GEOLOGY AND SCENERY OF NORTHEAST COAST 129 
directness and with lavish proofs this ground principle of 
geology is illustrated on the Labrador. 
The memorials of post-Glacial uplift are as diverse as 
the kinds of shore-line form which the waves of to-day are 
impressing on the hard rocks of the coast. Boulder beaches, 
gravel beaches and terraces, plains and pointed spits of wave- 
laid sand, sea-cliffs, splendid sea-caves and long chasms, 
even the dunes of sand blown up on these prehistoric shores, 
remain to tell us of just such activities as wind and wave dis- 
play on the present shore, the lowest of all those which the 
Atlantic has stormed and battered since the Glacial Period. 
Ocean waves are like rivers and glaciers in their ways of 
working. They destroy or erode bed-rock; they transport 
the eroded débris; they deposit their freight of rubbish 
where the force of wave- and wind-driven current is lowered. 
Thus, in a sense, the gnawed and riven sea-cliffs correspond 
to the scoured glacier-bed or washed, abraded floor of the 
river-canyon; the beaches and spits, the bedded sand and 
mud of the sea-bottom correspond to moraines and to the 
deltas and alluvial plains of rivers. As the outer coastal 
belt of the Labrador slowly, with the deliberation of mil- 
lenniums, and urged by the mysterious, colossal, internal 
energy of a planet, rose out of the sea, the ocean-billows 
rolled in upon the changing shores, destroying where they 
could, constructing where they must. The visible signs of 
the submergence belong, therefore, to two classes of land- 
scape forms which give a real fascination to this most recent 
geology on the coast. 
The most widespread evidence of the destruction wrought 
by the waves on the old shore-lines can be found at almost 
any landing-place between St. John’s and Cape Chidley.
