This pious divine wrote a treatise upon the subject, which he dedicated to the then archbishop of Canterbury.

He gave it to the world, at the time mentioned, under the title of "_The Negroes' and Indians' Advocate._" In this treatise he lays open the situation of these oppressed people, of whose sufferings he had been an eye-witness in the island of Barbados.
He calls forth the pity of the reader in an affecting manner, and exposes with a nervous eloquence the brutal sentiments and conduct of their oppressors.

This seems to have been the first work undertaken in England expressly in favour of the cause.
The next person, whom I shall mention, is Richard Baxter, the celebrated divine among the nonconformists.

In his _Christian Directory_, published about the same time as _The Negroes' and Indians' Advocate_, he gives advice to those masters in foreign plantations, who have negroes and other slaves.

In this he protests loudly against this trade.
