"Well done!" Harry said as they pa.s.sed through the entrance.

"I told them not to close the path," Dias said. "We can do that now we are all together. Most of the rocks are too heavy for Jose and Maria to lift. Shall we build it up now, senor? I am sure they cannot force their way through while we four are holding the barricade."

"Certainly not, Dias, and I have no fear of their attempting it. But I think it would be as well for us to close it, otherwise we could not cross from one side to the other without exposing ourselves."

It took them two hours' hard work--the harder because the stones had to be thrown into the pa.s.sage from the sides, as the brigands might be crouching among the rocks higher up waiting for an opportunity to get a shot. At the end of the two hours the gap was filled up to the height of six feet.

"Now we can talk matters over quietly, Dias," Harry said. "We may take it that, whether they attack by day or by night, we can beat them off.

There is a little rill of water that trickles down along the centre, so we need not fear being driven out by thirst, and we have food enough to last us a fortnight. That is settled; but they may stay there for any time, and without exposing ourselves to sudden death we cannot find out whether they are still hanging about or not. Of course one very important question is, are they going to be joined by others?"

"I think they certainly will be, senor. As many of these fellows are hiding among the hills as would make a good-sized regiment, and they have only to send off two or three of their number with the news that a party of gold-diggers with five laden mules are shut up in this ravine to gather any number of them. They would come as quickly as vultures to a dead horse. It must be a long time since they had any really valuable plunder, and the fact that we have five baggage mules besides the three riding ones would show that we had probably been a very long time away, and might therefore possess a lot of gold."

"Are there any other pa.s.ses near?"

"The nearest, senor, is on the other branch of the Palcazu--the river we followed till we entered the pa.s.ses--and is about thirty miles to the north. The pa.s.s starts from a spot about fifteen miles above the junction, and goes up to Huaca, a place that is little more than ten miles south of Huanuco. From Huaca we could either follow the road to Cerro, or strike across the Western Cordilleras to Aguamiro."

"Then I think, Dias, that our best plan will be to go down again into the valley we left yesterday morning, and then strike across for the mouth of this pa.s.s you speak of. You know the direction?"

"I know the general direction, although I have never been along there."

"Well, Dias, you must be the guide. I should say the sooner we start the better. My idea is this: If you with your wife and Jose will start at once, so as to be down the pa.s.s before it gets dark, my brother and I will remain here. You will leave our riding mules at the point where the track is good enough for us to gallop on."

"We should not like to leave you, senor," Maria said.

"I have not the least fear of their attacking us, and with our rifles and double-barrelled guns and pistols we could beat them off if they did. I can't see any better way of getting out of this sc.r.a.pe, and am quite willing to adopt this plan."

"I don't see any other way, senor," Dias said. "The plan is a good one; but I wish I could stay here with you."

"But that would be impossible, Dias, for there would be no chance of our finding the mouth of this pa.s.s by ourselves."

"Why could we not all go together?" Maria asked.

"Because if there were no one here the brigands might discover that we had gone, within an hour or so of our starting. They might fire a shot or two, and, finding that we did not answer, crawl gradually down till they got here, for it must seem possible to them that we should return down the pa.s.s; and as there is no getting the baggage mules to go fast, we might very well be overtaken--I don't mean by those eight men, but by a considerable number."

"But how are you to find your way, senor?" Dias said.

"We shall follow the valley down till we come to the spot where you have struck off. You can fasten a white handkerchief to a stick and put it in some bare place where we are sure to see it. I want you to halt when you get to the river somewhere opposite the mouth of the pa.s.s. We will ride nearly due north, and when we strike the river will follow it down till we reach you."

"We can't halt opposite the mouth of the pa.s.s, for the river there is already some size, and we could not cross it. I shall keep along near the foot of the hills--the water there is shallow enough to ford. Then I will follow it down until, as you say, near the entrance to the pa.s.s, and there stop on the bank till you come."

"That will do very well. In that case it won't matter much where we strike the stream, as our mules can swim across easily enough--they have had plenty of practice during the past six months. However, we will turn off north where we can see your signal."

"When will you leave, senor?"

"To-morrow morning. I have no fear of their attacking during the night, for they can hardly bring other bands down here before morning. As soon as it gets dark we will light two torches and put them down at the foot of the barricade, so that we shall be in the shadow. These will show them that we are still here, and they won't care to venture down into the circle of light. We have let them know what a formidable amount of firearms we have, and have given them a lesson that we can shoot straight."

"They certainly would not come, senor, as long as your torches are burning, but three hours are as much as you can reckon upon their burning."

"Well, we have a dozen left now, Dias, and when they burn out we must light two more and throw them over and trust to their burning as they lie among the stones. Of course we should not think of going down to stick them upright, for the scoundrels will probably be watching us as closely as we are watching them. However, I shall manage to keep the lights going till daybreak, and shall start a good hour before that. We shall have to go down cautiously, and I should like to be well away with the mules before they discover that we have left. Now, the sooner you are off the better. Breakfast has been ready for the past hour. You had better eat it and get under weigh as soon as you can. After you have gone one of us will keep watch while the other eats. I have no doubt there will be plenty left for our supper."

"Yes, senor, and enough cakes to carry you on till you join us."

Half an hour later the party started, Dias having m.u.f.fled the mules'

hoofs, so that the clatter, as they pa.s.sed over the rocks, might not be heard above.

"Now, Bertie, you go down to breakfast. When you have done come up and relieve me. You have no occasion to hurry, for it is absolutely certain that they won't dare to attack till they get reinforcements."

When Bertie returned he said, "Here is a lot of food, Harry, they have hardly eaten anything. There is plenty for us to-day and to-morrow."

"That is just like them, Bertie; but I daresay they will camp in five or six hours. It feels quite lonely without them."

"That it does. It is really the first time we have been alone since we left Lima, except, of course, when we were out shooting together."

"Be sure you don't show your head above the barricade, Bertie. You must do as I have been doing, sit down here and look out through this peep-hole between these rocks Shove your rifle through it, so that, if you see a head looking out from between the rocks up there, you can fire at once."

In half an hour Harry came back and sat down by his brother, and, lighting their pipes, they chatted over the events of their journey and the prospect before them.

"I am afraid, Harry, the journey will be a failure, except that we have had a very jolly time."

"Well, so far it has not turned out much; but, somehow or other, I have great faith in this haunted castle. Of course the demons Dias is so afraid of are probably Indians, who are placed there to frighten intruders away, and they would not keep watch unless they had something to guard. I cannot understand how it has escaped the notice of the Spaniards all these years. I had not much faith in their stories until we found how true they were in all particulars as to what they call the golden river. There is one satisfaction, however: if the place is really a castle, it can hardly have disappeared under the lake. Of course if it is in ruins we may have a lot of difficulty in getting at the vaults, or wherever else treasure may have been buried; but unless it is a very big place, which is hardly probable, the work would be nothing compared with the draining of the lake."

"We have got nearly a year in hand, Harry, and can do a lot of work in that time, especially if we use powder."

"Yes; but, you see, we ought to allow at least five months for getting home. Still, no doubt if I felt justified in writing to ask for another three or four months, saying I had great hopes of finding something very good in a short time, she would stand out against her father a little longer. I shall write directly we get to Lima to say that, although I have so far failed, I do not give up hope, and am just starting on another enterprise that promises well." Bertie held up his finger. "I think I heard somebody move. It sounded like a stone being turned over." For two or three minutes he lay motionless, with his finger on the trigger. Then he fired.

"What was it, Bertie?"

"It was a man's leg. I suddenly saw it below that rift behind the rock.

I expect he had no idea that his foot showed there. I am pretty sure I hit it, for I had time to take a steady aim, and the foot disappeared the instant I fired. If he did not know it was exposed, there was no reason why he should have moved at all if he hadn't been hit."

"It was better to hit his foot than his head, Bertie. It is equally good as a lesson, if not better, for though we don't mean to let them kill us, I don't want to take life unless it is absolutely necessary.

Well, after that proof of the sharpness of our watch they are not likely to make any fresh move."

The day pa.s.sed slowly. They took it by turns to keep watch, and just before dusk Harry said, "I think, Bertie, that we might pull out the leaves and bush that Dias shoved into one of these gaps when he took the blankets and things out. I could push the torch through and fix it there, that would save having to cross the barricade. It is quite possible that one of those fellows may be keeping as sharp a look-out as we are doing, and it is as well not to set one's self up as a mark.

If I put it through now it won't show much, while if I wait till darkness falls it will be an easy object to fire at. You keep a sharp lookout while I am doing this, and if you see either a head or a gun try to hit it."

Harry accomplished the operation without drawing a shot, and as soon as he had fixed the torch he again stopped the hole up behind it.

"It is evident that they are not watching us very closely," he said.

"If they have not sent for help, they have gone off. With two of their men killed and two disabled, the fight must have been taken out of them. We will watch by turns to-night. It is six o'clock now; will you sit up till eleven, or shall I?"

"I don't care a bit. Which would you rather take?"

"I don't care;--however, I may as well take the first watch. We will start at five, so rouse me at four. If they come at all, which is possible, but not probable, it will be between four and five."

At ten o'clock Harry could see a glow of light at some distance from the mouth of the ravine, and in the stillness could occasionally catch the sound of voices. When he woke Bertie at twelve the lad looked at his watch and said, "You are an hour late in calling me, Harry."

"Yes, I had no inclination for sleep. The fellows have been reinforced.

Of course I don't know to what extent, but I should say pretty strongly. They have lit a big fire some distance from the ravine. They would not have dared to light one if they had not felt themselves strong enough to fight us. No doubt they have half a dozen men on watch where we first saw them, and these would give notice if we were coming.
