And here
it may be proper to observe, that it is by no means necessary that all
these should have been themselves actors in the production of this great
event. Persons have contributed towards it in different ways:--Some have
written expressly on the subject, who have had no opportunity of promoting
it by personal exertions. Others have only mentioned it incidentally in
their writings. Others, in an elevated rank and station, have cried out
publicly concerning it, whose sayings have been recorded. All these,
however, may be considered as necessary forerunners in their day. For all
of them have brought the subject more or less into notice. They have more
or less enlightened the mind upon it. They have more or less impressed it.
And therefore each may be said to have had his share in diffusing and
keeping up a certain portion of knowledge, and feeling concerning it, which
has been eminently useful in the promotion of the cause.

It is rather remarkable, that the first forerunners and coadjutors should
have been men in power.

So early as in the year 1503 a few slaves had been sent from the Portuguese
settlements in Africa into the Spanish colonies in America. In 1511,
Ferdinand the Fifth, king of Spain, permitted them to be carried in greater
numbers. Ferdinand, however, must have been ignorant in these early times
of the piratical manner in which the Portuguese had procured them. He could
have known nothing of their treatment when in bondage, nor could he have
viewed the few uncertain adventurous transportations of them into his
dominions in the western world, in the light of a regular trade. After his
death, however, a proposal was made by Bartholomew de las Casas, the bishop
of Chiapa, to Cardinal Ximenes, who held the reins of the government of
Spain till Charles the Fifth came to the throne, for the establishment of a
regular system of commerce in the persons of the native Africans. The
object of Bartholomew de las Casas was undoubtedly to save the American
Indians, whose cruel treatment and almost extirpation he had witnessed
during his residence among them, and in whose behalf he had undertaken a
voyage to the court of Spain. It is difficult to reconcile this proposal
with the humane and charitable spirit of the bishop of Chiapa. But it is
probable he believed that a code of laws would soon be established in
favour both of Africans and of the natives in the Spanish settlements, and
that he flattered himself that,
