344 On growing Mushrooms in Houses. 



the stems of those that are cut, as they would rot, to the 

 great injury of those that surround them. 



If the preceding directions are properly attended to, in the 

 management of the beds, they will continue to bear several 

 months, and a constant supply may be kept by earthing one 

 bed or more, every two or three months, according to the 

 quantity of mushrooms, required at one season. When the 

 beds are in full bearing, if the mushrooms become long in 

 their stems, and weak, it is certain, the temperature of the 

 building is too high ; consequently, air must be admitted in 

 proportion to the heat. 



Of renovating the old beds. As your beds begin to decline 

 in bearing, and produce but few mushrooms, take off the 

 earth clean from the dung, and if you find the latter de- 

 cayed, destroy the beds and replace them by new ones, 

 being careful to select any good spawn that may present

 compost, as before recommended, three or four inches thick, 

 mixing it a little with the old, and beat it as before. By ad- 

 hering to this mode of renovating the old beds, a continual 

 supply may be kept up. 



Management of Mushrooms in a cellar, §c. Mushrooms 

 may likewise be produced in a cellar, or any other vaulted 

 place, with equal success, and not unfrequently to greater 

 advantage as to crop, than in a shed, or other building, 

 that is level with the surface of the earth. The same rules 

 of management are to be observed, as directed for the shed. 

 The peculiar advantage of a cellar, is, that no fire is ne- 

 cessary, and less water, the application of which so fre-
