“Upon this discovery I was so sanguine as to consider the enigma solved; for the phrase ‘main branch, seventh limb, east side,’ could refer only to the position of the skull upon the tree, while ‘shoot from the left eye of the death’s-head’ admitted, also, of but one interpretation, in regard to a search for buried treasure. I perceived that the design was to drop a bullet from the left eye of the skull, and that a beeline, or, in other words, a straight line, drawn from the nearest point of the trunk through ‘the shot,’ (or the spot where the bullet fell,) and thence extended to a distance of fifty feet, would indicate a definite point—and beneath this point I thought it at least possible that a deposit of value lay concealed.”
“All this,” I said, “is exceedingly clear, and, although ingenious, still simple and explicit. When you left the Bishop’s Hotel, what then?”
“Why, having carefully taken the bearings of the tree, I turned homewards. The instant that I left ‘the devil’s seat,’ however, the circular rift vanished; nor could I get a glimpse of it afterwards, turn as I would. What seems to me the chief ingenuity in this whole business, is the fact (for repeated experiment has convinced me it is a fact) that the circular opening in question is visible from no other attainable point of view than that afforded by the narrow ledge upon the face of the rock.
“In this expedition to the ‘Bishop’s Hotel’ I had been attended by Jupiter, who had, no doubt, observed, for some weeks past, the abstraction of my demeanor, and took especial care not to leave me alone. But, on the next day, getting up very early, I contrived to give him the slip, and went into the hills in search of the tree. After much toil I found it. When I came home at night my valet proposed to give me a flogging. With the rest of the adventure I believe you are as well acquainted as myself.”
