Bridge, where tlie line between the Millstone Grit and Coal 

 Measures strikes the stream, the elevation is 350 feet. Yery 

 soon the county boundary leaves the Derwent and runs north- 

 ward along the Stanley Burn to the Tyne at Wylam. On the 

 north side of the Derwent the moor between Hedley and Chop- 

 well Park attains 850 feet, and between Eyton and "Winlaton a 

 small stream runs down a wooded dene to the Tyne at Blaydon. 

 Along the 10 miles due east, from Shotley by way of Medomsley 

 and Tanfield to Eavensworth, the highest points of the undulated 

 coal-country reach from 750 to 600 feet. The parks and halls of 

 Chopwell, Gibside, and Axwell pleasantly diversify the last 5 

 miles of the Derwent, which joins the Tyne a short distance 

 above ]N"ewcastle. The undulated coal-country south of E'ew- 

 castle is drained by a small stream called the Team, with a 

 wooded dene at Tanfield, and a castle and park upon its banks 

 at Eavensworth. A narrow tract of Magnesian Limestone be- 

 longs to this drainage district, the highest point of which is at 

 "West Boldon (307 feet), whence a rivulet runs down to the 

 Tyne at Jarrow. The area of the district is about 200 square 

 miles.

The county of Durham, towards its western extremity, does 

 not measure more than 10 miles across. The Derwent does not 

 attain the county boundary, and this 10 miles includes the whole 

 breadth of the tract drained by the "Wear and half of that drained 

 by the Tees, the other half belonging to Yorkshire. The "Wear 

 watershed forms the eastern boundary of Cumberland for 6 miles,
