For military purposes its efficiency has been thus substantiated by General Miller in his history of 'The War for Independence':—
"Our corps consisted of ten six-pounders and one howitzer. Each gun was drawn by four horses, and each horse ridden by a gunner, there being no corps of drivers in the service. A non-commissioned officer and seven drivers were, besides the four already mentioned, attached to each piece of artillery. Buckles, collars, cruppers, and breast-plates were not in use; the horses simply drew from the saddle, and with this equipment our guns have travelled nearly 100 miles in a day."
But besides its efficiency for all the requirements of either peace or war, the singular advantage of this simple harness is that any description of horse, tame or wild, uses it without noticing it; for if the single trace which passes immediately beneath his hip bone happens (which it ought not) to press against his side, by shrinking from it only an inch it instantly ceases to touch him; and as there then remains nothing to confine, tickle, or alarm him, he refrains from kicking, simply because there is nothing to kick at, and from quarrelling because he can see nothing in the world to quarrel with.
With this equipment, if a party of native riders, hunting ostriches in South America, are requested to help the horses of a carriage across a river, and up a steep bank, similar, for instance, to that of the Alma, in a moment they affix their lassos, conquer the difficulty, attain the summit, and then, with tobacco smoke steaming from their mouths, gallop away to follow their sport.
The Royal Engineer Train have demonstrated by public experiments in this country, that with this simple equipment, which would injure neither the efficiency nor the appearance of the cavalry, any number of horses, whether accustomed to draught or not, are capable of being at once harnessed to any description of carriage, not only (see sketch) in front to draw it forward, but in rear to hold it back, or even sideways to prevent its oversetting—in short, that it is a power which can be made to radiate in any direction; and as its character stands upon a much firmer foundation—as it is bonâ fide the common mode of draught in South America— in constant use for all military and civil purposes—a practical invention which, under all circumstances, has been always found to answer, it is evident to demonstration,—1st. That if it can transport artillery, &c., across the lofty, vast, and rugged features of uncultivated America, it would surely be serviceable on the roads and bridges of civilized countries. 2ndly, That if it can be adapted to unbroken horses, it cannot be inapplicable to the trained horses of our cavalry. And, 3rdly, That as both the surcingle and trace are made, in America, of nothing but the skins of bullocks, we should, on active service, be able in all countries at least to obtain this material, and generally many others.
It must, moreover, be observed, that as a mounted horse (i. e. a horse and man) are heavier than an unmounted horse, the former with a lasso can drag a heavier weight than the latter with a collar and traces.[L]
Now, supposing for a moment that not only our cavalry were to be furnished with, but that every saddle-horse receiving rations in a European army was to be ordered to wear the South American surcingle (which costs less than English girths and surcingle, and which experience has proved to be, merely as a girth, superior to a common one), and to carry a halter of the usual regulation length, but long enough for a single trace, without detailing the various important as well as trifling services which might be performed, is it not evident that the general activity of the army would most materially be increased? that, in fact, this equipment would form an era in military warfare? that it would be an enormous, and, in Europe, an unheard-of engine of say twenty or thirty thousand horses' power, which, at a moment's warning, could either be called forward or dismissed, and, after all, maintained at no expense whatever? for it must ever be kept in mind, that we possess, and always have possessed, the power; all that, for five and thirty years, we have until lately in vain proposed, is—to rouse it into action.
If the propriety and future utility of this project should be admitted, there is one most important observation to be made. The characteristic feature of this simple harness is, that having been invented for unbroken horses, it possesses the singular military advantage of being at once applicable to any sort or description of horse. But it is well known to every reflecting mind, that there is no useful art which does not, somewhere or other, require attention; and to this general rule the American harness is certainly no exception; for though any horse will draw in it, yet it does require, on the part of the rider, considerable experience and attention. The single trace must be managed in a particular manner, or, in turning, it gets under the horse's tail: unless it is properly held in the hand at starting, the horse may break it by the jerk. There are several other little precautions necessary, most particularly in the mode of adjusting the surcingle, which requires considerable practice and attention.
The many curious and indeed scientific applications and combinations of power of which this simple harness is capable, form a beautiful example of what even uncivilised man can contrive when his attention has been long and steadily directed to a solitary object. And surely the ingenuity and practical experience of one nation are worthy the patient attention of another. But the apparent simplicity of many a useful invention has often been its ruin; and this observation is most particularly applicable to lasso harness, which is, in appearance, so very simple, that it seems to require only to be seen to be perfectly understood: yet, efficient as it is in America, and efficient as it will be to any nation in Europe that will give to its merits sufficient time and a fair trial,—yet, on some little experience and reflection, it is most confidently stated that, as a theory, it certainly is of no use at all; and the truth of this observation will at once be proved by the complete failure and confusion which will inevitably take place if our cavalry try the harness without first not only patiently but cordially and zealously learning how to use it. Yet this ought not, in common justice, to condemn the principle; for, could cavalry, without some little instruction, succeed in driving even with our own harness?—Could French coachmen, without practice, drive our mails?—Could our English postilions drive the five horses of a French diligence? And if driving is thus a science of many departments, it would not be reasonable to expect that our cavalry should be able to drive, merely because they have learnt to ride.
[K] To the 12-pounder Armstrong gun (which sighted to 8° gives a range of 3000 yards) are now attached eight horses in harness, and eight more on which the non-commissioned officers and men, including horse holders, are mounted. Of these, four are supplied with web breast harness and traces: to a proportion of the remainder lassos are supplied.
