Two samples taken from 1405 and 1420 feet respectively, that had been selected at a significant change in lithology, contained no foraminifera, but are considered from their general appearance to be Mesozoic, probably Cretaceous, sediments.

Three samples of diamond drill core from 1550, 1570 and 1590 feet depth were examined. All are Cretaceous sediments, the lowest at 1590 feet being a glauconitic shale of marine origin, with Cretaceous foraminifera. This is the first record of marine...
