and thus the accidents which originate from 

 negligence less frequently occur." 



These houses are made almost wholly of wood 

 and glass. The base is a frame of wood, which 

 rests horizontally upon posts fixed firm in the 

 ground, to which the frame is screwed by strong 

 iron screws ; the whole being so constructed as 

 to admit of being taken down and removed at 

 pleasure without violence, merely by undoing 

 the screws. They are capable of beino; formed 

 of any dimensions. A full explanation of their 

 nature, and the principles on which they pro- 

 duce their effecls, may be seen in the doctor's 

 work on the " Patent Hot-house." 



Hot-houses on this plan are constructed by 

 George Byfield, esq. architect, Craven-street, 

 Strand, London ; and Mr. Samuel Butler, Hot- 

 house-builder, Little Chel?ea. 



Nursery and Succession Houses. — Tn addition 

 to these Hot-houses, others of smaller dimen- 

 sions, for striking and raising the young plants 

 in, and as Succession Houses for receiving them 

 into afterwards, when of a year's growth, to 

 bring them forward to a proper size for being- 

 used as fruiting plants, are necessary, especially 

 where the pine-apple is cultivated upon an ex- 

 tensive scale, in order to afford full room in the 

 large Houses for the fruiting plants. 



These Houses may be erected either as appen- 

 dages to the main house, or detached at a little 

 distance, as most convenient. When the situ- 

 ation admits, it is however more convenient 

 and ornamental to join them in a line with the 

 main House, one at each end. They are form- 

 ed nearly of the same construction, only smaller 

 both in length, width, and height. 



Nursery-House. — This is sometimes formed in 

 the manner of a common detached bark-pit, 

 without any upright glasses in front, having a 

 wall all round, five or six feet behind, gradually 

 sloping at each end, to about four feet'in front, 

 and with only sliding glasses at top. Its di- 

 mensions must vary according to the extent of 

 plants. It is often termed simply the pit, as 

 the whole internal space in length and width is 

 allotted entirely as a pit for a bark -bed, without 

 any walk within, or door for entrance, the ne- 

 cessary culture being performed by sliding open 

 the glasses at top, the flues for the fires' being 

 formed in the upper part of the back wall/above the 

 surface height of the bark-bed. They may, how- 

 ever, be formed in the manner of the Houses. 



Succession House. — This should be constructed 

 with erect glasses in front, and sloping sashes 

 at top, with a door for entrance, and an alley or 

 walk next the back wall ; or, what is better, 

 continued round the bark-pit. And where 

 joined to the end of the House, it may be di- 



vided from it bv a sliding glass partition, hav- 

 and Hues, as the young 

 pirn p it! not at all limes require the same 

 the older pines. The 

 dimensions must < , ccording to circumstances 

 and ' e number of plants. See Stove and 

 Gkeen housi . 



HOT-HOUSE PLANTS, such of the ten- 

 der exotic or other kinds as require this sort of 

 house for their growth, prol dion, and preser- 

 vation in this climate. See Stove Plants. 



HOT- WALL, a range or extent of brick or 

 stone walling, fronted with glass-work, so as 

 to inclose a space of several feet in width, con- 

 structed with internal fire-flues, See. designed 

 for forcing fruit-trees to early production. 



Walls of this nature are mostly ranged 

 lengthways, east and west, to font the Full 

 sun; having the south side, or that exposed to 

 the sun, covered by a frame-work of glass, the 

 whole length and height, including a space of 

 but moderate width, as four, five, six, or eight 

 feet, for one row of trees behind, trained in the 

 wall-tree order, and extended from twenty or 

 thirty, to forty, fifty, or a hundred feet in 

 length; or of greater width, as ten, twelve, or 

 fifteen feet, in the forcing- house manner, to ad- 

 mit of a range of trained trees behind, and 

 others of lower growth forward ; and, in either 

 having internal flues for fire-heat in the main 

 wall, and continued round along towards the 

 front glass, or sometimes ranged longitudinally 

 along the middle space. Some Hot-walls have 

 likewise the front itudosure of glass-work, of 

 sufficient width to admit of forming an internal 

 pit, from four to five or six feet in width, the 

 length of the erection; in which to make a 

 bark bed, or sometimes a dung hot-bed, or oc- 

 casionally dung below, and bark above, to assist, 

 in conjunction with the fire heat of the flues, 

 in warming the internal air. 



Tn either method, a border of good mellow, 

 loam)', or other fertile earth, of proper width, 

 is formed against the main wall, in which to 

 plant the trees. Where there is no bark-bed. 

 the whole bottom space is formed of good earth, 

 having a narrow inclosure of glass, four, five, or 

 six feet, to have only a range of trees next the 

 wall, trained as wall-trees, or espaliers; or 

 sometimes made wider, to have wall-trees be- 

 hind, trained to the height of the wall, and 

 others trained in lower growth, in the internal 

 space forward, either in the espalier manner, or 

 as small dwarf-standards, or sometimes as ho- 

 rizontal dwarfs. Sec Dwarf Trees. 



When these are made of wide dimensions, 

 either I admit of a bark-pit, or to have the 

 whole internal bottom space of earth with trees
