visited, and also give the time employed or distance traveled and show rate charged therefor. 
If a special rate is provided for the service or trip, it should be so stated. A subvoucher in sup- 
port of hotel bills, paragraph 90 (A and 7) provides, must state the full period of service and the 
rate per day, week, or month. Often subvouchers are submitted for such claims wherein the 
day and hour of the beginning and ending of period are shown instead of the first and last item. 
(See p. 51 of the Fiscal Regulations.) Within the contemplation of the regulations govern- 
ing subsistence a day is divided into four equal parts, viz, breakfast, dinner, supper, and lodging. 
(See p. 52, Fiscal Regulations, which shows proper form of indicating price of each item, when 
period covered does not show uniform price of meals.) 
Paragraph 90 (p) of the Fiscal Regulations should receive the further attention of many of 
the field agents. This paragraph requires that the purchase of supplies in excess of $1.50 at 
one point on any one day must be supported by subvoucher or else it must be shown that 
different purchases making the total were made from different dealers. 
Storage charges (see par. 90 (0), Fiscal Regulations) and excess baggage (see par. 90 (s), 
Fiscal Regulations) often escape the notice of field men. 
All subvouchers must be correctly signed. The person receipting payment must show 
his full name and title. Initials are not sufficient to identify the payee. In case the payee 
can not write, he should make his mark in the presence of a witness, who signs his full name 
and address. 
The chief of the Bureau of Entomology is in receipt of a letter, dated April 24, from the 
disbursing officer of this department, wherein he advises that the Auditor for the State and 
Other Departments has agreed informally to pass accounts covering the purchase of drinking 
water for office purposes, incurred prior to May 1, 1915. Such charges thereafter will be con- 
sidered improper charges. 
Memorandum No. 128, dated March 31, 1915, amends the fiscal regulations. Men in the 
field should especially note the provisions (see paragraph 4 [c] and paragraph 28) which forbid 
the purchase of cameras and lances! Such must not be purchased now, unless specifically 
authorized by the Secretary. [O. F. Busby.] 
LIBRARY. 
The librarian reminds all members of the bureau of the desirability of the prompt use and 
return of books borrowed from the bureau library or from other governmental libraries in Wash- 
ington. This is necessary both for the convenience of our own staff and of others wishing to 
consult our library. If all books not personal property are kept together in one place in each 
office where they are readily accessible in case of urgent need by others, the annoyance of “‘lost 
books”’ will be greatly reduced. 
A goodly number of author’s separates have been added to the library during the past few 
months to the donors of which the library extends its thanks. Separates from nonentomo- 
_ logical journals and from publications not emanating from the Department of Agriculture are 
especially desired. [M. C.] :

INSECTICIDE WORK IN THE BUREAU OF ENTOMOLOGY. 
The bureau work with insecticides has, during recent years, become so large and varied 
that it has appeared desirable to systematize this class as much as possible. The whole subject 
was referred to the Bureau Project Committee, and its report was approved by Dr. Howard,
