remaining in the pond was too fmall to make :«hy 

 confiderable trial with. Determined, however, to 

 afcertain the truth or fallacy of my conjcdlure, in 

 the latter end of July 177a, I meafured out two 

 fpots of fifty fquarc yards each, in an adjoining mea- 

 dow, which had been mowed, and was much burnt 

 up. And in order to prove how far tliis exceeded 

 other water, I watered one fpot with it, and the 

 other with water from a fmall adjacent river, three 

 times a week, for a month together, there being 

 litdc rain all that time. I obferved the efFeds care- 

 fully, and at the end of the month, the two fpots 

 were in the following (late: — That which had been 

 watered from the river was far better than the reft 

 of the field. The grafs was tolerably thick and high, 

 but weak and faint, fecming to have little virtue in- 

 it, and of a yellowifli green. But on the other fpot, 

 which had been watered with the pond-water, the 

 grafs was much thicker and higher; being as ftrong 

 and fucculcnt as any part of the firll crop had been, 

 of a deep healthy green, and near eighteen inches 

 high. I then determined to cut both, and keep 

 them feparatc, in order to afcertain the compara- 

 tive value of the hay. 1 did foi aiid when it waa 

 made, on weighing each, I found that on which 

 tlie pond-water had been ufed near double in quan-» 

 lity, and P[iuch luperior in qualjty, to ^he other.
