JAN.] THE FRUIT GARDEN. 53 



front one or two feet high, on which is erected upright glass-work, 

 four or five feet perpendicular ; and from the top of these, a sloping 

 roof of glass frame, continued to the top of the back wall, supported 

 upon proper bearers three feet or three feet six inches distance, hav- 

 ing the top glasses in two ranges, an upper and under range, as before 

 advised, both of which, and those of the upright in front, made to 

 slide and move away occasionally : in this frame there will be room 

 to walk under the glass-work in any part, and there will be also due 

 room for the trees, both .dwarfs and low standards ; and then having 

 the whole ground space withinside of loamy or other good earth, as 

 in the other frame, you may plant your trees, some in one range 

 against the back wall, as peaches, nectarines, apricots, grapes, figs, 

 &c., six or eight feet asunder, erecting a trellis for training them 

 upon, and in front of these may be planted rows of young cherries, 

 both in small standards, half standards, and dwarfs ; the full stand- 

 ards to have about five feet stems ; each sort, both trained trees and 

 standards, to be planted when about from three to four or five years 

 old, as soon as they acquire a bearing state, with regular heads of 

 two or three feet extent at first planting. Having procured the trees 

 and the ground ready for their reception, may then plant one range 

 of the choicest sorts as before noticed, next the back wall two or 

 three yards asunder, the others in rows from back to front, at six or 

 eight feet distance, the tallest behind and the lowest in front, at three 

 or four feet distance in each row, making each row range against the 

 intervals of the trained tree behind ; or if they are all standards, and 

 half standards, there will be more room for several sorts of smaller 

 plants under them ; and as their branches will be nearer the top 

 glasses, it may be of particular advantage ; and in the intervals may 

 be planted some low currants, gooseberries, raspberries, strawberries, 

 dwarf beans, kidney beans, &c. But a frame of these dimensions is 

 sometimes planted entirely with standards, more particularly cherries, 

 as being more moderate shooters and soonest arrive to a bearing 

 state, so as to bear any tolerable quantity of fruit; planting them 

 five or six feet distance : sometimes standard plums, apricots, 

 peaches, and nectarines are also planted, and vines to train up under 

 the glasses. 



A frame of these dimensions, twenty-five feet long, may be worked 

 by one fire ; but if more than thirty feet in length, two furnaces for 

 fires, with each its set of flues, will be necessary. 



With respect to the age of trees for both the above kinds of fire- 

 heat forcing-frames, they should be from three to four or five years 

 old, with regular heads of branches, two or three feet extent, and 

 just arrived at a tolerable bearing state ; no very vigorous shooters 

 must be admitted, but such only as assume a moderate, regular 

 growth, and are trained in the nursery until they have acquired a 

 proper size, each as directed under its respective head, whether as 

 wall trees or standards; they are to be transplanted into the frame in 

 October or November to remain for forcing ; but should be permitted 

 to have a year or two's growth here before you begin forcing them, 

 that they may be firmly rooted; during which time all the glasses 

 should be entirely away, that the trees may have the full air till
