Each competitor (including the coxswain) in eight- and four-oared races shall attend to be weighed (in rowing costume) at the time and place appointed by the committee; and his weight then registered by the secretary shall be considered his racing weight during the regatta. Any member of a crew omitting to register his weight shall be disqualified. _Flag._--25. Every boat shall, at starting, carry a flag showing its colour at the bow. Boats not conforming to this rule are liable to be disqualified at the discretion of the umpire. _Umpire._--26. The committee shall appoint one or more umpires to act under the Laws of Boat-racing. _Judge._--27. The committee shall appoint one or more judges, whose decision as to the order in which the boats pass the post shall be final. _Prizes._--28. The prizes shall be delivered at the conclusion of the regatta to their respective winners, who on receipt of a challenge prize shall subscribe a document of the following effect:-- 'We, A, B, C, D, &c., the captain and crew of the ______________ and members of the ____________________ Club, having been this day declared to be the winners of the Henley Royal Regatta ____________________ Challenge Cup, and the same having been delivered to us by E F, G H, I K, &c., Stewards of the Regatta, do hereby, individually and collectively, engage to return the same to the Stewards on or before June 1, in accordance with the conditions of the annexed rules, to which also we have subscribed our respective names.' _Committee._--29. All questions of eligibility, qualification, interpretation of the rules, or other matters not specially provided for, shall be referred to the committee, whose decision shall be final. 30. The Laws of Boat-racing to be observed at the regatta are as follows (_see chapter on this subject_). A good deal of the history of old regattas at which watermen contended is necessarily mixed with the history of the rise of professional racing, and will be found to be dealt with under that heading in another chapter.

The first principles of oarsmanship may be explained to a beginner in a few minutes, and he might roughly put them into force, in a casual and faulty manner, on the first day of his education. In all pastimes and professions there is, as even a child knows, a very wide difference between the knowing how a thing is done and the rendering of the operation in the most approved and scientific manner.
