A single opening served as a door. Aboriginal ingenuity could not pass beyond this rude contrivance, so having opened the way for ingress and egress, the builder was content to hang a bison skin as a curtain. This could be readily pulled aside by any one, and the door locked by fastening the corners. Windows are a sinful extravagance to the American Indian, and there was not one in the village to which Jack Carleton was taken. When the open door, the burning fire, the hole which answered for a chimney, and the numerous crevices did not give enough light for the interior, the occupants went outside to obtain it.
