In constructing a stable the main object should be to secure to the lungs of the horse pure air, and to prevent the hay in the loft above him from being impaired by foul air.[F]
By a simple shaft or chimney, and by other well-known modes of ventilation, both these advantages can be obtained; and yet they are, comparatively speaking, of no avail, if beneath the straw bed on which the horse lies there exists a substratum generating and emitting gases of a highly deleterious composition.
A stable may be well ventilated and well drained, the forage may be of the best description, and yet all may be impaired by an atmosphere unfit for respiration; for if foul litter beneath be only covered, as is often, and in many stables is usually the case, by a layer of white straw, (like a dirty shirt under a suit of fine new clothing), distemper and disease must be the result.
Although therefore it should be the secondary duty of a good groom to clean his _horse_, his primary duty is to clean _his stable_; for as, in a fast and long run across a deep country, it is undeniable that the healthiest lungs must triumph, it follows that a clean horse out of a dirty stable cannot live with a dirty one of exactly the same character and cast out of a clean stable.
But as it is always easier to preach wisdom than to practise it, so is it infinitely easier to prescribe clean litter than to maintain it. Indeed, it is almost impossible to keep straw under a horse perfectly pure; and accordingly, throughout the United States of America, and even in New York, horses are often made to lie on bare boards, on which they appear to sleep just as soundly as in a state of nature they would sleep on ground baked hard by the sun.
On this fact being privately whispered by us to the authorities at the Horse Guards, it was at once repudiated by the assertion that it would ruin English cavalry horses were they to be made to sleep without litter on hard boards; and yet all the soldiers of Europe, cavalry as well as infantry, in their guard rooms sleep and snore on wooden beds, probably a good deal sounder than do their respective sovereigns on bedding composed of wool, hair, down, feathers, fine linen, blankets, and counterpanes.
