three. It is remarkable how scarce the buchisprds are. All that we saw today are small Rafinesquina with a median keel. Torohyle or Jan has found all the entire trilobites, Bygga or saw one today. June 11 is essentially a heavy bedded finely laminated that slathers into a shaly gravel under the influence of the weather. June 10 is also heavily bedded and shatters into gravel on weathering but in some one presion. It is far less fossiliferous than June 11 but the species and especially the gastropods are apparently the same as those of the higher zone. Of Euryptomites it is impossible to get good material because the chambers are filled with coarse crystals of calcite and it is only the body chamber and 2 to 4 from first chambers that are filled with mud. Then too many of the shells were rotten before covered as the under side has broken down and flattened before fossilized. Nearby all the Endocrinatidae were also rotted before covered as the under side is nearly always gone. The chambers are nearly always filled with mud but the endocore is nearly always crystalline calcite except the outer part. The strike near the fifth range M-70 ft. Dip 12 deg. One and half miles farther inland strike N-40 ft. Dip 10 deg. Saw a piece of the Lower Cambrian conglomerate of Labrador as an erratic today. It may also have come from the eastward area there seems to be L. Cambrian.
