THE AMERICAN JOURNAL OF HYGIENE 



This journal published by the Johns Hop- 

 kins Press and supported by the DeLamar 

 Fund of the Johns Hopkins University will 

 be devoted to the publication of papers rep- 

 resenting the results of original investigations 

 in the domain of hygiene, using the term in 

 the broadest sense to cover all applications of 

 the mathematical, physical, ekemical, medical 

 and biological sciences to the problems of per- 

 sonal and public hygiene. At least six num- 

 bers, corresponding to a volume of about 600 

 pages, will be issued annually, beginning with 

 January, 1921. Investigations of unusual 

 length will be published in a series of sup- 

 plementary monographs. 



Dr. William H. Welch is the editor with Dr.

THE YALE FOREST SCHOOL 



On December 21 and 22 the alumni and 

 former students of the Yale Forest School 

 will celebrate the 20th anniversary of its 

 founding. In September, 1900, this school 

 first opened its doors for the training of pro- 

 fessional foresters. The school was founded 

 by Gilford Pinchot, forester in the Depart- 

 ment of Agriculture, to provide trained for- 

 esters for employment in the U. S. Forest 

 Service, with the ultimate purpose of admin- 

 istering these National Forest lands. At that 

 time and for five years thereafter these forests 

 were in the hands of the General Land Office 

 of the Interior Department, but in 1905 they 

 were transferred to the Department of Agri- 

 culture, and the personnel of the Forest Serv- 

 ice, recruited partly from the men trained at 

 Tale, took hold. On Mr. Pinchot's retire- 

 ment in 1910, he was succeeded by Henry S. 

 Graves, under whom the Tale School has been 

 built up. When Mr. Graves resigned in 1919, 

 his successor was W. B. Greeley, one of the 

 earlier graduates of the Tale School. 



Of 513 men who have received professional 

 training at the Tale School, 97 are still em- 

 ployed by the Forest Service. Of these, 12 

 are engaged in research, and 85 in administra- 

 tion. Thirty-eight, nearly half, of these men 

 are now in the office at Washington or in the 

 seven district off.ces into which the National 

 Forest administration is divided, and have 

 direct charge of the general policies of the 

 service in those districts. Twenty-six are 

 supervisors, each in charge of a N'ational 

 Forest whose area averages over a million 

 acres. One of these supervisors, in Alaska, 

 controls twenty million acres. 



There are now twelve forest schools which 

 give more or less adequate professional train- 

 ing in forestry by devoting four to five years 

 of schooling to this subject, and through a 

 faculty sufficiently large to x>ermit of sub- 

 division of teaching and thus provide ade-
