A VILLAGE ON THE GUINEA COAST.

"Quite right," said the Doctor, as Frank paused. "It was in that first exploration he was treacherously attacked and robbed by his guides in the desert, who left him for dead on the sands, with a broken arm. In 1864 he again travelled in Morocco, and a year later he started from Tripoli, in the disguise of an Arab, and went to Lagos, on the Gulf of Guinea, by way of Moorzook and other cities in that part of Africa. He passed Lake Tchad, and continued to the Niger, which he partially explored, together with the river Benoowe, which has already been mentioned. His name is familiar to many people in America, as he visited the United States in 1875, and lectured there on his travels.

"He tells some interesting stories of his adventures," the Doctor continued, "while travelling in disguise. He had managed to make the Grand Shereef of Morocco his friend, and he secured letters that caused him to be received with distinguished honors in most of the towns and cities that he visited. As he spoke Arabic fluently, and knew all the Moslem prayers by heart, his religious faith was not often called in question. Occasionally, however, he was open to suspicion, and as he was among the most fanatical Moslems his life was in great danger.

"At Tidikelt he was received very kindly by the prince to whom he had several letters of introduction. One day a Touareg sheik came to him and said,

"'I am a prince of the Touaregs; I have been in Paris, and know the whole country of France, and I know the Sultan of the Christians. I know you, and have seen you; you are a Christian, and a Frenchman or an Englishman.'

"Rohlfs assured the man that he was neither French nor English; but the latter was so certain about it that he went to the Prince of Tidikelt and stated his suspicions that Rohlfs was a French spy, who had come to see what the land contained. Fortunately, the prince did not believe him; and when Rohlfs spoke about the matter the prince replied that he was certain he would not have been able to get a letter of recommendation unless he had been a Moslem. He added, 'If a Christian should come into our land provided with letters from the Sultans of Stamboul and Morocco, I should at once hand him over to the people, for we don't want any Christians here.'

"The answer was not at all encouraging, as it showed the great danger he was in. He would gladly have left at once, but could not do so, as the mere fact of his trying to escape would only strengthen the suspicion against him. So he put on a brave front, and by the practice of his medical skill and careful attendance to the religious ceremonies he managed, in the course of a month or so, to get on friendly terms with everybody once more. Then he continued his journey, and in due time reached the regions where Christians were safe.
