“Wheat, so long the leading crop of the State, has hardly lost 
its prestige. * * * The ravages of its enemy, the chinch bug 
(Micropus leucopterus of Say), were extensive in 1864, 1865, and 
1866, but the extremely cold winters that succeeded, or other nat¬ 
ural causes, have nearly exterminated it.”

chinch bug, are, I believe, rejected by all.”
