Blue books for the race for organized fours have been left at Leavitt & Peirce's and the boat house. Men who have rowed on 'varsity or class crews are barred out, but if two or more crews of such men enter there will be a senior race for which prizes will also be given. The course is about three quarters of a mile from the Harvard Bridge to the Union. The race will if possible be rowed in one heat. Flags have been offered for the winners by Messrs. Weld and Forbes, and if five or more crews enter, the second crew will also receive prizes. Crews are urged to sign early. The fee is 50 cents per man.
