In his will and in his instructions to the trustees of the university and the hospital, Hopkins requested that both institutions be built upon the vast grounds of his Baltimore estate, Clifton. When Gilman assumed the presidency, he decided that it would be best to use the university's endowment for recruiting faculty and students, deciding to, as it has been paraphrased, "build men, not buildings." In his will Hopkins stipulated that none of his endowment should be used for construction; only interest on the principal could be used for this purpose. Unfortunately, stocks in The Baltimore and Ohio Railroad, which would have generated most of the interest, became virtually worthless soon after Hopkins's death. The university's first home was thus in Downtown Baltimore delaying plans to site the university in Clifton.
