one of the first organizers of this association in 

 1872, its congratulations on his continued enjoy- 

 ment of health and its joy and pleasure in being 

 able to illustrate the outcome of his eflEorts and 

 those of his colleagues in the present prosperity 

 of the association, which has expanded until it rep- 

 resents the public health interests of four coun- 

 tries and of one hundred and twenty-five million 

 people. 



Sesolved, That the association wishes Dr. 

 Stephen Smith all of the happiness which the con- 

 templation of a life spent in public service for the 

 amelioration of the sufferings of mankind may 

 bring. 



The St. Lawrence River system is iuterna- 

 tional, and new questions arise almost every 

 year with respect to the proper division of au- 

 thority over and the use of this great source 

 of water supply. An important report, re- 

 cently issued by the United States Geological 

 Survey, entitled " Surface Water Supply of 

 St. Lawrence Eiver Basin, 1913" ("Water- 

 Supply Paper 354), by 0. C. Covert and W. 

 G. Hoyt, contains results of steam-flow meas- 

 urements made in the St. Lavsrrence River 

 basin during the year 1913. The report in- 

 cludes measurements on rivers emptying into 

 the St. Lawrence by way of Lake Ghamplain 

 and the Richelieu in New York and Vermont. 

 The diversion of water for the development 

 of power at Niagara has recently claimed the 

 attention of both the countries interested, and 

 another question quite as important now is 

 that of the propriety of permitting the city of 

 Chicago to divert large volumes of water from 

 Lake Michigan through its drainage canal 

 into Illinois River. By reason of the prospec- 

 tive decrease in the depth of navigable water- 

 ways, especially those between Lakes Michigan 

 and Huron, and between Lakes Huron and 

 Erie, protests have been made by the Cana- 

 dian aiithorities. The two questions men- 

 tioned illustrate the importance of determining 

 accurately the amount of water supplied to 

 the Great Lakes and St. Lawrence system by 

 the tributaries within the United States, be- 

 cause international questions may at any time 

 arise in settling which data of this kind may 

 be of the utmost importance. Water- Supply 

 Paper 354 is the latest of a series of similar 

 annual volumes covering measurements on the 



principal streams of the St. Lawrence basin. 

 The work done in Minnesota, New York and 

 Vermont was in cooperation with the state 

 authorities. A copy of the report may be ob- 

 tained on application to the Director of the 

 U. S. Geological Survey, Washington, D. C.
