have construed the fauna correctly, the place of the Limekiln rocks is 

 between the south and north flanks of Joli or is a corresponding 

 portion in the series. We may find no clear evidence of the necessary 

 fault plane in that escarpment, but this cliff at the Limekiln is evi- 

 dently cut off by faults both therefrom and from the Cap Canon 

 mass. 



Cap Blanc massive. From Cap Canon southward for a distance 

 of 2 miles sweeps, first, the broad Robin fishing beach or South cove 

 buttressed at the south by horizontal or slightly dipping beds of red 

 sandstone and conglomerates rising into a constantly more elevated 

 sea wall till Cap Blanc is reached. Here as one turns the point of 

 the headland and rounds the light, vertical limestone strata are once 

 more exposed and their contrast in color to the horizontal or slightly 

 northeast dipping red strata which overlie them and abut against their 

 slopes, gives name to the place. The sea wall is sheer and the foot 

 of the cliff accessible with risk, even by water. 



The vertical thickness of these rocks measuring from the point of 

 the cape southward is estimated at 700 to 1000 feet. They are light 

 gray in general effect and the succession of the strata is obscurely 

 presented in the highway and field outcrops. With the slight inclina- 

 tion of the strata away from the vertical toward the north as seen 

 in the Mt Joli massive, we first find in t'. c highway cut ascending the 

 cliff from the north a red limestone, suggesting in tint the Perce

but principally and oftenest a large and heavy shelled pelecypod 

 having a broad cardinal plate extending inward from the hinge line, 

 not attached to the bottom of the valves nor thickened at its junction 

 therewith. This rock is of such character that it breaks in almost 

 any direction except along the surface of these fossils but one 

 example of this species has the valves together and this, sectioned 

 vertically shows these projecting plates not in apposition as though
