The Harvard-sponsored Red Cross blood drive is falling short of its goal with three more days remaining in this semester's campaign, Pia Maybury-Lewis, co-chairman of the Harvard blood drive, said yesterday.

As of early yesterday afternoon, the drive had collected 775 pints of blood towards its target of 1400, Lewis said. "I'm an optimist, but now I'm scared that we won't even reach 1200 pints," she added.

Maybury-Lewis said she believed a lack of publicity about the drive caused the shortfall, adding that no notices ran in campus newspapers.

Maybury-Lewis said that fewer people are walking in to donate blood without an appointment than in the past. Donors can go to Memorial Hall today and tomorrow from 2 p.m. to 7:45 p.m., and Friday from 9:45 a.m. to 3:30 p.m.
