July 24th 1918 Wednesday Middle Arm Bay of Hinds Left Curling at 8:30 in a dark stormy morning. It rained hard during the night. At 11:45 we are inside of Middle Arm and in the fishing camp house of James O'Roake on Croft. It is here that he comes to the face to catch kenny until late January. His name is Ben Brads Croft. Before lunch we looked at the rocks but so far have failed to determine the age of the strata. It maybe that we are in the Lower Cambrian. They are dark blue-black shale with thin beds of limy sandstone and partly there may also be many thin beds of laminated sandstones. Crinite spores are present considerably parting limestone there are also occasional thin gyres of intraformational conglomerate and at least one gyre of conglomerate in which the fossils are up to 3 inches thick as the specimens of Lower Cambrian age, but many horizons in the laminated sandstone are many fragments of their shell lingulids. It is this evidence that leads me to believe that there was due a joint thickness of L.C. To the north from camp there are parallel beds and thin conglomerate. We tried by aim at this area in the evening but found no fossil evidence very little. There are many thin gyres of intraformational conglomerates and at least two thin ones, one about 4 feet thick the other 6 foot thick. In those two conglomerates the pebbles are all of thin flat pieces face size up to 12 and from 18 inches across. They are usually of two thirds and both look to me like the strata in which the crinoids creeps. The small pebbles are all well rounded but the large pieces may be quite angular. To me it seemed that the pebbles came out yet hard when they were incorporated in the conglomerate for many are bent to fit into other pieces and one sometimes crooked. The dip of this series is very hard to make from 30 to 45, more usually which I cannot remember. I do not think this formation can be the Tally Head series for we then should have found some of its fossils. Furthermore there are not enough of limestones to agree with the T.H. formation. On the other hand the
