During tht laid Stor o, and aboot 8 a Clock in the

that I had iseverfeen the juick filver fo low ^ bur half an

Wiis not at all abated, at leaft to any appearance^ from 
whence I concluded, and faid it to thofe that wereabout

There are fomethat affirm, that the fcattering of this 
Salt water by the Storm will do a great deal of harm to 
the Fruits of the Earth 5 but for my parti am of a quite 
different opinion, for I believe that a little Salt fpread 
over the furface of the Earth, efpecially where it is heavy 
Clay-ground, does render it exceeding Fruitful v and fo it 
would be if the Sand out of the Sea were made ufe of to 
the fame purpofe.
