Mr. Rockefeller's third gift was made in February, 1892, "one thousand five per cent bonds of the par value of one million dollars," for the further endowment of instruction. In December of the same year he gave an equal amount for endowment, "one thousand thousand-dollar five per cent bonds." In June, 1893 he gave $150,000; the next year, December, 1894, in cash, $675,000. On Jan. 1, 1896, another million, promising two millions more on condition that the University should also raise two millions. Half of this sum was obtained at once through the gift of Miss Helen Culver. In her letter to the trustees of the University, she says, "The whole gift shall be devoted to the increase and spread of knowledge within the field of biological science.... Among the motives prompting this gift is the desire to carry out the ideas, and to honor the memory, of Mr. Charles J. Hull, who was for a considerable time a member of the Board of Trustees of the old University of Chicago." Miss Culver is a cousin of the late Mr. Hull, who left her his millions for philanthropic purposes. Their home for many years was the mansion since known as Hull House. The University of Chicago has been fortunate in other gifts. Mr. S. A. Kent of Chicago gave the Kent Chemical Laboratory, costing $235,000, opened Jan. 1, 1894. The Ryerson Physical Laboratory, costing $225,000, opened July 2, 1894, was the gift of Mr. Martin A. Ryerson, as a memorial to his father. Mrs. Caroline Haskell gave $100,000 for the Haskell Oriental Museum, as a memorial of her husband, Mr. Frederick Haskell. There will be rooms for Egyptian, Babylonian, Greek, Hebrew, and other collections. Mr. George C. Walker, $130,000 for the Walker Museum for geological and anthropological specimens; Mr. Charles T. Yerkes, nearly a half million for the Yerkes Observatory and forty-inch telescope; Mrs. N. S. Foster, Mrs. Henrietta Snell, Mrs. Mary Beecher, and Mrs. Elizabeth G. Kelley have each given $50,000, or more, for dormitories. It is expected that half a million will be realized from the estate of William B. Ogden for "The Ogden (graduate) School of Science." The first payment has amounted to half that sum. Considerably over $10,000,000 have been given to the University. The total endowment is over $6,000,000.
