356 GEOLOGICAL GLEANINGS—HONEYMAN. 
DiIoRITE MOUNTAIN. 
This is the last of a short range of mountains that extend 
from Loch Ban in a northerly direction. We have already 
directed attention to the southern extremity of this Lower Car- 
boniferous range, on which we found Archzean boulders. We 
now enter on the middle of the range from the Broad Cove road 
and at the northern end of the Sandy Hills (moraine). We find 
Archzean boulders on our way. We cross the moraine and ascend 
the mountains. We find a boulder or two, and then they disap- 
pear. We proceed along the mountains, northward, observing 
outcrops of chocolate sandstones, and come to Diorite Mountain. 
This is a very interesting mountain. The exposures on its sides 
and the outcrops on its summit reveal the character of the rocks. 
They are of the same constitution as those of Arisaig and East 
River, associated with the Lower Carboniferous formation. Like 
the Arisaig igneous diorite they are compact, amyedaloidal, por- 
phyritic and vesicular. We collected specimens of compact rock 
and porphyrites on the highest outcrop.*
