194 HONEYMAN ON THE GEOLOGY OF NOVA SCOTIA. 



crops of marble. After this reconnaissance I commenced a regular 

 examination with the assistance of Messrs. Bell and McQuarrie, 

 starting about a mile to the east of the parts already mentioned. 

 On the shore of the Bras d'Or we found the beginning of the red 

 syenite of our former outcrop. Passing along westward we met a 

 series of outcrops of red syenite, and at last reached the summit of 

 a syenitic (George's) Mountain, having an elevation of 890 feet, 

 according to the measurement of Capt. Bayfield. Descending the 

 mountain we reached our first noticed outcrop of syenite. There 

 we found the syenite and serpentine already referred to in all but 

 immediate contact. Passing the excavations we mounted to the 

 summit, and found blueish-colored marble, rising iu lofty and pre- 

 cipitous walls. Proceeding onward we found the marbles parted 

 by bands of jaspideous rock ; then followed beautiful serpentinous 

 marbles and others. Our course was thus chiefly on the southern 

 side of the mountain range. Wishing to ascertain whether the 

 marbles and syenite were arranged as bands, we examined the 

 opposite or northern side of the range, a distance of 6 miles, and 

 observed continuous outcrops of red syenite, the limit of our exami- 

 nation being the second highest mountain of the range, having an 

 elevation of 700 feet. (Bayfield.) Ee-examining the mountain 

 outcrops we found jutting out boldly between red syenite outcrops, 

 diorite, similar to that at Arisaig. I had here another evidence of 

 identity with the series of Arisaig. Subsequently ire passed through 

 the mountain range in rear of the marble, and after passing over 

 outcrops of red syenite, probably a distance of a quarter of a mile, 

 we reached the rear of the marble massive walls of beautiful ophio- 

 calcite — serpentinous limestone. On the banks of George's River 

 we find outcropping, thick beds of limestone having a lower carbon- 

 iferous aspect. 



In order to shew the relation of these to the metamorphic rocks 

 already described, we have the aid of an excellent section of rocks 

 on the shore of the Bras d'Or, having the syenite already noticed 

 for its geological centre. 



Beginning at the mouth of George's River, north side, we first 

 exposed strata of limestone having a low dip. These are evidently 

 lower carboniferous ; they have abundance of small fossils chiefly
