“Well, now, would it be?” asked the Tough Customer. “How about this arrow? This arrow points right to where the road crosses the creek. Don’t that mean that that is where the treasure is? Suppose there is a bridge there, or a culvert. Mightn’t the money be hid there? Well, we could look both places. How about this ‘23 miles’ and ‘Greenland’?” “Greenland? Sure enough, that says Greenland!” said the Rat, all excited. “Why, pardner, this is the easiest thing you ever saw! I know where this Greenland is--Greenland is a crossroads store up the river four or five miles from here, over on the Illinois side, just on top of the hills. Used to be quite a village, years ago, but it’s only a store and post-office now. Why, I can take you right there, pardner. And there’s a creek there, too, crosses the road. Only-- “Greenland ain’t any 23 miles back from the slough, or from the river, either. It’s only--say!” The boys heard him slap his knee. “Why, shucks!” he exclaimed. “That ain’t 23 miles. That’s meant for two-three miles. Two _or_ three miles. And that’s about what this Greenland store is back from the river.” He let his voice fall into a mysterious whisper. “Why, pardner,” he whispered, “this is as easy as falling off a log! We can walk right to the spot. And that arrow don’t point to no treasure, either. That arrow is like any other arrow on a map--it points north. It was put there to show where north is.” “But that would make the Mississippi River flow from east to west,” objected the Tough Customer. “And that’s why I say so!” declared the Rat. “Because it does flow right spang from east to west, all the way from Derlingport to Riverbank--thirty good miles! If that map showed a river flowing from north to south, it would be wrong, because the Mississippi don’t flow that way at Greenland store. You bet! All we’ve got to do is to go right to the bank of the creek where that cross-mark is, and if that treasure is there, we’ll find her!” “So you’ll put off cider-hunting awhile, I guess,” said the Tough Customer. “Gimme the map; I’ll put it back where I keep it.” He shuffled around inside the boat, putting the map back. “Well, now,” the Rat said, “as to putting off hunting that cider, it seems to me, seeing we’re right here on the island, we might take a day or two and--”
