"I thought that no plant was ever to be found on those mountain tops covered with perpetual snow and frost?"
"There grows none, but that of which I have immediate need; I am going in quest of it, and will show it thee on my return."
"It is well," said Selim, and they separated.
Hussein Muley retreated with rapid strides.
Selim carefully placed in a small box the powder which he was to take fasting, during one year, three months, a week, and a day, and he began from the very next day to administer to himself this drug, which happily he did not find to be very nauseous to the taste.
Meanwhile the Tunisian set out from Aldgezaire with his wife, his children, and several chests, containing no doubt his books, and the papers necessary for his studies; but Selim never saw him more. He awaited his return, three, five, ten years, and, as he judged that ten years should suffice to go to Asia, and scale the highest mountain there, he began to think that the yellow, thin, and learned Tunisian was either dead, or else had taken advantage of his credulity and ignorance.
Whilst these thoughts occupied his mind, an epidemic broke out in Aldgezaire; Selim was attacked by it.
He therefore begged the wise mufti, who was still alive, to come and visit him; and then with that burst of confidence which seizes men in the hour of danger, he opened his heart to him, and related how he had given two caskets full of gold to Hussein Muley, in the hope of prolonging the existence of mankind for many centuries.
The wise mufti stroked his venerable beard and exclaimed:
"Selim, Selim, thou hast been played upon by a swindler, to whom thou hast imprudently confided thy generous thoughts. This proves the truth of what I one day said to thee, 'With the best intentions we may commit the most foolish actions.'"
