From observation of the growth of many of our native trees and plants I am inclined to sustain the opinion expressed by R. D. in his notes on the Beech Forests of Illinois.

We find many forest trees, as well as plants of smaller growth, confined to certain limits, and these limits very frequently seem to conform to the geological formation of the substrata, where no conditions of shade or the absence of it, humidity or the reverse, could have been the cause of this choice that induces the yellow locust to grow spontaneously on one side of a ravine and not on the other; and many other trees show a discrimination in a choice of soil for their native growth, where the seed must have been equally disseminated over a wide area.

Some of our native plants of great beauty are dying out, as we are destroying some of the condi_ tions essential to their health. Has any one suc. ceeded in growing Epigea Repens in cultivated soil? Colora, Md.

[There is a garden in Germantown in which the Trailing arbutus was transplanted years ago, and the plant has spread and seems quite at home. In the writer's garden a plant put in a shaded rockery some three years since holds its own fairly well - Ed. G. M].
