tliofe which will produce Fruit on 

 Dwarfs, are much more likely to 

 do fo when train'd on an Efpalier, 

 where they can be much better 

 manag'd, and therefore I judge it 

 much the better Method, as being 

 more certain, and the Trees will 

 make a better Figure.

EARTH is the principal Mat- 

 ter whereof our Globe con- 

 lifts,- the Chara6ler of which, ac- 

 cording to Dr. BoerhanTje, is, That 

 it is a FoJJil Body, neither dijfoluble 

 hy lircy Water, nor Air j that it is 

 injipidy and tranfpare?^t j wore fufi- 

 ble than Stone ; fiill friable, and 

 containing ufually a Share of Fatnefs. 



There is no fuch thing as a 

 ftridly fmiple Earth ; Mr. Boyle 

 fays. That it does not appear, that 

 Nature any more than Art affords 

 an elementary Earth 5 at lea ft, lb me 

 which appear of the fimpleft Sorts 

 arc found, upon Examination, to 

 have Qualities not afcrib'd to pure 

 Earth. 



Of fuch Earths, fome are ftmple, 

 and immutable, as Chalk, Pumice, 

 aid rotten Stone j others compound 

 and fatty j of which kind are all 

 Boles, red, white and brown ; Ful- 

 lers Earth ; and divers Kinds of 

 Medicinal Earths, as the Cretica, 

 Hungarica, L^mnian Earth, and 

 others. 



Which Earths are all refolvable 

 into Oil, a little acid Salt, c^c. and 

 a Calx, which is the Bans, or the 

 Earth properly fo call'd. 



Sand is by Natural! fts generally 

 rank'd as a Species of Earth, tho' 

 not very properly. In that Saads, 



E A 



ftri£tly fpeaking, are a Sort oi 

 Cryftals, or little tranfparent Peb- 

 bles, and are calcinable, and by the 

 Addition of a fix'd Alcaline Salt, 

 fufible and convertible into Glafs. 



The fat Earth is render 'd fertile 

 by the Means of Sand, and be- 

 conies fit to feed and nourifli Ve- 

 getables, ^c. for pure Eatth is 

 liable to coalefce into a hard cohe- 

 rent Mafs, as in Clay ; and Eartf^ 

 thus imbodied, and as it were glu'd 

 together, w^ould be very unfit for 

 the Nouriftimcnt of Plants. 



But if hard Sand, i. e. Cryftals, 

 which are indiiroluble in Water, 

 and ftill retain the fame Figure, be 

 intermixed with fuch Earth, they 

 will keep the Pores of the Earth 

 open, and the Earth it felf loofe 

 and incompa6t, and by that means 

 give Room for the Juices to move, 

 afcend, &c. and for Plants to be 

 nourilh'd thereby. 



Thus a Vegetable being planted 

 either in the Sand alone, or in the 

 fat Glebe and Earth alone, receives 

 no Growth or Increment, but is 

 either ftarv'd or fuffocated ; but 

 mix the two, and the Mafs becomes 

 fertile. 



In effeft, by means of Sand the 

 Earth is render'd, in fome meafure, 

 Organical, Pores and Interftices be- 

 ing hereby maintain'd or preferv'd, 

 fomething analagous to Veflels is 

 effeded ; by which the Juices of 

 the Earth may be convey'd, pre- 

 par'd, digefted, circulated, and at' 

 length cxcern'd and thrown off iiv 

 the Roots ot Plants. 



The Earth is made up of two 

 Parts : The firft the containing 

 Part, i.e. the Body, Bed or Couch j 

 the fecond Part contained, and thofe 

 are the nitrous or fulphureous Par- 

 ticles or prolifick Sahs. The firft 

 is a lifelels inanimate Mafs, and is 

 only the Receptacle of the other :
