if not originating in a colder climate than exists south of the Arctic Circle?

Do they not still exist in the interior, or have they passed out with the great Auk, a former external resident?

Why are the latitudes nearest the poles the favorite fishing grounds for whales? Is not the interior ocean of fresh water their natural breeding ground and from thence passing out through Behring Strait and other channels into the outer waters? Can some scientist give us reliable information as to where whales propagate most, and why it is necessary for whaling expeditions to seek high latitudes for their catch?

The hole, fifteen hundred miles across, would not give any conscious impression of there being such an opening. You could not stand and inspect it like looking down a well. This hole opens into a new world unexplored by man, unless it is possible that Sir John Franklin and the Aeronaut Nansen unintentionally drifted in and were unable to navigate themselves out.

It must also, in marking out this theory, be admitted that as the center of the Earth is approached this opening must be somewhat enlarged, and must assume a concave shape from the center; such being the case, the diameter must increase from one thousand to two thousand miles or more, which is very likely to be the fact. With the motion or revolution of the Earth, the water would assume this condition on principle of the swinging of a pail of water over the head, and would merely be a placid ocean as boundless to the eye as the waters on the surface.

In these expanses of water, it is quite reasonable to presume that islands and large bodies of land may exist the same as outside, and that many fossil specimens thought to have existed on the outer surface in an early antiquity may have originated in the center of the Earth and may even still exist; their ancient skeletons having been thrown to the Earth’s surface by the centrifugal forces of water in the same way that all the different stratas of rock have been cast up and mixed in one grand conglomeration from the Earth’s center to its circumference. These facts seem clearly to prove by these migratory birds and animals: First an open sea; second it must be fresh water or mostly so; third, it must produce or contain desirable food elements different from what exist in the ocean on the outside, on which these birds can live when they reach their breeding grounds from which they are reported to return with largely augmented numbers. Now this consistent query can arise: Do they stop at a near point after passing this great boundary line of ice and find suitable and pleasant feeding grounds, or go on 500 or 1,000 miles farther? At that distance, the water is more likely to be modified in temperature and better adapted to their tastes and comfort. It seems quite right to assume that they come to inland seas, and pleasant bays, and sounds supplied with food from their shores and feeding grounds, rather than being supplied with anything existing on external parts of the Earth; otherwise, their supply must all be drawn under the ice belt or pass through this great Arctic filter. Again this thought comes up. How did these birds get sight of or learn of this internal feeding, and probably breeding ground? As migratory birds usually fly at great height, they would have an advantage over man in seeing this open ocean, as it is reasonable to think they may have bred as well as fed there. It is only a natural sequence of their migration in and out of this belt or ice circle, just as we recognize their flight north and south with the season’s changes.

If they go there by instinct, they merely do what is credited to the realm of life, considered lower in the scale of thoughts than man; but if by exploration and reason, then man must take a lower scale in calculation than the goose. To conclude this point. If birds live on vegetation, there must be an abundant supply of fresh water to produce it. If they live on fish, there must be the same sufficiency of fresh water in which to breed, feed, and live. If the birds breed, they must have hospitable shores on which to dwell and rest, and favoring skies to contribute to their various wants in order to exist.

Their instincts or reason will never take them where the conditions will not admit of food and drink, rest, shelter, and protection.

Ives begins by redefining 'crank' as a necessary agent of intellectual progress, listing Copernicus, Galileo, and Edison as fellow cranks who overturned old notions. This framing immediately signals that his hollow-Earth theory will be presented as a bold, rational challenge to established science, not as fringe fantasy. The opening chapter's tone—combative yet playful—sets expectations for a work that mixes personal conviction with observational evidence.

The table of contents reveals a systematic structure: after the introductory chapter, Ives moves through fire, water, icebergs, the Gulf Stream, earthquakes, volcanoes, rainfall, springs, glaciers, caves, artesian wells, oases, meteors, gravitation, and scientific theories. This suggests a methodical attempt to reinterpret familiar geological phenomena through the lens of a hollow interior.

A Crank's Defense of Unorthodoxy

Ives opens by embracing the label 'crank' with a historical roll call: 'Copernicus, Galileo, Columbus, Newton, Franklin' and later 'Daguerre, Watt, Howe, Edison, Marconi and Tesla.' He argues that without such figures, 'men's thoughts and opinions would all be the same.' This rhetorical strategy does two things: it aligns his own theory with proven scientific revolutions, and it preemptively dismisses critics as 'old-fogey and absurd notions.' The chapter is less about evidence than about establishing a persona—the misunderstood innovator. Readers should note that Ives's self-positioning colors every subsequent argument; he is not merely presenting data but defending a worldview against institutional inertia.

Water as a Sculptor of Continents

In Chapter XVIII, Ives turns to 'Surface Influences of Water,' offering two extended field observations. The first is the Rio Grande valley in New Mexico, where he describes 'hills, or immense mounds of land, like inverted deep pans, with flat bottoms' that he interprets as remnants of an eroded plain. He estimates the original level stood '100 feet high or more' above the current valley floor. The second example is near River Falls, Wisconsin, where similar flat-topped mounds support farms, with strata of 'gray sandstone, quite soft' gradually wasting away. Ives uses these to argue that water has removed 'vast areas and depths of land' over immense timescales. Notably, he avoids invoking his hollow-Earth mechanism here, instead building a case for gradual, observable erosion—a foundation for later claims about interior processes.

Salt Deposits and Missing Sources

A brief but telling passage in the excerpts asks: 'Where does this supply of salt water come from to leave hundreds of thousands of tons of salt each year?' This question, posed in the context of salt evaporation, hints at Ives's larger puzzle: conventional geology cannot account for the volume of salt deposited. The hollow-Earth theory, presumably, offers an answer—perhaps an internal ocean or continuous cycle. The excerpt cuts off before Ives provides his solution, but the pattern is clear: he identifies anomalies that standard models struggle to explain, then uses them as leverage for his alternative. Readers should watch for similar rhetorical moves throughout the book, where observational gaps become entry points for speculation.

Structure and Rhetorical Strategy

The book's organization—twenty chapters plus an appendix—follows a logical progression from basic elements (fire, water) to specific phenomena (earthquakes, volcanoes) and finally to theoretical synthesis. Ives's prose is direct and often colloquial, as when he describes the Rio Grande as 'an ordinary creek that gives little idea of the importance attached to such a stream.' He relies heavily on personal observation ('seen by the writer') and analogies (mounds like 'inverted deep pans'). The tone is that of an informed amateur addressing a general audience, not a specialist. This approach makes the work accessible but also means that technical arguments are simplified. For a first reading, pay attention to how Ives selects evidence: he favors visible, large-scale features (valleys, mounds, salt flats) that invite reinterpretation, while rarely engaging with counterarguments in depth.

Ives's The Hollow Earth is best approached as a period piece of scientific heterodoxy, where observation and speculation intertwine. The excerpts show a writer confident in his method: start with a puzzle, describe it vividly, then propose an unconventional solution. Readers should track how Ives moves from description to inference, and note where he leaves gaps—those are often where the hollow-Earth mechanism enters. The book rewards those who read with a critical eye for both its geological observations and its rhetorical craft.

There’s something touching about Ives’s stubborn faith in his hollow earth—the way he bends every pebble and salt flat to fit his longing for a world with more beneath the surface. It reminds me of the quiet devotion in A Lecture on Stained Glass — Inside the Classic, where light itself becomes proof of something hidden. Both feel like love letters to unseen depths, written by patient hands.
