This very day the writer of this has been present at a solemn religious festival in the national capital, given at the home of a portion of those fugitive slaves who have fled to our lines for protection,--who, under the shadow of our flag, find sympathy and succor. The national day of thanksgiving was there kept by over a thousand redeemed slaves, and for whom Christian charity had spread an ample repast. Our sisters, we wish you could have witnessed the scene. We wish you could have heard the prayer of a blind old negro, called among his fellows John the Baptist, when in touching broken English he poured forth his thanksgivings. We wish you could have heard the sound of that strange rhythmical chant which is now forbidden to be sung on Southern plantations,--the psalm of this modern exodus,--which combines the barbaric fire of the Marseillaise with the religious fervor of the old Hebrew prophet:--
Oh, go down, Moses,
Way down into Egypt's land!
Tell King Pharaoh
To let my people go!
Stand away dere,
Stand away dere,
And let my people go!
