One seedling of Carpathian walnut was not damaged seriously except for some slight terminal twig killing. Another tree, however, had most of the smaller branches killed. Hickories and chestnuts were apparently not seriously damaged but some seedlings of the Japanese walnut were killed to the ground. +Walnut and Hickory Plantings+ At the orchard of the Department of Pomology of Cornell University there is a large collection of walnut and hickory varieties and other nut trees. It is not known exactly what the temperatures were in this location but an exposed location half a mile distant had a minimum September temperature recorded of 24 deg.F. and minimum winter temperature of -20 deg.F. The planting in question is on two levels and on a hillside. The damage on the hillside and the upper level was relatively less than on the lowlands where apparently the air drainage was poor. Probably the temperature in the lowlands may have reached 20 deg.F. in September and -25 deg.F. in the winter. At any rate, the damage to the trees was much more severe than in the West Hill location where the temperature reached 23 deg.F. in September. Injury to the black walnut on the higher land and on the hillside was mostly the killing back of the twigs and smaller branches. On some trees, the petioles of last year's leaves were still attached to the dead twigs late the following summer, showing that the freeze occurred before the abscission layers had formed. The dozen or more varieties of black walnut on the higher land showed little difference between them except that the Elmer Myers showed somewhat greater injury. On the low ground, many varieties including Murphy, Edmunds, Benton, Ohio, Todd, and Stambaugh were killed to the ground or back to the main branches of the trunk. Of three Thomas trees, about 20 years old, one was killed outright, one severely injured, and the other injured only in the twigs. Apparently the difference in these three trees was related to the size of the crop on the trees, although no definite data are available on this point. Walnuts showing little or no injury were: Mintle and Tasterite. Neither of these had had a crop in 1947. Many of the varieties of hickory were injured as was the native bitternut, _Carya cordiformis_. This injury consisted mostly of the killing back of the lower limbs and twigs with some varieties being killed outright. Killing of the lower limbs as compared with the tops of the trees is probably related to lower temperatures near the ground due to temperature inversion and possibly to the fact that the lower branches were somewhat weaker in their growth. This sort of injury is common with fruit trees.
