Perhaps the reason why this plant does not spread more near Philadelphia may be found in the soil or climate. It is extremely abundant in some localities in western Massachusetts, and seemed to flourish most in cold, springy, or wet, mucky soils. It was not found at all in the immediate neighborhood where I lived, and I planted several in coves and low places along a stream, and they remained nearly in statu quo for several years, with no increase in number. When two or three of them were removed to a low, marshy piece of ground, where a small stream of water flowed slowly over the level surface among the scattered grass and scanty growth of small trees and shrubs, so that one could not walk on it without going over shoe in water, I very soon had the satisfaction of seeing hundreds of seedling plants spring up. The cowslip, as it was called in Massachusetts, was valued highly for greens, partly because it was much relished by many persons, and partly because it was the first plant that could be used for this purpose in spring.
