The discoverer has at last been discovered, and The discoverer has at last been discovered, and the'inquisiti-ve mind of ouir race once more finds itsell on the tr~ack of the grcat problem which has occupi'ed geographers-and many besides geogra- phers-since- the beginming of history. There are not only now;, but letters from Dr. LvwIo- STO,xz, still at their date able, ardent, hope- ful, and persevering, The great traveller has learnt to laugh at despair, and sees in the prospect of utter destitution in the midst of -savage and barbarous tribes only a new and ridiculous phase of his singular careers It appears to have beea a matter of comparative indifference to Dr. LiixVNG- STNEoN whether he bad to distribute the gifts of civiliz&tion to tribes fuly able to appreciate them, or to supplicate aid and hospitality from chiefs who cannot so well appreciater his -errand. Re&iced to a mere " rackle of bones,'V foot- sore, plundered by everyboay of etverything, and having no chpice but to trust those who could not be trusted, he was still, last February, rejoicing in the hope df deacribing oue day to the 'civi- lized world the great watershed of gonthera Africa. b;uch more he has to describe,- but, pursued by the old fate of African explorers, he has found hiinself driven back at the most interesting point of his dis6overiesz Sik han- dred- miles of the mysterious watershed he had traversed, but so far hls had to rulinquish the remaining hundred, the most interesting of the whole, whence, from a source old- as his- tory, flow four sareams, soon becoming great 'rivers-two ruuing northward towards Egypt, two southward into] inner. Ethiopia. Dr. IvLNesrsas was longing for home, bat all his life this nsio- had been before him; he had been assured of its-cer- taiRty, and it had becqme the re4 home of his hopes and affctions. l, Plundered by carera, cheated by servants 'and mercantile ageats, at downright war vrith slave-dealing Sultans, aus with his supplies equally dissipated on the journey or at the depOt aud never reaching him, he was clinging to the great hope of his life, and still believing it within reach. We are per- mitted to hope that the man who has survived such difficulties, adld who in a charmed rqgion himself bears a qharmad life,will one dy return and supply the long gap in his story.; Yet how he can do it evd&i then is hard to be conceived. They who live ut home know how much they are dependent on eommon comforts for even such slight worlk as cor- respondenue or a journal The work wlirih half the world now expects, and will certairly read when it appears, has to be sabstantiaily composed in a, region where it is no slight achievement of endur-' ance and ssgacity to retain one's life and sen,ew and to adrance hIf a dozen milos a day. ;w -But we h .ae yet to learn mametng else a's won- derful- a apnything even in Dr. Irv=asnosK8 own adventures and fo tunes."' If there be one thing we should have thought beyond the power of san soii t i ndividual, it would bo to fund a given man u the interior of Africa looked for simply because notheard of. For years have people at home been indulging in the wildest guesses as to the posi- tion and the possible plans and intentions of Dr. LIVn;r.GSTONF, and .?r. SrA-TLEYseems to have struck on his trail at once with the instinct of a REed Indian. Geographic4l Societies have met and met, aud talked and talked, and an expedition has been sent out carefully selected in men and material. By far the most probable account of the long silence was that the great traveller had met with the too commoa fate of travellers ; indeed, it lhad been positively and circumstantially related. An cuterprising newspaper proprietor picks his niau, and asks him to go and look fbr LIviNesTonv. Fortunately, the man thus invited is equal to tha task. He sets off and does it while others zre idly talking or slowly planLning. Africa is a very wide target, but Mr. STANLEY hit the bull's-eye at once. One knew well eniougih that it was a country to lose oneself in,-indecd, Dr. LivnGsroNE is one moro instance of that,-but not that it was a country in which yoa could look for a man, find him in the crowd of a market-place, aud accost him with " I presume it is Dr. LivnifGSTONE I am speak- " ing to 22' With this iadividual energy and deci- sive success the sudden and early collapse of the i Rxpedition!b presents a ludicrous contrast. Wehave no wiBh to be harcl on 31r. Nj&Nv and his associates, but the comparison of his lett&r with that of Dr, LivimrTsroyz, placed on Saturday in the ad- joining column, cannot fail to suggest soene re- flections. The "'Expedition" started, it seems, all well from Zanzibar, after the official rela- tions of the members had been carefully and distinctly defined, wit'h due provision for emergen- cies. Perhaps the men were ill assorted, but they knew it, arnd took it all into account. In crossing the channdl between Zan2ibar and the main- land they got a rouga tossing and ducking, and on landing the next day found they had been anticipated, and that Dr. Liivrc- STONE had been discovered. Ordinary readers, whose spirits have not been brokea by a night at sea in an open boat, and whose tempers have not been ruffled by a few hours of ill-sorted companion- ship, wrill perhaps think that the " Expedition" was to ber congratulated, inasmuch as it had got the scent at once, and had only to follow it up. The "'Expedition" must have understood, we should think, and even hoped as a condition of success, that it would one day have certain and reliable news of Dr. Liviasro.E, and that the news would be valuable, because leading to the object itself. The search was stiU open, with the great advantage of being easy and dist-acted by no doubt. We cannot conceive why it did not proceed, just as it was, and under the original name-" the Livingstone " Searchald Relief Expeflition." It certainly had got to find LIVINGsTOXE aud help him; nay, for aught we knoyr, he may have perished long before this for want of the very help the " Expedition " was sent to give if it could find him. These gentlemen' however, assumed at once that there was no longer a search to be made. Dr. LtvrxosToNE had been found. The question now was whether he was to be re- lieved,and whether theywho had pledged themselves to look for him and relieve him were bound by that pledga to relieve him nowr they knew where he was. We really slhotlid have thought there was no doubt about it. However, they began to de- bate, to back out, to make objections, and one after another to withdraw from the " Expedition,'" or, as it is ingeniously put, to decline the simple conduct of supplies. Mr. Nvw had wiith some difficulty seen his way to a " search," but thought " relief " hardly sufficient to call for the sacrifice of his ordinary employment, or of a meditated return to this country. If the Decron returns home safe we shall probably hear no more of the " Ex1 pedition.`'> If not, it will have to stand some unpleasant criticism. iv _" I 'I Eut even if we never, see Dr. LivuiosToxv again, I one great illusion is dispelled, and the long mystery I that hung over Africa is no more. A man can tralveiLe the Continent in many directions, make his way under difficulties, acid survive to be found, and even to tell his tale, even if it only be the old Afri- can tale of roguery and barbarism. Could a solitary -mn traverse any other quarter of the world and live to tell his tale' Certainly he could not make his way without mone-y or friends. If we at to judge from the present rate of pro- gress, the next generation, or at least the next after, will see a railway right across the great waterihed of Southern Africa, joining the two oceans. The torrid zone is not uninha6itable, nor are its. people inhospitable. The climate is bear- able, the country fertile, the native races quite as amenable to proper treatment as native races usually are. Dr. LixVNGsTo0rE has spent not far from half his life there, and evidently thiinks that if we can get the Portuguese and the haf-caste Moalems to leave the people alone they may be made a goodc deal of-rat least, made good frie.ads. Should that time come, the name of LivL-NGsToNx will have a place among earth's founders and benefactors. Fifty years ago it was thought as impossible to open up Africa as to break thriotigh the wall of China or. make a landing in Japan. These andtwenty other impossibilities have since been tried and orvrcome. We shall one day enter the heart of Africa, And wonder that it should ever be amaystery. It may even prove a nearer| and more useful Ihdia, with equal industrial re- sources and habitable regions. That we can even call this possible wet owe to Dr. LIVIwOSTONE.
