EITHER YOU ARH FOR THE UNITED STATES -- oR you ARE AGAINST IT! THERE CAN BE 
“NO MIDDLE ROAD! ‘TO DO, WHOLE-HEARTEDLY, THE TASK WHICH THE FORTUNES OF WAR 
“AND YOUR COUNTRY HAVE SET BEFORE YOU, IS THE GREATEST SERVICE TO YOUR COUNTRY! 
“HISTORY MAY NOT ALLOT TO YOU A PLACE IN THE HAL, OF FAME! THE PLAUDITS OF A 
GRATHFUL COUNTRY MAY NOT ACCLAIM AND GROWN YoUR EFFORTS! BUT IN THE END YOU 
“MAY REST IN THE REALIZATION - THAT YOU HAVE DONE YOUR WHOLE DUTY - AND AFTER 
ALL -~- WHAT MORE HAS LIFE TO OFFER? WHAT WOULD It BENIFIT A MAN OR HIS CHIL- 
DREN, THEN- IF HE GAIN THE WHOLE WORLD - AND GO DOWN TO HIS GRAVE - A SLACKER? 
ADDITIONAL NOTE ON THE EFFECT OF THE COLD WINTER UPON PRINCIPAL 
. CROP INSECTS. 
In the January Letter I asked for observations during the coming season 
as to the effect of the extraordinary winter on the principal insect enemies 
of the important crops. 
Dr Henry Fox calls my attention to the danger of misinterpretation as 
to cause cf lessened numbers of such pests, showing that in his work certain 
grouse-locusts which past the winter in the adult stage are scarce at Clarks- 
ville, Tenn., where they were very common’ las+ spring. It would be fair, withe 
out other knowledge, to attribute their present scarcity to the severe cold of 
»the present winter, but he happens to know that they were just about as scarce 
tast fall as they are now, and thinks that the reason was a long period of very 
dry weather in the early fall which came at a time when the eggs should have 
been hatching and the: young beginning their development. So it will be well in 
submitting observations to consider possible explanations cther. than the extra- 
ordinary cold of December and January. (L.0.H.) 
VISTOR TO THE BUREAU IN FEBRUARY. 
Mr. P. van der’ Goot, of Buitenzorg, Java, Entomological Assistant at 
“the great sugar experiment station there, wes in Washington from the 15%th to 
‘the 25th of February, looking up matters connected with the injurious insects 
of tropical crops. Mr. van der Goot is especially well known by his writings, 
his large contribution to the knowledge of Aphididadé of Jdva and other papers 
of importance. He speaks English very fluently, and is still a young man with 
my years of work ahead of him. He is on his return to Java from Holland, 
and will stop, in crossing -this country, at New Orleans, at Tucson, and at 
Pasadena, and hopes to spend ten days in Hawaii. (L. 0. H.) 
WAR LIBRARY SERVICE 
The response of the people of the United Stdtes td the request of the 
American Library Association for books for the camp libraries has been most 
Generous. Hach of the 32 cantonment libraries now has a library building con- 
aining from 10000 to 15000 books and accomodating from 175 to 200 readers. 
ese are also at each large camp from 8 to 20 branch stations containing from 
00 to 1500 books and several deposit stations. The call still comes for books 
1f a million
