The Willow Floor
The walls of the cache pit were left bare for the grass lining; but a floor was laid on the bottom. This was rather simply made by gathering dead and dry willow sticks, and laying them evenly and snugly over the bottom of the pit.
The Grass Lining
Over this willow floor, the grass, now thoroughly dried, was spread evenly, to a depth of about four inches. Grass was then spread over the walls to a depth of three or four inches, and stayed in place with about eight willow sticks. These were placed vertically against the walls and nailed in place with wooden pins made each from the fork of a dead willow, as shown in [figure 27]. The ends of the sticks should reach to the neck of the cache pit, at the place marked B, in diagram ([figure 25, page 87]).
We were careful to spread the grass lining evenly over the walls; and we were especially careful not to let the root ends get matted together, as they were very apt to do.
It will be noticed that the willow flooring of the pit, the willow staying rods, and the wooden pins that held them in place, were all made of dead and dry willows; this was done that everything within the pit might be perfectly dry.
It did not take long to place the grass lining of the cache pit.
