Clarendon Mineral Spring is situated at Clarendon, Kockingham 

 County, Vt., and is owned and operated by the Clarendon Mineral 

 Spring Co. It was inspected November 22, 1907, samples directly 

 from source being obtained for the examination. The flow was said 

 to be approximately 20 gallons per minute, with a temperature of 

 49 F. The chemical analysis shows this to be a highly mineralized, 

 calcic, magnesic, bicarbonated water of the alkaline type. The hy- 

 pothetical combination indicates that approximately 90 per cent of 

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

 magnesium. The sanitary analysis shows only a trace of free am- 

 monia, small quantities of albuminoid ammonia and nitrates, with a 

 low bacterial count, which indicates organic purity. Inspection of 

 the premises failed to reveal any probable source of pollution. The 

 advertised analysis made in 1899 differs largely from the analysis 

 made in this bureau.
