MY FRIEND:-- I have found no moment till the present that I could devote to a compliance with your request, and I am now probably too late. However, let me hastily proffer a few suggestions to opponents of slavery, which I trust may not be found unprofitable. I would say, then: 1. Do not choose to separate and isolate yourselves from the general movement of humanity, save as you may be constrained to oppose certain eddies of that movement. Had WILBERFORCE, CLARKSON, and their associate pioneers in the cause of British abolition, seen fit to cut themselves loose from all preëxisting sects and parties, and for a special anti-slavery church and party, I think the triumph of their cause would have been still unattained. 2. Do not refuse to do a little good because you would much prefer to do a greater which is now unattainable. The earth revolves in her vast orbit gradually; and he who has done whatever good he can, need not reproach himself for his inability to do more. 3. Be foremost in every good work that the community around you _will_ appreciate,--not _because_ they will appreciate it, but because their appreciation and sympathy will enable you to do good in other spheres, and do it more effectually. 4. Be preëminent in your consideration and regard for the rights and wrongs of labor in your own circle, even the rudest and humblest. An abolitionist who hires his linen made up at the lowest market rate, and pays his wash-woman in proportion, will do little good to the anti-slavery or any other philanthrophic cause. The man of liberal culture and generous heart who unostentatiously tries to elevate the most depressed to his own level, is doing a good work against slavery, however unconsciously. 5. Have faith, with a divine patience; man is privileged to labor for a good cause, but the glory of its success must redound to his Maker. Next to a great defeat, the most fatal event for slavery would be a great triumph. Doubtless, the bolts are now forging in some celestial armory destined to strike the shackles from the limbs of the bondman, and cleanse the land from the foulest and blackest iniquity ever organized and legalized in the christian world. The shout of deliverance may come when it is least expected,--nay, the very means employed to render its coming impossible, will probably secure and hasten it. For that and every other needed reform, let the humane and hopeful strive, not despairing in the densest midnight, and realizing that the darkest hour is often that preceding the dawn. Let them, squandering no opportunity, and sacrificing no principle, “Learn to labor, and to wait.” Horace Greeley THE GREAT EMANCIPATION.
