^dgeSlS, Mr.YouKft says, "It is a 

 ** common practice in Lombardy to have 

 ** a sort of heavy harrow drawn along the 

 ** bottom of the main-carriers, in order 

 ** to disturb the mud, in autumnal, winter^ 

 ** and early spring irrigation ; and it has 

 ** been pmctised in England to throw 

 ** lime in, the great divisibility of which 

 " body in water is well known. These 

 *" are means of adding to the manuring 

 *' quality of the water very easily to be 



practised." 



re 



^his paragraph, however late or re* 

 luctantly introduced, is, in my opinion, 

 of more value than the whole dissertation 

 that precedes it; and indeed it renders 

 nugatory, or rather overturns, every an- 

 tecedent position which Mr. Young has 

 given us in his Calendar on the subject of 

 irrigation.
