KING'S PLATE.—Those called KING'S PLATES, are a free gift from his Majesty of 100 guineas each; and it is believed were originally granted as a means of exciting such a degree of emulation, as would probably tend to national advantage, by improving the breed of horses in general; as well as to afford an annual pecuniary advantage (by an additional influx of company) to such CITIES and TOWNS as enjoy the royal favour. NEWMARKET, as the superior spot of sporting celebrity, is particularly honoured, having two in the first SPRING, and one in the first OCTOBER meetings. KING'S PLATES are also given at Newcastle-upon-Tyne, Guildford, Winchester, Ipswich, Burford, Chelmsford, Nottingham, Lewes, Edinburgh, York, Canterbury, Warwick, Lichfield, Richmond, (Yorkshire,) Lincoln, Salisbury, Ayr, Carlisle, and Ascot Heath; the whole of which, except the last, are run for by horses or mares of different ages, carrying such weights as shall be appointed by the MASTER of the HORSE, or whoever he may delegate for that purpose. The KING'S PLATE of 100 guineas, given at ASCOT, and always run for on the first day, (invariably Whit-Tuesday fortnight,) is only for horses which have regularly hunted with his Majesty's STAG HOUNDS the preceding season, and must have been well up with the hounds, at their running up to, taking, or killing, TEN DEER, as an indispensible qualification, without having which they cannot be permitted to start. At the conclusion of the chase, when the deer is secured, those who intend to qualify for the plate apply to the HUNTSMAN, and a ticket is delivered to the rider, bearing the arms of the Master of the Stag Hounds, and the seal of the royal hunt; when which ten tickets are obtained, the horse has secured his qualification, may then be withdrawn from the field, and is not obliged to appear again till the DAY of ENTRANCE at Sunning-Hill Wells, where and when the tickets must be produced, in confirmation of his being duly qualified to START. For the accommodation of the sporting world at large, horses of all ages are permitted to run, carrying the following weights; four years old, 11st. 2lb. five years old, 11st. 9lb. six years old, 11st. 12lb. and aged, 12st. Mares allowed 4lb. The best of three four-mile heats. The following Rules are, by his MAJESTY'S COMMAND, to be strictly observed by the OWNERS and RIDERS of all such HORSES, MARES, or GELDINGS, as shall run for his Majesty's Plates at Newmarket.

Every person that putteth in a horse, mare, or gelding, for the said plate, is to shew such horse, mare, or gelding, with the marks, name, and name of the OWNER, to be entered at the King's stables in Newmarket the day before they run, and shall then produce a certificate under the hand of the breeder, specifying his exact age the grass before.
