3. Water of artesian wells in the Triassic. All the artesian wells dug 

 in the valley have much saline matter in solution. I was informed by 

 Prof. C. U. Shepard, as the result of his analysis of the water of tlie South 

 Hadley well, that common salt was present in large amount, and the abun- 

 dance of the salt pseudomorphs in the sandstones in which the well was 

 bored indicates that this comes from the sea water entangled in the sand- 

 stones at the time of their deposition. The appended analysis of a sample 

 from the more northern well shows that the water has nearly the constitution 

 of a bittern. One United States gallon of water contained in solution 102.54 

 grains of saline matter, which consisted of the substances named below. 



Analysis hy Prof. C. A. Goessmann of one gallon of water from the artesian well at the 

 Montague Paper Company''s mills at Turners Falls, Massachusetts; made at 

 Amherst, November 2, 1874.
