for trade. It is one of the greateft rivers irt 

 the world : is three Englijh miles broad at 

 its mouth, two miles at the town of Wil- 

 mington, and three quarters of a mile at 

 Philadelphia. This city lies within ninety 

 or an hundred Englijh miles from the fea, 

 or from the place where the river Delaware 

 difcharges itfelf into the bay of that name. 

 Yet its depth is hardly ever lefs than five or 

 fix fathom. The greateft fhips therefore 

 can fail quite up to the town and anchor in 

 good ground in five fathoms of water, on 

 the fide of the bridge. The water here has 

 no longer a faltifh tafte, and therefore all 

 deftrudive worms, which have faftened 

 themfelves to the fliips in the fea, and have 

 pierced holes into them, either die, or drop 

 oif, after the fhip has been here for a while. , 



The only difadvantage which trade la- I 

 hours under here, is the freezing of the ri- 

 ver -almoft every winter for a month or 

 more. For during that time the navigati- \ 

 on is entirely flopped. But this does not ' 

 happen at Bofiouy New Torky and other . 

 towns which are nearer the fea. 



The tide comes up to Philadelphia^ and 

 even goes thirty miles higher, to Tretiton. 

 The difference between high and low water 

 is eight feet at Philadelphia.
