In addition to the running advertisement of the state of affairs carried to him by his senses, he had a subtler perception, a FEEL, of the atmosphere around him. He knew that the house in front of which he paused for a moment, contained children. Yet by no willed effort of perception did he have this knowledge. For that matter, he was not even aware that he knew, so occult was the impression. Yet, did a moment arise in which action, in relation to that house, were imperative, he would have acted on the assumption that it contained children. He was not aware of all that he knew about the neighbourhood. In the same way, he knew not how, he knew that no danger threatened in the footfalls that came up the cross street. Before he saw the walker, he knew him for a belated pedestrian hurrying home. The walker came into view at the crossing and disappeared on up the street. The man that watched, noted a light that flared up in the window of a house on the corner, and as it died down he knew it for an expiring match. This was conscious identification of familiar phenomena, and through his mind flitted the thought, “Wanted to know what time.” In another house one room was lighted. The light burned dimly and steadily, and he had the feel that it was a sick-room. He was especially interested in a house across the street in the middle of the block. To this house he paid most attention. No matter what way he looked, nor what way he walked, his looks and his steps always returned to it. Except for an open window above the porch, there was nothing unusual about the house. Nothing came in nor out. Nothing happened. There were no lighted windows, nor had lights appeared and disappeared in any of the windows. Yet it was the central point of his consideration. He rallied to it each time after a divination of the state of the neighbourhood. Despite his feel of things, he was not confident. He was supremely conscious of the precariousness of his situation. Though unperturbed by the footfalls of the chance pedestrian, he was as keyed up and sensitive and ready to be startled as any timorous deer. He was aware of the possibility of other intelligences prowling about in the darkness--intelligences similar to his own in movement, perception, and divination. Far down the street he caught a glimpse of something that moved. And he knew it was no late home-goer, but menace and danger. He whistled twice to the house across the street, then faded away shadow-like to the corner and around the corner. Here he paused and looked about him carefully. Reassured, he peered back around the corner and studied the object that moved and that was coming nearer. He had divined aright. It was a policeman.
