192 Notes on the Coal Field oj Pictou, 



seam is one mass of Cypris shells ; No. 2 contains principally 

 small ganoid scales; No. 3 seam has small fish jaws and small 

 Lepidodendron and Poacites on the roof. 



The sandstone bands contain Calamites, and large roots of Stiff- 

 onaria with their accompanying rootlets. Here the inch seam of 

 coal appears below the bands of bituminous shale succeeded by 

 the JJnio shells, unless fault has caused the outcrop of these 

 bands to be repeated. 



Ascending the East river and to the south of Smelt Brook, is a 

 thick band of coarse sandstone full of hard flattened red concre- 

 tionary balls and ripple marked ; then comes a four inch band, 

 of honey-combed, concretionary limestone, in which I have 

 detected a piece of shell in the fresh fracture, and which 

 looks like the metamorphic rock near Churchville. . I could not 

 find any fossils in the pit sunk at Sinclair's cove. 



The adits driven in upon the coal to the south of New Glas- 

 gow, by the side of the road to Antigonish, are upon the anti- 

 clinal axis ; both mines have the same fish remains in the roof 

 and limestone pavement, and cannot be worked far to the north- 

 west before they will be cut off by the conglomerate. The fish 

 teeth are abundant in the roof. In one slab four by six inches, 

 I counted fifteen large Diplodus teeth. Higher up the brook and 

 road, I am told, the crop of the coal shows a dip to the N. W., 

 but I have not vet seen it. 



The shales and coal up the McLellan Brook, dip from E. by 

 the bridge at George Eraser's farm, to S. 15° E. at Turnbull's farm, 

 then the measures are reversed, and at A. Patrick's adit, they dip 

 N. 45° E. 30^; where the oil shales have been worked for about 

 100 feet, and having struck a fault have been cut oft' by the 

 other shales dipping S. 20° E. 25^. Mr. Patrick has proved a seam 

 of bituminous coal about three feet thick, dipping to the N. E. 

 underlying his oil shales near the foot of the mill dam, in addi- 

 tion to the small seam which shows in the bank of the mill pond. 

 I am told that the high conical hill just verging to the south^ 

 contains iron ore, and that it is succeeded by limestone. 



[Among the fossils sent by Mr. Poole, the most interesting are 

 the following : 



Of placoid fishes there are, 1. Diplodus penetrans, N. S. This 

 is smaller than the species D. acinaces, found commonly in the 

 upper part of the Albion Main Seam, and described by me in a 

 supplementary chapter to my Acadian Geology, now in presa
