Oregon Short Line were visited. Kuntin^iiton, Orep:., wliic.li is ratlier 
out:-i(U' ol the tarnnn«; district ot the State, and Pendleton, in tlie (MMitcr 
of tlie t'arininj»: district, were then visited. A stop of some days was 
made at tliis point becanse of the rei)orts received re«iardinf4- (hinnige 
done to wheat in tiiis vicinity, on the Cohunbia phitcan, in tliis and 
])recedin.<i- years. 
Only Walhi Walhi and Spokane T'alls, in Washinj^ton, and two phices 
in Montana, were visited. This resnlted as niucli from beinj>' reason- 
ably certain that tliis region was exeni])t from injnry as from lack of 
time. On my return, stops were made at Sheridan, Wyo.; l^idgemont 
and Deadwood, S. J3ak., and at various points between Ohadron and 
Lincoln. 
After returning to Lincoln, numerous short trips were taken to differ- 
ent points in the State. Beatrice, Fairbury, Geneva, Columbus, Omaha, 
and Fremont were visited at this time. 
The plan pursued was — 
First. To visit personally as many districts as possible where known 
to be infested. 
Second. To pass through and along the limits of the permanent 
breeding region, making short excursions within to ascertain the status 
of the Rocky Mountain locust [Melanoplua spretus) which, at the time of 
beginning this work, appeared to be in a condition of general awak- 
ening. 
Besides the information gathered on this trip of investigation, I have 
used, in making this report, observations made and material collected 
on a trip through the northern and western part of Nebraska and east- 
ern Wyoming in the interest of the Nebraska Experiment Station, dur- 
ing June; also a trip from Lincoln to Salt Lake City, on which many 
stops were made, in July; and on a trip to the Big Horn Mountains, 
40 miles west of Sheridan, AVyo., also in July. These trips — one to the 
heart of the permanent region in Wyoming, another one completely 
through this region, 500 miles farther south, with the trip through Col- 
orado to tlie south aiul Montana to the north — completed a reasonably 
exhaustive survey of the regions liable to injury and of the sources 
from which injury, if it is done next season, will spring. 
Although the discussion of this question may not, in the nature of 
the case, be readily divided by States, yet, in the furtherance of 
detiniteness as well as for convenience, 1 have so divided the subject. 
The summary at the close will, I hope, remove unintended impressions 
resulting from this method. 
NEBRASKA. 
The Ivocky Mountain locust (Melanoplus spretns), hatched in the 
early part of April in this State along the Niobrara Valley, from Sioux 
County on the west eastwards nearly 200 miles to the vicinity of Bas- 
sett, and in the valley of the North Platte from the west boundary of
