I noticed it, though you did not. I have little doubt that Monella noticed it too. The cavern was formerly all open, or, at least, it had a large opening, and I am almost certain its floor was originally level with the ground outside. If so, the present floor is artificial, and there are probably vaults beneath. Outside, the stonework is so artfully done that you see no trace of it; it appears to be all solid rock; but inside I saw distinctly traces of the joints. Then, look at these archways, at the one we are now sitting under! They have been worked upon too – to enlarge them, probably; to give more head-room when the floor was made higher. See! here are marks of the chisel!” And Templemore got up and pointed to many places where the marks left by the tool were clearly to be seen.

      “Well,” said Elwood, “I suppose we shall solve the problem and set all doubts at rest before many days are over. For my part I am in a curious state of mind about it – half impatient, half the reverse. If it is to turn out as you say, I am in no hurry to terminate the uncertainty. This strange spot, the fact that we are really, at last, inside the wonderful mountain – these things open such a vista of marvellous possibilities that I – it seems to me – I would rather, you know – ”

      “Oh, yes, I know, you old dreamer,” Jack exclaimed, laughing. “You would rather wait and have time to dream on for a while than have your dreams rudely dispelled by hard facts. Now suppose we go and take a look round in the shade over there. We need not go out of sight of this entrance; so that Monella will find us immediately he returns.”

      The sun had now moved so far over that one side of the valley was lying in shadow, and they strolled out to observe more closely the new flowers and plants they had thus far seen only from a distance.

      CHAPTER VIII

      ALONE ON RORAIMA’S SUMMIT

      When Monella returned about two hours later, the two young men had much to tell him of the wonderful flowers and plants they had found, of strange fish in the water, and curious perfumed butterflies that they had mistaken for flowers.

      There were many of these extraordinary insects flying about. In colouring and shape they resembled some of the flowers; when resting upon a spray or twig they looked exactly like blossoms, and upon nearing them, one became conscious of a most exquisite scent. But just when one leaned a little nearer to smell the supposed flower, it would flutter quickly away, and insect and perfume disappeared altogether. Many of the flowers that were scattered about the rocks were shaped like exquisitely moulded wax bells of all sorts and kinds of colours and patterns, white, red, yellow, blue, etc., striped, spotted, speckled. So distinct were they from anything the explorers had before seen, that they had picked some and brought them into the cavern to show Monella; but he could not give them a name.

      The stream from the waterfall, they found, disappeared into the ground just before it reached the cavern. No doubt this was the stream they had seen issuing from the rock upon the other side.

      At the further end the valley began to rise, following the stream, which came down in a series of small falls or cataracts. About this part they had found some other caves; but had not entered them.

      “And most remarkable of all,” said Templemore, “we have not seen a single snake, lizard, or reptile of any sort or kind. Yet this is just the sort of place one would have expected to be full of them. Nor have we seen either animals or birds.”

      Monella told them the Indians still refused to enter the cave. They all three, therefore, went to the ‘window,’ and assisted to get their camp equipage inside, the Indians bringing the things to the top of the ladder and handing them through the opening. They preferred, themselves, to camp outside, and had already made a fire to cook some monkeys they had killed with bows and arrows.

      When all their things were safe inside, Leonard and Jack took some fishing nets and soon caught some fish in the pools of the stream in the canyon. They then made a fire just outside the cavern entrance, and cooked them for their evening meal. The fish seemed to be a kind of trout, but of a species they had never seen before.

      Monella expressed his regret that all attempts to persuade the Indians out of their fear of ‘the demon-haunted mountain’ had failed.

      “They will neither come inside nor remain outside by themselves; that is, if we go away from here to explore farther. It seems to me, therefore, that we ought to have all our stores brought here before we start, and then let the Indians go back by themselves. We may be here for months, so had better get them to fetch everything we can possibly require from ‘Monella Lodge.’”

      Such was Monella’s advice.

      “It will take two or three days at least – possibly more,” he continued, “to transport all our stores here. During that time we must be content to attend to nothing else, and postpone any further exploration of the mountain. Besides, when we once start, none can tell how far we may be led on. Better have our ‘base of operations’ settled and secure first. How far away are those other caves that you saw?”

      “About a quarter of a mile,” Jack answered.

      “We will have a look at them in the morning,” Monella said thoughtfully. “It may be wiser to hide some of our stores and belongings in different places, so that, if any accident should happen to one lot, the others may be all right. Eh, Templemore?”

      “Just the very idea I had in my head when I spoke to you of those other caves,” Jack responded. “We can take half an hour or so to explore them in the morning.”

      “Better take longer,” observed Monella. “Better take the day, and do it thoroughly. Much may depend upon it hereafter. Suppose, therefore, that you remain here while Elwood and I return to ‘Monella Lodge’ and see about packing and bringing some of the ‘belongings’? Then, if we find another journey necessary, you can go next time, and Elwood and I will remain here on guard. But we cannot get back to-morrow night. Do you mind staying here alone?”

      “Not I!” said Jack, laughing.

      “Very well then; we will arrange it so. We shall load up our two animals, and perhaps one journey will suffice after all. Any way, you hunt for the best and most secret hiding-places you can find. See that they are dry, you know. There are the three casks of powder – ”

      “What! Will you bring them too?”

      “Certainly. We may have blasting to do before we have done with what we have in hand. The extra arms, too, we will divide, and secrete in different places.”

      “I see the idea,” Jack assented. “Rely on me to do the best that can be done.”

      The three went back, after their meal, to where the Indians were camping just outside the ‘window.’ Matava looked grave, and shook his head dubiously, when Leonard told him of the arrangements come to.

      “My heart is heavy, my master,” he said in his own language, “at the thought of leaving you to fight the demons of the mountain. It is not good this thing that you are about to undertake. Doubtless the demons have left this place open as a trap to tempt you to enter their country. When you are well inside they will close it and have you securely captured and we shall never see you more. Alas! that my mother should ever have said aught to lead you on to this terrible enterprise. Better had she died first. I feel sure, if you go inside there, we shall never see you again!”

      Elwood only smiled, and bid him be of good cheer.

      “We shall return,” he replied, “and, I trust, not empty-handed. And, if so, you and my old nurse shall share in my good fortune. But, if you think there is danger, why do you not come with us to help? It is not like a brave Indian to be afraid!”

      The Indian shook his head and sighed.

      “Matava is no coward,” he responded. “His master knows that well. Against all earthly dangers Matava will help him to his last breath, but to battle with the demons of Roraima is but madness – and it is useless. No mortal man may brave them and live. Some one must take the tale to those left behind. It is not good that they should never know.”

      “That is a nice way of getting out of it, Matava,” said Templemore, who had just come
