One hot summer evening I was asked to dine at the University Club, and this drawing is the result. I had no idea that I would get anything but—as one always does in Philadelphia—a good dinner. I have forgotten the good dinner and the doubtless good talk, but I shall never forget the towering buildings, in the coming night, grouped round the low houses, and the dark hole from which the steel skeleton was emerging, soon to become higher and mightier than the grim masses amid which it was growing. So I came back the next day and drew it.
