In Schenley Park is the Carnegie Institute, with its new main building, dedicated in April (11, 12, and 13), 1907, with imposing ceremonies which were attended by several hundred prominent men from America and Europe. This building, which is about six hundred feet long and four hundred feet wide, contains a library, an art gallery, halls of architecture and sculpture, a museum, and a hall of music; while the Carnegie Technical Schools are operated in separate buildings near by. It is built in the later Renaissance style, being very simple and yet beautiful. Its exterior is of Ohio sandstone, while its interior finish is largely in marble, of which there are sixty-five varieties, brought from every famous quarry in the world. In its great entrance hall is a series of mural decorations by John W. Alexander, a distinguished son of Pittsburgh. The library, in which the institution had its beginning in 1895, contains about 300,000 volumes, has seven important branches, and one hundred and seventy-seven stations for the distribution of books. Mr. Edwin H. Anderson inaugurated the library at the time of its creation, and, after several years of successful service, was followed by Mr. Anderson H. Hopkins, and he by Mr. Harrison W. Craver, who is now the efficient librarian. The Fine Arts department contains many casts of notable works of architecture and sculpture, sufficient to carry the visitor in fancy through an almost unbroken development from the earliest times in which man began to produce beautiful structures to the present day. It is now the aim of this department to develop its galleries on three lines: first, to gather early American paintings from the very beginning of art in this country; second, to acquire such portraits of eminent men as will, in the passage of years, make these halls to some extent a national portrait gallery; and, third, to obtain such pieces of contemporary art as will lead to the formation of a thoroughly representative collection of modern painting. The Art Gallery is already rich in this latter purpose, and is renowned for its annual competitive exhibits which are open to the artists of all countries for prizes offered by the Carnegie Institute. Mr. John W. Beatty, Director of Fine Arts, has made the building up of this department his ripest and best work. The Museum embraces sections of paleontology, mineralogy, vertebrate and invertebrate zooelogy, entomology, botany, comparative anatomy, archaeology, numismatics, ceramics, textiles, transportation, carvings in wood and ivory, historical collections, the useful arts, and biological sciences. Its work in the department of paleontology is particularly noteworthy as it has extended the boundaries of knowledge through its many explorations in the western fossil fields. The success of the Museum is largely due to the energy and erudition of Dr. W. J. Holland, its amiable director. In the music-hall, a symphony
