116 E. W. ELLS ON THE GEOLOGY OP 



Sillery, below Quebec, on the Beaumont shore, certain strata interstratified with the red 

 and green slates, also afforded the writer, in 1888, phyllograptus, showing the extension 

 downward of this form at least. In the same formation also, but from a somewhat lower 

 portion, seen at St. Michel de Bellechasse, certain straight graptolites were found in the 

 same year, associated with obolella and fragments of dictyonemas in the associated black 

 shales. In connection with the pillar sandstone of Ste. Anne, thin beds of limestone 

 conglomerates were observed, in which respect they resemble the Sillery of Kamouraska 

 and other points west of River du Loup. 



The rocks about Ste Anne de Monts present certain peculiarities worth considering ; 

 for while the great bulk of these, as already stated, are of Sillery age, certain limited 

 areas, apparently closely infolded, as at Cape Rosier, yield Levis fossils, and other small 

 areas are of the same cherty black character, as beds found in the Trenton Utica and 

 already described. These newer rocks, both the Levis and the Trenton, are seen on the 

 beach at low water in a small cove about three miles west of the mouth of Ste. Anne 

 River, and the cherty beds are also well observed on a road running inland from a point 

 about three miles east of the river and about one mile from the shore where there is a hill 

 of the hard cherty rocks with dark grey ochrey weathering slates, and which apparently 

 represent the upper division of the coast series. 



The Ste. Anne de Monts river, which enters the St. Lawrence at this point, flows 

 northerly after skirting the base of the Shickshock range of mountains, and traverses the 

 intervening strata at nearly right angles to their strike, showing a succession of red, green 

 and black shales with hard sandstones for about ten miles, which is the distance between 

 the coast and the foot of the range. The range itself consists principally of crystalline 

 rocks, chloritic, hornblendic and epidotic, and rises abruptly to a height in some places of 

 4000 feet above sea level. On the southern side of the range a large development of ser- 

 pentine rock with diorite is seen, resting against black hornblende schists. These schists 

 undoubtedly belong to a period older than the Sillery, the lower part of which flanks the 

 hills on the north for many miles, while the south side is for the most part overlapped by 

 sedimentary rocks of the upper sihirian age. These mountains indicate the eastern 

 extremity of the Sutton mountain range of the Eastern Townships. 



The Ste. Anne locality is worthy of mention also from the fact, that this point and 

 the newly discoA'ered area at Cape Rosier represent the only, at present known, places on 

 the whole coast from which fossils of the Levis formation have yet been obtained cast of 

 the typical Levis beds, oppo.site the city of Quebec, and from this point westward, till 

 Point Levis is reached, the careful survey, not only of the entire coast line, but of every 

 line accessible inland to the overlap of the Silurian, has revealed no strata resembling the 

 Levis, or newer than the Sillery, except certain faulted-in limited areas of the Trentou- 

 Utica, to which reference has already been made. At several points along the coast the 

 Sillery rocks contain fossils. Occasionally these are found in the black and green shales, 

 but more frequently in certain beds of limestone conglomerate, which are associated with 

 hard qi^artzose sandstones, which, in turn, are interstratified masses in the red and green 

 shale series. When these are well developed they give rise to a rugged surface and 

 several parts of the shore section shows this character well. Among these may be men- 

 tioned Les Islets and G-rosses Roches, below Matane, where immense ledges of hard quartzose 

 grit and conglomerate jut out into the St. Lawrence, the composition of the latter being
