354 Remarks on Mr. Babbage's Work 



I am informed by a gentleman well acquainted with the neigh- 

 bourhood, that some years ago the yellow sand was worked 

 in a pit near to Harton Toll Bar, on the turnpike road from 

 South Shields to Sunderland. At the mouth of the above- 

 mentioned Deans, near a brewery, a sandstone of the'coal mea- 

 sures is visible, on the western side of the burn; rising to 

 the top of the hill, on the opposite side, we find the new red 

 sandstone, in Mr. Fox's Quarry, which has been extensively 

 worked for a building stone; it may be again seen in the Col- 

 liery Quarry, on the road side leading to Westoe. The mag- 

 nesian limestone, which forms the capping of the hill, being 

 also worked in an adjoining field. 



In a quarry at Lay Gate, near South Shields, the red sand- 

 stone forms the upper bed, and rests upon a white sandstone, 

 which is evidently, from its general characters, a coal grit, 

 having abundance of vegetable remains in it. This quarry 

 was the last point at which the red rock was observed south 

 of the Tyne ; but on the north side it occurs again, forming 

 the cliffs below the Spanish Battery. Here neither the lime- 

 stone nor the yellow sand appear, but on the other side of 

 Tynemouth Haven the limestone forms the uppermost bed in 

 the Castle Cliff, and at its lower part alternates with the yel- 

 low sand ; the latter is upwards of twenty feet thick, and is 

 seen resting upon the red sandstone, which forms the whole 

 of the lower part of the cliff on its south and eastern faces. 



A well-known basaltic dyke here cuts through the red 

 sandstone, and the yellow sand; but is not seen in contact with 

 the limestone. In the eastern face of the cliff, several faults 

 appear traversing and affecting alike the whole formation. 



At the base of the cliff, on the northern side, in Percy 

 Haven, a coal sandstone makes its appearance, rising rapidly 

 towards the north-west, being surmounted by the superior 

 formation ; both members of which may be traced all round 

 this haven, and extending to a point a little short of the Two- 

 Gun Battery, where they are cut out by the rising of the beds 

 of the coal formation.

Gentlemen, 

 TN looking over Mr. Babbage's late publication "On the 

 * Decline of Science in England," I regret much to see that 

 so able a man as he is, and one who has hitherto been distin-
