( M3? ) 
Philcfophy will not, Ibeiieve, be much improv’d by this 
Miffion. This Gentleman told me. That the common 
Salt there made ufe of by the Dutch , was left in hollow 
Places of the Earth’s Surface, after the Sun had evapora- 
ted the Rain Water ; the matter of faft to me feems hard- 
ly credible : But if it be fo, I think it can hardly proceed 
from any other Caufe than the Rains diffolving a' Salt 
contain’d in the Earth, which, upon the Rains being eva- 
porated, remains in the Bottom $ which is the more pro- 
bable, becaufe that within five Leagues of the Fort is the 
Salt Bay, which has its Name from the vaft quantity of 
Salt dig g’d near it.
