It has been brought to our attention that you have r 'ecently received, a letter addressed to "Dear George" from "Elliot." The writer, it appears, was Mr. Elliot Richardson, chairman of 'Citizens for Ocean Law and former Ambassador to the Unit e d Nations Law of the S6a.-Conference, who was asking you to reconsider U.S. refusal-to@join the Law of the Sea process. Though'we cannot address you by your first name, we feel compelled to state our conviction that it would be neitheriin your interest no r in that of our nation to follow Mr. Richardson's advice. President Reagan has made clear that sound reasons prevent this nation from endorsing the Law of the Sea Treaty.
