The Arkansas traveller's songster: (c.1864) "containing the celebrated story of the Arkansas traveller, with the music for violin or piano. And also an extensive and choice collection of new and popular comic and sentimental songs."

Lays of the Scottish cavaliers, and other poems by William Edmondstoune Aytoun (1852).

The spirituals in Hampton and its students, incidentally, begin on page 171, and are indexed on page 256.
