In 1818, John Cleves Symmes Jr. suggested that the Earth consisted of a hollow shell about 800 miles (1,300 km) thick, with openings about 1400 miles (2,300 km) across at both poles with 4 inner shells each open at the poles. Symmes became the most famous of the early Hollow Earth proponents. He proposed making an expedition to the North Pole hole, thanks to efforts of one of his followers, James McBride, but the new President of the United States, Andrew Jackson, halted the attempt.
Though Symmes himself never wrote a book about his ideas, several authors published works discussing his ideas. James McBride, who was his devoted friend and disciple, published a small volume in 1826 in exposition and defense of his theory, describes it as follows:
"According to Symmes's Theory, the earth, as well as all the celestial orbicular bodies existing in the universe, visible and invisible, which partake in any degree of a planetary nature, from the greatest to the smallest, from the sun down to the most minute blazing meteor or falling star, are all constituted, in a greater or less degree, of a collection of spheres, more or less solid, concentric with each other, and more or less open at their poles.
According to him, the planet which has been designated the Earth is composed of at least five hollow concentric spheres, with spaces between each, an atmosphere surrounding each; and habitable as well upon the concave as the convex surface. All of these spheres are widely open at their poles. The north polar opening of the sphere we inhabit is believed to be about four thousand miles in diameter, and the southern above six thousand.
Each of the spheres composing the earth, as well as those constituting the other planets throughout the universe, is believed to be habitable both on the inner and outer surface; and lighted and warmed according to those general laws which communicate light and heat to every part of the universe. The light may not, indeed, be so bright, nor the heat so intense, as is indicated in high northern latitudes -- about where the verge is supposed to commence -- by the paleness of the sun, and darkness of the sky; facts, which navigators who have visited these regions confirm; yet they are no doubt sufficiently lighted and warmed to promote the propagation and support of animal and vegetable life."
