Pack Monadnock Lithia Spring is situated at Temple, N. H., and 

 is owned and operated by S. A. Scammon. It was inspected Novem- 

 ber 27, 1907, and again February 24, 1910, samples from source 

 being obtained for the purpose of examination. The flow of this 

 spring is approximately 2 gallons per minute, with a temperature of 

 43 F. The chemical analysis shows it to be a lightly mineralized, 

 sodic, calcic, bicarbonated water of the alkaline type. The hypo- 

 thetical combination indicates that approximately 36 per cent of the 

 salts in solution are the bicarbonates of calcium and magnesium, 10 

 per cent sodium bicarbonate, 9 per cent sodium sulphate, and 7 per 

 cent sodium chlorid. The sanitary analysis shows only a trace of 

 free ammonia, small quantities of albuminoid ammonia and nitrites, 

 and a very low bacterial count. Inspection of the premises failed to 

 reveal any probable sources of pollution. The analysis made in this 

 bureau differs very markedly from the advertised analysis, the latter 

 failing to represent the character of the water from source. The 

 difference between the two analyses is wholly inexplainabls.
