we dig, we find excellent white and yellow marie, 

 or clay. The g iodnefs of the marie is determined 

 by its fubfiding quick in water. On the firft dif- 

 covery of marie, our farmers fpread it in larger 

 quantities than at prefent j few laid on lefs than 

 eighty loads per acre ; but for near thirty years 

 pad, the general quantity has been from forty to 

 fifty loads (or tons) per acre. The efFedls of this 

 quantity will laft twenty years; and then half as 

 much more added will reftore fertility to the foil. 

 We have however found, that, on lands wholly 

 fandy, clay has had a better effed than marie j but 

 where the foil is a mixture of fand and loam, or 

 of fand and gravel, marie does excellendy. It is 

 not, however, to marie and clay only, that our 

 improvements are owing. Our fheep are folded 

 both fummer and winter. We fatten beads during 

 the winter on turnips in our farm-yards, in which 

 we alfo keep a large (lock of fwine. Our ftubbles 

 are cut, and, with large quantities of draw, con- 

 verted into manure. Oil cake is alfo laid on wheat 

 lands to the amount of two guineas per acre.— 

 Thefe manures, freely ufed, have proved the fources 

 of wealth to thoufands.
