The first snowfall in Cambridge may mean that to the ordinary hazards attendant upon crossing Harvard Square is added the possibility of drowning, but those brave enough to venture out before its remains disappear have several interesting lectures to attract them today. Chief among them will be the one by Professor Murdock on "James Fennimore Cooper". Cooper is an author whose popularity is not today all that it has been, but he still has a following among those who appreciate adventure stories. The lecture will be at 10 o'clock in Harvard 2.
