Even the least scientific minded of the party gasped in amazement at what Dodd had. It resembled nothing so much as an enormous beetle. As a matter of fact, it was an insect, for it had the three sections that characterize this class, but it was merely the shell of one. Between four and five feet in height, when Dodd stood it on end, it could now be seen to consist of the hard exterior substance of some huge, unknown coleopter. This substance, which was fully three inches thick over the thorax, looked as hard as plate armor. "What is it?" gasped Storm again. * * * * * Tommy Travers made answer, for James Dodd was evidently incapable of speech, more from emotion than from the force with which he had landed backward in the snow. "We found it at the pole, Captain," he said. "At least, pretty near where the pole ought to be. We ran into a current of warm air or something. The snow had melted in places, and there were patches of bare rock. This thing was lying in a hollow among them." "If I didn't see it before my eyes, I'd think you crazy, Tommy," said Storm with some asperity. "What is it, a crab?" "Crab be damned!" shouted Jim Dodd, suddenly recovering his faculties. "My God, Captain Storm, don't you know the difference between an insect and a crustacean? This is a fossil beetle. Don't you see the distinguishing mark of the coleoptera, those two elytra, or wing-covers, which meet in the median dorsal line? A beetle, but with the shell of a crustacean instead of mere chitin. That's what led you astray, I expect. God, what a tale we'll have to tell when we get back to New York! We'll drop everything else, and spend years, if need be, looking for other specimens." "Like fun you will!" shouted Higby, the astronomer of the party. "Lemme tell you right here, Dodd, nobody outside the Museum of Natural History is going to care a damn about your old fossils. What we're going to do is to march straight to the true pole, and spend a year taking observations and parallaxes. If Einstein's brochure, in which he links up gravitation with magnetism, is correct--" "Fossil beetles!" Jim Dodd burst out, ignoring the astronomer. "That means that in the Tertiary Era, probably, there existed forms of life in the antarctic continent that have never been found elsewhere. Imagine a world in which the insect reached a size proportionate to the great saurians, Captain Storm! I'll wager poor Bram discovered this. That's why he stayed behind when the Greystoke Expedition came within a hundred miles of the pole. I'll wager he's left a cairn somewhere with full details inside it. We've got to find it. We--" * * * * * But Jim Dodd, suddenly realizing that the rest of the party could hardly be said to share his enthusiasm in any marked degree, broke off and looked sulky. "You say you found this thing pretty nearly upon the site of the true pole?" Captain Storm asked Tommy.
