TWENTY-NINTH ANNUAL MEETING. 89 
The presence of nitrites, nitrates, phosphates, and chlorides made me suspect 
’ that possibly the water was contaminated with surface or sewage waters. This 
suspicion was confirmed when a day after a heavy rain the flow of water was per- 
ceptibly increased. 
However, when the springs issue from shale beds they are usually weaker in 
flow, and the waters leave a stain of iron along their course, and at times show a 
slight: iridescent film on their surface. 
When wells are put down about Atchison to a depth of 200 to 300 feet, the wa- 
ter obtained is salty. In the western part of the city, in part of Mr. Peter Beck- 
er’s property on West Main street, there is such a well 325 feet deep. The water 
from this well is too salty to drink. When first drawn it is surcharged with car- 
bon dioxide gas, and is perfectly clear. But as the gas escapes the water becomes 
turbid with a precipitate of iron oxide. The analysis of this water stated in parts 
per 1,000,000 resulted as follows:

About 214 miles north of Centralia, in Nemaha county, is a well 125 feet deep, 
the water of which is highly charged with sulphate of lime. Whether this 
argues gypsum deposits at that depth we will not state. The analysis of the 
water is as follows, stated in parts per 1,000,000 :
