The student of the so-called Negro problem of today may find it profitable to study the methods of persons thus concerned more than a century ago. What their plans were, what machinery they constructed for carrying them out, and the hopes they had for ultimate success, will furnish much material for reflection for social workers. There is published below, therefore, a number of the annual appeals of the American Convention of Abolition Societies to the various branches, setting forth the annual review of the work, the general survey of results obtained and the ways and means to carry it forward to a successful completion. TO THE ANTISLAVERY GROUPS _To the Society for promoting the abolition of Slavery, Ec._ It is with peculiar pleasure we inform you, that the Convention of Delegates, from most of the Abolition Societies formed in the United States, met in this city, have, with much unanimity, gone through the business which came before them. The advantages to be derived from this meeting are so evident, that we have agreed earnestly to recommend to you, that a similar meeting be annually convened, until the great object of our association--the liberty of our fellowmen--shall be fully and equivocally established. To obtain this important end, we conceive that it is proper, constantly to have in view the necessity of using our utmost and unremitting endeavors to abolish slavery, and to protect and meliorate the condition of the enslaved, and of the emancipated. The irresistible, though silent progress of the principles of true philosophy, will do much for us; but, placed in a situation well adapted to promote these principles, it surely becomes us to improve every occasion of forwarding the great designs of our institutions. For this purpose, we think it proper to request you to unite with us, in the most strenuous exertions, to effect a compliance with the laws in favour of emancipation; and, where these laws are deficient, respectful applications to the State-Legislatures should not be discontinued, however unsuccessful they may prove.--Let us remember, for our consolation and encouragement in these cases, that, although interest and prejudice may oppose, yet the fundamental principles of our government, as well as the progressive and rapid influence of reason and religion, are in our favour--and let us never be discouraged by a fear of the event, from performing any task of duty, when clearly pointed out; for it is an undoubted truth--that no good effort can ever be entirely lost.
