ARTHUR WOODBURY EDSON. 

 On Friday, June 23, Mr. Arthur Woodbury 

 Edson, of the Bureau of Plant Industry, 

 United States Department of Agriculture, 

 died suddenly at Waco, Texas. The news of 

 Mr. Edson's death came as a complete surprise 

 and shock to his colleagues and friends in the 



department. The members of the Bureau of 

 Plant Industry who had been closely asso- 

 ciated with him held an informal meeting on 

 Saturday afternoon, June 24, and passed reso- 

 lutions of condolence and sympathy for his 

 bereaved wife and parents. Dr. Erwin F. 

 Smith, Dr. H. J. Webber and others gave 

 expression to their regard for the man and 

 their admiration of his scientific work. 



Mr. Edson received his training in botany 

 and in agricultural science at the University 

 of Vermont, studying under Professor L. R. 

 Jones and receiving the degrees of bachelor 

 and master of science. Professor Jones early 

 discovered his great promise, as he showed 

 from the first great aptitude and enthusiasm 

 for scientific work. While at Vermont he 

 devoted a great deal of attention to the prob- 

 lems connected with the sap flow of the sugar 

 maple. The bulletin upon that subject pub- 

 lished a year ago by the Vermont Agricultural 

 Experiment Station is based largely upon Mr. 

 Edson's studies and experiments. 



On July 1, 1901, Mr. Edson was appointed 

 a scientific aid in the Bureau of Plant In- 

 dustry, Department of Agriculture, entering 

 at once upon plant breeding work, and assist- 

 ing Dr. H. J. Webber in the breeding of long- 

 staple upland cottons in South Carolina. 

 Subsequently, Mr. Edson was promoted to the 

 position of assistant physiologist, and was 

 g^ven charge of the plant breeding work upon 

 cotton in Texas and adjacent states. When 

 the plant breeding laboratory was called upon 

 to cooperate with other organizations in the 

 department in the cotton boll weevil investi- 

 gations, Mr. Edson was entrusted with the 

 direction of that part of the work. At the 

 time of his death he had made great progress 

 in producing not only earlier maturing varie- 

 ties of cotton which escape the worst ravages 

 of the pest, but varieties adapted to conditions 

 in Texas having other desirable characters, 

 such as greater yield, longer staple, larger 

 bolls and easier picking qualities. Much as 

 he had already accomplished along this line, 

 he gave promise of even greater achievements, 

 had not his untimely death cut short his work. 



In view of Mr. Edson's many valuable quali- 

 ties as an earnest and capable investigator, as
