Asgeelo—or Cato, as Brandon commonly called him—had made those simple preparations which are common among his class—the apparatus which the pearl-divers have used ever since pearl-diving first commenced. Twelve or fifteen stones were in the boat, a flask of oil, and a sponge which was fastened around his neck. These were all that he required. Each stone weighed about thirty pounds. One of these he tied around one foot; he saturated the sponge with oil, so as to use it to inhale air beneath the water; and then, standing on the edge of the boat and flinging his arms straight up over his head, he leaped into the water and went down feet foremost.
Over the smooth water the ripples flowed from the spot where Asgeelo had disappeared, extending in successive concentric circles, and radiating in long undulations far and wide. Louis and Frank waited in deep suspense. Asgeelo remained long beneath the water, but to them the time seemed frightful in its duration. Profound anxiety began to mingle with the suspense, for fear lest the faithful servant in his devotion had over-rated his powers—lest the disuse of his early practice had weakened his skill—lest the weight bound to his foot had dragged him down and kept him there forever.
At last, when the suspense had become intolerable and the two had already begun to exchange glances almost of despair, a plash was heard, and Asgeelo emerged far to the right. He struck out strongly toward the boat, which was at once rowed toward him. In a few minutes he was taken in. He did not appear to be much exhausted.
He had seen nothing.

They then rowed about a hundred yards further, and Asgeelo prepared to descend once more. He squeezed the oil out of the sponge and renewed it again. But this time he took a knife in his hand.
“What is that for?” asked Frank and Louis.
“Sharks!” answered Cato, in a terrible tone.
At this Louis and Frank exchanged glances. Could they let this devoted servant thus tempt so terrible a death?
“Did you see any sharks?” asked Louis.
