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.

 Department to determine the effect of the work on the eyes 



Have You Perchance a "Vocational 

 Disease ? " 



IN an exhaustive study which is being 

 carried on by the United States 

 Public Health Service a great many 

 interesting things are being found out 

 about the effects of v'arious vocations 

 upon government employees. 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.
