here they will be interrupted, but our movement continuing and fresh vibrations passing on, at last the accumulated force is transmitted to the top with a multiple of power beyond our calculation. Again, suppose the vibration or waves to have reached the extreme end of the rod, it by no

that is, the top dips before it rises ; it dips, I say, and before it rises, of course, other vibrations have been succeeding have now reached; and at last, with great force, the top flips up, suddenly pulling with an unintentioned jerk upon the line, and the But again, fish, which will probably be lost. we have only now considered the efi'ect produced on the fish when thus powerfully struck, but let us retrace our steps, for having struck and having set a rod thus in vibrations, we have another effect produced, a new series of vibrations will be sent from the top downwards towards the butt ; nor, as yet, has the first force exerted been vibrations still continue lost on the butt ; no

from this direction, and as we now have two sets of vibrations set up at opposite ends, the only question which reinains is where will these meet ? the answer will be, in practice, speedily discovered it will be at that part of the rod which we called the point of interruption, where the second action commenced, owing to the too extended length of the part disproportionally with its tapering, and the effect of the concurrence, or
