ROCKINGHAM.—This horse, now in so much estimation as a STALLION, proved himself, by his performances, to be one of the best bred and best bottomed of any this kingdom ever produced. He was bred in the north, by MR. PRATT, foaled in 1781; and got by _Highflyer_, out of _Purity_, who was got by _Matchem_, out of MR. PRATT'S old _Squirt_ mare. In 1784, when three years old, he won a sweepstakes at Nottingham of 50 guineas each, 3 subscribers. In 1785, when MR. WENTWORTH'S, he won a match for 500 guineas over the Beacon Course at Newmarket. The same meeting he won the Jockey Club Plate, beating _five_ others: he also beat his Royal Highness the Prince of Wales's _Hardwicke_, 9 stone each, over the Beacon, 300 guineas. He was then purchased by the PRINCE, and beat _Clay-hall Marsk_, a match, Beacon Course, for 500 guineas, giving him 5 lb. in weight. In 1786, he won a 50_l._ Plate at Newmarket, beating _Delpini_, _Clay-hall_, and _George_. He won the subscription of 50 guineas each, (6 subscribers,) at Ascot Heath, and a 50_l._ Plate. At the sale of his Royal Highness's stud he was bought by MR. BULLOCK. He then won the KING'S HUNDRED at Litchfield; 70 guineas at Newmarket, and 60 guineas also; beating four others; as well as 70 guineas, beating the well known _Drone_, and several others. In 1787, he won 525 guineas, (the great subscription of 50 guineas each, _half forfeit_,) beating _Fox_, _Delpini_, _Marplot_, _Drone_, _Oberon_, and _Pilot_; receiving forfeit from MR. O'KELLY'S _Dungannon_, and six others. He also won a 50_l._ the KING'S two PLATES; the renewed 140 guineas, 70 guineas, 60 guineas, and 70 guineas, all at Newmarket; the King's Plate at Guildford, the King's Plate at Winchester, the King's Plate at Nottingham, the King's Plate and the Town Plate at York.
