Apologizes for not responding promptly to Estlin?s March 2nd letter. Thanks him for his interest in anti-slavery efforts in the US and tries to answer his questions regarding the number of abolitionist in the US (Samuel May Jr. says it is difficult to speculate but ́we are numerous enough to be feared ́); the ́stations in life of those devoting their time and money to the cause" (Samuel May Jr. says they are ́of every station in life, ́ and introduces a few Abolitionists, including Abby Kelley, Maria Weston Chapman, Eliza Lee Cabot Follen, Wendell Phillips, Edmund Quincy, and Ellis Gray Loring); the clergy?s attitude about slavery; the principle of ́No Union with Slaveholder ́; the laws in the slave states on teaching a slave to read; what course people should pursue if they are ́willing to become real Abolitionists ́; the effect of denouncing slavery ́in the abstract ́; whether ́the present effort of abolitionists more to waken the National conscience to the sin of slavery, and the necessity of some change, than for the purpose of pointing out definite measures ́; the principal objects for which the Abolitionist need funds; and ́what change of conduct toward the free colored people, on the part of the inhabitants of the North, is necessary to place them on a level with the white population. ́
