The Class of '46, first to enter Harvard during wartime since 1917, will find the halls of Harvard crowded with men in uniform, all receiving intensified training in technical and administrative subjects essential for the prosecution of a "war of science."

At the Business School 150 Army Air Corps officers, the first such group in the nation's history, will be trained in administrative statistics, equipping them to become human encyclopedias on air force information wherever they may be stationed. A graduate will serve as the right hand man of the Air Force commander in the area, dispensing information about location of airdromes, fuel supply, numbers of planes, and other vital information.

Navy Supply School Here

Twenty-four officers from the government school in Philadelphia, closed for the duration, are supplying the instruction for a large group of junior officers in the Naval Supply Corps, also based at the Business School. During a 12 weeks course given last summer, 392 men, including John Roosevelt, the President's son, were trained in the problems and methods of supply. Upon graduation a part were assigned to service at sea, the remainder being given posts at shore bases. A longer course was given during the past winter from September to March. At that time another 250 men were graduated to join the first group, a majority of which by this time had seen service in the Pacific battle areas.

Displacement of the Freshmen in the Yard is the result of its occupation by the Navy, which intends to stay for the duration. 500 Radio Communication officers will begin to move in about June 15 to establish one of three radio training centers in the country. Even President Conant's house has been pressed into service by the armed forces and will serve as the headquarters of the new Naval unit, as well as the undergraduate ROTC program.

Officers Barracked in Yard

The radio school is intended to have a potential capacity of 1000 officers in staggered six-month courses with 125 men in each section. They will be barracked in Freshman halls beginning in the sector of Hollis, Stoughton, Holworthy, and Thayer and expanding southward.

One hundred men are participating in the two year course for the ROTC Quartermaster Corps, like the Air Force program the first of its kind in the nation's history.
