HONEYIMAN — ON NOVA SCOTIAN GEOLOGY. 17 



brook i, e. where the east branch unites with the main branch, 

 near a lower carboniferous brine spring. Returning to the start- 

 ing point at McDougalPs mountain and proceeding eastward, we 

 pass over the east branch of Doctor's Brook, and climb Mackintosh's 

 moui#tain — we find diorite as the lowest rock with overlying argil- 

 lites ; these in the direction of their dip or northerly extend for some 

 distance onward to the shore, forming mountains. To the S. E. 

 of Mackintosh's and McDougalFs rises McNeil's mountain, having 

 according to Bayfield an elevation of 1010 feet above the sea 

 level, being by ten feet the highest mountain of the range. This 

 mountain consists of red syenite which rises abruptly on the south 

 side, with a marsh and wilderness without any appearance of rock 

 in the rear. The crown of the mountain is entirely syenite as 

 well as its sides, in the cultivated land that rises up against it, and 

 on the road leading to it we have as before, a succession of argillite 

 extending northward to a certain point. We shall leave it there 

 with the expectation of meeting it again. 



I commence at the said point at McDougall's mountain again. 

 I pass from the Oneida conglomerate in a northerly direction 

 across the strata and towards the shore. I think I can separate 

 the series into different members, but the operation is somewhat 

 uncertain owing to the absence of fossils. My progress is arrested. 

 The sides of the rock are precipitous, the ravine is of great depth ; 

 it extends east and west. From Doctor's Brook east to Doctor's 

 Brook west it forms a valley for Arisaig Brook and east branch 

 Mill Brook. It is filled with sapling bushes, marshes, &c. It is 

 the highway for our old acquaintance bruin. The wool and bones 

 of sheep show that he improves his opportunities. 



On the south side of the ravine are lofty rocks — diorite — - 

 succeeded by a broad band of red slate, the exact counterpart of the 

 supposed Devonian slate of Lochaber. This broad band extends 

 to the insulated carboniferous patch already referred to at East 

 Branch, Doctor's Brook, and its small tributary en the north which 

 extends to the vicinity of the fossiliferous band ; it extends westerly 

 and terminates on the south side of the east branch of Mill Brook 

 almost due south of the mouth of McAra's Brook. Here the lower 

 carboniferous sandstones also rest on it unconformably as on the
