This deposit contains a bitter salt in addition, probably the nitrate of lime; the natives, in order to render it palatable and wholesome, mix the salt with the juice of a gummy plant, then place it in the sand and bake it by making a fire over it; the lime then becomes insoluble and tasteless.
The Bamangwato keep large flocks of sheep and goats at various spots on this side of the Desert.

They thrive wonderfully well wherever salt and bushes are to be found.

The milk of goats does not coagulate with facility, like that of cows, on account of its richness; but the natives have discovered that the infusion of the fruit of a solanaceous plant, Toluane, quickly produces the effect.

The Bechuanas put their milk into sacks made of untanned hide, with the hair taken off.

Hung in the sun, it soon coagulates; the whey is then drawn off by a plug at the bottom, and fresh milk added, until the sack is full of a thick, sour curd, which, when one becomes used to it, is delicious.
