When an orchard isgrowing vigorously the young larva seems to be outwitted bythe rapid growth of the wood, but when an orchard is grassbound and growing very slowly, the trees are almost sure tosuffer, and oftentimes, if neglected, will be wholly destroyed. The beetle is about half an inch long, of a shinning green-ish black above, and like burnished copper underneath, and willbe readily recognized from the engraving.

Another formula is—Take one quart of soft soap boiled in two gallons of water,and while hot stir in one pint of Carbolic acid.
