Without explaining my purpose, I got a large cast-iron mortar, filled it with gunpowder, secured a block of oak to the top, through which I pierced a hole for the insertion of the match, and this great petard I so placed, that when it exploded it should blow out the side of the vessel next from which the pinnace lay. Then securing it with chains, that the recoil might do no damage, I told the boys I was going ashore earlier than usual, and calmly desired them to get into the boat. Then lighting a match I had prepared, and which would burn some time before reaching the powder, I hastened after them with a beating heart, and we made for the land. We brought the raft close in shore and began to unload it; the other boat I did not haul up, but kept her ready to put off at a moment's notice; my anxiety was unobserved by anyone, as I listened with strained nerves for the expected sound. It came!--a flash! a mighty roar--a grand burst of smoke! My wife and children, terror-stricken, turned their eyes toward the sea, whence the startling noise came, and then, in fear and wonder, looked to me for some explanation. "Perhaps," said the mother, as I did not speak, "perhaps you have left a light burning near some of the gunpowder, and an explosion has taken place." "Not at all unlikely," replied I quietly; "we had a fire below when we were caulking the seams of the pinnace. I shall go off at once and see what has happened. Will any one come?" The boys needed no second invitation, but sprang into the boat, while I lingered to reassure my wife by whispering a few words of explanation, and then joining them, we pulled for the wreck at a more rapid rate than we ever had done before. No alternation had taken place in the side at which we usually boarded her, and we pulled round to the further side, where a marvelous sight awaited us. A huge rent appeared, the decks and bulwarks were torn open, the water was covered with floating wreckage--all seemed in ruins; and the compartment where the pinnace rested was fully revealed to view. There sat the little beauty, to all appearance uninjured; and the boys, whose attention was taken up with the melancholy scene of ruin and confusion around them, were astonished to hear me shout in enthusiastic delight: "Hurrah! she is ours! The lovely pinnace is won! we shall be able to launch her easily after all. Come, boys, let us see if she has suffered from the explosion which has set her free." The boys gazed at me for a moment, and then guessing my secret, "You planned it yourself, you clever, cunning father! Oh, that machine we helped to make was on purpose to blow it up!" cried they; and eagerly they followed me into the shattered opening, where, to my intense satisfaction, I found everything as I could wish, and the captive in no way a sufferer from the violent measures I had adopted for her deliverance.
