44 On the west side of Smith Bay opposite the south end of Trap Island there occurs on the cliff an exposure of shale nearly 30 yards long. The shale is dark bluish black but in the north part unusually slickersided as along the surfaces are glossy shiny black. The bedding appears to correlate with the slickensided surfaces and is nearly vertical striking N 40-25°E, and dipping 80-60° S.E to S. The shale is partly much torn and both the beds & they appear to be curl up gray gneissy phyllite as indicated. The sketch at this locality appears to just as a low angle and a fault along it suggests shale phyllite contact cutting parting up into the shale-trap contact as elsewhere dark ledges. About 10 yards to the north occurs a zone of phyllite tuff, stratified by a series crystalline intrusive appearing at an exposure 50 W in apparently the same formation as the strata above noted. The strike is N 2-5° E, dip east 37°. The tuff contains: complete fossilizations of calceolaries, namely: Parvula 6.52.3 B. Whitfieldella Cannav-tricula programmat? Bohennarella Lepiotaera (Actinopterella) (common nation) Actinopterella Leonard's Gastrod Lake Island in the lower bay between 6.43 & 6.52 is composed mainly of a phyllite layer of dark shaly black shale lying near to couple of places on the north side of the phyllite fragmented in a little core in the west it appears a trap dike a few feet wide in 1247° E, and also a gaitore which the trap another gallic shale about 35 feet appear in the east side of the north shore of the island and on the S.E. corner of the island. Specimen from former locality 1246. The two little islands N.W. of the middle of 6.43-8 are really but a single as separated only at high tide. Both as composed of phyllite 1248 in the east of the southern island occurs a trap, about 25 feet wide of shale striking N 87°W, dipping 32° E and containing Galleries 1247 The shales are of a gray gneiss beds B. S. Smith & Co. 45 On the south-west corner at 6.43: I examine which shows dark gray shale about 5 feet of which are exposed striking N 26°W and dipping 37°N E. Rocks examined including: Grammysia impulata common Myriophyllum commune Lepidolita Cannavella Midlewards rare Lingulae coris common This forms shows that the singularis fauna in the beginning out of the Jarnet Point shale Programmat. Ink shales shale varying 1 to 2 feet blue plate (dark gray flow) - zone bicrusted contact shrunken gaitore. Programmatic portion about a third of a mile south-west of Dans Court showing relation of Ferry, phyllite & gaitore. On Dans Point occurs about 25 feet of dark phyllite striking N 70°W and dipping 8°N, 35°. The shale nears phyllite intrusions and latest against the very crystallization of fault plane. This whole southern tongue is a rare Middle-period and appears similar to the gray shale on Moose Island over the Carleton Island RR Bridge. The fauna is 9.2 B totally for a couple feet the phyllites are stained purple but by three intruded phyllite tongues. See Figure 1 shales contain a few lingulae = 9.2.3 B² In a little cave on the west side of the center due west of Red Head occurs a patch of dark blue shale along the shore about 20-25 feet exposed. The shales are largely injected with calcite in places (perhaps all at the north largely cleaved, near this middle rift strike is N 60° (dip 35°SE) running around to N 30°E/dip 20° S.E) and at the west end also N 8° E. Dip 38° E The shales remain contain stains with gypsum phenocryst. Fossils are common: 6.52.3 A² The folies contains: Spirifer viscosus C " varicosi C " ?
