conducted in the region of Devils Lake, Wis- 

 consin, the area studied covering about 300 

 square miles. The party is to camp at the 

 north end of Devils Lake, near the center of 

 the area studied, and the field work continues 

 a month. After the field work a report is 

 made, after the general plan of the United 

 States Geological Survey. Another region for 

 field work in geology is to be Ste. Genevieve 

 County, Missouri, where are shown a large 

 number of geological phenomena in a small 

 area, as many as twenty distinct formations 

 being exposed. Collections of fossils from the 

 various formations will be made, which later 

 may be used as the basis for laboratory study 

 at the university. Another area designated for 

 geological study during the summer quarter is 

 that part of the Cascade Range between Mt. 

 Hood and the Columbia River, where may be 

 had first-hand acquaintance with valley gla- 

 ciers, a great volcanic cone, recent lava flows 

 and the records of at least six geological 

 epochs. This course is open only to men who 

 can " rough it," and the party -is to meet at 

 Portland, Oregon, on August 1, for a month's 

 work. A field course is also to be given in the 

 Lower St. Lawrence Valley, one of the most 

 interesting regions geographically in eastern 

 North America, where plain, highland and 

 maritime conditions are often found in close 

 proximity. Scenically also the region is fa- 

 mous, and Montreal, Quebec, French Canada 

 and the eastern provinces afford many oppor- 

 tunities to relate geography to history as well 

 as to present conditions. September will be 

 given to this course and only graduate students 

 can enter it.

DISCUSSION AND CORRESPONDENCE 



RESULTS OF A STUDY OF DOLOMITIZATION 



The writer believes that most dolomites were 

 formed in the sea. Facts favoring this view 

 are: (1) Dolomites and limestones are fre- 

 quently interstratified. (2) Dolomitization is 

 often related to original structures such as bed- 

 ding, worm borings, etc., but rarely to faults 

 and joints and other secondary structures. 

 (3) Both mineralogical and chemical studies of 

 limestones and dolomites show that limestones 

 free or nearly free from dolomite, and dolo- 

 mites nearly free from calcite are vastly more 

 common than beds composed of mixtures of 

 limestone and dolomite. If most dolomites 

 had resulted from the action of underground 

 waters, gradations between limestone and dolo- 

 mite ought to be common. (4) Calcite fossil 

 casts are often embedded in dolomite. Hollow 

 casts are frequently enclosed by perfect dolo-
