But that which it does bear up, is mainly of 

 that light kind of Vegetable Matter ; and that 

 too perfectly diflolved, and reduced to fingle 

 Corpufcles, all fit to enter the Tubules and 

 Vcflels of Plants: On which Account 'tis, 

 that this Water is fo very fertile and pro- 

 lihck. 



The Reafon, why in this Propofition, I fay, 

 only a great part of the Terreftrial Mat- 

 ter that is mix'd with the Water, afcends up 

 with it into the Plant, is, becaufe all of it 

 cannot. The Mineral Matter is a great deal 

 of it, not only grofs and ponderous, but fca-

 Clods or MolecuU ; fuch as thofe mention'd 

 in H, K, and L, flicking to the Extremities 

 of the Roots of thofe Plants. Others of them 

 intangle in a loofer manner ; and form the 

 'Nubecula, and green Bodies, fo commonly ob-

 conjoin d, are too big to enter the Pores, or 

 afcend up the Veffels of Plants, which iingly 

 they might have done. They who are con- 

 verfant in Agriculture, will eafily fubfcribe to 

 this. They are well aware that, be their Earth 

 never fo rich, fo good, and fo fit for the 

 production of Corn or other Vegetables, lit- 

 tle will come of it, unfefi the Parts of it be 

 feparated and loofe. 5 Tis on this Account 

 they beftow the Pains they do in Culture 

 of it, in Digging, Plowing, Harrowing, and 

 Breaking of the Clodded Lumps of Earth,
