«nd thus the accidents which originate from 

 negligence less tVequently occur." 



Tlifsc houses are made almost wholly of wood 

 and iilass. The: base is a frame of wood, w Iiich 

 rests horizontally upon posis fixed lirm in tlie 

 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 

 tlie screws. They are capable of being formeil 

 of any dimensions. A full explanation of their 

 nature, and the principles on which thev pro- 

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

 work on the " Patent Hot-house." 



Hot-houses on this plan are constructed by 

 George Bvfield, esq. architect, Craven-street, 

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

 liouse-builder, Little Chelsea. 



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 aiford full room in tht 

 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. Thev are form- 

 ed nearly of the same construction, only smaller 

 both in length, width, and height. 



Nurseri/- 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 to]), the flues for the fires being 

 formediutheupperpartof theback wall,al)ove 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 by a sliding glass partition, hav- 

 ing a Separate furnace and llucs, as the vounf 

 pine plants do not at all times require the same 

 degree of fire-heat as the older pines. The 

 dimensions must vary according to circumstances 

 and the number of plants. See Stove and 

 Gkeen-house. 



HOT-HOUSE PLANIS, such of the ten- 

 der exotic or other kinds as require this sort of 

 house for their growth, protection, 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 intcnial (ire-flues, &c. desi<rned 

 for forcing fruit-trees to early production. 



Walls of this nature are mostly ranged 

 lengthways, east and west, to front the Tull 

 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 

 hut moderate width, as four, five, six, or eisrht 

 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 

 iiftecn 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 inclosure 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 

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

 casionally dung below, and bark above, to assist,- 

 in conjunction with the fire heat of the flucsj 

 in warming the internal air. 



Tn either method, a border of good mellow, 

 loamy, or other fertile earth, of proper width, 

 is formed against the main wall, in which to 

 plant the trees. Where there is no bark-bid, 

 the wholobottom space is Ibrmed of good earth, 

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

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

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

 sometimes made wider, to have w;dl trees be- 

 hind, trained to the height of the wall, and 

 others trained in lower growth, in the internal 

 space forward, cither in the espalier manner, oc 

 as small dwarf-standards, or sometimes as ho- 

 rizontal dwarfs. Sec Dwahf Treks. 



When these are made of wide dimension", 

 either to admit of a bark-pit, or to have tlit 

 whole internal bottom space of earth with trees
