Ball spent the day in botanising over the hills near the town, and was well satisfied with the result. The rarest plant found was, perhaps, a curious and very distinct fumitory (_Fumaria africana_ of Lamarck), which he had gathered nearly at the same spot twenty years before. The red-flowered Polygala of Beni Hosmar (_P. Webbiana_ of Cosson) was seen in a few spots near the town along with _Arabis pubescens_; and that singular plant, the _Drosophyllum_, hitherto seen in Marocco only on the hills west of Tangier, was here found within sight of the Mediterranean, growing along with _Helianthemum umbellatum_ and several other less rare species of the Cistus tribe. During our stay here we had a good opportunity of seeing something of the life of the Marocco Jews, who form a distinct and important element in the population of the empire. Tetuan has long been one of the head-quarters of the Hebrew race. When most of the chief Moorish families took refuge here after their expulsion from Spain—and some are said still to preserve the keys of their own houses in Granada—many Jews, flying from the faggots of the Inquisition, preferred the comparative toleration of Moslem rule, to the oppression and social disabilities that awaited them in Christian Europe. It was more tolerable to submit to occasional injustice and cruelty which was shared by all classes of society around them than to be daily reminded that they formed a class apart—the proper objects of general contempt and aversion. It is true that until late years the Marocco Jew was exposed to some vexatious regulations. He was required to put off his sandals on passing the outside of a mosque, to wear a peculiar dress, and is still confined to a separate quarter in each town. But in ordinary intercourse between man and man the Jews of the coast towns seemed to us to have attained a footing of almost complete equality, due as well to their superior intelligence and commercial instinct, as to the tolerance which affinity of race and creed has developed among the people of Arab stock. In truth, the Moor feels that the Jew is indispensable to him. In despite of his aversion to intercourse with the Christian, trade, in which the Jew serves as intermediary, has become a practical necessity, and it has procured for him foreign luxuries which he is now little inclined to forego.
