All the older springs have been found in beds of blue marl, or clay rather, which cover the valley more or less throughout its whole extent. On digging into this clay to any considerable depth, we are pretty certain to find traces of mineral water. In some places, at the depth of six or eight feet, it has been discovered issuing from a fissure or seam in the underlying limestone, while at other places it seems to proceed from a thin stratum of quicksand which is found to alternate with the marl at distances of from ten to forty feet, below which bowlders of considerable size are found.

The spouting springs have been found by experimental boring. As this is the cheapest and more certain method, it is "the popular thing" at present, and the day may not be far distant when all Saratoga will be punched through with artesian wells reaching hundreds of feet, if not through to China, and thus an open market made for the Saratoga waters among "the Heathen Chinee."

Mr. Jessie Button, to whom we are indebted for both the Glacier and the Geyser springs, seems best to understand the process of successfully boring artesian wells, having made these his special study and profession. Like Moses of old, he strikes, or taps, the rock and behold streams of water gush forth.
