Occasionally, however, but very rarely, they may be found to join agricultural operations with the Arabs.
The Moors may be divided into the four following classes:--1st.

The tribes descended from _Arab_ families.2nd.Those of _Berrebber_ descent.3rd.The _Bukharie._ 4th.

The _Andalusie._ The _Arab_ families are the brethren of the conquerors of the country, and they form the largest portion of the population of the southern towns, especially of those, which border on Arab districts.
The _Berrebber_ families are in like manner more or less numerous in the towns, according to the proximity of the latter to the Berrebber districts.
The _Bukharie,_ or black tribe, are the descendants of the negroes, brought by the emperor Mulai Ismael, from Soudan.

They have been endowed with gifts of land, and otherwise encouraged by the subsequent emperors, and the tribe, although inconsiderable in point of numbers, has been raised to importance in the state, by the circumstance of its forming the standing army of the emperor, and of its being employed invariably as the instruments of government.

Their chief residence is in the city of Mequinez, about the emperor's person.
