Article XVIII. 

 Of River JFeeds as a Manure.

 Gentlemen^ 

 TN my communication to you, inferted in your 

 ^ fourth volume, concerning the extradion of 

 river weeds with their roots, but more particularly 

 of the river conferva, as a manure, I propofed to 

 give you a recital of farther experiments then be- 

 gun, but of which the refult was uncertain. 



In the courfe of my addrefs I had fpoken with 

 a degree of confidence of the expedled fuccefs of 

 a barley crop, in fucceffion to the turnips, of which 

 I gave you an account. I have now to add, that 

 my confidence had not betrayed me into a miftaken 

 eftimation of this new manure, as on lefs than one 

 acre and three roods, I had off feventy-feven Win- 

 chefter bufhels of malting barley, befides three 

 bufhels of a lighter quality. The quantity of this 

 produce may be afcribed to the general well ma- 

 nuring for turnips with common dung; but on 

 thofe fpaces wher.e none of that extended, a larger 

 produce was apparent; and even on the word part 

 of a field dibbled with wheat, and where, from its 

 quite oppofite quality to a gravelly height on which.
