C. L. Corkins (July .20)': The only* new -development in the 
grasshopper situation in Wyoming is the extension of the out- 
break into the lower North Platte Paver Valley, particularly 
Goshen County. 
C. P. Gillette (July 22): Grasshoppers are very abundant 
generally in the eastern Colorado plains. To date the Experiment 
Station has put out poison enough to treat 200,000 acres with 
arsenic-bran mash. 
C. Wakeland (July 23): Grasshoppers, numerous species, are 
very destructive to farmers in some of the higher mountain valleys 
in northern Idaho, where control is difficult because of the large 
proportion's of. range land adjacent. Grasshoppers are causing 
serious injury to irrigated crops in many sections of southern

individuals and small-scale organizations in control.

kills were made in the Port Klamath, Upper Klamath, marsh at 
head of the Williamson River, Sprague River, Sycan, raid Upper
