He did not want to be in New York, or Washington, or any other city; the landscape of America was haunted for him. He would leave it, but he would not open himself to the cruel longing for his own language, the sight of familiar customs and manners. From his hotel in New York he made excursions to various steamship agencies and travel bureaus. He had seen many lands, and his Wanderlust demanded novelty. For days he was undecided.

It was a chance group of photographs in a Sunday newspaper that excited his first real interest. One of the pictures was of a man—erect, white-haired, tanned, clear-eyed—Professor Daniel Hardin—a procession of letters—head of the new expedition to Yucatan. The other pictures were of ruined temples, unpiled stone causeways, jungle. He thought instantly that he would like to attach himself to the party.

Many factors combined to make the withdrawal offered by an expedition ideal. The more Hugo thought about it, the more excited he became. The very nascency of a fresh objective was accompanied by and crowded with new hints for himself and his problems. The expedition would take him away from his tribulations, and it would not entirely cut him off from his kind: Professor Hardin had both the face and the fame of a distinguished man.

A thought that had been in the archives of his mind for many months came sharply into relief: of all human beings alive, the scientists were the only ones who retained imagination, ideals, and a sincere interest in the larger world. It was to them he should give his allegiance, not to the statesmen, not to industry or commerce or war. Hugo felt that in one quick glimpse he had made a long step forward.

Another concept, far more fantastic and in a way even more intriguing, dawned in his mind as he read accounts of the Maya ruins which were to be excavated. The world was cluttered with these great lumps of incredible architecture. Walls had been builded by primitive man, temples, hanging gardens, obelisks, pyramids, palaces, bridges, terraces, roads—all of them gigantic and all of them defying the penetration of archæology to find the manner of their creation. Was it not possible—Hugo's heart skipped a beat when it occurred to him—that in their strange combination of ignorance and brilliance the ancients had stumbled upon the secret of human strength—his secret! Had not those antique and migratory peoples carried with them the formula which could be poured into the veins of slaves, making them stronger than engines? And was it not conceivable that, as their civilizations crumbled, the secret was lost, together with so many other formulæ of knowledge?

He could imagine plumed and painted priests with prayer and sacrifice cutting open the veins of prehistoric mothers and pouring in the magic potion. When the babies grew, they could raise up the pyramids, walls, and temples; they could do it rapidly and easily. A great enigma was thus resolved. He set out immediately to locate Professor Hardin and with difficulty arranged an interview with him.

Preparations for the expedition were being carried on in an ordinary New York business office. A secretary announced Hugo and he was conducted before the professor. Daniel Hardin was no dusty pedagogue. His knowledge was profound and academic, his books were authoritative, but in himself he belonged to the type of man certain to succeed, whatever his choice of occupation. Much of his life had been spent in field work—arduous toil in bizarre lands where life depended sometimes on tact and sometimes on military strategy. He appraised Hugo shrewdly before he spoke.

"What can I do for you, Mr. Danner?"

Hugo came directly to the point. "I should like to join your Yucatan expedition."

Professor Hardin smiled. "I'm sorry. We're full up."
