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. Take them editors thet's crowin' Like a cockerel three months old, — Don't ketch any on 'em goin', Though they be so blasted bold; Aint they a prime lot o' fellers? 'Fore they think on't guess they'l sprout (Like a peach thet's got the yellers), With the meanness bustin' out.
