in the valleys and foot-hills wherever water stood in pools, and after 

 they had feet began spreading over the country. These will, if they 

 winter favorably and come out again in spring, of themselves be nearly 

 sufiQcient to clear away a moderately extensive grasshopper plague. 



Should the inhabitants then lend a hand and assist these natural 

 enemies in their efforts to check the plague, the summer of 1891 will 

 end the grasshopper plague in that part of the State at least. 



Leaving Soldier we were driven 30 miles into Haley by W. T. Perkins, 

 who was untiring in his efforts to aid us in securing all the knowledge 

 available concerning the locusts in the prairie and surrounding country. 

 From Haley we proceeded by rail to Shoshone and Boise City. At this 

 latter point collections were made of the different locusts that were to 

 be met with. Here the short- winged form of Melanoplusffavo-annulatus 

 Thos., known as Pezotettix enigma Scudd., was taken in large numbers ; 

 in fact it was so common at one point that it had become a nuisance, if 

 not a pest. But, as the species prefers open country to the cultivated 

 fields and low meadows, it may never prove injurious to crops. Aside 

 from this hopper several other locusts were also present in larger num- 

 bers than usual in the foot-hills back of town. None of the Gamnula 

 pellucida were found or reported within less than 25 or 30 miles to the 

 eastward. 



Aside from these insects it was noticed that the codling moth and the 

 apple tree aphis hold almost complete sway in the beautiful orchards 

 with which the region abounds. Almost every apple and pear is punct- 

 ured by the larvse of the former, while the latter cover nearly every 

 apple-tree in the city, and what is to be most regretted is that noth- 

 ing is done to check these enemies. Thousands of bushels of valuable 

 fruit fall to the ground and are permitted to lie there and rot and propo- 

 gate the future broods of the worm. None of the " wind-falls" are gath- 

 ered and fed to hogs or even dumped into the river. 



From Boise City we returned to Pocatello, where we took train for 

 Beaver Canon, one of the points to be visited as indicated in the letter 

 of instructions. Arriving at this latter place, we soon learned that 

 locusts were not present in more than ordinary numbers either here or 

 across the divide in the vicinity of Eed Rock and Henry's Lakes. This 

 we learned from a rancher and guide to Yellowstone National Park who 

 makes his headquarters at Henry's Lake. He said the 'hoppers were 

 not at all common about either lake, in fact hardly plentiful enough for 

 fish-bait. After spending a day here we went south to (Jgden and Salt 

 Lake City, at both of which puints collections were made. 



Upon inquiry among the railroad men who pass through there, it was 

 not thought necessary to proceed to Nephi, the seat of last year's grass- 

 hopper injuries. We accordingly started for home, stopping over one 

 train at Cheyenne, Wyo. While here we were informed that there were 

 a great many grasshoppers along the line of the Cheyenne and Northern, 

 a branch of the Union Pacific Railroad. These locusts our informant
