The University crew leaves to-day for New London. Its Columbia rivals are already on the Thames hard at work. That our crew will hold their position on the river of last year is ardently hoped for, and reasonably to be expected. The exhibition row of the crew yesterday was extremely gratifying to the large audience which thronged the boat-house to witness it. The crew showed great improvement in the style and finish of its stroke; if it has the same lasting power that it possessed a year ago, it should win both its races. Captain Mumford is to be congratulated upon the excellent work which the crew has done under his captaincy. The crew has worked as hard as all Harvard crews are expected to do, and their labor, we believe, will not be in vain. The college appreciated the exhibition row which was given yesterday quite as much as any favor which has ever been conferred upon her by a university captain; and the enthusiasm of the spectators dispelled all fears that the college had no interest in the crew. Well, the crew has gone, and there will be a brief week of anxious waiting. Let us hope we shall have two more victories to record, and two more pennants to adorn the walls of the trophy room. The victories must and will come; but if they do not, it will be because the better crew is Yale's or Columbia's; not because Harvard's crew has proved unworthy of herself and the college.
