Excerpt: 'When the light of morning touches the buildings and pavements of a city, it always seems to borrow their hardness and to lose in some degree its quality of flowing detachment. The Sunday morning that fell upon Ninth Avenue, New York City, gave you a sense of invisible stiffness in its very air. The buildings, with their smudged, flat fronts and tops, presented the impression of huge warehouses stretching down both sides of the street-the appearance of holding commodities rather than human beings. Most of them were five or six stories in height, and their curtained, oblong windows and the bright, tawdry shops at their base had an oddly lifeless aspect, in spite of the sounds and animations which occurred within and around them. The iron elevated-railroad structure that extended down the street, with all of its roar and rush of trains, could not destroy the spirit of silent inertia that lurked within the scene.'
