   They unfurled the flag at the start of the festival.
   BEHIND him lay the gray Azores, / Behind the Gates of Hercules; / Before him not the ghost of shores, / Before him only shoreless seas. // The good mate said: “Now must we pray, / For lo! the very stars are gone. / Brave Admiral, speak, what shall I say?” / “Why, say, ‘Sail on! sail on! and on!’” “My men grow mutinous day by day; / My men grow ghastly wan and weak.” / The stout mate thought of home; a spray / Of salt wave washed his swarthy cheek. // “What shall I say, brave Admiral, say, / If we sight naught but seas at dawn?” / “Why, you shall say at break of day, / ‘Sail on! sail on! sail on! and on!’” They sailed and sailed, as winds might blow, / Until at last the blanched mate said: / “Why, now not even God would know / Should I and all my men fall dead. // These very winds forget their way, / For God from these dread seas is gone. / Now speak, brave Admiral, speak and say”— / He said: “Sail on! sail on! and on!” They sailed. They sailed. Then spake the mate: / “This mad sea shows his teeth to-night. / He curls his lip, he lies in wait, / With lifted teeth, as if to bite! // Brave Admiral, say but one good word: / What shall we do when hope is gone?” / The words leapt like a leaping sword: / “Sail on! sail on! sail on! and on!” Then, pale and worn, he kept his deck, / And peered through darkness. Ah, that night / Of all dark nights! And then a speck— / A light! A light! A light! A light! // It grew, a starlit flag unfurled! / It grew to be Time’s burst of dawn. / He gained a world; he gave that world / Its grandest lesson: “On! sail on!” 1892, Joaquin Miller, Columbus
