Davis's Ketch on Final Boston Lap

NORFOLK, Va., Oct. 29--The Harvard-bound ketch Miru left here late today on the last leg of its 10,000 mile journey from New Zealand to Boston.

Thomas R. Davis, enroute to the School of Public Health, said he plans to sail to Boston via the inland waterway. The 45-foot ketch docked late last night after a stormy trip from Morehead City, N. C.

Davis set sail from New Zealand during the summer. He wanted to test a thesis of his on the trip from New Zealand to Peru--that the currents which took the Polynessians across the Pacific also went the other way, and they could have returned to Peru merely by shifting currents. It took him 68 storm-battered days to reach Peru.

Earlier this month, he was the object of a wide sea-air search when he became ensnarled in the tail-end of a hurricane off Miami. He was later found safe.
