Brookville Spring No. 1..: 
A remarkably pure water from about seven miles west of 
Brookville has been examined. It is clear, colorless, and of 
an agreeable taste. It contains only 8.097 grains of solid mat- 
ter per gallon, which consists of calcium bicarbonate, calcium 
sulfate, sodium chlorid, with traces of silica, alumina, and mag- 
nesium bicarbonate. 
Another water from Brookville, which was examined in June, 
1887, contains only 3.48 grains per gallon of mineral matter. 
This consists quite largely of silica, with small quantities of 
iron and aluminum, and traces of calcium and magnesium bi- 
carbonate, sodium chlorid, and sodium nitrate. This water is 
remarkably free from mineral matter, and is in fact one of the 
purest. waters so far noticed in the state. As will be seen, it 
contains no more mineral matter than waters from the granite 
and sandstone ledges of the extreme Eastern states. 
California Spring, Norwood, Franklin County. 
This spring is on the farm of E. W. Hume, four miles north- 
west of Ottawa. It is pleasantly situated on the southern slope 
of the broad valley of the Marais des Cygnes. The flow is 450 
gallons per hour. The California spring is said to have derived 
its name from its situation on one of the numerous trails lead- 
ing across the state to the mountains and to California. On the 
unbroken prairie in the vicinity may still be seen numerous well- | 
marked trails, all converging towards this bountiful water-sup- 
ply. A few barrels of the water were shipped in 1902. That 
the water is of exceptional purity may be noticed from the 
analysis which follows:
