Monday, June 17, 1906. The beds from Kendall Head to the Little W. in More Island are composed of numerous over-crops of a very fine-grained, light gray- colored sand rock and has no glass, but has the appearance of an old volcanic on account of the absence of bedding planes, the Caroline 1871 gray colors in places causes this rock is distinctly bedded during the appearances of more or less lake shale, or of scales composed of volcanic matter. These stratified portions also contain fossils and are auto-stratified with volcanic ash beds. The fossils found are only Lingulas which are rather scarce. A very peculiar feature is that the strat. fish beds, if followed for a greater or slantwise distance, appear to bend into immense unstratified beds. Some dark strata appears along the southern shore of Kendall Head or northwest shore of Johnson Cove. A few fossils exclusively Lingulae were collected here = 3.55./a. The next locality is about 14.2 millimetre (miles map) below the western boundary of the Little square. Higher up, southerly of and about 20 feet below the top of Kendall Head, occur some more fossiliferous strata containing a few Lingulae = 3.55./b. About 4 or 5 p.m. Down down the hillside to the southwest occur some ash beds of which 3 land specimens were collected = 1033 Some more ash beds occur on the northwest corner of 3.54. C about the 80 foot contour just north of the fence corners from this fence corner extending southerly as far as [illegible] and including the first "O" in More Island there occurs a series of ladder fossil. Layers of dark rock containing a few Lingulae = 3.54.6.a. These one fluid structure, light gray in color, epidote by igneous (1039 no foot found quantity) about 20 feet up the hill, the strata are very much contorted and near the top of the rock at all of the southwest corner of 3.57.D a series of readings in this place gave STRIKE DIP A 5.70°W 84°, N.20°W B 3.54.W 62°, N.35°W C 4.45.W 53°, N.45°W STRIKE DIP D 5.70°W 40°, N.20°W E 3.72.W 45°, N.20°W F 3.55.W 60°, N.35°W In a as at the top of the hill, includes some finely stratulated beds in which are rolled up large angular bedded stratulate fragments. The general dip of the slant beds is very heavy 50 or 60° and more the general axis of the beds in 3.70°W. These bodies cut by a similar lightish dike which contains a great deal rock fragment as well as dark scale (1038) a few tiny white spots near the side of the rock below the first house. CARRYING PLACE COVE WESTWARD A patch of ashly quartziferous beds outcrops on the shore in the western side of 3.54.C at the eastern edge of 3.54.F. The beds of this outcrop are highly folded, very much contorted and are cut off by the west by a large dike which runs N.W.S. =1034/dikey, 3 feet west faint The accompanying sketch is an enlarge- ment of the above line indicated at station 8. Station 8 represents more contorted & folded shales displaying a little syncline. On the east side of this syncline the dip is 45°-60°, S.70°W, strike N.15°W. on the west side the strike is 3.40°W, dip 75° to 5.55°E. The strata curves round indicating either a plain syncline, or one with cleavage greatly tilted. At station 8, the beds on the said side strike approximately N.87°W. the dip is very slight, 5° or less, direction 3.55.W. The beds are contorted 46 the axis of the fold along the slip. The major part of the joint line a markedly & abruptly different line of strike dips. This change in strike & dip is apparently a fault plane which extends northwesterly. On the west of this plane there is a series of beds which all strike 5.70°W. and dips 66-70 degrees, N.15°W. Near the middle however, a close examination will reveal the axis of fold, which axis is apparently on east. The beds represent a closed fold whether anticlinal or synclinal it is impossible to try, as the fold itself is turned up on edge. Station 4 is at the foot of the little red hill shown on the map in the middle of 3.54.F. The lower part of the cliff is composed of contorted siliceous dust beds displaying the usual network structure, apparently similarly to contorted ash beds or other igneous rocks different places of which are represented by 1035 1036, 1037. On the west side of this point also rotation of cleavage is pretty very apparent, as is illustrated by the following profile. In the ledges of shaled slates & siliceous beds at the eastern edge of 3.53.6.A a single Lingula was found. These are the same species. Beds as 3.55./o.e and 3.54.6.a The beds are very distinctly stratified here. The fossils were formed in the lakes contorted shales on the west side of Carrying Place Cove: P.S. This contribution may be interesting but show real I guess to go on, or Dr. Bate believe, nearly curved pressure rock slates rather than curved bedding. The folding at A3 appears & Co local crumpling of a few strata rather than close folding. The rocks 1035, 1036, 1037 also appear a little west of the first "O" in More Island where they appears to be well stratified and only distinctly strat- ified beds at this point they dip 47° N.20°W, Strike 3.70°W 47 KENDALL HEAD WESTWARD 3.55./a 3.55./b 1033 3.54.6.a 3.54.C HILL 8 20 3.54.8 3.53.6.A
