J. 3. 1 Banded grey slate like that of Racoorn Island, N84 E dip 80 S. Most prominent cleavage N65W, dip 72S. About 115 steps across the strike of slate, all parallel; J 3 2 Thinly cleared slate of dark purplish grey coln, in some respects like the slate in the R.R. cut at Waymouth. N84 E dip 80 S. This cleaved slate was apparently banded at one time; a little further north it is readily seen that the slate was banded, cut by a dyke N 45 west, width 3 feet. Thirty seven steps across the strike to bare exposure at top side, two dykes in the plane of the slate, 15' in clus, widths; evidently a faulted single dyke, A third dyke not in line north the next but also following its strike belongs to a different appa- rent. The exposure is a long one. K 3 1 The dark colored banded slate of J,3,2. N 82 E, dip vertical, many dykes intrusions parallel to bed, ding dip vertical a 85 S. Further east for a long stretch the strike is N 70E dip 85 S. The banded structure is also well exhibit ed still further E, strike N 63 E ?5S, K 3 2 Strike N 76 E dip 85 S. K 3 3 Strike N 85 E dip 85 S. K 3 4 Strike N 74 E dip 85 S, K 3 5 Strike N 72 E dip 65S Numerous dykes of whorish coln, transient to, both with the strike and cutting across the course occur on this isolated slate Island. K 4 1 A ledge above water at low tide only. The Cambrian red conglomerate and sand- stone clearly a sandstone, two purple color striata into almost absent, at other times pres- ent. Strike E+W. dips southward I think. L 4 1 The red Cambrian conglomerate but with lost the red coln. Strike E+W. dip, 45 S. At this particular locality bands of sandstone intervene in the conglomerate, especially towards the bottom. An E+W where dyke cuts across the strike dipping 45o to the North. L 4 2 Red Cambrian conglomerate with landstone intercalated. Strike E+W. dip 45 S. Sandstone bands present, alt.
