Mr. H.M. McCully Carnegie Institute of Technology Schenley Park, Pittsburgh, Pa. Dear Mr. McCully: Mr. Earl Douglass has enclosed to me your letter regarding the trees on his property over which there ahs been some controversy. He has written me, however, asking me to have the two trees removed, and, as I do not know anything of the workmen in that vicinity, could you possibly give me the address of some one who could do this work.
