Tuesday, June 18, 1907 2 Blackford Head West of Blackford Head from the factory extended above as a fine series of exposures of olivagite ash or breccia. These ash beds differ from those of Kenilworth & Merthyr more plainly in having a lamprophyre-granuliferous matrix of the gray or slate-gray matrix. In glass this rock assumes the character of nearly ideal green olivinite but generally the fragment included are quite serpentinous. A few specimens no 1070 were collected on the west side of the road within of the house opposite the fish factory. no 1071 is a similar fragment from the shore 100 feet east of the factory, and extends along the included gabbroic. Throughout the rock these stand out upon weathered surfaces little cubes. Of splintering neatly white or cream color. These inclusions are large fragments of dark reddish glassy olivinite or plagioclase, small globules of light gray and pink laminar matrix remnants of dark nearly black basic lava, and dark 6:51 purple fragments. Some of the fragments cover three quarters of an inch. On the west side of Broad Cave (c. 008 N of Prof Williams) occurs a little patch of gray slate striking N 25° W. Dip 2½ direction N 15° E. Shales patch of shale as a flat 11 feet square had few rock and occurs at the east end of a olivinite flow. The real locality is just above the east cornering place the latter 5th, and on the west end of this little cave. The forest in three little patches include good numbers of ostracodes (Oysterella, ? Ophrimella, a few Cypricardate? (one specimen them 2 or 3 cardinal teeth), a few Mytilus = Crustacea? On the east side patch of shale is where it appears to be olivinite flow. Between the flow & the shale there is very dark slate like rock 1072 of the longest of which lava N. 10° E, out of the upper part is suddenly deflected into vertical and leans along NW. Here appear and contain large quartz non crystals dolomitic shale = 043. It appears to be intrusive into the olivinite or gabbroic olivinite with "fine lines" appears on both sides of it, up to the blade on the east, & extending westward. Wherever cliff is composed of a purple olivinite rock which exhibits horizontal flow lines and a weak subcolumnar structure. These flow lines stand out on weathered surfaces. A few specimens 1073 show than quartz well. The matrix is glassy & nearly dark purple, becoming pinker at spots one hundred & fifty feet the west the lava gradually turns gray or greenish and in such is quite gray. At a little point there occurs some ash & possibly flow breccia. A specimen was collect ed at 1075 showing the gray-green matrix. no 1041 B is a specimen from the hill north of the highway in west central 6:5: V. It shows the lavender purpleish inclusions & jellies. 2d rock composes this hill. Wednesday, June 19, 1907. as the head of Deep Cave, on the south side (opposite to) 3 mining work & then one foot like gabbroic rock, c 676 projects up into the olivinite without great cutting through. its olivinite continues in beautifully swept and covered sea cliffs (caverns underneath as those of joint planes) for about 100 yards eastward, where the pink olivinite is succeeded by a gray volcanic brecciated on faces of lava are sometimes black, occasionally dark brown. A few weathered amygdaloid stone in places in other rocks blend is 1077. These rock appears clearly the pink olivinite but the appearance so indicated in its figures may be due to recent erosion. The olivinite laden a roofs seen in the west above A (olivinite), and on the north side B (gray rocks) from antiquity of 1077 rock. The rock composing 1077 shows low ledges on east end, with the huge cliffs of olivinite rock. Figure 2 represents a little section in the westward of detached cave in the middle of the cliff gorge facing the model. 6:4:9 a" is the lower side on the south edge and represents a gabbroic 1075 olivinite very coarse N 250° W dip 45 on average of 40° take N. 60 E. "B" is a larger dark purple flow with almost sharply similar strike and dip. Weathered border lava is about 11 feet thick. (c) B is succeeded by some rocks 13 feet thick which at a distance resemble somewhat light gray colored shale, but when examined more closely are seen to be very finely ground left ejecta traces of a very light gray color with dark green spots and not angular inclusions of pink olivinite the latter 14 to ¾ inch thick nearly on inch thick. C is followed by some level beds. D strikes vary from 0-15 feet within a distance of 50 feet NW. Under the rock as with ash-like bed which is distinctly crowned on the upper part. E. The top of the section is formed by an exceedingly interesting masses of ash tides. The matrix is a very fine dark purple glass similar to many of the best fragments of dark purple olivinite in the Perry. Included in this mass of dark purple magma there stand out light gray colored spots which when examined are seen to be common glass Silicium chales. These shale inclusions are generally 1 to 3 inches thick; some of less rounded rarely a fragment 6 inches to a foot thick. Besides the typical light gray shaly bits which are included in fragments there are also included red and gray nodules that led figures similar to those occurring in 24:7. These final red fragments are some of them nearly a foot thick on.

24 5 There are also increased large clumps, a foot thick, of beautiful flow tricena along the flow line in the light colored internum. The margin of this flow is dark purple. There are also dark purple and obly [illegible] clumps, which contain fossils = 6.49a . Fossils also occur in other red shale gotbles and in x2 gray shale gotble. A set of Jurassic from separate getbles are labelled 6.49a B,C,D,E,F,G,H.R. 6.49C very much similar to the fossiliferous section of 6.75 of also below. external mold x 4 x1\frac{1}{2} getstone "little" structure In the little cove in fig.3 (S.W. part of 6.49 occurs a some line of exposure of shale about 250 feet long. The shale is friable gray in color, very fossiliferous in seams and contain scattered calcare lenses 1 inch to 5 inches thick & one to a foot and a half long. These values some directions are more massive for. The shales dip 66 and 76\deg for taken in a dipping N.70\deg E and strike N.20\deg W. About 10 feet of shale is exposed below a 12 foot quartzite sandstone which appears in place to fit of very friable dirty gray shales. Thursday June 20, 07 Spent in collecting fossils from west side of Blackford Head = 6.49 m, p.5. and the most lower corner of Broad Cove = 6.57a. p2.

Friday, June 21, 1907 In the northwest corner of Broad Cove below the letter A in Eastport empty two levels strata (only one on map) which run in their center portion over generally straight dip-marks of fossiliferous shale. The strata are gray in color and rather coarse. The calcareous seams are very abundant, especially in the lower level which are from 1/4 inch to 1 1/4 inches thick. Generally an inch. They are full of fossils which are unfortunately unrecognizable. A few fragments were collected (-6.5-6a). The fauna includes a few orthoids, a modioloid (not collected) and a rare Liguula. The rocks strike W. 70° N. x E. 70° S. and dip at rather heavy angles - 66° in the lower gray (recently noticed in place) and 50° in the upper part, direction N. 70° E. Perhaps 30 ft. of strata are exposed. Beginning just west of the little ravine (west of the middle of C.5-6, east of South of the letter E in Eastport, there is a series of long exposures of shales and calcareous seams, evidently of the same runs as the rocks including 6.5-6a above. The beds dip 45° direction N. 70° E., strike W. 40° N. by E. 70° S. The calcareous seams are here quite abundant, as in the preceding outcrops, & one calcareous band runs 5 circles thick. The gray shales resemble dirty beds in their fine grain & in the appearance of a network structure. The fossils contain some species of modiolopagoda. The calcareous layers mostly commence with k orthoids. A few thin bands of quartzitic sandstone usually finely banded, the fine bedding (stratification) showing cross bedding. A rare Liguula is scattered throughout the shales - a seam of modiolopagoda was collected. A muriciform - like gastropod in also present but very poorly preserved. Forms 6.5-6b. About 25 ft from the east end may be seen another fault extending N. 20° W., not the east side gray & blue with about 4 feet, x entire depressed about 4 feet. Showing contoller or seat (downthrown) side of fault. Just west the west end of 6.5-6 (at the west end of the little arroyo, north gate of S & W shore line on map), the gray shales are followed by reddish purple beds which feel like red shale but are not without the slightest trace of fossils and which greatly represent purple volcanic flows: there are no foreign inclusions. At this point a thin one foot belt of light gray quartziferous rock cuts across both the gray shales & the purplish beds. This also dips about 45° N.E., trend, extends N. 10° E. x or [illegible] 1019. Twenty feet this west the purple beds so again cut by a dike. This dike is thicker about 10 ft. across and extends N. x S. 25 x 1019 dirty feet west is another thick dike which penetrates up into the gray shale but does not go through and the cross cuts up a white covered with shales & calcareous seams. That the latter

8 ars older than the dike and not separated on the dike by any by their lens labeled at the contact, Dike 1050 and with 1079 and 1078 appears as a separate from a more like 1050 x 1079 appears to be the same offshoot. In the southern series of 6.5.5 lamellibranchs are abundant in the thin gray shales which appears at the same as the thin gray shales lower beds of 6.5.6a, These lamellibranchs are 6.5.5 a., The shells here dip 24° N. 12° W., Strike E. 10°N x W 100 S. (= N 90 E) Saturday, June 22, 1907 At the foot of the cliff on the east side of Blackford Head near its base after later B in Broad Cove there occurs a very interesting little exposure. A sea cave is worn into the tropes at the east of a jorum which runs approximately N.E. x S.W. On the N. side of this jorum deposits a little exposure of a sort of shale, (dark gray 651a) coarse sandy shales with a very characteristic frequent & wood copals fragment not collected), There is no trace of these beds on the south side, and the feature is just-- ally a fault. The shale dips at my high angle approximately 70°NE of Nock amount of dip minimum shales penetrated. The rock on the north side is 1053 that on the south is 1052. Both appear to be the same, a fine grained gray volcanic tuff which exterior lithologically, tells stratified beds of Kennell Head. In places the rock appears to include angular fragments of light-gray lava no. 1053. There are poorly fragment of lakes shales, No. 1052 as a single thin line kind of trap which is covered by thick mass beds of thin gray shales, perhaps fifty feet thick. These shales are quite friable strikes N 45°W. and dip ESE south-- west at an angle of 38°. They contain scars of lamelli- branchs and a few gastropods with some Lingulas and and in the same series with 6.5.5a and the general area of thin gray shales about Blackford Head & Broad Cove The brachi are 6.25.12a., The rock is free from quartzite or cal- careous sand concretions of thin beds of gray shale throughout. The lower part is not much folded & fragments are included in 1052 indicating that the latter is an intrusion. The upper 20 feet of 6.25.1a are extremely crumpled, con- torted & sheared into a massive wrinkled sheet. The rocks are quite dark in places and the glossy coal black appear- ances of the sheet has given ground a clean appearance of coal. This is one of the contact areas that has been regarded as a sort of field of flow; the so-called coal is merely the broken-- side structural shale in the upper part of 6.25.1a which, broken contact by the overlying volcanics. This volcanics represent flow of light gray lava including large fragments, a foot commonly, feet, or measurably 2.5 x 4 feet thick of another light gray Lava, 1054 one of these fragments. 1057 represents the native there resting 9 Shackford Head S.E. side. beginning 3.25° W. nickelinae of the underlying shales. A very sharply marked fault seams opposite the 4-st. standing in northern 6.25.1 (about 75 feet South of 6.25.1a which is at the north edge of the square). Into the fault is any slight, apparently on the same material as rock occurs on both sides, In the south side of this fault which appears to pear 325° W. the comboidal feature in the gray lava flows of finely developed. A hand specimen of this lava is 1057. On closer it is quite grimeous, a piece of grime is 1057 on another surface. The lava is in spots beautifully mottled with cream-- mixed areas. A mottled specimen in 1058 1057 is a dike which runs into through the lava post-1057 and bears 3.50°W. This dike also ends through the shales and across a very fault-- that bear 6. W. about 10 feet north and represents the area of the fault generally at regularly for some of the south shore cliff of this island and head the shale which are locally brought up, strikes in nearly the same direction as the fault, and displays a heavy drag of.

At the southeast end of the Little Graniteary in front of Blackford Head there is a fine series of porphyritic dikes. The dikes are soft pyroclasts then passing into medium calcareous basal bombs. The cores is dark gray, in places quite black & pesty, almost resembling coal. A few thin seams about an inch thick show network structure, but for the most part the bedding of normal slate. About 10 feet below this point were ignored. The lower 60 feet contain a few distinct outcords & small branch fragments with lingula fragments & little mud balls. These fossils are 6.25/ b. The portion of the series dips 27°, N 55° Strike N. 35° W. 14 is cut by trap dikes 1060 which runs N. 55° E. In the upper part of those forty feet about a few lamellibranchs were collected 6.25/ c. and close as followed by a couple of feet of very fine, soft black slate, containing lamella branchlets generally in shell, a few lingulae, and first numbers of ostracods. The ostracods are generally poorly preserved these forms are 6.25/ d. The upper 40 ft as pyroclasts ashes and several seams yield good lamellibranchs. Lingula's ostracods 6.25/ e. 6.25/ f is nearly on the strike 105° and dips at an angle of 2 1/2° to the N 158°. Strike N. 77° W. The dip seems in the strike and direction of dip appears 8 to due to the intrusion of the dikes 105° and 1060. The preceding rock dips out on the S.E. corner of Blackford Head and contains thin nodules along the N.E. corner of the Little Graniteary for perhaps another 75 ft stratigraphically, the black lava making a trap intrusion and contains concretions with light gray volcanics. The slate is horizontal toward the southern group of exposures but dip toward the north quite rapidly to the west of Blackford Head. The slate supports horizontally in the northwest corner of the Little Graniteary but we are overrun by the trap which is light gray in color by weight. The dike dyke cuts across the horizontal slate at a low angle, rising about 30 ft. in a length of 125° toward the north. Immediately next to the contact there is a sharply marked fine band in the line of the dykelet which is extremely porous & spongy. Above this the dykelet is light gray whiter & even lighter weight = 106f, but a few rods toward the south the rock becomes much more crystalline. Of a slightly granular-gray color, and include pink feldspathe crystals and ½ inch long. This rock makes up the mass of the joint and is 1002 at about 100 pts. S. of the northwest end of the granite the crystalline dykelet is cut by a coarse grained vertical trap dikes several feet thick = 1063.

Saturday July 6, 1907 (cont. from Tuesday July 2-07). Pleasant Point near this. Between the phyllite strike in 3.33.8 and the phyllite flow conforming the south- pointed cape in 3.33.7 there occurs in the little cove an exposure of MARINE CLAY WITH FOSSILS. These fossils may be obtained about 10 feet north of the purple phyllite flow mass and include chiefly The Mya (Macoma ?) like shell found everywhere on the present beaches Mytilus edulis and barnacles (Balanus) also Panope. No Pidda observed. The shells are the same as those living in a few rods away. The exposures are a perfect above extreme tide mark. The east side of the cape is composed of a purple phyllite glass = 1076 presumably a flow though there are no indications of flow except the glassy structure texture. There are injections into the purple glass of a coarse grained trap = 1077 which also occurs as thick dikes in the purple phyllite. There are several such dikes. 20 2-21.1 (3.1.4 A) 2-21.1 33877 33877 21

Friday July 5, 1907 Birch Point. (Section see p. 18) 22 (A) On the point between tide marks and continuing just above high tide are exposed sand 35 or 40 feet of which is coarse, sandy flag of a light gray color with a few slimy outcappings of purple shale. These chalk flags are as much as 6 to 10 inches thick but split into 1/2" to 2" slabs. Marine hummocks are abundant on these flags. Strike 5.75° W. Dip N 15° W, 26°. No fossils found in 20 minutes. No calcareous seams nor nodules. Near the top occurs one or two thin "cotton" seams; also a half inch seam composed of angular chert fragments. (B) The preceding are overlain by about 20 ft. of light gray, even textured chalk flaggy free-stone like rock which weathers nearly white and turns thin brown under acid but with no difference whatever. Strike S (approximately) 75° W. These rocks are exposed for a couple of hundred feet along the beach above high tide. The dip is 26°, N 15° W. During the fact that the eastern side of the point trends north a few degrees west giving an apparent inclination of the rocks to the east whereas the westerly side drops toward the west, there is this appearance of an anticline but this does not exist as the same strikes (S 75-80° W.) and dips (26° N. 15° W.) are maintained on both sides, and the apparent fold is therefore due to the bend of the cliff. The rocks include a few calcareous seams 1/2 inch thick and a couple of Oolitic bands (calc spidotic) 1/2 inches thick which weather cream white & contain Sporodites. The Sporodites were collected just below end of the top of Birch Pt. (= 6.13a, and a foot higher, 6.13a-2). Many of the layers contain large & distinct sun shrinkage cracks and a few contain fissures to rain prints; no more marks. The outcrop on the west side of the Point for a couple of hundred ft is at a small angle from the strike so that the rocks appear to nearly level. (C) For 75 ft. along the beach, the beds are abruptly disordered and bordered by lobing and the strike abruptly changed. Strike N 270° E x S 21° W or a change of about 56° giving toward the south. The dip is 27° W x 30° N. The rocks are flaggy flaky beds baked hard and a few thin calcareous seams and near the southeast end the rock is extremely brecciated and winded. There is here a fault trending N 15° W by S 15° E but the rocks on both sides of the fault are apparently the same except for the lobing, containing similar fissures & large shrinkage cracks and in one or two cases pebbles full which less are traceable. There is no strike in the vicinity. The top of the faulted area is formed by a chalk massive 5 feet thick which may be followed on both sides the fault but is not displayed either vertically or horizontally except to the south and this apparently at the angle of deflection of the strike where the fault is situated. The structure is evidently due to lateral torsion and deflection of the line of strike by a laterally thrusting force but without any vertical deflection. 6/3 A granite sill 26° Timber Cove Bell's Ice Bells' Cove 23 8

Kpt. Index July 5, 1907 Birch Point. (Section see p. 18) 22 (a) On the point situated tide marks and continuing just above high tide are exposed bands 35 or 40 feet of thick coarse, sandy flags of a light gray color with a few thin portions of friable gray slate. These chalky flags are as much as 9 to 10 inches thick but split into 1" to 2" slabs. Many limonite rocks are abundant on these flags. Strike S. 75° W. Dip N. 15° W., 26°. No fossils found in 20 minutes. No calcar-eous seams nor nodules. Near the top occurs one or two thin "cotton" seams, also a half inch seam composed of angular larger fragments. (b) The preceding are overlain by about 20 ft. of light gray, even textured thick fleshy free-stone like rocks which readily turn nearly white and turn brown under acid but with no interference whatever. Strike S (approximately) 75° W. These slabs are exposed for a couple hundred feet along the beach just above high tide. The dip is 26° N. 15° W. Owing to the fact that the eastern side of the point trends north a few degrees east giving an apparent inclination of the rocks to the east whereas the westerly side dips toward the west, there is an appearance of an anticline but this does not exist as the same strike (S. 75-80° W.) and dip (26° N. 15° W.) are maintained on both sides, and the apparent anticline is therefore due to the bend of the coast. The rocks include a few cal-careous seams ½ inch thick and a couple of Oolitic bands (Callo epodite) 1" chalky which weather cream white & contain Lepidocia. The Lepidocia were collected just below east of the top of Birch Pt. (= 6.1.3a, and a foot higher, 6.1.3a²). Many of the layers contain large constant sun drainage cracks and a few contain pelecoids no rain prints; no more marks. The outcrop on the west side of the point for a couple of hundred ft is at a small angle from the beach so that the rocks appear to nearly level. (c) For 75 ft along the beach, the beds are abruptly discolored and bordered by folding and the strike abruptly changed. Strike N. 27° E × S. 27 W. or a change of about 50° turning toward the south. The dip is 27° W. 50° N. The rocks are flat, fleshy slate baked hard and a few thin calcareous seams and lenses near the southeast end and the rock is extremely fractured and worn. There is here a fault trending N. 15-20° by S. 15° E., but the rocks on both sides the fault are apparently the same except for the folding containing cylinder fissures & large shrinkage cracks and in one or two cases probably a granite sill, some lodes are traced. There is no strike in the vicinity. The top of the faulted area is formed by a thick massive 5-7 foot bed which may be followed on both sides the fault and is not displaced either vertically or horizontally except in the bend that appears at this angle of deflection of the strikes where the fault is situated. The structure is evidently due to lateral tension and deflection of the line of strike by a laterally thrusting force but without any notable deflection.

(d). The normal strike of N. 75° E. is abruptly rounded via a little cutting of a purfuzzy layer in the shingle below high tide (= d of section), Beyond which for 175 ft. there is a covered interval and the next beds cropping out have the normal strike of N. 70-80° E. (c). These beds begin near the base with a massive (?) stratum of coarsely crystalline rock which was originally mistaken for limestone owing to its beautiful & distinct stratification, the stone effervesces under acid, and this partly interest- ing appearance in the appropriate the rock is really a granite (the strong resemblance to which was noted in the field. When the rock was called limestone). Two feet of this granite sill are exposed, the lower limit unknown but the sill cannot be more than 10 feet altogether since it is very steeply crop out about 5 feet below the base. This granite is 1075- shales granite sill B granite sill The relations of the granite contain a 12 ft. rhyolite dike) and the dykote are illust- nated in the sketch. At the foot of the cliff of shales rhyolite dike there is a single beach, and the granite sill comes up through the shingle directly in front of and cutting across the path of the rhyolite dike, a few rods to the northeast. However, at the point B there is a little fault and displacement in the granite sill, the fault area is under 5' as marked by a crumpling of the shale in the cliff. But the shingle, rhyolite boulders are common but no more so than anywhere else along the beach. To the east of the faulted area the granite sill has very few calcareous layers which do not appear on the next led where place must have been in the gravel trench between the cliff & granite sill. The suggestion that the rhyolite came up through B, and moves between here & the dike as a sill in the beach cannot hold, because this plane is the beach is largely if not entirely filled by the calcareous layers. Hence the cutting of the granite sill across the rhyolite dike, we real proves the granite younger than the rhyolite. The rhyolite is 1078. (Continued p.17)

[illegible] Tuesday June 11 1897 Starting At the railroad bridge crossing from Moose Island to Fox Island and following the indentant shore of the portion of Moose Island southerly we come in contact first with the rhyolite F of page 330-34, and the successively lower beds in the geologic section, all of which are exposed on the first point extending S.W. and just west of the house shown on the map. In the little core there are no outcrops but on the rock ledge extending easterly on the north boundary of the face is completely rhyolite. This rhyolite is quite coarse grained like same as beds "B" and "F" (section on page 33), but in one place on the north side of the point, the rock is greener finer grained and indicates a contact probably with underlying shales. In the little core on the shore line between the two rock ledges near the center of Eastport 3.44.7c there are no outcrops, but the southward of these two ledges as composed of Silurian shales and interstratified volcanic dusts. These dusts are red in color are very fine grained & resemble red shales but are not definitely stratified. They present a fine net work structure in contrast with the coarser stratified sandy shale seams interstratified with them. These dust seams are not continuous, but pass into stratalings shales on either side, the red dust appearing as patches in the shales. The strike of these shales & dusts is N. 80° W., dip 27°, E.N. 5° E. There may be perhaps twenty feet of strata so kind point of which the lower half are wave and ripple marked. In the middle occurs a gray shale showing finely preserved anna-shrinkage-cracks filled in solid finer gray shale & also showing rain drop prints on the same surface. Slim together with the now marks & presence of fingalines indicates very shallow-water beaches or tidal flats. Fossils occur in both the gray shales & in the red dust beds. Lamellibranchs are common in the latter, [illegible] (morderpsis), bivalvata, lingulace rare. The lingulae are uncommon in the gray shales. Fossils 3.44.7c. These rocks are much preserved and pyrite crystals with some calcayte are abundant & not near the fissure a specimen with pyrite was collected No. 1011. At the south tip of this point, there occurs just covered at high water) a three feet layer of embedded red volcanic dust & which also appears in the tiny core 75 percent southerly. Have some red dust bed shews no lamination, but as usual is finely laminated with exhibiting fine reticulate structure. It is capped by a third with [illegible] plane ash. Some specimens of the volcanic ash are labelled "3.44.7e" and of the underlying dust beds 3.44.7c." (The dust is usually a deep purple red but no ground green in spots. Six specimens collected are greenish.) In the [illegible] (at high tide) just S.E. of the ash & dust beds some more fossils were collected. The rocks here are red fossiliferous shales' red dusts & gray shales with a few thin sandstone bands in calcareous lodes and nodules. Dip 70° W.5°. Strike E.W. Fossils Lingulae? morderpsis?, Serpocida (Bothrophus?) are abundant here. These rocks, Eastport 3.44.7d are 30 or 40 feet stratigraphically below 7c. The shales containing with a dip of 27° strike nearly E.N.W. to the south as far as the beds cross shown on the map, at the east marked in blue pencil occurs a solid continuous layer of red dust (spot check) with the usual net work structure just like the dust occurs a layer full of angular shambes of [illegible], ash fragments and also containing fossils.

(a) [?] Irediolopside). Nearly opposite the house there is a loose dike cutting across columnar dust like v slakes. Long “horses” of the dike are intruded into the shale & dust beds, v horses” of the latter are included in portions of the dike. The dike appears to strike N 38° E, but this may not be the real direction. Underneath the dike is a one foot layer of volcanic ash - which may also be placed on the more the point 3.W. of the house. The strike of this ash bed = N 80° E. Marine clay (stratified) occurs in a little gully as indicated on accompanying sketch map of S part of 3:44:7. The clays differ from the usual massive gray (unbedded) clays in being composed of pink seams of red clay, apparently derived from the red dust beds & Silurian shales a few rods away; these red seams interstratified with thicker layers of clay of the color of normal boulder clay. The red clay seems to “stick” well, the dark yellowish brown clays 4 miles to a foot thick about four feet are exposed dropping walls - apparently under the till. The strata of clay are thrown into minute low domes or wrinkles and are not flat, though On the nose-like point in the southern part of 3:44:7, southwest of the house shown on the map, is a fine series of dust beds & two volcanic ash beds with shales. The northern half of this nose is entirely free from red beds - so as in the strata studied Monday June 16 (see p. 35). The red beds dominate the section of Silurians from the northern half of this nose-like promontory as far north on the separate dike at the upper cliff of 3:44:7. They are entirely south of this limit in the region studied, - the lower shales being gray & flaggy; the red shales red dusts & volcanic ash like reppars on the northern end of the island just east of the railroad bridge (covered at half tide). The volcanic ash bed, apparently the same as that described above (dike 7) - yielded a few specimens, - contact 3:44. 7 ashy. A thin dike may be followed for many yards below high tide mark.

A couple of specimens of the lower conglomerate are dated 3:44.7a, the upper conglomerate 3:44.7b. Pt. Bridge [Silurian] exhibiting the preceding forms the first ledge now just at the house shown on the map on the north shore at the end of the rd road (this house is now no more, its site is marked by ruins & the foundations). For one a hundred yards the Silurian strata extend northeastward with a dip of 34° N. 5° E., strike W. 7° W.. The lowest beds are exposed above high water just west (a couple of yards) of the ruins of the house shown on the maps. They are gray shales which are unbedded and intact for three or four feet contain several seams with numerous numbers of bivalve, oposid lamellibranchia and ostracods; the Lingula is also common. These fossils are constant 3:44.7a. A thin seam in the middle of these 31/4 feet contains so many shells & ostracods that it is calcareous. This calcareous seam (1 inch thick) and its fossils via 3:44, 4a². Away all the rocks of the promontory (covered at three quarters tide) are gray shales & flaggs with a couple of flacher flags or sandstones. Very little red shale - if apparently little of any dust beds (truffs) occur. The red shale is confined to a few thin patches & beds 40 to 50 feet from high water (along line of dip). These red shales yielded a few lamellibranchia (modi-copoids) and a Lingula 3:44, 4b They are a couple of feet below the lower ash bed, - 3:44.4c. As the second or eastern of the two points shown on the map, - that is, the easternmost of the ledges shown on the map in 3:44. If the structure is somewhat as follows "A" (a) is a fine grained basic dike, cutting across the edge of the Silurian strata. The direction of this “A” (a) -dike is N E. 5° S., & W. 5° N. A hand specimen is numbered 1014. The dike exhibits a width of six or seven feet; its southern limit was not shown (covered with gravel). On the east side of the ledge there is another dike “B” of the sketch which is directed N. 16° W. 36 37

38 the angle included between the dike and a " long to 69°. The dike shows 6 feet of width with the eastern limit embankment. A hand specimen in 1015. The next dike is exposed in a little cliff, which unlike 1014, 1015 shows above high tide. 1016 represents a dike (1/3 of the sketch) which strikes N. 19° W. It appears pretty the same as the dike 1015 (1/2 of the section) of width. It is a continuation. It may be fifteen feet wide. A yard or two to the west of 1016, there is another dike a few one, 1017, which weathers nearly black. This dike (1/2 of the section) is two and a half feet wide & is separated from it by several lakes & shakes with an occasional lingula. The strike of the dike is N. 4° W. 1016 distinctly cuts across 1017 on the gravelly beach, as is indicated in the figure. Following the shore eastwardly, in the little cove in the western part of 3:44.5; between the face and the rock ledges mapped, (just west of the latter) the shales are crumpled and turned on edge - strike N. 85° W., dip 60° degrees, 3° E. of North. The cause of the crumpling is apparently the intrusion of a dike of amygdaloidal diabase with calcareous amygdulæ, but different in color and the rock is similar superficially to the dike 1012. (see p. 36 top). Beginning at the rock ledges shown in the western part of 3:44.5 and extending eastward for about 1/2 of a mile as far as the rock ledges shown on the western edge of 3:44.9, there is a beautiful section of red shales, red & gray clay beds volcanos shales, gray basins gray flaggy. The rocks are exposed in a shore cliff striking diagonally across the line of strike, which traverses the strata in beautiful sections dipping in a general westward direction. The section begins on the east (the points for section) with an igneous dike resembling the contact phases of the rhyolite. Specimen 1019. This dike is at least 20 feet thick the east limit unknown, the beach from this point eastward being gravelly as far as the large igneous cleft & sea cliff beginning near the east edge of 3:44. 9. To the west of this dike (possibly a flow) there is an enormous bed of volcanic tuff over 6 feet thick, red in the lower half, gray green in the upper half. This in turn is surmounted by a massive vol. canic ash which contains fragments two feet or more in thickness. The strike of this conglomerate ash bed is S. 60° W., dip 36°. In the ensuing section of stratified flaggy etc there occurs several more tuff beds # at the east of the two heavy shore ledges near the western edge of 3:44.9 nearly due north - a couple of degrees to the west from the west extremity of the group of houses shown on the chart. 3:44.5. 3:44.9 39 usually red in color, and with fine network structure; extending interstratified with the shales thin flags, but the tuffs themselves not stratified (stratulate). The dip & strike of these beds is variable. Near the lower third are seen a few thin flags with calcareous concretions. On weathered surfaces these concretions stand out as coarse knobs. Similar beds occur south of the noted streams in 3:44.6 & 3:44.7 (near border line 3: 44.7 and 3:44.1). The strike of the ash bed has already been mentioned as being S. 60° W., dip 38° N. 30° W. Just west of the ash beds the shales dip 37° W. 55°. Strike N. 5½ W. A little farther west in the highly calcareous-concretary shales the strike is S. 45° W., dip 27° N. W. In eastern gart of 3:44.8 occurs a very thick pink rhyolite dike strataing north and south and more than 25 feet wide. It contains large scattered nuclei of opalite nearly half exposed black near the top of these sections into shales & samples of white rock of the dike 1018, occur some Camellibranchia. 3:44.5 on. For details of lower part of section, see p. 45. A pink spume (Quince) also formed in a calcareous mode off lower sound (= 3:44.5 bk., July 6, 1907)

Thursday, June 13 1907. A section was made to ascertain the THICKNESS OF THE LOWER PERRY as exposed just north of the first bridge across to Moore Island. The section begins on the shore at nearly low-tide; the rocks here strike N. 10-12° E and dip W, 10-8° N. The section was run along a line extending W 10° N or along the line of maximum dip normal to the strike. The section begins at some ledge which are covered at low-tide and which include the first exposures N. of the Hill Bridge (about a quarter of a mile). "a" - A continuous series of compact conglomerate with the pebbles mostly the size of peas, very commonly one inch to 2 inches. A very small portion of 1% of the pebbles are as large as 5 inches in thickness. The pebbles are for the most part rounded but an occasional seam a few inches thick line more than half the pebbles angular. These sandstones occur but these are Canisterlike and visibly cap the little ledge of conglomerate. A thin sand stone line (2 feet thick) strongly cross-bedded as found at soft (from the beginning of the section) but this line thins out to nothing 50 feet to the north. A thinner hard sandstone band four inches thick cove a edge at 30 feet. The thin sand is a little more persistent. Dip, 25°. "b" - Covered for 165 feet (110-275 feet). This portion is a much flat course few pebbles & there small. There are no rock outcrops but at the south end we a patch of gray marine clay indicating that the little cover is probably a buried channel running along the strike of the rocks. "c" - The first rocks reappearing are the edges of some red slates which are partially buried in gravel. These continue the same strike (N 10° E) as the preceding and like "a" also have a heavy dip to the west, though the exact amount could not be accurately determined. The slates cover a space of 9 feet (275-284 feet). In color they somewhat resemble the Silurian red slates and like these are also slightly green in connection with spots but are coarser & sounder than the Silurian red slates, and are just so crumbly or flakey. The Perry slates breaking into long ear slabs and being in places nearly "slaty". "d" - A sheer cliff at high tide of conglomerate, the cliff varying from 5 to 10 feet in height. The conglomerate grade downward into the slates in a fairly gradual passage; the rocks immediately above the slates being somewhat stony sand in many places free from pebbles & the pebbles where they first occur are small. The conglomerate becomes more & more massive above. The pebbles are rounded and nearly not more than 1 or 2 inches thick. The bulk of the pebbler are little, rounded white quartz fragments. The size of a pea & forming the cliff of conglomerate along the shore which is also along the direction of the line of strike, we find the character of the conglomerate varying; in place the entire 5 to 10 feet are massive conglomerate. In other places there appears some thin sandstone courses 5 or 6 inches thick and thinning to nothing in the course of a couple of yards. A poor precise reading of the strike over an extended stretch gave N. 12° E, instead of N 10° E. N 12° E represents the real strike of the section apparently.

Perry Pebbles in the conglomerate (all from Les K.) 1021. A soft black coal fragment overlying gray shale. The black coal- 43 like color may be superficially due to manganese stains. A few similar pebbles observed; all smaller, more or less inch thick. 1022. Gray shale occurring as a rounded, water-worn pebble in the Perry. 1023. Dark pelite porphyry with vitrified glassy spherulites. Similar pebbles are -quite abundant, though less so than the granite, quartz or pink felsite. 1024. Pink granite. Very silicant. 1025. Dark redish-buff grained felsite rock. 1026. A stratified red sandstone like fragment occurring as a delta. Perry 1027. An angular mass of plainly lower Perry rock occurring as a pebble in the sky 1028. Miscellaneous assortment of pebbles. 1029. Large examples of Perry conglomerate (pebbles smaller than usual). Section continued. "E" Severed gap, 290-505 ft forming side hill. "f:" 535-536. sandstone & conglomerate in a low 5-foot ledge; Strike N.13° E. Dip to meet, amount uncertain. "g" Scattered ostracop in the sides & in the rounded mass & All these ledges strike N. 10°-12° E. and dip to the west the amount of also unknown but in places apparently about 30°. (g) A two foot ledge of very coarse sandstone. (h.) at 675-695. a 4ft. ledge of slabby sandstone including fine pebbles in a very coarse sandstone. Dip 24° W. (i) A series of about 10 ft. of very coarse grained sandstone (very coarse grained) until hardly any pebbles at all. Strike N.10° E. Dip 26° W. These less ostracop in massively 100 yds. N.W. of first ledge. CARLOW ISLAND. June 19, 1907 348 In the afternoon a trip was made to Carlow Island. The shale were observed in the southwest grid of the island striking N.55° E and dipping 23° northeasterly. First north of a large trap dike in gray shales right at stratified land, which makes up the whole advents of the island. over some seams of modiolopsis and lamellibranchia and Lingula. these fossils are 3.43.6 a. The staly beds of the southwestern part of Carlow Island are abundantly wave & ripple-marked, and rain prints are very common. A porphyry dike cuts across the shales and illustrates first contact planes. 1033 is the normal porphyry, 1 yd from the contact. 1034 is the contact phase of this porphyry, 1 foot from the contact. Just above thru porphyry dike occur shells containing both Strickleya crassa & rain prints on the same surface. Some shales occur in a little carhood but near the south end of the island X-anton (not collected) the same lamellibranchia as 3.43.6 a. (Dike cut is not the same as 3.43.6 I, p.75 which is at the middle of the island).

Friday June 14, 1907. Pleasant Point. The next spur of Barlow Island is composed of the nearest peaks displays beautiful exposures of which are visible both east and west shores as well as looking up in the railroad cut. Passing to Pleasant Point by the railroad bridge we find no outcrops on the western end. Looking up the east shore the first outcrop occurs on the point—the southwest corner of 3.33.9 and consists of the intrusive gneiss rocks to associated with earlier and ground gneiss which actually probably represent contact phase of the phyllosite tely, grade into this latter also strikes five granite rocks both in quartz clay except possibly to layers of metamorphosed slate or quartzite. A specimen of the gneiss phyllosite as No. 1030, of the dark rock 1059. P. Rounding the principal ridge of phyllosite are found a thrust dike of fine porphyry bearing N. 70° E. The geography, 1902, is distinct cut across by the phyllosite. On its west edge of the phyllosite for several feet in contact with the shurran slates or fine grained s' grey in color (= contact phase) and the shales overlying are highly contorted. For 50 to 70 yards beyond the contact the shales strike S.W. 25° W. make a dip of 80°-90° W. or nearly vertical. The next 15 feet the shales strike N.W. by E. with a dip of 30° S.W.—these indicating the great disturbance caused in the shales by the intrusion of the dike of phyllosite. In the eighteen feet of shale with a N.W.-S.E. strike & S.W. dip of 50° occur some fossils—a seam with lamellibranchs? A several species with LEPENDITIA. The fossils are 3.33.9a. This thin series for a limited distance along the beach (presumably across this strike) a series of shales constituting the main mass of shales of the island like the Pleasant Point. These shales strike N. 21° E. and dip 28 degrees W. 20° N. They contain fragments throughout in a few same Ostrocods, and in some cases small little impressions of what may be an accidental Lingula. On the lower ford and a cliff of these shales exposed above high water (see below) there occur a couple of mines containing good number of Lingulae, apparently relatively an numerous species seems to exist. These fossils are 3.33.9 b. A foot and a half long in up is another very fossiliferous seam or rather two of these seams close together containing many others (Reydicola Ormista beside Lependitio & lamellibranchs & a nice Lingula.) These fossils are 3.22.9 c. At about 50 yards to 20 feet stratigraphically above 3.33.9 c there seams contains numerous members of Lependitae (common thin shelly) as well as and the Phionomphala subulata, good number of Echinia (Lependitio & nice Lingula.) These fossils all lumped together for 3.22.9d. From this point up to summit of bluff that is described in previous pages are three feet above (in shales) a synclinal break beyond which a few feet of slates crop and on the beach striking N.E. 5° W. and dipping 20°, S. 48° E., these resemble the beds above No. 3.22.9d in being sparsely fossiliferous but contain an occasional Lependitio to what this wreck is merely a synclinal fracture without appreciable faulting. Fossils 3.22.9e. This seam appears to dip beyond which there seems very much crumbled fractured suggesting a subterranean dikes rather along the head (see Hayward watch, the Lependitia beds reappear in the northwards strikes of N. 40° E. dip 20° N.W. These beds are properly ripple marked and one layer displayed same prints. These ripple marked beds are also displayed on the west side of the point. Saturday June 15, 1907. CARLOW ISLAND. After finding that the Lependitio beds included all the Silurian deposits on Pleasant Point a search was presented to find out if what extent they extend. In view above this continued southward on Barlow Island. The lamellibranch beds 3.43.6a (page 43) were followed along the shore, then entered the more marshy, rain-putrid & muddy blackish grey later calcareous mudstone layers & quartzitic seams with only an occasional lamellibranch, until reaching up to the railroad cut, the notably one containing shells; this cut includes the latter 2½ W.15° S. from the house) where some coarse slates are not by a phyllosite dike which appears in the west side of the railroad on the eastern side of the cut the shales continue uninterrupted & nearly so, and contain Lingulata within calcareous seams. A Lependitio occurs rarely through that the shales but there are also several seams of lamellibranchs with some Lingulae. The fossils from this cut are 3.43.6 b. Some Ormista also seen, but no Echinia was observed here. NORTH SHORE OF MOOSE ISLAND, WEST OF KENDALL HEAD. (Fig.1) In the long series of Silurian shales & slates occurring on the north shore west of Kendall Head—on examination was made for fossils in the lower part—the formation in the upper beds being represented by 3.44.5a, 3.44.4a, 3.44.4b & 3.44.4c. From one west of the dike of phyllosite (= contact plane - 1019), near one Lingulata; these Lingulae are formed within a joint of the dike and are the only fossils found for almost a foot above. They are not common (= 3.44.9a) 3.44.9 b includes some more Lingulae a few feet above the preceding and two feet below the dust beds. Fossils occur but very rarely, however in the red dust beds where attempting to frame an occasional fragment of shell in external molds of Echinia; Lingulata & small muds paws I am uncertain which the dust beds are to profit to find any recognizable fossils. For twenty-five feet above the third shales an occasional Lingula may be found—very rarely twenty-five feet a low the fourth ash bed occurs a seam of lamellibranchs 3.44.9c and about ten feet to a seam with large Lingulae. These beds are just below some red dust beds. June 16th 3.44.9d Lingulata beds in grey shales, about 75 yards east of N.W. phyllosite dike phyllosite. (See Bottom section for locality & place in section) June 27th 3.44.9e Lingulae in red sandy layers 26 feet east of phyllosite

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
