all, held a persistent suggestion of the aërial. How it could have undergone its tremendously complex evolution on a new-born earth in time to leave prints in archæan rocks was so far beyond conception as to make Lake whimsically recall the primal myths about Great Old Ones who filtered down from the stars and concocted earth life as a joke or mistake; and the wild tales of cosmic hill things from outside told by a folklorist colleague in Miskatonic's English department.

Naturally, he considered the possibility of the pre-Cambrian prints having been made by a less evolved ancestor of the present specimens, but quickly rejected this too-facile theory upon considering the advanced structural qualities of the older fossils. If anything, the later contours showed decadence rather than higher evolution.

The size of the pseudofeet had decreased, and the whole morphology seemed coarsened and simplified. Moreover, the nerves and organs, just examined, held singular suggestions of retrogression from forms still more complex. Atrophied and vestigial parts were surprisingly prevalent. Altogether, little could be said to have been solved; and Lake fell back on mythology for a provisional name—jocosely dubbing his finds "The Elder Ones."

At about two-thirty a.m., having decided to postpone further work and get a little rest, he covered the dissected organism with a tarpaulin, emerged from the laboratory tent, and studied the intact specimens with renewed interest.

The ceaseless antarctic sun had begun to limber up their tissues a trifle, so that the head points and tubes of two or three showed signs of unfolding; but Lake did not believe there was any danger of immediate decomposition in the almost subzero air. He did, however, move all the undissected specimens closer together and throw a spare tent over them in order to keep off the direct solar rays. That would also help to keep their possible scent away from the dogs, whose hostile unrest was really becoming a problem, even at their substantial distance and behind the higher and higher snow walls, which an increased quota of the men were hastening to raise around their quarters.

He had to weight down the corners of the tent cloth with heavy blocks of snow to hold it in place amidst the rising gale, for the titan mountains seemed about to deliver some gravely severe blasts. Early apprehensions about sudden antarctic winds were revived, and under Atwood's supervision precautions were taken to bank the tents, new dog corral, and crude aëroplane shelters with snow, on the
