The explorer traversing a hitherto unknown country, the soldier engaged in a campaign, the hunter, the trader, and the settler in the borderlands of civilisation, have every day and sometimes every hour to supply by their own ingenuity needs which for us are satisfied by the simple expedient of sending to a well-stocked shop for what we require, or calling in a skilled workman to do a job for us. Accustomed as we have been all our lives to procuring our bread and meat from the baker and butcher, sleeping every night in comfortable bedrooms, trusting for protection to 'Policeman X' and his brethren of the blue coat and helmet, and making our journey by rail at fifty miles an hour—we can hardly realise the position of a man who is thrown on his own resources for food and shelter in a wild country, where perhaps his road lies over scorched plains or through dense forests. Yet if he only knows how to set about it, such a man can live and travel or do his work in comparative safety and comfort. Even on his own ground the uncivilised is inferior to the civilised man, for the latter has learned or can learn from the savage all that is most useful in a wild country, and can add this local knowledge to the resources which civilisation has placed at his command. His natural physical powers are generally superior to those of an uncultured people, and he can supplement them by aids derived from art. What is the piercing sight of an Indian or an Arab scout to the power of a good field-glass or telescope? And in the chase or the fight the assegai or the flint-lock musket stand but a poor chance against the rifle. Moreover the savage knows only a few shifts or 'dodges' peculiar to his own people; but the explorer has at his command at once the arts of civilisation and those of hundreds of uncivilised tribes. He learns from the Eskimo to traverse the snow on snow-shoes, or make long journeys with the dog-sledge; he takes the canoe of the Indian, and the Malayan outrigger; he can build a half-buried hut like a Tartar, or a palm-leaf cottage like a negro; he learns from the Guacho to stop a wild-horse with the lasso; and in the pursuit of game, the traditional lore of the trappers and hunters of every land is at his service. If he is strong, active, and hardy, and can use a few tools, he can learn in this way a hundred 'shifts and expedients,' either from oral instruction, or from books such as that which lies before us: Shifts and Expedients of Camp Life, Travel, and Exploration. By W. B. Lord, R.A., and T. Baines, F.R.G.S. Field Office. (30s.)

We have seen other works of the same kind, but none so complete as this. To the explorer, the soldier, the settler, and the missionary, it will be invaluable; and even stay-at-home people who lead an active life in the country, will gather many valuable hints from it. To all it will be of interest, on account of its numberless anecdotes of successful struggle with difficulties of every kind, sketches of the arts and customs of uncivilised man, and notes on the topography of many lands and the natural history of their winged and four-footed inhabitants. Here we are told how to set about building a boat of wood or skin; how to make a birch-bark canoe; how to repair a broken axle or wagon-wheel; how to cross a bridgeless river; how to build a hut or pitch a tent; to picket horses and secure camels; to trap wild beasts or snare birds; to find a dinner where there are no shops, and to cook it without a kitchen. These are a few of the many subjects treated by our authors, who are themselves veteran travellers and explorers, and have learned in the field much of the knowledge which they here communicate to others.

It would seem that one of the chief difficulties in organising an exploring expedition is to decide upon the stores and provisions to be carried. If there is not enough of these, the party may be crippled far from its base of operations; if there is too much, its movements will be seriously impeded by the necessity of transport. Much depends upon the nature of the country. One of the Australian expeditions which had to traverse districts where food of all kinds was scarce, had to carry an enormous amount of stores, the first item in the list being seventeen thousand pounds of flour; but then the party consisted of twenty-one men. Generally an explorer is in the best position who can start off with only one or two white followers, the rest of his party being hired natives, well used to the ways of the country; and we believe the most successful explorers have been those who, as far as white men are concerned, have worked alone or almost alone. Livingstone's success is a good proof of this. Mr Lord suggests that in countries where riding is practicable, explorers should make up their minds to eat horse-flesh occasionally, and start with a good train of pack-horses, each horse being shot and eaten as soon as its burden is disposed of. He does not appear to have ever tried the plan himself; and we fear that at the end of a long march the flesh of a hard-worked pack-horse would be a very poor substitute for roast-beef. It is a pity that oxen cannot be used as pack-animals. They are turned to a stranger purpose in South Africa, where the Hottentots and Kaffirs saddle and ride them; and one of the authors of this book of travel tells us that he has more than once had a very comfortable ride on one of these horned steeds.

The Tartars use dogs to carry packs; in the far north they do the chief work in pulling the sledges, though the Laplanders chiefly use the reindeer for this purpose. The Eskimo sledge-dogs are fine strong animals, nearly allied to the wolf; and Messrs Lord and Baines give some amusing hints about their management. The sledge-driver must never leave his sledge without securing it to a spear driven into the snow, or the dogs will perhaps start off of their own accord and distance all pursuit. They are very quarrelsome; but generally in every team there is one master-dog, with a very determined will and strong sharp teeth; and when he sees the others fighting, he will dash in amongst them, and vigorously assist his master in restoring order. When rough ice is to be traversed, the dogs' paws are protected by little bags or moccasins of hide. They are not fed till the day's work is over; and great care has to be taken that each gets his proper share, for 'some are so desperately artful and cunning that they do all in their power to delude their master into a belief that instead of having had their full allowance, it is yet to come.' The Lapland sled or kerres is different from the low flat Eskimo dog-sledge. It is shaped something like a big shoe, and is drawn by the reindeer, which is used in the same way in Siberia, and also for riding and carrying packs. In many countries summer sleds are used. One of the easiest to make is formed of a forked branch, with pieces of wood nailed across the fork, the horse or mule being harnessed to the pointed end. This is often used by the settler for dragging loads of all kinds over level ground.

These forked branches and sticks can be turned to an endless number of uses. Grindstones are mounted between them; they form yokes for hanging weights over the shoulders; hooks for suspending small objects in the hut or tent; racks for arms and harness. In many countries the native plough is formed of two forked branches tied together and dragged by one man, while another holds it down, and thus scratches a furrow in the ground. The frontier settler has sometimes to be content with a similar contrivance, made on a larger scale, of bigger branches, and drawn by a couple of his oxen.

Some of the architectural 'shifts' are very interesting, for there is a wide field for ingenuity in the construction of hut and boat. In the tropics, huts are very easily constructed by building up a framework of poles, branches, or bamboos, the sticks being not nailed but lashed together where they cross; this rough outline of walls and roof is then filled in with mats, bundles of rushes, or the broad leaves of the fan-palm. Another method is to build the hut of slabs ingeniously formed out of a very unpromising material—long reeds. A few sticks are cut and laid parallel to each other on the ground; then across these a thick bed of reeds is carefully arranged; another stick is laid on this bed, exactly over each of the sticks below; the projecting ends of each pair of rods are then tied together; and the solid mass of reeds thus secured can be raised on its lower edge and supported by props or by other slabs meeting it at an angle, much as children build houses of cards. In this way very serviceable stables and outhouses are often made in India. Having erected his light hut or pitched his tent, the traveller, if he is making a prolonged halt, proceeds to furnish it. Planks and boxes supply seats; and if there is a pole in the centre, a serviceable table can be made by fixing a wagon-wheel on it about two and a half feet from the ground, the pole passing through the centre of the wheel, and the spokes being covered with a few small boards. A comfortable bed is easily improvised. Livingstone had a new one made every night under his own supervision. This was his plan. First, he had two straight poles cut, two or three inches in diameter, which were laid parallel to each other at a distance of two feet apart; across these poles were placed short sticks, saplings three feet long; and over these was laid a thick pile of long grass; then came the usual waterproof ground sheet and the blankets. 'Thus,' writes Stanley, 'was improvised a bed fit for a king.' The wagon used by the colonists at the Cape is very like a long hut on wheels, and forms a very comfortable sleeping-place; while a large tent can be made by halting the wagon, driving in a few poles near it, and stretching the tent canvas from these to the wagon-roof. It has been proposed too that this roof should be an inverted boat of waterproof canvas, which could be removed at pleasure and used in crossing rivers. The wagon is so large that this seems to be quite a practicable idea.

Every explorer and traveller must carry some kind of a boat or canoe with him. If he is without one, the natives will often make most extortionate demands for the hire of their own to him; but if he has one, no matter how small, he can bargain on much more equal terms. But even if no boats can be procured, the mere crossing of a river can always be effected by means of rafts. These can be made of almost anything; casks, boxes, planks, reeds, bamboos, all can be pressed into the service; but we are told, it must be borne in mind 'that the cargo a raft can carry above water is always small, and not at all like the mountain of treasure invariably represented on that of Robinson Crusoe.' These rafts are often constructed of very strange materials. On the Nile they are made of jars, which are thus brought down the river to be sold at Cairo. On many of the African rivers they are made of bundles of sedge-grass; and lying down on these, the hippopotamus hunters approach the huge beast; the raft looking so like a natural accumulation that he does not attempt to get out of the way till it is too late. On such a raft, made on a larger scale, the Swedish naturalist Lindholm and his assistant successfully descended one of the rivers that feed Lake Ngami. The voyage was a strange one. The raft was built in a quiet nook by throwing hundreds of bundles of sedge across each other, without any other fastening than their natural cohesion and entanglement. On this huge floating mass a hut was built, and the two adventurers then poled it out into the stream, and it went down the current at the rate of about forty or fifty miles a day. Occasionally it took the ground at the bottom, but when a little of the grass tore off, it floated clear again. As the lower layers became sodden and pressed together, fresh grass had to be cut every day and laid on top, till at last there was six feet of the raft under water. Occasionally overhanging branches tore off some of the grass, and once a large projecting trunk lay so close to the water that it 'swept the decks fore and aft.' The hut was destroyed, and with much of its contents was carried away into the river; but the travellers saved themselves by climbing over the bough, and then repaired the damage and resumed their voyage. Sir Samuel Baker constructed a much more singular raft to cross the Atbara River in Equatorial Africa. A bedstead supported by eight inflated hides formed the basis of the structure; and on this was secured a large sponging bath three feet eight inches in diameter, which formed a dry receptacle for the ammunition and other baggage.

One of the most remarkable features of uncivilised life is the power savages shew of tracking men and beasts over immense distances. Many travellers have spoken of this as something almost miraculous, yet it is only the result of careful observation of certain well-known signs; and we have here before us a collection of very common-sense hints on the subject. In countries like ours every trace of foot-print or wheel-track on roads and paths is soon obliterated or hopelessly confused; but it is otherwise in the wilderness, where neither man nor beast can conceal his track. In Kaffirland, when cattle are stolen, if their foot-prints are traced to a village, the headman is held responsible for them, unless he can shew the same track going out. A wagon-track in a new country is practically indelible. 'More especially,' say our authors, 'is this the case if a fire sweeps over the plain immediately after, or if the wagon passes during or after a prairie fire. We have known a fellow-traveller recognise in this manner the tracks his wagon had made seven years before, the lines of charred stumps crushed short down remaining to indicate the passage of the wheels, though all other impressions had been obliterated by the rank annual growth of grass fully twelve feet high.' Sometimes the original soil being disturbed, a new vegetation will spring up along the wagon-track, and thus mark out the road for miles. Even on hard rock a man's bare foot will leave the dust caked together by perspiration, so that a practised eye will see it; and even if there is no track, a stone will be disturbed here and there, the side of the pebble which has long lain next the ground being turned up. If it is still damp, the man or beast that turned it has passed very recently. If a shower of rain has fallen, the track will tell whether it was made before, during, or after the shower; similar indications can be obtained from the dew; and another indication of the time that has elapsed since a man passed by is furnished by the state of the crushed grass, which will be more or less withered as the time is longer or shorter. Other indications are drawn from the direction in which the grass lies; this tells how the wind was blowing at the time the grass was crushed; and by noting previous changes of the wind, one learns the time at which each part of the track was made. Much too can be learned from the form of the foot-prints. Savages generally turn their toes in, in walking; white men turn theirs out. A moccasin print with the toes turned out would indicate that a white man in Indian walking-gear had gone by; and almost every foot has a print of its own, which enables an experienced tracker to follow a single track amongst a dozen others. Similarly the character of the print will tell whether the man who made it walked freely or was led by others; whether he was in a hurry or travelling slowly; whether he carried a burden; and if he were sober or tipsy. A horse-track is equally well marked. It tells when the horse galloped, where he walked, when he stopped to feed or drink; and a scattering of sand and gravel will tell when he was startled by any strange sight. In all this two things are needed—sharp sight and careful training. The elephant often makes a very curious track as he walks; if he suspects danger, he scents the ground with the tip of his trunk, and this makes a well-marked serpentine line in the dust. Elephants have changed their tactics since rifle-pits were introduced. Formerly, when their chief danger was a pitfall, the leader of the herd felt the ground inch by inch; and if he detected the covering of a trap, tore it off and left it open. Now they rely much more on scent, and in this way, often from a great distance, detect the hunter lurking near their drinking-places. If so, they will sometimes travel fifty or a hundred miles to another stream or pool.—Such is a specimen of this generally amusing book.
