VIIL—Some Nova Scorran ILLUSTRATIONS OF DYNAMICAL 
Grotocy:—By Pror. L. W. Battery, Pa. Dynes 
University of New Brunswick. 
(Read 9th March, 1896.) 
The following notes and accompanying photogravure plates 
are designed to present to students of the geology of Nova 
Seotia a few phenomena and results which seem to the writer 
sufficiently remarkable to deserve some special notice. The 
notes and pictures were all taken in connection with the work 
of the Geological Survey of Canada, and are reproduced here 
by the kind permission of the Director. 
I. SAND HILLS OR DUNES OF THE SOUTHERN COAST. 
At several points along the shores of Queen’s and Shelburne 
Counties the attention of the traveller is attracted, even in mid- 
summer, by what appear, in the distance, to be great drifts of 
snow. Especially is this the case in driving along the post-road 
at the head of Port Mouton Harbor, whence, though at a 
distance of a mile or more, such drifts, in reality of blown sand, 
are readily seen, forming indeed a conspicuous feature of the 
landscape. They here occur upon the west side of the indenta- 
tion named, stretching along the latter, though somewhat 
jnterruptedly, for nearly a mile, and attaining in places a height 
of thirty or forty feet. They conceal for the most part from 
view the underlying rocks, but these, as seen in severai islands 
near by, are undoubtedly granitic, and such as, by their decom- 
position, might readily afford the pure white siliceous sand of 
which the dunes consist. This sand is almost wholly incoherent, 
and readily blown to and fro by the winds, while, near the 
water’s edge, quicksands occasionally become a source of danger 
to the incautious traveller; but why so great an accumulation of 
such material should take place at this particular spot is not 
directly obvious.
