Hank's expertise

I am an American.  I was born and reared in Hartford, in the State of Connecticut—anyway, just over the river, in the country.  So I am a Yankee of the Yankees—and practical; yes, and nearly barren of sentiment, I suppose—or poetry, in other words.  My father was a blacksmith, my uncle was a horse doctor, and I was both, along at first.  Then I went over to the great arms factory and learned my real trade; learned all there was to it; learned to make everything:  guns, revolvers, cannon, boilers, engines, all sorts of labor-saving machinery.  Why, I could make anything a body wanted—anything in the world, it didn’t make any difference what; and if there wasn’t any quick new-fangled way to make a thing, I could invent one—and do it as easy as rolling off a log.  I became head superintendent; had a couple of thousand men under me.
