“There are lots of things you never heard of; I built this monoplane, without help from any one; it embodies a number of new principles, one of which is the ability to keep in the air for twelve hours without renewing the gasoline; I mix a certain chemical with that fluid which increases its power tenfold; I shall not rest until it is multiplied a hundred times.”
