ON THE ANALYSIS OF THE WATER OF A FLOWING 
ARTESIAN WELL AT MARINETTE WISCONSIN.

The mineral matter contained in the water of the well de¬ 
scribed below differs so widely from that of other similar wells- 
in Wisconsin which I have analyzed that it seems worthy of 
being made a matter of record. 
The following facts relating to the history of the well are 
kindly furnished me by Hon. Isaac Stephenson. 
“The well was drilled in August, 1895, on my residence prop¬ 
erty in the city of Marinette. The shaft passes through lime 
rock, light and reddish sandstone and narrow strata of slate for 
the first two hundred feet. We first struck water in a lime¬ 
stone crevice at a depth of four hundred and five feet. It was 
quite a flow. We then drilled five feet more and struck another 
crevice with a greater flow. We continued drilling through 
limestone, sandstone and slate to a depth of seven hundred and 
sixteen feet when we struck granite and stopped. There is no 
flow below four hundred and ten or fifteen feet.” “We put 
packing down at a depth of four hundred and fifty-seven feet, 
fearing that the water might escape below. Then we piped 
with four inch pipe with packing down three hundred and 
thirty-three feet. The water then raised to a height of twenty- 
one feet above the surface, and comes from the limestone” be¬ 
tween four hundred and four hundred and twenty feet below the 
surface. 
Mr. Stevenson also reports the temperature of the water as 
49° F., and that (Feb., 1896) “the water continues to flow as 
rapidly as at first. ”
