men and by the persistent inculcation of the virtues of charity and forgiveness, it gradually weakened, and ultimately abrogated, the law of blood-revenge, which the Bedouin had been accustomed to consider his most cherished privilege; a right whose violation, according to popular opinion, involved the honor of his tribe and the assertion of his manhood. It liberated property from the arbitrary impositions of a horde of petty chieftains, who levied excessive tribute to the infinite detriment of commerce, and imposed a single tax--the tenth of the increase--understood and acquiesced in by all. It punished mercilessly the abuses which arose from the unprincipled exactions of usury, and, by the enforcement of laws of unexampled rigor, guaranteed the safety of travellers in regions where successful robbery had been a mark of personal distinction, and where the outrage of private rights was still the unquestioned prerogative of every inhabitant whose arm was more powerful than that of his neighbor. Attaching the highest importance to habitual cleanliness, it commended its daily observance, and, to avoid a plausible excuse for neglect, it suggested the use of sand, as symbolical of water, in localities where the latter could not be obtained.

The unseemly contests of sacerdotal ambition, the senseless privations of asceticism, the bloody and turbulent spirit of monastic bigotry, were, by the prudence and foresight of its founder, excluded from its system. Imposing a moderate contribution upon all those in its dominions who declined to abjure the faith of their ancestors, it, upon the other hand, refused to the ministers of other religions, its vassals, the privilege of taxing the members of their congregations without their consent. It impressed upon youth, of whatever rank or station, the obligations of polite and courteous behavior and the unremitting exercise of filial piety. It accorded to every seeker after truth the inestimable privilege of private interpretation and individual opinion,--an inherent right of man refused by Christianity until the time of Luther, who, on account of his advocacy of this
