First Visit To Middle Waipara—1866.

Before starting again for a longer journey into the Southern Alps, I wished to examine the interesting region of the Middle Waipara where, for some years past, Saurian bones and skeletons had been page 123found, as I was not only anxious to make a collection of these interesting fossils, but I hoped also to be able to fix the horizon in which they were embedded. On January 23rd (1866) I started for this region, where I remained for several days occupied in making a geological investigation of this highly important zone, although the weather remained unsettled, and we had some trouble with the rivers, which continued [unclear: to] be high and scarcely fordable. In the geological portion of this Report some details will be found on this district, of which it can truly be said that it offers us the key to unravel the relations in which our young secondary and old tertiary beds stand to each other.
