creek. These rocks, judging from the fossils contained, be- 

 long to the so called " silurian group. 



The greywacke and slates of this group also appear on the 

 coast of the Bay of Fundy, between Great Salmon river, and 

 Salisbury Cove, accompanied by soft argillaceous limestone 

 and serpentine, but wherever they have been found in this 

 part of the province are injected with dikes of trappean 

 rocks, and have suffered much from volcanic causes. 



We now proceed to take a cursory view of the coal dis- 

 tricts of that division of the province, to which the second 

 report more immediately refers. The first of these was ob- 

 served to embrace the whole of capes Meranquin and En- 

 rage ; but these are small portions of the Cumberland coal- 

 field in Nova-Scotia, and at present require no further 

 consideration. Commencing at Shediac, the coal-field 

 of the county of Westmoreland extends along the east- 

 ern shore as far as Tedish river, then running along 

 an irregular line southward it approaches the villages 

 of Sackville and meets the new Red Sandstone near 

 Dorchester islands ; a line drawn from " Shediac to the Pe- 

 titcodiac, about 10 miles below the Bend,'^ will mark its 

 northern side. This tract of country embraces that part of the 

 coal-field which is situated on the east side of the Pettico- 

 diac, except a small group of strata, observed near the road 

 leading from Bay Verte to Sackville. The coal-field then 

 becomes more narrow, and crossing the river, maintains an 

 average breadth of ten miles westward, until it reaches Sus- 

 sex vale ; here its extremity is forked ; one branch is curved 

 towards the north-west, until it meets the source of Stud- 

 holm's millstream, the other becomes very narrow and dis- 

 appears beneath the conglomerate, a few miles westward 

 and southward of Sussex church. About eight miles north 

 of Shepody the coal strata meet the syenite, and cross the 

 sources of Turtle creek, and Coverdale river ; at the head of
