The question was discussed whether trees grown on soils which had been previously occupied with trees, and enriched by manuring, was as good as those on new soils, or those previously occupied with farm crops merely. The members generally had found a second crop of nursery trees from the Same land, inferior to the first, even with considerable manuring, unless some years of "rest" intervened, which period appeared to vary with the natural strength of the soil from two to eight years. Rotation in tree crops was found important as well as in farming; for example, it was stated by T. C. Maxwell, of Geneva, that he grew cherry seedlings on land one-half of which was previously used for dwarf pears, and the other half for cherries. The cherries after the cherries, were only one-half as large as after dwarf pears. He had grown fine cherries after a crop of peach-trees. Some of the members, and especially P. Barry, thought that trees raised on manured old ground were not so healthy as those on new soil, the latter affording fibrous roots in abundance, while on old soils made rich with manure, the roots are thick, forky, and few in number.
