��Shipping Sugar- Coated Education by the Trunkful

BORROWING thf idta of the travel- ing libraries, the Bureau of Visual Instruction, of the University of Cali- fornia, has perfected a plan for sending out trunkfuls of information and educa- tional exhibits on interesting subjects. The exhibits illustrate processes by which raw wheat or oats are made into cereals, hides finished into shoes, lead and oil made into paint, snow converted into electric power, crude oil into fuel and lubricants, rub- ber into tires, graphite into pencils, hemp and flax into rope, etc.

The object is to inten- sify interest in places and products and in indus- trial and social develop- ment, but to do it in such an interesting way that the educative ele- ment will be completely wrapped up in the en- tertainment, asthemedi- cated pill is seemingly lost in its sugar coating.

��The particular exhibit illustrated here concerns the manufacture of paint. Slides containing the printed informa- tion covering all questions that might arise on the subject, are drawn out at the sides of the cabinet, while in the cabinet itself are slabs showing different tints and viols containing the different pigments and ingredients used. The stand is collapsible.

For exam- ple, all of the workers in the Treasury are having their eyes examined to determine the effect of confinement upon the men and women engaged in niakingourmoncy for us. These tests are being conducted by Assistimt Surgeon-C.eneral Kerr.

In the accompanying photogra|)h, Dr. George H. Collins, of the Public Health Service, is preparing to examine the eyes of a treasury employee. After he has made the test he will prescribe for her eyes, if necessary-. An interesting sidelight of the investigation will show whether or not the lighting system of the Treasury Building is good. Steps are already being taken to correct many of the lighting faults that have existed.
