South "Wales ; it rises on the south side of Plinlim- 

 mon hill, on the borders of Montgomeryshire and 

 Cardiganshire, being rather to the south of the

 from Eadnorshire ; when past the Black Mountain it 

 flows eastward to Hereford, Eoss, and Monmouth ; 

 from whence it proceeds south till it unites itself 

 with the Severn below Chepstow, thus forming part

THE TRENT is a river which pervades some 

 of the most fertile districts in the kingdom ; it rises

 the sestuary of the Northern Ouse to form the 

 turbulent river Humber. 



THE HUMBER is formed by the Trent, the 

 Northern Ouse, the Derwent, and several other 

 smaller streams. By the late inland navigation it

 in the counties of Lincoln, Nottingham, York,
