BETWEEN THE TYNE AND THE WANSBECK

The other three slacks are dry, or at most contain a small 

 "letch" in their lower parts, which carries away local drainage. 

 The first has its head at High Callerton, and cuts mainly 

 through rock as far as Black Callerton. The second takes-in 

 at Hold House and mouths at Low Luddick; the third is 

 roughly parallel to this at about half-a-mile distance, and ends 

 near the Wheat Sheaf Inn at Woolsington. The Ponteland 

 road runs for some little distance along this slack. The last 

 two seem to be cut almost entirely through drift. 



The survey of these slacks has yielded the following

Closely resembling these (differing in fact only in position) 

 is a slack resembling a broad moat, which isolates Darras 

 Hall from the Dinnington Ridge, and is roughly parallel to 

 it at some little distance from the top of it. The valley is 

 obviously independent of the Callerton Slack, for its outlet, 

 though near the intake of the latter, is at 325 feet, and there 

 are no indications of any direct connexion between the two. 

 We may call this the Darras Slack; its mode of formation 

 is clearly referable to the same causes which produced the 

 others. 



Just east of Newbiggin (near Westerhope), a short spur of 

 the Kenton Ridge which passes through Newbiggin and 

 Kenton Bank Top is breached by a deep cutting known as 

 Newbiggin Dene. This has all the characteristics of the 

 other slacks. It takes in at 300 feet, ceases to be a feature at 

 250 feet near Kenton Bank Foot; it is cut through rock, is 



* I am greatly beholden to Dr. P. C. Garrett for the accurate survey of the 

 Callerton, Luddick, Woolsington, and DaiTas Slacks ; the flgrures for the Heddon 

 Slack are approximations only.
