RULES.The rules which will govern the races are the same as those of the four past years.

The crews will be ready at the Brookline Bridge promptly at the appointed hour, 4.30 p. m. The stern of each shell will be held from a boat attached to a rope stretched across the river. As soon as the shells are in position, one long whistle will be blown as a preparatory signal. Twenty seconds after this signal, three short, sharp whistles will signify "Are you ready?"

The word "go" will be given at any moment after the three whistles.

To recall the shells, if necessary, the referee's tug will stop and a gun will be fired, but there can be no signal after ten strokes have been rowed.

The finish line is the imaginary prolongation of the face of the brick wall on the west of Otter Street, Boston.

Shells will cross this line between Beacon Street, and the judges boat, which will bear a flag.

Except as above, the races will be governed throughout by the Laws of Boat Racing as adopted by the National Association of Amateur Oarsmen. Should the weather necessitate postponement, notice will be sent to the college boat house as early as possible.
