The great and good work of restoring liberty to the captive, and fitting him to fill that station in the scale of being, from which he has been forced by the domineering spirit of power and usurpation, may be considered as little more than begun. How many thousands of miserable wretches yet languish in slavery, in these United States, to whom the light of morn, which should awaken all nature alike to harmony and joy, affords, perhaps, no other consolation save the solitary certainty, that one day more is taken from the long period of their sufferings--This is not all--In vain do you liberate the Africans, while you neglect to furnish him with the means of properly providing for himself, and of becoming an useful member of the community. This subject alone opens an extensive field for active benevolence, and justly demands the exercise of a large portion of the talents and labours of the friends of emancipation. To effect these desirable objects, so importunately called for by every sentiment of a feeling heart, union and concentration of energy appear to be indispensible. The societies should never be found in the pursuit of incongruous measures, but act in concert; and this cannot, perhaps be better accomplished than by a free and liberal interchange of information, whence useful knowledge should diverge to each society, communicating life, energy, and consistency to the whole. The advantages resulting from this institution may be known by past experience; but as an additional instance of the good effects flowing from it, we refer you to the addresses forwarded this year to the Convention, and printed in the minutes; in which you will perceive, and especially in the one from New York, much valuable matter. That society mentions a species of kidnapping, which to the disgrace of humanity, has been carried on in that city in a manner at once evincing the barefaced hardiness of its perpetrators, and the wicked and cunning arts practiced, by the enemies of freedom, on an oppressed people. There is good reason to believe, that similar practices are secretly pursued in other parts of the Union. We therefore earnestly press your vigilant attention to the subject, in order that if any other persons should be engaged in this nefarious traffic, they may be made to suffer that exposure and punishment which the enormity of the crime so richly merits.
