Equinox Spring is situated near Manchester, Vt., and is owned and 

 operated by the Equinox Spring Water Co., large quantities of the 

 water being bottled for sale. The spring was inspected on November 

 22, 1907, samples directly from source being obtained for examina- 

 tion. The flow was approximately 60 gallons per minute, with a 

 temperature of 44 F. Chemical analysis shows this to be a moder- 

 ately mineralized, calcic, bicarbonate water of the alkaline type. 

 The hypothetical combination shows that approximately 41 per cent 

 of the salts in solution are the bicarbonates of calcium and magnesium, 

 with smaller amounts of bicarbonate and sulphate of sodium. The 

 sanitary analysis shows only traces of organic matter and a small 

 amount of nitrate, with an absence of bacteria, which determines the 

 water to be of high organic purity, while inspection failed to reveal 

 any probable source of contamination. The advertised analysis 

 made in 1892, with the exception of silica and chlorin, agrees fairly 

 well with the analysis of this bureau.
