Most that I have done and suffered in the service of our cause has been in public, and I have received much encouragement at every step of the way. You, on the other hand, have labored in a private way. I have wrought in the day - you in the night. I have had the applause of the crowd and the satisfaction that comes of being approved by the multitude, while the most that you have done has been witnessed by a few trembling, scarred, and foot-sore bondmen and women, whom you have led out of the house of bondage, and whose heartfelt ' God bless you ' has been your only reward. The midnight sky and the silent stars have been the witnesses of your devotion to freedom and of your heroism. Excepting John Brown - of sacred memory - I know of no one who has willingly encountered more perils and hardships to serve our enslaved people than you have. Much that you have done would seem improbable to those who do not know you as I know you. It is to me a great pleasure and a great privilege to bear testimony to your character and your works, and to say to those to whom you may come, that I regard you in every way truthful and trustworthy.
