In calling this meeting to order, I wish 

 first to say a few words about the services 

 performed by the committee on organization 

 — and I am sure none of them will think 

 it invidioiis if I refer particularly to the 

 work of the secretary, Professor Lovejoy, 

 who has borne the heat and labor of the day 

 more than any one else. All of its members 

 are busy men and the work they have done 

 is a labor of love. It is but fair to them 

 that it should be known to all that their 

 labors, continued for over a year, have been 

 singularly free from a disposition on the 

 part of any one to push a particular scheme 

 or ride a particular hobby. If any one, 

 perchance, has come here to-day with a fear 

 that something is to be sprung upon the 

 meeting, or that the committee has, as the 

 saying goes, something up its sleeve, pray 

 let him disabuse himself of the idea. The 

 committee has tried to do nothing more 

 than had to be done to bring together a 

 representative body, without reference to 

 factions or sections; to get matters into 

 shape to facilitate discussion and economize 

 time. 



Doubtless we have made mistakes. But 

 they are only such as are incident to get- 

 ting a large enterprise under way, espe- 

 cially considering the lack of authoritative 

 precedents to follow, and the lack of such 

 clerical and other machinery as the organi- 

 zation itself will bring into being. The 

 committee found itself between the Seylla 

 of doing nothing definite and the Charybdis 

 of doing so much as to forestall action that
