Kon-Tiki in reverse in a slightly safer vessel is the plan of a noted South Sea sailor physician who this week sets out on a 9,000 mile voyage from Wellington, New Zealand to Cambridge where he intends to study at the School of Public Health.

Chief medical officer of the Cook Islands which stretch 1,000 miles across the Pacific from Tahiti to New Zealand, Dr. Thomas R. A. Davis will make the voyage in a 40 foot ketch accompanied by his wife two young sons, and a crew member.

When he reaches Cambridge he plans to live aboard his ship "Miru" named after a Polynesian goddess anchored in the Charles. When at work in New Zealand, Davis depends upon the ship to reach the more than 16,000 people in the Islands.

The son of a South Sea trading Vessel captain and a Polynesian princess, Davis hopes to reach Peru in 50 days, but he cannot tell how long it will take to reach Cambridge.
