"I think you boys are about even now," said the Doctor, "and may stop[Pg 39] for the present." They agreed to call it quits, and resumed their study of the map. The river from Taku to Tien-tsin was crowded with junks and small boats, and it was easy to see that the empire of China has a large commerce on all its water-ways. The Grand Canal begins at Tien-tsin, and the city stands on an angle formed by the canal and the Pei-ho River. It is not far from a mile square, and has a wall surrounding it. Each of the four walls has a gate in the centre, and a wide street leads from this gate to the middle of the city, where there is a pagoda. The streets are wider than in most of the Chinese cities, and there is less danger of being knocked down by the pole of a sedan-chair, or of a coolie bearing a load of merchandise. In spite of its great commercial activity, the city does not appear very prosperous. Beggars are numerous, and wherever our friends went they were constantly importuned by men and women, who appeared to be in the severest want. "What sort of things," enquired the Doctor, slowly, as he listened to the Curate's heart. "You must make an effort to steady yourself." The best part of two days had passed, but there was no abatement in the sensation caused by the fresh tragedy of the corner house. An enterprising newspaper had made a determined effort to trace the whereabouts of the real owner of the premises and drag his pitiful story afresh into the daylight, but he was not to be found. No relative came forward with the hope of gain. And it looked as if the new tragedy was going to be as deep a mystery as the old one. "I will do anything I can to make your mind easy," Hetty said. When he had lifted the craft and headed for home, he glanced back. “If they had given up, so soon,” Dick mused, holding his head low to avoid the icy blast of their high position, “if they’d given up Jeff would go straight to the hangar again. But they’re going across Long Island Sound toward Connecticut, just as the unknown person in the hydroplane boat did with the other life preserver.” "You're a devil of a way from home, and in a bad neighborhood," said one of the men who had fired, as he slipped another cartridge into his Sharpe's. The next morning Holgrave received a peremptory order to attend at the castle in the afternoon; and the henchman of the baron, who was the bearer of the message, refused to give any information why he had been so summoned. Edith, with her natural penetration, saw, by the hesitation of the servitor, and by the tone in which the mandate was conveyed, that something of more than ordinary moment was about to be transacted, and, with an undefined feeling of alarm, she resolved to accompany her son. "By my faith, Holgrave, you seem to think lightly of this matter. Do you call it a scrape to commit a felony in your lord's chase? Have you any thing further to urge in your defence?"
