done, and in Cass Co., Nebraska the crops are very heavy.” — N. Y. Sera. Tribune, July

“ Omaha , Nebraska, July 16, 1867. — The Grasshoppers have not done as much damage 
in this State as was expected. Their ravages are most extensive along the Huerlano 
and Arkansas.” — Prairie Farmer , July 20th, 1867. 
“ Ottawa , Kansas, July 22, 1867. — The Grasshoppers, what was left of them —per¬ 
haps one for every fifty that we had last autumn —staid here till their wings attained . 
full size, and then got up and left. The damage they have done to this part of the 
country amounts to nothing. I am told that in some of the counties north of us they 
destroyed a little grain before they left T. K.” in Prairie Farmer Aug. 3, 
1867. 
“ Nebraska City, Nebraska, July, 1867. — The season has been cold and backward, yet 
favorable for small grains, until the Grasshoppers hatched and commenced depredations 
upon our wheat, which has suffered tremendously. Many fields will not be worth 
cutting. Some fields of corn are badly thinned. Potatoes in some places are com¬ 
pletely stripped, and our gardens are eaten through and through.” — Monthly Pep. Agr. 
Pep., 1867, pp. 244-5. 
“ Piehardson Co., Nebraska, July, 1867. - The Grasshoppers have destroyed nearly all 
the crops in this county, and are still at work.” Ibid., p. 245. 
“ Douglas Co., Kansas, July, 1867. —The Grasshoppers have been doing much damage 
in this vicinity, to all kinds of vegetation.” Ibid., p. 245.

account.” — “ A. G. B.fi in Prairie Farmer Aug. 10, 1867. 
The migratory propensity is developed, from time to time, in the mature or winged 
Hateful Grasshopper in its native alpine home, whenever it has increased in numbers 
so greatly as to become instinctively aware that, if it deposits its eggs in the same 
district in which it was itself raised, its future offspring will starve. In the immature oi 
wingless Hateful Grasshopper, so long as it remains in a healthy state and finds plenty of suita¬ 
ble food athand, no such propensity would, I think, ever be developed, because it has not 
yet arrived at the time of life, when the feelings connected with the reproduction of 
the species are called into play. Hence the fact, so often set forth in the .preceding 
extracts, as well as elsewhere, namely, that the larvse of those Grasshoppers, which had 
hatched out in the lowlands, in the spring of 1867, had already shown a premature pro¬ 
pensity for migration, though they had plenty of good food at hand, seems to prove 
that they were in a diseased and unnatural condition. I feel confident, at all events, 
that no healthy grasshopper-larvse would ever pass straight through a field ol gieen 
grain, without stopping some considerable time to take toll of it, as is reported above 
by the Leavenworth Tribune. (Page 87. ) Hence, I infer that the whole brood of 
Hateful Grasshoppers, both young and old, throughout Kansas, Nebraska and Missouri, 
were, in the spring and summer of 1867, in a more or less diseased and abnoimal state, 
in consequence of the great change in the “ Conditions of Life” previously referred to. 
(Page 83.) This accounts for the fact that, comparatively, so little damage was done 
by them, when we take into consideration the enormous numbers that hatched out. 
Likely enough, a very large proportion of them died a natural death, befoie they 
arrived at years of discretion, as indicated in some of the above reports, and in others 
that will be given hereafter.
