    caufe moft of the Artificial Pores (or Interftices) are too large, and then it partakes of the Inconvenicn= cles of the hollow Land untill’d. | For when the light Land is plow’d but once, that is not fufficient to diminifh tts natural Hollownefs (or Pores) and for want of more Tillage, the parts into which ’tis Divided, by that once, (or perhaps twice) plowing, remain too large, and confequently the artificial pores are large alfo, and in that re- {pect, are like the ill Till’d ftrong Land. Light Land having naturally lefs Internal Super- ficies, feems to require the more Tillage, (1) or Dung to enrich it; as when the poor, hollow, thin Downs have their upper part, (which is the beft) Burnt, whereby all (except a Caput Mortuum, or (1) As for Puffy Land, which naturally fwellsup, inftead of fubfiding, tho’ its Hollownefs is much abated by Tillage, yet is thought lictle better than Barren Land, and unprofitable for Cern. But what we ufually call Light Land, is only eompa- ratively fo, in refpect of that which is heavier, and {ftronger. And this fort of Light Land becomes much lighter by being ill Till’d; the unbroken piecesof Turf underneath undiffolved, forming large Cavities, encreafe its Hollownefs, and confe- quently its Lightnefs: I have often known this fort of Land defpis'd by its Owners, who fear’d to give it due Tillage, which they thought would make it fo light, that the Wind would blow itaway ; but whenever fuch has been thoroughly Till’d, it never fail’d to become much ftronger than before; and con- fidering that tis Till’d with lefs Expence, than very ftrong Land, it is, for feveral forts of Corn, found to be more profi- table, than Land of greater Strength, and Richnefs, that is more difficult to be Till’d. And [amapt to think, that this fort of Light Land, acquires more Cement by having its External Superficies often chang- ed, and expofed to the Dews, and other Benefits of the Atmo- {phere, as well as by the Increafe of (its Internal Superificies, which is the Surfaces of all the Divided Parts of Earth or) the Pafture of Plants; the one being augmented by the other ;/.e. That into the more Parts the Earth is broken, the more Ce- ment will it attain, from the Sulphur, which is brought by the Dews. . I Terra
