"And what's to be done next, Mister Charles? That's Hossein, sure enough, but it don't bring us much nearer to getting out."  
"The first thing is to communicate with him in some way, Tim."
 
"If he'd come up to the side of the moat, yer honor might spake to him."
 
"That would never do, Tim. There are sure to be sentries on the walls of the prison. We must trust to him. He can see the sentries, and will know best what he can do."
 
It was evident that Hossein did not intend doing anything, at present; for, still stooping and gathering brushwood, he gradually withdrew farther and farther from the wall. Then they saw him make his sticks into a bundle, put them on his shoulder, and walk away. During the rest of the day, they saw no more of Hossein.
 
"I will write," Charlie said, "--fortunately I have a pencil--telling him that we can lower a light string down to the moat, if he can manage to get underneath with a cord which we can hoist up, and that he must have two disguises in readiness."
 
"I don't think Hossein can read," Tim said, "any more than I can, myself."
 
"I daresay not, Tim, but he will probably have friends in the town. There are men who were employed in the English factory at Kossimbazar, hard by. These will be out of employment, and will regret the expulsion of the English. We can trust Hossein. At any rate, I will get it ready.
 
"Now the first thing we have to do is to loosen one of these bars. I wish we had thought of doing it before. However, the stonework is pretty rotten, and we shall have no difficulty about that. The first thing is to get a tool of some sort."
 
They looked round the room, and for some time saw nothing which could in any way serve. The walls, floor, and wide bench running round, upon which the cushions which served as their beds were laid, were all stone. There was no other furniture, of any kind.
 
"Divil a bit of iron do I see in the place, Mister Charles," Tim said. "They don't even give us a knife for dinner, but stew all their meats into a smash."
 
"There is something, Tim," Charlie said, looking at the door. "Look at those long hinges."
 
The hinges were of ornamented ironwork, extending half across the door. Upon one of the scrolls of this ironwork they set to work. Chipping a small piece of stone off an angle of the wall, outside the window; with great difficulty they thrust this under the end of the scroll, as a wedge. Another piece, slightly larger, was then pushed under it. The gain was almost imperceptible, but at last the piece of iron was raised from the woodwork sufficiently to allow them to get a hold of it, with their thumbs. Then, little by little, they bent it upward; until at last they could obtain a firm hold of it.
 
The rest was comparatively easy. The iron was tough and strong but, by bending it up and down, they succeeded at last in breaking it off. It was the lower hinge of the door, upon which they had operated, as the loss of a piece of iron there would be less likely to catch the eye of anyone coming in. They collected some dust from the corner of the room, moistened it, and rubbed it on to the wood so as to take away its freshness of appearance; and they then set to work with the piece of iron, which was of a curved shape, about three inches long, an inch wide, and an eighth of an inch thick.
 
Taking it by turns, they ground away the stone round the bottom of one of the bars. For the first inch, the stone yielded readily to the iron; but below that it became harder, and their progress was slow. They filled the hole which they had made with water, to soften the stone, and worked steadily away till night; when, to their great joy, they found that they had reached the bottom of the bar. They then enlarged the hole inwards, in order that the bar might be pulled back. Fortunately, it was much decayed by age; and they had no doubt that, by exerting all their strength, together they could bend it sufficiently to enable them to get through.
 
At the hour when their dinner was brought they had ceased their work, filled up the hole with dust collected from the floor, put some dust of the stone over it, and smoothed it down, so that it would not have been noticed by anyone casually looking from the window.
 
It was late at night before they finished their work. Their hands were sore and bleeding, and they were completely worn out with fatigue. They had saved, from their dinner, a good-sized piece of bread. They folded up into a small compass the leaf from his pocketbook, upon which Charlie had written in Hindostanee his letter to Hossein, and thrust this into the centre of the piece of bread. Then Charlie told Tim to lie down and rest for three hours, while he kept watch; as they must take it in turns, all night, to listen in case Hossein should come outside. The lamp was kept burning.
 
Just as Charlie's watch was over, he thought he heard a very faint splash in the water below. Two or three minutes later, he again thought he heard the sound. He peered out of the window anxiously, but the night was dark, and he could see nothing. Listening intently, it seemed to him, several times, that he heard the same faint sound.
 
Presently something whizzed by him, and looking round, to his delight he saw a small arrow, with a piece of very thin string attached. The arrow was made of very light wood. Round the iron point was a thick wrapping of cotton, which would entirely deaden its sound, as it struck a wall. It was soaked in water, and Charlie had no doubt that the sound he heard was caused by its fall into the moat, after ineffectual trials to shoot through the window.
 
Round the centre of the arrow a piece of greased silk was wrapped. Charlie took this off, and found beneath it a piece of paper, on which was written in Hindostanee:
 
"If you have a bar loosed, pull the string and haul up a rope. If not, throw the arrow down. I will come again, tomorrow night."
 
Tim had by this time joined Charlie, and they speedily began to pull in the string. Presently a thicker string came up into their hands. They continued to pull, and soon the end of a stout rope, in which knots were tied every two feet, came up to them. They fastened this to one of the bars, and then took hold of that which they had loosened; and, putting their feet against the wall, exerted themselves to the utmost. The iron was tougher than they had expected, but they were striving for liberty and, with desperate exertions, they bent it inwards until, at last, there was room enough for them to creep through.
 
"Can you swim, Tim?"
 
"Not a stroke, yer honor. Shure you should know that, when you fished me out of the water."
 
"Very well, Tim. As I kept you up then, 'twill be easy enough for me, now, to take you across the moat. I will go first, and when I get into the water, will keep hold of the rope till you come down. Take off your boots, for they would be heard scraping against the wall. Be sure you make as little noise as possible, and lower yourself quietly into the water."
 
Charlie then removed his own boots, squeezed himself through the bars and, grasping the rope tightly, began to descend. He found the knots of immense assistance, for had it not been for them, unaccustomed as he was to the work, he would have been unable to prevent himself from sliding down too rapidly. The window was fully sixty feet above the moat, and he was very thankful when, at last, he felt the water touch his feet. Lowering himself quietly into it, he shook the rope, to let Tim know that he could begin his descent.
 
Before Tim was halfway down, Charlie could hear his hard breathing, and muttered ejaculations to himself:
 
"Shure I'll never get to the bottom at all, my arms are fairly breaking. I shall squash Mr. Charles, if I fall on him."
 
"Hold your tongue, Tim," Charlie said in a loud whisper.
 
Tim was silent, but the panting and puffing increased, and Charlie swam a stroke or two away, expecting every moment that Tim would fall. The Irishman, however, held on; but let himself into the water with a splash, which aroused the attention of the sentry above, who instantly challenged.
 
Tim and Charlie remained perfectly quiet. Again the sentry challenged. Then there was a long silence. The sentry probably was unwilling to rouse the place by a false alarm, and the splash might have been caused by the fall of a piece of decayed stone from the face of the wall.
 
"Tim, you clumsy fellow," whispered Charlie, "you nearly spoiled all."
 
"Shure, yer honor, I was kilt entirely, and my arms were pulled out of my sockets. Holy Mother, who'd have thought 'twould be so difficult to come down a rope! The sailors are great men, entirely."
 
"Now, Tim, lie quiet. I will turn you on your back, and swim across with you."
 
The moat was some twenty yards wide. Charlie swam across, towing Tim after him, and taking the greatest pains to avoid making the slightest splash. The opposite side was of stonework, and rose six feet above the water. As soon as they touched the wall, a stout rope was lowered to them.
 
"Now, Tim, you climb up first."
 
"Is it climb up, yer honor? I couldn't do it, if it was to save my sowl. My arms are gone altogether, and I'm as weak as a child.
 
"You go, Mister Charles. I'll hould on by the rope till morning. They can but shoot me."
 
"Nonsense, Tim! Here, I will fasten the rope round your body. Then I will climb up, and we will pull you up after me."
 
In another minute, Charlie stood on the bank, and grasped the hand of his faithful follower. Hossein threw himself on his knees, and pressed his master to him. Then he rose and, at a word from Charlie, they hauled Tim to the top. The rope was taken off him and, noiselessly, they made their way across the country. Not a word was spoken, till they were at a considerable distance from the fort.
 
"Where are you taking us, Hossein?" Charlie asked, at last.
 
"I have two peasants' dresses, in a deserted cottage a quarter of a mile away."
 
Not another word was spoken, until they reached the hut, which stood at the end of a small village. When they had entered this, Charlie first thanked, in the warmest terms, his follower for having rescued them.
 
"My life is my lord's," Hossein answered simply. "He gave it me. It is his again, whenever it is useful to him."
 
"No, Hossein, the balance is all on your side, now. You saved my life that night at Ambur. You saved it that night at Calcutta, for, without the water you brought us, I question whether we could have lived till morning. Now you have procured our freedom. The debt is all on my side now, my friend."
 
"Hossein is glad that his lord is content," the Mohammedan murmured. "Now, what will my lord do?"
 
"Have you any place in the town to which we could go, Hossein?"
 
"Yes, Sahib. I hired a little house. I was dressed as a trader. I have been here for two months, but I could not find where you were confined, although I have tried all means, until I saw your cap."
 
"It was foolish of me not to have thought of it before," Charlie said. "Well, Hossein, for a little time we had better take refuge in your house. They will not think of searching in the city; and, as Calcutta is in their hands, there is nowhere we could go. Besides, I must discover, if possible, where Miss Haines is kept a prisoner; and r............
