Conemaugh of eighteen miles, and aiiotlier from Lc 

 Boeuf to Presqu' isle of fifteen miles : every one 

 must rejoice, that this canal which was commenced 

 fourteen years since, and suspended, owing to a va-* 

 riety of causes, is now in a train of being completed; 

 it will be productive of incalculable advantages to 

 Pennsylvania, as it will pass through the most in- 

 habited and central parts of the state, and will open 

 such numerous sources and channels of inland trade 

 all leading to Philadelphia, as perhaps no other sea- 

 port can boast of : for the communication with the 

 immense territories connected with the Ohio and 

 Mississippi waters, and the lakes, is as easy, and 

 may be as cheap as to any other port on the iVtlan- 



Piscataqua Eiver» 



The Piscataqua is the only large river whose 

 whole course is in New Hampshire. Its he^id is a 

 pond in the north-east corner of the town of Wake- 

 field; and its general course thence to the sea is 

 south-south-east, about forty miles. It divides New 

 Hampshire from York county, in the district of 

 Maine, and is called Salmon Fall river, from its 

 head to the lower falls at Berwick; where it as- 

 sumes the name of Newichawannock, which it bears 

 till it meets with Cochecho river, which comes from 

 Dover, when both run together in one channel to 

 Hilton's point, where the western branch meets it. 

 From this junction to the sea, the river is so rapid 

 that it never freezes ; the distance is seven miles, 

 and the course generally from southr to south-east.
