Their open-air life, and the toil of their recent travels had put both young men into the pink of condition; it was, therefore, not long before they reached the spot where Dick had made his momentous find. Arrived there, Earle’s first act was to subject each of the crystals lying in the exposed “pocket” to a careful examination. There were fifty-four in all, of varying sizes; and when Earle had pronounced each of them to be a genuine emerald—and most of them of the first water, they were all deposited in a knapsack which they had taken with them for the purpose. This done, the American seized a pickaxe and began to dig into the face of the cliff, pausing at intervals to take a rest while Cavendish shovelled away the débris. The rock was not at all difficult to work, yielding readily to the blows of the pickaxe and coming away in lumps the size of one’s fist, or even bigger, consequently it was not very long before, between them, they had excavated a cavity of considerable size. But after nearly two hours of strenuous toil without result, they retired from the hole for a time to rest, and were debating the question whether or not it was worth while to pursue the investigation any further, Earle being rather of opinion that Dick’s find had been merely an isolated pocket, and that they might seek for weeks or possibly months, without finding any more emeralds, when, without the slightest warning, the hole in which they had been working suddenly caved in, laying bare a new face, some nine or ten square yards in area. And when at length the face had ceased to crumble and the dust had subsided, the first thing to attract their attention was an emerald nearly as big as a duck’s egg projecting from the newly exposed rock. This they carefully dug out, afterwards proceeding to search among the fallen rock, in which they eventually found two other very fine stones.

“There!” exclaimed Earle, with a sigh of satisfaction, when at length they had thoroughly examined and cleared away the fallen rock. “I guess we’ve done enough; for we’ve demonstrated that this is a sure-’nough mine. See that stuff round the place where we picked out the emerald? That is calcite, and this rock is a black limestone; all the indications are, therefore, in favour of this being a genuine emerald mine, which we can work, if we choose, on our return journey. Now, we’ll just dig out that mass of calcite and carefully cover it up, so that in the exceedingly unlikely event of any other prospector passing this way, there will be little or nothing to attract his attention; and to-morrow, before we resume our march, we will determine the exact position of this spot by astronomical observations and make a note of it in our diaries, so that we can find the place again. Meanwhile, we have not done at all badly this afternoon, for I guess the contents of this knapsack are worth a good many thousand dollars.”

It was nightfall by the time that the explorers got back to their camp, and they were bone-weary from their extraordinary exertions; but they had, as recompense, the knowledge that they had left their mine in such a condition that no mere casual visitor would be in the least likely to suspect its existence.

Immediately after breakfast on the following morning the party struck camp and proceeded to climb the cleft. It cost the Indian carriers half an hour’s severe toil to accomplish the ascent, and when at length they reached the summit they were only too glad to lay down their burdens and take a rest while the two leaders, with the assistance of their pocket sextants and Earle’s pocket chronometer, determined the position of the head of the gully. This done, and the calculations worked out and checked, the march was resumed; the outer edge of the forest through which their route lay being reached shortly after noon. And when at length they sat down to their mid-day meal, all hands enjoyed an unusual luxury; for about an hour before pitching camp, Dick, who chanced to be leading the way, saw and shot something as it attempted to make off through the long grass, that something proving to be a strange creature partaking, in about equal proportions, of the characteristics of a pig and a deer. Dick, of course, not being a naturalist, was unable to name the creature, and even Earle declared himself puzzled; but whatever it may have been, its flesh proved to be exceptionally tender, juicy, and delicious, and the Indians fairly gorged themselves with it.

The forest into which the party plunged when the march was resumed proved to be entirely different in character from that which they had previously traversed. To begin with, the trees were all of new and strange species, mostly bearing foliage of dark and gloomy tints; they stood much farther apart; the undergrowth was sparse, or absent altogether; and there were no orchids, or long, trailing garlands of lovely parasitic growth which had rendered the forests already traversed so strangely beautiful. Another peculiarity of the forest was that scarcely a bird was to be seen, excepting an occasional vulture or carrion crow perched upon some lightning-blasted stump. Moreover, there was a strange silence pervading the place, a silence that seemed almost uncanny, as though insects as well as birds shunned the place. Altogether, the effect of the silence, the sombre tints of the foliage, the absence of brilliant-hued blooms, and a certain subtle something in the atmosphere, was distinctly depressing. There was one redeeming feature about it, however, which was that the sparseness of the underbush and the greater space between the trunks of the trees rendered travelling comparatively easy, and the party made good progress.

As they plunged farther into the depths of the forest, however, they began to realise that its gloomy aisles were by no means so devoid of life as they had at first imagined. The first intimation of this fact came to them in the form of a sudden yell from one of the Indian carriers, who declared that he had been bitten on the leg by something; and upon investigation this proved to be the case, for the calf of his bare leg showed two tiny punctures, not more than one-eighth of an inch apart, the flesh around which, even as Earle and Dick examined the wounds, began to swell and turn a curious blue tint, while the injured man rapidly lost the power of speech and voluntary movements, though his body began to be shaken by violent tremors.

Earle now showed himself to be a man of prompt action. Whipping his keen hunting knife out of its sheath, he slashed open the flesh athwart the two punctures and then, kneeling down, applied his lips to the wound and sucked it strongly until the blood began to come, at first sluggishly and in coagulated clots, but eventually more freely. It was noticeable, too, that at first the blood was almost black in colour, but by dint of vigorous sucking it at length came freely and changed to its normal colour. Meanwhile, Dick, recalling conversations which he had had with Earle, in which the latter had described certain rough and ready methods which he had successfully adopted in treating venomous snake bites, opened a shot cartridge, extracted the powder therefrom, and with it made a squib. This he had ready long before Earle was prepared to use it; but when at length the blood was flowing freely and naturally from the wound, they laid the now comatose victim prone upon the ground, and, while Dick held the wounded limb in position, Earl applied the squib to the wound and fired it. The result was that the wound was quickly and very effectively cauterised, apparently without inflicting the slightest suffering upon the victim, who never moved a muscle while the squib spluttered and burned upon his raw flesh. Earle then quickly and deftly dressed the wound and bound it up, after which he proceeded to revive his patient by moistening his lips with raw whiskey, with which he finally drenched the man internally as soon as the unfortunate fellow was able to swallow.

But, of course, there was no more marching for the party that day, and preparations were at once made for pitching the camp. The first task was to beat the long, dry grass thoroughly, in order to drive away the snake which had bitten the man, or any other snakes which might be lurking therein. But this procedure, while it may possibly have had the desired effect, had also another, by no means desirable; for it was soon discovered that the threshing had aroused the anger of a legion of enormous black ants—fierce, venomous creatures nearly an inch long—which came swarming by thousands up out of holes in the ground, and attacked the intruders with indescribable ferocity. The unfortunate semi-naked Indians instantly scattered in ignominious flight, leaving the two white men to deal with the situation as best they could. And although Earle and Dick were, of course, fully clothed, and their bodies were therefore reasonably well protected, they were both severely bitten before, by setting fire to the grass and allowing it to blaze for a few seconds before beating it out, they were able to put the foe to flight. The burning of the grass, however, revealed the fact that the soil was everywhere honeycombed with holes, into which the creatures had doubtless retreated, ready to sally forth again upon the smallest provocation; therefore, in order to protect themselves from further attack, they cut an immense quantity of grass, strewed it over the central portion of the already burnt area, and burned it over again; after which, the ashes being first swept away with branches, they ventured to go into camp, the Indians slinking back by twos and threes as soon as they perceived that the risk of renewed hostilities was over. As for the two white men, although they bathed their hurts with dilute ammonia as quickly as they could, they both suffered acutely, to such an extent, indeed, that they were both in a high state of fever, bordering on delirium, before midnight. Earle, however, foreseeing what was impending, mixed for himself and Dick a strong draught, which no doubt helped to avert even worse consequences, and by dawn of the following morning the fever was conquered and the sufferers sank into a somewhat troubled sleep, from which the faithful Peter would not permit them to be aroused upon any pretext whatsoever. As for the bitten man, he suffered severely for several hours, the wounded limb swelling to about three times its normal size, while acute pains shot through the whole of his tortured body; but at length these gradually grew less, until he sank into a state of coma which eventually became natural sleep, during which the swollen limb gradually resumed its normal dimensions. When he at length awoke, beyond being troubled with a dazed feeling and, of course, a considerable amount of pain arising from the cauterisation of the wound, he seemed to be little the worse for his adventure; and when at length the party struck camp and resumed their march shortly after mid-day, he was able to hobble along with the rest, although it was found necessary to relieve him of all work during that day.

Such was the first adventure of the party in that terrible forest; but there were others still worse to follow, as they soon found. Nothing very particular, however, befell them on that second day’s march, for after their experiences of the previous day they were careful to conduct their march with all due precaution, Inaguy leading the way and industriously beating the grass before him with a long, slender switch, while Dick and Earle, following him on either flank, did likewise. And the wisdom of this method of procedure was manifested a dozen times or more during the afternoon’s march by sudden, quick scurrying sounds in the grass immediately ahead, bearing witness to the fact that a lurking snake had been startled and was effecting a hasty retreat.

When at length the time came to pitch camp for the night, the tactics of the previous day were repeated, the grass being thoroughly burnt away over an area spacious enough to accommodate the party. And here again the wisdom of their action was made manifest; for when the ashes were swept up for removal the shrivelled remains of several centipedes and scorpions—some of them of quite unusual size—were found, which would doubtless have given trouble had not the flames rendered them harmless.
