MINNESOTA. 



NorseJand, Nicollet Couniy. — 26. Invading swarms have not injured the native grasses, 

 but the young injure it greatly ; from one-third to one-fourth is devoured by them. 

 27. Have observed none but tame chickens feeding on insects and eggs. 28. No meas- 

 ures for destroying the eggs have been tried in this section. 29. County consists of 

 one-fourth timber and three-fourths prairie. Township all prairie, with only one- 

 fourth mile to timber on the east, from two to three miles on the south, and a small 

 grove just north of it. 30. At night both the young and grown insects sit still. If 

 they are near any fence, growths, or anything elevated from the ground, they will 

 crawl upon it. If they are on bare ground, they will go in clusters to remain over- 

 night. 31. Depends upon the force of the wind; probably 10 to 15 miles per hour. — 

 [Webster. 



Dewald, Nobles County. — 23. Do not hatch here in the fall to any great extent. 24 

 and 25. Pease and horse-radish are the only cultivated plants I am acquainted with that 

 ihey won't eat, and among the wild the cockleburr, purslane, and helianthus seem to 

 be exempt. When they can, they eat oats, flax, corn, wheat, and potatoes in this order. 

 29. No timber in this part of the State, excepting young plantations two to four years 

 old. 30. Do not eat nor fly, roost on the fences, or get under clods of dirt, &c. 31. 

 Kate of speed depends on the force of the wind. — [Bates. 



NEBRASKA. 



Farmers Valley, Hamilton County. — 23. In the faU of 1874, the county was surprised 

 to see numbers of small 'hoppers. 24. Wild buckwheat, onions, cabbage, carrots, 

 beans, asparagus, parsnips, &c. ; 1874, corn nearest maturity ; 1876, earliest corn ; their 

 taste seems to differ with the times. 25. Pease. 26. Never been any injury done here. 

 27. Birds, snakes, frogs, toads eat insects ; birds eat the eggs. 28. Harrowing. 29. 

 Twenty-nine-thirtieths prairie, one-thirtieth timber. 30. At night and in rainy weather 

 they go to high grass or stalks for shelter. I had a field of corn in 1874 that was stand- 

 ing and not seriously damaged when night commenced. The next mrrningit was only 

 corn-stalks, leaves and ears having been eaten. [J. Yosburgh.] 23. A very few hatched 

 in Fall of 1876. 24. Corn, timothy, clover, onions, potatoes, beans, turnips, petunias, 

 foliage of fruit trees, willows, poplars. 25. Chufa, tomato, phlox, pansy, Madeira 

 vine. 27. Harpalus Pennsylvanicus and a dipterous larva; red bug destroying eggs. 



29. No timber except narrow belts along streams. — [G. M. Dodge. 



Plattsmoulh, Cass County. — 24. Cabbage, turnips, and wheat invariably ; others vary. 

 My neighbor on an adjoining lot had his lettuce and pease entirely destroyed, while his 

 other plants are untouched. In mine nearly all are gone but lettuce and pease, which 

 are unharmed. 27. Hogs and birds. 28. About four-fifths prairie in Cass County. 



30. The young cluster under leaves, clods, roots, &c., not at night, but in rain and 

 cold weather ; do not eat under such circumstances. The grown remain perched on 

 trees, bushes, &c. When on the wing I am much inclined to think they fly all night. 



31. Movements regulated by the wind. — [Child. 



Sunlight, Cass County.— 23. Never known any to hatch. 24. Eadishes, cabbage, 

 onions, tansy, rhubarb, wild and tame buckwheat. 25. Pease, tomatoes, sweet and
