has been drifted from the shore by high winds, has formed hills or 
dunes of white sand that extend a considerable distance from the 
shore, at Tucker’s Town, burying the once fertile soil. This has been 
going on here for about a hundred and twenty-five years. The loose 
sand of the dunes has not yet been stayed in its destructive progress 
by the binding roots of various shrubs and grasses that will grow in 
such soil, though the area of loose sand has already been much 
diminished by them. (Plates Ixxv, Ixxvi, and see Physiography, 
ch. 10.) | 
_ These are now the only important active, or moving, sand-dunes 
on the islands, though there were other even more extensive ones a 
few years ago, especially near Elbow Bay, all of which have now 
been stayed by the vegetation. At the latter place they formerly 
buried, in their irresistible progress, a dwelling, all except the chim- 
ney, and also groves of cedars. 
Figure 14.—Lion Rock and Harrington Sound. 
At arocky promontory, interrupting the beach, there is a very 
interesting rock-sculpture, consisting of two large, well formed 
arches, side by side, and separated by a massive central pillar of 
limestone. (Plate lxxxvii.) 
The south road also passes close by “Lion Rock,” a curious rock- 
sculpture, carved by the waves, and so named from its form.
