Mr. N. J. Winch on the Geology of 



broad, and cropping out on every side. It is of a blueish white 

 colour, ' and close texture, well calculated for building, the best 

 part being about 20 feet thick ; but it contains in some parts nodules 

 of a black argillaceous earth scattered through it. It is in some parts 

 soft and slaty, with coaly matter interposed between the laminae. 

 Near the bottom of the quarry large irregular masses of very hard 

 calcareous sandstone occur. Three veins pass through this quarry 

 in a north and south direction. For the particulars respecting a 

 vein of coal given to Mr. Buddie by the manager of the quarry, I 

 refer to Mr. Buddie's pamphlet. 



This sandstone seems to belong to a detached mass of rock, which 

 reposes on the same kind of strata as are found in Mellendean burn ; 

 and this opinion is confirmed by the following section of a boring 

 lately made in the eastern side of the quarry.

The quarry of Stodridge situated in the Roxburgh estate of Fleurs, 

 is very similar to that of Sprouston. 



In, the vicinity of ford castle, near the fort of the Flodden hills, 

 a stratum of grey or greyish white arenaceous limestone bassets out.
