No plant impressions were observed in any of the little fragments that had fallen nor had any been seen by the superintendent or the foremen. To secure a complete section of the rocks, to the top of the bluff, fully 1,600 feet, would be extremely difficult owing to the abruptness of the face. If one may determine from a some- what close examination of the loose fragments up to about 400 feet, the result of the effort would hardly repay the labor. The softer beds are concealed by debris except in some precipitous portions, while the exposed rocks are flaggy sandstones. Evi- dently, one has here a succession of brown, gray, reddish and yellow flaggy sandstones and sandy shales with apparently some streaks of black shale. But from the palaeontologist's standpoint the detailed section might prove of great interest. Professor Nathorst collected from a ravine near the head of the bay the interesting series of plants, Tcenioptcris, Lycopodites, Baiera, Feildenia and Elatides, which enabled him to determine the age of the beds as Upper Jurassic. These remains were found in a black shale, but they are not confined to that stratum, for Mr. D. H. Morris, accompanying the writer, obtained among other specimens a block of sandstone with Tcenioptcris from a 1 No. 2 is by C. E. Munsell, yi?//?'. Amer. Chevi. Soc, xiii, 4. Nos. 3 and 4 by R. C.
