What he found could scarcely be said to do those anticipations justice; it was neither a casket of precious stones, nor a document establishing the family right of ownership of the whole county of Sussex. It was nothing more than a tarnished rod of silver, about nine inches in length, and twisted into an irregular sort of corkscrew shape. One end terminated in a broad flat button; the other in a blunted point. There was nothing else in the hole--nothing to show what the rod was meant for, or why it was so ingeniously hidden there. And yet, reflected Archibald, could it have been so hidden, and its place of concealment so mysteriously indicated, without any ulterior purpose whatever? It was incredible! Why, the whole portrait was evidently painted with no other object than that of indicating the rod's whereabouts. Either, then, there was or had been something else in the cavity in addition to the rod, or the rod was intended to be used in some way still unexplained. So much was beyond question. Thus cogitated Archibald--that is to say, thus he might have cogitated, for there is no direct evidence of what passed through his mind. And, in the first place, he made an exhaustive examination of the cavity, and convinced himself not only that there was nothing else except dust to be got out of it, but also that it opened into no other cavity which might prove more fruitful. His next step was to study the silver rod, in the hope that scrutiny or inspiration might suggest to him what it was good for. His pains were rewarded by finding on the flat head the nearly obliterated figures 3 and 5, inscribed one above the other, in the manner of a vulgar fraction, thus, 3/5; and by the conviction that the spiral conformation of the rod was not the result of accident, as he had at first supposed, but had been communicated to it intentionally, for some purpose unknown. These conclusions naturally stimulated his curiosity more than ever, but nothing came of it. The boy was a clever boy, but he was not a detective trained in this species of research, and the problem was beyond his ingenuity. He made every application of the figures 3 and 5 that imagination could suggest; he took them in feet, in inches, in yards; he added them together, and he subtracted one from the other: all in vain. The only thing he did not do was to take any one else into his confidence; he said not a word about the affair even to Kate; being resolved that if there were a mystery, it should be revealed, at least in the first instance, to no one else besides himself. At length, after several days spent in fruitless experiments and loss of temper, he returned the rod to its hiding-place, with the determination to give himself a rest for awhile, and see what time and accident would do for him. This plan, though undoubtedly prudent, seemed likely to effect no more than the others; and over a year passed away without the rod's being again disturbed. By
