It came on with extreme caution. The oars fell at considerable intervals. One of the convicts seated in front had a sounding-line in his hand, with which he was feeling for the increased depth of water caused by the current of the Mercy. This indicated Harvey’s intention of bringing his brig as near shore as possible. About thirty pirates were scattered among the shrouds watching the boat and noting certain sea-marks which would enable them to land without danger. The boat was but two cables’ length from the islet when it stopped. The helmsman, standing erect, was trying to find the best place to land. In a moment burst forth a double flash and report. The helmsman and the man with the line fell over into the boat. Ayrton and Pencroff had done their work. Almost at once came a puff of smoke from the brig, and a cannon ball struck the rock, at whose foot the two lay sheltered, making it fly into shivers; but the marksmen remained unhurt. With horrible imprecations the boat resumed its course. The helmsman was replaced by one of his comrades, and the crew bent to their oars, eager to get beyond reach of bullets. Instead of turning back, they pulled for the southern extremity of the islet, evidently with the intention of coming up on the other side and putting Pencroff and Ayrton between two fires. A quarter of an hour passed thus without a sound. The defenders of the islet, though they understood the object of the flanking movement, did not leave their post. They feared the cannon of the Speedy, and counted upon their comrades in ambush. Twenty minutes after the first shots, the boat was less than two cables’ length off the Mercy. The tide was running up stream with its customary swiftness, due to the narrowness of the river, and the convicts had to row hard to keep themselves in the middle of the channel. But as they were passing within easy range of the river’s mouth, two reports were heard, and two of the crew fell back into the boat. Neb and Spilett had not missed their shot. The brig opened fire upon their hiding place, which was indicated by the puff of smoke; but with no result beyond shivering a few rocks. The boat now contained only three men fit for action. Getting into the current, it shot up the channel like an arrow, passed Smith and Herbert, who feared to waste a shot upon it, and turned the northern point of the islet, whence the two remaining oarsmen pulled across to the brig. So far the colonists could not complain. Their adversaries had lost the first point in the game. Four pirates had been grievously wounded, perhaps killed, while they were without a scratch. Moreover, from the skilful disposition of their little force, it had no doubt given the impression of a much greater number.
