DISCUSSION AND CORBESPONDENGE 



THE PROCEEDINGS OF THE ASSOCIATION OF 

 OFFICIAL AGRICULTURAL CHEMISTS 



To THE Editor of Science : The Proceedings 

 of the Association of Official Agricultural 

 Chemists for 1907 have just been published 

 as bulletin No. 116 of the Bureau of Chem- 

 istry, U. S. Department of Agriculture. By 

 order of the printing committee of the de- 

 partment, the portion of the Proceedings re- 

 ferring to the report of the committee on the 

 president's address, 1906, has been omitted in 

 the bulletin, as was also the president's ad- 

 dress itself in the printed Proceedings for the 

 preceding year (bulletin No. 105, Bureau of 

 Chemistry, U. S. Department of Agriculture). 



It may be stated in explanation of these 

 omissions that the president's address de- 

 livered at the annual convention of the as- 

 sociation, October, 1906, among other matters, 

 discussed recent publications of the Bureau of 

 Soils of the U. S. Department of Agriculture 

 and took decided issue with views set forth 

 therein. The president's address having been 

 published elsewhere (see below), it would seem 

 only right that members of the association 

 and men of science in general, who are in- 

 terested in the questions at issue, or in the 

 larger question of the liberty of free speech, 

 shall be given an opportunity to become ac- 

 quainted with the report of the committee; 

 on behalf of the committee, I would ask, 

 therefore, that the enclosed portion of the 

 proceedings of the association referring to the 

 report, as prepared by the secretary of the 

 association, be printed in Science.
