Film on Heat Control Will Feature Engineers' Meeting

The Harvard Engineering Society will present a sound motion picture entitled "Heat and Its Control" tomorrow evening at 7:30 o'clock in Pierce 110.

This film, put out by the Johns Manville Company, shows the insulation of houses and the uses of insulation in solving other problems of heat control. It is reported to be notable for its clear exposition and demonstration of the physical principles involved and should be of popular scientific interest.

Another movie depicting the metallurgy and the manufacture of wrought iron will be shown, followed by an important business meeting.
