miles asunder in a direct line. The northern one is traceable for seven 

 miles, from the vicinity of Cape Haldimand to the inner basin at Gaspe ; 

 which it crosses about 350 yards south-west of the Narrows at the entrance. 

 It brings to the surface, on the north side of the basin, some beds of 

 sandstone, which are rendered calcareous by an abundance of fossils. 

 The beds to the north-east of these, along the south-west side of Gaspe 

 Harbor and Bay, as already indicated, are upwards of 4000 feet higher in 

 the series. They contain a few inters tratified bands of a red color near the 

 top, some of them with casts of shrinkage cracks : and along the strike, 

 between Pointe Lourde and Cape Haldimand, some of the best character- 

 ized specimens of the land plants of the formation are to be obtained. 

 In the upper 760 feet, eight beds are seen to be marked by the vertical 

 rootlets of Psilophyton : and on one of these, two hundred of the rootlets 

 were counted in a square of six inches. 



The mark which has been taken as indicating the direction of the 

 southern anticlinal axis, is the course of the greenstone dyke in its 

 vicinity ; this, however, has as yet been traced only a short distance, as 

 it soon becomes covered up, after striking into the forest. It is probable 

 that this dyke is connected with a dislocation, throwing down the measures 

 to the north-eastward. It is not easy, however, to say how much higher 

 in the series the beds on that side may be, than those on the south-west. 

 The latter are, as has already been stated, at the base of the 7036 feet of 

 strata given in the vertical section ; while on the north-east side, between 

 Tar Point and Douglastown, a section of 3800 feet was observed, after 

 which the summit of the series became concealed. At about 500 feet 

 from the base of this section, there are met with the remains of a conifer- 

 ous tree, described by Dr. Dawson under the name of Frototaxites Logani, 

 The stem of one of these, obtained by Dr. Dawson, must have been 

 twelve inches in diameter, before it became compressed. About 600 feet 

 still higher among these strata, several surfaces in succession are marked 

 by serpentining impressions, about an inch wide, deeply grooved into the 

 stone, marked by small parallel transverse furrows, which are about a 

 quarter of an inch apart. These are perhaps worm-tracks, and are asso- 

 ciated with a few bivalve shells of the genus Rensselceria, probably 

 R. ovoides. All of these strata, and most of those above them, in which 

 sandstone greatly predominates over shale, are in general drab-colored, 

 though some are grey. Many of the surfaces are marked by carbonized 

 comminuted plants, similar to those which have already been mentioned ; 

 and argillaceous iron ore occurs in nodules in several beds, about the 

 middle of the mass. 



The dips on the north-east side of both of these anticlinal flexures are
