There have been other “voyages to the moon,” but none of higher merit than the one just mentioned. That of Bergerac is utterly meaningless. In the third volume of the “American Quarterly Review” will be found quite an elaborate criticism upon a certain “journey” of the kind in question—a criticism in which it is difficult to say whether the critic most exposes the stupidity of the book, or his own absurd ignorance of astronomy. I forget the title of the work; but the _means_ of the voyage are more deplorably ill conceived than are even the _ganzas_ of our friend the Signor Gonzales. The adventurer, in digging the earth, happens to discover a peculiar metal for which the moon has a strong attraction, and straightway constructs of it a box, which, when cast loose from its terrestrial fastenings, flies with him, forthwith, to the satellite. The “Flight of Thomas O’Rourke,” is a _jeu d’ esprit_ not altogether contemptible, and has been translated into German. Thomas, the hero, was, in fact, the gamekeeper of an Irish peer, whose eccentricities gave rise to the tale. The “flight” is made on an eagle’s back, from Hungry Hill, a lofty mountain at the end of Bantry Bay. In these various _brochures_ the aim is always satirical; the theme being a description of Lunarian customs as compared with ours. In none is there any effort at _plausibility_ in the details of the voyage itself. The writers seem, in each instance, to be utterly uninformed in respect to astronomy. In “Hans Pfaall” the design is original, inasmuch as regards an attempt at _verisimilitude,_ in the application of scientific principles (so far as the whimsical nature of the subject would permit), to the actual passage between the earth and the moon. (*2) The zodiacal light is probably what the ancients called Trabes. Emicant Trabes quos docos vocant.—Pliny, lib. 2, p. 26. (*3) Since the original publication of Hans Pfaall, I find that Mr. Green, of Nassau balloon notoriety, and other late aeronauts, deny the assertions of Humboldt, in this respect, and speak of a decreasing inconvenience,—precisely in accordance with the theory here urged in a mere spirit of banter.
