V. Devonian. 



The areas of Devonian occurring in southern New Brunswick may 

 be stated as follows : — 



1. A large basin, or double synclinal, east of St. John Harbour, occu- Areas of 

 pying the valley of the Mispec, with a southern area extending north- oman ' 

 easterly across the Black Eiver, near the forks of the East Branch. 



2. Isolated outcrops on Coal Creek and on Canaan Eiver and North 

 Fork, presumably of this age, but lacking evidence of fossils. 



3. Small areas about St. John and Carleton, with possibly Partridge 

 Island. 



4. A small area about the eastern extremity of Spruce Lake, on the 

 St. Andrews railroad. 



5. A belt stretching west from Musquash Harbour to Lepreau 

 Harbour, in which is contained the so-called anthracite mine of Belas 

 Basin, with a smaller detached area along the shore from By Chance 

 Harbour to Dipper Harbour. 



5. A large area in the northern part of Charlotte county, embracing Typical area, 

 the former pale argillite series and extending into Queens county. 



Of these the first, or area east of St. John Harbour, may be styled 

 the typical Devonian of the province. Its division and characters are 

 stated in full in the report of 1870-71, the estimated thickness of the 

 four divisions being given at 7,500 feet. This formation has a particu- 

 larly rich fauna and flora, whose details have been very carefully 

 worked up, principally by the late Professor C. F. Hartt. The fossils 

 especially abound in the Dadoxylon sandstone and Cordaite slate, the 

 former containing, in addition to the plant remains, several crustaceans 

 and wings of insects. Many of the plant stems are graphitized, and at 

 Belas Basin, in Lepreau Harbour, a bed of graphitic anthracite has 

 been opened. 



West of the St. John Harbour, the principal surveys made on this Coast west of 

 formation, since the report of 1870-71, include the area extending from Harbour. 

 Musquash Harbour to Lepreau. On the coast west of Musquash the 

 rocks of this age are first observed about midway between Little Mus- 

 quash and By Chance Harbour, where purple and grey sandstones and 

 slates are seen skirting the eastern side of the harbour, dipping 

 S. 80° E. ■< 15°-20°, and resting unconformably upon the crystalline 

 limestones, syenite and felsite of the pre-Cambrian. From this point 

 they occupy the shore as far as the west side of Little Dipper Harbour, 

 being well developed about Chance Harbour. On the west side of
