Sir Charles Cotton's achievement might well be left to speak for itself, as may be confirmed from the Bibliography that follows this section. Yet it may not be thought out of place to record here some previously unpublished comments and some perhaps little known facts concerning his career that may indicate something of Cotton's place in earth science in New Zealand and in geomorphology in particular. In addition, there are reproduced a few typical extracts from reviews of his works by well known overseas geologists and geomorphologists; some tributes from his colleagues and admirers in Belgium, France, Russia, and Japan; and some examples of his widely praised landscape sketches and block diagrams.
