NOVA SCOTIAN GEOLOGY — HONEYMAN. 257 



McLclIan's Brook, they are of same age. The rocks at Malignant 

 Cove are Lower Carboniferous, conglomerates with intrusive Trap. 

 Laurentian lies east of Cove. Vide sections in " Geology of Anti- 

 gonish Co." Trans. 1874—5. 



V. — Devonian. Iron ore with Fossils. Nictaux Granites, 

 Nos. 781, 804. 



The Fossils in the iron ores of Nictaux are considered by Mr. 

 Selwyn, Dr. Dawson, Prof. Hartt and others, to be of lower Devo- 

 nian age. In fact the rockd containing these ores are at present 

 regarded as the only unquestioned representatives of the Devonian 

 Formation in Nova Scotia. 



The relation of the Granites, occurring at Nictaux, to the sup- 

 posed Devonian Formation is considered as demonstrating the 

 Upper Devonian age of the former, and also of the Granites asso- 

 ciated with the Gold Fields of Nova Scotia. Accordingly speci- 

 mens of these granites were arranged in this division of the collection. 



VI. — Carboniferous. Lower Carboniferous, 805 to 821. Mill 

 stone Grit and Coal Measures, 225 to 839. Upper Coal Measures, 

 840 to 843. 



This extensive, interesting and beautifully prepared collection, 

 with the exception of the first 138 specimens, has been presented 

 to the Smithsonian Institute at Washington. A geological map 

 of the Lower Provinces, coloured by Mr. Ells, of the Survey, under 

 the direction of Mr. Selwyn, was also exhibited, showing the sup- 

 posed course of the Laui'entian axis from Cape North, through 

 Cape Breton, through Arisaig, N. S., Pictou, and the Cobequid 

 Mountains, and through New Brunswick ; also the supposed 

 Devonian Granitic axis from Cape Canso through Guysboro' Co., 

 Halifax Co., Lunenburg, and Shelburne, Annapolis, &c 



Photographs. 

 There were also exhibited 21 beautiful photographs from well- 

 selected positions, illustrating the geology of the "Upper Arisaig 

 Series " and the succeeding Lower Carboniferous Formation, as ex- 

 posed in sections on the shore on either side of the Antigonish and 

 Pictou County line, i. e. from Doctor's Brook to Mill Brook. These
