space cleared for it. Then a row of snow blocks is laid on the
ground and another course of similar blocks placed on top. The
snow blocks are not exactly square in shape, but about 12 in.
long, 6 in. high and 4 or 5 in. thick. Larger or smaller blocks
can be used, according to size of the house and thickness of the
walls.

First, the snow blocks must be packed and pressed firmly into
position out of moist snow that will pack. A very light, dry snow
will not pack easily, and it may be necessary to use a little
water. If the snow is of the right consistency, there will be no
trouble in packing and working with it. As most of the blocks are
to be of the same size throughout, it will pay to make a mold for
them by forming a box of old boards nailed together, minus the
top, and with a movable bottom, or rather no bottom at all. Place
the four sided box on a flat board and ram snow in it, forcing it
down closely. Then by lifting the box up and tapping the box from
above, the block will drop out. In this way blocks of uniform size
are formed, which makes the building simpler and easier.

While one boy makes the blocks another can shave them off at the
edges and two others can build the house, one inside of the circle
and the other outside. The Eskimos build their snow houses in this
way, and the man inside stays there until he is completely walled
in. Then the door and a window are cut through the wall.
