“ The enormous length attained in remote times by the New Zealand glaciers is evident on all hands at the lower parts of the valleys, the heads of which they now occupy; whilst the formation of nearly all the lakes in the South Island can be traced to the action of ice and the deposition of terminal moraines, prior to a period of retreat of the ice. ”

“ Volcanic action has long since ceased throughout the South Island; but there are many active volcanoes in the North, where a perfect wonderland of hot-springs, solfataras, and silica terraces exists.
As a whole, the country is heavily timbered—more thickly on the western parts, where the greater rainfall occurs. This is notably the case in the South Island, where the hot and moisture laden winds from tropical regions are deprived by the Alpine chain of their aqueous vapour. ”

“ The Southern Alps proper may be said to extend over a distance of about one hundred miles of the middle part of the South Island, the chain being situated closer to the western than the eastern ocean. The slopes on the western side are the more precipitous, and are clothed with heavy timber and intersected by innumerable mountain torrents, fed in most cases by glaciers, some of which descend to within 600 feet of sea-level. ”
