By the publication of a book of science which outranked any other book of the day that treated of the same subject, this negro became a very wealthy man.

Of course the book is now obsolete, science having made such great strides since his day.
This wealthy negro secretly gathered other free negroes together and organized a society that had a two-fold object.

The first object was to endeavor to secure for the free negroes all the rights and privileges of men, according to the teachings of Thomas Jefferson.
Its other object was to secure the freedom of the enslaved negroes the world over.

All work was done by this organization with the sole stipulation that it should be used for the furtherance of the two above named objects of the society, and for those objects alone.
"During slavery this organization confined its membership principally to free negroes, as those who were yet in physical bondage were supposed to have aspirations for nothing higher than being released from chains, and were, therefore, not prepared to eagerly aspire to the enjoyment of the highest privileges of freedom.

When the War of Secession was over and all negroes were free, the society began to cautiously spread its membership among the emancipated.
