In reasoning, however, on this subject as regards Nova Scotia, I have the advantage of appealing to causes now in operation within the country, and which are at present admitted by the greater number of modern geological authorities to aflford the best explanation of the phenomena. In the first place, it may at once be admitted that no such operations as those which formed the drift are now in progress on the surface of the land, so that the drift is a relic of a past state of things, in so far at least as regards t>ie localities in which it now rests. In the next place, we find, on examining the drift, that it strongly re- sembles, though on a greater scale, the effects now produced by frost and floating ice. Frost breaks up the surface of the most solid rocks, and throws down cliffs and precipices. Floating ice annually takes up and removes immense quantities of loose stones from the shores, and deposits them in the bottom of the sea or on distant parts of the coasts. Very heavy masses are removed in this way. I have seen in the Strait of Canseau large stones, ten feet in diameter, that had been taken from below low-water mark and pushed up upon the beach. Stones so large that they had to be removed by blasting, have been taken from the base of the cliffs at the Joggins and deposited off the coal-loading pier, and I iiave seen resting ou the mud-flats at the mouth of the Petitcodiac River a boulder at least eight feet in length, that had been floated by the ice down the river (Fig. 11). Another Fig. 11.â Travelled Slone, retitcodiac River. '. testimony to the same fact is furnished by the rapidity with which huge piles of fallen rock are removed by the floating ice
