Under the aegis of the Harvard Engineering Society three motion pictures of engineering projects will be presented free to the public tomorrow evening, at 7 and 8.30 o'clock, at the Institute of Geographical Exploration.
Films scheduled to be shown are 'Steel--Man's Servant," "Norris Dam and TVA Work," and "Grand Coulee Dam."
The first, a technicolor sound picture with Edwin C. Hill as commentator, follows the manufacture of steel from the mines to the finished product.
