run as the stratified masses. Serpentines were found to be 
largely developed in different regions, among which may 
be mentioned the west coast from Port-a-Port Bay north- 
ward more than half the distance to the Strait of Belle Isle, 
around Hare Bay near the northern extremity, Notre-Dame 
_ Bay and the head waters of the main Gander River. 
The Cambrian and Lower Silurian formations are so 
well displayed and so rich in fossils that Mr. Howley 
thinks among them will be found the solution of certain 
problems in the geology of eastern north America. He 
is of opinion that the serpentines form two distinct groups, 
one belonging to the Cambrian or Silurian and the other 
to the crystalline series. 
Before any Cambrian fossils had been discovered in New- 
foundland, Mr. Murray, was led to believe, from other con- 
siderations, that certain rocks in the eastern part of the 
island belonged to that system and after much search he 
found a few at Bell Island and around Trinity Bay, which 
were described by Mr. Billings in his Paleozoic Fossils, 
Vol., If. Part I, and in the Canadian Naturalist, new series 
Vol. VI, July, 1872. In the summer of 1874, Sir Wm. 
Logan sent Mr. T. C. Weston, a lynx-eyed collector on the 
Canadian survey, to find more fossils among these rocks. 
He discovered them in abundance in the banks and ona 
small island in Manuel’s River and also at Bell Island and 
Topsail Head, all in Conception Bay. These localities have 
since been visited by Prof. C. D. Walcott and described in 
his “Correlation Papers-Cambrian,” which constitutes 
Bulletin 81 of the U.S. Geological Survey. 
The original work that Mr. Murray performed in New- 
foundland during the twenty years which he devoted to it 
were of more service in making the island favourably 
known to the outside world than anything which had pre- 
viously occurred. ‘The economic results of the Geological 
Survey have been very important. Before it was com- 
menced the interior of the island was unknown, even geo- 
graphically, and the great value of its mineral, timber and 
agricultural resources was unsuspected, The fisheries were .
