These explanations, so far from inducing us to give up our ideas of mercy, made us more persistent. It is, perhaps, both imprudent and indiscreet to turn a poisoner loose on society, even if that society be African, and if it were merely a question of hanging or beheading, we should probably allow justice to take its course. But the sufferings the poor wretch endures and those which are in store for him, the very horror of his punishment, all render his crime less odious. In the victim we forget the criminal.

Armed with our knives we were again preparing to cut the prisoner's bonds, without condescending to pay any attention to the protests or remonstrances of the Al-Waj, when our interpreter Ali called our attention to the sky.

"Well," said Delange, to him. "What part does the sky play in this matter? Are you afraid that the sun will resent our depriving him of his victim? He never asked for him—no offer even was made to him."

"That is not what I meant," replied our guide. "I pointed to the sky, because at this moment it is covered with clouds. A storm will soon burst over us, the rain will fall in torrents, and as the prisoner will be saved by natural causes it is of no use our making enemies of all this tribe."

"Granted," said Delange. "The sun will be interrupted in his work of destruction. The rain will refresh this poor wretch, and will wash his wounds. I admit all that, but the luminary will soon reappear brighter and more burning than ever."

"The punishment will soon be at an end," our guide hastened to explain, "in accordance with the customs of the tribes of these regions. They have been suffering for some time past from a terrible drought, and the rains, which usually commence at the end of February, are this year a fortnight late. You have already had the Dinkas, who stand in great need of water for their flocks and herds, coming to you, and offering you ivory and slaves if you would prevail upon the rain to fell. The Al-Waj suffer quite as much as their neighbours. Superstitious, as, indeed, we all are in Africa, instead of recognizing that the rainy season will eventually commence in due course of nature, they will think that the sun does not desire the victim offered up to him, and that in order to protect and save him that luminary will withdraw his rays. Not only in that case will they hasten to cut the prisoner's bonds, but they will raise him to the dignity of a sorcerer, and, attributing to him the power of making the sun stand still and of causing the rain to fall at his will and pleasure, they will pay him the greatest respect."

The Arab was right. The rainy season was fairly setting in, and very soon a tremendous storm burst forth. Then, as he had said, the natives rushed towards their prisoner, cut his bonds, and prostrated themselves before him.

Did the slave, thus miraculously saved, really believe that he was protected by the sun? Did he seriously regard himself as a sorcerer? We did not seek to enquire, but we saw him, as soon as he was released, look proudly round him, and, followed by his former persecutors, now become his admirers, wend his way towards the village, where he would be looked upon as a demi-god, be worshipped by all, and be held capable of causing rain or sunshine as he pleased.

Perhaps, too, he counted upon being able to resume his particular trade as a poisoner, but there would no longer be any one to say him nay—in his capacity as sorcerer and demi-god, his poisoning would be carried out under official sanction.

10th March.—We are progressing very rapidly, for, thanks to extra rations and a few presents, we are getting double stages out of our escort. We now rest from 10 a.m. to 4 p.m., continuing on the road from the latter hour until nine or ten o'clock at night in the clear, bright moonlight. We start, as usual, for our first stage at 5 a.m., and have now reached a kind of neutral ground, about three hundred square miles in extent, in which are situated, some five or six leagues from each other, the celebrated seribas, or depôts, of the Khartoum merchants. Owing to the letters of introduction presented to us at that town, we have been received most hospitably at all these depôts, thatched and roomy huts being placed at our disposal, as well as provisions for both ourselves and the caravan generally.
