He succeeded very quickly in reaching the door, when, loosening one of the chains from his ankle, he made every exertion to force the passage with it, but in vain, the framework of the room being far stronger than was anticipated. He was quite exhausted with his long stay under water, and it became absolutely necessary that some other one of us should take his place. For this service Parker immediately volunteered; but, after making three ineffectual efforts, found that he could never even succeed in getting near the door. The condition of Augustus’s wounded arm rendered it useless for him to attempt going down, as he would be unable to force the room open should he reach it, and it accordingly now devolved upon me to exert myself for our common deliverance. Peters had left one of the chains in the passage, and I found, upon plunging in, that I had not sufficient balance to keep me firmly down. I determined, therefore, to attempt no more, in my first effort, than merely to recover the other chain. In groping along the floor of the passage for this, I felt a hard substance, which I immediately grasped, not having time to ascertain what it was, but returning and ascending instantly to the surface. The prize proved to be a bottle, and our joy may be conceived when I say that it was found to be full of port wine. Giving thanks to God for this timely and cheering assistance, we immediately drew the cork with my penknife, and, each taking a moderate sup, felt the most indescribable comfort from the warmth, strength, and spirits with which it inspired us. We then carefully recorked the bottle, and, by means of a handkerchief, swung it in such a manner that there was no possibility of its getting broken. Having rested a while after this fortunate discovery, I again descended, and now recovered the chain, with which I instantly came up. I then fastened it on and went down for the third time, when I became fully satisfied that no exertions whatever, in that situation, would enable me to force open the door of the storeroom. I therefore returned in despair.
