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
