The authorities of the institute are not looking forward to 
» policy of expansion. It is not expected that the enrollment 
will be permitted to grow much beyond the present number 
except in the evening classes, in which the students will be 
accepted up to the capacity of the shops, laboratories, and 
class-rooms. This number has already been reached in many 
departments. 
In the field of research, the Carnegie Institute of Tech- 
nology is devoting itself especially to metallurgy and coal. 
It is in these branches that it feels it can do most for the Pitts- 
burgh district. At present it is approaching the study of 
these subjects partly from a theoretical point of view, but 
what is an abstraction today may be of great importance in a 
oractical sense tomorrow. 
The Institute of Technology enjoys noteworthy advan- 
tages through having as a background the city and district of 
Pittsburgh, the industrial production of which annually 
exceeds in its tonnage that of any other city in the world. 
The diversity and perfection of technological practice in- 
volved in this production and at the range of industries con- 
iributing to it are distinctive assets. 
The City of Pittsburgh has reached its great importance 
as an industrial center largely through the application of 
scientific principles. It is, therefore, essential that its educa- 
tional institution do all that is possible to advance the cause 
of science. The advantages that come to an industrial com- 
munity through the presence of a great school of engineering 
are obvious. The necessity of encouraging work in the field 
»f abstract research may not be so clear, but progress in 
technology in the long run can be achieved only through ad- 
vancement in the fundamental sciences. 
ARNOLD SCHOOL 
Arnold School, a college preparatory school for boys, 
because of its beautiful location on a seven acre site within 
the city limits, justly may be termed “A Country Day 
School in the City”. 
The school had its inception in the old George H. Thurs- 
ton School which was founded in 1908, which was situated on
