THE ASSOCIATION'S EXHIBIT 



MEMBERS of the American 

 Forestry Association, their 

 friends, and all who are inter- 

 ested in forestry, all who love 

 trees whether in great forest areas, 

 woodlands, country estates, the garden 

 or the street, are invited to visit the 

 exhibit of the Association at the Grand 

 Central Palace, New York City, May 

 20 to 30, during which period the For- 

 est Products Exposition will be held. 



This will be the same exhibit which 

 the Association had at the Exposition in 

 Chicago from May 1 to May 10 and 

 which thousands of Chicagoans and 

 others visited. Attendants will explain 

 the work of the Association and dis- 

 tribute literature as well as tell of the 

 value of the great educational work the 

 Association is doing. The chief feature 

 is the display of photographs showing 



different phases of forestry, the cutting, 

 logging, and marketing of mature trees, 

 the protection of the forests from fire, 

 insect and disease; the replanting of 

 forest land; the instruction of forest 

 students, with examples of the losses 

 due to lack of scientific forest manage- 

 ment in short, every condition in the 

 use, the development, the protection and 

 the growing of trees. 



A souvenir given to each visitor is a 

 circular containing forest scenes in 

 colors and this was eagerly sought and 

 highly commended at Chicago. Copies 

 of the magazine AMERICAN FORESTRY 

 are also given away. It is especially 

 desired that school teachers and children 

 should visit the exhibit. It is to be on 

 the second floor of the Grand Central 

 Palace, near the middle of the hall. 



WHAT IS A SHADE TREE WORTH? 



OW many people know what a 

 shade tree is worth? How 

 many ever give a thought to its 

 value? Its grateful shade is 

 enjoyed, its beauty is appreciated, both 

 in a general sense, but few perhaps ever 

 stop to think of its actual cash value. 

 Perhaps this is never brought home 

 more forcibly to a man than when a 

 shade tree in front of his residence, a 

 tree of which he is proud, is damaged 

 or destroyed. Then ask him its cash 

 value. He is likely to measure it by 

 his own sense of what the tree has 

 meant to him. Not unnaturally he may 

 declare the tree worth hundreds of dol- 

 lars to him. He will tell you what is 

 only too apparent, that it cannot be re- 

 placed at once for thousands of dollars. 

 It will take years to grow a similar tree 

 on the same spot. 



It was somewhat startling to the peo- 

 ple of Ann Arbor, Michigan, to learn 

 from the recent report of their city en- 



gineer that the shade trees of the city 

 are valued at $290,000. This is over 

 a quarter of a million dollars' worth of 

 property which the average man might 

 never consider in giving an estimate of 

 the city's wealth. 



Prof. Filibert Roth, of the Forestry 

 Department of the University of Michi- 

 gan, was asked to give the valuation, and 

 his report names this modest sum. For 

 the purpose of estimating the value of 

 the trees and shrubs owned by the city, 

 it was assumed that trees stand two rods 

 apart throughout the residence sections 

 of the city. According to Professor 

 Roth, a tree is worth $10 when it is 

 nicely established and is four inches in 

 diameter at a point breast high. Figur- 

 ing the compound interest at five per 

 cent, this $10 has grown into $20 in 

 only 18 years. All trees are figured on 

 this basis, since hundreds of them might 

 be rated at more than $100 apiece. It 

 is estimated that there are in Ann Arbor
