We had a merry laugh over the situation when suddenly the tables were turned. Something whizzed past Bill’s ear; I was stung on the arm with a heavy nail; a large stone hit the scow; Reddy had his hat knocked off, and Fred upset his canoe trying to duck out of reach of the invisible missiles before we could make our assailants understand that we were friends and not the tramps. The joke was on us after all. We hadn’t counted on Dutchy’s accurate aim or Jack’s skill with the crossbow.
Tramp-proof Boat Mooring.
Fig. 146. A Tramp-proof Mooring.
Around the camp fire that night we discussed our adventures and made plans to prevent their recurrence. It was evident, for one thing, that we would have to moor our boats off shore in such a way that they would be out of reach of meddlesome persons, and yet could be drawn in toward shore by any one who knew how. This was the way we did it. A pair of galvanized iron ring bolts were procured on Jack’s next trip to Lamington for provisions, also a light rope about forty feet long. The ring bolts were screwed into a pair of stout anchor stakes about two feet from their lower ends. The rope was passed through the rings and the ends were joined by tying them to a galvanized iron link. Then it was soaked for a while to shrink it before it was set in place. After the rope had shrunk sufficiently, the two stakes were driven into the bed of the river, one close to the bank and the other far enough out to hold the rope belt clear of the bottom. Both stakes were sawed off under water, just above the ring bolts, so that they were hidden from sight. When we wanted to moor our boats we secured their anchor ropes or “painters” to the link. A large stepping stone marked the spot were the inner stake was driven, and standing on this stone we were able to reach down and haul in on the lower strap of the belt to draw the boat out a safe distance from shore, and then when we wanted to use our boat again we would haul in the upper strap to draw the boat in toward shore.
CHAPTER XIII.
WIGWAGGING AND HELIOGRAPHING.
Our tramp adventure was really quite a blessing to us, for it taught us the necessity of a good signaling system between the Goblins’ Platform and the island and led to our learning how to wigwag, and later to the construction of a heliograph. Uncle Ed, when he read of our experience, sent us the U. S. Army “Manual of Signaling.” Fred, the tailor of our camp, made us two white flags with red centers. Each flag was two feet square and was fastened to a light staff about five feet long. Then we got out the manual and practised sending signals, at first within shouting distance, until we got to be quite expert.
