They have been used to some extent by Course 14 in which 
laboratory work has been introduced as part of the instruction 
this year. Some material has been purchased from Ward’s 
Natural Science Establishment, and a considerable number of 
photographic diagrams have been added. Photographic diagrams 
are extremely desirable for class work, as they are faithful repro 
ductions of original published figures and at the same time are 
very moderate in cost. 
Professor Ward reports that, in accordance with the recommen- 
dation of the Committee on Improving Methods of Instruction, 
the hour of the course in Elementary Meteorology (Geology B) 
was changed from 11 a.m. to 3.30 p.M., the result being a reduc- 
tion of more than one-half in the number of students. The 
advantages of the afternoon hour are so great, however, that the 
lectures will be given at the same time during the year 1905-06. 
In Geology 2 (Climatology of the United States), many new 
laboratory exercises were given, in order that the time spent by the 
students might be more nearly that which the Committee on 
Instruction desires to have required in all courses. The result of 
these changes was a distinct gain in the understanding of the 
subject-matter of the course. Two theses in Geology 19 (General 
Climatology) have been accepted for publication. 
A most important step towards the improvement of the instruc- 
tion in Meteorology and Climatology has been taken in providing 
a proper place for a meteorological observatory. The anonymous 
gift of $200.00 has made it possible to erect on the roof of the Geo- 
logical Section of the University Museum a substantial platform, 
where all needed instruments may be set up, and instruction in 
practical instrumental work given. This platform was built in 
June, 1905, with the permission of Mr. Alexander Agassiz, Direc- 
tor of the University Museum. Some changes have been made in 
the stairway and in the door leading to the roof in order that 
access may be safe and easy. A portion of the attic directly 
beneath the platform will later be adapted as an instrumental 
work room. Several instruments will be in working order in 
January, 1906. As opportunity offers additional instruments will 
be purchased. The advantages of having this small working 
meteorological observatory for the use of students in Meteorology 
and Climatology will be very great, and the instruction in these 
subjects will be materially strengthened.
