AND MINERALS, OF NEW ZEALAND. 79 
every friend to civilization, and to the welfare 
of man. 
Of minerals, little, as yet, is known. Opportu- 
nities have not yet been afforded for much mine- 
ralogical or geological research. It is supposed, 
however, that the hills contain iron-stone in 
abundance : and whinstone is very plentiful on 
the banks of many of the rivers, which affords 
an admirable and never-failing supply of mate- 
rials for rough, unpolished buildings. We have 
also found quarries of granite, specimens of 
quartz, carbonate of lime, fine marble, sulphuret 
of iron, &c. &c.
