include with them the grass-green shale of Shiphead, with Dalmanites 

 dolbeli at the top of Logan's division 7 and from the base of these to 

 the base of the chert beds on Shiphead is about 300 feet. Above are 75 to 

 100 feet of chert-bearing rocks on which the lighthouse stands, making an 

 approximate total of 400 sh,ph«d ^^^ c«p.c«pe- 



feet. The beds of our 

 division 3, if ever present 

 at the cape, have been 

 sheared away.

 division are gray-blue lime-

where they are overlain by the Gaspe sandstones. They contain pretty 

 much the same fauna as the beds immediately beneath, though Chonetes 

 m e 1 o n i c u s has, in a single instance only, been met with at any other 

 horizon. Logan has Regarded the contact of limestone and sandstone at 

 Little Gaspe an unconformity and in this case these beds may not represent 

 the true summit of the series as they are absent from Grande Greve to 

 Shiphead, but it is quite likely that their absence is due to shearing away. 

 They are apparently about 50 feet thick. 



Our estimate of the probable thickness of these strata, 550 feet, falls 

 notably below that of Logan, 800 feet, but in our judgment some portion 

 of the series has been lost at the top and it is quite possible that the 

 original thickness fully equaled that ascribed to it by Logan. 



Dtp. The inclination of the limestones on the Forillon is practically 

 uniform and the lower beds are conformable herein with the upper. The 

 degree and direction of dip was given by Logan as southwest < 24°. 

 This dip is qualified by local displacements of slight extent along joint 

 faces entering the cliffs at large angles to the strike and along these lines 

 are veins of calcite and barite mingled with a fault breccia and carrying
