Pillgrim began to storm again, shouted to the pilot to stop the steamer, and behaved in the most violent manner. Mr. Swayne's patience was totally exhausted, and he ordered the seamen who stood near him to arrest the interloper. A sharp struggle ensued, in which Pillgrim was overpowered, and was held fast by the stout tars of the Chatauqua. The first lieutenant then explained to the captain what had passed, and what he had done. "Put him in irons!" said Somers, decidedly. "Who is he, captain?" "It matters not who he is. No man can behave in that manner on board of this ship." Swayne executed his orders to the letter, and the traitor, in spite of his struggles, in spite of his explanations and appeals, was put in irons on the quarter deck of his own ship. He was carried below, and put in a state-room, which was guarded by Conant, who had orders to shoot him if he did not keep quiet. In the mean time, the Ben Lomond,--for Somers, in strict accordance with the subsequent "ruling" of Mr. Seward, refused to recognize the vessel by any other than her original name, calling her the Tallapoosa only in the presence of the rebels,--the Ben Lomond, under the skilful guidance of the pilot, was slowly making her way out of the bay. A quartermaster had been stationed in the fore-chains when the steamer got under way, to take the soundings, which seemed to be the pilot's principal reliance in the difficult duty he had undertaken. Captain Column had placed himself on the port rail, just abaft the foremast, and the steering directions were sent aft through a line of officers to the helmsman. "By the deep four," sang the quartermaster in the chains. "Steady!" said the pilot. "Keep her sou'-west by west, half west." "Steady!" responded the quartermaster at the wheel. "Sou'-west by west, half west." "By the mark five!" said the leadsman, a little later. "We are getting into deep water," said Somers. "Yes, sir; we shall deepen till we get seven fathoms." "And a half five!" came from the chains. "By the deep six." The pilot went on the bridge, and taking the cord attached to the whistle of the engine, made a signal, consisting of several blasts, with irregular intervals between them. A heavy bell on shore sounded several times in answer to the signal. "All right," said the pilot. "I know exactly where I am." "By the deep six!" called the leadsman. The pilot repeated the signal with the whistle, which was answered from the shore by the bell. "Quarter less seven!" "It is all going right, captain," said the pilot to Somers, who stood on the bridge with him. "By the mark seven!" "Hard a port!" shouted the pilot, as he gazed into the binnacle on the bridge. "Hard a port!" repeated the line of officers, till the order was returned by the wheelman. "Steady!" said the pilot. "Mark under water seven!" cried the quartermaster in the chains. "Keep her south by west," added the pilot. "South by west!" returned the wheelman.
