The officers for the class races are as follows: referee, J. J. Eustis; judges of the finish, Joseph Lee, E. T. Cabot; starter, W. G. Borland; time keepers, G. R. Agassiz, D. C. Clark. The referee's tug will start at West Boston Bridge, Charles Street, at 12 45 punctually. Tugs following the race are requested to keep behind the referee's boat.

RULES UNDER WHICH THE CLASS RACES WILL BE ROWED.The race will be started at 1.45 promptly. Each crew is requested to be at the Brookline Bridge at 1.30 o'clock, when the railroad draw will be opened. Any crew, not on hand at this time, will run the risk of being left out of the race.

As soon as all the crews have passed through the draw, a long whistle will be sounded from the Referee's tug as the signal for the crews to get into line. A rope will be stretched across the river, to which four tow boats will be moored, at distances of one hundred feet apart. A man in each boat will hold the stern of a shell. As soon as the shells are in line, two whistles will be sounded as a signal for the men to come out to the full reach.

The boats will then be started in the following manner:

The Referee will say, "Gentlemen, are you ready?" and getting no reply, and seeing no coxswain hold up his hand as a signal that his crew is not ready, the Referee will fire a shot gun, after an interval of from two to four seconds as a signal to "GO."

The signal for a recall will be a succession of short whistles, but there will be no recall after the first ten strokes have been rowed.

No crew shall take another crew's water, except at its own peril of being ruled out in case of a foul.

By order of Executive Committee,

May 6, 1886.
