In all overnight steeplechases and hurdle races, except handicaps, jockeys or amateur riders who have never ridden a winner are allowed 10 pounds; non-winners of five races allowed seven pounds, of ten races allowed five pounds, if such allowance be claimed at the hour of closing of entries. In stakes (handicaps excepted) closing more than three days prior to the day they are to be run, these allowances may be claimed up to 24 hours before the race. These allowances cannot be waived except by permission of the stewards and only for a reason in keeping with the best interests of racing.
