The well from which (3) was taken is about 1500 feet from 

 Oak Orchard creek, with the ground surface only a few feet above 

 the water level in the creek. The elevation of water in Oak 

 Orchard creek directly opposite is substantially the same as in 

 the well, and when pumping from the well the water is drawn to 

 about 5 feet below the level of the water in the creek. Neverthe- 

 less, analyses (3) and (4) show that the quality of water in the 

 well is quite different from that in the creek. In the case of the 

 water from the well, permanent hardness is only 4°, while the 

 water from the creek shows 17°, although it is difficult to under- 

 stand, under the conditions, how the source of water in the well 

 can be other than that from the creek — the more specially since 

 the underlying rock is open. In regard to the permanent hard- 

 ness of the creek water, as shown by analysis (4), it is probably 

 due to Oak Orchard creek flowing over a bed of gypsum near 

 Oakfield. 



Quality of Water in the Vicinity of Batavia 



In order to still further illustrate water supplies in western 

 New York, the following analyses from the vicinity of Batavia, 

 as made by Mr Eilinger, are of interest; (1) is from Devil's lake, 

 a small body of water ten or twelve miles west of Batavia; (2) is 

 from Mill springs, five miles north of Batavia; (3) is from Ham- 

 ilton springs, two miles south of Batavia; and (4) is from Horse- 

 shoe lake, two and one-half miles east of Batavia. Mill springs, 

 the analysis of which contains the most total hardness, are at the 

 foot of a ridge from 100 to 150 feet in hight and probably is not 

 far from the gypsum belt, as the permanent hardness in this water 

 is difficult to account for on any other basis. Both Hamilton 

 springs and Horseshoe lake are above that belt, and accordingly 

 permanent hardness is not very serious in either of them.
