 The Weatherby family succeeded Cheney as the keepers of the most complete set of racing records, and in a later work which came into their possession, published in York in 1748, the result is recorded of a race run in September 1709 on Clifton and Rawcliffe Ings, near York, for a gold cup of £50.In 1740, Parliament introduced an act "to restrain and to prevent the excessive increase in horse racing"; this was largely ignored and in the 1750 the Jockey Club was formed to create and apply the Rules of Racing.However, until the 1760s, individual horses seldom ran more than five or six times, due to the scarcity of prizes on offer, but this began to change with major race meetings expanding the prizes on offer.
