16 REMARKS ON THE VEGETABLE REMAINS 
teristic marks of the new red sandstone formation*. It is about 45 feet in 
height, and nearly 120 yards in length. It dips at an angle of 9°, in the 
direction of north 35 east. It is underlaid at its western point by a bed 
of shale, containing remains of vegetables, and dipping north 37 east, at 
an angle of 16°. 
On the south side of the river, at Twizell grounds, a similar sandstone 
is quarried. The position of this sandstone is altered near the bank, being 
bent down towards the river. It dips here 8° to the north-east, but in 
the western part of the quarry it appears to take a more regular course, 
and dips to the south at the rate of 8°. Further down the river, a bed of 
shale is seen abutting against this sandstone, evidently thrown up by a fault. 
This quarry possesses all the characters of the new red sandstone. There 
is also a bed of sandstone quarried in the burn side close to Milnegraden. 
It is of a grey colour, and close grained, affording a very fine building stone. 
It dips at an angle of 5° to the south south-east. 
Again, a few hundred yards to the north of Coldstream, is a thick bed 
of very fine sandstone, belonging to the mountain limestone group, dipping 
to the east south-east. In its lower part, vegetable remains, mineralized 
with sulphate of iron, are lying in horizontal position. It rests upon a bed 
of soft bituminous shale, of unknown thickness, and the beds of sandstone 
are streaked and irregularly marked with the same substance. 
Many persons having great doubts how far the coal-field, or moun- 
tain limestone group containing beds of coal, which is worked to the south 
of the river Tweed, extends in a northerly direction, Mr Forstrer and 
I proceeded from Coldstream to Greenlaw, between which places an ex- 
tended and undulating plain of diluvium evidently covers the bassets of 
many strata. On the top of the hill, south-east of Greenlaw, is a quarry 
of red sandstone. It dips to the south at an angle of 19°. This great 
* Since writing the above, bya close examination of the red sandstone of the county, 
I have strong reasons to believe, that these red rocks, so much resembling in mineralo- 
gical character the new red sandstone, are subordinate members of the mountain lime- 
stone group. An account of the red rocks of Berwickshire will be published in the next 
number of the Transactions of the Natural History Society of Newcastle-upon-Tyne.
