country, and the Legislature voted one hundred thousand dollars to carry on the war. During 1892 and 1893 the committee in charge of the work asked for much more than they received. In 1894 one hundred thousand was again voted. Then it was considered of national importance, and Congress was petitioned to come to the aid from the National Treasury, and forty thou-sand dollars was voted. In 1895 Massachusetts voted one hundred and fifty thousand dollars for that year, and three hundred men were constantly in the fight with these caterpillars, eggs, and moths. Since that date the sum has increased. and now the Legislature is petitioned for about five hundred thousand dollars to be expended in the expectation that this pest may be got under so it may be kept there for a few thousand a year.
I tell this story to show how easy it is for even a single species of insect to destroy all crops. It is only by the help of birds and other insects that destroy their eggs and caterpillars that man is able to live on this earth. If the gypsy moth had not been opposed wholesale there would not be a living orchard or green bit of woodland in New England to-day, and it would be useless to plant a crop.
