ter three or four days, and re-stack, being careful to put the
manure from the top and sides of the pile now on the inside.

Having now ready the heating apparatus and the superstructure of our
miniature greenhouse, the building of it is a very simple matter. If the
ground is frozen, spread the manure in a low, flat heap nine or ten feet
on each side, a foot and a half deep, and as long as the number of sash
to be used demands. A cord of manure thus furnishes a bed for about
three sash, not counting for the ends of the string or row. This heap
should be well trodden down and upon it should be placed the box or
frame upon which the sash are to rest. In using this method it will be
more convenient to have the frame made up beforehand and ready to place
upon the manure, as shown in one of the illustrations. This should be at
least twelve inches high at the front and some half a foot higher at the
back. Fill in with at least four inches--better six--of good garden soil
containing plenty of humus so that it may allow water to soak through
readily.

The other method is to construct the frames on the ground before severe
freezing, and in this case the front should be at least twenty-four
inches high, part of which--not more than half--may be below the ground
level. The 2 x 12 inch planks, when used, are handled as follows: stakes
are driven in to support the back plank some two or three inches above
the ground,--which should, of course, be level. The front plank is sunk
two or three inches into the ground and held upright by stakes on the
outside, nailed on. Remove enough dirt from inside the frame to bank up
the planks about halfway on the outside. When this banking has frozen to
a depth of two or three inches, cover with rough manure or litter to
keep frost from striking through. The manure for heating should be
prepared as above and put in to the depth of a foot, trodden down, first
removing four to six inches of soil to be put back on top of the
manure,--a cord of the latter, in this case, serving seven sashes. The
vegetables to be grown, and the season and climate, will determine the
depth of manure required--it will be from one to two feet,--the latter
depth seldom being necessary.

It must not be overlooked that this manure, when spent for heating
purposes, is still as good as ever to enrich the garden, so that the
expense of putting it in and removing it from the frames is all that you
can fairly charge up against yo
