Hiding his canoe, still afloat, among these thickets, with its prow seaward, he sat down in the stern, paddle low in hand; and when the ship was gliding by, like a flash he darted out; gained her side; with one backward dash of his foot capsized and sank his canoe; climbed up the chains; and throwing himself at full length upon the deck, grappled a ringbolt there, and swore not to let it go, though hacked in pieces.
And if the second mate hap- pened to be there (he had generally one day in three free of fever) I would find him sitting on the skylight half senseless, as it were, and with an idiotic gaze fastened on some object near by--a rope, a cleat, a belaying pin, a ringbolt.
In eye and eye turnbuckle, yielding of loop can occur in heavy loading conditions, along with this shearing, stripping of threads of the ringbolts can also occur.
