In view of the immense mineral resources of our country, provision should also be made for the employment of a competent mineralogist and chemist, who should be required, under the direction of the head of the bureau, to collect specimens of the various minerals of our country and to ascertain by careful analysis their respective elements and properties and their adaptation to useful purposes.

An eminent mineralogist assures me that he is able to imagine simultaneously all the sides of a crystal with which he is familiar.
