Holly Mineral Spring is situated at East Woonsocket, R. I., and is 

 owned and operated by Mr. Stephen Wilcox. The spring was 

 inspected December 2, 1907. Samples could not be obtained directly 

 from source but were taken from a lead pipe connected with a cement 

 basin inclosing the spring. The flow was approximately 40 gallons 

 per hour, with a temperature of 46 F. Chemical analysis shows this 

 to be a calcic, sodic, bicarbonated water of the alkaline type. The 

 hypothetical combination indicates that approximately 57 per cent 

 of the salts in solution are in the form of the bicarbonates of calcium, 

 magnesium, and sodium, and 17 per cent are present as chlorid and 

 sulphate of sodium. The sanitary analysis shows only a small 

 amount of ammonia and nitrates, with absence of bacteria, which indi- 

 cates organic purity. Inspection of the premises failed to reveal any 

 probable sources of pollution. The advertised analysis, which is an 

 incomplete statement of results, partially agrees with the analysis 

 made by this bureau.
