The houses are placed in pairs, the furnaces for general use at the extreme ends of the range, and the auxiliary ones in the middle, where the steam-boiler is also placed, but worked by a fire apart. On the whole, no plan of Pine-stove that has yet appeared, is more simple, neat, economical, and complete than this; the only fault we have to them, is, that owing to the great thickness of wood employed on the bars of the sashes, they are rather dark and gloomy within; but this might easily be remedied by the substitution of light iron rafters, with wooden framed sashes sliding in them, but the bars of the sashes formed of iron. It is true, gloomy as these houses are, the Pines thrive in them as well as can be wished, but probably by having more light, they might thrive, so as to surpass all expectation. _Soil._ Good yellow loam, with a third of rotten dung, and some road grit to serve as sand. This is well mixed together, and passed through a wide screen, and the pots are well drained with three or four pieces of potsherd. _General management._ This differs in little or nothing from that of Mr. Andrews; and only from that of Mr. Baldwin in the crowns and suckers being struck in pots, instead of the bark, as is Mr. Baldwin’s practice. Supposing the crowns and suckers potted in September, they are not disturbed till the following March; such as are very forward, are shifted at once into large pots, and will show fruit in the course of that autumn, or within the year, and ripen their fruit in November or December, very desirable periods for the royal table, equally expeditious, as in Mr. Baldwin’s mode, and more so than in Cuba or Jamaica. The plants which are in a less forward state are disrooted entirely, put into pots according to their sizes, nursed all the summer in the pits, and moved to the larger houses in autumn, where they show fruit at various periods, during the winter, and in the following season; thus ripening their fruit at different periods, from eighteen months to two and a half years, from the time they were taken from the parent plants. The pots in which these plants are fruited, seldom exceed twelve inches in diameter. _Insects._ Various modes of getting rid of these was attempted both at Kew and Kensington; that which was finally successful was steeping for two or three hours in strong tobacco-water, as recommended by Miller; then washing in pure water two or three times--drying, planting, shading, and applying a brisk bottom heat, a moist atmosphere, and giving a little air. This recovered the plants, and future regimen continued them in the vigorous state of health in which they now are.
