350 Forestry Quarterly. 



In the distribution, the biological branches receive 595 hours or 

 40%, the mathematical and business branches 790 hours or 52%, 

 and the economic branches 115 hours or 8%. 



Alathematically, taking field and laboratory work at an 

 equivalent of 2^ hours for one lecture hour, this total represents 

 951 units, distributed through two years, or 15 hours per week 

 for a 32 week session. 



To overcome in part the inadequacy of a time standard the 

 committee has outlined in more or less detail the contents of the 

 various courses as understood by the committee. 



Dendrology. 



There is still considerable difference as to the conception of 

 the scope of Dendrology, and in the methods of teaching it in our 

 forest schools. In some schools, the course in Dendrology is 

 devoted almost exclusively to teaching systematic forest botany, 

 with particular emphasis on the external morphological charac- 

 teristics distinguishing the dift'erent species of trees. On the 

 other hand, some consider that Dendrology properly covers all 

 distinctive characteristics of trees, including those of external 

 form and development, as well as those of internal structure, and 

 those of general and local occurrence or distribution and, indeed 

 all biological facts of the species. In some schools, therefore, the 

 course in Dendrology includes not only the botanical characteris- 

 tics but also the geographic distribution and the various silvical 

 characteristics of the different species. 



It is somewhat of an academic question as to whether the 

 descriptive and the biological or silvical characteristics of species 

 are to be given in one and the same course under the name of 

 Dendrology or be given in different courses. The essential 

 problem is adequately to cover the ground in the schools and to 

 properly co-ordinate the two subjects. In general, it is our 

 belief that when the subjects of Dendrology and Silvics are 

 carried along in the same semester the silvical characteristics of 

 the individual species may best be taught under Dendrology, 

 together with the botanical characteristics. In order to avoid 

 any confusion, however, in this report, Dendrology will be con- 

 sidered to cover only the descriptive part, by which is meant the 

 classification of different species and study of their external
