The annihilation of Spain came about after the following manner: In the year 1917 the world rejoiced at the prospect of a permanent solution of the war problem. The new devices invented and perfected by the deviltry of man, to be employed in the destruction of his fellow men, had reached in that year such a degree of perfection that war simply meant the wholesale destruction or total annihilation of those who engaged in it. In 1917 ærial navigation was practically solved, and a new and vast element had [A New Element in War.] opened its possibilities to the will of man. At the close of the nineteenth century the "blue etherial" was wholly unobstructed in its vast extent and still defied the skill of our best inventors. Prof. Langley and his disciples had not yet solved the great question of ærial navigation. In 1899 this most inviting and ever tempting field of research still remained an unsolved mystery. The old fashioned balloon, with no will or control of its own, subject to the whim or caprice of every breath of air, was the best apology we could offer in 1899 for purposes of ærial navigation. In 1917 the problem of ærial navigation had been practically solved by Tesla, in [Ærial Navigation Perfected.] whose brain many profound secrets of nature had long been harbored. With the aid and potentiality of electricity, (the slave of the twentieth century), ærial navigation had been perfected. One of the first devices invented for use in the air was the ærial warship, operated and controlled by electricity. Loaded with a quarter ton of dynamite, these deadly warships, without anyone to navigate them could be made to hover over a city and threaten its population with total annihilation. They were popularly called "death angels." The sight of one of the warships blanched the cheeks of the most intrepid, filling the city or town over which it hovered with utmost consternation.
