If ever this evil was visible, it is so this summer. The recent exceptionally severe drouth brought it to light. Young plants that were raised in and transplanted from beds in frames, boxes or open borders, took far more readily to their new quarters, grew and survived the drouth with much less impurity than those raised in and transplanted from pots. Thrifty plants raised in pots extend their roots round and round within the pots until a ball is formed, and this ball if left unraveled, in after life remains an impediment to the luxuriance of the plant, and under adverse circumstances, such as a severe drouth at and immediately after the time of planting, renders the plant an easy prey to starvation, insects, or other likely evils.
