Oregon Short Line were visited. Huntington, Oreg., which is rather 
outside of the farming district of the State, and Pendleton, in the center 
of the farming district, were then visited. A stop of some days was 
made at this point because of the reports received regarding damage 
done to wheat in this vicinity, on the Columbia plateau, in this and 
preceding years. 
Only Walla Walla and Spokane Falls, in Washington, and two places 
in Montana, were visited. This resulted as much from being reason- 
ably certain that this region was exempt from injury as from lack of 
time. On my return, stops were made at Sheridan, Wyo.; Edgemont 
and Deadwood, 8. Dak., and at various points between Chadron and 
Lincoln. 
After returning to Lincoln, numerous short trips were taken to differ- 
ent points in the State. Beatrice, 'airbury, 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 (Melanoplus 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, Wyo., 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 the south and 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 
definiteness as well as for convenience, | have so divided the subject. 
The summary at the close will, | hope, remove unintended impressions 
resulting from this method. 
NEBRASKA. 
The Rocky Mountain locust (Melanoplus spretus), 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
