Geology of the Provinces of Canterbury and Westland, New Zealand : a report comprising the results of official explorations
Several important questions regarding the Canterbury plains having been raised, as to the flow of the River Waimakariri and other points having reference to engineering works, the Secretary for Public Works instructed me to report on the formation of those plains. During the winter months I visited several localities not previously examined, so that I became acquainted with all the rivers from the Ashley north to the Rangitata south, having followed their course from the sea to the point where they enter from the mountains on the plains. This report was furnished to the Secretary for Public Works on September 2nd, 1864, and printed by order of the Provincial Council. † As the principal portion of that report will be incorporated in the geological portion of this publication, I need not allude any further to its contents.
