Show The V.egetation ~~Book IIL fine a Staple, as Flax (for all ourfine Hollands are made of Flax) yet Flax, which is but of the fame finenefs as Hemp, will never, byall the Art yet known, be made fo white as Hempis made. The Qualities therefore of the beft Tor, that can be in Nature, are that the Staple be Jong, fuall, tough, and white. So that if in the Bargue of any Plant, we can find thefe Qualities, or any of them, to excell; we may be fure, it will be of better ufe, in fome refpetts, for the making of Cloath, or other purpofe, than Fax it felf. 14. §, I WILL conclude with one Ins#axce more, and that is as to Grafting. The good and happyfuccefs whereof, doth certainly depend uponthefuitablenefs or refpondence betwixt the feveral Parts of the Stock and Cyon; asthe Bargue, Wood, and Pith; and that both as to the Number, Size, and Pofition of the faid Parts,and.of their feve- ral Pores or Veffels : according to the degrees whereof, the Conjunéfion ( ceteris paribus) will be more or lefs profperous. So that of all fuch Conjundions as are found to be apt and taking, and which fome have learned not without long Practice and Experience; another, only by comparing the Branches of Trees together, may withlittle trouble, and in much lefstime, inform himfelf. By the fame means, fome Conjundions which feem to be ftrange, as Quince and Pear, White Thorn LEAVES, FLOWERS, FR UIT S ad°S BE DS and Medlar, &c. do yet, by the refpondence oftheir Parts, as well as by Experience, appear to be good. Andthere is no doubt, but that a ine! many Conjundions not yet tryed, or not known to have been fo, may upon the fame ground, be tryed with good fuccefs, 15. §. The chief Ufe of Grafting and Inoculation, is, That they Accelerate the growth of Good Fruit. The Caufe whereof, isthe Kvot, which is always made in the Conjunéfion. By means of which, all the Sap is ftrained, and fo afcendeth up into the Graff or Bud, both Purer and in lefs Quantity, and istherefore better and fooner concoéted, Hence, the fmaller the Frait of any Tree, thoughit be notthe beft, yet the Sap being there, in le/s Qantity, is the fooner ripe. On the contrary, where the Swp afcendeth too freely, it doth not only retard the growth of the Fruit, but produceth Barrennefs; as is feen in thofe luxuriant Branches, where it runs all up to Leaves. Hence alfo Vines, In Four Parts. i The FOURTH BOOK. by Bleeding, become more Fruitful: that is, by the Effufion of Par? of the Sap, there is a more eafier elioration of that which remains, Even as Phlebotomy doth oftentimes produce a more healthful and better Habit of our own Bodies. To conclude, the leffening the Quan- tity, and thereby the melioriation of the afcending sap, by Kuots, is Natures own contrivance; as is feen in Sugar-Cane, Corn, and other Plants.
