Sam Folwell stood where two great, rectangular arteries of the city cross. He looked four ways, and saw the world hurled from its orbit and reduced by spirit level and tape to an edged and cornered plane. All life moved on tracks, in grooves, according to system, within boundaries, by rote. The root of life was the cube root; the measure of existence was square measure. People streamed by in straight rows; the horrible din and crash stupefied him. Sam leaned against the sharp corner of a stone building. Those faces passed him by thousands, and none of them were turned toward him. A sudden foolish fear that he had died and was a spirit, and that they could not see him, seized him. And then the city smote him with loneliness. A fat man dropped out of the stream and stood a few feet distant, waiting for his car. Sam crept to his side and shouted above the tumult into his ear: "The Rankinses' hogs weighed more'n ourn a whole passel, but the mast in thar neighborhood was a fine chance better than what it was down--" The fat man moved away unostentatiously, and bought roasted chestnuts to cover his alarm. Sam felt the need of a drop of mountain dew. Across the street men passed in and out through swinging doors. Brief glimpses could be had of a glistening bar and its bedeckings. The feudist crossed and essayed to enter. Again had Art eliminated the familiar circle. Sam's hand found no door-knob--it slid, in vain, over a rectangular brass plate and polished oak with nothing even so large as a pin's head upon which his fingers might close. Abashed, reddened, heartbroken, he walked away from the bootless door and sat upon a step. A locust club tickled him in the ribs. "Take a walk for yourself," said the policeman. "You've been loafing around here long enough." At the next corner a shrill whistle sounded in Sam's ear. He wheeled around and saw a black-browed villain scowling at him over peanuts heaped on a steaming machine. He started across the street. An immense engine, running without mules, with the voice of a bull and the smell of a smoky lamp, whizzed past, grazing his knee. A cab-driver bumped him with a hub and explained to him that kind words were invented to be used on other occasions. A motorman clanged his bell wildly and, for once in his life, corroborated a cab-driver. A large lady in a changeable silk waist dug an elbow into his back, and a newsy pensively pelted him with banana rinds, murmuring, "I hates to do it--but if anybody seen me let it pass!" Cal Harkness, his day's work over and his express wagon stabled, turned the sharp edge of the building that, by the cheek of architects, is modelled upon a safety razor. Out of the mass of hurrying people his eye picked up, three yards away, the surviving bloody and implacable foe of his kith and kin. He stopped short and wavered for a moment, being unarmed and sharply surprised. But the keen mountaineer's eye of Sam Folwell had picked him out.
