This disease attacks the leaves, fruit, trunk and branches of apple trees, and less frequently of pears. On the leaves it causes small circular spots about one-eighth of an inch in diameter and usually with a purplish border; on the fruit it causes a firm, not a soft, brown rot which turns black late in the season; on the trunk and branches it causes dead areas, called cankers, some of these often of large size The disease on the leaves and fruit is seldom serious, but the cankers pro- duced on the trunk and branches often do very great damage The disease is worst in the counties east of Toronto, where it is a very com- mon sight to find numerous branches or even whole trees killed by it The fungus usually finds an entrance through some wound, such as those made by boots when climbing trees or by whiffle-trees when cultivating the orchard.
