Strona 138 - Spanish sailors with bearded lips, And the beauty and mystery of the ships, And the magic of the sea. And the voice of that wayward song Is singing and saying still: 'A boy's will is the wind's will, And the thoughts of youth are long, long thoughts.

Strona 144 - Ef you're arter folks o' gumption, You've a darned long row to hoe.
