For travellers camping out in South Africa, Nature has provided wonderfully good ovens in the ant-heaps, which are plentiful in this country. Supposing that there was little or no shelter, and, as would be quite natural, great difficulty in lighting fire where wood is scarce, the traveller should halt in the vicinity of an ant-heap. He should make a hole at the side and go on scooping it out until there is a good-sized cavity; then make a hole at the top just large enough to fit a saucepan or kettle on. After collecting some dry grass, set it alight, and place it in the cavity. The inner walls of the ant-heap being mostly composed of fine dry grass, it will soon ignite, and in a very short time the pot or kettle will be boiling. If he wishes to bake a loaf the oven would be found sufficiently hot, the hole at the top having teen filled up with clay, which can be obtained by mixing the stuff taken from the ant-heap with water. If the traveller be halting in a wooded part, an oven may be improvised by scooping a hole in a bank or ravine and heating it with wood. For an improvised stove, travellers should provide themselves with an empty oil-drum - one that would contain six gallons of oil - the top to be cut out, and at about four inches from the bottom, two holes, four inches square, to be made on opposite sides. Lay some wood in the drum, and light the fire, then place the saucepan on the top. This would be found useful in either windy or rainy weather, and has been used by fishermen in open boats at sea. In travelling the oil-drum will form an excellent stowaway for small articles.
