were formerly crowding these young 

 oaks; the other is a big mixture, with 

 about nineteen white oaks to the cruis- 

 ing mile, most of them choked and de- 

 formed by pin oaks and red oaks with 

 their faster growth and bigger leaf area. 

 The first woodlot is worth about twice 

 as much as the second, just as it stands. 

 It is really wonderful how quickly a tree 

 will push out and fill all the available 

 space you clear for it in a forest, for the 

 natural crowding and competition is 

 fearful and every tree is ready and 

 equipped to take advantage of the least 

 accident to its neighbors to get ahead 

 and do some big growing. It is the 

 crowding that keeps all our forest trees 



about of a single height and diameter; 

 most of them could do better if the 

 others would give them a chance. This 

 is the work that you must do with the 

 axe to push along your desirable trees, 

 and you will be surprised at the sudden 

 increase in height and trunk diameter 

 that follows a judicious thinning. 



In our next chapter will be presented 

 some details on private nurseries for 

 special deciduous trees, and the best 

 methods of combating the attacks of 

 fire, fungus and insect enemies, as prac- 

 ticed in the forest of a large country 

 estate.

AMERICAN FORESTRY ASSOCIATION EXHIBITS 



THE American Forestry Associa- 

 tion will have attractive ex- 

 hibits of the work it is doing at 

 the Forest Products Exposition, 

 to be held in the Coliseum, Chicago, 

 April 30th to May 9th and in the Grand 

 Central Palace, New York, May 21st 

 to May 30th. 



Gradually the Forest Products Expo- 

 sition is shaping itself definitely. Vari- 

 ous associations are making more or 

 less elaborate plans; large and small 

 concerns are preparing for active demon- 

 stration of the value and merits of 

 their wares and their specialties; the 

 Forest Service of the U. S. Department 

 of Agriculture is assembling a demon- 

 strating exhibit that will probably be 

 the most enlightening and interesting 

 display of the sort ever given ; the wood- 

 working machinery people are polishing 

 up the machines that in their operations 

 will show the last degree of efficiency 

 and mechanical advancement, and there 

 is every reason to justify those in touch 

 with the actual preliminary details in 

 predicting one of the most representa- 



tive, attractive and generally important 

 industrial expositions ever given in this 

 country. Special arrangements have 

 been completed for the speedy yet un- 

 hurried transfer of the Chicago exhibits 

 to New York; both expositions will be 

 installed and handled by the same force 

 of men; the moving picture exhibit in 

 connection with both expositions will 

 contain wonderfully accurate views of 

 activities in every branch of the wood 

 industry, a large attendance of manu- 

 facturers, producers, specialists, en- 

 gineers, architects, contractors, build- 

 ers, buying and selling forces, educa- 

 tionalists, the mechanical forces of the 

 factory, the mill and the shop, organiza- 

 tions and individuals representing every 

 branch of the industry and the great 

 power, the home builder, street im- 

 provement voter, investor in improve- 

 ments in building, the layman, the 

 ultimate consumer, will go to Chicago 

 and to New York to study the actuali- 

 ties and see the proofs and observe the 

 multitude of things they never dreamed 

 of, according to every indication. 



In trying to find uses for blight-killed chestnut it has been found that it can not be utilized for 

 crating stone; quarry owners say that chestnut wood leaves an indelible stain on the marble or granite. 



Railroads caused nearly half the forest fires in Colorado and Wyoming last year, and almost 

 one-sixth -were set by lightning. In California lightning started more than half, with railroads a 

 comparatively insignificant cause.
