The wire was held down close to the ground by frequent metal wickets, as Rob had figured might be the case, for that would have been his own method of concealing the wire, and could be easily accomplished by a second man who crept after the one allowing the wire to free itself from the big spool he carried.

Rob was not bothering himself about these details now. To get that wire cut in twain before the man handling the battery at the other end sent the electric current along that would discharge the mine—that was his one endeavor.

Tubby knew he was working to accomplish this end. He watched what was going on so close by, though Rob and Andy could only be seen indistinctly; but Tubby was able to easily supply through a lively imagination whatever was lacking.

Tubby turned his head and looked toward the span. In imagination he could see it give a sudden, terrible heave and go flying in many fragments toward the sky!

Just when it was beginning to get unbearable, so that Tubby was almost forced to shout out, the suspense ended. He knew from the chuckle that Andy could not for the life of him suppress, that the wire had yielded to the force Rob was applying, and no longer ran in a connected line from mine to battery!

As long as he lived Tubby would surely never, never forget the spasm of glorious feeling that shot through his whole mind and body when he realized this stupendous fact. When one has been straining might and main to accomplish a given thing, and at the last gasp victory comes into his hand, that is the time he feels like a world conqueror and would not change places with any king living. Tubby passed through this experience, even though his may not have been the hand to wield those magical little pliers with which the wire had been severed. However, the honor and glory was great enough to go all around, and every fellow who had anything to do with the deed ought to share in the result.

Rob, having cut the wire, hastened to wind one end about the nearest stout bush he could reach, choosing the base, so as to have it afford effectual resistance.

This was that portion of the broken wire which had connection with the battery; the other end he cared nothing about, since the mine had been rendered harmless. It was just as well that the plotters did not know in too big a hurry how their cunning scheme had been nipped in the bud. Time enough for that when the fellow finally pressed his battery key into service, only to find to his utter amazement and disgust that no roaring response followed his action.

“Well,” Tubby gloatingly told himself, “perhaps those chaps would be a surprised lot when they found out what a mess they had made of it, not only missing the destruction of the million-dollar munition train, but failing to even blow up the bridge itself as intended. There’s many a slip between the cup and the lip, they say. I guess it was a bad hour for your schemes, my boys, when Rob Blake put his foot in this affair. As usual, it promises to wind up in fresh glory for the Eagles.”

Tubby was not the only one who breathed more freely after the wire was cut. Rob and Andy, possibly also Zeb, felt like chuckling as the culminating stroke was given that put it out of the power of the men hidden in the bushes to carry out their dark designs.
