of Minnesota late in the summer, one of them passing into the northwest- 
ern cprner of Iowa. 
In Nebraska small local flights, going in different directions, were 
seen at Schuyler, and a small brood hatched out twenty miles west of 
Lincoln, while Omaha was, about the middle of June, visited by a few 
locusts from the south. 
In Indian Territory a swarm of considerable extent visited Fort Sill 
and deposited eggs, but nothing was heard from them the succeeding 
year. In Kansas, Dodge City was visited in September. There were 
also small local flights in Barton and Sumner Counties, Kansas. 
A larger number of flights from the northwest occurred in Dakota, 
extending from the neighborhood of Bismarck into Montana, and in 
June Bismarck was visited by a swarm from the southeast. 
While in Colorado the locust annually breeds in small numbers on 
the mountains, above an elevation of about 8,000 feet, only a few local 
flights were observed, viz, at Summit, in Estes Park, and at White 
River Agency ; also along the Upper Bear River Valley, where eggs 
were deposited. The progeny of the latter swarm went east the next 
summer (1879), passing over Denver and alighting a few miles to the 
southeast. A small swarm was observed going in a northwesterly course 
near Las Animas, on the Topeka, Atchison and Santa Fe Railroad. 
In Wyoming a large swarm at the end of July flew in an easterly 
direction over Como, and were supposed to have come from the Wind 
River and Bighorn region, while a few flew over Cheyenne. The north- 
western portion of the Territory was visited by swarms from the north- 
east which flew southwest. 
About Taos and Santa F<§, in New Mexico, as has already been stated, 
considerable local damage ensued and young hatched, but none were to 
be seen in the year succeeding. 
Utah, in 1878, was freer from locusts than in the year previous, but 
still the farmers in Summit County lost nearly half their wheat crop 
from the young, which hatched out in large numbers and, on becoming 
fledged, flew in a northerly course to Morgan County. Flights entered 
Malade and Cache Valleys late in August, arriving from Idaho, and 
locusts were seen at various points, late in July and during August, be- 
tween Franklin and the Montana line, near Pleasant Valley. The 
breeding-ground of these locusts was in Central Montana, as indicated 
on Map 3. In Montana, also, flights arrived in the central arable part 
of the Territory from the Yellowstone Valley on the east and from Brit- 
ish America on the north. (See also pages 7 and 8 of the present re- 
port.) 
PLIGHTS in 1879. 
The flights east of the Permanent Region were on the whole fewer this 
year than in 1878, as may be seen by an inspection of Map No. 4 ; though 
in Nebraska, Iowa, Minnesota, and Dakota there were more extensive
