The shape and size of the hole corresponds to that of the roof it may be possible to procure for it; its depth is no greater than requisite for sitting or standing. If the roof has a pitch of 2 feet in the middle, the depth of the hole need not exceed 4 1/2 feet. In the Crimea, the holes were rectangular, and were roofed like huts.
Where there is a steep hillside, a a', fig. 2, an underground hut, b, is easily contrived; because branches laid over its top, along the surface of the ground, have sufficient pitch to throw off the rain. Of course the earth must be removed from a', at the place intended for the doorway.
Reed Huts.--The reed huts of the Affej Arabs, and other inhabitants of the Chaldean marshes, are shaped like wagon-roofs, and are constructed of semicircular ribs of reeds, planted in the ground, one behind the other, at equal distances apart; each rib being a faggot of reeds of 2 feet in diameter. For strength, they are bound round every yard with twisted bands of reeds. When this framework has been erected, it is covered with two or three sheets of fine reed matting (see "Matting"), which forms a dwelling impervious to rain. Some of the chiefs' huts are as much as 40 feet long, and 12 high; the other huts are considerably smaller. Many of these reed dwellings are contained in compounds enclosed by lofty reed fences; the reeds being planted upright, and simply strung together by a thread run through them, as they stand side by side. (See "Straw and Reed Walls.")
Snow-houses.--Few travellers have habitually made snow-houses, except Sir J. Franklin's party and that of Dr. Rae. Great praises are bestowed on their comfort by all travellers, but skill and practice are required in building them. The mode of erection of these dome-shaped buildings is as follows:--It is to be understood that compact, underlying snow is necessary for the floor of the hut; and that the looser textured, upper layer of snow, is used to build the house. First, select and mark out the circular plot on which the hut is to be raised. Then, cut out of that plot, with knives, deep slices of snow, 6 inches wide, 3 feet long, and of a depth equal to that of the layer of loose snow, say one or two feet. These slices are to be of a curved shape, so as to form a circular ring when placed on their edges, and of a suitable radius for the first row of snow-bricks. Other slices are cut on the same principle for the succeeding rows; but when the domed roof has to be made, the snow-bricks must be cut with the necessary double curvature. A conical plug fills up the centre of the dome. Loose snow is next heaped over the house, to fill up crevices. Lastly a doorway is cut out with knives; also a window, which is glazed with a sheet of the purest ice at hand. For inside accommodation there should be a pillar or two of snow to support the lamps.
Snow Walls with Tenting for their Roofs.--Sir L. McClintock says:--"We travelled each day until dusk, and then were occupied for a couple of hours in building our snow-hut. The four walls were run up until 5 1/2 feet high, inclining inwards as much as possible, over these our tent was laid to form a roof. We could not afford the time necessary to construct a dome of snow. Our equipment consisted of a very small brown-holland tent, macintosh floor-cloth and felt robes; besides this, each man had a bag of double blanketing, and a pair of fur boots, to sleep in. We wore mocassins over the pieces of blanketing in which our feet were wrapped up, and, with the exception of a change of this foot-gear, carried no spare clothes.
"When we halted for the night, Thompson and I usually sawed out the blocks of compact snow, and carried them to Petersen, who acted as the master-mason in building the hut. The hour-and-a-half or two hours usually employed in erecting the edifice was the most disagreeable part of the day's labour; for, in addition to being already well tired and desiring repose, we became thoroughly chilled while standing about. The dogs were then fed, then the sledge unpacked, and everything carried into it. The door was now blocked up with snow, the cooking-lamp lighted, foot-gear changed, diary writing up, watches wound, sleeping-bags wriggled into, pipes lighted, and the merits of the various dogs discussed, until supper was ready; the supper swallowed, the upper robe or coverlet pulled over, and then to sleep. Next morning came breakfast, a struggle to get into frozen mocassins, after which the sledges were packed, and another day's march commenced. In these little huts we usually slept warm enough, although latterly, when our blankets and clothes became loaded with ice, we felt the cold severely. When our low doorway was carefully blocked up with snow, and the cooking-lamp alight, the temperature quickly rose, so that the walls became glazed and our bedding thawed; but the cooking over, or the doorway partially opened, it as quickly fell again, so that it was impossible to sleep, or even to hold one's pannikin of tea without putting mits on, so intense was the cold."--Sir L. McClintock is here speaking of a temperature of -39 degrees Fahr.
Materials for building Huts.--The materials whence the walls and roofs of huts may be constructed are very numerous: there is hardly any place which does not furnish one or other of them. Those principally in use are as follows:--
Wattle-and-daub, to be executed neatly, required well-shaped and flexible sticks; but a hut may be constructed much like the sketch (see p. 120) of the way of "Drying Clothes." It is made by planting in the ground a number of bare sticks, 4 feet long, and 1 foot apart, bending their tops together, lashing them fast with string or strips of bark, and wattling them judiciously here and there, by means of other boughs, laid horizontally. Then, by heaping leaves--and especially broad pieces of bark, if you can get them--over all, and banking up the earth on either side, pretty high, an excellent kennel is made. If daubed over with mud, clay, or cattle-dung, the hut becomes more secure against the weather. To proceed a step further:--as many poles may be planted in the ground as sticks have been employed in making the roof; and then the roof may be lifted bodily in the air, and lashed to the top of the poles, each stick to its corresponding pole. This sort of structure is very common among savages.
For methods of digging holes in which to plant the hut-poles, see the chapter on "Wells." The holes made in the way I have there explained are far better than those dug with spades; for they disturb no more of the hardened ground than is necessary for the insertion of the palisades. To jam a pole tightly in its place, wedges of wood should be driven in at its side, and earth rammed down between the wedges.
Palisades are excellent as walls or as enclosures. They are erected of vast lengths, by savages wholly destitute of tools, both for the purposes of fortification and also for completing lines of pitfalls across wide valleys. the pitfalls occupy gaps left in the palisading. The savages burn down the trees in the following manner:--a party of men go to the forest, and light small fires round the roots of the trees they propose to fell. the fires are prevented from flaming upwards by the judicious application of leaves, etc. When the fire has eaten a little way into the tree, the man who watches it scrapes the fire aside and knocks away the charred wood, exposing a fresh surface for fire to act upon, and then replaces the burning embers. A single man may easily attend to a dozen trees, and, indeed, to many more, if the night be calm. Some hours elapse before the trees actually fall. Their tops and branches are burnt off as they lie on the ground. The poles being thus procured for the palisading, they are carried to the required place, where holes are dug for their reception, on the principle described in "Wells," to which I have just alluded.
