"Emblem of much, and of our Age of Hope itself," Carlyle called the balloon of his time, born to mount majestically but "unguidably" only to tumble "whither Fate will." But the aircraft of our day is guidable, and our Age of Hope is not rudderless nor at the mercy of Fate.
BIBLIOGRAPHICAL NOTE GENERAL A clear, non-technical discussion of the basis of all industrial progress is "Power", by Charles E.Lucke (1911), which discusses the general principle of the substitution of power for the labor of men.
Many of the references given in "Colonial Folkways", by C.M.
Andrews ("The Chronicles of America", vol.IX), are valuable for an understanding of early industrial conditions.

The general course of industry and commerce in the United States is briefly told by Carroll D.
Wright in "The Industrial Evolution of the United States" (1907), by E.
L.Bogart in "The Economic History of the United States" (1920), and by Katharine Coman in "The Industrial History of the United States" (1911).
