RECENT PROGRESS IN DEPARTMENT OF GEOLOGY 



In spite of failing eyesight Dr. D. S. Martin has accomplished 

 much valuable work during the past three months. The Pied- 

 mont collection of minerals, which has been described in the 

 Bulletin*, has been systematically arranged and completely 

 cataloged. In an informal report to the director Dr. Martin 

 defines the purposes of this collection as three-fold: (1) To illus- 

 trate the mineralogy of the southern crystalline belt of rocks. 

 (2) To illustrate the resemblances and differences in the mode 

 of occurrence of these rocks throughout the region. (3) To trace 

 the connection or relation mineralogically and geologically of 

 this region as a whole with what appears to be its northern ex- 

 tention in Pemisylvania, New York, and New England. Al- 

 though far from complete the Piedmont collection already com- 

 prises over five hundred entries and illustrates most of the prin- 

 cipal points of interest. The general discussion of the mineral- 

 ogical relations of this region is a much larger task and one which 

 may not be completed for some time. 



Dr. Martin has co-operated with Miss Bragg in the preparation 

 of labels to be used in extending the installation of the general 

 collection of minerals. The style of labeling adopted in the sec- 

 tion already installed is intended to give to the average visitor 

 the information most likely to be of interest and value to him re- 

 garding the minerals displayed. Several very gratifying expres- 

 sions of approval of this plan of labeling have been received from 

 visiting scientists. 



Mr. Earle Sloan, recently state geologist of South Carolina, has 

 been engaged in the arrangement of the extensive collection of 

 fossils and minerals which he deposited in the Museum last year. 

 Cases have now been prepared in the main hall for the installa- 

 tion of a part of this collection.
