THE MINERAL SPRI>'GS OF SARATOGA 9 



flowing, well carbonated and of the same general composition as the 

 Saratoga \vaters. An analysis is given later. 



Still farther north in the village of Whitehall, thirty-nine miles 

 from Saratoga Springs, is a spring called the " Adirondack," feebly 

 carbonated and of greatly contrasted composition to the Saratoga 

 waters in that it contains less of sodium chlorid than of either 

 calcium or magnesium carbonate, and almost as much calcium 

 sulphate. The total dissolved solids is only about one-eighth or one- 

 tenth that of the Saratoga waters. (Bulletin 32, U. S. Geol. Survey, 

 pages 2^ and 32, 1886.) 



To the south the mineral waters have been discovered even beyond 

 Ballston. Thus, at Round Lake, in 1875, a drill hole was put down 

 which reached a total depth of 1403 feet. At a point below 1300 

 there was struck a flow of water of composition not unlike the 

 Saratoga waters. Its analysis is given later. The hole was tor- 

 pedoed, however, and after the explosion the flow was lost. 



In 1827, a well was even drilled in Albany 500 feet deep, on 

 Ferry street, and yielded carbonated waters of the general composi- 

 tion of those at Saratoga Springs (L. C. Beck, Mineralogy of New 

 York, 1841, page 138). An analysis is cited later. Albany is forty 

 miles from Saratoga, and respectively thirty-two and twenty-six 

 from Ballston and Round Lake. No other drilled wells have been 

 recorded in the interval from Round Lake to Albany. 



Thus waters, carbonated and of a somewhat similar composition 

 are known over a stretch of approximately forty miles in a general 

 north and south direction from Albany to Gurn springs, or if we 

 include the Adirondack springs, at Whitehall, of about sixty-five 

 miles. Between Albany and Round Lake, a distance of twenty 

 miles, none are known. And again from the Gurn spring to White- 

 hall, a distance of thirty miles, none have been reported. These 

 statements are in a measure useful in connection with general geo- 

 graphical conceptions, but they are not expressed in a way to be of 

 geological significance. The springs should be grouped in northeast 

 and southwest lines, along the known faults or fault systems. 

 Apparently then, the Ballston-Saratoga Springs-Gurn series are to 

 be taken on one line, with perhaps the Whitehall spring at the 

 extreme north. The Round Lake well is five miles to the east of 

 this line ; the Quaker springs eight miles : Reed's spring in South 

 Argyle, eight or more; and the :\lbany well nearly fifteen miles 

 east of its southern prolongation.
