we'd have to knock off for a week to let our hands get well--couldn't touch a case-knife with them sooner.” “Well, then, what we going to do, Tom?” “I'll tell you.  It ain't right, and it ain't moral, and I wouldn't like it to get out; but there ain't only just the one way:  we got to dig him out with the picks, and _let on_ it's case-knives.” “_Now_ you're _talking_!”  I says; “your head gets leveler and leveler all the time, Tom Sawyer,” I says. “Picks is the thing, moral or no moral; and as for me, I don't care shucks for the morality of it, nohow.  When I start in to steal a nigger, or a watermelon, or a Sunday-school book, I ain't no ways particular how it's done so it's done.  What I want is my nigger; or what I want is my watermelon; or what I want is my Sunday-school book; and if a pick's the handiest thing, that's the thing I'm a-going to dig that nigger or that watermelon or that Sunday-school book out with; and I don't give a dead rat what the authorities thinks about it nuther.” “Well,” he says, “there's excuse for picks and letting-on in a case like this; if it warn't so, I wouldn't approve of it, nor I wouldn't stand by and see the rules broke--because right is right, and wrong is wrong, and a body ain't got no business doing wrong when he ain't ignorant and knows better.  It might answer for _you_ to dig Jim out with a pick, _without_ any letting on, because you don't know no better; but it wouldn't for me, because I do know better.  Gimme a case-knife.” He had his own by him, but I handed him mine.  He flung it down, and says: “Gimme a _case-knife_.” I didn't know just what to do--but then I thought.  I scratched around amongst the old tools, and got a pickaxe and give it to him, and he took it and went to work, and never said a word. He was always just that particular.  Full of principle.
