GRASSHOPPERS (Acri&iidae) 
L. Haseman (March 18): Not threatening in Missouri. 
(Dispatch received from Fort. Worth, Texas, February 5 and pub- 
lished in The Star, Washington, D. C. ): Grasshoppers, which 
for the last, four years have eaten Up thousands of acres of 
cotton and grain and have even damaged trees in West Texas, have 
finally been eliminated by -the unprecedented cold weather of 
this winter- . From all sections come reports .'that the grass- 
hopper eggs have been killed by the 30-day freeze. 
Monthly Letter, Bureau of Entomology, No. 130 (February): C. H. 
Gable, of the San Antonio laboratory, conducted a scouting ex- 
pedition during the week of February 2 for the purpose of deter- 
mining the grasshopper situation in Brown and McCulloch Counties. 
He found that although reports; had been circulated to the effect 
that most of the eggs had ^een killed, more than 90 per cent of 
them were still in hatchable condition, and there were strong 
indications of serious trouble in that part of the State again 
this year. Later reports regarding the grasshopper situation 
in northern Texas are of a similar character.

A Summary of the Work Done by 'the Grasshopper Laboratories as 
Outlined at the Conference at Winnipeg, follows; 
Climatological Factors 
Observations of the following weather factors were taken hourly 
and sometimes half-hourly. These factors were temperature at 
four feet above the ground, relative humidity, barometric pres- 
sure-, sky, and wind velocity. The following results were ob- 
tained from averaging the number of grasshoppers feeding and the 
weather factors for each hour. It was utterly impossible to 
average wind velocity and clearness of sky because they are not 
given numerically. : : : "
