ing found some who had approved
his tracts, and, to whom, on that account, he wished to write, and
sending his tracts to others, to whom he thought it proper to introduce
them by letter, he found himself engaged in a correspondence which much
engrossed his time, but which proved of great importance in procuring
many advocates for his cause.

In the year 1762, when he had obtained a still greater store of
information, he published a larger work. This, however, he entitle _A
short Account of that part of Africa inhabited by the Negroes_ In 1767
he published _A Caution and Warning to Great Britain and her colonies on
the calamitous state of the enslaved Negroes in the British Dominions_;
and soon after this appeared, _An Historical Account of Guinea, its
Situation, Produce, and the general Disposition of its Inhabitants: with
an Inquiry into the Rise and Progress of the Slave Trade, its Nature,
and Calamitous Effects._ This pamphlet contained a clear and distinct
development of the subject, from the best authorities. It contained
also, the sentiments of many enlightened upon it; and it became
instrumental beyond any other book ever before published, in
disseminating a proper knowledge and detestation of this trade.

Anthony Benezet may be considered as one of the most zealous, vigilant,
and active advocates which the cause of the oppressed Africans ever had.
He seemed to have been born and to have lived for the promotion of it
and therefore he never omitted any the least opportunity of serving it.
If a person called upon him who was going a journey his first thoughts
usually were how he could make him an instrument in its favour; he
either gave him tracts to distribute or he sent letters by him, or he
gave him some commission on the subject; so that he was the means of
employing several persons at the same time, in various parts of America;
in advancing the work he had undertaken.

In the same manner he availed himself of every other circumstance, as
far as he could, to the same end. When he heard that Mr. Granville Sharp
had obtained; in the year 1772, the noble verdict in the cause of
Somerset the slave, he opened a correspondence with him which he kept
up, that there might be an union of action between them for the future,
as far as it could be effected, and that they might each give
encouragement to the other to proceed.

He opened also a correspondence with George Whitfield and John Wesley
that these might assist
