"The last time the English came, they captured Nundidroog, and other hill fortresses that we had regarded as impregnable, simply because the governors were overconfident, and the defences had been neglected. This must not occur again, and if there is failure in the defences, I shall hold you responsible. Therefore, take care that you do not neglect, not only to see that the repairs are being well carried out, but to recommend additions to the fortifications, wherever it seems to you that there is even a possibility of an enemy making his way up. "You will take with you twenty troopers as an escort, but these are not to enter any of the fortresses with you, for treachery is always possible; and no one, save the garrisons, must be acquainted with the defences of the hill forts." Surajah expressed his thanks to the sultan for entrusting them with the mission, and assured him that their inspection of the forts should be careful and complete, and that they would start in an hour's time. When they reached their own room, Dick threw up his turban in delight. "Was there ever such a stroke of good fortune?" he exclaimed. "The tiger business was as nothing to this. Tippoo has given us the mission, of all others, that will enable us to carry out our search. Our work is as good as done. "That is to say," he added, more gravely, "we are at least pretty sure to find my father out, if he is alive. Besides, we may get information that will be of great use, if the war is renewed. "Now we had better, in the first place, go and see Fazli and get our instructions. We will order our horses to be in readiness to start, as soon as we have had our meal--we may not get another chance of eating today. "I should like to take Ibrahim with us. He is a capital servant, and a strong, active fellow. I believe he is fond of us, and we shall want someone who can cook for us, and buy things, and so on. I will speak to Fazli about it." The chamberlain looked up, as they entered the room where he was engaged in dictating to a clerk. "I congratulate you on your mission," he said. "It will involve a great deal of hard work, but as you have told me how you longed for some duty outside the Palace, you will not mind that. Tippoo consulted me before sending for you. I told him you were diligent in the service, and I felt sure you would do your best in the present matter; and that, as you were accustomed, in the pursuit of game, to ascend mountains and scale precipices, you were far more likely to find the weak spots in the forts than an old officer, who would be likely to take everything for granted.
