July 24. Middle Arm. 77 form of thick lelled liguila in Ordic is a decided character for Cambrian age. If it is not Loro Camh, it may be that it is Upper Cambrian. Certainly it does not agree with any formation seen before. The thickness is considerable and may be several thousands of feet (1020 fathms) In the afternoon out boat troll up to the head of Middle Arm To the northward in Penguin Arm and to the southward in South Arm at Penquin Head + to the high head known as Penguin Head. We went ashore and found it a thengon from me truth. Take the lorn dolomite seen at "Limestone Quarry" in the stream. The thickness appears and True what we had in the streamer, about 1500 This lend seems to be of quiet face, rights raised, To 2000 feet. Then followed the equivalent of the schist series, here far [around the word] less metamorphosed and lying in undulating and locally marked folds. The same is at the pretty Ragland Head. It's an immense magnesian series and shows creathery phenomena like that seen at the outer station along the Drembar River. In the Towards the south-east across the big Ragnachris distance we saw the several or higher and thicker dolomite series all [orth-] dipping Towards the east and striking about N. 30° E. See page 83. There is no doubt that one estimate of the thickness of the Portugese seen in the streamer is correct. Now we see that there is a succession towards the east and that the two marble series are distinct, separated by the middle schist, and followed to the east by another and distinct schists. The two marbles are not duplicates of one another. Accordingly the great Portuguese series is a continuous sequence and the two marbles are of different ages separated by the third schist, here in Middle Arm - a long-shaly series also of great thickness. To the east of the supposed Cambrian series there is another formation before after D. had seen it; I.C. of Ormy Bay leaves certain that the style belong one side of I.C. age. (See page) The Portuguese marbles come in. This he did not discerning. The two have normal dips. A3
