industrial standardization, lias offered Secre- 

 tary Hoover the use of its machinery in carry- 

 ing out the detailed work on technical projects 

 initiated in the simplification program of the 

 Department of Commerce. The committee 

 hopes to be of great value to Mr. Hoover in 

 this simplification program of the department. 

 It was as a result of this hope that the desig- 

 nation of Mr. Stevenson as a representative 

 came about. 



The American Engineering Standards Com- 

 mittee has been actively at work somewhat over 

 two j'ears, during which time it has brought 

 about a large measure of industry-wide co- 

 operation. In this work more than a hundred 

 national organizations are participating 

 through representatives officially designated by 

 them. The formulation of the standard for 

 each specific project is in the hands of a work- 

 ing committee made up of representatives ofB.- 

 eially designated by the various bodies con- 

 cerned. Eighteen standards have received 

 formal approval as nationally recognized 

 standards, and work on more than sixty other 

 projects is in various stages of development. 

 The committee is maintained jointly by twenty- 

 nine national organizations, including five de- 

 partments of the federal government, nine 

 national engineering societies, and fifteen 

 national industrial associations. 



There are now similar national industrial 

 standardizing bodies in thirteen foreign eoun^ 

 tries, all but one of which were formed during 

 or since the war. Of these the British and the 

 German work is the most extensive, but active 

 and important work is going forward in other 

 countries. 



COMPETITIVE EXHIBITION OF PHOTO- 

 GRAPHS OF MAMMALS AT THE AMERI- 

 CAN MUSEUM OF NATURAL 

 HISTORY 



The American Museum of Natural History 

 plans to hold a competitive exhibition of photo- 

 graphs of mammals at the time of the annual 

 meeting of the American Society of Mam- 

 malogists. These jihotographs will be exhibited 

 in the halls of the museum and all entries must 

 be made on or before May 10. These photo- 

 graphs will be on exhibition to the general 



public for one month. Prizes will be offered 

 for the best photographs, and the conditions of 

 entry are as set forth below : 



1. Only such photographs will be accepted 

 for exhibition as are deemed suitable by the 

 committee. 



2. Photographs will be exhibited and judged 

 under two categories : first, photographs of 

 mammals in the wild state ; second, photographs 

 of mammals in captivity. Photographs of do- 

 mestic mammas are not desired. 



3. The American Society of Mammalogists 

 will be asked to select the judges who will 

 award the prizes. 



4. Photographs may be of any size, but they 

 should be affixed to cardboard or paper mat, 

 preferably gray. No photograph should be 

 sent unmounted. Contestants may submit any 

 number of photographs. 



5. The installation of the exhibition will be 

 done by the museum, and all entries will be re- 

 turned, postpaid, if desired by the exhibitor. 

 The museum, however, would be pleased to ac- 

 cept for its files any photographs of especial 

 interest. While the museum will exercise every 

 possible care of the material exhibited, it does 

 not assume any responsibility for loss or 

 damage. 



6. Cash prizes will be awarded as follows : 

 for the best photographs of mammals in the 

 wild state: Eirst prize, $100; second prize, 

 $60; third prize, $40; for the best photographs 

 of mammals in capitivity: First prize, $50; 

 second prize, $30; third prize, $20. A certifi- 

 cate of honorable mention will be awarded to 

 not more than five additional exhibitors in each 

 category.
