If you wish to make the roof as the cliff-dwellers made theirs, put your
biggest logs crosswise from _A_, _M_, _E_ to _C_, _O_, _G_ of your house
for rafters, and across the larger logs lay a lot of small poles as close
together as may be, running from the back to the front of the house. Fill
in the cracks between with moss or calk them with dry grass; on them
place a layer of brush, browse, or small sticks and over this a thick
coating of clay, hard-pan, or ordinary mud and pack it down hard by
tramping it with your feet until it becomes a smooth and tightly packed
crust; over this you can put your sod and weeds to conceal your secret.
