GROWING MUSHROOMS IN GREENHOUSES.

A fair and certain crop can be obtained by planting- 
pieces of spawn in the beds here and there between the 
plants and where they will be least likely to be soaked 
with water. In order to further insure the development 
of the spawn, holes about the size of a pint cup should 
be scooped out here and there over the bed, and filled up 
solidly with quite fresh but dry horse droppings, with the 
piece of spawn in the middle, and covered over on top 
with an inch of loam, so as to leave the whole surface of 
the bed level. So small a quantity of dry manure sur¬ 
rounded with cold earth will not heat perceptibly, and 
the moisture of the loam about it will soon moisten it, 
no matter how dry it may be. The dry, fresh droppings 
are the very best material for starting the mycelium 
into growth. 
Growing Mushrooms in Rose Houses. —George 
Savage, the head gardener at Mr. Kimball’s greenhouses, 
Rochester, 1ST. Y., grows mushrooms very successfully 
under the benches of the rose houses. When he makes 
up his earliest mushroom beds in the fall the rose house 
is kept cool, and this is an advantage to the mushroom 
beds, which get all the warmth they need from the fer¬ 
menting manure; but as November advances, and the 
heat in the beds begins to wane the rose houses are 
“started,” and this artificial warmth comes in good sea¬ 
son to benefit the growing mushrooms. The roses, in 
this case, are planted out on benches, hence there is 
scarcely any dripping of water from above upon the 
mushroom beds below. 
Mr. George Grant, of Mamaroneck, N. Y., who grows 
mushrooms in the greenhouse, I called to see last Jan¬ 
uary, and was very much pleased with his simple and 
successful method. The beds were then in fine bearing, 
very full, and the crop was of the best quality. The 
beds were made upon the earthen floor of his tomato¬ 
forcing house and under the back bench. The bed was
