What might have been the particular merit of the English horse at the time of the Norman invasion, is not known, but it is certain that the Saxon cavalry under Harold were speedily overpowered by William, at the battle of Hastings, which at once secured the throne to the Conqueror. History first informs us of the improvement of British horses, by importations from abroad during this reign, which consisted of a number of Spanish stallions. These were supposed to be strongly imbued with the Arabian blood, which had been brought over to that country by the Moors, who had founded the Saracenic empire in the Peninsula, three centuries before. More than a century later, John made some importations from Flanders, to give weight and substance to their draught and cavalry horses. The improvement of their various breeds was afterwards pursued, with more or less judgment and zeal, by other British monarchs, till they reached their highest excellence during the middle of the last century. Flying Childers, Eclipse, Highflyer, and others on the course, have probably exceeded in speed anything ever before accomplished; while the draught-horse, the roadster, the hackney, the cavalry-horse, and the hunter, attained a merit at that time which some judicious authorities claim has not been since increased. It is even asserted, that some of the more serviceable breeds have been seriously injured by too great an infusion of the blood; while the almost universal absence of long heats on the turf has tended to the improvement of speed rather than bottom in the race-horse. The improvement of the horse in this country has not been a matter of record or history, till within a comparatively recent period. But it has silently, and with no little rapidity, been going forward for more than a century, till we have obtained a race of animals, throughout the Eastern and Middle states at least, which probably equal those of any other country for adaptedness to draught, the road, and the saddle. This improvement has been mainly brought about by the importation of some of the _best and stoutest of the English blood_. In breeding from these for purposes of utility, particular reference has been paid to strength, enduringness, and speed. No horses surpass our best four-mile bloods; none equal our trotters; and though much inequality exists in those bred for various other uses, yet for profitable service, it is believed, no equal number of animals elsewhere can exceed those in the region above indicated. It would be a superfluous task to attempt enumerating all the imported horses that have contributed to this improvement. Each good animal has done something. But among the earlier horses which may be named with distinction, as having effected much for our useful beasts, are Lath, Wildair, Slender, Sourkrout, Tallyho, Figure, Bay Richmond, Expedition, Baronet, and a host of others.
