Cherry Hill Spring is situated at Highwood, near New Haven, 

 Gonn. It is owned by Mr. H. B. Graham. The spring was inspected 

 December 6, 1907, samples directly from source being obtained for 

 examination. The flow was approximately 10 gallons per minute, 

 with a temperature of 49 F. Chemical analysis shows this to be a 

 calcic, bicarbonated, nitrated water of the alkaline-saline type. The 

 hypothetical combination shows that of the salts in solution approxi- 

 mately 44 per cent are in the form of the bicarbonate of calcium, 

 20 per cent of sodium nitrate, and smaller amounts of magnesium 

 salts. The sanitary analysis shows only a small quantity of albumi- 

 noid ammonia and a rather large amount of nitrogen in the form of 

 nitrate, while the bacterial count is low. Inspection of the premises 

 failed to reveal any probable sources of pollution. No advertised 

 analysis of this water could be obtained for purposes of comparison.
