ilia II the valley of the parent stream. Thus the Upper Cut-off Creek drain- age hasin furni.shes an excellent example of a stream basin that has been statically rejuvenated.* Migmiion of the Cuf-Off Col.- At the time that the parent Cut-off stream was divided into two parts by the lateral planation of Salt Creek the divide between the two parts \<'as probaldy immediately west of the place where the cut-off was effected. The rejuvenation of the upper stream basin was followed by its Intrenchment far below the former fairly well graded valley-level. Tiie tributary stream which comes in from the south near Phillips School was probably for a time a tributary to Lower Cut- off Creek. But the rejuvenation brought about b.v the piracy gave rise to a condition favorable fin- normal beadward erosion piracy. Rainwash and gullying on the west brought about the capture of the somewhat slug- gish stream from the south, thereby enlarging the basin of Upper Cut-off Creek. Headward erosion continued westward down the course of the par- ent stream, and the small ravines on either side were captured in succes- sion. The divide has now migrated by this headward erosion process about one-fourth mile west of its original i)ositioti at the time the planation piracy Fig. 3.

This successive piracy proceediufj down the cour.si' of the old parent stream will continue until the gradients of the new reveised stream and Lower Cut-off Creek are in a balanced condition. Thus Cut-off Col may be expected to migrate west of its present position prob- ably as much as a half-mile before the balanced condition is attained. The whole basin of former Cut-off Creek had an area of some 1,040 acres.

The main body (tf tlie pai>er deals with the details of the planation type of piracy. Following the method chosen by the writer as the most satisfactory method in presentin;; a physiot;iai>hic subject, a complete view of the area is j^iven before the details of the main subject are presented. The jjeographic position, the topo}j;raphic condition, the perti- nent fjeolofjio factors and the physiosraphie development of the area are liresented in order before the details of the stream piracy are undertaken. rianation piracy consists of the diversion of tiie upper portion of a stream by the invasion of its valley by the lateral planation of a neinh- borinj; stream. Tsually the diverted stream is a minor stream and the pirate stream is much larjier and is widening its valley by lateral plana- tion. The case dc^scribed is that of Cut-off Creek in southern Monroe County. Indiana, a short distance east of Harrodsbnrg. It is shown that till' topographic condition of the area, the cour.ses of the streams con- cerned, and the passage of glacial waters down the ctmrse of the master stream (though the area is distant from the glaciated portion of the state), were important factors favoring the development of the piracy. The principle of static rejuvenation is applied to the diverted and revived rpper Cut-off Creek. It is shown that the rejuvenation of the stream basin brou.ght about l)y its diversion gave opportunity for further piracy to take place; but pirac.v of the headward erosion type. The upper, diverted part of the parent stream lias grown at the expen.se of the lower part. I'lanation stream piracy is rather common. An excellent example is shown on the I.,ockport. Kentucky. Quadrangle, where Kentucky River has invaded the drainage basin of Cedar-Sawdridge Creek and diverted that stream S(»me three and one-half miles above its former entrance into the main stream. The lower portion of the divided valley is occupied by I'oiid Creek, a stream far too small for the size of the valley. Judging from the present gradient of Cedar-Sawdridge Creek, this stream at the time of its diversion was approximately tU) feet higher than Kentucky Uiver at the place of diversion. The old valley at the divide between Pond Creek and the .small reversed stream that is etching its way into the I'ond Creek .system is approximately (>(> feet above the Kentucky River. A potential case of planati(m piracy is shown on the Buckliorn, Kentucky. (,)uadrangle. which in many respects resembles Cut-off Piracy. Mace Fork Creek, like Cut-off Creek is small. It will be divided into approximately e(|ual i>arts. or rather far up stream. When the Kentucky River finishes culling the narrow divide between Mace Creek valley and its own valley. the I'piKM- part of Mace Creek will enter Kentucky River as a waterfall aipproximately 110 feet high, a fall similar to the fall of the newly diverted Ippi'r Cut-off Creek.

The ease of the Cut-off planation piracy is a clear one, as is shown by the accompanying topo- graphic map. It has in it all the phases of any case of planation stream piracy. For these reasons the Cut-off planation piracy may well serve as the type case of planation stream piracy. 261 WHAT IT rs "I'oi'- ix I'oi' couxv ■R. TT. f'AHK and K. F.

Theories o/ I'oppijif/. The writer formerly was led to think the cause and degree of popping was in proportion to the hygroscopic water contained in the corn when heated, but a little investigation convinces one that popping is quite independent of the water content except between very wide limits, besides other kinds of corn such as dent or sweet do not pop wide open ;it any moisture content. Some have thought the action to be similar to that of Professor Anderson's puffed corn or wheat, etc., in which the outer covering holds tenaciously enough to expand without breaking. This, however, is not the case with pop- corn as it is possible to di'ill holes in the grain or slit the sides of the hull with a sharp knife and still have the grain pop wide open on being heated in a proper way. Scope of Investigation. The study of this subject is still going on but the points investigated so far concern mainly the mositure and protein contents, percent of popping, time of heating for best popping, microscopical appearance of popped and unpopped corn and changes in composition after popping. The 50 corn samples tested were secured from various sources. Many were from the farmers who grew the corn, some were ol)tained in grocery stores in different Indiana towns. They were mostly of the rice corn variety. Some of the samples are known as Australian Hulless. and some as California Golden. The percent of moisture, pop and protein content of the samples are given in the table which follows : 262 Prorir(]inf/s of Indiiiini Ac(i(l( iiii/ of Srirnrr. Table 1 Shn inn<, I'm; ,// nj MniHi.

Mieroscoiiicdl (ind Clieiiiicdl Studies. In order to study the changes going on within the cells it was thought worth while to make some photomicrographs of a cross section of the pop corn grains both before and after being iMijtped. These differences are shown in photomicrograph 1, L'. 3 and 4. It will l)e n()ticed that the coll walls and the contents of the cells are very greatly expanded and more clearly defined in the popiK'd corn than in the unpopped indicating exten- sive UKtlecular rearrangement in the cellular structure. The chemical analysis seems to indicate that the most pronounced change 264 Proceedings of Indiana Academy of Science. due to popping corn is tliat whicli tlie starcli undergoes forming soluble stai-ch and dextrin. This is shown by the increase in blue color given by the iodine test for starch as well as by the increased solubility of starch and dextrin when extracted by cold water. It was found also that there is considerable increase in the amount of fat extractable with ether after the corn is popped. This is probably due to the thorough disruption of the cellular structure making more complete ex- traction possible. It was noted too that there is a slight increase in the tiber content when corn is popped. The action of malt diastase on the popped corn shows that over half of the starch has been converted to a form capable of reducing Fehling's solution. It is well known that a large amount of steam escapes when corn is popped but it is usually considered that this comes only from the moisture contained in the corn. This does not seem to be entirely the case. Since the loss in weight on popping is slightly greater than that of the moisture in the corn, and since there is no carbon dioxide gas produt-ed. the exces- water may come from a partial breaking down of the starch molecule to a less complex structure through the loss of water of constitution as shown in the table which follows : Table 3 Showing the Loss of Water of Constitution in Popped Corn Percent Percent Percent of Sample No. Moisture Loss on Water of Popping Constitutioi A 7.96 8.68 0.72 B 10.21 11.71 1.50 C 8.56 9.60 1.04 D 14.31 15.50 1.19 E 14.04 14.50 0.46 The change taking place seems to be one of hydrolysis due to the action of steam under a considerable pressure. The cellular starch wall is very elastic permitting of wide distention, and loss of some cell granules, without breaking. Other corn grains split open without much cell elasticity being shown. Summary. I. The amount of moisture is not the determining factor in popping of corn except in cases of extremes wet or dry samples. II. The time consumed in popping corn is an important factor; when heating has been too rapid the corn does not have a chance to become dextrinized throughout the grain, when heating is too slow the moisture content becomes too low to explode the grain. III. Photomicrographs of popped corn show the cells to be greatly enlarged and a considerable part of them disrupted releasing some starch .granules which may be stained blue with iodine solution. IV. Popping corn increases the ether soluble fat, also the soluble starch and dextrin and deci'eases the starch while the fiber is slightly increased. V. The popping of pop com seems to be caused by the multiple cell ex- plosion of steam derived from water of constitution and from hygroscopic moisture.

Can it be that we are now to lose also the research spirit, to lapse into the mere "business as usual" habit of considerini: of value only the investiga- tion that makes for immediate profit? Whatever the answer to this (piestion may be. it is irenerally conceded that scientitic researcli cannot go on. either with or without nniterial support, unless we can someliow continue to give to an intelli.gent and able body of men and women wlio have shown si)ecial ai>titude for this kind of work, special training in the necessary methods of scientitic investigation and, at tlie same time, to inspire them with enthusiasm for this high sort of endeavor. Quoting from a recent circular issued by the National Research Council. "It" (the Council) "hopes to encourage the interest of universities and colleges in research work and workers so that the inspir- ati(m and training of American youth for scientitic work may never fall so low as to threaten to interrupt the constantly needed output of well- trained and devoted scientific talent in the land". This brings us, at once, to the examination of the ipiestion of what things are necessary to provide opportunity for such training and of what w^e in Indiana are now doing in the way of providing this opportunity. I have a notion that what I am here to say will apply in cohsiderable measure to nearly all branches of pure and applied science. But In ortter to forestall if possible, certain criticisms that I might, through ignorance, be unable to meet, I shall confine myself to the one matter covered by the subject of this paper : the training of chcuii.its for research. My first proiKisition is that such procedin-e must be based ujion a very broad and thorough drill in the fundam(>ntals of the science. Xo chem- ical researcli problem, however narrow or limiteproa<'h t<» a recoj;iiition of the possiitil- ity of any other fine thin;;, the herabliiiK of whicii nu«lit serve to attract a desirable class of prosju'ctive students, or to win the support of pul)lic oi)inion and puidic purses. Ajiparently no one thoujibt of a high class. t such training, in the ma.iority of cases. Real research is a long, hard, toil- some business, ricli in rewards but calling for preparation, energy and ap- lilication such as the average inidergradiuite does not pos.sess. Far better to keej) him on the fundamentals of pure and ai)plied .science, of which be will absorb a woefully small amount under the best conditions, than to give him the false notion that after a matter of three or three and a half years of intermittent study of an intricate and ccmiplex science, he is pre- pared to .solve scientific itroblems that have liatlled others, or even to know how to try to solve them. The undergraduate thesis, in the large ma.jority of cases, is little more than a piece of more or less mechanical f(dlowing of directions given by tlu" su] lervising professor, and it rarely devehtp-; any dependable results that may be coiisidercMl ;is new. It is conceded that the material may be new to the student and that the iisychological effect may thus be desirable. Hut so are all of bis studies new to him. They are all. for him. original rese.ircb in i>ractically the same sense that the the-is investigation is orig- inal res(>arcli and if. in his regular studies, he is properly directed in the u.se of the library and if the in>-piration to real study is provided, there is little real difference between the thesis and the regular study, so far as this sort of training is concerned. /'r(i(( rtii ii(/s of 1 11(1 Id 11(1 Acddcini/ af SciciK ■m-jHlnatcs will r;iivli and will ■r pursue lie that a then iicv.T have any tiaiiiiii- at all in ii.'Ncr .'liter this lield. since a (■(inipara lively small iira.liiale studies.

Our chemical graduates ar(> a si»leiidid as.set to the State and to the nation but their work, for the most part, lies elsewhere than in the lines of research. It is my perstmal belief that Inecimen subjected to the same strain. Plate III shows the same thing for aluminium. Plates II. IV and VI show tliat for all three metals investigated the larger the stress applied, other conditions being equal, the greater the recovery. Plates I. Ill and V show that the longer the time of applying the stress the greater the recovery, the stresses being equal. It will be noticed from these same curves that per unit of length per unit of stress the amount of recovery of the different metals is in the same order as the tempei'atures at which the metals annual. All these facts support the hypothesis that the reco\ery of a metal after the stress has been removed is connected with the process of recry- stallization. In the first instance the material of a drawn wire that has not been annealed is largely reduced to the amorphous phase. Such crystals and parts of crystals as remain are under strain which is the result of drawing. Most of the strain was relieved when the tension of the drawing process was released. But the fine amorphous particles fill the spaces about the remaining crystals leaving the metal still in a state of strain. Annealing or recrystallization immeiliately begins and the amorphous [tarticles begin 282: Procccdiiif/f; of Iiidiand Acdihniij of Science. to attach themselves to surroitncling crystitls. As the crystals huikl \ip there is a shrinking in the length of the specimen. This shrinking continues until the more easly occupied si)ac('s are filled, the displac-ement gradually be- coming less and less until it is not detectable. Rut there is still strain left for not all metals anneal perfectly at ordinary tcnii)eratiiix's. When more strain is produced by applying stress there is an agitation of the particles of the metal and the shrinking starts again. ;is soon as the stress is re- moved. Since in the drawn wire a large ikm- cent of tlie metal is in the amorjihus phase it is only logical to expect that there would be a greater recovery for a given immediate strain thaii in jiii annealed specimen. It is easily seen from this viewpoint how increased stress and increased time of applying stress produce greater recovery. Starting with an annealed specimen, the greater the stress applied the more crystals there are broken down and the more anioi-jihous substance there is to take part in the process of crystal formation, hence the greater contraction. The same argument holds for increased time of applying stress. There is no legitimate l>asls of comparison of the rai>i(iity of contraction of two different metals. A susi)ended alumirnuni wire a meter long meets but comi)aratively little opl>osition to contraction due to its own weight. A piece of lead wire a meter long suspended by one end. when freshly annealed flows of its own weight. This indicjites the great force that must be over- come, in the case of lead, by the forces of recrystallization. even to main- tain the original lengtli. Since exiierimental results show that there is actu- ally greater recovery for lead ]ier unit of length per unit of stress applied. other conditions being the .same, in spite of this handicap, than for either copper or aluminium we .see how much gri-ater nuist l)e the forces that cause the shrinkage in lead. l>ut lead anneals ]ierfectly at ordinary tem- peratures, aluminium at higher temperatures and coi)i)cr at still higher temperatures, just the order that must be expected if recovery is to be accounted for by recrystallization The fact that greatest recovei*y takes place where greatest activity of iccrystallizatiou is involved is a strong point in favor of the hypothesis that the one is (U-pendent on the other. This idea fits exactly Prof. :MiclK'lson"s ( .". ) picture of elastlco-viscous recovery. The force that causes the shriidvage is an elastic force but pro- duces no instantaneous effect for just the same reason that a rubber band stretched on a block of wood cannot contract to its original length. But cause the block of wood to contract gradually l>y any means whatsoever and the rubber band follows it. In just the same manner the elastic forces which are contained within the remaining crystalar structui-e cannot act because they encompass the amorphous phase of the material. lint let, this phase begin to reform into crystals. It is wedged between the crystals and fills all the spaces between them. As it joins neighboring crystals or forms new ones the original crystalar structure begins to make a readjust- ment because of the strain which it is under. The more active the amor- phous idiase is the more rapidly the whole structure contracts. Such a conception of tlu' state of a metal after strain will account for what I'rof. Michelson (o) calls "Lost ^Motion"', the failure of a sti'ained metal to return to its original confignnition when the stress is removed. It is found that the more nearly perfect the process of annealing is, the greater Cojiiirr, Alii iiiiiiiini , (ind Lciiil. 28rj is the "LosI Molioif.

A LOX(; WAVE RECEIVER. R. R. Ramsky. In wireless work all wave lengths are used fi-om 200 meters or less, anialures. to 20,000 meters in transcontinental transmission. It is cus- t(imar.v to limit the wave length range of reception of any receiver to a com- parative small band of this range. This is due to the fact that in order to keep the natural frequency of the coil high. Avhich involves the necessity of the distributed capacity of the coil being low, it is usual to wind the coils with one layer of wire. Single layer coils in order to have a high induc- tance must be made of large dimentions of very fine wire which necessi- tates a very large resistance. In the coil which I have made I have endeavored to avoid this ditficulty by winding the coils of relatively large wire in banks or coils one inch in width and five layers deep. The distributed capacity is kept to a low value by separating each layer by means of heavy card board. The coils are wound on card board tubes whose length is seven inches and whose diameters are. primary coll 14 cm. and secondary coil 10 cm. Each coil con- sists of six banks one inch wide, five layers deep. Each layer containing twenty turns of No. 20 wire. The total number of turns per coil is 000. The original design of the coil called for No. 24 wire 30 turns per inch or about 1.000 turns in all. This would give an inductance of about .07 henrys or a wave length of about 20.000 meters using an ordinary .001 microfarad condensed. The smaller wire was not available so the larger wire was used and the lack of inductance was made up by using a variable conden.ser whose maximum capacity is .01 microfarads. On the secondary coil ten taps are brought out. The taps are arranged as follows. Tap No. 1 contains 1 turn ; 2, 3 turns : 3, 7 turns ; 4, in turns : 5. 1 layer : 6. 2 layers ; 7, 1 bank : S, 2 banks ; 0. 4 banks ; 10. the entire secondary coil. Cut out or dead, end switches are inserted between taps No. 0 and 7. and taps 8 and 0. The windings of the primary are arranged after the same plan as that in the secondary except that ther(> are S taps instead of 10. The coils are mounted so that the secondary will slide into the primary coil according to the well known plan of the slide tuner. A feed back or regenerative coil of 425 turns of No. 30 wire is mounted so as to slide into the primary coil from the opiM)site end from the secondary coil. This coil is seldom used as it is found tliat an "auto feed back" connection on the .secondary gives better results. This consists of a switch by means of which the filament of the tube can be connected to a point near tlie middle of the secondary coil. The diagramatic connections are shown in figure 1. 290 ProcrrdiHys of fndiana Academy of Science. The tnning of the primary coil is liy means of a variable condenser in series or in multiple witli all or a ]»ortion of the primai'y coil. The inductance of the coils as wound is secondary, .0185 henry ; and pri- mary, .0228 henry. The total resistances are, 8.1 ohms and 9 ohms re- spectively. The natural wave length of the entire secondary coil as meas- ured with a wave meter is 11(M> meters, which corresix)nds to a distributed capacity pf .000019 microfarads. The dead end switches break this so that the energy ab.sorbed is a minimum. As mounted as a slide tuner the length over all is 22 inches. The total weiglit is 15 pounds. An equivalent long wave receiver coil of the single layer type would require five times as much wire and would be 25 times as long or a length of about 45 feet. Thus we liave in small dimensions a receiver for any wave length from Ainiapolis 17000 meters to amateur stations 200 meters. European sta- tions are received with one liulb using an aerial 125 feet long stretched among the trees of the Indiana University campus. 291 SlXiKKtJATlON A.\l> KJ':('().MI'.lNATION OF THE (iENKS FOR TINGED, niAMHK lU'FK.

If the different mutants are a result of losses of materials that lie at different levels on the sex-chromosome, then the wild type eye should result in the daughters on crossing any two of the.se mutants, since the daughter receives two sex-chromosomes and each would restore the missing allelomorph of the other. As a matter of fact the daughters from all combinations are com- 292 Proceedings of Indiana Academy of Science. pounds, with eyes intermediate in color between tlie parent types. If the Kenes for these different eye colors are allocated at different levels f)n the sex chromosome there should appear among the grandsons eyes of the wild , type as a result of the phenomenon of crossing over.

The genes for buff and coral known to be allelomorpbic to white have here been tested with tinged and ])lood. two otlier genes allelmorphic to white. The exr>ectation is that since both are allelomorphic to wlaite, tlaey will be allelomorphic to eacli other. The results of the different combina- tions made verify the expectations. Sufficient evidence has accumulated to show that these are members of the same allelomorphic series. The fact that tlie red eyed fly does not appear in the Fj or F. bears out the assumption that the different members of this multiple allelomorph series are but different expressions of the same material particle and that they occupy identical loci on the sex-Jiromo.some. 0.

These when inbred gave in the F, generation 107 curved and 348 wild tyi>e flies. Table I. Both sexes are affected. This result demonstrates curved to be a reces- sive, non sex-linked mutant giving a Mendelian ratio of approximately 3 to 1.

Summary. The independent origin of curved, a wing mutant identical with the one reported by Bridges, is liere given. Tlie data obtained witli the various crosses is in agreement with the great mass of evi- dence which shows that the chromosome conception of inheritance offers the only rational basis upon which such data can be interpreted. Genes carried by different chromosomes give free assortment with Mendelian ratios, those in the same chromosome show linkage with no crossing over in tlie male. It is evident that the factor grouping of a new mutant can be determined by the failure of the double recessive to appear in the F., generation. Mor- gan has made use of black-pink flies for testing a new mutant type. Black is in the second group and pink in the third. If tlie new factor belongs to either of these groups it will fail to show the double recessive among the grandchildren from the cross. The sex relations from such an exjieriment will readily determine whether or not it belongs to the sex-linked group. If it belongs to none of these groups it is by exclusion placed in the fourth group. l>i-(>s()/)ltihi Ml IdiiDi/iislrr. ;ilo I//. lAlvniliirc. 1. M(irj.Mii. Sturli'Viiiit. .MiilhT, r.iidtics.

Director of tlio Musouni of tlic ( "iilifiiriiin AcMdciiiy of Sciences. It has been my aiin to l)rin.e; toKetlier and put on rccm-d in tliis paixT such notes as I now have conceniiiiK the birds of Carroll. .Monroe, and Vi^'o counties. Indiana. I bejian recording my observations on the birds as long ago as 1877. The greater part of the records made prior to 1888, were, how- ever, lost in the tire which destroyeirds was merely such as is taken by most country boys with a more or less decided "bent" for natural history. In the s])riug and summer of 1877. my wife. Meadie Hawkins Everniann. was a student of Dr. David Starr .Jordan's at liutler University, and. through Dr. .Jordan. Mrs. Susan Bowen .Jordan. Dr. and Mrs. Alembert W. Brayton. and Mr. Charles H. Gilbert, all of whom then lived in Irvington and all of whom were then enthusiastic collectors and students of birds, she. too. be- came interested in natural history, particularly botany and ornithology. From them she learned to skin birds and when we I'eturned to Camden in the fall, I also became interested in natural history studies, and from that day to this we both have retained our interest in birds. Our tield work in Carroll County was chiefly in the vicinity of Camden and r.urlington ; however, from March. 188.",, to .July. 1885. my work was such as took me. in buggy or sleigh, all over the comity. I was thus a tield (III i»ractically every day continuously for nearly two and one-half years, and thus had exceptional opportunities to observe the birds in every part of the county, during all seasons and at all times of the day. Mrs. Evermann was constantly and enthusiastically associated with me in all this work, sometimes accompanying me on long trips over the county, more often joining the short trips afield. She always joined in the study and identifi<'a- tion of the specimens collected and did practically all the taxidermy work incident to the preparation of the specimens. Among our students were several that became more or less interested in birds and who assisted us in field observations and the collecting of speci- mens. Among these I may mention particularly the following: First of all. Ami. Addi.son. Sidney T.. and Otway C.. Sterling, four brothers living south- west of Camden on Bachelor Run. all with a natural history "bent". Ami and Addison, fine young boys they were, and promising yoinig naturalists. 316 Proceedings of Indiana Academy of Science. made a small collection of nests and eggs, which doubtless would have grown to considerable size and value if the boys had lived, but they both died while yet in their teens. The other two brothers also were good observers and I am indebted to them, particularly to Sidney, for many records of rare or uncommon birds noted. Frank C. Porter, a cousin of the Sterling boys, and living on a farm near them, also was interested in birds and contributed many observations of value. I spent many a day pleasantly with these boys hunting in the Deer Creek bottoms. My nephew, Edwin C. Evermann, of Burlington, another promising young naturalist who died while yet a. boy in 1888, made a small collection of bird eggs which is now in the Museum of the California Academy of Sciences. Two other Burlington boys who showed some interest in birds were the brothers, William and Dalton Wright now of Los Angeles, California. Still others who have communicated to me observations or data of value, or specimens, may be named : D. C. Ridgley, now professor of geography in the state normal school at Normal, Illinois ; Harry C. A'an Der Volgen of west of Pittsbvu-g; James Milton Beck (my brother-in-law), of Burlington ; Miss Ava Evermann (my niece), then of Burlington, now of Kokomo ; and Frank C. Groninger, one of our students at Camden, now a prominent lawyer of Indianapolis. And recently my young great nephew. Donovan Beck of Bur- lington, has sent me notes and specimens. Favorite collecting places about Camden wore the following: Along Deer Creek in the woods from the Vandalia railroad to Leonard's mill, a distance of two or three miles; the woods and hillside thicket at the southeast edge of Camden ; the Deer Creek bottoms from Camden to below the Porter mill, a distance of perhaps three miles ; along the lower course of Bachelor Run ; in the heavy forest on the AVise farm southwest of Camden ; on and about the Wm. R. Stewart farm southwest of Camden ; in the open woods just north of the Frank Thomas farm south of town ; in the woods northwest and north of the town ; and about the Armstrong pond at the south edge of Camden. The localities about Burlington most frequented were the following: My father's farm and the farms adjoining it. about a mile south of town ; along Wild Cat Creek from a mile below Burlington to the dam about the same distance above town : and the Maple Swamp near Lexington. Many ob- servations were made also along the road between Camden and Delphi and along the Wabash River near Delphi. Monroe Covxty. From August, 1881, to March. 1883. and again from July. 1885, to July, 1886, while students in Indiana University, we devoted much of our spare time to the birds of Monroe County, particularly of the region within a radius of 15 or 20 miles of Bloomington. During those years our pleasure and enthusiasm in ornithological studies were increased through associa- tion with several other students of kindred tastes. Among these may be mentioned the following : Willis S. Blatchley, afterward teacher of biology in the Terre Haute high school and later the able State Geologist of Indiana for many years: Charles H. Bollman. a very promising young naturalist interested chiefly in myriopods but also deeply interested in birds and fishes, Xotrs on the Hirds. 317 whose untiiuoly dfalli mI Wiiycross, Georgia, July 1."'..

All of lliese were then enthusiastic students of birds and all would no doubt ha\-e atlained dis tinction in ornithological studies, had not the Fates east their lines in other fields. Vico County. "While residing at Terre Haute from July. ISSti. to July. ISOl. our interest in ornithology continued an(i we were able to pay considerable attention to the birds of the region within a radius of some 20 miles of Terre Haute. During the school year it was my custom to spend Saturday of each weeli somewhere in tlie country, a practice which was IvOpt up regardless of weather conditions; rain, storm and snow were never permitted to interfere. TTsually accompanied by one or ukuc of my students, I would drive afield early every Saturday morning, .spend the day in woodland, along some stream, or in and about some pond or swamp, returning home late in the evening, or frequently not until the next day. The late Dr. Josiah T. Scovell. an all- round naturalist, was my companion on hundreds of trips, and a more delightful companion, or one more enthusiastically and intelligently inter- ested in all nature, no one ever had. Dr. Scovell's interests were many. Indian mounds, old river channels, the evidences of glacial action, the geol- ogy of the region, the soils, building stone, coal mines, oil, the topographic features of the county, — in short, everything geologic, geographic, topo- graphic, hydrographic, and climatic, interested him ; and his knowledge of these subjects was such as enabled him to discuss them all intelligently and interestingly. He was also a good botanist and a fair zoolo.gist, especially Interested in ecological relations. In systematic zoolog.v lie perhaps knew most about the freshwater mussels (the Unionidfe). but he also knew a good deal about the local birds. The hundreds of trips I took with Dr. Scovell over Vigo County I look back upon as among the most delightful of my life. Among my students who took special interest in these trips I may be permitted to mention a few : Ulysses O, Cox, for many .vears head of the department of biology and dean in the Indiana State Normal School whose untimely death at Denver. Colorado, August 20. litJO, took from the faculty of that institution one of its ablest, most useful and best loved members; J. RoUin Slonaker. a boyhood chum of Cox, now assistant professor of physiology in Stanford University; L. J. Kettger. now head of the depart- ment of physiology in the Indiana State Normal School ; D. C. Ridgley, now 318 Proceedings of Indiana Academy of Science. head of the (lepartiueut of geography in the Illinois State Normal School at Normal; Be.ssie O. Cushing (Mrs. D. C. Ridgley) ; Flora Hartley, now wife of Dr. Charles W. Greene, professor of pliysiology in the University of Missouri; Albert J. Woolman, for many years a science teacher in the higli schools of South Bend and Duluth, later business man in Urbana, Illinois, who died in 1018 ; Thos. F. Fitzgibbon, now prominent educator. sui>erin- tendents of schools, Muncie, Indiana ; Cloudsley Rutter, for a number of years one of the most able scientific assistants in the United States Fish Commission, wliose death in 1003, deprived ichthyological science of one of its most promising young men ; J. C. Cunningham, now prominent farmer and business man in Miami County ; and \V. I). Hamer, prominent lawyer at Huntington. Many others might be named. I must not forget to men- tion my life-long, most intimate friend and predecessor in the Indiana State Normal School, Dr. Oliver 1'. Jenkins who, though at DePauw University, frequently came over to Terre Haute, and many a delightful trip did we take together along tlie Wabash and its small tributaries in search of things in which we were both interested. Dr. Jenkins was also deeply interested in the birds of Vigo County, and at one time liad in mind the publication of a report thereon. Mention must be made also of W. S. Blatchley who during the several years of his connection with the Terre Haute high school, gave much attention to the natural history of Vigo County. I regard the following annotated list as valuable chiefly because of tlie records of definite dates and places. To some, these may seem trivial and of little consequence, but to the future student of the migration, geographic dis- tribution, and habits of our birds, it is believed they will serve a useful pur- pose. A statement that a certain species was seen on a certain date in a certain place does not mean that it was not seen on many other dates and in otlier places ; it simply means that that particular note was not lost in the fire of 1888. While these records are, in many instances, unrelated, they will, nevertheless, it is believed, prove useful. I have advisedly made the rec- ords as definite and detailed as possible as to dates, places, persons and cir- cumstances, in the belief that their value will thereby be enhanced. It is regretted that the Vigo and Monroe counties records are not more numerous, but it was the note-books of those comities which were most completely lost in the fire of 1888. I am glad to mention the considerable number of my former students and associates whose observations and assistance in other ways have contrib- uted to our knowledge of the birds of Indiana, and I take this opportunity to express my high appreciation of their interest and helpfulness. Without their comradeship afield, which gave opportunity for discussion and ex- clijinge of views, much indeed would have been lost. Annotated List of Species. In the following annotated list of species the nomenclature and sequence agree with the last (third) edition of the Check-List of North American Birds published by the American Ornithologists" Union in 1910. The species and subspecies are numbered consecutively. The number in parenthesis following the scientific name is the serial number of that species in the Check-List. Notes on the liinJs. 319 1.

The most common and best known species is the Pied-hilled Grebe, other- wise known as lielldiver. dabchick. or waterwitch. It is a summer resident in the ponds about Terre Haute and elsewhere along tlie Wabash River.

When at the Goose Pond, nine miles south of Terre Haute, May 3, 1S90. Mr. U. O. Cox and I found a nest of this curious, witch-like little diver. It was a floating ma.ss of dead flags and Scirpus stems, more or less matted together with mud. The eggs, of which there were seven, were covered up with nest material when found, and were very dirty. Incubation had slight- ly advanced. Four of the eggs measured, in inches. I.(;(;xl.l2. two 1.70 x 1.12. and one 1.66 x 1.09. • Doubtless other nests could have been found in this ikukI had we searched thoroughly. It no doubt nests in the Five-mile I'ontl. in Greenfield Bayou, and in other similar places in the comity. Carroll Count)/: A few said to remain through the winter in open places in the Wabash near the Georgetown mill. I do not remember ever to have seen it on Deer Creek or Wild Cat, but it was seen on the Wabash occasion- ally. On February 21. 18Sr». my friend. Charles Metsker. saw one in the Wabash near the Pittsburg dam. and Wm. Coble told me that a few usually remain all winter in air-holes in the Wabash near the (jeorgetown mill.
