Bob, who had been so intently watching the men that he had not looked round at the sky, since they first went aloft, now had time to do so; and was startled with the change that had come over the sea, and sky. There was not a breath of wind. There was a dull, oily look on the water, as it heaved in long, regular waves, unbroken by the slightest ripple. Black clouds had banked up from the southwest, and extended in a heavy arch across the sky, but little ahead of the brig. From its edge ragged, fragments seemed to break off suddenly, and fly out ahead. "It is going to blow, and no mistake," the captain said. "It is lucky that we have had plenty of time to get her into fighting trim. "You had better get hold of something, lad, and clutch it tight. It will begin with a heavy squall and, like enough, lay her pretty well over on her beam ends, when it strikes her." Higher and higher the threatening arch rose, till its edge stood over the mainmast. Then the captain cried: "Here it comes, lads. Hold on, every one!" Looking ahead, Bob saw a white line. It approached with wonderful rapidity, and with a confused, rushing sound. Then in a moment he felt himself clinging, as if for life, to the stanchion of which he had taken hold. The wind almost wrenched him from his feet while, at the same moment, a perfect deluge of water came down upon him. He felt the brig going further and further over, till the deck beneath his feet seemed almost perpendicular. The captain and first mate had both grasped the spokes of the wheel, and were aiding the helmsman in jamming it down. Bob had no longer a hold for his feet, and was hanging by his arms. Looking down, the sea seemed almost beneath him but, with a desperate effort, he got hold of the rail with one hand, and then hauled himself up under it, clinging tight to the main shrouds. Then he saw the second mate loose the jib halliards, while one of the sailors threw off the fore-staysail sheet, and the spanker slowly brought the brig's head up into the wind. As it did so she righted, gradually, and Bob regained his place on deck; which was still, however, lying over at a very considerable angle. The captain raised his hand, and pointed to the main topsail; and the second mate at once made his way aft with some of the men and, laying out on the weather rigging, made his way aloft. The danger seemed, to Bob, so frightful that he dared not look up. He could hear, through the pauses of the blast, the mate shout to the men above him and, in a few minutes, they again descended to the deck. Even Bob could feel how much the brig was relieved, when the pressure of the topsail was taken off. The lower planks of the deck rose from the water and, although this still rushed in and out through the scupper holes, and rose at times to the level of the bulwark rail, he felt that the worst was over. One of the men was called to assist at the helm, and the captain and mate came forward to the poop rail.
