Well up on thenortheastern side of the bay is a valley which a stream drains, off themouth of which is anchorage. Westward of the stream is a ratherhigh (2,000-2,500 feet) ridge, recalling the Mesozoic mountains aboutTuxedni Harbor, eroded in benches and having a singularly artificialaspect. From the first bench on this ridge Mr. Purington obtained afew Mesozoic fossils, the most noticeable of which was a Rhynchonella,and a few others were obtained at high-water mark where the sameridge came down to the beach. The matrix was coarse and friable andthe specimens were few, but it seemed certain that the two lots belongedto the same fauna, which must range through at least 1,000 feet ofstrata. The rock is chiefly a calcareous shale, barren of fossils, which

Where a seam of sand and gravel orcoarse sandstones is interleaved with the shales, there the fossils arefound, bnt these seams are rare. We made the unavoidable mistakeof hunting inside the bay for fossils, while the fruitful localities nowappear to be just outside the points of entrance. KIALAGVIT BAY. Our next collecting ground for Mesozoic material was in KialagvitBay, a little to the west of Cold Bay. Here ammonites had beenreported to Fisher by the natives. The bay is long, and is defendedfrom the sea by a line of islets and reefs. The shores opposite arelow and grassy near the water, and rise gradually to hills of muchthe same type as those of Cold Bay, though wanting the benches, asthe beds were more steeply inclined. The grassy bank gave no veryencouraging prospects as a collecting ground, but we finally wentashore where a few small outcrop
