The Mohican Spring is situated about 5 miles from Bridgeport, 

 Conn. The spring was inspected December 5, 1907, samples directly 

 from source being obtained for examination. The flow was approxi- 

 mately 30 gallons per minute, with a temperature of 43 F. The 

 chemical analysis shows this to be a lightly mineralized, sodic, calcic, 

 bicarbonated water of the alkaline type. Hypothetical combination 

 indicates that approximately 51 per cent of the salts in solution are in 

 the form of bicarbonates of calcium, magnesium, and sodium, with 

 smaller amounts of the sulphate and chlorid of sodium. Sanitary 

 analysis shows only a small amount of albuminoid ammonia and ni- 

 trate, which, with a very low bacterial coun.t, indicates organic purity. 

 Inspection of the premises failed to reveal any probable sources of 

 pollution. The advertised analysis made in 1904 is in fairly close 

 agreement with that made by this bureau, with the exception of sodiun 

 and chlorin, which have apparently decreased since the former analy- 

 sis was made.
