"Tick, you mean?"

"Yes, tick. Now, it struck me that this would do for the crackers. We should have to cut it in strips three or four times the width of the cracker. Then we could get Maria to make us some stiff paste; starch would be better, but of course we have none. Then, taking a strip of the cloth, we would turn over one side of it an inch from the edge to make a sort of trough, pour in the gunpowder, carefully paste all the rest of it and fold it over and over, and then, when it begins to dry, double it up and tie it with string. We should then only have to add touch-paper, which, of course, we could make out of anything, and put into the end fold. We could break up a few of the cartridges, soak them in wetted powder, and then cut them up into small pieces and stick them into the ends of the crackers. I think that would do first-rate. I have made dozens of crackers, and feel sure that I could turn out a good lot of them now. The squibs will be easier; we should only have to paste one side of the strips and roll them up so as to form suitable cases.

When these are dry we should put a thimbleful of powder into each, and then fill them up with powder and charcoal. In order to make sure of a loud bang we could undo a piece of rope and wind the strands round each case for an inch and a half from the bottom. Of course, when we had ground down the burned wood we would mix it with powder and try one or two of the squibs, so as to find the proportions of charcoal to be used."

"You have evidently thought it all out well, and I think it does you no end of credit. I authorize you to begin the experiment at once. The first thing, of course, will be to get some wood and char it. I should think that you would require at least two pounds of that to two pounds of powder; but you had better only do a little at first--just enough to make an experiment. You know it will require ramming down well."

When Dias, who was on watch, returned he found Bertie at work burning pieces of wood and sc.r.a.ping off the charred surface. Harry explained the plan to him. As he had frequently seen fireworks at Lima, Dias quickly grasped the idea.

"It is splendid, senor; those things will frighten them far more than guns. They will think so many devils have got among them, and we will heighten the effect by discharging every piece that we can among them.

In their confusion they will think it is the fireworks that are killing them. That would be necessary, for otherwise when they recovered from the panic and found that no one had been hurt, they might summon up courage to return."

At noon the next day Bertie with a.s.sistance had four squibs and two crackers ready for trial. The squibs contained respectively one, two, three, and four parts of charcoal to one of powder.

"Don't hold them in your hand while you are trying the experiment, Bertie. Lay them down on that stone one by one and touch them off with a burning brand from the fire, and take care that you have a good long one."

All, with the exception of Jose who was on watch, gathered round. The first squib exploded with a bang, the second did the same, but with less violence, the third went off in an explosive spurt, the fourth burned as a squib should do, though a little fiercely, and gave a good bang at the end.

"They go off rather too rapidly, Bertie," Harry said; "we should want them to whiz about in a lively way as long as possible. I should put in five parts of that burned wood next time."

"I will try at once," Bertie said. "I have got lots of cases made, and enough burned stuff to make eight or ten more."

The mixture was soon made and another case charged, Bertie ramming down the mixture with a stick which he had cut to fit exactly, and a heavy stone as a hammer. This was done after each half-spoonful of the mixture was poured in. Then he inserted a strip of his touch-paper.

"I will take this in my hand," he said, "there is no fear of its exploding. I want to throw it into the air and see how it burns there."

The touch-paper was lit, and when the mixture started burning Bertie waved the squib high above his head and threw it into the air. It flew along some fifteen yards and then exploded.

"I don't think you can better that, Bertie. But you might make the cases a bit stronger; it burned out a little too quickly. We shall probably not be able to get very close to them."

The cracker was equally satisfactory, except that they agreed that a somewhat larger charge of powder should be used to increase the noise of the explosion.

"Now, Bertie," Harry said, "we will put all hands on to the business.

Donna Maria shall make a good stock of paste, and cut the tick into strips for both widths. You shall make the cases for the squibs. Dias and I will take charge of the manufacture of charcoal. That will be a long job, for as you have two pounds of gunpowder we shall want ten of this charred wood."

"Not quite as much as that, Harry, because we shall want the powder alone for the crackers and the bangs of the squibs, and also for making the touch-paper for all of them."

"Well, we will say ten pounds, anyhow. We have a big stock of cartridges, and can spare a few of them for so good a purpose."

They were soon at work. By night the cases were all made and drying, and were left near the fire so as to be ready for filling in the morning.

Dias then said: "Jose will go down to-night, senor. Of course I shall go with him. We must find out, in the first place, how near the mouth of the ravine the savages are gathered, whether they keep any watch, and what force they have. It will be well not to make ourselves known to them until at least the greater part are gathered there. If we were only to scare a small party, the others, when they came down, would know nothing of the panic, and might take up the pursuit."

"I wish we had some means of driving them off the top of the hill, Dias."

"I don't see how that can be done, senor. But probably in another day or two they will all go down of their own accord. They must by this time have satisfied themselves that there is no getting at us from above, and that it would be too dangerous to attempt a descent here under the fire of our guns. They will be very likely, instead, to go down to-morrow or next day to hold a general council, and in that case they may decide either to risk climbing down at night, or to make a grand a.s.sault on the breast-work. Or, if they cannot bring themselves to that, they may decide to leave half a dozen men to watch the entrance, while the rest scatter themselves over the forests. In that case the watchers would only have to go off and summon them when we started again. As they might well imagine that we should not find another position like this again, I expect that is what they will do.

If there are a hundred of them, they will find it difficult to feed themselves long. Certainly the men on the hills will get little to eat up there."

"Well, Dias, be sure you warn Jose to be careful. They may be posting sentries at the mouth of the ravine, just as they are keeping them at this end."

"They may be, but I do not think it is likely; they will know that we could not abandon our animals, and that if we pa.s.sed through they would have no difficulty in over-taking us, and would then have us at their mercy. The last thing they would want is to prevent us from leaving this position. They certainly would not fear an attack from us, knowing that there are but four of us and a woman. Therefore, I think it probable that they will keep at some little distance from the entrance, so as to tempt us to come out."

"I hope it is so, Dias. Still, Jose will have to be very careful."

"He will be careful, senor. He knows his own life will depend upon his crawling along as noiselessly as a snake. If he is seen, of course he will come at all speed back to me; and, unless he is. .h.i.t by a chance arrow, he will not run much risk, for by the time they are ready to shoot he will be out of sight on such dark nights as these, and in the shade of the mountains and trees. I shall be ready to send four barrels of buck-shot among them when they come up. That is sure to stop them long enough to allow us to get under the cover of your rifles before they can overtake us.

"I don't think that you need be at all uneasy about him, senor. We will start in an hour's time, so that Jose can get near them before they go to sleep. They will probably have a fire burning, but if not the only guide to their position will be the sound of their talking. He will strip before he leaves me, so that if they catch sight of him, they will suppose that he is one of themselves."

Bertie now relieved Jose, who came back and had a long talk with Dias.

"We are ready now, senor."

"Here is my fowling-piece. It is already loaded with buck-shot. Bertie has taken down his rifle and gun, and will give you the latter as you pa.s.s. I suppose Jose will take no weapons?"

"Only a long knife, senor, that may be useful if he comes upon one of them suddenly."

At the barricade Jose stripped, retaining only a pair of sandals. These were as noiseless as his bare feet, and would be needed, as in the dark he might tread upon a th.o.r.n.y creeper, or strike against a projecting rock.

"Good-bye, Jose!" Harry said. "Now, be careful. It would be a great grief to us if anything happened to you."

"I will be careful, senor. The Indians won't catch me, never fear."

Harry and Bertie both shook hands with him, and then he and Dias stepped into the water, and, keeping close along by the wall of rock, started on their perilous expedition.

"I don't like it, Bert," Harry said as they lost sight of them. "It seems a cowardly thing to let that lad go into danger while we are doing nothing."

"That is just what I feel, Harry. I would have volunteered willingly, but he will do it a great deal better than either you or I could."

"There is no doubt about that," Harry agreed. "Of course when he is out with the mules he often travels at night, and certainly both he and Dias can see in the dark a good deal better than we can."

There was suddenly a slight movement behind them, and they turned sharply round. "It is I, senor. I am anxious about Dias, and I didn't like staying there by myself. I thought you would not mind if I came up and sat by you."

"Certainly not," Harry said. "Sit down and make yourself comfortable. I do not think there is any fear for Dias. He cannot be taken by surprise, for he will hear by their shouting if they discover Jose, and you may be quite sure that he will bring them to a stand with the four shots he will fire among them as they come near, and so will get a good start. They might run faster than he can in the forest, but will scarcely be better able to make their way up the torrent."

When Dias had been gone twenty minutes their conversation ceased, and they sat listening intently. In another ten minutes, which seemed an hour to them, Harry said, "The savages can keep no watch at their end of the torrent, and Jose must have got safely away."

Very slowly the time pa.s.sed.

"They must have been gone an hour," Bertie said at last.

"Quite that, I should think, Bertie. At any rate, we may feel a.s.sured that all has gone well so far. For, though we might not hear the yells of the savages over the rustle and roar of the torrent, we should certainly hear gunshots."

Another half-hour pa.s.sed, and then to their relief they heard Dias call out, "All is well!" some little distance down. In three or four minutes they could see the two figures approaching. "Give me your guns, Dias,"

Harry said, "and then I will help you up the rocks. They might go off if you were to make a slip. Now, while Jose is putting on his clothes, tell me what he has found out."

"I have not heard much, senor. As soon as he rejoined me we started off, and, coming up the torrent, we had not much chance of talking. He told me that there were many of them, and that they were camped at some little distance from the stream, just as I thought they would be."

"I will stay here, Harry," Bertie said. "You can hear the news and then come and tell me."

"Very well. I will be back before long."
