Sunday Sep. 14 - 1919, Quebec. Heavy but broken clouds with the wind in the faster direction for rain. I wonder if it will? No, it was a fine day. Started out to study the limestone conglomerate. First of find the one on Main street at the point where the three off sets come. Beneath the coal, here about 10 feet thick, occur a fossil filled shale about 3 feet thick. Into it has been dropped sandstone and limestone boulders 12 to 18 inches and the boulders always show depression around it as if dropped into the still soft muds. This cannot be due to the defor- mation as the shales do not show flowing in a given direction. The boulders are of all sizes up to 4 feet across and some flat ones are 5 feet long and for 14 to 18 inches thick. The great majority (99%) of the boulders are massive clumps of light blue to dark colored limestone, and about 3/4 of the masses are of flat lime- stone up to 2 inches thick and 18 to even 24 inches long. They lie at all angles, though there is a general flat arrangement and the whole is cemented by a very fine sandy paste. The smaller pieces are more rounded and for the larger there rocks,
