Prince of Thule represents the one considerable element in the Londonderry Stud which was unconnected with Jack, and tended perhaps to counteract his influence. He is described by those who knew him as a pony of exquisite quality, with a small thoroughbred head, prominent wide-set reddish hazel eyes, and an exceedingly fine muzzle. He was short-backed, with strong quarters, somewhat inclined to droop, but finished with a well-carried tail; and he was somewhat cow-hocked. He had big wide feet; and his bone was strong, with large joints. His rein was long and his withers high, though his shoulders were somewhat straight; he was a conspicuously close mover. In colour he was a seal brown, with very bright tan muzzle and flanks; and his mane hung to his knees and his forelock below his nose. Another sire which had a much less important place in the stud was Lion, a dun pony 36 inches high, bred by Mr Bruce of Sumburgh. He is described as a well-coupled pony, but rather long and low. It will be recognised that Prince of Thule is the source, and probably the only immediate source among the Londonderry sires, of whatever may be found in the modern pony to represent that “oriental” type which it has already been said has all along been an integral element in the Island pony. The Jack blood is mainly, if not indeed exclusively, that of the Scandinavian type as opposed to the other type, which is depicted on the Bressay stone, and which is represented in modern times by Multum in Parvo and Boadicea. In Prince of Thule, and whatever impression he may have made on the pony of to-day, is to be found the main source, within the Londonderry strain, to which those must turn who desire to produce the riding as distinct from the draught or pit-pony. It has already been said that his influence is largely counteracted by the extent to which he and his son Oman were mated with mares by Jack and his sons. But his stock remain the best hope of breeding ponies which should combine the many excellences of the typical “Londonderry” pony with the quality and activity in which it is apt to be somewhat lacking. It is worthy of note that the combination of Prince of Thule and Odin blood has always produced a large proportion of good foals. When we come to examine the female lines in the Londonderry Stud, we find, as has already been noted, that they are largely the produce of the sires which we have just reviewed; and we find also that a great proportion of the best animals produced trace from a few of the original mares. No complete analysis in this respect can be attempted; but it will be found that four mares bulk largely in the formation of the stud.
