CHEMISTRY AND CANADIAN AGRICUL- 

 TURE "■ 

 To me has been accorded the honor of 

 participating in the welcome which is being 

 offered to the members of this society at 

 this, their first, meeting on Canadian soil. 

 At any time and under ordinary circum- 

 stances it would have afforded me— as in- 

 deed any citizen of Canada— very great 

 pleasure to give you a hearty greeting. 

 Your presence here is evidence of the good- 

 will and friendly feeling that exist be- 

 tween the chemists of the United States and 

 those of Canada, and we are proud to have 

 gathered here in convention representatives 

 of that great chemical body that includes 

 in its membership men from all parts of 

 the North American continent. Chemists, 

 I have always believed, are to be numbered 

 among the men whose work makes for the 

 welfare of their country and they know no 

 political boundary lines in the giving out 

 of the results of their labors. I know that 

 we in Canada have benefited largely by the 

 work of the chemists of the experiment 

 stations in the United States. 



But the pleasure of having you here and 

 in some small way reciprocating the favors 

 you have so often showered upon us is en- 

 hanced in the gieat satisfaction we feel that 

 you should visit the Dominion at a time 

 when our country is so prosperous. At no 

 previous stage in its history has there been 

 the same substantial, steady progress and

 cultural Chemistry at the Toronto meeting of the
