ny evidence of the pink bollworm. Neither was any evidence of infestation found in 
he district opposite Eagle Pass, Tex., but two Mexican plantations near the United 
ates wore found on which considerable areas of cotton had been planted with seeds 
mported from the Laguna district. There is every reason to anticipate, therefore, 
hat in these fields the pink bollworm will develop this year. A very strict watch 
ust be maintained, and whatever remedial steps pessible will be undertaken in 
cooperation with the Mexican authorities, 
J. A. Dew made a visit to Washington, and more recently E. R. Sasscer has 
roceeded to the Texas border to advise the inspectors of the Board as to methods 
fumigation of cars and freight. 
| E, R. Sasscer has recently completed a new series of tests with baled Egypt- 
ian cotton to add to the duta already obtained as to the efficiency of fumigation 
nethods. As a result of these experiments, the Board will recommend that the period 
pf fumigation of imported cotton be extended to two hours instead of one hour and 
orty-five minutes. With this fumigatioca period it is believed it will be entirely 
safe to eliminate the screening requirement hitherto made of all mills vsing import- 
3d cotton and of all storage places for such cotton. 
FOREST ENTOMOLOGY. 
A, D. Hopkins, Entomologist In Charge. 
After spending a week at Washington Dr. Hopkins returned to Kanawha Station, 
. Va., Field Station on June 6, to continue his studies on the relation of climate 
%o the periodical phenomena of insects and to entomological problems; insects affect- 
ing shade trees and hardy shrubs; hickory insects, and insects injurious to forest 
products. 
; Dr. Boving and F. C. Craighead left on June 20 for a field trip to Harrisburg, 
Pa., and vicinity, where they will make observations on insects injurious to forest 
trees, especially Cerambycid and coleopterous larvae. A. B. Champlain expects to 
join them on the 25tn. 
S, A. Rohwer will go to Philadelphia on the 25th to study the types of 
Gresson’s species of Lissonotini and certain other parasitic hymenoptera and 
also to examine come of Norton's types of sawflies. 
W. 8. Fisher left the early part of June for a field trip to Harrisburg, Paey 
and vicinity, to make further observations and studies of the hickory barkbeetle.
