702. _To prevent Ink from moulding._--Half-a-dozen cloves, bruised with gum-arabic, are to be put into the bottle. If a very fine ink is wanted, white wine, or vinegar and water, should be used, instead of water alone. 703. _To make Indian Ink._--Put six lighted wicks into a dish of oil; hang an iron or tin concave cover over it, so as to receive all the smoke; when there is a sufficient quantity of soot settled to the cover, then take it off gently with a feather upon a sheet of paper, and mix it up with gum-tragacanth to a proper consistence. N. B. The clearest oil makes the finest soot, consequently the best ink. 704. _Indian Ink._--Take horse-beans, burn them till they are perfectly black, grind them to a fine powder, and, with weak gum-arabic water make it into a paste, and form it into long square cakes. 705. _To make China Ink._--Take dried black horse-beans, burn them to a powder, mix them up with gum-arabic water, and bring them to a mass; press it well, and let it dry. MANAGEMENT OF CANARY-BIRDS. 706. Canary-birds, that are kept tame, will breed three or four times in the year. Towards the middle of March, begin to match your birds, putting one cock and hen into the breeding-cage, which should be large, so that the birds may have room to fly and exercise themselves. Place two boxes or little basket-nests in the cage, for the hen to lay her eggs in, because she will sometimes have a second brood before the first are fit to fly, leaving the care of them to the father-bird, who feeds and brings them up with much care, while she is sitting on her second nest of eggs. Whilst your birds are pairing, feed them, besides the usual seeds, with the yolks of hard-boiled eggs, bread that has been moistened, or, if hard, grated fine, and pounded almond-meat. When the young birds are to be fed, give the same soft food, and be sure have it fresh every day; also furnish the old birds with fresh greens, such as cabbage-lettuce, chick weed, groundsel, &c. Give fresh water every day, and a clean bath every morning. The hen lays, commonly, four or five eggs, and sits fourteen days. When the young are hatched, leave them to the care of the old birds, to nurse and bring up till they can fly and feed themselves, which is, usually, in about twenty days. 707. _Gold and Silver Fish._--Pure rain-water is best to keep these delicate little creatures in; they should never be put into water that has been boiled. It is a good plan to throw them in the morning into a large bowl of fresh water, with a few bread-crumbs in it, and let them remain there an hour. Then put them in pure fresh water in their vases. The water should be changed every day. If the bread remains in the water to become sour, it will kill the fish.
