Wheeler had his doubts about the competency of Bristol. The magnate wanted a suitable engineer, and would give him good wages. He might object to a man who had been known on the lake as nothing but a boatman. Peter wanted the place, and had been running an engine for two years. Wheeler agreed to do what he could for him with the magnate; but he thought it best for him not to say who he was for the present. Time and the tropical sun had so changed him that he was not likely to recognize him if he was careful. Peter Bristol had served as engineer on the way up, and Major Billcord and Walk had joined the vessel at Whitehall in the morning. The steamer was on trial, and the major wanted her run at her highest speed a part of the time. The magnate had hardly looked at the engineer, he was so interested in the machinery and the craft, and Bristol had had no trouble in concealing his identity so far. This was the story he told Paul, and repeated to his wife and Lily in the evening. Paul had looked out at the door and saw that the Undine was near Westport. She did not go to the shore, but when she came about and headed down the lake again, Peter Bristol turned the wheel and shut off the steam. There was a ringing of the bell, and then a call through the tube. "I shall run her no longer!" replied the engineer, emphatically, at the mouthpiece. Major Billcord came below, followed by Walk. Mr. Bristol stated his position, and took no further pains to conceal his identity. The father spoke to him like a man, and insisted upon being landed at Westport with his son. The magnate was taken all aback. He could do nothing without an engineer, and he could not punish Paul in the presence of his father. The engineer would take the steamer up to the wharf, but in no other direction. The magnate had to yield, and father and son, both the Bristol and the Billcord, landed. Lily was found, and she had a joyful meeting with her father. Bissell was very willing to loan his four-oar boat to convey them to Beech Hill. On the way they released Tom Topover, and, putting him into the Dragon, towed him back to Hornet Point. The happy re-union in the transplanted cottage need not be described. CHAPTER XXX. LAUNCHING THE BOAT. The Sylph, with the gundalow, did not arrive till it was nearly dark. The shoe was not done when the scow was ready to take it on board, and they had to wait for the workmen to drill the holes for the bolts. The ship's company had seen the Undine when she passed Port Henry, but no one there knew to whom she belonged, or anything whatever in regard to her. They saw that she was the counterpart of the Sylph, and knew that she was one of the celebrated class to which she belonged. Some of the students thought there might be a chance for a race between her and the Beech Hill steamer; but Dory was sure enough that Captain Gildrock would not permit the Sylph to race with anything that went by steam.
