True, I might learn where this Master of the World hid himself. I might learn what no one had yet been able to discover, assuming always that he did not dispose of me at one time or another--and what I expected his "disposal" would be, is easily comprehended.

I knew the northeast end of Lake Erie well, having often visited that section of New York State which extends westward from Albany to Buffalo. Three years before, a police mission had led me to explore carefully the shores of the Niagara River, both above and below the cataract and its Suspension Bridge. I had visited the two principal islands between Buffalo and the little city of Niagara Falls, I had explored Navy Island and also Goat Island, which separates the American falls from those of the Canadian side.

Thus if an opportunity for flight presented itself, I should not find myself in an unknown district. But would this chance offer? And at heart, did I desire it, or would I seize upon it? What secrets still remained in this affair in which good fortune or was it evil fortune--had so closely entangled me!

On the other hand, I saw no real reason to suppose that there was any chance of my reaching the shores of the Niagara River. The "Terror" would surely not venture into this trap which had no exit. Probably she would not even go to the extremity of the lake.

Such were the thoughts that spun through my excited brain, while my eyes remained fixed upon the empty horizon.

And always one persistent question remained insolvable. Why had the captain written to me personally that threatening letter? Why had he spied upon me in Washington? What bond attached him to the Great Eyrie? There might indeed be subterranean canals which gave him passage to Lake Kirdall, but could he pierce the impenetrable fortress of the Eyrie? No! That was beyond him!

Toward four o'clock in the afternoon, reckoning by the speed of the "Terror" and her direction, I knew we must be approaching Buffalo; and indeed, its outlines began to show some fifteen miles ahead. During our passage, a few boats had been seen, but we had passed them at a long distance, a distance which our captain could easily keep as great as he pleased. Moreover, the "Terror" lay so low upon the water, that at even a mile away it would have been difficult to discover her.

Now, however, the hills encircling the end of Lake Erie, came within vision, beyond Buffalo, forming the sort of funnel by which Lake Erie pours its waters into the channel of the Niagara river. Some dunes rose on the right, groups of trees stood out here and there. In the distance, several freight steamers and fishing smacks appeared. The sky became spotted with trails of smoke, which were swept along by a light eastern breeze.

What was our captain thinking of in still heading toward the port of Buffalo! Did not prudence forbid him to venture further? At each moment, I expected that he would give a sweep of the helm and turn away toward the western shore of the lake. Or else, I thought, he would prepare to plunge beneath the surface. But this persistence in holding our bow toward Buffalo was impossible to understand!

At length the helmsman, whose eyes were watching the northeastern shore, made a sign to his companion. The latter, leaving the bow, went to the central hatchway, and descended into the engine room. Almost immediately the captain came on deck, and joining the helmsman, spoke with him in a low voice.

The latter, extending his hand toward Buffalo, pointed out two black spots, which showed five or six miles distant on the starboard side. The captain studied them attentively. Then shrugging his shoulders, he seated himself at the stern without altering the course of the "Terror."

A quarter of an hour later, I could see plainly that there were two smoke clouds at the point they had studied so carefully. Little by little the black spots beneath these became more defined. They were two long, low steamers, which, coming from the port of Buffalo, were approaching rapidly.
