COLUMBIA has sent us another challenge for an eight-oared race. The time and place are left to our decision, as before. Last year our crew were able to do better in their race with Yale from having previously rowed with Columbia. Moreover, to pull in a single race is a small object for men to look forward to during a year's hard training; and so the more races a crew can row, the more pleasure there is for them individually. Here, then, are the two things which make a race with Columbia desirable, - improvement of our chances with Yale and more fun for the crew. Harvard withdrew from the Association, and entered a series of races with Yale; since then she has given Cornell an opportunity to challenge her, which Cornell failed to improve, and she has accepted a challenge from Columbia. More than this can hardly be expected of her; and now she ought not to so place herself that hereafter any undesirable race can be forced upon her. She ought not to involve herself in a series of races from which she cannot withdraw at once; and if the challenges from Columbia are accepted, it ought to be understood that, in accepting these challenges, Harvard does not in the least bind herself to accept others.
