CHAPTER VI.
Hints on the Construction of Tents and on Camp Sanitation.
In many hot countries Europeans of all classes pass a considerable portion of their time under canvas, and though it is not proposed to refer in any way to military operations, some reference to the management of small private camps is desirable.
In pioneering life in the colonies, permanent encampments necessarily have to serve in place of houses, often for long periods, and in such colonies as South Africa whole families are often “on the trek” for months together; whilst in India most officials must pass much of the cold season under canvas as a part of their routine duty, and it is quite common for an official to be accompanied on these long tours by his family and entire establishment.
Now in spite of its apparent inconveniences, tent-life is, if fairly well managed, extremely healthy, and there can be no doubt that in India these cold weather tours under canvas form the saving clause in the description of an official’s life; so that it is extremely desirable that, wherever practicable, the ladies and children of a family should share in its advantages. In a well-ordered Indian cold weather tour in tents, the hardships are indeed so purely nominal that there is no difficulty whatever in taking even the youngest children, not only without any increase in the risks of life, but with enormous advantage to health.
Tents should, as a rule, be obtained on the spot, as those manufactured in any given country will generally be better planned to meet special local exigencies than those obtainable elsewhere, and in any case it is a mistake to obtain an outfit of this description in Europe, as tent-life is so foreign to the habits of settled countries, that our manufacturers are utterly ignorant of the proper plan of construction, or of the most suitable materials to choose. The English service bell-tent, for example, seems contrived to combine all possible disadvantages that a tent can possess, every other consideration being sacrificed to the idea of supporting it by means of a single pole; though the advantages of this are more than neutralised by the employment of a spar, better suited to serve as the mizen-mast of a small cruiser than for the purpose for which it is intended. In India, on the other hand, the manufacture of tents has been an extensive industry for centuries, and the intending explorer or colonist who is likely to have to pass prolonged periods under canvas cannot do better than obtain what he requires from some of the large manufacturers in Cawnpore or Lahore.
In the first place, it may be laid down as an absolute rule, that tents with single “flies” or roofs, are quite unsuitable to any climate, and should never be used except under the absolute compulsion of restricted transport. Such tents are insufferably hot in warm climates, bitterly cold in chilly ones, and damp and unwholesome in rainy weather in either. On the other hand, the use of waterproofed material is, as a rule, a mistake, and should at any rate never be adopted for the inner fly, as to do so would make any tent of moderate dimensions intolerably “stuffy.” In very rainy climates, there might be no harm in selecting light milrained canvas as the material for the outer fly; but there is no real necessity for this, as a tent should be so planned as to throw off the water by virtue of the slope of the roof, and not by the character of its materials.
A second point to be remembered, is that two or more layers of comparatively light material will afford far greater protection against either heat or cold than the same weight of material woven as a single heavy cloth, and on this account the canvas universally used in Europe for work of this sort is absolutely unsuited for the purpose.
Each fly of an Indian tent is usually formed of two or three layers of cloth, the outer layer being formed of what is generally known as “American” cotton drill, though it is usually of local manufacture; and it would be hard to find a material better suited for the purpose. Where only two layers of cloth are used, the inner layer should be a deep red, as this colour cuts off the largest proportion of the chemical rays of the sun, which exercise such a powerful effect on the human economy. With three layers the middle one should be red, and the undermost deep indigo. In the case of the inner fly, for the middle layer of cloth, where there is one, a deep red should also be selected, but the inner lining should be a pale yellow chintz, as a sombre cloth makes a tent uncomfortably dark. The poles should be so constructed that a space of free air, of not less than a foot, should intervene between the two flies, even in the smallest tents, and if the outer fly be properly planned, it should be impossible for rain to reach the inner fly, even under the worst conditions of weather; though this proviso need not extend to verandahs and bath-rooms, which are not intended for prolonged occupation, and so may be formed by the outer fly only. When weight is a serious consideration, as in the case of exploring parties, it would be difficult to find a better form than that known as the “Kabul tent,” which, with poles, mallet and pegs, weighs but 80 lbs., while the somewhat larger “Field Officer’s Kabul,” weighing, with verandah and bath-room complete, 120 lbs., forms about as comfortable a little residence as can be desired for such purposes. For Indian family use, and for permanent encampments, where a tent has to serve in place of a house, the best form is probably that known as the “Swiss Cottage Tent,” which, however, weighs, according to size, from 4 to 6 cwt., and is therefore only useful for a moving camp, where ample wheeled transport is available.
People unaccustomed to living in tents are apt to think that they are necessarily draughty and uncomfortable, but this is so far from being the case that it is quite as necessary to attend to their ventilation as that of a house; and this is especially true of large tents, the gable part of which is rarely sufficiently ventilated to allow of the escape of foul and heated air. All that is provided for this purpose by manufacturers are a few brass eyelet boles, the total area of which is far too small to have any appreciable effect whatever. Those who possess large tents will do well, therefore, to have made in the uppermost part of the gable of the inner fly of a Swiss Cottage, or near the apex of the pyramidal single pole tent, a small window measuring some 8 in. or 10 in. square. It is easy to arrange a curtain for this, capable of being closed with strings from below, but in practice it will be found that it is never necessary to close the opening, which may merely, therefore, be filled in with strong twine netting, so as to maintain the strength of the tent. The gain in coolness effected by this little modification will be astonishing to those who have not tried it, and it is equally necessary where a stove is used for heating a tent.
Having mentioned this point of the warming of tents, it may be well to point out that on no account should the common native plan of using an open charcoal brazier be adopted, as it is quite a mistake to imagine that a tent is not quite capable of sufficiently retaining the poisonous charcoal fumes to cause harmful, and even serious, effects.
