trict observance of it will prevent a mistake in cold weather, for
then, if the bed is carelessly uncovered and much chilled, the crop will
come to an end, when perhaps it would, if properly handled, be at high
tide and full of profit. Another rule should be enforced, to this
effect, that every Mushroom must be taken out complete, and if the root
does not come with the stem, it must be dug out with a knife. Any
trifling with this rule will prove a costly mistake. The stem of a
Mushroom, if left in the ground, will produce nothing at all. But it may
attract flies, and it certainly will interfere with the movements of the
mycelium at that particular spot, and actually prevent the production of
any more Mushrooms. The old practitioners were accustomed to leave the
stem in the ground, and they were content with about one-third of the
crop now produced on beds that are, perhaps, not better made than were
theirs. But they had a notion about the powers of the root which
increased knowledge of the subject has shown to be fallacious.

==In Pastures.==--As already indicated, Mushrooms are often to be found in
abundance in well-stocked pastures during the late summer months, and
where favourable conditions exist it is an excellent plan to insert
pieces of spawn two inches deep in the turf in June and July.

==Turf Pits.==--The facility with which Mushrooms may be raised under
simple methods is illustrated by the practice of growing them inside the
turf walls of cool pits. In the country turf walls are common, and they
offer the advantage of growing Mushrooms in addition to the purpose they
usually serve. After determining the size of the pit, and accurately
marking it on the ground, cut the turf into narrow strips, say three or
four inches wide, and of exactly eighteen inches length. The strips
should be closely laid, grass side downwards, across the width of the
walls--not longitudinally--except at the corners, where the layers
should cross each other. The front and back walls to be rather above the
required height, because the turf always scales down a little, and the
two ends must gradually rise from front to back. The top layer may be
right side up, when it will keep green for a long time. As the work
proceeds insert lumps of spawn at intervals in every layer, about three
or four inches from the inside edge. A wooden frame will be requisite on
the top to carry the glass lights. This structure makes a useful cool
pit and a Mush
