1853  (1892)  Each man had his own shoulder-belt, or "rue-raddy," as we used to call it, and his own track-line, which, for want of horse-hair, was made of manilla rope; it traversed freely by a ring on a loop or bridle, that extended from runner to runner in front of the sledge.
1938  Gone are the trackers, coiled are the track-lines.
1947  The left-hand sketch shows two 40-foot York boats being hauled up-river by track-lines.
1963  I picked up the trackline--a hundred feet of light line, one end fastened to the ring in the bow, the other to the rear seat. We shoved the canoe out on it and I started to steer it with the line down the riffle.
