"But if those chaps have gone ahead, what's the use?" demanded Nat.
"Because, don't you see," put in Toby, anxious to air his knowledge, "what's going to hinder them lying in wait, and jumping out on Lil Artha. Shall we keep tabs of the left side as before, Elmer?"
"The left—yes; but I imagine we're going to come upon our chum mighty soon now. That track was fresh, and I've an idea it wasn't made more than ten minutes ago, at the most fifteen."
Both the other lads looked admiringly at the one who was able so confidently to say such a positive thing. They could not imagine how it was done; and as their glances met they shook their heads, as though condoling with each other on their mutual ignorance.
Then pop-pop-pop, and they were all off in a line, with Nat, as usual bringing up the rear, and Elmer in the van.
Ahead of them, about half a mile away, there seemed to be some sort of a bend; although the shadows played around the spot so densely that even the sharp eyesight of Elmer failed to make sure just what sort of a curve the road took there.
He had what he called a "hunch" that once around this they would be apt to sight the one in whose fortunes they were so vitally interested. So away they tore, letting the engines out for all they were worth; and Nat, as before, utterly ignoring the fact that he had a muffler connected with his metal steed.
And as Elmer whirled around the curve he looked eagerly ahead. At first he saw nothing save a long stretch of road that seemed to mellow as it dropped a little in the distance. Was it possible that Lil Artha could have passed beyond the extreme limit of observation? If so, then the deduction he had made as to the length of time elapsing since that footprint was made could not have been the true one.
Ah, what was that moving there under the trees about half a mile ahead, and just before the road took its slight downward pitch? Surely he had seen something rise and fall with regularity; and it could hardly be a branch.
The object caught his eye again. It was red, and Elmer suddenly remembered that Lil Artha always made it a point to carry a couple of big red bandana handkerchiefs along with him when about to indulge in any game, whether baseball, football or a fishing excursion that entailed a long walk.
