The other section in which the locusts are doing damage, as before 
described, lies in the eastern part of the State, in the mountains, and 
not contiguous to the plains as in the Boise Valley. 
This region being far from the railroad, about 75 miles from the 
nearest point, I was unable to visit it, but was fortunate to meet a very 
intelligent gentleman, Mr. Alex. Burnett, of Antelope, in the Lost 
River Valley, who gave me very valuable information regarding the 
locust visitation in that region. 
In the summer of 1891 the locusts came into the Big Lost River Val- 
ley by flight, coming chiefly from the southwest, presumably from the 
Camas prairie country to the west of Wood River. They laid eggs. 
quite abundantly, both in 1891 and in 1892, so that they are completely 
denuding the farms in many parts of the valley from Areo to Huston. 
They have not yet acquired their full growth, but if they deposit eggs 
as generally as in the two past years, they will eat everything up in the 
entire valley. The kind is not determined, but Mr. Burnett will send 
specimens of the insects so that the species may be determined. They 
are presumed to be Camnula pellucida from description. 
In neither locality has any effort been made to combat the destructive 
tendencies of the locusts, all trusting to natural causes to reduce the 
numbers as in the past. It will be interesting to note the condition in 
another season, when more time with better facilities for study and 
observation will be at my disposal for the purpose. 
The people of Idaho give little attention to the locusts, as they are to 
a great extent local and much restricted in their ravages, but the Great 
Plains cricket, Anabrus simplex, is causing a good deal of consternation 
over quite an area of the middle portion of the Great Snake River 
Plains and the mountain region to the north, chiefly along Wood River 
and its tributary valleys. 
Wood River is the only stream from Henrys Fork which takes its rise 
in Yellowstone National Park to find its way across the great lava 
plain of the Snake to that river, the others losing themselves in the 
lava beds to emerge as immense springs in the great canyon of the 
Snake. Wood River takes its rise in the great central plateau of 
Idaho and has a course nearly south of about 100 miles, and with its. 
tributaries furnishes some of the finest agricultural lands in the coun- 
try, aS well as an immense area of the best mountain grazing lands in 
the northwest. Any disaster to the crops of this region will of course 
be a great misfortune. 
The northern boundary of the plains of Snake River consists of an 
irregular crescent-shaped series of hills or low mountains, the outposts 
of the higher mountains lying to the north, and becoming so celebrated 
for their rich mines of gold and other metals. 
In these foothills, along Wood River and for a distance of 50 to 60 miles. 
to the westward, is where the crickets have this year become so numer- 
ous as to do a great deal of damage. They have been known to exist
