Mushrooms 
One brick of Mushroom Spawn is sufficient for 10 
square feet of bed. 
Mushrooms are more easily cultivated than many people 
imagine, and may be grown in any dark room or cellar 
where the temperature can be maintained at from fifty to 
sixty-five degrees. For the bed, use a mixture of horse 
manure and good fresh loam in equal proportions. Before 
being placed in the bed let this material be thoroughly 
mixed, and well turned three or four times to sweeten in 
some dry place. Upon a dry, firm bottom, proceed to make 
the bed, by spreading a thin layer of the prepared mixture 
and pound it firm till the bed is eight inches thick. Leave 
it thus for about a week, or till the temperature of the bed 
has subsided to ninety or ninety-five degrees. Then make 
holes about 12 inches apart, and put in each a piece of 
spawn about the size of a walnut. Cover the holes and press 
the soil solid and smooth. Let the bed remain in this con¬ 
dition ten days. Then cover with 2 inches of fresh loam. 
Over this place a few inches of straw. If the temperature 
is right, Mushrooms will appear in six to eight weeks 
from time of spawning. The bed will continue bearing about 
a month. After the first crop is gathered, spread over the 
bed an inch of fresh loam, and moisten with warm water. 
In the event of the surface of the bed getting very dry at 
any time, it should be moistened freely with water at a 
temperature of eighty to eighty-five degrees. 
If wanted by mail, add postage at parcel post rates.
