The Clerk of Scales is the official (under the Racing Secretary's Office) who "runs" the Jockeys Room, weighing the jockeys out before a race and reporting any discrepancies in their weight to the stewards. His job is to make certain the jockeys are at or under the legal weight for that race's (and their mount's) allowance. The Clerk of Scales also notes and reports any changes of jockeys or of silks, and provides the Paymaster of Purses with a list of riding fees due each jockey that day. This is also the official who can be seen in the Winner's Circle after the race, recording the weight of every rider (and his gear) after he or she dismounts, to make certain no "weight was dropped" after the jockey's pre-race weigh-in.
