"Yes, that will give me plenty of time. Let me see. There is the short ladder to make. That won't take me over an hour. There are a hundred bits to cut for the long ladder, putting them about two feet apart. That will be a longish job, for the spear shafts are of very tough wood. However, I have a saw, and some oil, which will prevent it making a noise, and can make fairly quick work of it. I have several tools, too. I very often do carpentering jobs of all sorts--that is what first made the governor take to me. I can get all that part of the work done today. Tonight I will do the knotting. Of course, I shall make it a goodish bit over two hundred feet long, for it may turn out that I have not judged the depth right, and that the cliff is higher than I thought it was. "I don't think sawing up the spear shafts will take more than an hour or two, so I shall be able to show myself about the place as usual. I will go over and take a good look at the rock again, and stick a spear head into the ground, at the point where it seems to me that it goes down straightest, and where there is the least chance of the rope getting rubbed against a sharp edge. I sha'n't begin at the wall until tomorrow, for I don't suppose I shall be able to get out the first few stones without making a bit of a noise, and it would not do to work at night. "Now, lad, I think we can consider that as all settled, and I won't come near you again, unless there is some change of plan. I shall be here tomorrow evening, I hope it will be by ten o'clock--that must depend upon how long it takes me to get down the outside layer of stone. "If you should hear a sudden row, make at once for the wall behind the governor's house, and wait there for me to join you. You see, some of the stones may come down with a run, and if they do I shall give the rest a shove, and be out like a shot. I shall hear which side the sentry is running round the house, and shall belt the other way. Of course, he will see the stones and give the alarm; but in the darkness, I have not much doubt of being able to slip away, and I will then make my way straight to the wall. Of course, I shall have the ladders tied up into bundles, and shall take care not to leave them behind me." "All right, Father. We will be ready tomorrow evening. We shall wait quietly for you until you come, unless we hear a sudden alarm. If we do, we will go round behind the governor's house, and wait there for your coming." "That is it, my lad. Now I will be going. I am glad that no one has come in while I have been here." Chapter 20: The Escape.
