Deane possessed an iron frame, but the anxiety which he endured began to tell greatly upon him, and for the first time in his life, he felt that he was becoming seriously ill. The thought occurred to him that it might be the yellow fever. Every day he grew worse and worse. His head ached, his limbs were full of pains, still he kept up his spirits as well as he could, and he and his companions continued to entertain hopes of escaping. One night Burridge returned from his usual expedition in high spirits. He had important information to give. While wandering along the shore he came suddenly upon a person seated on a rock, apparently watching the harbour as he had been. At first he felt very nervous about approaching the man, doubting who he could be. Still it struck him that it was not likely to be one of the pirates. He therefore cautiously approached him and, in a low voice, asked him who he was. "You may suppose, sir," said Burridge, "when he gave me the account my heart did leap with joy, when I found that he was an old shipmate--the pilot of a vessel I once sailed in! And what was more curious, he has been thinking of the same thing that we have, and hoping to make his escape in the same manner. He tells me that he has two companions on the island who are kept at work by the pirates as slaves; but that he has had an opportunity of speaking to them, and that they're ready to help him make off with a vessel. If I had not known him, I should have been afraid of treachery; but he is a true man, and we need have no fear on that score. There will be moon enough for our purpose about five days hence, and I've arranged that we should all meet him at the spot where I found him at midnight at that time." This information raised Jack's spirits, which had become very low in consequence of his illness. The effect, however, was only temporary, for the following day he became worse, and his companions began to fear that he would be taken from them. Their daily visitor, as it happened, remained in the hut longer than usual, and had thus an opportunity of observing how ill Deane looked. The midshipmen and Burridge also told him that they were afraid their officer would die if he had not some help. "True enough, master," said the man. "I will tell our captain, and perhaps he will do something for him. We have no objection to killing men in fair fight; but it is not our way to put them out of the world by clapping them into prisons, as they do in some countries." Saying this the man took his departure, promising to inform his captain of Deane's state of health.
