On the top of the rock there was a platform of considerable extent, its edge forming a natural rampart, which was a perfect defence against the negroes, with their barbaric weapons. Of course it would be of little consequence against artillery; but there is not the remotest chance of artillery being brought to bear against it, for the simple reason that the natives have nothing of the kind, and no knowledge of the processes of working metals beyond that of smelting iron-ore and shaping it into spear-heads and the like. A soldier was on duty on the top of the rock, with instructions to report any approach of caravans, or even of small groups of men, from whatever direction. The arrival of the escort from Gondokoro made quite a sensation among the members of the garrison, and those who received permission came out on the road to meet the new-comers; in fact, everybody had left except the sentinel on the summit and the men who had been detailed to relieve him, and Frank thought, under the circumstances, it would not have been hard work for him to take the fort, with Abdul's assistance, and keep it for his own use. But he wisely considered that he would not know what to do with a fort if he had one. It would be worse than a "white elephant" on his hands, and so he gave the matter no farther thought, and let the stronghold of Fatiko remain in Egyptian hands. Frank ascertained that the fort was 3587 feet above the level of the sea, and about 300 feet higher than the flat country, which began a few miles farther on. Captain Mohammed told him that from that point to the Somerset River the region was sparsely settled, and they would not encounter many natives. There was no reason to fear hostilities, though it was reported at the post that the King of Unyoro was at war with one of his neighbors, and the difficulties between these native monarchs might possibly make travelling a trifle unsafe. "The King of Unyoro," said the captain, "is friendly to nobody; he is treacherous to strangers as well as to neighbors, and, while professing friendship, is quite likely to be plotting your ruin. He has been taught several severe lessons, which have made him more respectful, though no more friendly, than before. "Speke and Grant were detained some time in Unyoro, and were obliged to use considerable strategy to get away when they did. Since their visit a new king is on the throne, but he is much like the former one, though not so great a beggar. The old king compelled Speke to give him his watch and chain, and many other things of his personal belongings, in addition to the presents they had brought him as tribute to an African ruler."
