The sage Eben Bonabben shook his dry head at the words. “Here is an end to philosophy,” thought he. “The prince has discovered he has a heart!” He now kept anxious watch upon his pupil, and saw that the latent tenderness of his nature was in activity, and only wanted an object. He wandered about the gardens of the Generalife in an intoxication of feelings of which he knew not the cause. Sometimes he would sit plunged in a delicious reverie; then he would seize his lute and draw from it the most touching notes, and then throw it aside, and break forth into sighs and ejaculations. By degrees this loving disposition began to extend to inanimate objects; he had his favorite flowers, which he cherished with tender assiduity; then he became attached to various trees, and there was one in particular, of a graceful form and drooping foliage, on which he lavished his amorous devotion, carving his name on its bark, hanging garlands on its branches, and singing couplets in its praise, to the accompaniment of his lute. Eben Bonabben was alarmed at this excited state of his pupil. He saw him on the very brink of forbidden knowledge--the least hint might reveal to him the fatal secret. Trembling for the safety of the prince and the security of his own head, he hastened to draw him from the seductions of the garden, and shut him up in the highest tower of the Generalife. It contained beautiful apartments, and commanded an almost boundless prospect, but was elevated far above that atmosphere of sweets and those witching bowers so dangerous to the feelings of the too susceptible Ahmed. What was to be done, however, to reconcile him to this restraint and to beguile the tedious hours? He had exhausted almost all kinds of agreeable knowledge; and algebra was not to be mentioned. Fortunately Eben Bonabben had been instructed, when in Egypt, in the language of birds by a Jewish Rabbin, who had received it in lineal transmission from Solomon the Wise, who had been taught it by the queen of Sheba. At the very mention of such a study, the eyes of the prince sparkled with animation, and he applied himself to it with such avidity, that he soon became as great an adept as his master. The tower of the Generalife was no longer a solitude; he had companions at hand with whom he could converse. The first acquaintance he formed was with a hawk, who built his nest in a crevice of the lofty battlements, whence he soared far and wide in quest of prey. The prince, however, found little to like or esteem in him. He was a mere pirate of the air, swaggering and boastful, whose talk was all about rapine and carnage, and desperate exploits.
