A dispatch from New Haven to the Boston Herald, dated last evening, says : "A letter was received tonight by the secretary of the Yale Boat Club, from the secretary of the Harvard Boat Club, in which it was stated that Harvard did not understand that the graduate committee had full power in the premises, and asking that they be advised on that point. If the committee had full power in the matter, they could not imagine that a joint committee should be unable to reach a satisfactory conclusion, and they proposed to abide by their decision. But they wished to express the opinion that, if the joint committee were unable to make satisfactory arrangements without outside assistance, the race should be abandoned. The Yale men were of the opinion that the joint committee would be able to satisfactorily settle all ordinary questions, but recognize the fact that there might be some points to decide in reference to which the separate committees would have decidedly partisan views, and have considered that the only way in which these questions could be decided is by the action of a disinterested neutral committee. In the letter of the 22d inst., they agreed to leave these questions to this committee and to act by its decision."
