LOWER CAMBRIAN TERRANE 305 



Hanford Brook section of New Brunswick. As my study in 

 1899 began with the Smith Sound section, and it was there that 

 the Olenellus fauna was found in the central portion of the ' Pale- 

 ozoic terrane beneath the Cambrian,' that section will first be 

 noticed. Other sections of the Cambrian rocks of southeastern 

 Newfoundland will next be taken up, before^the New Bruns- 

 wick Cambrian rocks are considered. 



Mr. S. Ward Loper accompanied me, to aid in collecting fos- 

 sils. Mr. J. P. Howley, Government Geologist of Newfound- 

 land, joined us a few days after our arrival in Smith Sound. 

 From his intimate knowledge of localities of Cambrian rocks, 

 acquired when making the geologic map of the Peninsula of 

 Avalon, Mr. Howley was able to guide us quickly to the best 

 sections and exposures about Trinity Bay. Except for his help 

 it would have been impossible, in the month at our disposal, 

 to overcome the physical obstacles of fog, snow, rain and 

 storm, and accomplish the object of the trip. We found the 

 sections published in the Geology of Newfoundland to be es- 

 sentially correct, and were so fortunate as to establish the 

 stratigraphic succession from the Middle Cambrian down 

 through the Lower Cambrian and Upper Algonkian to the 

 Signal Hill sandstone of the Avalon series of the Algonkian. 

 Mr. Howley studied certain problems in which he was interested, 

 while I investigated the problems connected with the Cambrian 

 succession of strata and faunas. 



Description of Sections, 

 northwest side of trinity bay. 

 Smith Sound Section. — On the northern shore of Smith 

 Sound, east and west of Smith Point, the Cambrian rocks are 

 well exposed along the shore. At Broad Cove, west of the 

 point, the transition beds between the Upper Cambrian (Olenian) 

 and the Middle Cambrian (Paradoxidian) are concealed by the 

 drift at the head of the cove. West of the cove the fissile and 

 arenaceous shales of the Upper Cambrian are well exposed and 

 contain Olenus. On the eastern side of Broad Cove the Middle 

 Cambrian is exposed. The measured section begins with the 

 dark argillaceous shales, and is as follows :
