From OpenwaterpediaMercedes Gleitze in commemoration of her 30-hour endurance swim of 25-26 February 1930:
 One Great Achievement More
Felicitations! Neptune smiles on thee; Thou'st won thy test in Cork upon the Lee. Methinks thy trust in One who e'er hath power Hath strengthened thee throughout each stressful hour.
Aye, music's charms were glorious to thine ear; From Irish hearts sprang forth a wondrous cheer. One great achievement more, fresh glory, yet... On, onward still, thy pluck we'll n e'er forget.
Excelsior's thy motto ... Not in vain- Bravo! The world's record thou must gain. Then, laurel-crowned thy future sure will be. Adieu! Good luck! from Cork upon the Lee.
