Mr. Hutton on the Stratiform Basalt. 



207 



between Sewing Shields Crags and the descent to the North Tyne, the 

 surface of the Basalt is laid bare for a considerable distance by the de- 

 nudation of the beds above it, and from the Basaltic plain thus exhi- 

 bited may be seen several small, round, isolated hillocks, of the same 

 substance, rising up. In several situations where the Basalt is exposed, 

 together with the beds reposing upon it, these sudden thickenings may 

 be observed, as in Hutton Hole Burn running from Hartside, about one 

 mile to the south of the road from Alston to Penrith ; in Black Burn, 

 where they occur three times, and at Holy Island.
