Stanley then descended the steps, and rejoined Harry below. Before going down further, Stanley, who had during the day informed Harry of his plan, told him of the start that they had made.

"Of course, it all depends upon what stones you meet with," Harry said. "If you come to a big solid block, I don't see how you are going to get through it."

"We have the hatchets, and can whittle it away; and perhaps we can make some chisels, from the ramrods of your guards' guns. A lot can be done, with patience and plenty of hands."

Stanley then went down below, and explained to the others the plan proposed. The news gave them great satisfaction; for although Meinik had told them there was a staircase above blocked with stones, it had seemed so impossible, to him, to clear it that he had placed no stress upon the fact; and the preparations made by the enemy to cut off any possible retreat had greatly depressed them.

Stanley took one of the iron ramrods and, raking some of the embers from the fire, placed it in them, about a foot from one end; then he directed the others to fan the embers, until they raised them almost to white heat. Taking the ramrod out, he laid the edge of one of their knives upon it and, striking its back with a stone, soon cut through the glowing rod. He repeated the operation and had, then, three short rods of equal length. He now heated one end of each and, laying it on an axe on the ground, hammered it into chisel shape with the back of a light hatchet; repeating this several times, until it had the required shape and sharpness; then he plunged this into a pot of water. He did the same with the other two; and had, now, three chisels with which he hoped to be able to chip away the stones. The other ramrod he left intact, except that he sharpened one end.

Then, going up to Harry's room, he lay down and slept for some hours; putting the two boys on watch, and bidding the trooper look after them. The two Burmans, with one of the guards, were to go to work with him. Several times he woke. The last time, on looking out, he thought that there was a faint light in the sky and, going down, called up the three men and, bidding them bring up the two heavy axes, a light hatchet, and the three short chisels, he led them up the steps to the working party.

"How have you got on, Meinik?"

"We have cleared four feet, master; but there is a big stone sticking up, now, and we can do nothing with it."

"We will have a try, and do you all go down, at once.

"Take off your cloth, one of you, and fill it with this rubbish on the steps. Do it as quickly as you can. The day will be breaking, in a few minutes."

Stanley now climbed up, and investigated the pa.s.sage. The bottom was level. Every crack and crevice between the stones being filled up with rubbish. The obstacle Meinik had spoken of evidently formed part of a flat slab. It reached within an inch of the roof and, at one side, touched the rock wall; at the other there was an interval, of some four or five inches, and the earth and rubbish had already been sc.r.a.ped out from behind it. Putting his hand in, he found that the block was some four inches in thickness.

He thought that if he could but get a fair blow at it, with the back of one of the heavy axes, he might break it off; but this was impossible. The total width of the pa.s.sage did not exceed three feet; and as the men had, as they went, worked down somewhat, there was now about thirty inches between the bed of earth and rubbish, on which he was lying, and the roof. Taking the handle of the axe in both hands, he used the head as a battering ram; but without any success. He then called up the slightest of the three men, and told him to crawl in beside him and, with their united strength, they pounded the stone for some time. Finding that nothing could be done this way, Stanley sent the man back again; and then, taking one of the three chisels and a small hatchet, he proceeded to mark a line along the bottom of the stone; and then, for ten minutes, worked away on it with the chisel and hammer. Then he called up one of the others, and showed him what he was to do. All day they worked by turns and, though progress was very slow, by nightfall the groove was half an inch deep.

Stanley and the strongest Burman then went in together and, lying on their backs again, tried the effect of the heavy axe; but still without success. Then Stanley told the man to get down and take out the wedge, at the top of the axe; and to cut away the wood below the head, so that the latter would slip down, four or five inches; then to take off the head of the other heavy axe and put it on above it, and replace the wedge. In a few minutes, the man rejoined him.

"We must strike it as near the roof as we can," Stanley said. Both grasped the handle firmly. "We will sway it backwards and forwards three times and, the third time, strike.

"One, two, three--hooray!"

As the two-headed axe, driven with their united force, struck the stone, there was a sharp crack.

"That has done it," Stanley said, turning over.

There was a dark line along the groove, and the top of the stone inclined back, two inches from the perpendicular; being kept in its place by the rubbish behind it. Stanley put his hand into the hole, and got his fingers behind the stone; while the Burmese put the chisel into the crack, and used it as a lever. In two or three minutes the stone was moved out of its position, taken out of the hole, and laid down on the steps.

Half an hour later Meinik came up, with a trooper, another guard, and one of the boys; and was delighted to find that the obstacle, which had seemed to him fatal to their hopes, had been removed.

Stanley showed how they had carried out the work; and then, with his party, went down into the rock chambers.

"It was pretty tiring work, Harry," he said, "though we were only at it about a quarter of an hour, at a time. My wrists and arms and shoulders are aching, as if I had been beaten with sticks. Tomorrow I will take up a good supply of firewood. The chisels got blunted before we had worked an hour; and we should get on a deal faster, if we could sharpen them frequently."

"Is the stone hard?"

"No; it is a sort of marble, I think. We had the underpart of the slab on our side, and I did not think of looking when we took it down. Anyhow, it was not very hard and, with a good strong chisel and a short, heavy hammer, I am sure we could have done it in an hour.

"Anyhow, it is a comfort that nothing came down on top of us. I examined the pile carefully, and there had not been the slightest movement among the lower stones; so that part of the difficulty seems to have been got over.

"Now, I must go down and get something to eat, and then I will go in for a good sleep. You are feeling all right, I hope?"

"Could not be doing better, Stanley. I have eaten three solid meals, today; and have been sitting up on the edge of my bed, for some time. I tried standing, but it was no go; still, I do think that, in a day or two, I shall manage it."

For six days the work continued. One party watched, another slept, and the third worked, by turns. Some of the stones gave much greater trouble than the first they had met with; but having the fire close by proved a great a.s.sistance, as the chisels could be frequently sharpened. The men became more accustomed to the work, and the steady progress they made greatly excited their hopes.

At the end of the week, but one stone barred the way. This, however, was much the most formidable that they had encountered. It seemed to have been a pillar, or a huge gate post; and was square, measuring some twenty inches on each face. The obstacle was all the more formidable, as the upper end was inclined towards them, greatly increasing the difficulty in using the chisel. Beyond this, as far as they could see, there was merely a ma.s.s of smaller stones.

The party who had been working upon this block were much disheartened, when Stanley went up to relieve them. Owing to the inclination of the stone, their chisels could get but little bite and, though they had been working for six hours at it, they had scarcely made any impression; indeed, at only one point had they so far broken the face that the chisel would cut. Meinik had come down two hours before, to report to Stanley the nature of the obstacle and, when he went up, he took with him the second ramrod, which had not hitherto been used.

He saw at once that, as Meinik had told him, it would be impossible to get through this block by the same means as before for, as the groove deepened, the labour would become greater and greater and, from the inclination of the stone, they would in time arrive at a point where the axe could no longer be used to strike the chisel.

The point at which the slight indentation had been made was nearly at the corner of the stone. This was gradually enlarged, by hammering upon it with the head of the axe and, after an hour's work, the surface had been so far pounded that the chisel could get a flat hold upon it. Then Stanley and one of the Burmans lay down, and placed the cutting end of the long ramrod against it; and the others, by turns, struck the end with the back of a light hatchet, those holding the rod turning it, slightly, after each blow. Every half hour the edge of the chisel was resharpened and, by the time the next party relieved them, a hole of half an inch in diameter, and two inches deep, had been drilled in the stone. Stanley remained with the newcomers for half an hour, instructing them in the work, and then went below.

"Well, Stanley, what are you going to do with this monstrous stone Meinik tells me of?"

"There is only one thing to do with it, Harry; that is, to blast it. The block is so inclined that one can do nothing with the chisels, and we are now drilling a hole. I don't know that I shall succeed but, at any rate, I am going to have a try. If it fails, I must hit on some other way. The provisions are holding out all right; and Meinik calculates that, with a little stinginess, we could manage for another three weeks. We have drilled the hole in two inches today and, as we get more accustomed to the work, I dare say we could do three inches in each shift. The block is twenty inches through on the straight, and may be two feet on the line that we follow; so that in four days we shall be nearly through it.

"In three weeks we shall have made five holes, which will weaken it so that we may be able to break it off. However, I hope we shall find one hole sufficient. I shall make it fifteen inches deep, and then charge it with the contents of a dozen cartridges. I think that ought to do it."

In two days and a half, the hole was of the required depth. Harry had progressed so rapidly that he was able, that morning, to walk across his room.

"We must try the shot, at once," Stanley said, "because if it fails, we must go on working. If it succeeds we can, if we like, wait for another week before we make off. By that time you will be strong enough to be got through that low pa.s.sage, and walk for a little distance; when we can cut some poles, and rig up that hammock again.

"Do you know anything about mining, for I know nothing? I only had an idea how to drill the hole from seeing some engineers at work at Agra, years ago; but I am sure I don't know how they fired the shot, or prepared it."

"I can tell you a little about it, Stanley; for I have been down a coal mine once or twice, and watched the men doing it. They first of all put in the charge; then they put in a wooden rod, just the thickness of the fuse they use; then they dropped in a little dry dust round it, which they pressed down very carefully, with a small wooden rod; then they damped some dust, and hammered that down hard. After putting in about half an inch of this, they used dust slightly moistened, beating it down as before. When it was quite full, they pulled out the centre stick, and put the fuse into the hole that it left."

"We have not got any fuse," Stanley said, "but I think that if we take a narrow strip of cloth, moisten it, and rub gunpowder into it; let it dry, and then roll it up, it would be all right. Then we could lay a train of damp powder to it, set the end alight, and bolt."

"I should think that that would do," Harry agreed, "but you would have to bolt very sharp for, if it went off before you got to the bottom of the steps, it might be very awkward."

"I don't think the effect of the shock will be as great as that, Harry. It may crack the stone, but I should hardly think it would send anything flying out of the hole."

Chapter 16: Rejoining.

Every day, since the siege had begun, the defenders had fired an occasional shot at the stockade; not with any idea of doing any damage, but in order that the a.s.sailants should know that they were still in the cavern. That evening, when the hole had got to the proper depth, Stanley, having prepared his fuse, went up with twenty cartridges in his pocket, accompanied by Meinik. The hole was charged and tamped, and the fuse inserted. This took a considerable time. The fuse had been cut so that an inch of it projected outside the hole. The other eight cartridges were then broken up, and the powder moistened; and a train some two feet long laid, from the fuse towards the entrance of the hole. Then a piece of rag was wrapped round one end of the ramrod; and this, again, was tied to a long rod that had, the night before, been cut by one of the boys, who had slipped out noiselessly from the entrance. The rag had been moistened, and rubbed with gunpowder.

"Now, Meinik," Stanley said, "everything is ready. This rod is sixteen feet long, so that, lying down, my feet will be just at the edge of the hole; and I shall be able to drop down, as soon as I have lighted the train, and bolt. I shall fix a torch, a foot or so from the train; then I shall only have to lift the rod to it, light the rag, set fire to the train, and then slide down and bolt.

"Now, you must go down first."

"No, master," Meinik said firmly; "I will light the train. I do not think that there is any danger but, whether there is or not, I shall undertake it. If I am killed, it does not matter; while if you were killed all would be lost for, if the explosion did not burst the stone, I am sure that we should never be able to get through it, without you to direct us. No, master, if you stay, I stay; and that would only lessen our chances of running down the steps in time."

Stanley argued, and even ordered, but Meinik was obstinate and, seeing that the faithful Burman was not to be moved, he reluctantly left the matter in his hands, and went downstairs. He moved a short distance along the ledge, and waited. The time seemed an age to him, so that he gave an exclamation of delight when Meinik suddenly came into sight, and took his place beside him.

"I have lit the train, master. The powder fizzed up, but did not seem to burn very fast."

It was, indeed, another two minutes before a deep m.u.f.fled roar was heard. There was no further noise, but they heard shouts from the Burmans, behind the stockades.
