The plan given requires no succession-house; but he describes a frame used by many persons for growing young Pines, “made in the same manner as common hot-bed frames, but higher and broader; that is, three feet higher at the back, sloping to one and a half in front, and six feet wide.” These cover a tan-pit causewayed at bottom, and surrounded by a stone wall. It is very proper, he says, to have these frames at work as well as the stoves. He also mentions flued pits, such as are described by Miller (Sect. 2.) Both stoves and pits he covers with boards, tarpauling, or mats, at night; and the fuel he uses is coal or peat, avoiding wood as of too rapid consumption. _Soil._ Two-thirds of good loamy kitchen-garden mould, one-third of old rotten cows’ dung, or hot-bed dung, and to every eight barrowfuls of this a barrowful of sea-sand. He adds, “If your ground is naturally sandy, after having mixed it with the dung above mentioned, add thereto a third of good fat marl; which succeeded so well with me, that in this compost I had much larger fruit than in any other compound which I used to give them, which induced me to put, at all times, a good _deal of marl_ in the compost I used for these plants.” This mixture should lie for six months in those parts of the garden which are airy and least exposed to the sun; after the first three months, turn it over every fortnight. _Scots Gardeners’ Directory_, 2d edit. p. 124. _General management._ The same as is given by Miller. He tried some plants turned out of the pots with their balls, and planted in the bark for the last nine months before the fruit ripened, and found the fruit larger and earlier, but not better flavoured than that of the plants in pots. In shifting, he never cuts off any of the leaves; “for it is certain,” he adds, “that the leaves of all plants and trees bear the same office to them, as the pulmonary vessels do to human bodies.” He waters over the leaves when the plants have shewn fruit; because the fruit stalks, occupying what in young plants was a hollow tube, no injury can happen. P. 129. _Insects._ At the first appearance of the bug, he picks off the scale with a pin; and if that does not clean the leaves, he washes with a sponge; and, in extreme cases, uses Miller’s mode.
