the Sow, Charnet, EccleshelUwater, and other streams, and then 

 runs to the eastward. It becomes navigable at Burton-upon-Trent, 

 where it leavos this county, and flowing through those of Derby, 

 Nottingham and Lincoln, discharges itself into the [lumber, that 

 great receptacle of the northern rivers, running a course of near two 

 hundred miles. It enters Nottinghamshire at the south-west point, 

 where it is joined by the Erwash, and passes to the eastward till 

 it reaches Newark, where it forms an island 5 when turning to the 

 north, after a track of about fourteen miles, it forms the boundary 

 of that county on the side of Lincolnshire. Poets have derived the 

 name of this river" from thirty kinds of fishes which arc found in it, 

 and from thirty streams which flow into it. 



The bounteous Trent, that in himself enseams 

 Both thirty sorts of fishes, and thirty sundry streams. 



But this ought only to be considered as a poetical fiction. Mr. 

 Pennant determines the name to be Saxon, and says it is derived 

 from its rising from three heads. The Dove which rises in the most 

 northern point of Staffordshire, forms the boundary between it and 

 Derbyshire, and joins the Trent a little below Burton. The Sow 

 rises a few miles to the west of Newcastle-under-Line, and falls into 

 the Trent on the south-east. These are well stocked with fishes, 

 especially the Trent. A canal has been formed from Chesterfield, 

 in Derbyshire, which, passing through the northern part of Notting- 

 hamshire, communicates with the Trent just below Gainsborough; 

 it was begun in 1773, and completed in 1775. In its course a sub- 

 terranean tunnel is cut through Norwood hill, which extends 2850 

 yards, or upwards of a mile and a half, so perfectly straight, that the 

 termination at one end may be seen at the other, The arch is 

 twelve feet high, nine feet three inches wide, and in the deepest 

 part thirty. six yards below the surface of the earth. By means of 

 the numerous canals which are now formed in the north of England, 

 Q communication is opened between the Trent and the Mersey, or 

 quite across the kingdom, from east to west. 



The rivers which fall into the HUMBER are the Ouse, or North- 

 ern Ouse, and those by which the Ouse itself is enriched, as the 

 Dun, or Don, the Derwent, the Calder, the Aire, the Wbarse, the 

 Nidd, the Yore, and the Swalt. The Ouse rises in the west-north-
