Cosmos, Meeker County. — For destroying the winged, a line has been dragged across 

 the field by two nien, thus disturbing the 'hoppers so that they sometimes leave. 

 Sheet-iron pans, with coal-tar in them, have been used for destroying the young. — [Mc- 

 Donald. 



Mankato, Blue Earth County. — Ditching very successful. 'Hopper-dozers with coal-

 a strip of board about 2 inches wide and 3 feet long. — [Howard. 



Albert Lea, Freehorn County .—BvLvning aud tar-dozers. — [Johnson. 



Burnhamville, Todd County. — For the young, coal-tar has been used with some success 

 when the grain is not over 6 to 8 inches high. Ditching has been made use of only in 

 isolated cases, but is the most effective remedy. — [Rhoda.

 light cloth attached to the rear pan to prevent them from hopping over the pans. — 

 [Cross. 



Madelia, Watonwan County. — 1st. Tar pans. 2d. A machine mounted on wheels with 

 reel in front, with pan of coal-tar. This runs in front of team, and when vegetation 

 is too high the reel can be removed, and by pushing it rapidly against the grass after 

 the 'hoppers have gone to roost, they very readily fall into the tar. — [Sylvester.

Norseland, Nicollet County. — Burning coal-oil smeared on large sheet-iron plates ; no 

 great benefit. A board fence two feet high, perfectly tight, with a three-inch batten 

 nailed to the top so that the batten is on the outside of the field. The edge of this 

 smeared with coal-oil three or four times a day. When the 'hoppers come to the fence 

 they will march up until they come to the batten, when smelling the coal-oil they will 

 either retreat or jtimp and fall back on the ground ready for another trial ; finally they 

 will coinmence to march in one direction alongside the fence, where an occasional pit 

 is ready to receive them ; and by accumulating in these pits they will die of them- 

 selves. Thirty bushels have been caught in one pit. Very successful. Winged : Large 

 bag attached to wheels, with another sack to empty them out through.— [Webster.

 ones. — [Tiffany.
