The Ladies' Anti-Slavery Society of Boston was called last fall, to a severe trial of their faith and constancy. They were mobbed by "the gentlemen of property and standing," in that city at their anniversary meeting, and their lives were jeoparded by an infuriated crowd; but their conduct on that occasion did credit to our sex, and affords a full assurance that they will _never_ abandon the cause of the slave. The pamphlet, Right and Wrong in Boston, issued by them in which a particular account is given of that "mob of broad cloth in broad day," does equal credit to the head and the heart of her who wrote it. I wish my Southern sisters could read it; they would then understand that the women of the North have engaged in this work from a sense of _religious duty_, and that nothing will ever induce them to take their hands from it until it is fully accomplished. They feel no hostility to you, no bitterness or wrath; they rather sympathize in your trials and difficulties; but they well know that the first thing to be done to help you, is to pour in the light of truth on your minds, to urge you to reflect on, and pray over the subject. This is all _they_ can do for you, _you_ must work out your own deliverance with fear and trembling, and with the direction and blessing of God, _you can do it_. Northern women may labor to produce a correct public opinion at the North, but if Southern women sit down in listless indifference and criminal idleness, public opinion cannot be rectified and purified at the South. It is manifest to every reflecting mind, that slavery must be abolished; the era in which we live, and the light which is overspreading the whole world on this subject, clearly show that the time cannot be distant when it will be done. Now there are only two ways in which it can be effected, by moral power or physical force, and it is for _you_ to choose which of these you prefer. Slavery always has, and always will produce insurrections wherever it exists, because it is a violation of the natural order of things, and no human power can much longer perpetuate it. The opposers of abolitionists fully believe this; one of them remarked to me not long since, there is no doubt there will be a most terrible overturning at the South in a few years, such cruelty and wrong, must be visited with Divine vengeance soon. Abolitionists believe, too, that this must inevitably be the case, if you do not repent, and they are not willing to leave you to perish without entreating you, to save yourselves from destruction; well may they say with the apostle, "am I then your enemy because I tell you the truth," and warn you to flee from impending judgments.
