��A Well That Supplies Two Kinds of Water

��salt or sulphur?"

This question is appro- priate when one does "the honors" at a well at We- laka, Florida, for two kinds of water are "on tap" there.

The well first was drilled to a depth of one hundred and sixty feet. Here or- dinary "sulphur" water was encountered. The drill was then carried to a depth of three hundred feet. Here a strong min- eral water was struck. In order to use both kinds of water, a small tubing was passed through the upper casing of four-inch pipe and down nearly to the bottom of the well. Both this and the outer casing were connected with pumps. A favorite joke is to give visitors a drink of the weaker water in the first glass and then replace it with the brine in the second.

The United States Geo- logical Survey has records of only about six wells of this kind in the country, but there is no reason why similar wells can not be ob- tained in regions where the waters in the upper strata differ from those lying deeper.

At Mulford, Utah, there is a "double" artesian well which has a flow of thirty-seven gallons per minute of pure water from a four hun- dred and fifty foot depth and another of two gallons per minute of strong sulphur water from a depth of seven hundred and fifty feet. A four-inch casing is used on the upper level, and a two- inch pipe extends to the very bottom of the well. These "double" wells have wide uses.

���The double piping makes both the sulphur water and the salt water available

��PHOTOGRAPH- ING snakes in their native retreats is a sport often overlooked by the camera enthusiast. It not only requires a high degree of courage on the part of the photographer to ap- proach his quarry, but much time and patience must be expended before the snake assumes a posi- tion that can be readily caught by the camera. It goes without saying that photographing pois- onous snakes, such as cop- perheads, water-moccasins and rattlesnakes, should not be undertaken by a novice, unless he be ac- companied by a person familiar with the habits of such snakes.

However, it is just as much sport photographing harmless snakes. In the first place, you must know where to look for them, and secondly, having found them you must wait pa- tiently until they get in interesting poses. Water- snakes make good subjects.

���The snakes here photographed are harm- less, but they are none the less interesting
