In the Second Year. 



Durint,^ the secnnd year tlie fcrotry 

 student j^ets a still morr inliniale 

 knowled^^e of trees li.ilh a-> indixidual^ 

 and in their economic aspects. He 

 learns how trees come into existence, 

 how they live and work and, not least, 

 how they get along with their neigh- 

 bors. He studies the methods of de- 

 termining the contents of single trees 

 and stands of trees in terms of cords 

 or board feet. He learns how the rules 

 for determining the board feet in a log 

 were made, and is ^hown why some of 

 those in use are so unjust to the seller. 

 He is taught how to make volume 

 tables according to the diameter of the 

 trees or to the diameter height or ac- 

 cording to the diameter and the num- 

 ber of logs in the tree. He is tho- 

 reiughly grounded in the methods of 

 cruising and estimating timber and the 

 application of the various methods to 

 the different parts of the country, ihe 

 student counts the rings on stumps or 

 at the ends of logs and determines the 

 present volume of the trees, and the 

 contents ten. twenty or thirty years 

 ago, and he predicts what the contents 

 will be ten. twenty or thirty years 



hence. ( ironping the trees together 

 according to diameter and rate of 

 growth, he can jjredict future yields on 

 a given acre or on a largc-r tract. 



The conrse in Snrxiyiiig begins in 

 the Necon<l and eoiitinni'-- throngh the 

 third year. The forestry .-tudent i.s 

 made familiar with the general jirin- 

 ciples of surveying and the instruments 

 used, such as the com])ass. chain, plane- 

 table and transit, with ]jractice in their 

 use. The student in his second year 

 also learns how the earth has beoi 

 made as well as the making of the 

 trees that grow u])on it. The origin 

 of the various Canadian roi k forma- 

 tions is described and their di>tribL'tion 

 is determined. At the same time he is 

 taught tt) distinguish at sight the com- 

 mon minerals and rocks. The ctjurse 

 in Chemistry is continued from the first 

 year, and the course in tree descni'tion 

 and identification extends down 

 through the shrubs and other woody 

 plants that are found growing beneath 

 the forest. 



The second year students in their 

 summer work usually get positions of 

 increased responsibility— and they get 

 more pay. 



\\'e have now gotten the student half 

 way through his course, and we \vill 

 leave him there until next month's 

 issue.
