CHAPTER XVI ABOUT noon the next day the boys arrived at the dead tree; they had come for their tools. Tom was impatient to go to the haunted house; Huck was measurably so, also—but suddenly said: "Lookyhere, Tom, do you know what day it is?" Tom mentally ran over the days of the week, and then quickly lifted his eyes with a startled look in them— "My! I never once thought of it, Huck!" "Well, I didn't neither, but all at once it popped onto me that it was Friday." "Blame it, a body can't be too careful, Huck. We might 'a' got into an awful scrape, tackling such a thing on a Friday." "MIGHT! Better say we WOULD! There's some lucky days, maybe, but Friday ain't." "Any fool knows that. I don't reckon YOU was the first that found it out, Huck." "Well, I never said I was, did I? And Friday ain't all, neither. I had a rotten bad dream last night—dreampt about rats." "No! Sure sign of trouble. Did they fight?" "No." "Well, that's good, Huck. When they don't fight it's only a sign that there's trouble around, you know. All we got to do is to look mighty sharp and keep out of it. We'll drop this thing for today, and play. Do you know Robin Hood, Huck?" "No. Who's Robin Hood?" "Why, he was one of the greatest men that was ever in England—and the best. He was a robber."
