JUNE. 381 



In some countries it is the common manure; 

 and almost every where to be found when dug for ; 

 in such places, the farmers have nothing to do but 

 to resolve on the undertaking : they all acknow- 

 ledge the expediency of the work, and seldom dis- 

 pute the great profit of it ; but, in other parts, the 

 knowledge of marl is very confined. It may, per- 

 haps, be discovered half a century before it comes 

 into general use. In tracts of waste land, or sheep- 

 walks and warrens, lett at a shilling, or two shillings 

 and sixpence an acre, marl being discovered, and 

 rendering such land capable of yielding noble crops 

 of turnips, clover, and all sorts of grain and 

 pulse ; the uncommon effect, and the amazing ad- 

 vantages made by it are so striking, that the use 

 spreads fast. But, on the contrary, when marl 

 is found under richer soils (enclosed countries, for 

 instance, of ten or twelve shillings an acre), the 

 case is different: it will not make such an improve- 

 ment as on the poorer lands; and, as great for- 

 tunes are not suddenly made by the use of it, the 

 farmers in some districts will not be persuaded to 

 use it with any spirit, possibly, not at all : they think 

 that a rent, comparatively higher than the other 

 tracts, will not allow of their spending such sums 

 about it: that they will not reap equal profit is un-

 advantage ? Should they reject it, because they 

 cannot command fifty ? If tenants are backward 

 in making use of marl on lands of ten or twelve 

 shillings an acre, their landlords should set them
