Leaving Washington immediately upon his resignation as financial and executive adviser to the Secretary of the Treasury, O. M. W. Sprague, Edmund Cogswell Converse Professor of Banking and Finance, arrived in Boston late last evening, it was revealed early today, and is understood to have gone direct to the Business School, spending the night at the home of Wallace B. Donham '99, Dean of the School. He left New York early in the afternoon, it is believed, coming up on the train with Walter Lippmann '10, who spoke to a small gathering at Kirkland House last night. Lippmann, who spent the early part of the evening with Edward a. Whitney '17, Master of Kirkland House, would make no statement in connection with Sprague's return to Boston.
