Then Earle was again invited to subject himself to the same ordeal, and this time he did so without demur, stripping off first his thin linen jacket, and next the light woollen singlet which he was wearing as a substitute for a shirt.

And now came a startling surprise. For the removal of Earle’s singlet revealed the curious lozenge-shaped jewel with its inset emerald, which he had removed from the neck of the idol in the sculptured cave discovered by Dick, and which the American had ever since worn round his neck for safe keeping. No sooner did the eyes of the examining officer glimpse the jewel than he uttered a strange cry, suggestive of the utmost astonishment. He gazed upon it with awe-struck eyes, drew cautiously near to inspect it more closely, half stretched forth a hand, seemingly to touch it, and then, suddenly, saying something to Adoni which seemed to suggest that a most wonderful and amazing thing had happened, prostrated himself at Earle’s feet, an example which Adoni instantly followed.

“Now, what in the nation does this mean?” demanded Earle in a low voice of Dick. “Why are these two guys kowtowing to me in this fashion? Gee! They surely don’t think that I’m some fancy god of theirs, come down from Olympus to visit them, as a special mark of favour, do they?”

“Well, it looks very much like it, by the way that they are carrying on,” returned Dick. “I think that it might help matters a bit, both now and in the future, if you were to play up to the idea and infuse a general air of benevolent condescension into your intercourse with them. I don’t see that it could possibly do any harm. Do you?”

“Don’t know,” answered Earle. “It might if, later on, they were to come to me and demand that I do some impossible thing for them. But, on the other hand, I guess it would be up to me to refuse, if I chose. On the whole, perhaps—and yet, I don’t know—Yes, I guess I’ll try it, and see how it works.”

Bending down, he lightly touched the two officers upon the shoulder and, when they ventured to glance up at him, graciously signed to them to rise, which they did, with every mark of the most profound reverence. From that moment there was no further trouble. Without waiting for permission from the examining officer, Earle calmly resumed his singlet and coat, taking care now, however, to leave fully exposed the jewel, or amulet, or whatever it was, that had produced such a wonderful effect; and this done, he signed to Adoni to open the gate and admit Inaguy and the rest of the Indians, which was instantly done. In the meantime, while the Indians were with much deliberation gathering up their loads and adjusting them upon their shoulders, in response to Earle’s reassuring call, Adoni and the other officer had withdrawn to a little distance and were plunged into an earnest, anxious consultation, the result of which was that, a few minutes later, a man, naked save for a sort of breech cloth wrapped about his loins, started out from the guard house and set off down the road leading to the city, as though running for his life.

As the last of the Indians passed through the gateway, the massive timber gates were closed and securely barred behind them, and Earle and Dick stepped forward to place themselves at their head, intending to resume their march toward Ulua. But Adoni, perceiving their intention, at once intervened and, firmly yet with the utmost reverence of manner, intimated by signs an earnest desire that the party would postpone their departure. He did this by standing before them in the middle of the road, with his arms outstretched as though to bar the way; then he signed to the Indians to remove themselves to a wide plot of grass by the side of the road and deposit their burden there; and finally beckoned the two white men to accompany him into the guard house, where he conducted them into a plainly but comfortably furnished room, and signed to them a request to rest themselves upon a couple of couches which he indicated, at the same time giving them to understand that a meal would presently be served to them.

Earle, well pleased at the success which had attended his effort to penetrate to the interior of the forbidden country, signified his acquiescence by seating himself on one of the couches, whereupon Adoni, equally well pleased, withdrew, with a profound bow, leaving the two friends to themselves.

“Well,” remarked Earle, rising from the couch and gazing with satisfaction upon the glorious prospect of lake and valley revealed by the window opening before which he placed himself, “we are inside the gate, and that is something achieved, anyway. For, at first, I feared that they were going to refuse us admission, and if they had done so I guess we should have found it a pretty difficult matter to get in. But our friend Adoni has evidently no authority to allow us to go on without first referring to the boss, whoever he may be; and I guess that naked runner was the bearer of a report and a request for further instructions. Now of course our line of conduct will be to conform to the manners and customs of the natives, so far as may be, and give no trouble; for our only object in coming here is to see the country and the people, and that can best be accomplished by keeping on good terms with everybody; therefore we will just let them make all the arrangements, and we will fall in with them. But I have great hopes from the possession of this jewel, which evidently has some powerful mystic significance in the eyes of these people. Adoni and the other fellow appeared to recognise it at once, and there can be no question as to the reverence with which they regard it. Judging from the behaviour of those two, the thing ought to secure us a very favourable reception at headquarters. I wish I knew the history of it.”

“We shall perhaps learn that later on,” returned Dick. “And I anticipate that when we do, it will prove both curious and romantic. The mere finding of it in that wonderful cavern was remarkable enough, but the astonishment and delight of Adoni at recognising it were still more remarkable, to my mind. To me, their behaviour was that of men suddenly brought face to face with something that they had almost despaired of ever seeing again.”
