22 ANNUAL REPORT OF THE 



maining three weeks longer in the field. Having gained some 

 skill in field methods, the student remaining the three additional 

 weeks under instruction would profit perhaps more than by the 

 first five weeks in the field. 



Under the auspices of the U. S. Geological Survey, Professor 

 Atwood has continued his studies of the physiography of the San 

 Juan region. In association with students he has taken up the 

 systematic study of the glacial deposits in and around Boston. 

 During this work one of the students has discovered in Boston a 

 pre- Wisconsin drift sheet. 



Before the close of the year, Professor Atwood's Shaler Memorial 

 study of the physiography of certain mining regions in relation 

 to the secondary enrichment of ores was prepared for publication. 

 An account of Eocene glacial deposits in southwestern Colorado 

 was published by the U. S. Geological Survey as Professional Paper 

 95-B. 



Mr. Clifford Swan of the class of 1908 presented a number of 

 government reports for use in the geographical laboratory. 



Professor Ward reports an increase in the number of students 

 in the elementary course, Meteorology I, from 18 to 54. A new 

 half course on the Climatology of the Eastern Hemisphere (Meteor- 

 ology 5) was given for the first time. The establishment of this 

 course satisfactorily rounds out the instruction which the Depart- 

 ment is able to offer in Meteorology and Climatology. The 

 climatological courses now cover all parts of the world. An ideal 

 which has been before the Department for a quarter of a century 

 has therefore been attained. The laboratory equipment has been 

 increased by the purchase of the Oxford wall maps not previously 

 in the collection, and of photographic enlargements of a consider- 

 able number of generalized type weather maps of the United States, 

 selected and prepared by Professor Ward. Most of the bound 

 volumes of meteorological journals which have for some years 

 been deposited in the Climatological Laboratory, were transferred 

 to the Harvard University Library, where they are more easily 

 accessible to a larger number of persons. The laboratory work 

 in elementary Meteorology would be greatly improved and stimu- 

 lated if the ordinary instruments (thermometers, rain-gauge, etc.) 

 could be exposed outdoors, under standard conditions, in some 

 convenient location on the grounds close to the Geological 

 Museum. 



During the winter Professor Ward gave two public lectures on 

 the Weather factor in the great war; one in the series on the
