Arqtiq
 The plot of Arqtiq involves a woman who invents an aircraft, a sort of hybrid of airplane and balloon. She decides to fly it to the North Pole, accompanied by her husband, father, and friends. After crossing the continent to New York, they travel northwards and reach the Pole. At first they perceive only a flat plain surrounded with icebergs; but the narrator detects a crystal city beneath the ice. The aeronauts land and meet the inhabitants, called the Arq. The Arq maintain a culture of gender equality and high technology. Communication is facilitated by the Arqs' telepathy; the narrator soon develops the same psychic ability. Despite their isolation, the Arq are devout Christians. Adolph's Arqtiq has been characterized as "An eccentric novel combining elements of science fiction and religious fundamentalism," and an "exuberantly incoherent" book that also touches upon the work of John Symmes, a lunar meteorite, and "lunar people who are tiny and nasty."
