66 THE FORCING GARDEN. 



crops, without any loss of time, and this house will 

 answer the purpose exactly. 



A pit four feet wide should run round three sides 

 of the house, i.e. along the two sides, and across the 

 further end from the door. This section of it across 

 the end will be found very useful for forcing Khubarb 

 and Asparagus, or for plunging pots of forced Eoses, 

 Lily-of-the-valley, &c. The side pit on the south will 

 be the best for winter Cucumbers, and the other side 

 will be found the best for the succession of summer 

 Cucumbers. The vines will cover the whole of the 

 roof, or nearly so. It will be seen by the illustration 

 that the pit is so situated as to admit of a pipe running 

 between the wall of the house and the pit to supply the 

 heat at the lowest part of the house on the south side, 

 but none on the north side, where it is not really wanted 

 for summer Cucumbers. But for growing winter 

 Cucumbers a flow-and-return pipe is indispensable. 



The pits may be filled with half stable dung and 

 half leaves, which should be well packed and thoroughly 

 mixed, the beds being well trodden in and quite filled. 

 The manure will sink by fermenting. 



For this house a good boiler is necessary, such as 

 the thirty-six-inch tubular saddle boiler, i.e. thirty-six 

 inches long, which will heat about 450 feet of four-inch 

 pipe well. The price is about 71. Or the improved 

 conical boiler of thirty inches, which will heat about 

 600 feet of four-inch pipe, the cost of which is 101. This 

 last is a powerful boiler, causing but little trouble, and 

 perhaps the most economical as regards firing and 

 attention, and, in conjunction with the sure and safe cir- 

 cumstances connected with 6 double glazing ' of s'uch 

 a house, no better or less expensive boiler can be had.
