as to whiten the surface wherever the ground was ploughed and they 

 were exposed to the bleaching and cleansing effects of sun and rain. 

 All the reports agree that low and moist ground was avoided. 



8 — In most counties, even in the northern ones, some of the ear- 

 lier eggs hatched, especially those laid on hill-sides and other high 

 ground exposed to the rays of the sun. The young hoppers attained 

 a size of :^ to ^ of an inch, and were active during the middle of the 

 day, even into December. These young hoppers disappear and seek 

 Winter shelter; but it is doubtful whether many, if any, survive the 

 Winter. 



9 — From the accounts received in answer to this question, it ap- 

 pears that in 1866 the locusts invaded pretty much the same counties, 

 the farthest point reached to the eastward being the western portion 

 of Benton county. As the map indicates, they reached somewhat 

 further east in the northern part of the State than in 1871, but not so 

 far in the southern counties, there being none recorded in Polk and 

 Lawrence. Yet imaginary lines, indicating the average eastern limits 

 of their advance in either year would run a little to the east of War- 

 rensburg and Clinton in Johnson and Henry counties, and not more 

 than a dozen miles apart. They came a month later in 1873 than in 

 1874, and were moving from about the first of September to the end 

 of October. The direction of their flight and progress was precisely 

 as the past year, i. e., from the northwest. They deposited large num- 

 bers of eggs which — for the most part — hatched in the Spring of 1867. 

 The young hoppers did much damage in many localities in the Spring 

 of this year, destroying the wheat, corn, grasses and vegetables by 

 stripping off the leaves and leaving only the bare stalk standing. 

 They also attacked the oats, biting the stalks and causing the grain 

 to drop. They fed in large bodies, traveling together, and thus devas- 

 tating the crops in strips and sections, leaving the intermediate fields 

 untouched. But taking the reports of all the counties, comparatively 

 little damage was done by these young hoppers — much less than was 

 anticipated and seemingly warranted by the large numbers which 

 hatched. They were attacked by parasites and diminished rapidly in 

 numbers ; and those which acquired wings, in the early part of July, 

 generally left their place of birth, flying in all directions, but princi- 

 pally in the opposite direction to that in which they had come the 

 previous Fall. They laid no eggs and were gradually lost sight of the 

 latter part of the growing season. 



10 — The insects came too late last year to do very great injury. 

 Everything green had about disappeared on account of the continued 

 drouth and Chinch Bug. Wheat had been harvested and was there-
