distribution of blacksand on the raised beaches of the west coast of the 
South Island, suggest the uplift in New Zealand took place in a manner 
similar to that of South America. 
If the elevation of the land is fairly uniform, though interrupted by 
riods of rest or slight depression, there will be places, on a coast so 
diversified as that of New Zealand, where the emerging wave-formed shelf 
will be (1) prograded, (2) unaltered, (3) partially destroyed, and (4) wholly 
destroyed. In the first case the surface of the coastal terrace will be fairly 
discharge by another outlet may alter locally the distribution of the coastal 
drift. Hence, though the whole coast may have been uniformly subjected 
to a series of oscillations, the full bistory of the oscillations may not 
decipherable in any one area, and different chapters of the history must 
be read in different districts. 
EVIDENCE OF ELEVATION, 
The evidences of elevation will first be considered, and, in order that the 
facts may be conveniently presented, the coast óf each Island is divided
