Upon emerging from the entrance to the cave, after having first taken a most careful look round, I made my way, with much circumspection, to the crown of a high knoll or ness, jutting out a little way into the bay, from which I believed I should be able to get a good view of the "yard", and ascertain, in the first instance, what might be happening in that direction.  The crest of this knoll was crowned with a thick and tolerably extensive clump of bushes, screened by which I hoped to be able both to see and hear anything that might happen to be transpiring among the various sheds, and at the same time to keep an eye upon the brig where she lay at her buoy, about half a mile from the shore.  When, however, I reached my hiding place I was disappointed to find that I was considerably farther away from the wharf and the buildings than I had expected; and that while I could see pretty well what was happening down there, as well as command an excellent view of the brig, I could hear nothing save an occasional shout; and it was even more upon what I should hear than upon what I should see that I depended for the necessary information upon which to base my plans.  But there was a spot at some distance down the front of the slope which I thought would suit my purpose admirably if I could only reach it without being seen, and I at once determined to make the attempt.  It was a somewhat peculiarly shaped outcrop of rock with a hollow in the middle of it, and I believed that if I could but gain its shelter without discovery I should be able to see from it nearly as well as from where I was, while I should certainly be able to hear very much better.  The only question was how to get there.  And after very carefully examining my surroundings from the shelter of my screen of bushes I came to the conclusion that my only plan would be to descend to the beach again by the way that I had come, enter the wood as though I intended to return to the house, and skirt it until I came very nearly to its far end, when, by concealing myself in a thick and extensive bed of ferns, I might reasonably hope to gain the desired spot without any very great difficulty or danger.  Accordingly, having first carefully looked about me to assure myself that I need not fear being seen, I cautiously emerged from my hiding place, and as cautiously made my way down to the beach again, from which it was easy to gain the shelter and concealment of the wood.  Another ten minutes found me, heedless of the danger of snake bites, painfully wriggling my way through the bed of ferns, lifting my head above the fronds occasionally to make sure that I was steering a straight course; and twenty minutes later saw me safely ensconced in my hiding place, from which I could both see and hear distinctly without being seen.
