Excerpt from Summary Report of the Geological Survey Department: For the Year 1897 As explained in previous Summary Reports, the detailed examina tions of special districts and the elaboration of reports and maps upon these, as well as other investigations carried out along particular lines, often require several years for their satisfactory completion. It has now for some time been the practice to print and publish the results of such work in separate form whenever completed, thus rendering it at once available to the public, and subsequently to issue such reports of permanent value in a collected form as a volume, properly indexed, which is distributed to Parliament and to such public institutions, libraries and exchanges as are entitled to receive it.
