DAWSON AND HINDE 



there may be repetitious by faults or folding. The sandstones and shales of Lighthousts 

 Point contain Retiolites ensifonnis^ of Hall, many trails of worms, and worm castings of 

 the type of ArenicoHles spiralis. The sandstones of Monnt Misery contain fragments of 

 Relioliles eiisiformis. The shales on the south side of the bay, presumably near the upper 

 part of the series exposed, contain the sponges in question, a species of Linnarssouia not 

 distinguishable externally from OboleUa pretiosa of Billings, and the slender branching 

 fucoid which I have described as Bui/iotrephis pergradlis. ^

Note.— The series from the Church to Mt. Misery is probably descending and conformable; but the sandstones forming 

 the cliif near McNider's Brook to the eastward, are not improbably those of Mt. Misery thrown to the southward by a fault, 

 and not as would .ippear from the map a continuation of those near the Church, which probably pass inland of them. 



In the conglomerates are limestone boulders, holding fragments of Trilobites of the 

 genus Solenopleura and other fossils ; but these seem to be of Lower Cambrian age, or 

 considerably older than the beds in which they occur. 



There can be no doubt, from the stratigraphical position of these beds, that they 

 belong to the Quebec group of Sir W. E. Logan. This is, however, now known to 

 include, on the Lower St. Lawrence, beds ranging from the Calciferous (Tremadoc) to the 

 Trenton (Bala), and the beds are so much plicated that it is often difficult to unravel their 

 complexities of arrangement. At Metis, the evidence of the pebbles in the conglomerates 

 indicates that they are newer than the Lower Cambrian, and the few fossils found in the 

 sandstones and shales would tend to place them at or near the base of the Levis division, 

 or approximately on the horizon of the Chazy, equivalent to the English Arenig. 

 Lapworth, in his paper on " Canadian G-raptolites," ' suggests that the sandstones holding 

 Eetiolites may be older than this ; but hitherto we have not found at Metis the charac-
