view. They are of water from wells designated as B and G re¬ 
spectively. Well B was put down in May, 1897, and had been 
open for a year at the time the sample in question was taken ; well 
G was put down the day the sample was taken. Well B reached 
the gravel at a depth of 6 feet, while well G was but 4 feet deep, 
leaving about 2 feet of a difficultly pervious soil between the bot¬ 
tom of the well and the gravel. The analyses of the two samples 
follow:

§ 66. These two analyses differ slightly in the ratios of the 
respective salts to the total solids, but serve to justify the statement 
made above that the well waters may be assumed to faithfully 
represent the composition of the freely circulating waters within the 
soil to the depth of the well. This is still the case when the water
