It need hardly be said that in such large mushroom- 

 houses rhubarb and sea-kale may be easily forced, and 

 barbe de capucin, endive,, &c. blanched. 



A small hot-water apparatus, with a 3-inch flow and 

 return pipe, affords the best means of heating a mush- 

 room-house which is not so situated that it may be heated 

 from the boilers of adjacent hothouses. The best position 

 for the mushroom-house is against a north wall. The 

 usual precautions for guarding against damp walls and 

 floor should be adopted in the case of the mushroom- 

 house, and the walls should be hollow. 



Forsytes mushroom-house is described by the designer 

 in London's Gardener's Magazine. Fig. 7 is a trans- 

 verse section, showing the arches under and over the 

 beds, the thoroughfare a is the middle, and the position 

 of the hot-water pipes, c ; b is an open shed and general 

 workshop, the receptacle of everything requiring protec- 

 tion, and too clumsy to be otherwise housed.
