Kroll - Tarfalin (continued). If then creamy, often coarse or slightly clayey ss, sometimes more fine but never once cemented, usually crumbling readily, the result is great slumping in cliffs along shore and seawines. They are easily susceptible to the influence of tides. Course mere clay or smutty flints interlarded in course drosses or black once a loosely carbonaceous sh. All are thin and could seem to constitute but poor fuel. Ordinarily would not be called coal. Fifty tons mined an- nually for use at Omenad. There's little regularity in terms lenses of ss, of flits, sh, interfere with regularity. Clays often a few inches apart, sometimes separated by white or creamy sand. In general they appear to be in two groups, (a) within 200' at the tide or the exposures of grain at tide. (b) about 400'-500' A-T. (c) about 800'. The details of stratigraphy vary too much to make detailed sections of value to find on considerable distances. In general the dips 5°-15° towards the coast (N), steepens near the shore and flattening somewhat locally further up the seawine. A slight westerly dip is seen along the cliff tops and it's apparent for local. At a point about 10m E. of Tarfalain (photod) the cret. is seen to lie along shore horizontally against a hill- roll of reddish granite or grain, thus [illegible]
