MAMBRINO.—This great son of Messenger was a bright bay with a star and one white ankle. He was fully sixteen hands high, with great length of body and generally of coarse appearance. He was foaled 1806, and was bred by Mr. Lewis Morris, of Westchester County, New York. His dam was by imported Sour Grout, out of a mare by imported Whirligig, and she out of the famous Miss Slammerkin, that is a well-known landmark reaching beyond the Revolution. The late William T. Porter, of the _Spirit of the Times_, stoutly maintained that Mambrino was not a thoroughbred horse, and his reasons seemed to rest wholly upon his coarse and cart-horse appearance. Technically, Mr. Porter was right, but the trouble did not rest with the dam, as he seems to have supposed, for I have seen the original certificate of breeding in the handwriting of Mr. Morris, his breeder, and there is no slip on that side of the pedigree. Mr. Morris was a prominent breeder and racing man for many years and his character was without taint. The pedigree is a very long one and I would be very far from vouching for the truth of the remote extensions, but back to the mare by Cub, imported by Mr. De Lancey, who bred Miss Slammerkin, there can be no mistake. In the spring of 1810, then four years old, he was purchased of his breeder by Major William Jones, of Queens County, Long Island, and in the autumn of that year he was trained and ran for the two-mile purse at the old Newmarket Course, Long Island, and it is said gave some evidence that he could run, but after that he was never trained nor started in a race, from which we may conclude he was not a race horse, or his owner, who bred and ran his horses, would have given him another trial. In 1811 he was put in the stud and made the season at Huntington, Long Island, in charge of Ebenezer Gould. It is not known where he made the season of 1812, but probably in Orange or Dutchess County. The years 1813-14-15 he was in charge of my late highly esteemed and venerable correspondent, David W. Jones, on the borders of Queens and Suffolk counties, Long Island, where he covered about two hundred and fifty mares. In 1816 he was in one of the river counties, in 1817 at Fishkill, and 1818 at Townsend Cock’s, Long Island. In later years he changed hands many times, at from two hundred to two hundred and fifty dollars, and there is no published trace of him till we find that he made the seasons of 1825 and 1829 at Pleasant Valley, Dutchess County, and he died the property of Benjamin Germond, on the farm of Azariah Arnold in Dutchess County, about 1831.
