BUSINESS Magee EOE the bureau OE ENTOluOlOGY

me have all been impressed, I am sure, ivith the increased complexity
in recent years of the administrative v/ork of the Bureau as relating to ac-
counting, the Budget , publications, efficiency ratings, etc, .after care-
ful consideration, and in consultation with my various associates, as to
what could bo done to further facilitate the work of the Bureau, it has been
thought advisable to'bring a nan of scientific qualifications into the busi-
ness administration of the Bureau, On account of his especial qualifications
I hav^. re^luested kr, S, ii, Eohv/t;r to take on the duties of Business kanager
of the Bureau, in addition to his administrative duties as head of the Tax-
onomic Division, quartered in the National kuseum.

The position of A^-iinistrative . Consultant in the Bureau is estab-
lished, kr, . E, Bt O'Leary , by reason of his 'wide experience in the Bureau
and his special knov/ledge of Bureau procedure, has been chosen to fill this
position,. He will assist in various matters which are referred to him in
regard to the .general business administration of the Liireau; ivill act as
advisor o.n matters of inter-Bureau and inter- Departmental contacts, .and do
research on business methods leading to efficient procedure* I must take
this opportunity to express to all of you my very hi^ regard for kr, O’leary
and mygreat ieeling of debt to him, not only personally but ofiicially, for
his absolutely untiring efforts during the long years that he ha’s played a
most important role in the constantly increasing and most intric.ate and
puzzling aspects of Bureau administration, »»ith this partial reorganization
he V7ill be relieved of -much detail and will be able to concentrate on the
larger questions in which the counsel . of his able and experienced ir.ind will
be necessary.

SIQREj>PROjJLTCT INSECT INVESTIGATIONS

E. A. Back, Senior Entomologist, in Charge

S< E*. McClendon spent a portion oi April in Louisiana, visiting sev-
eral large plantations vmere yeaily ohservations as to corn weevil condi-
tions are under way. Plantation managers arc glad to see Mr, McClendon,
for the Bureau's advico is easily translated into profits reducible to
dollars and cents. The ov/ners of one plantation claim that after putting
the Bureau's information into practice they saved 3,000 bushels of com a
year*

Lloyd E* Jackson, Senior Industrial Eellow of the Mellon Institute
of Industrial Research, University of Pittsburg, visited the laboratory in
April to learn the latest developments in experiments with so-called moth-
proofing solutions containing quinidine oluate*

The Millers Review and Dixie Miller printed in its April number a
portion of Department Bulletin 872, "Insect Control in flour Mills,"

Early in April rhe Supply Division of the U. S, Veterans Bureau had
bales of army blarjicets from its Chicago warehouse forwarded to Washington
for examination and advice as to condition and protection from fabric pests*
the protection of 100,000 blankets was involved*

At the request of G, C, Hubbard, Research Associate of the National
Association of Dyers and Cleaners, and of the Textile Section of the Bureau
of Standards, tests V7ere started and completed in April to determine whether
coatings of various proportions of paraffin diesolved in naphtha had any
value in rendering fabrics and furs immune to attack by fabric pests. Un-
fortunately, the paraffin was found to be of no appreciable value,

J, C, Hamlin and w, D, Reed, of tne Dried Emit Insect Investigations,
have an interesting article in the April issue of the Journal of Economic
Entomology, entitled "Insect Revival After Eumigation,"

On April 8, J, C, Bridwell, formerly of rhis office, arrived in New
York after a sojourn in India of two and a half years, Mr* Bridwell states
that he collected in India abotit 40 species of bmchids, representing 33
unrecognized species, and including 6 undcscribed genera, Mr, Bridwell
brou^t back to this country the bmchid Collection of the ivysore State, en-
trusted to him by Dr, Kunhi Kannan, and the bruchids of the Madras Presidency
loaned by Rao Saheb Ramachandra Rao of Coimbatore, Mr, Bridwell arrived in
Washington April 28,

In the April number of "The Bulletin," issued exclusively for the
members of the National Retail Dry Goods Association, is an article covering

five pages, "Eur Storage by the,. Eumigation Method," by A. Einstem,

Manager of the Merchandise Managers. Group, The purpose of this article is
to discuss the fur-stbrage vaul.ts of Bullocks, Los Angeles* largest depart-
ment store. ' The system, developed from advice received from this Bureau,
couples ti^t storage with fumigation, and. supplants the more costly cold
storage units in a modem establishment. Department stores throu^out the

•- 3

country are keenly intel'ested in this new development, for it is much less
expensive than the method in use. About one and a half pa-ges are given
to printing an extract from a statement solicited from this Bureau,

E, H, Lane, President of The Lane Compan.y, of. Altavista, Va. , the
largest manufacturer of cedar chests in .America, called in April to learn
the result of the Bureau's experiments to determine the comparative value
of chests ' of ' solid red cedar , as compared with those of other V70ods contain-
ing a'linihg.’of cedar veneer.

This' Division has , recently learned from its correspondence with the
Exporters and 'Importers Adjustment Bureau of New. York that in the latter
part of 1926 sto red-product insects caused a loss- of more than Jp50,000 in
the export flour business, •

E»’ A. Back spent' April 9 in Philadelphia, where a long-term experi-
ment is in progress in' a ■woolen factory, having fo,r its object the, elimina-
tion of losses caused by cl<2>thes moths. It is claimed that, these losses,
amount to about 'if 3, 000 per month.

Dr, Johns, of the Standard Oil Company, visited the Bureap. in April
to learn the results of certain experiments with mothproofing solutions.

One furniture Virarehouseman doing a large business recently wished
advice as to which of two chemicalsin crystalline form was the better for
his purpose,, ■ ®ae Bureau's.: experiments have .indicated that the chemicals
were of practically the same value. Since one costs 75, and the other only
7, cents per -pound, the adviee given meant a ’worthwhile saving in the
correspondent 's. storage plant,

C, -fV,' Dipraan, Editor of the Progressive Grocer, recently submitted
for criticism .by this Division an article by E» P, Linder, entitled ’’Don't
Let the Weevils ' Eat Up" Your Profits and Reputation,” . This article, pubHshed
in April,.? claims- that grocery interests suffer an annual loss of 4>200,000,000
throu^ the. attack of sto red-pro duct insects,

■ ■ Hon, Harry A, McBride., Vice Consul at Malaga, Spain, was a caller
in the latter part of April, He was particularly interested in obtaining in-
formation regarding attacks of insects on Spanish raisins and almonds* Ship-
ments of almonds from Spain in 1926 arrived et their destinations more badly
infested than usual. It was interesting to learn from Mr, McBride that
directions for fumigations, given several years ago to Malaga interests, had
■resulted in routine fumigations in almond warehouses,, and that losses caused
by sto red-product -insects • to almonds in transit have been greatly lessened*

Donald L. AKieffer, in -an article entitled ’’Bean Weevils Are a Com-
munity Problem”' ‘appearing in the Pacific Rural Pres-s^ for April 9, stated that
in 1926 bean v/eevils wore responsible for a loss to fanners in San Joaquin,
Stanislaus, and Merced. Counties , Calif., of from one to one and a quarter
million dollars. About 70 per cent of their consignments of beans virere found
on the'i-r arrival at warehouses to be infested .with these insects* ” It is
now,.,tho pr^tice for dealers to knock off fifty cents per hundred when they
buy in these counties,, fearing fumigation will not provide sufficient insur-

ance against rejections of the ^reconditioned* stock when it gets east.

Then if the eastern 'bu5'"er does reject, the California dealer, i/ithout much
protest, passes him fifty cents a hag to adjust the error. If there is
no rejection the dealer ar this end is iu pocket that fifty cents. The
grower of - those beans is out just rhat much anyway, * , .Tiiat is a little
of the tax he has to pay for having bean weevils on his place, in his
thresher or in the warehouse where he stores his beans, , . . , »Honest
cooperation between growers, dealers and warehousemen must come. . , •

The weevil problem is squarely up to Stanislaus, San Joaquin and kerced
Counties to straighten out by community cooperation," , This is an old story
to A. 0, Larson and C, K, Fisher, v/ho have developed and preached these
facts that others are now making their ov/n, mhen in Stanislaus Co\iQty this
month Mr, Larson spoke of the weevil situation before the Turlock Chamber
of Commerce, a special committee for the co\mty Board of Supervisors, the
Agricultural Committee, the Iviodesto Chamber of Commerce, and the County Farm
Bureau, The development 'of community effort . based on information resulting
from tedious examinations of warehouse receipts and samples, and the examina-
tion of beans on various' farms was part of Mr* Larson’s program while -check-
ing up on conditions in Tegner., Turlock, kitdiell, Keyes, Bonair, Hughson,
Fairview, Patterson, Paradise, Salida, Prescott, Geres, and Mt, View,

FOREST INSECT INVESTIGATIONS
F, C.' Crai^ead, Senior Entomologist, . in Charge

In the latter part of March F, C, Craighead and J, a, Beal spent
some time on the Choctowhatchee Division of the Florida National, Forest,
making a preliminary study of the turpentine borer (BuprcEtis apricans
Hbst,). This insect causes serious losses in longleaf and slash .pines
after they have been operated for turpentine. The more conservative types
of operating adopted by 'the Forest Service prevent much of this damage,
though faces exposed for a number of years are finally attacked*

Early in April R* A, S't, George and J, A* Beal began the summer
work at Bent Creek, the location of the field laboratory near Asheville,

N, C, It was found that low temperatures in the past vvinter had caused a
hi^ mortality in overwintering broods of Dcndroc tonus valons.

Dr, T, E, Snyder' left Washington on April 5 to make an inspection
of black walnut gun-stock blanks, and other timber, all infested by Lyctus
powder-post beetles, and stored at Rock Island Arsenal, Rock Island, 111,,
for the Ordnance Division of the War Department* On his return trip to
Washington he stopped at the Forest Products Laboratory at Madison, uis,, to
consult the Forest Service officials regarding cooperative v/ork on tests
of wood preservation, and returned to vnashington April 9,

niilliam Middleton left tjashington .cipril 19 for a short trip to
Willow Grove, Pa,, to study the results obtained in' fumigation of boxvvood
for the boxwood leaf miner. He returned to Washington on April 25,

TAXONOMI G INVEST I GaTIONS
S. A, Eohwer, Senior Entomologist, in Charge

The finding of Gryllus domesticus in great ahundance in Ba-ltimore,

New York, and various other localities in the eastern part of the United
States has heen reported, hut no specimens have been received for the Na-
tional Collection, V/e would like to have a long serie_s of specimens of
both sexes in adult and nymphal stages* It may be distinguished from the
other species of Gryllus by its generally lighter color and by the tv70 black
bands across the forehead*

T» H# Colbrook Taylor, who for the last three years has been engaged
by the British Government in the study and importation of parasites for the
control of insects affecting the coconut palm in the Fiji Islands, recently
spent a few hours of a short stay in Washington consulting with various
specialists in the Museum regarding features of his work* He was on his way
to his home in England for a vacation, Mr# Taylor reported that the estab-
lishment in the Islands of a certain tachinid fly» as a parasite of a moth
which was tlareatening to destroy the copra industry, had proven a phenomenal
success, the moth having been reduced to a point where it was no longer do-
ing any damage* '

Donald Hies, of Ithaca, N* Y, , visited the Division of Insects on
April 7 and 8, consulting various specialists and conferring with Mr. Rohwer
on sav7flies of the family Siricidae, on v/hich he expects to 7rrite a thesis
for a doctor’s degree at Cornell*

recently called at the Section of Insects to obtain determinations for ants
and termites from Peru*

George H* Goss and family recently visited the Division of Insects to
see parts of the large collection made by H* D. Dodge and G. H. Goss in their
ascent of Mt# Kinabalu, North Borneo, in 1904. Shortly after their return
to this country, after the expedition, the first set of the collection of
insects v?as given to the Museum. The collection included very many interes-
ting forms, some oi which have already been described, and other await study
in connection with revisionary papers* On this expedition they collected a
new land shell V7hich Dr. Bartsch n^ed after Mr* Goss, and also collected
a new bird which Dr* Richmond named after Mr* Dodge*

Carl Heinrich returned to Washington on April 13, after a three
months* trip in Arizona* During’ this trip Mr* Heinricij assisted in scout-
ing work for the pink boll worm and Thurberia weevil in Arizona and New Mexico,
and spent some time V7ith Mr* Wildennuth in studying the southv7estern com
borer at Tempe, Ariz* Aside from the general scouting 'work on the corn borer,
Mr# Heinrich had, but little opportunity to collect specimens for the collec-
tion*

Dr# F*M#*Root, of Johns Hopkins School of Hygiene' and Public Health,
who has called on Dr* f^ar at the Division of Insects several times for de-
terminations of mosquitoes, recently left for a four months’ trip to Vene-
zuela, vrhere he expects to obtain more material*

-Dr* H* E. Ev’/ing returned on April 26 from a trip to tne Southwest
where he stopped at San Antonio and Dallas, Ten., Tucson and Tempe, nriz.,
and Tallulah, La, Tne floods in the lower Mississippi Valley- prevented the
collection of adults of chigger mites around Tallulah, hut the work in
Arizona and Texas was much more successftil, as a great numher of specimens
of scorpions v/ere collected, and a considerable number were brou^it home
alive for making observations on life histories and development, . a few
records of serious or fatal stings by scorpions were obtained, and some of
them were • carefully investigated*

G* H. Curran, of the Entomological Branch, Department of Agriculture,
Ottawa, Canada, spent tv70 'weeks in April in Viiashington studying flies in the
.national Collection, and collecting in the vicinity of the District# He
returned to Canada on April 29, Dhile here, besides consulting v/ith the

lected, and has arranged to have forwarded a considerable series of speci-
mens from India, He is primarily interested in completing his studies on
Bruchidae (Mylabridae) and is making an effort to find means- for continu-
ing them.

In the last v/eek of April the collection of insects which had been
formed by the Division of Truck Crop Insect Investigations v/as transferred
to the kuseiim, where it ?/ill be incorporated v/ith the regular collection.
This collection fopms an extremely valuable addition to the Museum, as it
gives a good series ; of* many- important economic pests, and associates in>-
mature stages v/ith adult-s. The specimens are connected vuth notes by
Bureau numbers under the Chittenden series •
