Passage 241
“We've been pretty good friends, you and me, Mr. Dodd,” he resumed. “We've been going through the kind of thing that tries a man. We've had the hardest kind of work, we've been badly backed, and now we're badly beaten. And we've fetched through without a word of disagreement. I don't say this to praise myself: it's my trade; it's what I'm paid for, and trained for, and brought up to. But it was another thing for you; it was all new to you; and it did me good to see you stand right up to it and swing right into it—day in, day out. And then see how you've taken this disappointment, when everybody knows you must have been tautened up to shying-point! I wish you'd let me tell you, Mr. Dodd, that you've stood out mighty manly and handsomely in all this business, and made every one like you and admire you. And I wish you'd let me tell you, besides, that I've taken this wreck business as much to heart as you have; something kind of rises in my throat when I think we're beaten; and if I thought waiting would do it, I would stick on this reef until we starved.”
I tried in vain to thank him for these generous words, but he was beforehand with me in a moment.
“I didn't bring you ashore to sound my praises,” he interrupted. “We understand one another now, that's all; and I guess you can trust me. What I wished to speak about is more important, and it's got to be faced. What are we to do about the Flying Scud and the dime novel?”
I don't exactly understand this wording. I've looked it up in the dictionaries and I think it has something to do with 'self-praise' but I could be wrong. What exactly does . . . to sound my praises mean in this context?
