The animal formerly in use cost from 30_l._ to 50_l._-- Two hundred guineas is now an every-day price for a cabriolet horse; and 150 guineas for a coach-horse, for a private gentleman’s work. A pair of handsome coach-horses, fit for London, and well broken and bitted, cannot be purchased under 200 guineas; and even job-masters often give much more for them to let out to their customers. The origin of this superior kind of coach-horse is still, however, the Cleveland bay, confined principally to Yorkshire and Durham, with perhaps Lincolnshire on one side, and Northumberland on the other, but difficult to be met with pure in either county. Cleveland indeed, and the Vale of Pickering, in the East Riding of Yorkshire, are the best breeding counties in England for coach-horses, hunters, and hackneys. When the Cleveland mare is crossed by a three-fourth or thorough-bred horse of sufficient substance and height, the produce is the coach-horse most in repute, with his arched crest and high action. From the same mare and the thorough-bred of sufficient height, but not of so much substance, we obtain the four-in-hand, and superior curricle horse. From less height and more substance, we derive the hunter, and better sort of hackney. From the half-bred, we have the machiner, the poster, and the common carriage-horse. The best coach-horse is a tall, strong, over-sized hunter. The hackney has many of the qualities of the hunter on a small scale. There is some deception, however, even as to the best of these improved coach-horses. They prance nobly through the streets, and they are capable of more work than the old clumsy, sluggish breed, but still they have not the endurance that is desirable; and a pair of poor post-horses, at the end of the second day, would beat them hollow. In this carriage-horse, the bending of the upper joints, and the consequent high lifting of the feet, are deemed an excellence, because they add to the grandeur of his appearance; but this is necessarily accompanied by much wear and tear of the legs and feet, the effect of which is very soon apparent. The most desirable points in the coach-horse are--substance well placed, a deep and well-proportioned body, bone under the knee, and sound, open, tough feet.
