74 GLACIAL GEOLOGY OF NOVA SCOTIA—HONEYMAN, 
the shore at the east side of the Head. Judge James had also 
found a fine specimen in the preceding year. These abound in 
veins, in the traps of Blomidon. Still the question was asked: 
How did the boulders, ete.,come to the bluff? Massive boulders 
of quartzite lay at the foot of the bluff and partly embedded in 
it. These were striated and grooved ina singular manner. We 
were thus referred to Point Pleasant, Halifax, especially the well 
known and wonderfully striated and grooved rocke moutonneé at 
Prince of Wales Tower. Vide. Picture in Sir C. Wyville Thom- 
son’s Challenger Expedition Volumes. Procuring the Admiralty 
“Chart of the Coast of North America from the Strait of Belle- 
Isle to Boston,” I located on it our glaciated rock surface. On 
extending the lines or courses 8. 20 E., N. 20 W. and S. 30 E. 
and N. 30 W. magnetic, northerly, they were seen to pass by 
Blomidon and over it. Several ruts on the same surface dis- 
tinctly show that the agency that formed them had moved in a 
southerly direction. All this seemed very satisfactory. An 
important problem thus presented itself for solution. As the 
occurrence of the Triassic amygdaloid rocks was limited in an 
easterly direction to Five Islands on the north side of the Basin 
Minas, it was considered that a parallel (S. 20 E.) drawn from 
Five Islands to the Atiantic Coast would limit the occurrence of 
the boulders on the shore. There were still other boulders 
observed occurring in abundance associated with the amygda- 
loids on the shore and in the bluff. These are syenitic gneisses, 
syenites, hornblendic granites, diorites, &¢. They were at once 
recognized as of Archean rocks, whose nearest seat is the 
Cobequid Mountains. Through these our Blomidon striation line 
would also pass. 
I found, after a course of investigation extending over many 
years, that Osborne Head is one of a series of heads and less 
elevated deposits which extend from Thrum Cap, in the mouth 
of Halifax Harbour, to Three Fathom Harbour, a distance of 16 
miles, Vide. Chart. In this “Terminal Series” I have found 
represented by boulders, not merely the Triassic Igneous rocks of 
Blomidon and the Archzean Metamorphic of the Cobequid 
Mountains, but also Silurian fossiliferous rocks and Carboniferous,
