"It would be a very risky thing, Bob," Captain Lockett said, shaking his head. "I shouldn't like to let you do it; though of course it would be a great thing, if we could learn something about her. I own I don't like her appearance, though I can't say why. Somehow or other, I don't think she is all right. Either all those guns are a mere pretence, and she is weak handed, or she must carry a very big crew."
"Well, I don't see there can be any possible harm in my trying to get on board her, captain. Of course, if I am hailed as I approach her, I shall turn and come back again. The night will be dark, but I shall have no difficulty in finding her, from the talking and noise on board.
"Well, Joe, what do you think?" the captain said, doubtfully.
"I think you might let Bob try," Joe said. "I should not mind trying at all but, as I can't speak Spanish, I should be able to learn nothing. They are not likely to be setting a watch, and keeping a sharp lookout, for some time; and I should think that he might, possibly, get on board unobserved. If they do make him out, he has only to keep on diving and, in the dark, there would be little chance of their hitting him. Besides, they certainly couldn't make out that it was a swimmer. If they noticed a ripple in the water, they would be sure to think it was a fish of some sort."
Bob continued to urge that he should be allowed to try it and, at last, Captain Lockett agreed to his doing so. It was already almost dark enough for the attempt to be made, and Bob prepared at once for the swim. He took off his coat, waistcoat, and shirt; and put on a dark knitted jersey, fastened a belt tightly round his waist, over his breeches, and took off his shoes.
"If I am seen," he said, "you are sure to hear them hailing, or shouting; and then please show a lantern over the stern," for, slight as the current was, it sufficed to make the vessel swing head to west.
A rope was lowered over the side and, by this, he slipped down quietly into the water, which was perfectly warm. Then he struck off noiselessly, in the direction of the ship. He kept the two masts of the brig in one, as long as he could make them out but, owing to the mist on the water, he soon lost sight of her; but he had no difficulty in keeping a straight course, as he could plainly hear the sound of voices, ahead of him. Taking the greatest pains to avoid making the slightest splash, and often pausing to listen, Bob swam on until he saw a dark mass looming up in front of him.
He now did little more than float, giving a gentle stroke, occasionally, and drifting towards it until he grasped the cable.
