ters of the frames under the stages. If
he did not grow mushrooms under these stages the room would be
unoccupied, hence unproductive; but by occupying it with mushrooms he
not only gets peaches and snap beans at once out of the same greenhouse,
but also a crop of mushrooms, often worth as much as the other two.

In preparing the beds in the frames they were made up a foot deep, very
firm, and with New York stable manure brought direct from the cars.
There was no preliminary preparation of the manure. A layer of loam one
and one-half inches deep was then spread over the surface and forked
into the bed of manure one and one-half inches deep, so as to form an
earthy mat three inches deep. This was then packed solid with the feet,
and a two-inch layer of loose manure added all over. In about ten days
the temperature three inches below the surface was about 95 deg., and the
beds were then spawned. In spawning, drills were drawn across the beds
about a foot apart and just deep enough to touch but not penetrate the
earthy mat before referred to. The broken spawn was then sown in the
drills and covered with a layer of loam one and one-half to two inches
deep, which was tamped slightly. The sashes were then put on and tilted
up a little to let the moisture escape. By the time the mushrooms
appeared there was very little need of ventilating, as the condensation
of moisture on the glass was scarcely apparent; but ventilation is
easily guided by the appearance of moisture on the glass, the more of
this the more ventilation should be given. To begin with, there was no
attempt at shading the frames; but as soon as the mushrooms began to
appear the beds were shaded, and mostly by the crops of other plants on
the stages above them. These frame beds were made up last October, and
began bearing in December, and on March 14 Mr. Gardner wrote me: "The
mushrooms in my frames have done grandly. I cut large basketfuls to-day
of the finest mushrooms I have ever seen, some of them measuring five
inches in diameter before being fully expanded."

And further, in submitting the above notes to him for verification, he
adds: "There is one vital point we should impress upon all who grow
mushrooms in frames or under greenhouse benches, namely, that sudden
changes of temperature must be avoided. While light, in my opinion, is
good for mushrooms, it causes a rise of temperature, and this we must
guard against. In order to maintain a uniform temperature
