Tarzan at the Earth's core

by Edgar Rice Burroughs

"I shall fly directly over the forest as far as I think it at all likely that they could have marched in the time that they have been absent, assuming that they became absolutely confused and have traveled steadily away from the ship. As soon as I have gained sufficient altitude to make any observation I shall try and spot some natural landmark, like a mountain or a body of water, near the ship and from time to time, as I proceed, I shall make a note of similar landmarks. I believe that in this way I can easily find my way back, since at the furthest I cannot proceed over two hundred and fifty miles from the O-220 and return to it with the fuel that I can carry.

"After I have reached the furthest possible limits that I think the party could have strayed, I shall commence circling, depending upon the noise of the motor to attract their attention and, of course, assuming that they will find some means of signaling their presence to me, which they can do even in wooded country by building smudges."

"You expect to land?" inquired Zuppner, nodding at the heavy rifle which Gridley carried.

"If I find them in open country, I shall land; but even if I do not find them it may be necessary for me to come down and my recent experiences have taught me not to venture far in Pellucidar without a rifle."

After a careful inspection, Gridley shook hands with the three remaining officers and bid farewell to the ship's company, all of whom were anxious observers of his preparation for departure.

"Good-bye, old man," said Zuppner, "and may God and luck go with you."

Gridley pressed the hand of the man he had come to look upon as a staunch and loyal friend, and then took his seat in the open cockpit of the scout plane. Two mechanics spun the propeller, the motor roared and a moment later the block was kicked away and the plane rolled out across the grassy meadowland towards the forest at the far side. The watchers saw it rise swiftly and make a great circle and they knew that Gridley was looking for a landmark. Twice it circled above the open plain and then darted away across the forest.

It had not been until he had made that first circle that Jason Gridley had realized the handicap that this horizonless landscape of Pellucidar had placed upon his chances of return. He had thought of a mountain standing boldly out against the sky, for such a landmark would have been almost constantly within the range of his vision during the entire flight.

There were mountains in the distance, but they stood out against no background of blue sky nor upon any horizon. They simply merged with the landscape beyond them, curving upward in the distance. Twice he circled, his keen eyes searching for any outstanding point in the topography of the country beneath him, but there was nothing that was more apparent than the grassy plain upon which the O-220 rested.

He felt that he could not waste time and fuel by searching longer for a landmark that did not exist, and while he realized that the plain would be visible for but a comparatively short distance he was forced to accept it as his sole guide in lieu of a better one.
