OF THE PENINSULA OF GASPE. 183 



and about the neighbourhood of Conception Bay — very probably 

 the whole island — is rising out of the ocean, at a rate which 

 promises at no very distant day, materially to affect, if not to 

 render useless, many of the best harbors we have on the coast. 

 At Port de Grave a series of observations have been made, which 

 undeniably prove the rapid displacement of the sea level in the 

 vicinity. Several large flat rocks, over which schooners might 

 pass some thirty or forty years ago with the greatest facility, are 

 now approaching the surface, the water being scarcely navigable 

 for a skiff."

Art. XV. — On the Hocks of the Quebec Group at Point Levis; 

 by Sir William Logan, F.R.S.; Director of the Geological 

 Survey of Canada ; in a letter addressed to M. Barrande. 



Montreal, 15th March, 1863. 



My Dear Mr. Barrande, — Mr. Jules Mareou has addressed to 

 you a letter dated the 2nd August last, on the Taconic rocks of Ver- 

 mont and Canada, in which he says, on page 10, " I was able this 

 " year to follow out and trace every bed and layer on the whole 

 ■■" contour of Point Levis, from the Grand Trunk Terminus to In- 

 5< dian Cove; and as Point Levis is a point of land surrounded 

 " by high cliffs, I feel satisfied that there is no repetition of beds, 

 " and no synclinal axis ; and that the few foldings of the strata 

 4i at Ferry's cliff are mere accident, confined to a distance of a few 

 " feet, and are without any effect upon the whole mass of strata 

 **' but are what we call in French structure ployee (contorted 

 "" strata)." On page 14 he says : "Fearing that my first unsuc- 

 " cessful attempt last year to understand the explanation of Messrs. 

 u Logan and Billings might be my own fault, I tried very hard 

 ■** this year again, when at Point Levis, but with no better success 

 <£ and I left the Point fully convinced that the fossils described by 

 "Mr. Billings, and the so-called outcrops, A 2 , A 3 , A 4 , &c, of 

 " Mr. Logan, were collected and observed in a very careless way, 

 " without regard to stratigraphy, by irresponsible collectors, or 

 " by unskilful practical geologists." 



I have neither time nor inclination for controversial geology. I 

 have never criticised any of Mr. Marcou's remarks on rocks in 

 Canada, or out of it, nor have I suggested any such criticisms to 

 ■others ; but a charge of carelessness on the part of public officers
