A Harvard man has again won first prize in the annual problem competition of the Boston Society of Architects, according to the announcement of the jury on selecting the winners. The plans of a winter garden in a hotel submitted by Frederick Norman Clark 1G, of Los Angeles, Calif., received the unanimous approval of the jury of Harvard professors, Technology professors, and Boston architects for selection from a field of 90 other projects. The judgement was made early yesterday morning after six hours deliberation, and the award of $150 will be made at the annual dinner of the Society next month.

Following a dinner at the Faculty Club at which members of the jury gave small talks on the history of the prize and the method of judging its winners, the judging body inspected the display of plans hung on the first floor of Robinson Hall Annex. Competitors for the prize, architectural students at Harvard, the Massachusetts Institute of Technology, and the School of the Boston Society of Architects, receive academic credit for their plans. Only one cash prize is awarded, while honorable mention winners receive medals. About 35 members of the University submitted plans, 30 from Technology, and 20 from the Boston school.

Clark is the seventh Harvard man to win the competition in the last eight years, a Technology student having been awarded the prize last year. Theodore Jan Prichard 1G of Thief River Falls, Minn., was the recipient of the first medal, while H. A. Lawrence of M. I. T. was awarded the second. Clark's drawing was characterized by a portico of brilliant red columns, lending a warm atmosphere to the combined swimming pool, tea-room, and dance floor.

The jury is composed of the Education Committee of the Society. On it Harvard was represented by J. J. Haffner, Nelson Robinson Professor of Architecture and Architect to the French Government.
