ers from the roots of roses, and such other shrubs as produce them, 
and are worthy of cultivation. 
Hedges of the various kinds of haAv-thorn, hornbeam, beech, elm, 
privet, white mulberry, &c. may now be planted. Make and repair 
grass and gravel walks; keep such as are made in clean and neat 
order, and give them occasional rollings. 
Sow hardy annual and perennial flower seeds, and do the various 
other works directed to be done in the flower-garden and pleasure-

THE GREEN-HOUSE. 
A Green-house, is a garden-building fronted with glass, serv- 
ing as a winter residence for tender plants from the warmer parts 
of the world, which require no more artificial heat, than what is 
barely sufficient to keep off frost, and dispel sueh damps as may 
arise in the house, occasioned by the perspiration of the plants or a 
long continuance of moist weather. 
A very considerable share of the vegetable creation which, in 
their respective native countries, grow naturally in open fields, &c. 
in all seasons; require when cultivated in less favourable climates, 
protection in winter; but observe, however, that those of the Green- 
house department, being from the warmer parts of the world, 
require protection from frost only, not needing aid of artificial heat 
like stove plants, which are generally natives of the hottest regions, 
except in very severe weather; but the aid of a moderate fire, 
burned in a furnace contrived outside, either in the end, or back 
wall, communicating the heat to the flues or funnels ranging along 
the inside, will be necessary, not only in severe frosts, but also 
in moist foggy weather; a moderate fire now and then will 
dry up the damps, which would otherwise prove pernicious to 
several of the more tender kinds, especially to those of succulent 
habits. 
A green-house should generally stand in the pleasure-ground, 
and if possible, upon a somewhat elevated and dry spot fronting 
the south, and where the sun has full access from its rising to set- 
ting; the building ought to be of brick, or stone, having the front 
almost wholly of glass-work, ranging lengthwise east and west, 
and constructed upon an ornamental plan. 
As to its general dimensions, with respect to length, width, and 
height, it may be from ten, to fifty feet or more long, according to 
the number of plants which you intend it should contain; and its 
width in the clear, from ten or fifteen to twenty feet, though for a 
middle sized house, fifteen or eighteen feet is sufficient; its height 
to the top of the upright front glasses, equal to its width; as to erect-
