EARLY DEVOXIC HISTORY OF NEW YORK AND EASTERN NORTH AMERICA 8 1 



8 Drab massive sandstones, which in the lower part are clouded or 

 mottled with a reddish tinge, and at the bottom exhibit an interstratifi- 

 cation with red shales ; at the summit the beds are inclined to gray. In 

 many parts, they hold scattered pebbles of white and greenish quartz, 

 and blood-red jasper, with some of limestone ; but the pebbles never 

 become so numerous as to constitute a conglomerate. On the surfaces 

 of many of the strata, and in the oblique elementary layers or false bed- 

 ding of some of them, there occur carbonized comminuted remains of 

 plants ; wiiich are too imperfect to be determined . . . . 663 feet 



7036 feet 



i-iTTijE, fiig lower portions of this great series of sandstones are met with in Little 



COVE Gaspe Cove; where in addition to the various species of fossil plants already 



mentioned, are found the remains of what appears to be a species of Calamites ; 



one specimen of which shows a flattened stem 4 feet long, with a breadth of 4 



OASPK inches. The inferior portion of the formation skirts the northeastward side of 

 **'*-*^ Gaspe bay, and the northwest arm, from the cove, as far as the north branch of 

 Dartmouth river ; where it occupies a breadth of about 9000 feet, across the meas- 

 ures ; giving, at an average dip of 26°, a thickness of about 4000 feet. On the 

 southwest side of Gasp^ bay, in the neighborhood of Gaspe basin, the same strata 

 rise with an opposite and more precipitous slope, forming a trough under the bay. 

 The tiiickness there exposed is again about 4000 feet. The same beds next fold 

 over an anticlinal axis, which conies out upon the bay near Cape Haldimand ; 

 then, dipping at a very moderate angle on the southwest side of the axis, beneath 

 the lagoon at the mouth of the river St John, they reappear, with a nearly opposite 

 slope, at the southeastern end of Douglastown village ; and exactly face Great 

 Cape Oiseau (Cap Brule of Bayfield's chart) and Little Gaspe on the northeast 

 side of the bay. Following the coast, they exhibit a slight sinuosity in Seal cove 

 poiN'T(Hrehaut bay of Bayfield) ; and at the extremity of Tar ])oint, between this cove 

 and the next one farther on, they fold over another anticlinal axis ; the position 

 of which is indicated l)y a remarkable greenstone dyke, holding petroleum. The 

 direction of both of these anticlinals is nearly northwest and southeast. 



It is from this i)oint to the termination of the series, in the cove immediately 

 northward of Pointe Jaune or Yellow Head, that the strata given in the vertical 

 section are found. The coast cuts them obliquely ; and in every step southeast- 



LONG ward from Tar point, higher strata are met with, in advancing, until Long cove is 

 reached, where the red sandstones are seen. In this cove, the measures have a 

 very moderate inclination, and a slight protrusion in the line of strike causes the 

 coast section of the cliff to present a gentle arch in the center, repeating a part of 

 the beds. Farther on, the section still gains upon the strata, in the vicinity of 

 Red Head, and beyond it ; until they are suddenly cut off by a fault, at the spot 

 already indicated as the termination of the series. Throughout the whole dis- 

 tance, the strata are seldom concealed ; and though several small faults occur, the 

 allowance that is to be made for them, may be seen in the cliff, which is generally 



ANTi- bold. 



CLiNALS -j'l^g j^^.Q anticlinals which have been mentioned, appear to run parallel, as well 

 to the mountain ranges of the neighborhood, as to the calcareous rocks on the 

 northeast side of Gaspe bay. They may be about 3 miles asunder in a direct line. 

 Tiie northern one is traceable for 7 miles, from the vicinity of Cape Haldimand to 

 the inner basin at Gaspe ; which it crosses about 350 yards southwest of the Nar- 

 rows 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.
