Four forked sticks, driven
into the ground as uprights to support two parallel poles, crossed with
bars will form a framework about three feet high; the fire is beneath.
All fish and flesh is thus preserved by the natives when hunting.
Salt. - When efflorescent on the surface of the soil, scrape with a spoon
or shell, and collect it with as little sand as possible. Cut a hole two
inches square in the bottom of a large earthen pot, cover the hole with
a little straw, then fill the pot with the salt and sand. Pour water
slowly over this, and allow it to filter into a receiver below. Boil the
product until the water has evaporated, then spread the wet salt upon a
cloth to dry in the sun.
Potash. - If you have no salt, treat wood ashes or those of grass in the
same way.
Oil. - All seeds or nuts that will produce oil should be first roasted
like coffee, then ground fine upon a flat stone, and boiled with water.
The oil then rises to the surface, and is skimmed off. Unless the nuts
or seeds are roasted, the boiling water will not extract the oil.
Crutches. - To make impromptu crutches to assist wounded men upon a
march, select straight branches that grow with a fork.
