At last they let him go, he whose barrow was full accompanying him to the end of the passageway, and speeding him on his way with this comfortable remark: "If you was to dive deep and feel around, you might find those as is leaded to the bottom." It took every ounce of nerve that Bubbles had at command to let his legs and body slip down into the cold and tragic current. It seemed certain that dead hands were reaching for him. But he screwed his courage up to the sticking point, and called to his acquaintance in the passage-mouth a whispered but nonchalant, "S'long!" XXX When Bubbles entered Blicker's drug-store, the city clocks were striking a quarter to twelve, but the place was still brightly lighted, and at the soda-counter a young man was treating his flame to a glass of chocolate vanilla ice-cream. Bubbles marched to the prescription counter, and began to unwrap a bloody handkerchief from his left hand. Then he began to clear his throat. This brought Mr. Blicker from a region of mortar pestles, empty pill-boxes, and glass retorts. "What you want?" he asked aggressively. "I want me thumb bandaged." "You cut him--eh?" Bubbles lowered his voice. "On a barnacle." "Come in back here," said Mr. Blicker roughly. "I fix him." But once out of sight in the depths of the store, his manner changed, and he patted Bubbles enthusiastically on the back. "You have found out some things?" "Sure--lots." The chemist, without commenting, began to treat the cut thumb, washing, disinfecting, and bandaging. Then, very loud, for the benefit perhaps of the lovers at the soda-counter, "So," he said, "I let you out the back door." And he actually opened a door, slammed it shut, and turned a key in the lock. But it was a closet door. Then with a finger on his lips he pointed to a narrow staircase and, his own feet making a great tramping, led the way up it. Upon the top steps they found Mr. Lichtenstein, nervously puffing clouds of tobacco smoke, "'Bout given you up," he said. "Good boy!" "Better talk by the parlor," said Blicker; "here is too exposed." When the door of the stuffy little parlor had closed behind them, the proprietor began to smile and beam. But Mr. Lichtenstein looked grave and troubled. It was not for pleasure that he sometimes found occasion to put dangerous work in the hands of children. "Hurt your thumb bad?" he asked. Bubbles shook his head and plunged into his story. Now and then the German laughed, but the red-haired, pug-nosed Jew appeared to sink deeper and deeper into his own thoughts, only showing by an occasional question that he was following the boy's narrative. Bubbles wished to dwell at length and with comment upon the use of the passage for disposing of dead bodies, but to Mr. Lichtenstein this appeared to be merely a natural by-product of its construction. "It wasn't dug for that," he said. "How big is the main excavation?" [Illustration: "I want me thumb bandaged"]
