La Cygne Iron Spring. 
This spring is situated on the west bank of the Marais des 
Cygnes, near LaCygne, on the property of Mr. Cheagor. The 
spring is not large, although it seems to be a good chalybeate 
water. The total solids in the water are 31.326 grains, of which 
3.9 grains are ferrous carbonate. ‘There is also a considerable 
quantity of calcium carbonate and magnesium carbonate, with 
a small quantity of calcium sulfate, sodium chlorid, and man- 
ganese carbonate. 
Clarus Spring, Batesville, Woodson County. 
This spring is situated on the Fort Scott & Wichita railway, 
nine miles west of Yates Center. The water comes from be- 
neath a thick limestone ledge. [From the situation of the 
spring, it is probable that there is no opportunity for the water 
to become in any way contaminated by organic matter. The 
water, as will be seen by the analysis, belongs to that class of 
pure waters which are recommended by physicians on account 
of the fact that they contain so small a quantity of mineral 
salts. For some time this water was kept on tap at one of the 
drug-stores in Topeka. 
IMPROVEMENTS. 
This spring is walled up and cemented, and a small spring- 
house has been built over it. The flow is about forty gallons 
per hour. The analysis is given in chapter XVIII. 
Lawrence City Water, Douglas County. 
The water supplied to the city of Lawrence is practically a 
chalybeate water. It is obtained from a large well dug in the 
sand a short distance west of the river, and from points that 
have been driven into the soil in the vicinity. The water, after 
it is pumped, is aerated by flowing from the top of a pipe sev- 
eral feet into a reservoir, and it is then allowed to stand in set- 
tling basins for some time. ‘This treatment, however, does not 
fully remove the iron, for, soon after the water is drawn from 
the service-pipes, it loses its carbon-dioxid gas, becomes par-
