A NEW PIOHA OP 



sweep of fir plantation stretches from Dilston eastward, and 

 further hack, hetween Slealey and the Derwent, is a hank of 

 heathery moor within 5 miles of the Tyne, which extends east- 

 ward as far as Shotley and Minster-acres House, with an eleva- 

 tion of from 900 to 1000 feet. The Derwent forms the boundary 

 of the district for 15 miles on the south, but its upper branches 

 on the ^Northumbrian side are very inconsiderable. At Allans- 

 ford Bridge it is 400 feet in altitude, and at Shotley Bridge 50 

 feet lower. Two pleasant wooded denes stretch down from the 

 moor to the Tyne at Biding Mills and Bywell. North of the 

 Tyne there is a gradually- sloping bank, cultivated and in some 

 places wooded, which attains 490 feet above Corbridge, 520 feet 

 at Heddon, and 400 feet opposite Newcastle. The principal 

 wooded denes of the north side of the river are Whittle Dene 

 near Ovingham, "Walbottle Dene near Newburn, Scotswood 

 Dene above Scotswood, and Heaton Dene below Newcastle, 

 none of them more than about 2 miles in length, and the latter 

 especially, like the last 15 miles of the Tyne, with but little of 

 the indigenous vegetation still lingering. The collieries are 

 principally concentrated in the area between JSTewburn, Blyth, 

 and Shields. There are two small streams between the Tyne 

 and "Wansbeck, which are called the Pont and Blyth, the former 

 of which is connected with Prestwick Carr, a large morass in 

 the low country 4 miles north of Newcastle, which was once 

 a good botanical locality, but is now enclosed and almost de- 

 stroyed by drainage. Except about Whitley and Tynemouth 

 this part of the coast is low and sandy, but in some of the 

 wooded denes of the interior several of the Montane plants are 

 scattered.
