Lagging behind its expected totals, the P.B.H. blood drive has netted only 865 pints in the first three days of its seven day campaign, Laurence I. Alpert '54 and Gordon L. Brumm '53, co-chairmen of the drive, announced last night. At this same time last year 1,234 pints had been collected. Brumm hastened to add, however, that he expects donations to increase later this week. He predicted that the campaign will have collected between 2,200 and 2,300 pints when it ends next Tuesday.

Yesterday was the best day so far, betting 341 pints. Four Radcliffe girls have been calling students who have not met appointments.

Results Go to 400 School

Alpert disclosed that reports of the drive will go to 400 colleges throughout the country in an effort to stimulate similar drives elsewhere. Alpert and Brumm have joined with Phillip D. Levin '53 and Thomas H. Petschek '53, who led drive in 1951, to form a permanent committee for this.

Colleges which are interested will be sent a complete outline of the program here as a guide sheet for their campaigns.

Alpert stated that Harvard, as an average-sized college, has a potential of 4,000 pints. He pointed out that a large percentage of the Red Cross's demand would be met if even 20 colleges of similar size undertook a comparable campaign.

The Harvard blood-letting program has long been recognized as one of the nation's most successful.
