He felt that the water washed his feet, and with a sort of instinct he rose, and staggered up to windward.

In so doing, without perceiving him, he stumbled over the body of Newton, who also was roused up by the shock.

A few moments passed before either could regain his scattered senses; and, at the same time, both sitting up on the deck, at about a yard distant, they discovered and recognised each other.
Newton was the more collected of the two, for Jackson's insensibility had been occasioned by bodily--his, by mental concussion.

The sight of Newton went far to recover Jackson, who started up as if to grapple with the object of his hatred.

Newton was on his legs at the same moment, and retreating, seized upon the handspike, which lay on the deck, close to where Jackson had been struck down, and placed himself in an attitude of defence.
