Away over on the ragged eastern edge of the city it starts, out of a ferry-house or else upon the abrupt water-front with river waves slapping against the solid bulwark. Here are open, free sky, wide horizon, the smell of the water, or else of the neighboring gas-house, brisk breezes and sea-gulls flapping lazily. The street's progress begins between an open lot where rival gangs of East Side boys meet to fight, on one side, and, on the other, a great roomy lumber-yard, with a very small brick building for an office. A dingy saloon, of course, stands on the corner of the first so-called avenue. Away over here the avenues have letters instead of numbers for names. Across the way--and it is easily crossed, for on some of these remote thoroughfares the traffic is so scarce that occasional blades of grass come up between the cobble-stones--is a weather-boarded and weather-beaten old house of sad mien, whose curtainless gable windows stare and stare out toward the river, thinking of other days.... Some warehouses and a factory or two are usually along here, with buzz-saws snarling; then another lettered avenue or two and the first of the elevated railroads roars overhead. This is now several blocks nearer the splendor of Fifth Avenue, but the neighborhood does not look it, for here is the thick of the tenement district, with dingy fire-escapes above, and below in the street, bumping against everyone, thousands of city children, each of them with at least one lung. The traffic is more crowded now, the street darker, the air not so good. Above are numerous windows showing the subdivisions where many families live--very comfortably and happily in numerous cases; you could not induce them to move into the sunshine and open of the country. Here, on the ground floor of the flat, is a grocery with sickening fruit out in front; on one side of it a doctor's sign, on the other an undertaker's. The window shows a three-foot coffin lined with soiled white satin, much admired by the wise-eyed little girls. [Illustration: Up Beekman Street.
