Straw or Reed Walls of the following kind are very effective, and they have the advantage of requiring a minimum of string (or substitute for string) in their manufacture. The straw, reeds, or herbage, of almost any description, is simply nipped between two pairs of long sticks, which are respectively tied together at their ends, and at a sufficient number of intermediate places. The whole is neatly squared and trimmed.
A few of these would give good help in finishing the roof or walls of a house. They can be made moveable, so as to suit the wind, shade, and aspect. Even the hut door can be made on this principle. In reedy countries where there are no sticks, thin faggots of reeds are used in their place.
Bark.--Bark is universally used in Australia for roofs of huts and temporary buildings; the colonists learnt the use of it from the natives, and some trees, at least, in every forest-country might very probably be found as well fitted for that purpose as those in Australia. The bark may be easily removed, only when the sap is well up in the tree, but a skilful person will manage to procure bark at all seasons of the year, except in the coldest winter months; and even then he will light on some tree, from the sunny side of which he can strip broad pieces. The process of bark-stripping is simply to cut two rings right round the tree (usually from 6 to 9 feet apart), and one vertical slit to join them; starting from the slit, and chipping away step by step on either side, the whole cylinder of bark is removed. The larger the tree, the better; for if the tree is less than 18 inches, or so, in diameter, the bark is apt to break when flattened out. When stripped for huts, it is laid on the ground for some days to dry, being flattened out on its face, and a few stones or logs put on it. the ordinary bark of gum-trees is about half an inch to three-eighths thick, so that a large sheet is very heavy. Most exploring expeditions are accompanied by a black, whose dexterity in stripping bark for a wet night is invaluable, as if the bark will "come off" well, he can procure enough of it in an hour's time to make a shelter for a large party.
Mats can be woven with ease when there is abundance of string, or some equivalent for it (see "String"), in the following manner:--
A, B, are two pegs driven into the ground and standing about a foot out of it. A stake, A B, is lashed across them; a row of pegs, E, are driven into the ground, parallel to A, B, and about 6 inches apart. Two sets of strings are then tied to A B; one set are fastened by their loose ends into clefts, in the pegs E, and the other set are fastened to the stick, C D. If there be ten strings in all, then 1, 3, 5, 7, 9, are tied to C D, and 2, 4, 6, 8, 10, to A B. By alternately raising and depressing C D, and by pushing in a handful of rushes between the two sets of strings after each of its movements, and, finally, by patting them home with a flat stick, this rough sort of weaving is carried on very successfully. Mats are also plaited in breadths, and the breadths are stitched together, side by side. Or a thicker kind of mat may be made by taking a wisp of straw and working it in the same way in which straw beehives are constructed. Straw is worked more easily after being damped and beaten with a mallet.
Malay hitch.--I know no better name for the wonderfully simple way (shown in the figure) of attaching together wisps of straw, rods, laths, reeds, planks, poles, or anything of the kind, into a secure and flexible mat; the sails used in the far East are made in this way, and the moveable decks of vessels are made of bamboos, joined together with a similar but rather more complicated stitch.
I may remark that soldiers might be trained to a great deal of hutting practice in a very inexpensive way, if they were drilled at putting together huts, whose roofs and walls were made of planks lashed together by this simple hitch, and whose supports were short scaffolding poles planted in deep holes, dug, as explained in the chapter on "Wells," with the hand and a small stick. The poles, planks, and cords might be used over and over again for an indefinite time. Further, bedsteads could be made in a similar way, by short cross-planks lashed together, and resting on a framework of horizontal poles, lashed to uprights planted in the ground. The soldier's bedding would not be injured by being used on these bedsteads, as much as if it were laid on the bare ground. Kinds of designs and experiments in hutting could be practised without expense in this simple way.
