Highland Spring is situated at West Abbington, Mass., and is 

 operated by J. W. Dooten. It was inspected December 3, 1907, 

 samples directly from source being obtained for the examination. 

 The flow was approximately 5 gallons per minute, with a tempera- 

 ture of 50 F. Chemical analysis shows this to be a lightly mineral- 

 ized, sodic, calcic, bicarbonated, nitrated, muriated water of the 

 alkaline-saline type. The hypothetical combination indicates that 

 approximately 36 per cent of the salts in solution are in the form of the 

 bicarbonates of calcium and magnesium, 17 per cent of sodium 

 nitrate, 15 per cent of sodium chlorid, and 8 per cent of magnesium 

 sulphate. Sanitary analysis shows a small quantity of albuminoid 

 ammonia, with traces of nitrites, also a considerable amount of 

 nitrates, and an absence of bacteria. Inspection of the premises 

 failed to reveal any probable source of pollution. No advertised 

 mineral analysis could be obtained for purposes of comparison.
