GLACIAL TRANSPORTATION—HONEYMAN. 4} 
are seen in their alternate retreat, advance and retreat, unloading 
their freight, raising drift accumulations, and obstructing or 
destroying the great highway so as to render it impossible for 
any like agency to accomplish similar work. This is the condi- 
tion in which we now find it, unless where the condition has 
been aggravated by the operations of agencies at work in post 
glacial times. 
HISTORY OF THE PROBLEM. 
In the summer of 1872, Judge (in Equity) JAMES showed 
me, in the Museum, a beautiful specimen of agate, which he 
found at Cow Bay. I recognized it at once as an agate from the 
Blomidon series of rocks, and said so. I thought no more about 
it. On the 24th of May the following year—the Queen’s birth- 
day—I went to Cow Bay with my late lamented friend—W. 8. 
StTrRruine, Esq., of Halifax, to spend a holiday. Wandering along 
the shore, ny attention was attracted to the amygdaloid boulders 
washed by the sea. I recognized them as Biomidon rocks. 
Their occurrence here was perplexing, until abundance of like 
boulders and a beautiful specimen of agate, were seen and col- 
lected ont of the lofty section of drift on the east side of the 
bay. Masses of quartzite, curiously furrowed, also fallen from 
the drift, suggested a connection with the striation of Point Plea- 
sant. An interesting problem in glacial transportation thus 
presented itself for solution. I forthwith commenced investiga- 
tions. JI communicated two papers to the Institute containing 
the results of these investigations. One was read in December, 
1875, and the other in March, 1876. At the request of my 
friend, Prof. Lestey, the substance of these was communicated 
to the American Philosophical Society in May 16, 1876. The 
Paper was illustrated by a sketch map, and an extensive suit of 
boulders, derived from the various formations over which the 
transporting agent had passed. This collection, of which there 
is a list in my paper read to the Institute “On Nova Scotian 
Geology at the Centennial Exhibition of Philadelphia, 1876,” 
was awarded a prize medal by the International Judges of Class 
I. Further investigations were recorded in my paper “On the
