LETTER OF SUBMITTAL 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington, D. C., January 30, 1911. 



SIR: I have the honor to submit for your inspection and approval 

 a manuscript giving some of the results of an investigation conducted 

 by Mr. W. W. Skinner, Chief of the Water Laboratory of the Mis- 

 cellaneous Division, on the character of American mineral waters as 

 sampled at source. This is the first of a series of bulletins to be issued 

 on this subject and includes only waters from the New England 

 States. The investigation is of great importance to the public, 

 especially to physicians who desire an absolutely reliable statement 

 as to the character of a water when prescribing its use. The waters 

 examined are those reported in Mineral Eesources, published by the 

 United Stated Geological Survey. From time to time as other springs 

 develop additional data will be issued. The Hydrographic Branch of 

 the Geological Survey, under the direction of Mr. M. O. Leighton, 

 cooperated in the work to the extent of collecting most of the samples. 

 Credit is also due Messrs. W. D. Collins and D. C. Dyer, of the Water 

 Laboratory, who assisted in the analytical work. 



I recommend that the report be published as a bulletin of this 

 bureau. 



Respectfully, J. K. HAYWOOD, 



Chief Miscellaneous Division. 

 H. W. WILEY, 



Chief Bureau of Chemistry.
