Grasshoppers flying southeast in great numbers ; none lighted here. Those that 
JVvere here have all disappeared. 
For tha last mouth the 'hoppers have been flying every clear day when the wind 
vus northerly. One night they were flying in great numbers as long as we could see 
them and none fell down ; they were also flying the next day. Wo feel sure they flew 
-all that night, which was warm and without dew.

June 28, a considerable movement southeast, but none lighting heavily anywhere 
that I now recollect. 
July 1-8, heavy flights northwest, and considerable numbers lighting from Big Stone 
Lake northward, especially around Morris. ^ 
Since the 8th, particularly the 10th and 1 1th, heavy swarms flying south or a little 
■east of south, and considerable numbers lighting here and there as far east as Chaska, 
in Carver County. 
In general, they have heen flying every day with the wind, and as freely one way as 
another; no tendency to move in any particular direction. 
Locusts were passing Morris for nearly a week, some coming down, others rising, 
but when the wind was in from the north they all started southeast (or nearly south), 
and left Morris clean. When the northerly wind struck up there was a south move- 
ment (a heavy one, too) seen as far east as Big Lake, up in Sherburne County. As 
a great many have flown southwest across Rock and other south counties, I think 
it likely that many have gone off into Dakota that will not get back again. So far 
as I can see, the swarms have moved hither and thither, regardless of direction, wher- 
ever the wind carried them. 
Large numbers of dead locusts are being found everywhere. They are in the full 
grown and pupa states. In some cases, at least, it is due to the red mite.

July 1, 1877, at noon, 'hoppers in great numbers fill the air from 20 rods high to just 
as high as the eye can see them ; seem to be going southwest, as the wind is northeast; 
the flight at all times just the way the wind blows ; the weather is very warm ; the 
upper current of air is very mild; 'hoppers moving very slow, while the lower current 
is a little stiffer, and consequently the lower 'hoppers are moving much faster thau 
the higher ones. 'Hoppers hatched much most numerously this year (1877) the last 
of May; in 1875 nearly the same time. I think there was not more than one out of 
every thousand of eggs deposited here but what hatched. They were deposited in 
breaking most numerously, and very many on the raw prairie. They like hard, com- 
pact soil to deposit their eggs in best. The first insect acquired full wings about the 
■20th of June, 1877. Some were seen rising up and going off the 24th of June. 
Coal tar and sheet iron have been used very extensively, and other devices, such as 
"sacks and burning of straw and of the prairie grasses — all to no avail. 
We have had the 'hoppers with us since 1874, when they lit down on us, deposited 
their eggs, and in 1875 they hatched out. There was no emigration here that year. 
In 1876 they lit down upon us again, deposited their eggs, and from those eggs we 
have 'hoppers this year (1877).

Excelsior, Hennepin County, July 8, 1877. 
Wind has been from the southeast for a week till to-day. 'Hoppers were flying 
to-day from 11 a. m. till 3 p. m., with the wind from northwest; did not see any 
alight ; must have been a swarm rising from a whole district which passed wholly 
over. 
Ours are yet of all sizes; some still hatching; crops all uninjured, but the larger 
ones are beginning to climb on the wheat ears ; suppose you have heard of their mov- 
ing to the northwest these few days past.

BURNHAMVILLE, TODD COUNTY, August 24, 1877. 
The young insects generally traveled in the direction of the wind, but when once 
on their way, a change in the direction of the wind would not induce them to change 
their course. They also liked to follow roads and paths. They seemed to be more 
inclined to travel shortly before they enter the winged state than at any other period 
of their development.
