ceous and other rucks, with gneisses and crystalline limestone, the whole 

 somewhat closely related to the precediug but regarded as forming an un- 

 derlying series of probably Huronian age. These constituted the metamor- 

 phic ridgea of the Sutton mountain range and its extension northeastward 

 to and beyond the Chaudiere river. The views thus presented by Dr. 

 Selwyn wire stated, with some slight modification, in several subsequent 

 papers. 



Tfu Gaspe" Studies. — In l ss '_' the survey of the Gaspe* peninsula showed 

 clearly the pre-, nee of an underlying series of crystalline schists, hornblen- 

 dic and chloritic, with epidotic and other rocks, which formed a large part 

 of the Shick-shock mountains and which evidently represented the eastward 

 prolongation of those just described. These were flanked on the south Bide 

 for the greater part of their extent by Silurian strata, hut on the north, be- 

 tween the mountain range and the St. Lawrence, a considerable thickness 

 of green and dark gray slates, in places Bchistose, occurred ; while the area 

 between these and the river was occupied by the red ami green slates, with 

 the sandstones and occasional conglomerates of the original Sillery and 

 Lauzon divisions. These rocks extend continuously from Le'vis to Cape 

 Rosier, near the eastern extremity of the Gaspe peninsula, and are exceed- 

 ingly uniform in character throughout. At very rare intervals an overlying 

 outcrop (1 f fossiliferous Levis shales is found. 



Towards the lower part of the St. Lawrence these rock- are underlain by 

 black shales and Limestone, often highly bituminous, and iu places by a 

 gray sandstone, the whole containing graptolites and other fossils of Bud- 

 son River and Trenton-Utica age. Their apparent underlying position is 

 doubtless due to a line of fault, the continuation of that Been on the north 

 side of the island of < Orleans and the course of which, in it- extension down 

 the river, was described by Sir William Logan in the earlier reports of the 

 survey. From certain peculiarities of structure at that time observed, it was 

 thought that the true position of the Sillery might really he the reverse of 

 what had bo long been maintained, and that it should form a Lower Btrati- 

 graphical series than the Levis, thougb the work necessary i" t he final estab- 

 lishment of ihi- point was lor the time deferred.

Work in iIk Eastern Townships. — In 1885 the detailed examination of the 

 k- of the Eastern Township- was begun by the writer. Commencing at 

 Sherbrooke, tin- work extended on the we-i to Richmond and on the east to 

 the boundaries of Maine and New Hampshire. The results of the two years 

 survey of this section appeared in the annual volume of the Geological 

 Survey Reports for 1886, accompanied by a map of the southeastern part of
