Watermenj arecaufed by the coming down of the Land- waters 
after a very great rain, which being encountred by the Tyde of 
the flood from the mouth of the Thames^ cannot but fwell to an 
unufual height : To induce us to believe which, we need only 
confider, thafthe latter end oBoberj and beginning of Novem- 
ber (or rather both thoft whole Months ) are generally the raini- 
eft part of the whole year. Now if the great rains fall fb, that 
the Land- waters come down to the flowing part of thQlhames, 
ju^uiponiht Full ox change^ when the Spring-Tydes happen 5 as 
they did (for example) 6*e/?/e^i. 30. 1555, ^ndOQober 27. 1629« 
(<y/f?n?and^^^/aren)y Authors3)tho(e Spring-Ty des muft be the 
bigheryas proceeding from a double caufe. But^ 
5* (To fay no more of the Jhames.^ but toconfider that and 
other great Rivers jointly with the Sea'^) there is another thing 
notorioufly known by all Seamen to be a caufe of High or Low 
Tydesj which I cannot but fay, th:5t 1 wondefj the Author hath 
taken lb little or no notice of in his Eflay 5 namely the fitting of 
the Winddii fuch or fijch a point of compals 5 and blpwing hard. 
It is the conftant faying of all Sea^men in Kent:^ that ever I met 
withj that the North' weft-wind makes the higheft Tydes in the 
7hames^ Medvpay 5 and all the coafts about the 6*^///^ and North- 
forelands ; and likewife on the coaft o( Holland and Flanders, 
And the reafcn they alledge for it. i!»^ beeaule ( fay they ) thai 
wind doth with equal force blow io/th at both 
endsof this liland of ^r;V^7>j that is, from the North- ward be- 
tween the Coafts of Scotland^ Norway i Jnttaf^d and ahb 
from the Weft- ward by the Coafts of Cornwail^ Devotijhhey Dor* 
fefjljire <y%^c. up a long the «S^/eifz/e^ and for the fame reafoo they 
lay (and I think truly) that a South-Eaft wind deads and hinders 
the Tydes in the place before mentioned near the f orelands. And 
agreeably to this, ( if the teftimony of Youth may be admitted ) 
I very well remember when I was a boy, and lived at home with 
my FsLihcv ^t RocheJler, which is near enough to Chatham, to ob- 
ferve, how the Tydes run there, that !when the Tydes were un- 
ufually High, the Wind was always North- weft, and the Moon 
near the Full, or Change. And fo confident I am of my memory 
in this pointjthat if enquiry be made about Chaiham^lh^ Hundred 
©f Hoo^ and the Ifle of Graine, I believe the Inhabitants will with 
©ne voy.ce fay , that they never fear their Low Marfhes beiag 
overflowed
