Firft\ " What kind of water have you found 

 moft efficacious?" &c. I anfwer, That which has 

 firft run a confiderable way as a brook or rivulet, 

 or rather as a large and rapid river. 



I formerly occupied fome water-meadow not 

 many miles diftant from this place, where there 

 is a great deal of land watered from the Kennet, 

 a very confiderable river which rifcs at a village 

 of that name not far from Marlborough. The 

 occupiers of thofe lands are uniformly of opinion, 

 that the more thick, turbid, and feculent, the 

 water is, the greater will he the benefit to be 

 derived from the ufe of it; and the opinion is 

 certainly well fupported both by reafon and ex- 

 perience. Hafty mowers, and very heavy rajns, 

 dilute the manure, and wafh away the fine pul- 

 verized earth from the adjacent lands for many 

 miles round; fo that as the waters increafe, and 

 become more rapid, they alfo become more re- 

 plete with fertilizing matter, as is vifible to the 

 eye by the quantity of fcum, mud, and fine earth, 

 remaining on the furface when the water is drawn 

 off. The benefit derived from flooding may in 

 general then be computed, ceteris paribus, from 

 the quantity of feculent matter depofited by the 

 water, for it is, I believe, invariably found to be 

 in proportion thereto.
