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. Cut them to the length required, and lash a small piece of wood across the fork. This, if wound with rag, will fit beneath the arm, and make a good crutch.
In this manner I brought my wounded men along on the march from Masindi.
Tamarinds.—Whenever possible, collect this valuable fruit. Take off the shell, and press the tamarinds into lumps of about two pounds. They will keep in this simple form for many months, and are invaluable in cases of fever-cooling when drunk cold, and sudorific when taken hot. If taken in quantity, they are aperient.
