The negroes and slaves of New Spain form a very inconsiderable part of the population; of the negroes, there are only about 6000, and many of them are free; of slaves, about 10,000, who are negroes, and the Indians who are taken on the frontiers by the missionariesʼ troops; these slaves are to be found only at Vera Cruz, Acapulco, and on the coasts; employed in the ports, the culture of sugar, indigo, &c. being almost entirely the work of the free people. The slaves are, with the exception of the Indian prisoners, treated mildly, and gain their freedom by amassing, if they are of an active turn, a small sum which they give to their owner, who is forced to emancipate them; this sum is from sixty to eighty pounds. The mestizoes, mulattoes, zambos, and people of mixed blood, amount to about 2,400,000. The mestizoes, are represented as a mild and well conducted people, differing in hardly any thing from the whites. The mulattoes have that revengeful disposition, versatility of conduct and voluble tongue, which they possess in all other quarters of the world. The aboriginal race form a large section of the Mexican population; their number, as before stated, amounts to about three millions; they inhabit, chiefly the central and southern part of New Spain, and in these regions they are mostly to be found concentrated in towns and villages. Towards the north the Indians are, with the exception of a few, who have been converted by the missionaries, wandering tribes who subsist by the chace, and by the plunder of the Spanish settlers. The military stations are in constant activity against these people, they frequently capture numbers, who are sent to Mexico, as slaves. For the history of the migration of the Mexican race we must refer to the description of the province of Mexico, under which head will be found some interesting details of the principal events which have taken place in respect to these people, up to the period at which they were subjugated by the Spaniards.
