The Missisquoi Spring is situated at Sheldon, Franklin County, Vt., 

 and is owned and operated by the Missisquoi Mineral Spring Co. 

 The spring was inspected November 21, 1907, samples from source 

 being obtained for examination. The flow was approximately 1 quart 

 per minute, with a temperature of 44. The chemical analysis shows 

 this to be a rather highly mineralized, calcic, magnesic, bicarbonated 

 water of the alkaline type. The hypothetical combination shows that 

 approximately 83 per cent of the salts in solution are in the form of the 

 bicarbonates of calcium and magnesium, with small amount of sul- 

 phate of sodium. The sanitary analysis shows but little organic 

 matter, with only a small number of bacteria, which indicates organic 

 purity. Inspection of the premises failed to reveal any probable 

 sources of pollution. The advertised analysis made in 1888 varies 

 considerably from that made by this bureau, the mineralization of the 

 spring having increased since the former analysis was made.
