AMERICAN FORESTRY 



trees were cut $8.18, representing an investment of 

 $"^3.;J5 or an investment plus interest of $96.59. Cut at 

 that age, the lumber yield per acre would be 17,000 board 

 feet, valued at $i;JG, of which $39.41 would be net 

 profit. By the same process, the net profit at the age 

 of forty years would be $62.42, at the age of forty-five 

 years $80.59, at the age of fifty years, $140.25. The 

 ma.ximum yield comes at fifty years. The trees would 

 continue to grow after that time, so that the total yield 

 in board feet at sixty-five years would be 46.200 board 

 feet per acre, as against ,'57,600 board feet at fifty years; 

 but com[X)und interest would grow still faster at that 

 age, and the net profit would be less in sixty-five years 

 than in fiftv vears. 



In the light of these measurements, can it be said that 

 forest building and forest improvements are interest-; 

 adapted only to the rich? At present prices on lumber, 

 a pine plantation is a 6 or 7 per cent investment in 

 Massachusetts, but an increase in stumpage values of 

 whatever per cent will make a corresponding increase in 

 the returns. Young men who plant forests today can 

 begin to look for profits at once if they plant for specu- 

 lative purposes, as the land commands a higher price in 

 the real estate market after a growth of trees is estab- 

 lished upon it than before it is planted, and profit from 

 the sale of lumber begins at the end of thirty years, when 

 the stumpage value will have caught up with the cost, 

 taxes and interest.

Love of Shade Trees 



By Mrs. Emmons Crocker 



MRS. EMMONS (.ROCKI-.K 



Ex-Chairtnan of Conservation, General Federation Women's Clubs and 

 \'ice-I*resident of the American Eorestry .Association. 



A SIDE from the grateful shade on a 

 / \ hot summer day, few persons ap- 

 * * preciate the value of trees on city 

 streets. They do not realize to what an 

 extent trees cool the atmosphere in hot 

 weather and, still more important, how 

 they purify the air by absorbing the gases 

 exhaled by man and animal and givi?ig 

 out large quantities of oxygen which ani- 

 mal life requires. 



Lavish is the praise due the American 

 Forestry Association for the work it has 

 done in dealing with the great question 

 of forestry in helping to preserve the 

 integrity of the national forests and us- 

 ing its influence to acquire new tracts 

 important to the welfare of the people; 

 in encouraging the organization of state 

 forestry associations to look after the 

 interests of the commonwealths. 



Now it has taken up the more intimate 

 question of city trees because, although 

 in some states this phase is well in hand 

 llirougli state organizations that have in 

 turn founded city and town societies for 

 ihc care and planting of trees in the 

 streets, there are others that are in diro 

 need of its assistance. 



It cannot receive too hearty support 

 in this new undertaking. 



I hope that all who are invited will 

 consider it a privilege an act of patriot- 

 ism -to become members of the Ameri- 

 can Forestry Association and thereby aid 

 in sustaining the great service it is ren- 

 dering the nation.
