AMERICAN FORESTRY 



trees were cut $8.18, representing an investment of 

 $23.35 or an investment plus interest of $i:l0.59. Cut at 

 that age, the lumber yield per acre would be 17.000 board 

 feet, valued at $13<J, of which $;!li.41 would be net 

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

 of forty years would be $()2.42, at the age of forty-five 



years $80.59, at the age of fifty years, $1-10.' 



The 



maximum yield comes at fifty years. The trees would 

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

 in board feet at si.xty-five years would be 4ii,300 board 

 feet per acre, as against 37,(100 board feet at fifty years; 

 but compound interest would grow still faster at that 

 age, and the net protit wnuld he less in sixty-fi\'e 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 (i 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, ^llung 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 higber price in 

 the real estate market after a gr(_)wth df 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, 

 raxes and interest.

A SIDE from the grateful shade on a 

 / \ JK.it summer day, few persons ap- 

 ^ * preciate the \alue of trees on city 

 streets. Thev do not realize to what an 

 extent trees cool the atmosphere in hot 

 weather — a)id. still mure importanr. how 

 they purif\- the air by absorbing the gases 

 exhaled in' man and animal and .givi'ig 

 nut large (|uantities of o.xygen which ani- 

 ni.d life requires. 



Lavish is the praise due the .\merican 

 l'"(irestr\- A>--ociatiun for the work it has 

 ilnne in dealing with the great question 

 I if forestry — in hel])ing to preserve the 

 integritv of the national forests .and us- 

 ing it'- influence to acquire new tracts 

 ini|iiirlant tn the welfare nf llie peuple : 

 in encouraging the organizatinn i>f state 

 forestn' assciciations to look .'ifter the 

 interests nf iIil- comnii mw ealtlis. 



Now it has taken up the mure intimate 

 (|uesti(in nf city trees because, although 

 ni scinie states this phase is well in liand 

 iln-ciugli st.ate organizations that have in 

 mm founded cit\' and town societies for 

 llie c.ire .md ])l,Lnting of trees in the 

 streets, there are others that are in dire 

 need of its assistance. 



It lanncit receive too hearl\ support 

 in this new undei^taking. 



I hope tliat all who are in\ited will 

 consider it a prixilcge — an ,icl of p.atriot- 

 ism -til liecnme members nl the .\nieri- 

 cin l''(ireslr\' .Kssnciation and thereby aid 

 in sustaining the great service it is ren- 

 dering the nation.
