Wed. August 20, continued. In the afternoon started north and down in the sec- tion. The dip of our conglomerate (1) of Pointe St. Peter continues north into the first harbor to a little point, and then on north making the headland of Little St. Peter. Around to the north one can see about 45' but thickness of this cgl., but with all fit to regret any of it much thicker. Thus very little dip, but other bear is in to the south. All of the remarks on the previous page relates to this cgl. To the N. around Little Pointe St. Peter in the clay core beneath cgl (1) is a series of thick bedded sandstone with thin lens of cgl and shale falls. It is decidedly arkosic and the red feldspars are conspicuous, quite irregularly bedded and much eroded. The thickness or all exposed is about 100' (see 200') thick, and to the next cgl (2) maybe 220' thick. The dip is 18° S.E. (from an unnamed point to the N.) To the N. in cgl (2) and in little (1). There may be lens ls. estimated at 750' and the beds are somewhat smaller. Thickness at least 60' The dip is to the S.E., i.e., to the south and to Plateau Island. Below cgl (2) going N. is very much more bedded ss. Weather reddish but inside tends to be greenish, with local lens of cgl. a few inches thick and an occasional local lense some feet thick. Portable thickness 125' Next down is a local cgl. as at me, about 10' thick at center soon petering out to the N. Dip 15°-18°. Going N. the dip flattens to less than 10°. Bold away from the dip on 12°-15°

Pointe St. Peter, Thursday Aug. 21-1930 Had lunch wit me and spent the day scanning the "Bmarantine" cliffs north to Red Head. Started from north side of Pointe Harry Cngl (4), which at the top if the cliff is about 16' thick. Its worn surface (Whale Head) estimated at 60' is mud-cracked. I don't if this cngr. is more than 20' thick. Later. Then it occurs regularly bedded thin and thick green SS that create a dull red; all are decided iron-bedded. The craser SS are still very arkosic with the red feldspars conspicuous, but less common than in gounpa beds. Nearly all of the more prominent bedding surfaces have red weathering clay-falls in a thickness of a few inches up to one foot thick. Here and there are short lenses of sandy cl. Also the first evidence of land plants, circular to oval or flattened small stems that branch occasionally, all show a fibrous nature and often the outer part is coaly with the center (layer) filled with mud or sand. Saw no leaves of any kind. Probably all are Poil affgen. These come in about 100' beneath Cngl. (4). There is also a little of silren mica present. Saw a few current ripple and current surfaces = river action. From here down the land plants are always present - rare in solid SS and not common in shaly thin-bedded SS. The thickness down to water-face is about 300'. Here then irregular beds of green cl. At the falls the dip is 20° S.E. Same SS series continues below. At 300' beneath falls saw a fine smooth? faethford trail, about 3/8 inch wide and about

"Corner of the Beach, Tuesday Aug. 26th 1930" Got here this morning at 9.15 and before 10 o'clock was in any way to see the cliffs to the south west. The head of Malta has a sand spit several miles across from the south with the Tickle at the north over which the rail way has an iron bridge. Back of the spit is one of the large Barachris of Saffo and it maybe Clarke's typical example. The R.O. of Barachris is on the north shore of Malta just beyond the Tickle and where we leaves the R.R. In Pointe St. Peter. As we gets to the "NW" end of the cliffs looking to high south shore of Malta we one meets with about 50' of interlaced dull- ned weathering fine grained arkose ss (from tram '13) and a crassie greenish-grey conglomerate. Towards the top the boulders are small under two inches but in the lower part one much larger up to six inches or more across. In the higher conglomerate about ½ of the boulders are yellow stained well rounded vein quartz usually under one inch thick down one 2" long. There is chief material but jasper and granite is comparatively rare, along with a little of siliceous stones. Limestones are not common at the top but below is the dominant rock and all look to me like Grand Trenches, due to examples. These are the older Saffo Sandstone Series [but are again separated as Ganne de Pyto = Pompeian Formation]. In the greenish-grey ss there are beds with an abundance of cutinized plant fragments and among them are pieces that look like Psilophyton. In the lower conglomerate, there is an abundance of cutinized lumps, one is 8" x 4"; another 6" at top 10" below with coal layers on its outside.

Thursday Sept. 4 -1930, Continued On getting to Carleton Drilled W about 1/2 miles to the shore exposure and at the crossing station on the R.R., to where the Bonaroutine is exposed, as I trace in this trip from the car window. Here the engl. all stands or end dipping 70°-90° S.E. into the Bay; to strike N., N.N.E. It all looks like true Bonaroutine and it rules the hyper Germanian as we knew from the Inguasha Landing at Jacta Point. It can be seen W. of Carleton along shore for about 1000'; and again to the E at the W. "Limit of Carleton Village" in the brook where the R.R. and auto road crosses it. Here to dip, in about 30°-5 into the Bay. Here and there in the critical beds one sees large sun- facies slitten-sided horizontally or somewhat tangentially. The thin here could be some hundred & 7 feet, on N of which is a cross engl and as he thk come in the high out of the s with thin sheets or plates ofponge porcelin cut nearly str. as at Jacta Point. The auto road does rise over it and in places one sees the engl coming to road. Amongst the pebbles are rim cratered as in the regulatin Bonaroutine. In this place the Bonaroutine does not have much ls and red sh., orange Pierce to yellow and clean blue ones, mostly large ss, and occasional small sponge commun. The ring quartz particles are small usually under 1/16th inch and well rounded. Low mg granite, and but me grain boulds. Jasper is rare but in places is more common and up to 3" across. There is considerable of a thin red dust sandy

St. Albans, Vt, Saturday Oct. 18 1930 After being camped butas Mrs Knoff did not arrive until 8.25 we did not get started until after 9a.m. Went north to see the Swanton (= Keel) cmyl. All were thrilled at the evidence but no one was finally able to prove if the big ls about 60' long was broken or a lentil resting on the Highgate slate. The bigger one at Rockledge Lamprell felt might be a lentil in the Highgate slate and on which the Swanton cmyl formed unconformity. Then stopped to see the Swanton cmyl, a little north of Keels Corner. Here it soon became evident that the Swanton cmyl lies angularly unconformably above the Mallett sandy (and a quantity of dike cuts cut both the Mallett and the Swanton's dolomite). In the opinion of Lamprell and myself that in close of the Cambrian (i.e. after Highgate slate time) the C. [primary not strong but at least enough to make an angular uncon] was deformed and eroded before the early Ordovician [Bequia] sea thus spread across a hemmorary surface, cutting down the elevations above sea level and making the local lenses of Swanton (= Keel) cmylomite. Long-wrecc caps lie dips and strikes of the C. formations is different from those of the Swanton cmyl. This then proves that the angular unconformity Keilt, Remtara, and down 1/2 mile south Canadian bridge is actually an unconformity, and that Raymond is wrong in saying due is more here. The great holes of ls in the Swanton cmyl puzzle us. The apparent flow structure may all be due to a calefplown
