"No leopard, sah; leopard no make nize."

"What is it, then?"

"Dere he are, sah! Dat him! Big amalua, sah!"

They had just reached the water's edge. Away to the left, sousing himself in the running stream, they saw a splendid elephant, with gleaming tusks that would have brought joy to a hunter's soul. Tom would have tried a shot, if he had not already proved that his rifle was hopelessly antiquated and short-ranged, and with his present responsibility he did not feel justified in running any avoidable risks. He sighed, and passed on, over a bridge of tree-trunks cleverly bound together by ropes made of papyrus and creepers. It had evidently been slightly repaired for the passage of the British force, some of the plant-ropes looking fresh and new.

On the other side of the stream came another stretch of fairly level country, with short, straw-coloured grass, interrupted here and there by a swamp. By half-past five Tom calculated that they had covered no more than twenty miles, and he was uncomfortably conscious of his want of training. He had a drawn, burning sensation at the ball of his left foot, and felt pretty sure that he would find there the making of a blister. Luckily, just before sundown they came to a banana plantation, amid which, on a knoll, stood a very neat and tidy-looking hut. It happened to be empty, and Tom thought it no wrong to the absent owner to make it his quarters for the night. There were a few rough clay utensils in it, and Mbutu, fetching water from the brook which ran round the base of the knoll, soon made some tea, which, with bananas cut fresh, millet cakes, and oatmeal biscuits, furnished a satisfactory supper. Tom bathed his feet, and at Mbutu's suggestion covered them with a compress of bananas. In the morning he found, rather to his surprise, that this novel application had been most beneficial. It was only one of the hundred uses to which, as he learnt by degrees afterwards, the natives put the plant: its pulp made flour and beer, spirits and soap; its rind made plates and dishes and napkins; while its stalks provided pipes, and even material for footbridges.

Next day they started at sunrise. Walking was more arduous than it had been on the previous day, for the ground rose gradually, becoming more and more rocky, cut at intervals by ravines, and showing here and there fragments of what Tom believed must be lava. The soil was in truth volcanic; not very many miles to the south of their path stood two volcanoes still moderately active, and but a few miles north there were mountain lakes lying hidden in the craters of volcanoes long extinct. Tom knew nothing of these, however; he was only concerned with the hard fact that walking was unpleasant, and that over the rocky ground the track of the expedition was sometimes difficult to discover. The one consolation was that, slow as their own progress was, the progress of the expedition, as the Zanzibari porters carried their loads over ravine and boulder, must necessarily be slower. Foot-sore, aching in every limb, he nevertheless pressed on indomitably, hoping against hope that he might overtake his uncle before night. But though he anxiously looked ahead through his field-glass, he saw nothing but broken, rocky country, and at five miles' distance his view was interrupted altogether by a rugged line of hills.

The sun went down in crimson splendour. There was no hut on this occasion to afford sleeping room to the weary travellers. Building a fire with some wood from a scanty copse on the bank of a ravine, they found a shelter hard by among the rocks, and slept in their rugs. Up again at day-break, they pushed on, and were pleased to find, on reaching the range of hills before mentioned, that the ground there sloped gradually downwards, and the path led once more into a grassy plain. Just before noon, after crossing a bridge, evidently new, thrown over a wider stream than any they had yet encountered, and walking up a steep grassy acclivity, Tom raised his glass to his eyes, and uttered an exclamation of thankfulness and joy.

"There they are, Mbutu!" he cried. "I see them! It must be the expedition. It's just like a long snake winding through a broad defile over there. Look! Now isn't it?"

Mbutu peered long and earnestly into the distance.

"Right, sah! I see dem big black man. Dey plenty big, plenty strong. Soon be dar, sah; see sah him uncle."
