“Those covered from one-third to one-half of an inch came up more slowly, but evenly and strong; “Those buried from two-thirds of an inch to one inch came up in deficient numbers; and “Those buried from one to two inches never showed any signs of germination.” These statements are equally applicable to the sowing of seeds in general but especially if their relative size and the hardness of their covering are taken into account. Immediately after the bed is prepared the seed should be sown, the amount used varying according to quality, which latter may readily be tested by examining the embryos of a dozen seeds picked up at random from the heap. To ascertain whether seeds are good, the simplest way is to cut the sheath open with a sharp penknife, when the kernel ought to completely fill the entire coating or shell. Small seeds might be crushed by the nail, and if good, will leave traces of moisture or emit an odour of turpentine. Another method is to place, one after the other, say a dozen seeds taken at haphazard from the heap, on a red-hot iron. If good they will turn about with a cracking report; but if otherwise, combustion is slow and smoke is given off. Seed may, however, be considered good if the germinating test gives, say, 70 per cent. The quantity of seed to be sown on a given area will depend mainly on the quality and particular species. When sown broadcast, about a pound weight of larch, and full half a pound of Scotch, is allowed per 100 square ft. of seed-bed. Generally, however, drill sowing is resorted to, and in this case the following may be considered as about an average of the quantity used per 100 square ft.: Alder 7¾ ozs. Ash 5 ” Austrian Pine 4¼ ” Birch 6½ ” Elm 3½ ” Hornbeam 2¾ ” Larch 7½ ” Maple 5 ” Scotch fir 2¾ ” Silver ” 13 ” Spruce ” 3½ ”
