The doctor and his companion returned to Kukaka on the 1st of February, 1852. On the 4th of March, Dr Barth again set out on a journey to Begharmi, a considerable distance to the south-east of Lake Chad. His only conveyance was his own horse and a she-camel for his luggage. The next day Ovenveg, who had resolved to explore Lake Chad in a boat, parted from him, and he proceeded on his hazardous expedition alone, his course being to the south-east, along the shores of the lake. He passed several towns in a state of decay. In that of Ngla the palace of the governor was of immense size for Negroland. It had large and towering clay walls, having the appearance of an enormous citadel. He was hospitably treated at the large town of Loggun. Here the river of the same name, which falls into Lake Chad, is from three hundred and fifty to four hundred yards across. About forty or fifty boats of considerable size floated on the stream. He made an excursion on the river, when he excited great admiration by firing at a crocodile, though he did not kill the creature. The sultan formed so high an estimation of the traveller, that he wished him to remain to assist him in fighting his enemies, but the doctor, being anxious to proceed eastward, induced him at length to let him take his departure. On the 16th of March he left Loggun to endeavour to penetrate into regions never before trodden by European foot. He crossed the river in a boat, while his horse and camel swam over. Passing through a dense forest, he observed the footprints of the rhinoceros, an animal unheard of in the western parts of Negroland. It is greatly feared by the inhabitants. Little further in advance he suddenly beheld through the branches of the trees the splendid sheet of a river far larger than that of Loggun. All was silence, the pellucid surface undisturbed by the slightest breeze; no vestige of human or animal life, with the exception of two hippopotami which had been basking in the sun on shore, and now plunged into the water. This was the real Shary, the great river of the Kotoko, which with the river Loggun forms a large basin, giving to this part of Negroland its characteristic feature. After some time a ferry-boat appeared, but the ferrymen declined carrying the party over before they had informed their master. While waiting for them, a large troop of pilgrims on their way to Mecca, mostly from the western parts of Negroland, came up, and the doctor made them a present of needles. The boatmen, returning, declared that the chief of the village would not allow him to pass. He was, however, not to be defeated, and, proceeding along the banks of the river, at length found some ferrymen who did not hesitate to take him across. He was, however, soon again stopped, and, after repeated attempts to push on, was compelled to take up his residence at a place called Bakada.
