21, as Assistant in Course 5 during the last two weeks of the 

 second half-year. The admission examinations in Physiography 

 were in charge of Mr. Smith, who reports a marked increase in the 

 number of candidates. Mr. Smith spent much time in the prepa- 

 ration of a thesis on the " Copper Sulphide Deposits of Orange 

 County, Vermont," which was accepted for the degree of Ph.D. 

 The degree was conferred in June, 1904. A summary of this 

 thesis, prepared with the collaboration of Professor H. L. Smyth, 

 was published in the " Engineering and Mining Journal," April, 

 1904. During six weeks of the summer of 1903, Mr. Smith con- 

 ducted a summer course in the study of mining operations (Mining 

 12), and visited most of the important gold and silver mines of 

 Colorado, as well as coal and copper properties, smelters, and 

 concentrating plants. In February, 1904, he made a week's trip 

 to Cape Cod, in order to study shore phenomena after a heavy 

 storm. During the summer of 1904 Mr. Smith was engaged in a 

 study of the surface features of the southeastern portion of Cape 

 Cod, in connection with an investigation regarding the retreat of 

 the ice sheet and the development of the present day topography.

 including views taken by Messrs. Gilbert, Walcott, Keith, Dale,
