Goulding Spring is situated about 1 mile from Whitman, Mass., 

 and is owned and operated by Goulding Bros. The spring was visited 

 December 3, 1907, samples directly from source being obtained for 

 examination. The flow was approximately 3 gallons per minute, 

 with a temperature of 50 F. Chemical analysis shows this to be 

 a moderately mineralized, sodic, calcic, bicarbonated, muriated, 

 nitrated water of the alkaline-saline type. Hypothetical combina- 

 tion indicates that approximately 31 per cent of the salts in solution 

 are in the form of the bicarbonates of calcium and magnesium, 17 

 per cent of sodium nitrate, 13 per cent of sodium chlorid, and small 

 amounts of the chlorid and sulphate of magnesium. Sanitary analy- 

 sis shows only a small amount of albuminoid ammonia and quite a 

 large amount of nitrate, but an absence of bacteria. No advertised 

 analysis could be obtained for purposes of comparison.
