THE POPULAR SCIENCE MONTHLY 



Dr. O. T. Hood, 

 Vice-president for the Section of Mechanical Science and Engineering, U. S. Bureau 



of Mines. 



of the U. S. Public Health Service, on 

 "The Health of the Mother in the 

 South, ' ' and one by Professor Chas. 

 E. Munroe, of the George "Washington 

 University on ' ' The Explosive Re- 

 sources of the Confederacy during the 

 War and Now: A Chapter in Chemical 

 History," each admirably adapted in 

 subject matter and treatment to the 

 occasion. The sections of the associa- 

 tion do not have programs of technical 

 papers when the ground is covered by a 

 society meeting in affiliation with it. 

 In that case programs of general inter- 

 est are arranged by each section. The 

 American Association is thus in respect 

 to the research work of the special 



sciences essentially an affiliation of so- 

 cieties rather than of individuals, but 

 it retains the important functions of 

 keeping the sciences in touch with each 

 other and representing science before 

 the general public. 



The Monthly is conservative in 

 printing portraits of living men of 

 science, but it aims to reproduce once 

 a year the photographs of the presi- 

 dent and vice-presidents of the associa- 

 tion, as it seems desirable for as large 

 a number as may be to become ac- 

 quainted to this slight extent with those 

 most actively engaged in advancing 

 science in America. The officers elected 

 at Atlanta continue the high traditions
