 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 laminæ. 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. Buddle by the manager of the quarry, I refer to Mr. Buddle'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. Boring in the East part of Sprouston 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, neat the fort of the Flodden hills, a stratum of grey or greyish white arenaceous limestone bassets out.
