The emirs accompanied Kamal ed Din to Omdurman in triumph, where he also gave proof of the excellence of his powder in the presence of the Khalifa. Abdullah was wild with joy, and presented the inventor with 200 dollars and a concubine. The Indian now returned to Khartum with profuse promises that he would supply several hundredweight of the new powder in the course of a month.

But soon people began to talk of him as being a cheat and a deceiver; a month passed and the powder was not delivered; the head of the beit el mal became anxious, and reported the matter to the Khalifa, who at once sent his brother Yakub and Wad Adlan to make inquiries on the spot; they went, and it was very evident that the Indian had been duping them all the time. He was brought before the Khalifa, and, strange to say, was not punished. Abdullah merely remarked that he was a poor foreigner, and, of course, had to do his best to make a living. It is a curious thing that Abdullah has a much greater insight into the ways of foreigners than most natives.

A certain mukuddum, however, of the Jaalin tribe did not get off so easily. In the days of the Government he had practised an extensive fraud in Khartum, and also in Sennar as an alchemist, and now he came forward to offer his services for the manufacture of lead. At first he had been occupied in making gold, but now to the Khalifa lead was even more precious than gold, and the want of it was causing him grave apprehension.

The mukuddum's offer was accepted, he received presents from the beit el mal, where he was given a special place in which to carry on his work, and numbers of slaves were placed at his disposal; he was given all the money he required to purchase various things in connection with the manufacture, and which he asserted were absolutely essential. Four slaves were told off to keep up an enormous furnace, whilst the mukuddum, his head and shoulders swathed in a great mantle, beat the ground madly with a long whip in order to call the Jinns to his assistance. His curious antics greatly astonished the people, and he soon became the principal topic of conversation in Omdurman. After fourteen days an enormous lump of lead was drawn out from the furnace, and his reputation was made.

The Sudanese are great believers in alchemy; and it was thought that the preparation of one of the ingredients required the greatest secrecy. The mukuddum, therefore, worked fully on the superstitious nature of the people, and a thick cloud of foul-smelling smoke was seen continually issuing from his mysterious and dark laboratory. The lead was at once sent to the Khalifa, who appeared thoroughly convinced of the miraculous power of the maker, and indeed had the piece brought into the mosque to expose it publicly. The sycophants of course told him that this was an undeniable miracle on the part of the Mahdi, who had been the means of supplying the precious metal to his successor through this mukuddum.

The manufacturer was now in high favour, the Khalifa pressed him to continue the work, and supplied him liberally with money and female slaves. One of the Europeans had urged him to desist, telling him that it was quite impossible to manufacture lead; but the mukuddum answered him three times in the most solemn manner: "Do you think that you know the knowledge of God?" and then went on with his work. From time to time he continued to send pieces of lead to the Khalifa, but his supply only lasted a few months; the more sensible people began to talk, they urged that if he could make one piece of lead, he could also make several hundred-weight. The voice of the detractors grew stronger, the Khalifa's suspicions were aroused, and the mukuddum was summoned into his presence. He asked him in the most kind manner if it was a fact that he really knew how to make lead, or if he was only attempting to deceive; if the latter—and he confessed to it—then he might receive forgiveness.

But this kindly warning was entirely without effect; the mukuddum boldly answered that he did know how to make lead, and moreover abused his detractors, calling them enemies of Mahdiism, who hated the Khalifa, and did not wish him to be possessor of the precious metal. He added that, if given sufficient time, he would prove his enemies to be liars. The Khalifa permitted him to continue his work a little longer; but the results were still the same, and he was again summoned before Abdullah, who now threatened to cut off his hand and foot unless he confessed that he had been practising a fraud; but still the mukuddum persisted in his denial, and the Khalifa ordered three chains to be forged for his feet, and had him sent back to his laboratory under a strong escort; he was to be permitted to work for three days longer.

He now redoubled his antics, making the dust whirl in clouds about him, and crying on the spirits to aid him. He put a few pounds of substance into the fire—all that was left of his lead-scrapings—but this time the spirits left him in the lurch. Bathed in perspiration, he anxiously raked about the coals; but there was no lead to be seen. He begged and prayed for more time, which was granted. But at length one of his slaves let out the secret; he said that the mukuddum used to purchase in the market the lead bullets which had been dug out of Khartum, he filed them into thin shavings, mixed them with some concoction, and threw them into the furnace; the melted lead was then drawn off and allowed to cool. On the last occasion he had failed, and now his fraud was fully exposed; the Khalifa ordered his hand and foot to be cut off, "not," he said, "so much for the fraud, as for the continual denials." The operation was carried out, but the mukuddum died eight days afterwards of tetanus.

The failures of this man and of the Indian to manufacture powder and lead did not deter others from continuing their experiments, and amongst the latter was a Greek named Yusef Pertekachi, who continued working on with the most dogged determination. He had tried every plan to gain a livelihood; but whatever he put his hand to, it seemed to fail, and he was soon deeply involved in debt. In his desperate position he determined to study the manufacture of gunpowder. For a whole year he continued his experiments, and in his case the truth of the proverb, "Necessity is the mother of invention," was fully exemplified; he succeeded in making fairly good powder.

The experiences of the Indian and the mukuddum pointed to extreme caution; he did not, therefore, tell Adlan, who he thought would not believe him, but after his death he applied to Yakub.
