The services began at half-past eleven o'clock, with prayer by our chaplain, Mr. Fowler, who is always, on such occasions, simple, reverential, and impressive. Then the President's Proclamation was read by Dr. W. H. Brisbane, a thing infinitely appropriate, a South-Carolinian addressing South-Carolinians; for he was reared among these very islands, and here long since emancipated his own slaves. Then the colors were presented to us by the Rev. Mr. French, a chaplain who brought them from the donors in New York. All this was according to the programme. Then followed an incident so simple, so touching, so utterly unexpected and startling, that I can scarcely believe it on recalling, though it gave the key-note to the whole day. The very moment the speaker had ceased, and just as I took and waved the flag, which now for the first time meant anything to these poor people, there suddenly arose, close beside the platform, a strong male voice, (but rather cracked and elderly,) into which two women's voices instantly blended, singing, as if by an impulse that could no more be repressed than the morning note of the song-sparrow,--
"My Country, 'tis of thee, Sweet land of liberty, Of thee I sing!"
People looked at each other, and then at us on the platform, to see whence came, this interruption, not set down in the bills. Firmly and irrepressibly the quavering voices sang on, verse after verse; others of the colored people joined in; some whites on the platform began, but I motioned them to silence. I never saw anything so electric; it made all other words cheap; it seemed the choked voice of a race at last unloosed. Nothing could be more wonderfully unconscious; art could not have dreamed of a tribute to the day of jubilee that should be so affecting; history will not believe it; and when I came to speak of it, after it was ended, tears were everywhere. If you could have heard how quaint and innocent it was! Old Tiff and his children might have sung it; and close before me was a little slave-boy, almost white, who seemed to belong to the party, and even he must join in. Just think of it!--the first day they had ever had a country, the first flag they had ever seen which promised anything to their people, and here, while mere spectators stood in silence, waiting for my stupid words, these simple souls burst out in their lay, as if they were by their own hearths at home! When they stopped, there was nothing to do for it but to speak, and I went on; but the life of the whole day was in those unknown people's song.
