AND it is from thefe Supplies of Moifture, that deep Soils fupport 
their Plants in very dry Seafons, when thofe on fhallow dry-bottom’d ° 
Lands perifh : For tho’ the Moifture of thefe deep Stratas is not fit for 
the Nourifhment of Plants, when fo very deep, yet as it afcends and 
comes nearer to the Surface, ‘tis better prepared, and at length made fit 
for their Reception. 
THE Moifture contain’d in the lower Strata’s, is, in fome mealure, 
tais'd by the attractive Power of the Sun, as well as by the imbibing 
Force of Vegetables ; which laft is undoubtedly much ftronger than 
the firft, becaufe thofe Countries which greatly abound with Woods, 
have greater Rains than thofe that are unplanted : For the Roots of 
Trees having a very great imbibing Force, do draw up and imbibe 
great Quantities of Moifture, which they are continually perfpiring away 
at their Leaves, and thereby furnifh the Atmofphere with great Quan- 
tities of Water, which unplanted Lands cannot do. | 
"TIS obfervable that Rains will freely penetrate the Earth Two Feet 
deep, but feldom freely deeper, therefore at that Depth there is contain’d 
not only the Rain Water, but the Spring Water alfo, in fuch Quantity 
as ‘tis raifed by the Two attractive Powers aforefaid: Which Depth Na- 
ture feems Wiftty-to—hevechafen, not only that the genial Heat of the 
Sun can there prepare the crude rancid fit for the Nourifhment 
of Vegetables, but the fcorching Rays of the Sun, and drying Winds, 
cannot prefently exhale away the neceflary Moifture, fo as to deprive Plants 
of their Support. ; 
IF any doubt the Afcenfion of Moifture, let them read Mt. Hales’s 
Vegetable Staticks, Pag. 54: and 55. _ Having thus explain’d the Man-- 
ner of Nature’s fupplying Plants with Moifture in hor and dry Seafons, 
from the loweft Strata’s of the Earth; perhaps it mayn't be amifs if I 
fhould fpeak a Word or two, in relation to Dews, which are very re- © 
frefhing to Plants in dry and hot Seafons. 
BY an Experiment made Auguft 15. by Mr. Hales (vide his Staticks, 
Pag. 53.) it appears, that two glazed Earthen Pans, which were three 
Inches deep, and twelve Inches Diameter in Surface, fill’d with pretty
