What probably in the beginning most helped to give the Club that power it now exercises was its interest in Newmarket Heath. For two centuries and more Newmarket has been to trainers and jockeys what various seats of some particular industry are to the persons interested in that industry. The Jockey Club, which has no palatial London dwelling-place--having, as a matter of fact, only an office there for the transaction of business--possesses a suite of apartments at Newmarket, and holds in its own right, or by lease--chiefly the latter--all the land of the Heath now being used for the various racecourses or public training-grounds, from which it derives a large income, each horse exercised at Newmarket being charged for at the rate of five guineas per annum. Considerable sums of money are also derived from charges of admission made at various stands and enclosures pertaining to the different racecourses, and these are being multiplied by order of the Club, which seems to be fashioning racing on the Heath pretty much in the same way as if the meetings held under its auspices were gate-money meetings. II. The "Rules of Racing," which have for a long period given law to the turf, and the code of honour pertaining thereto which all racing men respect and obey, have been from time to time revised and made more perfect by the Jockey Club, which numbers at the present time about one hundred members, and makes itself felt through the stewards, to whom, for all practical purposes, its powers are delegated. During their period of office, to which they are nominated by their predecessors, the stewards address those who are interested in the sport of horse-racing through the official "Calendar," which is published in London by the Messrs. Weatherby, of Old Burlington Street, who may be termed the mouthpiece of the Club. In racing circles these gentlemen are much respected, one of them being "keeper of the match-book," and it would be rather difficult to say what functions connected with horse-racing they do not take part in.
