peers April 10, 1915. The main features of the report are indicated in the following para- 
Taphs: 
3 The establishment of the Insecticide and Fungicide Board renders it more than ever neces- 
sary that recommendations from bureau men concerning insecticides, their effects on insects, 
dilutions, etc., should be made with much conservatism. As is well known, the Insecticide 
Board is endeavoring to correct efficacy claims on labels of proprietary insecticides in strict 
accordance with well-determined facts. 
Greater adherence is desirable to the bureau policy of conservatism in giving information 
to correspondents, insecticide manufacturers, and others, relative to proprietary preparations. 
Inadvertent indorsements of such articles have, on several occasions, been used for advertising 
purposes. In general the name of a proprietary preparation should never be used in corre- 
spondence or in publications. In furnishing correspondents with names of firms manufactur- 
ing insecticidal preparations, such as arsenate of lead, lime-sulphur solution, etc., at least three 
firms should be cited. 
It is recognized that there is a distinct field for consecutive, thoroughgoing investigations 
of the general subject of insecticides. This work may best be accomplished if assigned to some 
one branch in the bureau, and the following division of work has been ordered: 
To the branch of Deciduous Fruit Insect Investigations has been assigned the general 
subject of insecticide investigations in the bureau. This branch shall also handle all corre- 
spondence relating to proprietary insecticides, or substances proposed as insecticides, which deals 
with requests for information not directly relating to the work coming within the domain of 
the respective branches. This office will also maintain as complete and up-to-date a bibliog- 
raphy of insecticides as is possible, and will keep a file of analyses of insecticides of all classes, 
and will endeavor, in all ways, to maintain as extensive a fund of information on the whole 
subject of insecticides as is possible. The collection of such information in one office will be of 
distinct advantage to the bureau in obviating, to a considerable extent, duplication in records, 
analyses, etc., since these records will be available for other offices in the bureau as needed. 
The branch of Deciduous Fruit Insect Investigations will soon be equipped with a laboratory 
for insecticide studies, and will inaugurate several lines of investigation in the general field, 
such as synthetic insecticides, insecticidal constituents of plants, etc. 
The different branches will continue, as heretofore, investigations of insecticides as is 
found necessary in connection with the work of their respective fields. It is advised that when 
it is found necessary to have analyses made of insecticides in connection with work in the various 
branches that requests for such analyses be made through the office of Deciduous Fruit Insect 
Investigations, to be transmitted by that office to the Bureau of Chemistry. This will insure 
that office in keeping its file of analyses up to date. 
Before undertaking detailed and special investigations of insecticides which have been found 
necessary in connection with their work, the respective branch chiefs shall submit to the Project 
Committee of the bureau an outline of the investigations proposed. Such action will tend to 
avoid duplication of work; to avoid ill-advised investigations, and may result in suggestions of 
value in connection with the execution of the investigation itself. 
In order to secure conservatism and uniformity in regard to insecticidal recommendations, 
manuscripts containing such recommendations should be submitted to the Project Committee 
for recommendation to the chief of the bureau before transmittal of manuscripts to the Division 
of Publications. [L. O. H.] 
BEE CULTURE. 
Dr. E. F, Puruurrs, In Charge. 
E. F. Phillips and George S. Demuth will attend the beekeepers’ conference to be held in 
Chattanooga, Tenn., April 27-29, in conjunction with the Southern Conference for Education 
and Industry, April 27-30. Dr. Phillips is chairman of this conference. _ ors 
George S. Demuth will go to Winchester, Va., early in May to continue investigations in 
conjunction with the Deciduous Fruit Insect Investigations on the effects on bees of spraying 
fruit trees. N. E. McIndoo went to Roswell, N. Mex., early in April on the same line of work 
and will also go to Colorado in May.
