Transcriber’s Note:

A complex full-page chart, ‘TABULAR GEOLOGICAL PROFILE’, appeared as p. 3, in mid-paragraph, and has been moved slightly forward. It is presented here as a single image. The link provided below the chart will direct the reader to a text rendition, found at the end of the text.

There are also a number of large maps. Each one is represented in the text by reduced size version, with a [Larger view] link associated with it. This can be used to access a larger, more useful image.

In general, the position of illustrations have been adjusted slightly, where necessary, to avoid falling in mid-paragraph.

Minor errors in punctuation and formatting have been silently corrected. Please see the transcriber’s note at the end of this text for details regarding the handling of any textual issues encountered during its preparation.
