A correspondent suggests that "much if not all the diseases termed blight in the pear, rot in grape, etc., may be attributable to diseased roots." He says, "Pear wood, often when making cuttings for grafts, is found blackened or discolored; and if the cuttings are made late in spring, the discoloration is greater at the base of the young shoot than at the top." He also says, "that he has often observed blight to attack those trees most on which he has in spring found the greatest discoloration. He regards this disease as coming from the roots, which may have been made unhealthy, either by excessive stimulants and late fall growths, or by destroying actively developing foliage in the summer or growing season."

The diseases attendant upon grape culture and pear growing are yearly becoming more and more formidable, and we shall be glad if any sustainable theory of their cause be brought out. We give the above, hoping some of our many skillful fruit-growers will report to us of their views of its tenability.
