THE AMERICAN FORESTRY ASSOCIATION. 



The American Forestry Association held 

 its summer meeting at Springiield, Massa- 

 chusetts, on September 4th and 5th, in con- 

 nection with the American Association for 

 the Advancement of Science. 



The President of this Association, the 

 Hon. J. Sterling Morton, Secretary of Agri- 



culture, was prevented by of&cial business 

 from attending, but sent his regards to-

 the objects of the meeting.

 tax sales be permanently held by the State 

 and devoted to the purpose of the produc- 

 tion of trees, such lands being admirably 

 adapted to this end. He spoke of the fire 

 laws of Maine and stated that the adverse 

 interests of forest owners was the great ob- 

 stacle to any reform in the proper control. 

 Under a sharp competition the land was 

 stripped of everything salable and the refuse 

 left where it happened to fall, thus ulti- 

 mately becoming through its inflammabil- 

 ity a menace to all neighboring property. 



Mr. George H. Moses, Secretary of the 

 New Hampshire Forestry Commission, re- 

 viewed the history of legislative attempts 

 to provide suitable protection to the forests, 

 and spoke of the creation of the present
