Dr. Wyman had found an eager companion in his studies and excursions, during several years preceding his death, in Frederick W. Putnam, who was almost the only man in the neighborhood of Boston having either interest or capability (not to speak of opportunity) for such pursuits. A Salem lad, he was one of that group of students whom the elder Agassiz gathered round him when he began teaching at Harvard,--a group comprising Alpheus Hyatt, A. E. Verrill, J. A. Allen, Edward S. Morse, N. S. Shaler, A. S. Packard, Jr., and others now of worldwide reputation. Putnam was an all-round zoologist, but his specialty was fishes. Accident, nearly thirty years ago, turned his attention to the shell-heaps and the primitive implements of his home-neighborhood. The only man to whom he could go for guidance in studying these was Dr. Jeffries Wyman, at that time his instructor in comparative anatomy. Thus the two men were drawn more and more together, and when Wyman organized the new museum Putnam found much time for helping him, although at that time he was in charge of the Salem Museum, an editor of "The American Naturalist," a publisher, and the permanent secretary of the American Association for the Advancement of Science, a position which he still retains. It happened, consequently, that upon Dr. Wyman's decease Mr. Putnam was the only man suitable and available to become his successor, and he was quickly appointed to fill the vacancy. Sixty thousand dollars of the original fund had been set aside by Peabody as a building-fund, but he decreed that this sum should be allowed to grow until it amounted to at least a hundred thousand dollars. This limit was attained in ten years, and in 1876 a building was begun for the accommodation of the museum. The college gave the ground,--a lot on Divinity Avenue, nearly opposite the old Divinity School, and close to the great structure occupied by the Museum of Comparative Zoology. Surrounded by green lawns and avenues of old trees, it is the pleasantest spot in all that charming city. The building was completed and entered in 1878. It is of brick, four stories in height, thoroughly fire-proof, simple in design, and tasteful in ornamentation. The present structure is only a fifth of what the whole building is designed ultimately to be. Two rooms yet remain to be opened to the public, but their fitting will not long be delayed. Its spacious doors open on Divinity Avenue, and there let us enter and glance at its treasures. The entrance-hall is a square well in the centre of the building, accommodating the broad stairways and galleries, and affording room for many large objects, such as carved figures of stone and the models of the ruined houses and present pueblos of the village Indians of the Southwest. The walls are of finished brick.
