Dr. Shimer in his Notes on the chinch bug, sa3s that itattained the maximum of its development in the summer of1864, in the extensive wheat and corn fields of the valley of theMississippi; and in that single year three-fourths of the wheatand one-half of the corn crop were destroj^ed throughout manyextensive districts, comprising almost the entire North-west,with an estimated loss of more than one hundred millions ofdollars in the currency that then prevailed, Avhile Mr. Walshestimates the loss, from the ravages of this insect in Illinoisalone, in 1850, to have been four millions of dollars.
