The second annual meeting of the Association 

 of Official Seed Analysts was held in Boston, 

 December 28-29, 1909, in connection with the 

 meeting of the American Association for the Ad- 

 vancement of Science. 



Agricultural colleges, experiment stations and 

 state departments of agriculture in twelve states 

 and the Canadian and the United States depart- 

 ments of agriculture were represented. 



Three papers were presented as follows: 



" The Effect of Alternating Temperature, on the 

 Germination of Seeds," by W. L. Goss, U. S. 

 Department of Agriculture. 



" Importance of Uniform Methods of Seed Test- 

 ing," by A. D. Selby, Ohio Agricultural Experi- 

 ment Station. 



" The Sale of Adulterated Farm Seeds in the 

 United States," by E. Brown, U. S. Department

The greater part of the time of the meeting was 

 devoted to consideration of the reports of the com- 

 mittees on methods of seed testing and on legisla- 

 tion. The report on methods of seed testing for 

 purity was adopted as official by the association 

 and that on germination as provisional. The 

 report on state legislation was adopted and the 

 secretary was instructed to prepare both reports 

 for publication.
