Chapter Twenty Seven.

The Key at Last.

“Well, Fanning, I guess this time it’s all U.P.”

Renshaw made no reply. He gazed wearily at the great iron-bound hills, whose cliffs were now beginning to reflect the glow of the declining sun—and chipped mechanically at the rocks with the geological hammer in his hand. His mind upon the subject was much the same as that of his companion; but in actual fact his despondency was far greater. Still with the desperate tenacity born of the habits of a lifetime, he was unwilling to give in.

Four days have gone by since we last saw our two adventurers bivouacking under the cliff—four days of threading mazy defiles and climbing the roof-like sides of mountains—four days of burning, sweltering exhaustion, ever eager, ever energetic with the tenfold vigour of a fierce hunt for riches. Three out of the four have been devoted to nothing but prospecting for their quest, for they passed the third beacon—the third turret-headed mountain of the clue—early on the day following that on which we last saw them—and now, worn out with toil and disappointment! they are resting in the sweltering afternoon heat deep down in a rock-bound valley where not a breath of air can come—not a whisper of a stir to relieve the oven-like glow which is rendering Sellon, at any rate, almost light-headed.

“A blank draw this time,” growled the latter, wearily. “And what an awful business it has been to get here! I wouldn’t go through it again for a thousand pounds. And then, just think what a brace of fools we shall look to the people at Sunningdale.”

Then as if the thought of Sunningdale—and what he had left there—put the crowning stone upon his misery, Sellon proceeded to curse most vehemently.

With weariness and disappointment, misfortune had overtaken our two friends since we saw them last. While riding along the burning sandy bottom of a dreary defile towards evening, the led horse had inadvertently trodden on a puff-adder—which, sluggish brute that it is, rarely gets out of the way. Blowing himself out with rage, this hideous reptile had flung up his squat bloated length, fastening his fangs in the leg of the unfortunate horse. The animal was doomed, and, indeed, in less than an hour was in its expiring throes.

Now, this was a terrible misfortune, for not only was the climbing and digging gear among the pack-load, but also the water-skin, and by far the greater part of their provisions; nearly the whole of the latter had to be abandoned, and loading up all that was indispensable upon their riding horses—already fast losing their former freshness—the two adventurers had pushed on. But by now the contents of the water-skin had run very low indeed; were it not for the lucky find of a tiny pool of slimy fetid water standing in a cavity of a rock, the horses would have given out already. As it was, they drank it up every drop, and felt the better for it.

“I doubt whether that bag of bones will carry me back, as it is,” said Sellon, gloomily, eyeing his dejected steed, now too weary to graze.

“Sellon,” said Renshaw, earnestly, still gazing around and completely ignoring his companion’s last remark—“Sellon, I can’t make it out now any more than the first time I was here. We have followed out the clue most minutely: ‘Straight from the smaller turret-head, facing the setting sun. Within a day’s ride.’ Now, we have explored and surveyed every point westerly between north and south, and within a good deal more than a day’s ride, thoroughly and exhaustively. There isn’t the shadow of a trace of any such valley, or rather crater, as old Greenway describes. But let’s go over the thing carefully again.”

Suddenly Maurice sat up from his weary lounging attitude.

“By Jove, Fanning, but you’ve given me an idea,” he said, speaking eagerly and quickly.

“One moment,” said Renshaw, holding up his hand. “I have an idea, too, and indeed it’s astonishing it should never have struck me before. You must remember old Greenway was talking very disjointedly at the end of his yarn—poor old chap. He was nearly played out. Well, I tried to take down his words exactly as he uttered them. Look at this ‘Straight from—the smaller one—facing the setting sun. Within—day’s ride.’ Does nothing strike you now?”

“Can’t say it does,” growled Sellon, “except that the old sinner must have been telling a most infernal lie. We’ve spent the last four days fossicking around within a day’s ride of his turret-top mountain, and devil a valley of the kind he describes exists.”

“Well, what strikes me is this. He may have meant to say ‘Within two days’, or three days’, or four days’ ride.’ See?”

“Yes. If that’s so he might as well have told us there was plenty of gold to be found between this and Morocco. It would have helped us about as much. But now I’ll give you my idea. It sounds ‘tall,’ and I dare say you’ll laugh.”

“Never mind. Drive on,” rejoined Renshaw, looking up from the paper which he had been studying intently.

“Well, you mentioned the word ‘crater’ just now. If this ‘valley’ of old Stick-in-the-mud’s really exists, it is, as you say, a crater-shaped concern. Now we’ve fooled away days in hunting for this place at the bottom of each and every mountain around. What if, after all, we ought to be looking for it at the top?”

An eager flash leaped from the other’s eyes.

“By Jove! That is an idea!” he burst forth.

“Eh! Not a bad one, I think?” said Sellon, complacently.

“No. It just isn’t.”

For a few moments both sat staring at each other. Sellon was the first to speak.

“How about that queer cock’s-comb-looking peak we came round this morning?” he said. But Renshaw shook his head.

“Not that. There’s no room for any such place on top of it.”

“Not, eh? Look here, Fanning. Have you ever been up it?”

“No. But I’ve been to the top of every blessed berg of any considerable height around. I never went up that because it commands no range of ground that the others don’t.”

“Very well. My theory is that the best thing we can do is to make the ascent forthwith. Let me look at the yarn for a moment. Ah, here it is,” he went on, pointing out a place on the soiled and weather-beaten document. “‘We were looking about for a hole in a cave to sleep in, for it was coldish up there of nights.’ ‘Up there’ you notice. Now, from its conformation, that cock’s-comb is about the only mountain top around here where they would be likely to find ‘a hole or a cave,’ for ‘up there’ points to the top of the mountain or near it. Do you follow?”

Renshaw nodded.

“All right. ‘I saw we were skirting a deep valley—though it was more like a hole than a valley, for there was no way in or out,’” quoted Sellon again. “Now, you would hardly find such a formation at the bottom of a mountain—though you very conceivably might at the top.”

“But I tell you there can’t be room for such a thing at the top of that cock’s-comb,” objected Renshaw, dubiously. “I’ve been all round the mountain more than once, and it’s narrow at the top.”

“Maybe. On the other hand, it may not be so narrow as you think. A mountain is the devil for changing its shape from whatever point you look at it—almost in whatever light or shade. Then, again, Greenway may have exaggerated the size of the hole. I tell you what it is, Fanning old chap. I believe I’ve solved the riddle that has been besting you all these years. As you said when we first talked the affair over, ‘two heads are better than one—even donkeys’ heads,’ There’s a third head, and that’s the head of the ‘right nail,’ and I believe we’ve hit it. Saddle up.”

“Don’t be too sanguine, Sellon. You’ll be doubly sold if your idea ends in smoke.”

They were not long in reaching the mountain referred to. It was of conical formation and flat-topped. But from one end of its table-like summit rose a precipitous, razor-backed ridge—serrated and on its broader side taking the shape of a cock’s-comb.

Though steep and in parts rugged, the ascent was easy; indeed, it seemed likely they could ride to the very summit. Renshaw eyeing the towering slope, shook his head.

“It’s rough on the horses,” he said. “They haven’t got any superfluous energy at this stage of the proceedings, and that berg can’t stand much under three thousand feet. Still they’ve got to go with us. If we left them down here they might be jumped; and then, again, if your idea should be the right one, we might be days up there. I only hope we shall find water, anyhow.”
