To assist his design he drew maps and charts of the coast from memory, and was not satisfied till he could make a perfect diagram of the coast, shoals, islands, and bars, mark the prominent objects to be sighted from a vessel, and lay down the depth of water. He had nothing else to do on the passage; and as the steamer glided swiftly over the summer sea, he found it a more agreeable occupation than smoking, playing cards, and "spinning yarns," which were the employments of his fellow-passengers. On the eighth day from Fortress Monroe the supply steamer reached the blockading fleet off Mobile Bay, and Somers was warmly welcomed by his brother officers. Of course he had a long story to tell, which was listened to with interest. The escape of the late second lieutenant was received with becoming indignation. Somers was now the third lieutenant of the Chatauqua, and he moved into the state-room formerly occupied by Mr. Garboard, who had also advanced one grade in his relative rank. "Somers, you are just in time for a big thing," said Mr. Hackleford. "Our Brave Old Salt is going to take us up Mobile Bay in a few days." "Indeed?" "Yes, the Old Salamander has issued his orders." "God bless him!" ejaculated Somers, fervently, in much the same spirit that a loyal subject speaks of a popular monarch. "Ay, God bless him!" replied the first lieutenant. "He is the ablest naval commander the world has yet produced. In my opinion he is the superior of Nelson, Collingwood, Decatur, Porter, Preble, and Hull. By the way, Mr. Somers, you were with him on the Mississippi?" "Yes, sir; I was in the Harrisburg when the fleet passed Forts Jackson and St. Philip. But I am rather sorry the attack is to take place so soon." "Why so?" Then Somers showed him Pillgrim's letter; but as we intend to tell only what was done, not what was said, we will not record the conversation. CHAPTER XVIII. BRAVE OLD SALT. The most extensive and careful preparations were in progress for the events which, a few days later, astonished the world even more than the splendid achievements of the fleet below New Orleans. The squadron off the mouth of Mobile Bay had been actively employed for several days in sending down top-masts, superfluous spars, and rigging. Chain cables had been extended over the sides of the ships where the machinery was exposed to injury from the shot and shell of the fort. Chains and sand bags were placed on the decks where plunging shot might disable the engines. Boats were removed from the starboard to the port sides, for the fleet was to go in with Fort Morgan on the right, and close aboard of them.
