Aug. 7. Dalhousie Tuesday. Spent the morning in the cave beyond the high trap ridge. D.D. & Sturges Cave are next on page before this. Had very little time to collect or descend at all today. Clarke has most of the fossil points collected while I made the section. After pocketing and shuffling the single box completed to assist the elder of the morning. The tide was out and terrible for anywhere. On the Portamurus bed I found a number of Leptaena? or Pineaora. These came in just a few feet above the Portamurus. All my proofs are regarded to agree with the section on the page before this. I am more satisfied that the Dalhousie beds are true Devon, Holdbury but that the fauna is unlike that of New York and belong to another province. Further, that the Dalhousie beds in a general way correlate with the Cape Byron Cave beds which are away in a straight line 140 miles away. Clarke thinks about the same and finds that the Cornforth fauna is either the same or nearly of the age of the Dalhousian series. The Dalhousian beds must be the key to the base of the Cape limestone series. In Portley very a page and detail map of this region in Murphys hotel I saw there
