In it were vast tracts of open timber lands that were quite free from underbrush, and admirably fitted for hunting.

This country was, however, much broken, and contained many dangerous "sink holes." In speaking of this section, and in describing these "sink holes" to the Elmers one evening, Mr.March had said, "Sinks, or sink holes, such as the country to the east of this abounds in, are common to all limestone formations.

They are sudden and sometimes very deep depressions or breaks in the surface of the ground, caused by the wearing away of the limestone beneath it by underground currents of water or rivers.

In most of these holes standing water of great depth is found, and sometimes swiftly running water.

I know several men who have on their places what they call 'natural wells,' or small, deep holes in the ground, at the bottom of which flow streams of water.
