In the course of evaporating the waters, it was not unusual for them to give off odors 

 which showed rather too plainly that they contained a disagreeable quanity of animal 

 matters in solution. In one instance the room and adjacent hall were filled with the odor 

 common to stables, and yet this water is in constant use both for cooking and drinking. 



Another well is quite remarkable for the amount of solid matter contained in its waters. 

 We obtained from one gallon 245 - 76 grains of solid matter, after a large amount of ferru- 

 ginous mailer had separated in the form of a precipitate. It consisted of protoxide of iron 

 and carbonate of lime : a trace of magnesia and the sulphates, only, was detected in the 

 water. 



It is evident from the numerous analyses which Lave been made of the waters of the 

 Tertiary or Albany clay, that these waters are not only hard, but frequently are so highly 

 charged with mineral substances as to be unfit for domestic purposes. Another object for 

 which they are not at all adapted, is for the generation of steam for moving machinery : 

 it has been found in practice that they can not be employed for this purpose, as the boiler 

 l- rapidly destroyed under their use. 



The springs which issue from the upper part of this formation, are much better adapted 



to the purposes of life. The water of the Patroon's creek contains only 3" 12 grains of saline 



>ter per gallon ; in addition to this, 1 • 60 of organic matter was found, making the solid
