ABSTRACT OF REPORT ON TEACHERS’ SCHOOL OF SCIENCE, 
BY PROF. G. H. BARTON, CURATOR OF THE SCHOOL. 
During the year the usual field and laboratory courses have been 
given. 
The field courses in botany, under the charge of Mr. Hollis Webster, 
were mainly devoted to a study of the relationships of the flowering 
plants. The average attendance w T as 21 in the spring and 12 in the 
autumn. 
The field work in zoology, under the charge of Mr. A. P. Morse, 
was devoted to the study of insects in the spring, and in the autumn, 
to the study of the native mammals. The average attendance during 
the spring was 9, and in the autumn, 15. 
The course in field geology, supported by a friend of the School, is 
under the charge of the Curator of the School. The spring work was 
devoted mainly to a study of structural geology, and the autumn 
lessons consisted of a definite course of instruction in erosion of the 
earth’s surface. The average attendance for the spring was 34, and 
for the autumn 53. 
The laboratory courses in botany and zoology, which finished their 
four years with the winter of 1904—05, were each extended over a fifth 
year so that new classes for a four years’ course could be formed. 
This additional year gave an opportunity in botany to try the experi¬ 
ment of a course in plant physiology. The average attendance for the 
term was 23. 
The laboratory work in zoology was devoted to the study of verte¬ 
brate anatomy, with an average attendance of 21 for the seventeen 
lessons. 
Two classes are now conducted in laboratory geology. The one is 
two years in advance of the other in its work, and this year took up the 
subject of historical geology. The average attendance for this course 
was 62. The other class, now in its second year, took up the subject 
of lithology, with an average weekly attendance of 38. 
In addition to the regular work of the School, a course of eight 
lectures on the topographic features of the United States was given by 
Dr. D. W. Johnson of the Massachusetts institute of technology, with 
an average attendance of 98. The expense of this extra course was
