A few years ago Professor McAdie was able to show that a marked 
and peculiar disturbance recorded on the mareograph (self-re- 
cording tide gage) of the U. S. Coast Survey in San Francisco Bay, 
and thought to be due to a submarine earthquake, was in fact due 
to atmospheric causes. With a good mareograph in Boston harbor 
(and assistance of the Coast Survey could be depended upon) 
and a seismograph at Blue Hill in addition to the existing equip- 
ment, it would be possible to follow closely and correlate the larger 
vibrations which are transmitted through earth, water, and air 
at certain times, due to volcanic or tectonic disturbances. 
Prof. H. L. Smyth gave his new, advanced course on the geology 
of iron ores to six students. 
Professor Ward reports:— The courses’ in Meteorology and Cli- 
matology, hitherto designated Geology 1, 2, etc., have been given 
the designation of Meteorology 1, 2, ete. This change was de- 
sirable in view of the increase in the number of these courses, and 
because of the confusion which has frequently arisen on account 
of the use of the term Geology in connection with courses in 
Meteorology and Climatology. A new half-course on the Clima- 
tology of South America, given for the first time in 1913-1914, was 
elected by 9 students. ‘This course replaces that on the Geography 
of South America, which has been withdrawn. The most impor- 
tant addition to the laboratory equipment was an Assmann Aspira- 
tion Psychrometer, purchased during the year. The large model 
of the United States showing mean annual isotherms and isohyetal 
lines was removed from the Geological Museum Exhibition Rooms 
and placed on the wall of Professor Ward’s small lecture room, 
where it is more accessible to students of Climatology. Mr. 
Charles F. Brooks, Assistant in Meteorology, completed a thesis 
on the Snowfall of the Eastern United States, as a part of the work 
for his Ph.D. degree. Owing to the completion of the new ex- 
tension of the Peabody Museum, it was desirable to move the win- 
dow shelter in Room 43 from the east to a south window. During 
the winter, Professor Ward devoted much time to the preparation 
of a discussion of the weather element in American climates. 
This paper will shortly be published. In the summer of 1914, he 
prepared a series of lectures on the Climatology of the: Eastern 
_ Hemisphere, for a new half-course in that subject. 
_ Geology 8 was conducted by Professor A. C. Lane and Geology 
12 by Mr. Haynes until about Dec. 1, when Professor Woodworth 
resumed his duties. Courses 4, 5, 8, and 16 were also given to 
_ students in Radcliffe College. In July-August, 1914, Professor
