Brave Old Salt by Oliver Optic

At general quarters, on the following day, Somers looked somewhat care-worn. It was midnight when he had worked out the solution of the cipher, and at this hour he had been called to take the mid watch. But there was no happier or more exultant man in the fleet. His conquest over the cabalistic letter had confirmed his theory. The Ben Lomond was not a myth, and she was at Mobile. Pillgrim had expressed a desire to see Somers again, and there was a fair prospect that he might yet be able to do so.

The important event of this day was the dinner with "Brave Old Salt. " But the letter and the dinner seemed to be inseparably connected. Somers had given the translation to the first lieutenant, who, to the chagrin and mortification of the persevering student, did not appear to attach much importance to the letter.
