198 THE LIVING ANIMALS OF THE WORLD 



tail a horse, in fact, almost identical with the above-mentioned tarpan. But long before 

 historic records begin these horses must have been domesticated ; man discovered that they 

 could be even more useful alive than dead, and from that time forth the horse became his 

 inseparable companion. " Caesar found the Ancient Britons and Germans using war-chariots 

 drawn by horses." 



But the stock of domestic horses drawn from this tarpan breed appears to have died 

 out almost entirely, the majority of horses now existing being probably descendants of the 

 native wild horses of Asia, the product of a still earlier domestication. In Egypt the horse, 

 as a domestic animal, seems to have been preceded by the ass; but about 1900 B.C. it 

 begins to appear in the r6le of a war-horse, to draw chariots. Its use, indeed, until the 

 Middle Ages was almost universally as a war-horse. 



From the time of its domestication till to-day the history of the horse has been one 

 of progress. The care and forethought of the breeder have produced many varieties, resulting 

 in such extremes as the London Dray-horse, the Racer, and the Shetland Pony. 



The coloration of our various breeds of horses is generally without any definite marking 

 piebald and dappled being the nearest approach to a pattern. Occasionally, however, horses are 



found with a dark 

 stripe along the back, 

 and sometimes with 

 dark stripes on the 

 shoulders and legs. 

 Darwin, discovering 

 a number of horses so 

 marked belonging to 

 different breeds, came 

 to the conclusion that 

 probably all existing 

 races of horses were 

 descended from a 

 "single dun-coloured, 

 more or less striped 

 primitive stock, to 

 which [stock] our 

 horses occasionally 

 revert." 



YEARLING ARAB COLTS 



Note the colts examining the photographer* i bag. They are very inquhhi-ve creatures, tut easily frightened 



" If we were not 



so habituated to the sight of the horse," says the late Sir William Flower, "as hardly ever 

 to consider its structure, we should greatly marvel at being told of a mammal so strangely 

 constructed that it had but a single toe on each extremity, on the end of the nail of 

 which it walked or galloped. Such a conformation is without parallel in the vertebrate series." 



By the aid of fossils we can trace out all the stages through which this wonderful foot has 

 , . . . 



in arriving at its present state of perfection : we can see how it has become more 



and more beautifully adapted to fulfil the requirement demanded a firm support to enable 

 its owner to cover hard ground at great speed. The study of the structure of this foot, and a 

 comparison with the intermediate forms, make it clear that this toe corresponds to the third 

 finger or toe of the human hand or foot according as we compare the fore or hind limbs 

 and that its development was at the expense of the remaining toes, which gradually dvvindledj 

 and disappeared, leaving in the living one-toed horse only traces of the second and fourth toes 

 in the shape of a pair of splint-bones, one on either side of the excessively developed third toe. j 



The horses, it must be remarked, may be distinguished from the asses by the fact that the 

 tail m the former is clothed with long hair throughout; in the latter long hair springs only 

 from the sides and end, forming a tuft. Furthermore, the horses have a remarkable horny
