scientific men, and yet he will go down in forestry history as the 

 greatest master of silviculture of this country, because for the 

 first time he brought together in one book and in a definite way 

 the foundation principles of silviculture and that upon the only 

 true basis, that of natural relationships. It is safe to predict that 

 his book upon silviculture will continue to be an authority wher- 

 ever the foundation principles of the subject are studied or taught. 

 Dr. Mayr's death is an irreparable loss to silviculture, not only 

 in Germany, but throughout the world and the many foreign 

 students who have been enthused with the man's tremendous 

 energy and ability, feel his loss almost as personally as the wife, 

 sons and daughters who formed with him an unusually attractive 

 and sympathetic home. May the son who is following him in 

 forestry carry on the work continued so ably over so long a 

 period, and perfect and apply the results of the splendid Forest 

 Experiment Station at Grafrath, which should be given Dr. 

 Mayr's name.
