Dry Dung.-Dry and powdered cattle dung-especially horse-dung-will take a spark, but with trouble. After it is lighted it can be kept burning with little difficulty.
Tinder-boxes.-There are three ways of striking a flint, which are best explained by sketches. Fig. 1, p. 180, shows how tinder that is tough enough to bear handling, is grasped together with the flint. When no tinder-box is at hand the more friable kinds of tinder, as touch-wood, may be enveloped
in a roll of rag and be used either as in fig. 1 or in fig. 3. Fig. 2 shows how tinder may be laid on the ground, and how sparks may be struck upon it. The household tinder-boxes of thirty years ago, before lucifers were invented, were for use in this way. Fig. 3 shows how sparks may be struck into a small tinder-box. It is the method most commonly adopted by travellers : for instance, it is universally used in South Africa and in North America. A hollow cylinder of wood or metal, about three inches long, and corked up at one end, is all that is essential. If it be barrel-shaped the flint lies against its sides, at the most convenient angle for striking sparks into the box, as is shown by the bottom drawing of fig. 3.
Wet Weather.-In long-continued soaking weather, the best way of keeping a tinder-box dry is to put it into a small pocket hung close under the armpit.
