Dry Cattle-dung.--The dry dung of cattle and other animals, as found on the ground, is very generally used throughout the world, in default of better fuel, and there is nothing whatever objectionable in employing it. The Canadians call it by the apt name of "Bois de Vache." In North and South Africa it is frequently used; throughout a large part of Armenia and of Thibet the natives rely entirely upon it. There is a great convenience in this sort of fuel; because, as it is only in camps that fuel is wanted, so it is precisely at old encamping-places that cattle-dung is abundantly found.
Bones.--Another remarkable substitute for firewood is bones; a fact which Mr. Darwin was, I believe, the first to mention. The bones of an animal, when freshly killed, make good fuel; and even those of cooked meat, and such as have been exposed to the air for some days, will greatly increase the heat of a scanty fire. Their smell is not disagreeable: it is simply that of roast or burnt meat. In the Falkland Islands, where firewood is scarce, it is not unusual to cook part of the meat of a slaughtered bull with its own bones. When the fire is once started with a few sticks, it burns well and hotly. The flame of course depends on the fat within the bones, and therefore the fatter the animal the better the fire. During the Russian campaign in 1829, the troops suffered so severely from cold at Adrianople, that the cemeteries were ransacked for bones for fuel. (Moltke, in the Appendix.)
Sea-weed makes a hot though not a cheerful fire. It is largely used. The vraic or sea-weed gatherers of the Channel Islands are represented in many picturesque sketches. The weed is carted home, spread out, and dried.
Peat.--Travellers must bear in mind that peat will burn, especially as the countries in which it is found are commonly destitute of firewood; and, besides that, are marshy, cold, and aguish.
Charcoal is frequently carried by travellers in sacks; they use a prepared charcoal in the East, which is made in the form of very large buttons, that are carried strung together on a string. An Indian correspondent informs me that they are made by mixing powdered charcoal with molasses, in the proportion of ten to one, or thereabouts, rolling the mass into balls, and drying them in the sun. A single ball is called a "gul." They are used for igniting hookhas: they are also burnt inside the smoothing-iron used by washermen in order to heat it. The juice or sap of many plants would probably answer the purpose of molasses in their preparation.
Small Fuel for lighting the Fire.--Shreds and Fibres.--The live spark has to be received and partly enclosed, in a loose heap or nest of finely-shredded fuel. The substances for making such a nest, are one or other of the following list:--
Dry grass of the finest kinds: leaves: moss: lichen, and wild cotton; stalks or bark, broken up and rubbed small between the fingers; peat or cattle-dung pulverised; paper that has been doubled up in many folds and then cut with a sharp knife into the finest possible shavings; tow, or what is the same thing, oakum, made by unravelling rope or string; and scrapings and fine shavings from a log of wood. The shreds that are intended to touch the live spark should be reduced to the finest fibre; the outside of the nest may be of coarser, but still of somewhat delicate material.
Cook should collect them.--It is the duty of a cook, when the time of encamping draws near, to get down from his horse, and to pick up, as he walks along, a sufficiency of dry grass, little bits of wood, and the like, to start a fire; which he should begin to make as soon as ever the caravan stops. The fire ought to be burning, and the kettle standing by its side, by the time that the animals are caught and are ready to be off-packed.
Small Sticks.--There should be abundance of small sticks, and if neither these nor any equivalent for them are to be picked up, the traveller should split up his larger firewood with his knife, in order to make them. It is a wise economy of time and patience to prepare plenty of these; otherwise it will occasionally happen that the whole stock will be consumed and no fire made. Then the traveller must recommence the work from the very beginning, under the disadvantage of increasing darkness. I have made many experiments myself, and have seen many novices as well as old campaigners try to make fires; and have concluded that, to ensure success, the traveller should be provided with small bundles of sticks of each of the following sizes:--1st, size of lucifer-match; 2nd, of lead pencil; 3rd, smaller than little finger; 4th, size of fore-finger; 5th, stout stakes.
In wet Weather, the most likely places to find wherewithal to light a fire, are under large stones and other shelter; but in soaking wet weather, little chips of dry wood can hardly be procured except by cutting them with an axe out of the middle of a log. The fire may then be begun, as the late Admiral the Hon. C. Murray well recommended in his travels in North America, in the frying-pan itself, for want of a dry piece of ground.
