 travellers observe, that the bed of this river, naviga- 

 ble so far on a calcareous bottom, becomes impassa- 

 ble in consequence of the rocks and sandstone of 

 Blue ridge. In Pennsylvania this ridge, less conti- 

 nuous and of inferior elevation, assumes in differ- 

 ent districts the various names of Trent, Flying,. 

 and Oley hills; but it is nevertheless the same 

 branch, which crosses the Schuylkill below Read- 

 ing, the Delaware below its western branch and' 

 the town of Easton, and proceeds to lose itself in 

 the Kaats Kill group towards the banks of Hudson's 

 river. 



The second chain, called North mountain with as 

 little reason as the preceding is named South, 

 branches off likewise from the grand arch of the. 

 Alleghanies, and running parallel with Blue ridge, 

 but west of it, crosses the upper branches of James^ 

 river twelve or fourteen miles above their junction, 

 and the Potowmac four and twenty miles above the 

 Shenando ; but when it reaches the west branches: 

 of Conegocheague creek, it divides into several i^a-- 

 mifications, which render its remaining part doubt-

 chain, though divergent, as its continuation ; which, 

 after having crossed the river Juniata, loses itself in 

 the rocky and marshy deserts north-east of the 

 Susquehannah. Others follow North mountain ia 

 the chain of Kittatinny, which, continuing in a more 

 direct line, runs parallel with Blue ridge as far 

 as the Delaware, which it passes above its west 

 branch and the town of Nazareth, then proceed- 

 ing along the east bank of that river, and termi-.
