federal agricultural service, and all of the problems connected with such an organ- 
ization are under careful investigation. The different colonies in Australia have 
leveloped strong departments of agriculture with an entomological service in each 
‘one. The old problem of "States’ Rights" is naturally more confusing out there 
‘with the new Federation than it is in the United States or even in South Africa. 
In the latter case there has been not simply a federation, but a much more cent- 
ralized organization. 
WAR LIBRARY SERVICE 
q The returns from the March drive of the American Library Association for 
books for the camp libraries have not yet been fully tabulated but as far as 
made indicate a most generous response on the part of our people. Since the 
drive more than a thousand volumes have been brought in to tae Library of the 
Department of Agriculture alone. This is a splendid beginning but the camp 
libraries'needs are continuous and will be until the war ends, Therefore bring 
in as many more books as you can spare from your shelves for all can be used, 
Letters in the library journals from the men in charge of these libraries show 
how very much the bonks are appreciated by the soldiers and sailors, 
{NFORMATION KELATIVE TO INSECTS DESIRED, 
: The compiler of the Monthly Letter of the Bureau will greatly appreciate 
it if members of the Bureau force will furnish him with citations wherein insects 
have been used as the basis of fiction. Many such contributions to fiction have 
been published in the past, some good, but for the most part indifferent or wholly 
unworthy. The following features are desired: Title of article, autnor, and year 
of publication: If pub!ished in a magazine, give name, month, and year of maga- 
gine. (B. A. Reynolds.) 
HESSIAN FLY AND PARASITE TRAP CAGES FOR FIELD USE, 
f Last year certain of our Hessian fly experiments necessitated the determina- 
tion of emergence of Hessian flies and parasites from known areas and for this pur- 
pose light proof boxes, consisting of simple frames covered with roofing parer 
answered the purpose satisfactorily, To these it was proposed to attach a para- 
site trap such as has heretofore been used for similar purposes. A trap was de- 
 gigned as follows: The trap proper was @ cylinder about 2 + inches in diameter 
and 4 inches long and made of celluloid held in place by a framework of tin. 
The ends were covered with a fine cheesecloth. A hole was made in the side and 
a 20mm, glass tube inserted and the outer projecting edge of the tube inserted 
in the roofing paper cage. This answered very satisfactorily, but the cage was 
rather difficult to make and further the opening of the glass tube so large many 
of the flies and prasites probably returned to the darkened cage. 
| At the Hessian fly conference in Washington last winter Mr. Creel suggested 
a tin trap which consisted of a cylinder of tin in which was soldered a cone of tin 
with an opening at the tip of cone, This is inserted in the cage and @ glass vial 
‘fitted into the cylinder of tin. This was a simple affair and seemed satisfactory 
except that the small opening permitted only a gmall ray of light to enter the dark 
ened cage which seemed possibly insuffic.ent to readily attract the insects into the 
trap. Accordingiy we designed another simple trap which enables us to secure a
