IN TOILING BY TANGANYIKA. N the article entitled "To Usumbara and Back," I tried to sketch our first experiences on the African Continent. I now propose to transport the readers of GOOD WORDS, by the magic power of the pen, into the very heart of Africa, and to give some glimpses of our movements by the shores of Lake Tanganyika. Before reaching this point in our journey we have traversed hundreds of unexplored miles, and seen many strange tribes, not without manifold fracas, dangers, and troubles, which met us in a thousand shapes. But from the fiery ordeal we have passed unscathed, with one great and irreparable exception. Our gallant and enthusiastic leader has fallen a victim in the attempt to break through the barriers of disease and barbarism which make the interior of Africa almost impenetrable, and his name is added to the long and honoured list of geographical martyrs. Among the swamps of Uzaramo and the Rufiji valley Mr. Keith Johnston met his fate; and he sleeps in the primeval forest of Behobeho, where his grave is now green, as his memory ever will be. But though his presence was taken from us his spirit went with us. Like the mantle of Elijah, his enthusiasm for the work of research was left behind him; and I, though young and inexperienced, resolved to carry out his designs. Resuming our march, then, under these new conditions, we pushed rapidly on through the remaining part of the malarious low-lying country, over which a shadow of death seems ever to hang. Crossing the range of mountains which bounds the great central plateau, we traversed Uhehe, with its bleak, monotonous moorlands, its cutting east winds, and its gentlemanly, warlike savages. We next as I. cended to a second and higher plateau, where we met with a tribe of squinting natives. At last we reached the edge of the mountains which bound the north end of Nyassa; and there, several thousand feet below us, lay the undulating waters of the lake. Here commenced the second section of our work. Passing through the charming country of Makula, with its pleasant Arcadian scenes, we traversed the hitherto unexplored region between the north end of Lake Nyassa and the south end of Lake Taganyika. And now, when our story begins, the East Central African Expedition stands by the shores of the latter lake on the 3rd of November, 1879. It is a proud moment for all of us; and, like boisterous school-boys, we give free vent to our delight. Down go the loads, and with shout and song a ring is formed of energetic dancers, who literally plough up the ground as if they were shod with iron, while the woods and rocks re-echo with the thunders of their guns. With the waves of the lake rippling at our feet, the roll is called; and as each sonorous name is uttered, a cheerful "Eh Wallah” (Here, Sir!) is returned, until the list is finished. Out of the one hundred and fifty men who had left the Indian Ocean there was not one absent. Neither desertion nor death had deprived us of a single porteran occurrence unique in the history of African travelling. Tanganyika was the terminus of the route marked out for us by the Royal Geographical Society. Our appointed work was thus finished, and we might with all honour have returned once more to the comforts of civilisation and the joys of home. But an irresistible impulse within me forbade the thought. The sight of that glorious lake, with its en- ment stood a white man!

At one side a point of land extended into the water, like a huge quay, rising to a height of three hundred feet in sheer rocky precipices, and topped by a covering of trees. Over this could be discerned a bay, surrounded by picturesque and almost perpendicular mountains, three thousand feet in height. On the opposite or eastern side the shores rose less abruptly, but in great inclined steps, till they culminated in the magnificent Lambalamfipa Mountains, eight thousand feet above the sea, the whole being clothed with a dense and uniformly green vegetation. At our feet dashed a delightful clear stream, lined with luxuriant trees and tangled creepers. In front lay the lake in expansive beauty, with its broken shore-lines and threatening walls of rock, here sweeping round in a fine bay, there forming a miniature fjord, while the scene was further varied by capes and islands, like emeralds set in a sea of glass. learned that he was no such unwelcome emissary, but an excellent lay missionary from Livingstonia at the south end of Lake Nyassa, who had come to explore the country between the two lakes, and who for several days had been following my footsteps. The day after our arrival we proceeded to that classic spot where Livingstone had first seen the lake, namely, Pambete. Here, after his weary and arduous wanderings from the south end of Lake Nyassa, he arrived half-dead with hard fare and malignant fevers, to rest for six weeks among the friendly and hospitable natives. The effect of such a meeting upon me after my long weary months of isolation from civilised society, cannot be expressed in words. With breathless interest I hung on every word he had to tell of the latest European affairs, and I began to feel as if I had got a new lease of life, so invigorated did I find myself. Pambete we found to be very much altered since the days in which Livingstone visited it. Then it was a thriving and prosperous village, with its well-cultivated fields, its oil palms. and busy fisheries. Now it has almost dwindled out of existence. The huts are deserted except by a few old men and innumerable rats. The oil palms seem to have been destroyed, and there is little fishing in the lake. At The scenery around Pambete is picturesque in the extreme. The village occupies a niche in the surrounding mountains, and over their rugged red sandstone cliffs the River Eisè falls in a beautiful cascade. their base is a small plain, formed by the As was the case with Livingstone, I was detritus brought down by the stream, and extremely reduced by fever on my arrival at in the dense jungles and forests which cover Pambete, and I therefore resolved to have ait buffaloes roam unmolested. In front is few days' rest to recruit. On the fifth, while lying in a native hut musing over my plans for future action, I was much surprised to hear a stange hubbub. Yelling and shouting and firing of guns suddenly became the order of the day. Think ing that the village had been attacked by some enemy, I rushed hastily out of the hut, gun in hand; and there to my infinite amaze the lake, with its broken outline and little islands. The place, however, is entirely unhealthy. It is a perfect oven, where the wind rarely enters, and, from the swampy surroundings, a malaria ever seems to hang over it. It may be a romantic, but it is by no means a desirable residence. During our stay here I ran a narrow escape of being caught by a crocodile. According to my usual custom I went out one morning to enjoy a good splash in the lake. Wading out a considerable distance, but not out of my depth, I observed what appeared to be a log of wood floating a short distance from me. Taking no notice of this I went on laving the cool water over myself. Looking up after a few minutes I observed that the apparent log had floated nearer to me. Noting it more closely, I made out the outlines of a crocodile's head, with its ugly snout, wrinkled skin, and glittering eyes. I stood for a moment aghast at the sight, for I was a considerable distance from the shore, and still it came nearer. Regaining my presence of mind, I made the welkin ring with a shout of "Mambo! Mambo!" (crocodile). The cry instantly brought my men with their guns to the water's edge, and they seeing my imminent danger and desperate efforts to reach the shore, rushed in in a body to meet me, making the waters boil. When they reached me the crocodile was within a few feet and would have seized me in another minute. But seeing the porters in such numbers, yelling and shouting, and firing their guns, it evidently thought that an empty stomach was better than a feast of bullets, and wisely disappeared. If I had been out of my depth at the time my chance of surviving the rencontre would have been a poor one. Half-recovered from a sharp attack of fever, I prepared to continue my journey northward, while Mr. Stewart retraced his steps. On the tenth of November we separated on our different roads-I for Lukuga, he for Nyassa. Crossing the river Eisè, we commenced the ascent of the bordering precipices of the lake. The first part of my way led up an extremely rocky talus of fallen rubbish, where we had to jump from boulder to boulder like so many goats. As we as cended, the path became steeper and more rugged, till hands and knees had to be employed-the men alternately putting up their loads on some resting place above them, and then clambering up themselves. Half-way up the ascent a sad spectacle met our eyes—a chained gang of women and children. They were descending the rocks with the utmost difficulty, and picking their steps with great care, as, from the manner in which they were chained together, a fall meant dislocation of the neck. Truth compells me to say that this was the first slave caravan I had yet seen in Africa, though I had heard of a number which had kept out of our path for fear of our liberating the slaves. But, though it was the first, it ex- It was out of the question to attempt releasing them. The most I could do was to stop them and give the little things such a feed as they had not had for weeks. The rascally leader came fawning up to me: but I gave him a look, as I touched my gun, which speedily sent him out of my sight. Resuming our climbing, we reached the top of the cliffs after several hours' hard work, and were rewarded by a magnificent. view of the south end of the lake, lying like a great panorama two thousand feet beneath us. Two hours' marching over a deserted bushland brought us to the village of Setche, where we encamped. I sent a small present to the chief, according to custom, but it was returned with the observation that I was probably not aware he was a great chief, and could not accept such a paltry present from the great white man. I represented that I was ashamed to send so small a present, but I had travelled far and my goods were dwindling fast away. In reply, I was informed that the times were hard and the harvest bad, and he was extremely sorry to say that, in consequence, there was no food in the village for the white man's caravan. Thereupon the porters raised a howl of dismay as they thought of their empty stomachs, and bad names began to circulate. Rather alarmed, I took the question of the present once more into consideration; I found that, after all, I could gladden the heart of the chief with a nice cloth, which proved an Open Sesame" to the granaries of Setche. Two more hard marches brought us to the Arab settlement of Iendwe, situated near the mouth of the river Lofu. It lies in a deep depression of the plateau, forming a broad, densely populated plain on the bank of the river. We entered this important place with all the pomp and circumstance attainable in a caravan. A new English flag replaced the battered Union Jack which had led us from Dar-es-Salaam. The men donned their best, while in front I myself marched, surrounded by a brilliantly dressed body-guard of headmen, each carrying a spear in his hand and a gun slung on his back. I presented a considerable contrast in my free and easy suit of tweeds and only a stick in my hand. The caravan band with its native drums, clarionetlike zomiri, and antelope's horns, made an appropriate amount of noise as an accompaniment to the recitative and chorus of the porters. Crowds of astonished natives lined the path, and at our camping ground there stood a group of Arabs in snow-white shirts and ponderous turbans, ready to welcome me with their "Salaams" and "Yambos." They were dying with curiosity to know where I had come from, and what my objects were. As the tents were being pitched I told them the story of my wanderings, and many were the looks of astonishment and wonder with which it was greeted. Such a march they had never heard of. Countries had been traversed which no Arab would have dared to approach. And then there had been no deaths, no desertions, no stealings, and, strangest of all, I had walked every step of the way, and had neither ridden donkeys nor been carried by my men. I was looked upon as a perfect prodigy, and was universally voted a "Mzungu hodari sana" (a very strong and lucky white man). When I next told them that I intended to go along the west side of the lake a chorus of disapproval met the scheme. It was not to be thought of. No one ever attempted it. One declared the mountains were impassable, and drew dark pictures of the danger of try ing to cross them. A second described the fierceness and the ungovernable savagery of the natives. A third declared there was no food, and that we would all be starved. Not even the natives dare go such a road! Though rather taken aback by these ominous assurances I was not convinced. "See," said I, "these good men of mine. With them I have scaled great and dangerous mountains. I have passed unhurt through tribes that you yourselves say would fight you, if you went among them. We have together crossed countries hitherto unknown. And yet there they all stand, without a single break in their | ranks. Shall I, then, be afraid of this new work? No, I am determined not to be baulked! If the mountains be difficult I shall take light and easy loads. If there is little food to be got I shall take few men with me. And if the natives are dangerous I shall make them my friends, and show them that the white man comes with a different purpose. than to make slaves and to steal their food. This interview shaped my plans at once. Iendwe was a populous place with unlimited supplies of food. I therefore determined to leave all my men, except thirty, under the charge of Chumah; and then, taking only absolute necessaries, to push on by forced marches to the Lukuga. The prospect of a difficult road and adventurous march quite animated me, and made me commence with eagerness the needful preparations. So, on the following morning the men were collected by beat of drum, and my intention was declared. It was necessary to build a house for our goods, and that was at once commenced. The whole caravan, headed by the drummer and piper, set off for the wood to cut poles and bark ropes. At mid-day they returned loaded, but singing lustily all the time. The men entered into my schemes most heartily, and as it was necessary to hurry off before the worst of the rainy season came, they worked as if it was a matter of life or death. In two days the largest house in that part of the world was erected by the hundred and fifty men, and we were ready to start. The loads were speedily prepared, and it only remained that the personnel of the travelling party should be determined. As this trip was to be manifestly a dangerous one, I determined to take only volunteers. The men were called up and the question was asked, Who would go? On the one side were hardships and manifold perils: on the other idleness and ease. The latter alternative was tempting to dispositions like the Waswahili. Yet no time was lost. First one and then another and another cheerfully offered himself for the enterprise, till, from the best of the caravan, I was able to select the required number-thirty. The Arabs had been extremely hospitable and had loaded us with presents. And now, on the morning of our departure, they arrived. in a body to conduct us a part of the way, bringing us rice, fish, and fowls to carry with us. (To be continued.) NOTE.

Even so, and with a multitude of pieces of 16 oz. glass-so called in the trade, but really never more than 14 oz.-sticking in his wounds, with the putty still upon it, Dicky Touchwood came to himself; and lost it, ere ever he had time to scratch it; which is the first of all bodily instincts. For over him leant the very loveliest creature, ever | seen out of a dream, or in it. Deep compassion, sweet anxiety, and an inborn dread of the Coroner, or the Doctor who precedes him, filled the beautiful eyes of Rose Arthur. The youth looked up, and had a very clear idea of having flown up to what our poets call "the blue." Hush!" the maiden whispered, as his lips began to move; "keep your head upon the flower-pot, and try to think of nothing. Never mind about all the things you have broken. You did not mean to do it, and it can't be helped now. The only thing you have to do is to keep as still as possible. Papa is gone to meet Dr. Perperaps, and he may be expected at any moment. You are to go to sleep, until he comes.” The heavily wounded youth, instead of obeying orders, gazed the more. To look at her was poetry, and to listen to her was music. But she turned away, and left him nothing for his eyes. | Richard Touchwood, Esquire, jumped up, when he heard himself called "a smallish boy." Or rather, he tried to jump up, but his swathings stopped him, and then a very jagged barb of pain; and then a light hand replanted him among the grains, and upon the pot. "You are too bad," she said, "you want to go everywhere where you have no business. But oh, I am so sorry for your pain, poor boy! If you would only cry a little, it would do you so much good." "Cry!" exclaimed Dicky, in a high tone of disdain, yet not wholly out of concert with the course suggested; "have you never even heard that I am a Caius-College man, the place where the very best physicians come from?” No, I never heard of that. I have heard of hospitals, and the wards that belong to them; but never of keys colleges. Since you are in training for the medical profession, you ought to try more than you do, to enter into your own position. It is a strict necessity for you to lie still; but instead of doing that- oh here comes Dr. Perperaps, crossing our bridge very nicely indeed! And he has brought his daughter Spotty with him. He never goes anywhere without Miss Spotty. Now you will be in better hands than mine. Good-bye." "It must have been an angel.
