10 nONEYMAN — ON NOYA SCOTIAN GEOLOGY. 



found the so-called Marble Mountain, which has lately been brought 

 into prominent notice by the enterprise of Mr. Brown. I visited 

 Grand River, and found lower carboniferous limestones and a bed 

 of wad or bog manganese, which had been supposed to be coal. 

 I crossed over to Red Islands and collected a number of fossils. 

 The most remarkable of them is a recurved Conularia. At Big 

 Baddeck I found a mountain to consist of granite where I had 

 expected to find syenite or greenstone, which led me subsequently 

 to maintain that the Middle River or Wagamatcook auriferous 

 strata were of the same age as the Nova Scotian strata, or Lower 

 Silurian, and not Devonian as some Geologists maintained. I 

 found marble at the head of Whycocomagh Lake, and the little 

 carpolite shortly after described by Dr. Dawson in the Transactions 

 of the Geological Society as Trigonocarpum Hooheri. I found 

 this in a piece of sandstone on the shores of Port Hood. I 

 returned to Nova Scotia and was directed by the Commission to 

 give some attention to the Geology of the Gold Fields. I accord- 

 ingly made an examination of the undeveloped Waverley barrel 

 quartz. I examined the section of rocks on the Windsor and 

 Truro lines of Railway, but not having time to make a detailed 

 examination, my observations were necessarily crude. I commu- 

 nicated a paper on the subject to the Geological Society. In this 

 paper I maintained the same view in regard to the Lower Silurian 

 age of the gold fields as Dr. Dawson had done in his A.cadian 

 Geology. I may mention that in the discussion that took place 

 in the Society on the reading of that paper, there was a difference 

 of opinion expressed in regard to the age of the Gold Fields, 

 Sir W. Logan impugned my views, maintaining that the rocks were 

 Devonian. Sir Rodrick Murchison on the contrary, supported the 

 views that I maintained. I found subsequently that my observa- 

 tions were too hastily made to be altogether accurate. The descrip- 

 tion of the field itself seems accurate enough, and the succession of 

 the rocks between Lakelands and Windsor, but the order of rocks 

 from Lakelands to Waverley, and the supposed connection of the 

 rocks and the line with the Waverley Gold, Field, was altogether 

 imaginary.
