colour. These become more frequent in descending & then great mass of dark coloured amygdaloidal trap. No doubt contemporaneous (No. 6) Say about 100' thick.

Below this great thickness of yellowish weathering limestone in flaggy layers, but sometimes rather massive. Estimated at about 300' at least. Below this a series of variagated sandstones & slates. Sandstones red & greenish, slates generally grey or green. Many bands of white quartzite of small thickness.

There is no marked unconformity between the variagated beds below the limestone & that rock but they are beautifully pleated? or undulated on a small scale & appear to be more metamorphosed than those above them.

Found a rock surface green slate showing very well preserved glacial markings. The first seen in the mountains. Direction S.40"W or directly down the valleyís main direction. Great terraces of gravel remain on some of flanks of mountain. & streams in some places cut through genuine tough boulder clay of light fawn colour.
