While it might be forcibly, if not conclusively, argued that the native English horse had in him all the elements necessary to the development of a breed of race horses as great as the breed of our own day, there is one fact ever present to the senses which goes to show that the influence of exotic blood was very wide and very powerful in controlling the action of the race horse. The popular and prevailing pacing action of the Hobbies, the Galloways, and other hunting, racing and saddle tribes was completely wiped out more than a hundred years ago. Any attempt to account for this revolution in the gait of the English horse as a fancy of fashion, or on the introduction of wheeled vehicles, fails to satisfy the understanding. In the first half of the seventeenth century pacers were popular, common, and abounded everywhere. In the second half of the eighteenth century not one could be found in all Britain, “from Land’s End to John O’Groat’s House.” Of all the facts that are known and established in the history of the English horse, the wiping out of the pacer is the most striking and significant. This exterminating process was not limited to the families that were intended for hunting or racing purposes, but extended to all types and breeds of English horses. The little English pacers that had been the favorites of kings and princes and nobles for so many centuries were submerged in the streams of Saracenic blood that flowed in upon them, and their only legitimate descendants left upon the face of the earth found homes in the American colonies. Their blood is one of the principal elements in the foundation of the English race horse, but the “lateral action” in his progeny was esteemed a bar-sinister on the escutcheon of the stallion, and it was sought to be covered up with something more fashionable in name. The old saddle horses of England were not all pacers, although that habit of action was very general among them, and in some families it was more uniform and confirmed than in others, and my authority for this conclusion will be found in the detailed account of the horses brought from England to the American colonies early in the seventeenth century. It is evident that from the day the blood of the Saracenic horse was brought in contact with that of the indigenous saddle horse, they were antagonistic, if in nothing more, certainly in the habit of action. The one never moved in the lateral action and the other very generally adopted that form of progression because it was his inheritance. What might have been the result if left to the laws of “natural selection,” it would be impossible to decide; but with the dictates of profit to the master, the mandates of fashion, and above all the accepted teachings of the Duke of Newcastle, the little pacer had no “friends at court,” and all he could do was to get out of the way, with his lateral action. In our own country and under the observation of everybody the pacer shows great tenacity to his long-inherited habit of action, and although buried in non-pacing blood, as supposed, for two or three generations, the pace is liable to appear again, at any time. So it was, doubtless in English experiences, but as the revolution was not retarded by the development of pacing speed, in one hundred years from the restoration, in 1660, there was no longer a pacer on British soil.
