90 Mr. N. J. Winch on the Geology of 



of the Lead-mine district, that I have given the account of them 

 under a separate section. This part of the country has been ex- 

 plored for coal by Mr. Buddie, and it is chiefly from his pamphlet 

 that I have derived the following information. 



In the vicinity of Wark, 15 miles south-west of Tweedmouth, 

 the beds consist of marl, micaceous sandstone, and slate-clay ; and 

 about a quarter of a mile below Coldstream, in the north bank of 

 the river, the strata are 



1. Soil, light and sandy ----- feet 15 



2. Ditto, gravelly -------- 15 



3. Coarse grained yellowish white micaceous 



sandstone --------- 18 



4. Micaceous sandstone alternating with slate clay to 



the level of the Tweed. 

 These measures dip to the east at an angle of 5 or 6 degrees. 



At Lenel quarry, half a mile below Coldstream on the northern 

 bank of the Tweed, the strata are, 



1. Light soil -------- feet 15 



2. Soft sandstone and marl ----- 4 



3. Sandstone resembling that in the last section 24 



4. Slate clay. 



At Bingham or Spring-Hill, north of the Tweed, the following 

 is the order of the strata. 



1. Light sandy soil. 



2. Blue marl inclining to a greenish colour. 



3. Blue limestone. 



4. Marl of slaty texture. 



5. Limestone. 



6. Slate clay.
