This time Bob went off fast asleep; his cap fell on to the deck, but it did not disturb him; and he was evidently making up for lost time, when a very industrious spider, who had made his home in the awning, came boldly out of a fold by a seam of the canvas, and with busy legs proceeded to examine the state and tension of some threads, which it had previously stretched as the basis of a web upon a geometrical plan, expressly to catch mosquitoes. Apparently satisfied, the spider set to work busily, its dark, heavy body showing plainly against the yellowish canvas; and in a very short time a main rope was attached to the roof, and the architect of fly-nets began slowly to descend, in search of a point to which the other end of the said main-stay could be attacked. Now fate had so arranged it, that the point exactly beneath the spider as it slowly descended was the tip of Bob Roberts' nose, and to this point in the course of a minute the insect nearly arrived. It may be thought that its next act would be to alight and fix its rope; but this was not so easy, for the soft zephyr-like breaths the middy exhaled drove the swinging architect to and fro. Now it came near, now it was driven away; but at last it got near enough to grasp at the sleeper's most prominent feature, just brushing it with its legs, and setting up an irritating tickling that made Bob snort and scratch his face. The spider swung to and fro for some seconds, and then there was another terrible tickle, to which Bob responded by fiercely rubbing the offending organ. The spider was driven to a distance by this; but it was back again directly, with its legs stretched out, tickling as before. Bob was not asleep, and he was not awake, and he could neither sink into oblivion, nor thoroughly rouse himself. All he could do was to bestow an irritable scratch at his nose, and the spider came back again. At last, spider or no spider, he dropped into a strange dreamy state, in which he believed that Tom Long came and loomed over him on purpose to bend down and tickle him, out of spite and jealousy, with the long thin feather from a paroquet's tail. "Don't! Bother!" said Bob, in his sleep; but the tickling went on, and he felt ready to leap up and strike his tormentor; but he seemed to be held down by some strange power which kept him from moving, and the tickling still went on. Then he could hear voices talking, and people seemed to be about, laughing at and enjoying the trick that was being played upon him; and then he started into wakefulness, for a voice exclaimed,-- "Come, Mr Roberts, are you going to wake up?" It was Lieutenant Johnson who spoke; and on the middy jumping up, he found standing by him, with the lieutenant, the dark-faced youth who had met them and acted as guide on the occasion when they made their first visit to the sultan's home.
