indoors, and which is apt to be true virgin spawn. The mushrooms are
generally of the common kind, grown from brick spawn, but occasionally a
much larger and heavier sort is produced, and this is the "horse"
mushroom. It is perfectly good to eat, only of coarser quality than the
other.

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
surrounded 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, N. 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 fermenting 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 season 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 January, 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 flat, seven to eight inches deep, with a casing of a
ten-inch-wide hemlock board set on edge at the back, and another of same
size against the front. The bed was made of horse droppings, six inches
deep, and molded over with fresh loam one and one-half inch deep. Over
the whole, and resting on the edges of the he
