IN NOVA SCOTIA FLETCHER. 325 



" Very nearly on the strike they are again met with on a 

 brook on the property of Mr. James Small, on the road to Little 

 Harbour, Merigomish. The one locality is as much as three 

 miles from the other ; but the botryoidal concretionary limestone 

 layers in both are so peculiar and so strikingly like in appear- 

 ance, and in their relation to any overlying seam of coal, that 

 no doubt can be entertained of their equivalence ; and I have no 

 evidence yet to shew that the mass is here of less volume than 

 farther to the west." 



Another exposure of these rocks, 1,372 feet in thickness, 

 occurs at Alrna mills bridge on the Middle River, beyond which 

 they reappear in Rogers Hill and Mount DaJhousie at the 

 eastern end of the Cobequid range, also at the head of River 

 John, and in considerable thickness on Waugh River. To the 

 eastward, they have been followed through Quarry and Olding 

 Islands to the Big Island of Merigomish.

In tracing them west from New Glasgow to the Middle 

 Eiver, they appear along the northern flank of Waters Hill to 

 directly overlie the altered Devonian rocks of that locality. 

 Exposures would seem to give direct proof of the unconformity 

 of the conglomerate with the rocks of the Millstone Grit, which 

 unconformity we should naturally have expected from the pre- 

 sence of pebbles derived from rocks of the latter division in the 

 former. 1 



Of these rocks Gesner wrote thus in 1836 : 2 " The red sand- 

 stone * * * covering the great coal basin of Pictou * * * 

 is often associated with beds of conglomerate * * * these 

 towards the surface seem to pass insensibly into a red soft sand- 

 stone, which from its ready disintegration yields a rich and 

 fertile soil." At the same time, however, he correlates the 

 Mountain Limestone with the Permian of Caribou Harbour and 

 Pictou Island ; while certain fossils of that limestone at Economy 

 and Merio-omish he calls Belemnites and Ammonites.
