The extraordinary memorial to the Columbia Boat Club which appeared yesterday morning, signed by certain Harvard alumni, is to us inexplicable and astounding. The only conjecture that can be made to explain its appearance and its import is that its framers and signers are ignorant of or have utterly ignored the statements recently advanced by the Harvard Boat Club, in explanation of the conduct of the crew. The students of Harvard have read the statements of Columbia and of their own crew; from these they are satisfied that without question the Harvard crew can not be justly accused of dishonorable conduct; that a misunderstanding existed, and for this misunderstanding they were not to blame. Certain graduates of Harvard without, as we are convinced, due consideration of both sides of the question, choose to impute to the Harvard crew dishonorable motives and actions. This proceeding is, in our opinion, thoroughly unjust, inconsiderate and ill-advised. Furthermore, it is an insult and affront to the students of Harvard who, relying upon the words and statements of their crew, as gentlemen of honor, are thus publicly rebuked. Columbia, it is possible, will place more reliance upon the word of honor of the Harvard crew than have certain graduates of Harvard itself. If not, it is certainly best that for the future all races between Harvard and Columbia be given up.
