ANEW submachine gun which shoots .45 caliber automatic , pistol bullets at the rate of 500 a minute is now being- turned out by the Harrington and Richardson Arms Company, of Worcester, Mass., at the rate of 1,000 guns a day.

HUMAN reactions to colors are being studied at various universities and other institutions. When the scientists have the data on which to base opinions, their findings will be influential in lighting and decorating schemes. Certain basic facts have emerged already.

First of his color cartoons reached the screen recently as a nine-minute show. Instead of drawings, Pal uses wooden characters which perform on tiny sets, with synchronized music, songs, and special effects.
