These sweeps were immensely large oars, each requiring a couple of men to work it.

In a few minutes we entered the mouth of the creek, which was indeed the mouth of a small river, and took about half an hour to ascend it, although the spot where we intended to land was not more than six hundred yards from the mouth, because there was a slight current against us, and the mangroves which narrowed the creek, impeded the rowers in some places.
Having reached the spot, which was so darkened by overhanging trees that we could see with difficulty, a small kedge anchor attached to a thin line was let softly down over the stern.
"Now, lads," whispered the captain, as he walked along the line of men, who were all armed to the teeth, "don't be in a hurry, aim low, and don't waste your first shots." He then pointed to the boat, into which the men crowded in silence.

There was no room to row, but oars were not needed, as a slight push against the side of the schooner sent the boat gliding to the shore.
"There's no need of leaving two in the boat," whispered the mate, as the men stepped out; "we shall want all our hands.

Let Ralph stay." The captain assented, and ordered me to stand in readiness with the boat- hook, to shove ashore at a moment's notice if they should return, or to shove off if any of the savages should happen to approach.

He then threw his carbine into the hollow of his arm and glided through the bushes followed by his men.
