One-eighth acre to early cauliflower and cabbage, about 

 2,000 plants ; if transplanted would require two 6 x 12 frames, 

 200 to 250 plants being grown under each sash, or about 1,000 

 plants from each frame. 



These frames may be used again for tomato plants for the 

 same area, using about 450 plants. This will allow one sash 

 for every 55 plants. Plants for this area may be grown in 

 one frame, but would be crowded and not as stocky as if 

 given more room. 



One frame may be in use at the same time for eggplants 

 and peppers, two sash of each, growing 50 transplanted plants 

 under each sash. 



Two frames will be required for cucumbers, melons and early 

 squashes. 



If one wishes to grow extra-early lettuce, an estimate of 

 60 to 70 heads may be made to a sash. 



It is assumed that celery and late cabbages are to be started 

 in seed-beds in the open. 



If spinach is grown in frames, the sash used for one of 

 the late crops above may be used through the following winter. 



This makes a- total of five frames ; twenty sash and covers ; 

 manure, calculating at least three or four loads to a frame. 

 This is a liberal estimate of space, and should allow for all 

 ordinary loss of plants, and for discarding the weak and 

 inferior ones. It supposes that most or all the plants are to 

 be transplanted once or more in the frames. Many gar- 

 deners have less equipment of glass and do less transplanting. 



2. THE MAKING OF FRAMES 



In the planning of a coldframe or hotbed, the builder 

 must have in mind the following objects to be attained: 

 (1) sufficient and uniform supply of heat; (2) ample pro- 

 tection from cold; (3) means for ventilation; (4) facili- 

 ties for obtaining water; (5) plants to be near the glass, 

 and yet to have head-room for growth of tall kinds; (6)
