170 Forestry Quarterly 



The forest academies of Eberswalde, Miinden, and Tharandt 

 are closed during the war, but the Universities of Munich, 

 Giessen and Tubingen keep open and register students even if 

 absent. 



Even the Catalpa has an enemy that can become serious, namely 

 the Catalpa sphinx, a large yellow and black caterpillar with a 

 stout black horn. It is described in Farmer's Bulletin 705, U. S. 

 Department of Agriculture. Hand picking and spraying with a 

 combination of arsenicals and Bordeaux mixture is recommended. 

 A wasp-like fly, in evidence in September and October, is a para- 

 site, during the presence of which the caterpillars should not be 

 killed, but rather collected in a barrel covered with wire netting, 

 in which they may hatch the parasite. 



Two useful compilations have been made, which give an 

 insight into the status of the academic side of forestry in the 

 United States and Canada, namely a census of students and 

 alumni and their employment made by the Yale Forest School 

 News and a canvass of the forest schools as to number and 

 character of students as well as of instruction, number of in- 

 structors and their salaries and load of work, by Professor H. 

 Winkenwerder of the College of Forestry in the University of 

 Washington. The information collected by the Yale Forest 

 School News is in print (in Volume IV, Number 1, January, 

 1916) and may be quoted: 



There were 634 bachelors and 523 masters of forestry (or 

 equivalent titles) graduated from the 22 schools reported, but of 

 these 1157 technically educated men, only 803 are employed in 

 forestry work. Details of the manner in which the schools are 

 run are given for each school, which are highly interesting. 



The information gathered by Prof. Winkenwerder is more 

 complicated and is so far only private. We hope to have an 

 analytical discussion of it by the collector in a future issue. 

 Here we may, however, state that in the 19 institutions for which 

 data are given, there seem to be around 900 students enrolled for 

 straight forestry work, besides some 500 taking secondary work 

 in forestry. 



There were 72 instructors in these 19 institutions, 61 giving 

 full time, ranging from one to eleven JBstructors in one school,
