with iii Wiltshire, he argues at least dan^ 

 geroiisly. The springs in Wiltshire arei, 

 for the most part, chalk-springs, and fully 

 charged with a solution of chalk. If a 

 glass full of this water be suffered to remain 

 at rest for two or three hours, a large de- 

 posit of chalk will be made, which is 

 known in this state of solution to be very 

 fertilizing to land. But I am not satisfied 

 with this superior excellence even of the 

 Wiltshire clean-water ; for if it will pro- 

 duce as great a quantity of grass as water 

 that contains the wash of a village, (which 

 I am confident it never will cceteris pari- 

 bus J, yet it will never raise grass equal in 

 quality to that of the turbid- water crop. 

 I am not contented with quantify, 1 want 

 grass that cattle will eat. I shall not sub- 

 mit to the decision of Mr. Smith's " ju- 

 " dicious observer ;" I shall introduce an 

 animal far surpassing man in discernment
