On growing Mushrooms in Houses. 337

 his Imperial Majesty. 



The shed or house, used for growing Mushrooms, is found 

 of great utility in the severe climate of the more northern 

 parts of Europe, to protect Broccoli, and all other kinds of

 only variation which will be necessary, is the alteration of 

 the covering, by making it an hipped, instead of a lean-to

 each side ; and affords a space through the middle of the 

 house, three feet wide, for a double flue, and a walk upon it. 

 The walls should be nine inches thick, and the length of the 

 house as it may be judged necessary. When the outside of
