1 FEAMES are structures employed either 

 in forcing, or in protecting plants, and 

 are of various sizes. 



According to the good practical rules 



'. of Abercromhie, the one - light frame 

 may be about four feet and a half in 

 width from back to front, and three feet 

 six inches the other way; fifteen or 

 eighteen inches high in the back, and nine 

 in front, with a glass sash or light, made 

 to fit the top completely, to slide up and 

 down, and move away occasionally. 



The two-light frame may be seven feet 

 long, four and a half wide, and fifteen or 

 eighteen inches high in the back, with 

 bars reaching from it at top to the front, 

 serving both to strengthen the frame and 

 help to support the lights ; the two lights 

 to be each three feet six inches wide, 

 made to fit the top of the frame exactly. 

 The three-light frame should be ten feet 

 six inches long, four and a half wide, and 

 from eighteen inches to two feet high in 

 the back, and from nine to twelve or fifteen 

 inches in front observing that those 

 designed principally for the culture of 

 melons may be rather deeper than for 

 encumbers, because they generally re- 

 quire a greater depth of mould or earth 

 on the beds ; though frames, eighteen or 

 twenty inches in the back, and from nine 

 to twelve in front, are often made to serve 

 occasionally both for cucumbers and me- 

 lons. Each frame should have two cross 

 bars, ranging from the top of the back to 

 that of the front, at three feet six inches 

 distance, to strengthen the frame, and 

 support the lights ; and the three lights 



.hould be each three feet six inches wide ; 

 the whole together being made to fit the 

 top of the frame exactly, every way in 

 length and width. 



Sometimes the above sort of frames are 

 made of larger dimensions than before 

 specified ; but in respect to this it should 

 be observed, that if larger they are very 

 inconvenient to move to different parts 

 where they may be occasionally wanted, 

 and require more heat to warm the in- 

 ternal air ; and in respect to depth par- 

 ticularly, if they are but just deep enough 

 to contain a due depth of mould, and for 

 the plants to have moderate room to 

 grow, they will be better than if deeper, 

 as the plants will be then always near the 

 glasses, which is an essential consideration 

 in early work, and the internal air will 

 be more effectually supported in a due 

 temperature of warmth ; for the deeper 

 the frame, the less in proportion will be 

 the heat of the internal air, and the 

 plants being far from the glasses will be 

 some disadvantage in their early growth. 

 Besides, a too deep frame, both in early 

 and late work, is apt to draw the plants 

 up weakly ; for they always naturally as- 

 pire towards the glasses, and the more 

 space there is, the more they will run up ; 

 for which reason the London kitchen- 

 gardeners have many of their frames not 

 more than fourteen or fifteen inches high 

 behind, and seven in front, especially 

 those which are intended to winter the 

 more tender young plants, such as cauli- 

 flower and lettuce, and for raising early 

 small salad, herbs, radishes, &c. 



The wood-work of the back, ends, and 

 front should be of inch or inch and a 

 quarter deal, as before observed, which 

 should be all neatly planed even and 

 smooth on both sides; and the joints, in 

 framing them together, should be so close 

 that no wet or air can enter. The 

 cross-bars or bearers at top, for the sup- 

 port of the glasses, should he about three 

 inches broad and one thick, and neatly 

 dovetailed in at back and front even with 

 both edges, that the lights may shut 

 down close, each having a groove or chan- 

 nel along the middle to conduct off all 

 wet falling between the lights. At the 

 end of each frame, at top, should be a thin 

 slip of board, four inches broad, up to 

 the outside of the lights, being necessary 

 to guard against cutting winds rushing 

 in at that part immediately upon the 

 plants, when th'e lights are occasionally
