HAMBLETONIAN, 10.—It has been a matter of constant regret that in the compilation of the first volume of the Register I attached the name “Rysdyk’s” to this horse, and this misstep has served as a kind of apparent justification for very many men to seize upon the name “Hambletonian,” with their own name as a prefix. This has led to great confusion and annoyance to all that body of men who have anything to do with records and correct pedigrees. Fortunately, however, the evil has become so apparent that many writers are beginning to use the numbers, and we now very frequently hear men speak of “Hambletonian, 10,” as the true designation of this horse. As no horse of any blood or period in this or any other country has excited an interest so universal, or represented such a vast sum of money in his offspring and descendants, I must try to give an account of him and his family—ancestors and descendants—as full and accurate as the materials at hand will enable me. He was a beautiful bay color, bred by Jonas Seely, of Sugar Loaf, Orange County, New York, foaled 1849, got by Abdallah; dam the Kent Mare, by imported Bellfounder; grandam One Eye, by Hambletonian, son of Messenger; great-grandam Silvertail, by imported Messenger; great-great-grandam Black Jin, breeding unknown. He was sold with his dam, when a suckling, to Mr. William M. Rysdyk, of Chester, in the same county, and he remained his till he died in March, 1876. He has been described by a great many writers, but the most minute and accurate description I have ever seen is from the pen of “Hark Comstock” (Peter C. Kellogg), which I will here present, and after it note any point upon which my own judgment differs from his. It should be remembered that this description was made when the horse was breaking down with the weight of years:
