There was some talk, even then, of skirting the rock wall and seeking a possible footway up, but the marshy jungle made that method look not only difficult but dangerous.

Terry dismissed the plan sharply.

“Nonsense, fellows! We’ve decided that. It might take months—we haven’t got the provisions. No, sir—we’ve got to take our chances. If we get back safe—all right. If we don’t, why, we’re not the first explorers to get lost in the shuffle. There are plenty to come after us.”

So we got the big biplane together and loaded it with our scientifically compressed baggage: the camera, of course; the glasses; a supply of concentrated food. Our pockets were magazines of small necessities, and we had our guns, of course—there was no knowing what might happen.

Up and up and up we sailed, way up at first, to get “the lay of the land” and make note of it.

Out of that dark green sea of crowding forest this high-standing spur rose steeply. It ran back on either side, apparently, to the far-off white-crowned peaks in the distance, themselves probably inaccessible.

“Let’s make the first trip geographical,” I suggested. “Spy out the land, and drop back here for more gasoline. With your tremendous speed we can reach that range and back all right. Then we can leave a sort of map on board—for that relief expedition.”

“There’s sense in that,” Terry agreed. “I’ll put off being king of Ladyland for one more day.”

So we made a long skirting voyage, turned the point of the cape which was close by, ran up one side of the triangle at our best speed, crossed over the base where it left the higher mountains, and so back to our lake by moonlight.

“That’s not a bad little kingdom,” we agreed when it was roughly drawn and measured. We could tell the size fairly by our speed. And from what we could see of the sides—and that icy ridge at the back end—“It’s a pretty enterprising savage who would manage to get into it,” Jeff said.
