Several times they came to the edge of the little wood where I was hidden, and gathered sticks for a fire which they made upon the beach. The region is so uninhabited and the creek so hidden from the lake that they ran little danger of discovery. They seemed to know this."

"You would recognize them both again?"

"Perfectly. One was of middle size, vigorous, and quick of movement, heavily bearded. The other was smaller, but stocky and strong. Yesterday, as before, I left the wood about five o'clock and hurried back to Toledo. There I found a telegram from Mr. Ward, notifying me of your coming; and I awaited you at the station."

Summed up, then, the news amounted to this: For forty hours past a submarine, presumably the one we sought, had been hidden in Black Rock Creek, engaged in repairs. Probably these were absolutely necessary, and we should find the boat still there. As to how the "Terror" came to be in Lake Erie, Arthur Wells and I discussed that, and agreed that it was a very probable place for her. The last time she had been seen was on Lake Superior. From there to Lake Erie the machine could have come by the roads of Michigan, but since no one had remarked its passage and as both the police and the people were specially aroused and active in that portion of the country, it seemed more probable, that the "Terror" had come by water. There was a clear route through the chain of the Great Lakes and their rivers, by which in her character of a submarine she could easily proceed undiscovered.

And now, if the "Terror" had already left the creek, or if she escaped when we attempted to seize her, in what direction would she turn? In any case, there was little chance o following her. There were two torpedo-destroyers at the port of Buffalo, at the other extremity of Lake Erie. By treaty between the United States and Canada, there are no vessels of war whatever on the Great Lakes. These might, however, have been little launches belonging to the customs service. Before I left Washington Mr. Ward had informed me of their presence; and a telegram to their commanders would, if there were need, start them in pursuit of the "Terror." But despite their splendid speed, how could they vie with her! And if she plunged beneath the waters, they would be helpless. Moreover Arthur Wells averred that in case of a battle, the advantage would not be with the destroyers, despite their large crews, and many guns. Hence, if we did not succeed this night, the campaign would end in failure.

Arthur Wells knew Black Rock Creek thoroughly, having hunted there more than once. It was bordered in most places with sharp rocks against which the waters of the lake beat heavily. Its channel was some thirty feet deep, so that the "Terror" could take shelter either upon the surface or under water. In two or three places the steep banks gave way to sand beaches which led to little gorges reaching up toward the woods, two or three hundred feet.

It was seven in the evening when our carriage reached these woods. There was still daylight enough for us to see easily, even in the shade of the trees. To have crossed openly to the edge of the creek would have exposed us to the view of the men of the "Terror," if she were still there, and thus give her warning to escape.

"Had we better stop here?" I asked Wells, as our rig drew up to the edge of the woods.

"No, Mr. Strock," said he. "We had better leave the carriage deeper in the woods, where there will be no chance whatever of our being seen."

"Can the carriage drive under these trees?"

"It can," declared Wells. "I have already explored these woods thoroughly. Five or six hundred feet from here, there is a little clearing, where we will be completely hidden, and where our horses may find pasture. Then, as soon as it is dark, we will go down to the beach, at the edge of the rocks which shut in the mouth of the creek.
