 common workman. 



Application. Marie requires no preparation. It is best applied on 

 /eys : and the longer it lies on them before it is ploughed 

 in, the better. It should not be ploughed in too deep. The 

 best way therefore is, to plough the ley shallow for pease. 

 To turnips there ib but one objection, the giving so much 

 tillage so early utter the improvement. Potatoes are mis- 

 chievous for the rirst crop after land has bteu marled. Next 

 to leys, fallows are the best to receive marie. When the 



SooMtk farmer has a choice, on wet and heavy soils it should be 



summer vyork, and on dry ones it may be winter. 



Qaatitj, The quantity employed is of great importance. From 120 



to. 150 cubical yards per acre being laid on a poor sand, the 

 productiveness of the land has been injured for twenty years. 

 Half this quantity would have done good. It is better to. 

 marie twice, than apply too much at once. On poor, loose, 

 wet loams more may be used than on loose sands. On loose 

 peat bogs, and on moors, the greater the quantity the 

 greater the improvement. Where the object is to give cal- 

 careous earth, the quantity should be small, as from ten to 

 twenty tuns. 



Soi} requiring The defect of a soil must be understood, before a wise 

 farmer will put himself to the expense of marling. Every 

 day's experience will inform him, whether his land want 

 tenacity and consolidation ; but the want of an addition of 

 calcareous earth as a food of plants can be discovered only 

 by analysis. Other circumstances deserve attention. If 

 the chrysanthemum segeturp, corn marigold, rumex aceto- 

 sella, sheep's sorrel, or polygonum pennsylvanicum, abound, 

 the experienced farmer will pronounce, that the land wants 

 marling. Turnips producing deformed strings of roots, 

 without swelling into the proper globular form ; or being 

 subject to the well known distemper of the anbury ; both 

 afford a proof of too much looseness of texture, and sug- 

 gest consolidation by clay tnarle, after which these evils 

 vanish. The erica vulgaris, common heath, or ling, is ge? 

 »l\y a proof of an acid soil ; a&d all peat soils are found 



»aile.
