50 THE FRUIT GARDEN. [JAN. 



cious dimensions, to admit of making a substantial hot-bed of dung 

 internally, both to produce an increased degree of heat, and wherein 

 to plunge pots of several sorts of flowering and esculent plants to 

 bring them forward in growth, being assisted also with a lining of 

 hot dung applied to the exterior of the back part of the frame, as 

 explained in the foregoing; and for the internal hot-bed should form 

 a bottom pit of proper width, length, and depth, making the bed 

 therein a yard depth of good hot dung, covering the top with light 

 dry earth, or old or new tan-bark, six or eight inches thick, in which 

 to plunge the pots of flowers, or those of early esculents, such as 

 kidney-beans, peas, strawberries, salading, &c. 



JBark-bed heat. This kind of forcing- frame, or rather forcing- 

 house, is worked by aid of a tanner's bark hot-bed, formed in a pit 

 withiuside the whole length. 



This frame may be formed either of wood or brick-work, and 

 fronted, &c., with sashes of glass like the former ; the length may be 

 ten, twenty, or thirty feet, or more, eight or ten wide, and six or 

 eight high; and may be constructed either nearly like the dung- 

 heat frame, six or eight feet behind, and one in front, the ends con- 

 formable, and sloping frames of glass-work raised from the front, 

 sloping either quite to the top of the backfall, or to incline only 

 about one-half towards that part, meeting a covered roof at top, half 

 way, which should be raised high enough in front to throw the water 

 off behind, as well as to admit as much sun as possible to every part 

 of the frame, or it may be constructed with an upright front of glass, 

 head high, and a sloping roof of glass-work, ranging from the up- 

 right front to the top of the back wall, which is rather the most 

 eligible form, both for convenience and benefit of the plants ; either 

 of which constructions may be erected detached, or against a south 

 wall already built, which will serve for the back and save some ex- 

 pense; the ends may either be of wood or brick, and the glass-work 

 in every part should be made to move on and off, as well 'as to slide 

 backward and forward to give air, and to do other necessary work ; 

 and at one end, near the back wall, may be a door to enter occasion- 

 ally, and withinside must be a pit for the bark-bed three feet deep, 

 part sunk, and the greater part raised, continued the whole length 

 and width, except about a foot and a half alley to go in to perform 

 the necessary culture, as well as to view and gather the produce of 

 the different plants. 



The pit within is to be filled with new tan any time in winter or 

 spring you intend to begin forcing, though January is soon enough, 

 and the beginning of February is not too late ; the bark will support 

 a growing heat three months, and if then stirred up to the bottom, 

 will renew its heat, and continue it two months longer. 



In this frame may plunge in the bark-bed pots of roses, or any 

 other choice flowering shrubs you would force into an early bloom ; 

 likewise may place pots of strawberries towards the front and top 

 glasses ; and pots of kidney beans and early dwarf peas may be 

 placed in any part of the frame ; also pots of dwarf fruit-trees, before 

 mentioned, pots of double pinks, carnations, and any other moderate 

 growing fibrous-rooted perennials, as well as any sorts of bulbous or
