J. T. Woodbury. Hymn. (To be sung by the Audience to the tune of Old Hundred.) O God, supreme o'er earth and skies, To Thee our fathers' suppliant eyes Were rais'd for help, when loud the alarm Of battle call'd the brave to arm Here, on this consecrated ground, Where sleeps their martyr'd dust around, Their sons exulting raise to Thee Their grateful hymn of Jubilee The blood that dyed that day the field, A nation's independence seal'd That blood sent up its cry to Thee, A nation's pledge of Victory. Our father's deeds, in deathless song, Time in his course shall bear along; Their sons, still happy, brave and free, Shall own their boundless debt to Thee. Oration by the Hon. Robert Rantoul, Jr. Music.
