Those plants which are reared in green or hot-houses, and are raised from seed, as well as a great variety of tender annu als, are generally produced from hot-beds,.
made by collecting fresh stable-dung, or tanner's bark, while capable of affording a great degree of heat. Over these beds, which are sometimes framed in withwood work for masonry, fine soil is laid to the depth of four, five, or six inches, or in some cases more, and glass frames are fitted as covers, in such manner as to open to any desired extent. When the first
heat has subsided, and the temperature is such as not to scorch, the seeds of me lons, cucumbers, &c. may be sown, or the pots, containing curious plants, may he partly buried, so as to obtain a greater degree of heat than is afforded by the air without the frame. In this manner, the most tender exotics may be propagated ; indeed many become gradually so inured to our climate, as to be perfectly habitua ted ; and after fifteen or twenty genera. tions (or seasons, if not very perishable) may in some instances be treated the same as our tender indigenous plants. Such, however, as are not disposed ,so to assi milate, must be preserved in green houses, or eventually be kept in hot houses during the cold months ; being there confined in an artificial atmosphere, highly rarefied by means of a fire, which warms a variety of flues that every where intersect the walls of the building. See HOT-HOUSE.
Having said thus much, in general terms, regarding the trees, shrubs, and ordinarily appropriated to gardens and pleasure-grounds, we shall give the reader a brief code of instruction as to the seasons and modes appropriate to each individually, arranging the whole in form of a calendar.
JANUARY.January.
Eitchen-garden. Make up your hot-beds for melons, cucumbers, &c.; for early produce, select the romana and canta loupe melons, and the early prickly cu cumber. The plants will rise in a week, but you should never keep them so hot as to steam the glasses. Sow successive ly, in case of accidents, to which this class are very subject. If the beds cool too much, lay fresh litter all around them ; or, if practicable, rake out some of the old litter, and fill up with very fresh dung; avoiding much pressure. The outside dressing will require to be changed every fortnight, as the heat will in that time be greatly abated. When the plants have made two good shoots, exclusive of their first leaves, you may remove the pots, in which they were sown, to a larger bed, where they are to remain, stripping off such shoots just beyond their second joints. In such beds you may force aspa ragus, lettuce, small-salading, love apples, radishes and an infinite variety of vege tables for early use : this will, however, require extensive and numerous beds.
