106 REPORT OF NATIONAL MUSEUM, 1921. 



from selected stock grown by him. This exhibit represents an in- 

 dustry that is gaining in importance in the United States, and is 

 deserving of more recognition. 



The importance of the closer utilization of wood as a conserva- 

 tion measure, and the practicability of laminated wood construction 

 in the manufacture of a number of articles subject to severe usage, 

 is shown by a series of 23 specimens of built-up airplane wing 

 ribs, tenpins, duckpins, and shoe lasts, which were received by trans- 

 fer from the Forest Products Laboratory at Madison, Wis. 



A moth-proof cedar chest was presented by the Piedmont Red 

 Cedar Chest Co., of Statesville, N. C. This chest, designed and 

 built especially for exhibition in the National Museum, is devoid of 

 all brass trimmings, save the keyhole plate, and is finished with a 

 high wax polish, so that nothing has been added to detract from 

 the simple beauty of the wood itself. 



As accessions of imj)ortance other than those mentioned under 

 textiles, medicine, and wood technology, there should be mentioned 

 the transfer from the States Relations Service of the Department 

 of Agriculture, of an exhibit of over 100 examples of canned fruits, 

 vegetables, fish, and meats, which has attracted the attention of large 

 numbers of visitors. This appetizing array of canned foods was 

 put up by children according to the coldpack method, and repre- 

 sents a selection from the jars winning prizes in 17 State contests 

 between members of boys and girls canning clubs. The 10 best 

 jars entered in each State contest were selected by the State club 

 leader, and sent to Washington for exhibition in the National 

 Museum, as an additional honor to the youthful prize winners. These 

 examples of an important work in food conservation, now being 

 carried on by children all over the United States, represent a great 

 advance in camiing methods, and show that home-put-up foodstuff's 

 which can be shipped about from local to State fairs, and across 

 the country to Washington, for exhibition under severe conditions 

 of light and heat, well deserve the attention they have received in the 

 section of foods. 



Fifteen large charts, showing graphically the composition and 

 fuel value of important articles of food, were added to the section of 

 foods, by transfer from the Department of Agriculture. They serve 

 to further explain the models of 100 calorie portions, and the exhibits 

 showing the principal classes of foods, which were mentioned in a 

 previous report. 



The importance of dehydration as a means of conserving a local 

 surplus of fresh foods, and of avoiding many transportation difficul- 

 ties, is brought to mind by a series of 22 specimens of dehj^drated 

 California fruits and vegetables, contributed by the Caladero Prod- 

 ucts Co., Atascadero, Calif.
