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.

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
