"Our only hope to navigate the air," continued Pedro, "must, in the nature of things, be found in devices heavier than the air—in flying machines or aeroplanes. Reason by analogy. Look at the bird...."

"Once you desired me to look at the fish," said Luis. "You said the steamboat ought to wriggle through the water...."

"Do be serious, Luis," said Pedro in conclusive tones. "Exercise common-sense. Does man fly? No. Does the bird fly? Yes. Then, if man would fly, let him imitate the bird. Nature has made the bird. Nature never goes wrong."

[A] In the early morning of 12th May 1902 M. Augusto Severo, accompanied by his mechanician, Sachet, started from Paris on a first trial with the "Pax," the invention and construction of M. Severo. The "Pax" rose at once to a height almost double that of the Eiffel Tower, when, for reasons not precisely known, it exploded, and came crashing to earth with its two passengers. The fall took eight seconds to accomplish, and the luckless experimenters were picked up broken and shapeless masses.

"Por mares nunca d'antes navegados"—
