Sand Spring is situated in Berkshire County, near Williamstown, 

 Mass., and is owned by Dr. S. L. Loyd. It was inspected November 

 30, 1907, samples directly from source being obtained for the examina- 

 tion. The flow was said to be 400 gallons per minute and at the 

 time of inspection the temperature was 76 F. This is a thermal 

 water and the only hot spring inspected in the New England States. 

 Chemical analysis shows it to be a moderately mineralized, calcic, 

 bicarbonated water of the alkaline type. The hypothetical com- 

 bination indicates that approximately 78 per cent of the salts in 

 solution are in the form of the bicarbonates of calcium, magnesium, 

 and iron, with a small amount of the sulphates of sodium and mag- 

 nesium and the chlorids of sodium and potassium. The sanitary 

 analysis shows a small amount of albuminoid ammonia and nitrates, 

 while the bacterial count, though slightly high, is not abnormally so. 

 Inspection of the premises failed to reveal any probable source of 

 pollution. The advertised analysis made in 1896 shows less salts 

 in solution than were found in the sample examined by the Bureau 

 of Chemistry.
