the gambrel, and short from the gambrel to the ground is also one of 

 the best indications of speed. We see an example in the form of the 

 rabbit and greyhonnd. Bj- a close and constant attention to the anato- 

 mical conformation of a horse, a person may soon become a better judo-e 

 ■of capability in the horse than any one can, who does not take into con- 

 sideration the important facts that all animal mechanism is upon the same 

 principle — that the weight to be moved, and the facility with which it is 

 moved, depends upon the length of the lever and its advantageous liosition, 

 and the consequent length of the muscles, which are the pulleys, and by 

 their action, contraction, and extension, propel the animal over the 

 ground. The most careless observer has probably noticed a trotting horse 

 beaten by one of much less muscle, the reason of which is, the want of 

 a good anatomical form in the muscular horse ; for muscle is not only 

 necessary for rapid and long continued action, but it is equally necessary 

 that it should act advantageously by a proper arrangement and length 

 of particular parts of the animal. These can be best learned by those 

 who are desirous of information on these subjects, by the attentive study 

 of works on the anatomy and physiology of the horse ; William Youatt's 

 is probably the best. All animal mechanism being constructed upon 

 the same principles, intelligent physicians should be, and in general are, 

 excellent judges of the capability of horses, from two causes : their 

 knowledge of anatomy, and their habitual use of the horse in the practice 

 of their profession. 



That speed adds to, and often constitutes the sole value of the horse, 

 in the estimation of many, is well known. An instance now occurs to 

 me: Mr. S. B. Davis, of Milwaukee, took to the. New York market last 

 May, a number of horses ; among which were one pair, which he sold 

 for $1,200, and a single horse which he sold for 8600. They could all 

 trot their mile in about three minutes ; and to this fact can be entirely 

 attributed all he realized on them, over $200 each. There is always a 

 market for well broken horses of good size and good age, if they can go 

 in three minutes or less. Another instance, too, is in point : Jack Ros- 

 siter, the celebrated trotting horse, worked in an omnibus in Milwaukee, 

 and could then have been bought for $200, and probably for less. Fall- 

 ing into the hands of a horseman, he trotted a mile in 2 m. 32 s., and 

 sold for $2,000. Lady Jane, a western mare, was bought in Chicago 

 for $100; she was afterwards sold for $1,600 at a dozen years of age. 

 There are numberless examples of a similar nature. The farmer should
