Mr. Du Breuil also refers to Leport's liquid mastic in terms of commendation, but speaks of it as a secret composition. Downing recommends melting together: Bees-wax 3 parts. Rosin 3 parts. Tallow 2 parts. He says, the common wax of the French is Pitch one-half pound. Bees-wax one-half pound. Cow-dung one pound. To be boiled together, and laid on with a brush, and for using cold or on strips of muslin, equal parts of tallow, bees-wax, and rosin, some preferring a little more tallow. J.J. Thomas, whose practical knowledge is proverbial, recommends for its cheapness Linseed oil one pint. Rosin six pounds. Bees-wax one pound. Melted together, to be applied warm with a brush, or to be put on paper or muslin, or worked with wet hands into a mass and drawn out into ribbons. The season for grafting is quite a prolonged one, if we include the period during which it may be done in the house, and the ability we have of retarding the scions by cold, using ice. It should be done while the grafts are dormant, which is at any time from the fall of the leaf until the swelling of the buds. As the grafts would be likely to suffer from prolonged exposure, out-door grafting is done just before vegetation commences in the spring, but may be prolonged until the stocks are in full leaf, by keeping back the scions, in which case, however, there is more danger to the stock unless a portion of its foliage is allowed to remain to keep up the circulation; under these circumstances, too, side-grafting is sometimes used with the same view. The stone fruits are worked first; cherries, plums, and peaches, then pears and apples. With regard to grafting grapes, there is a diversity of opinion. Some operators prefer very early in the season, as in February, and others wait until the leaves have appeared upon the vine to be grafted. SCIONS OR GRAFTS are to be selected from healthy plants of the variety we wish to propagate. They should be the growth of the previous year, of average size, well developed, and with good buds, those having flower buds are rejected. If the shoots be too strong, they are often furnished with poor buds, and are more pithy, and therefore they are more difficult to work and are less likely to grow. Grafts, cut from young bearing orchards, are the best, and being cut from fruiting trees, this enables us to be certain as to correctness of the varieties to be propagated; but they are generally and most rapidly collected from young nursery trees, and as an orchardist or nurseryman should be able to judge of all the varieties he cultivates by the appearance of their growth, foliage, bark, dots, etc., there is little danger in taking the scions from such untested trees.
