The best material for potting is good rich fibry loam, and fibry sandy peat taken from elevated positions, one to two inches thick, in dry weather, and the turfs turned upside down, for three or six months. There is no necessity to keep it longer if kept dry, but the peat and loam must be kept separate until required. In the absence of these, a thin layer of turf from old alluvial deposits will be the best sub stitute ; and sometimes we may get a little from hedge-rows, or the sides of roads not much frequented, that will do fairly well. We will also require a quantity of sweet, well rotted manure. That from the cow yard or stable will dp; good leaf mould, and clean gritty sand— silver sand is the best, but not to be got around the city, so we must get the nearest we can to it; but avoid sea-water sand, as not only the salt is injurious, but it harbors insects that impede the growth. Some olean empty pots, and potshards or soft bricks, broken up into various sizes sizes, will put us in a fair way for a start. The last paper gave us clear and ela- , borate directions for raising young plants from the germ or seed ; and we will sup pose that those to be grown from cuttings are already struck, and fit to be removed to the first sized pot, which may be three inches or four inches across, ac cording to the nature of the plants. Large-rooted ones, such as fuschiaa, gera niums, and chrysanthemums, may have the larger size ; while heaths, epacris, and the like, must be smaller. The same rule holds good with regard to drainage. The fibrous rooted varieties require care ful draiuage throughout, as directed hereafter, while the others with care will answer with one potshard placed over the bottom drain-hole. The various. materials must now be brought in and mixed into a compost suitable for plant food.
