'UO THE PICTOU COAT. FIELD — POOLE. 



McLean's brook on Sutlierland's i-iver is full of excellent ore, 

 some of the pieces being- large, six inches in diameter. 



Limestone. — On the top of Eraser's mountain, immediately 

 over the New Glasgow conglomerate, are beds massive but aren- 

 aceous that were worked half a century ago. They are overlaid 

 by the botryoidal bed that is so characteristic of this horizon* 

 and higher in the series by the 4 inch band of agglomerate seen 

 just above the mouth of Smelt brook. Nodules of limestone 

 occur in the sandstones under the cemetery on the bank of the 

 East river, and also in Eraser Ogg's quarry. The coal measures 

 and the rocks of the Millstone Grit are seldom calcareous, an ex- 

 ception being the pavement of the George McKay seam. The 

 Lower Carboniferous carries many interbedded and massive beds 

 occasionally shewing obscure fossils, and the Devonian of 

 Waters' hill also exposes a large deposit. 



Gypsum. — Is found at several spots on Waters' hill, on 

 McLean's brook, and near the church at the base of Green hill. 



Chalcocite a,nd Malacliite are associated with lignite in the 

 Permian sandstones. 



Oil Coal. — The curled shale lying below the McGregor seam 

 were at first thus so-called. Then it was named Stellar coal 

 bv Mr. H. Poole, and subsequently on analyses Stellarite b}^ Pro- 

 fessor How. Richer portions gave 11,000 cublic feet of 36 candle 

 gas, and picked samples yielded up to 190 gallons of crude oil to 

 the ton. The return of one cargo sent to Boston was 54 gallons 

 and the value put at $8.75 per ton. At the same time Albertite 

 from New Brunswick yielding 87 gallons sold at ii5l5.00, and 

 Boghead coal from Scotland, giving 125 gallons, at $14.00 per 

 ton. The shale associated with the " bat" and generally shipped 

 with it gave about 44 gallons to the ton. It may here be noted 

 that the colliers working it were paid ()s. per 22 (long) cwt. and 

 8ii. extra for close side in long wall work. 



Oil coal was also worked on McLellan's brook and west of 

 Blackwood's mill dam. 



Oil Shale. — In 1859 and 1800, before the development of the 

 oil wells of Pennsylvania, there was a very active search for oil- 

 producing shales. Bands were found at Deacon's cove mill dam
