Ir.appears, frorn a correspondence in the N. Y. Observer, that the Board has now in ksemploy a slaveholder, as a Missionary, named J. Leighton Wilson. TÃ¼e fact of his bewg a slaveholder was knovvn to the eecretaries of the Board before his connection with it in 1836, and they conferred with hira on the subject. A letter which he wrote to Rev. R. Anderson, dated Cape Palmas, June 12, 1836, has just been published, in which he avows the fact of his being a elaveholder, and justifies it, because the laws of his native state will not permit him to emancÃpate them in lts limits, and they are unwilling to go elsewhere - they prefer bondage on their native soil to freedom in other parts of the world. Should Mr. W. set thera free regardless of the law, they would be arrested and exposed to public sale, and fall into bond agp ten fold worse. He says: "They havethe offer of freedom Ã¯f they will go where Ihey can enjoy and maintain it. Uut they will not, and thus they cotnpel roe to be a master and austain the odious character of a slaveholder ." Mr. W. had directed the proceeds of the labor of the slaves lo be carefully laid up for three years, to be appropriated to their use at the expiration of that time, it they would emigrale. He presented this to them as an inducement - it was the most judicious course he could deviso. Part of hisfslaves he had inhented, and part he had acquired with his wife. In hisleiter he speaks of "some of his rnissionary friends who were similarly situated," referring doubtlees to the fact of their beiog slaveholders. Thus it seems the Board have knowingly employed at least one missionary slavehold er for SIX YEARS! What now becomes ofthe declaration, made in August, 1841, that "this Board can sustain no relation to slavery that implies approbation ofthe sys tem,and as a Board they have no connection or sympathy with it."
