The old man could not at once get his voice: then he pumped out a scattering and hardly coherent salutation, and followed it with-- "Walk in, walk right in, Mr .-- er--" "Tracy--Howard Tracy." "Tracy--thanks--walk right in, you're expected." Tracy entered, considerably puzzled, and said: "Expected?
