Late in April, just before the aeon-shadowed Walpurgis time, Blake made his first trip into the unknown. Plodding through the endless downtown streets and the bleak, decayed squares beyond, he came finally upon the ascending avenue of century-worn steps, sagging Doric porches, and blear-paned cupolas which he felt must lead up to the long-known, unreachable world beyond the mists. There were dingy blue-and-white street signs which meant nothing to him, and presently he noted the strange, dark faces of the drifting crowds, and the foreign signs over curious shops in brown, decade-weathered buildings. Nowhere could he find any of the objects he had seen from afar; so that once more he half fancied that the Federal Hill of that distant view was a dream-world never to be trod by living human feet.
