EXPLANATION OF THE PHOTOGRAPHS. 



i. The Blanch Burn Kaims. This kaim-ridge is cut at the 

 north end by the Blanch Burn and at the south end by 

 the Newbiggin Burn. The former section is shown on 

 the left of the photograph, also the outline of the ridge, 

 but not its delicate meanders. 



2. Cemented glacial gravels on the Wansbeck at Mitford. 



The base of the gravels with immense boulders resting 

 on the clay is seen at the bottom of the photograph. 



3. Selby's Cove (B 7) near the intake, with Simonside in the 



background. This dry cleugh cuts across the ridge 

 between the Ousen and Cove Sikes. 



4. The swire at Humbleton Heugh near Wooler(C 12) — a deep 



dry valley severing a spur of the Cheviot Hills. 



5. Fawdon Dene (E 2) near Ingram, looking north. 



6. The lower marginal trench on Harden Hill (E 12) looking 



east, showing the steep rocky hillocks along its course. 

 In the middle distance, on the other side of the 

 Spartley Burn, is seen the rounded top of Castle Hill, 

 and close by in the adjoining wood is the dry channel 

 E 6, in alignment with the one shown in the photo- 

 graph. 



7. Harden Hill from the north. The marginal trench E 10 



on the south side of the hill cuts across the ridge, 

 notching the sky-line and tumbling abruptly down the 

 north side of the hill. The photograph shows the 

 notch and the steep portion of the slack. 



8. Erratic of fine-grained, reddish sandstone, resting on 



coarse-grained white sandstone. Harehope Burn, 

 near Blauweary, height 700 feet.
