The principal buildings entirely of Canetd pee in Dansain are :—The 
University, First Church and Manse, Union and New South Wales Banks, 
Fernhill, and the Pier Hotel. In Oamaru, nine-tenths of the buildings are 
of this material, and several of them, such as the National Bank and the 
Star and Garter Hotel, are worthy of a place with the architecture of the 
old world. The private residences in that district can also be classed along 
with the country houses of England, notably Windsor Park, Elderslie, 
Moa, and Totara. The stone has also been used in numerous road naa 
railway bridges, many of them of considerable span. 
The granular limestone found in Southland resembles closely the Oamaru 
variety in composition and colour; it is, however, a little coarser in the 
grain, and, if anything, harder and more compact. Large deposits are 
known to exist at Aparima Castle Rock, and several adjacent points, but 
hitherto it has been little utilized. 
Sandstones.—The sandstones of Otago are as varied in consistency and 
more numerous than the limestones, but excel them in diversity of colour. 
The extremes in the latter are generally connected by gradations of blue 
and gray ; but sandstones merge into all conceivable shades and hues. 
As already stated, the Craigleith sandstone, the analysis of which has 
been given, is the best in Great Britain. It is, however, too hard for many 
purposes, so the Midland and Scotch stones, that have five or ten per cent. 
less silica, may be taken as the type of a good and useful building material. 
A corresponding type, in the colonial product, is found in the Tasmanian 
freestone, of which the High School, Custom House, and Cargill monu- 
ment are built; it contains 86 per cent. of silica. Any Otago sandstone 
that has so much of this base, and has a hard compact texture, may be con- 
sidered strong, durable, and dry. 
The highest class of sandstones, as regards their relation with the hard 
stones, are grits. These abound throughout the Province, chiefly in the
