O, hemlock tree O, hemlock tree! how faithful are thy branches. etc.

The Rebel version ran:

MARYLAND.

The despot's heel is on thy shore,
Maryland!
His touch is at thy temple door,
Maryland!
Avenge the patriotic gore
That flecked the streets of Baltimore,
And be the battle queen of yore,
Maryland! My Maryland!

Hark to the wand'ring son's appeal,
Maryland!
My mother State, to thee I kneel,
Maryland!
For life and death, for woe and weal,
Thy peerless chivalry reveal,
And gird thy beauteous limbs with steel,
Maryland! My Maryland!

Thou wilt not cower in the duet,
Maryland!
Thy beaming sword shall never rust
Maryland!
Remember Carroll's sacred trust,
Remember Howard's warlike thrust--
