The Root.—The root of a Rose in its early stages, soon after its emission from the seed, is a tap-root, i. e., one having the form of a long cone, with a stoutish trunk descending relatively to a considerable depth, and giving ofi: numerous branches at a somewhat obtuse angle. The root is thus so organised as to secure firm attachment to the soil, and a supply of nutriment at various depths. The root of a. Rose (we are speaking more particularly of wild ones) is well equipped for taking part in the competition with other vegetable forms. As the plant grows, the base of the stem and the upper part of the root become more and more woody, and ultimately form a thick "root-stock," which does not itself absorb food, but which serves as a store-place for the food, which is derived partly from matters taken up by the root-hairs and finest root-fibrils, partly by the aid of gases ah- sorbed from the atmos- phere by the leaves. By this conjoint agency of leaves and root nutritive matter is formed, and those portions of it which are not used up by the growing plant are stored in the reser- voir afforded by the younger and outer portions of the woody stems, and more particu- larly in the root- stock. There they remain till requisitioned in spring to supply the needs of the growing parts. The thick butt-end of a Roae-stock, as taken from the hedge-row for purposes of "budding," has
