for trade. It is one of the greater! rivers in 

 the world : is three Rnglifh 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 lets than five or 

 fix fathom. The greateft mips therefore 

 can fail quite up to the town and anchor in 

 good ground in five fathoms of water, on 

 the tide of the bridge. The water here has 

 no longer a faltifh tafte, and therefore all 

 deftru&ive worms, which have fattened 

 themfeives to the mips in the lea, and have 

 pierced holes into them, either die, or drop 

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

 The only difad vantage which trade la- 

 bours 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 Bojlon, New Tork, and other 

 towns which are nearer the fea. 



• The tide comes up to Philadelphia, and 

 even goes thirty miles higher, to Trenton. 

 The difference between high and low water 

 is eight feet at Philadelphia.
