tree, quartered--but sizable, so as to appear decent--and the
insides facing each other as they stand up, lined to a surface to
receive the planking. Of course, when the posts are set in the ground,
they are to show a square form, or skeleton of what the building is to
be when completed. When this is done, square off the top of each post to
a level, all round; then frame, or spike on to each line of posts a
plate, say six inches wide, and four to six inches deep, and stay the
two plates together strongly, so as to form a double frame. Now, plank,
or board up closely the _inside_ of each line of posts, that the space
between them shall be a fair surface. Cut out, or leave out a space for
a door in the center of the side where you want it, two and a half or
three feet wide, and six and a half feet high, and board up the inner
partition sides of this opening, so as to form a door-casing on each
side, that the space between the two lines of posts may be a continuous
box all around. Then fill up this space between the posts with moist
tan-bark, or saw-dust, well packed from the ground up to the plates; and
the body of the house is inclosed, sun-proof, and air-proof, to guard
the ice.

Now lay down, inside the building, some sticks--not much matter what, so
that they be level--and on them lay loose planks or boards, for a floor.
Cover this floor with a coating of straw, a foot thick, and it is ready
to receive the ice.

For the roof, take common 3x4 joists, as rafters; or, in place of them,
poles from the woods, long enough, in a pitch of full 35deg from a
horizontal line, to carry the roof at least four feet over the outside
of the plates, and secure the rafters well, by pins or spikes, to them.
Then board over and shingle it, leaving a small aperture at the top,
through which run a small pipe, say eight inches in diameter--a
stove-crock will do--for a ventilator. Then set in, 4 little posts, say
two feet high--as in the design--throw a little four-sided, pointed cap
on to the top of these posts, and the roof is done. If you want to
ornament the under side of the roof, in a rude way--and we would advise
it--take some pieces of 3x4 scantling, such as were used for the roof,
if the posts are of sawed stuff--if not, rough limbs of trees from the
woods, to match the rough posts of the same kind, and fasten them to the
posts and the under side of the roof, by way of brackets, as shown in
the design.
