“That I cannot say,” was the reply, “or even that he will hear you at all. But, pardon! I did not know that the angels of Paradise accompanied the Aerians on their voyages. Descend in peace, my master will receive you.”

As he was speaking Alma, crowned with her crystal wings, and radiant with a beauty which, to the Moslem’s eyes, seemed something superhuman, had come from the after part of the vessel to Alan’s side. It was the first time that he had ever seen a woman of Aeria; and, with the innate chivalry of his race, he paid his involuntary homage to her as he would have done to an incarnation of one of the poetic dreams of his faith.
