Walt Whitman (1819-1892) was an American poet, journalist and essayist. His declamatory poem extolling the virtues of the pioneers of the American West (and, indeed, the virtues of trail-blazers in all walks of life) is entitled Pioneers! O Pioneers!:
Come my tan-faced children,
Follow well in order, get your weapons ready,
Have you your pistols? have you your sharp-edged axes?
Pioneers! O pioneers!
