Under his rule are many thousands of the Nomes, who are queerly shaped but powerful sprites that labor at the furnaces and forges of their king, making gold and silver and other metals which they conceal in the crevices of the rocks, so that those living upon the earth's surface can only find them with great difficulty.

"If the crust is of sufficient thickness we shall come to a final stop between six and seven hundred miles beneath the earth's surface; but during the last hundred and fifty miles of our journey we shall be corpses.

Of course, as every one knew, kinky-haired cannibals no longer obtained on the earth's surface, much less ran around with nothing on, chopping off one another's heads, and, on occasion, a white man's head as well.

We are thus brought to the question which has been largely discussed by naturalists, namely, whether species have been created at one or more points of the earth's surface. Undoubtedly there are very many cases of extreme difficulty, in understanding how the same species could possibly have migrated from some one point to the several distant and isolated points, where now found.

Too, she bad seen me conversing with other men upon the earth's surface. She had seen the arrival of the caravan of books and arms, and ammunition, and the balance of the heterogeneous collection which I had crammed into the cabin of the iron mole for trans-portation to Pellucidar.

A snake who could make himself comfortable in a quagmire, a hundred feet deep, would be protected on the outskirts by such stupendous morasses as now no longer exist, or which, if they exist anywhere at all, can be on very few places on the earth's surface. Far be it from me to say that in more elemental times such things could not have been.

And this is the dissolution:-- In plants that grow in the earth, as well as in animals that move on the earth's surface, fertility and sterility of soul and body occur when the circumferences of the circles of each are completed, which in short-lived existences pass over a short space, and in long-lived ones over a long space.

These were important, because, heavily loaded, they were to help lessen the fall of the projectile, when drawn by the lunar attraction (after having passed the point of neutral attraction) on to the moon's surface; a fall which ought to be six times less rapid than it would have been on the earth's surface, thanks to the difference of bulk.

Just as we should travel DOWN if we began our existence fifty miles above the earth's surface.'

This was my curious labor all summer -- to make this portion of the earth's surface, which had yielded only cinquefoil, blackberries, johnswort, and the like, before, sweet wild fruits and pleasant flowers, produce instead this pulse.

They saw a landscape with mountains and plains, lakes and rivers, very like those upon the earth's surface; but all the scene was splendidly colored by the variegated lights from the six suns.

At a sudden turning of the corridor, daylight flooded them and Bukawai stepped out into a small, circular basin in the hill, apparently the crater of an ancient volcano, one of those which never reached the dignity of a mountain and are little more than lava-rimmed pits closed to the earth's surface.
