Wallis, in his _System of the Laws of Scotland_, maintains, that
"neither men nor governments have a right to sell those of their own
species. Men and their liberty are neither purchaseable nor saleable."
And, after arguing the case, he says, "This is the law of nature, which
is obligatory on all men, at all times, and in all places.--Would not
any of us, who should be snatched by pirates from his native land, think
himself cruelly abused, and at all times entitled to be free? Have not
these unfortunate Africans, who meet with the same cruel fate, the same
right? Are they not men as well as we? And have they not the same
sensibility? Let us not, therefore, defend or support an usage, which is
contrary to all the laws of humanity."

In the year 1750, the reverend Griffith Hughes, rector of St. Lucy, in
Barbados, published his Natural History of that island. He took an
opportunity, in the course of it, of laying open to the world the
miserable situation of the poor Africans, and the waste of them by hard
labour and other cruel means, and he had the generosity to vindicate
their capacities from the charge, which they who held them in bondage
brought against them, as a justification of their own wickedness in
continuing to deprive them of the rights of men.

Edmund Burke, in his account of the European settlements, (for this work
is usually attributed to him,) complains "that the Negroes in our
colonies endure a slavery more complete, and attended with far worse
circumstances, than what any people in their condition suffer, in any
other part of the world, or have suffered in any other period of time.
Proofs of this are not wanting. The prodigious waste, which we
experience in this unhappy part of our species, is a full and melancholy
evidence of this truth." And he goes on to advise the planters, for the
sake of their own interest, to behave like good men, good masters, and
good Christians, and to impose less labour upon their slaves, and to
give them recreation on some of the grand festivals, and to instruct
them in religion, as certain preventives of their decrease.

An anonymous author of a pamphlet, entitled, _An Essay in Vindication of
the Continental Colonies of America_, seems to
