Absorbing adventure novel about a sky-boat voyage to the Matterhorn. We saw the earth beneath us arched like a reversed sky a great gulf of air, deepest in the middle, and with cliff-like shores of Alpine ranges. We were in the sky, but a strange sky of intense Prussian blue. Clouds formed below us, the evaporization taking place from snow-peaks warming under the sun; but above and around us was that deep, uncanny sea of metallic blue, marvelous in its luminous depth.
Reprint of the original edition from 1897.
