MEANS OF DESTEUOTION. 



[Answers to the following questions in Circular No. 1: 16. The means employed in 

 your section for the destruction of the unfledged insects, or to protect crops from 

 their ravages, and how far these have proved satisfactory. 17. The means employed 

 in your section for the destruction of the winged insects, or to protect crops from 

 their ravages, and how far these have proved satisfactory. 18. Descriptions, and, if 

 possible, figures of such mechanical contrivances as have proved useful in your 

 locality for the destruction of either the young or the winged insects.] 



DAKOTA. 



Olivet, Hutchinson County.— Smoking has been tried with varied success. They were 

 kept off of small gardens and patches by driving.— [Jones. 



Sioux Falls, Minnehaha County. — Burning prairie-grass, which does but little good, 

 owing to the fact that so many renaain in grain.— [Newton Clark. 



Madison, Lake County.— Smoking, which did very little good. — [Law. 



Sioux Falls, Minnehaha County. — Sheet-iron pan, 8 or 10 feet long, with a back 1 foot 

 high ; bottom covered with kerosene oil. Burning prairies. This is objected to, how- 

 ever, on account of its destroying too many birds' eggs and young and unfledged 

 birds. During a rain the locusts on a large piece of last year's breaking crawled under 

 clods of earth for protection. As soon as practicable the ground was rolled with a 

 heavy roller and the entire number exterminated. — [Everett. 



Wahpeton, Bichland County. — The sheet-iron 'hopper-dozer, a strip of sheet-iron 12 or 

 14 feet long, turned up at the back and ends 6 or 8 inches, in front one inch; pan 

 covered with tar, kerosene, soft soap, &c. ; whole drawn by wires or cords. — [Smith. 



Milltoivn, Armstrong County. — Kerosene oil. — [Taylor. 



Saylroolc, Clay County. — The tin pan and kerosene oil ; burning hay, straw, &c. — 

 [Hall. 



Sioux Falls Post-Office, Lincoln County. — Nets were used, but the outlay of labor ex- 

 ceeded the benefit derived from them. — [Jacobs. 



NEBRASKA. 



Burr Oali, Otoe County. — Crushing with heavy rollers, burning prairie-grass and win- 

 nows of straw, were means used for destruction of unfledged locusts. — I Davidson. 



Fremont, Dodge County. — Sheet-iron pan, 3 to 7 feet long, something in the shape of a 

 road-scraper (the sides being higher). The back part of the bottom is dropped in the 

 shape of a pan 3 inches deep and 1 foot wide, nearly filled with water, which is covered 

 with kerosene oil. The oil kills the 'hoppers, and they sink into the water. The larg- 

 est pans are without wheels, and are drawn by two men; the short ones are on trucks, 

 and are pushed. Some are made with wire-cloth covers, hung with hinges, so that 

 when the motion stops, the top will drop and secure the 'hoppers.— [Blanchard. 



Glencoe, Dodge County. — Burning and x^lowing under for the young.— [Dodge. 



Amazon, Franlclin County. — Burning the unfledged by scattering straw and firing the 

 prairie grass. — [Hendricks. 



Grand Lsland, Hall County. — Canfield Grasshopper Exterminator, with coal-oil for the 

 unfledged. — [Stolleyc 



Salem, Bichardson County. — Unfledged: Principally sheet-iron pan, 8 feet long, 2 feet 

 wide, edges turned up in front 1 inch, 3 inches on back ; back 20 inches high ; muslin, 

 well saturated with coal-oil placed in bottom ; drawn by two boys or men. » * * 

 With better success, a box 12 to 14 feet long, bottom 4 inches wide, made out of 1-inch 

 lumber; top, with space between, for 'hoppers to jump into ; wire screen and box be- 

 hind for their reception. The locusts remain until the box is filled. Ten bushels per 

 day have been captured by this machine. Burning, ditching, &e., have also been 

 resorted to. — [Lincoln. 



Tecumseh, Johnson County. — Coal-tar, kerosene, and nets ; ditching and plowing also 

 very Satisfactory. The nets and i^latforms for tar were built on runners, and drawn 

 by horses. — [Holmes. 



Hooper, Dodge County. — By burning straw, plowing the eggs Under deep on cultivated 

 soil, by various traps and machines, and, above all, by protecting the birds. The es- 

 sential features of the machines used are : 1st. A platform that runs on the ground on 

 runners or wheels. 2d. A canopy, meeting platform at an angle. 3d. A reservoir at
