I lay down with infinite pleasure, and swallowed a most cheering draught of the precious liquid; and, sitting on the brink, made a good meal of what I had with me, and then drank again. I had now got five-sixths of the lake's circumference to go back again to my boat, for I did not suspect any passage over the cavern's mouth where I came into the lake; and I could not, without much trouble, consider that, if I would have this water for a constant supply, I must either come a long way for it, or fix my habitation near it. I was just going back again, revolving these uneasy thoughts in my breast, when this rose suddenly in my mind, that, if I could possibly get over the mouth of the cavern, I should not have above three miles from my grotto to the water. Now, as I could not get home that night otherwise than by crossing it, and as, if I lost my labour, I should be but where I was, whereas if I should get over it, it would very much shorten my journey, I resolved to try whether the thing was practicable, first, however, looking out for a resting-place somewhere near my water, if I should meet with a disappointment. I then walked into the wood, where, meeting with no place of retreat to my liking, I went to my rill, and taking another sup, determined not to leave that side of the lake till morning; but having some time to spare, I walked about two miles to view the inlet of the lake, and was agreeably surprised, just over the mouth of the cavern, to see a large stone arch like a bridge, as if it had been cut out of the rock, quite across the opening: this cheered me vastly, and, pushing over it, I found a path that brought me to my boat before night. I then went up to my grotto for the third night in this most delightful place; and the next morning early I launched my boat, and taking my water-cask and a small dipping bucket with me, I rowed away for the rill, and returned highly pleased with a sufficiency of water, whereof I carried a bucket and a copper kettle full up with me to the grotto. Indeed, it was not the least part of my satisfaction that I had this kettle with me; for though I was in hopes, in my last voyage, I should have come to some shore, where I could have landed and enjoyed myself over some of my fish, and for that reason had taken it, notwithstanding things did not turn out just as I had schemed, yet my kettle proved the most useful piece of furniture I had.
