His opponent came on. He had learned from the rashness of his partner, for after putting up his hands, like a professional pugilist, he began feinting and circling about Alvin, in the search for an inviting opening. The latter did not forget the instruction he had received from Professor Donovan and stood on his guard, equally vigilant for an advantage.

The elder had made a complete circle about Alvin, who turned as on a pivot to meet his attack, and was just quick enough to parry the vicious blow launched at him, but not quick enough to counter effectively. The next instant the fist of the taller fellow came in contact with the chest of Alvin, who was driven back several paces. His foe attempted to follow it up, but was staggered by a facer delivered straight and true. Then our young friend in turn pressed the other, who, bewildered by the rapidity and fierceness of the assault, made a rush to clinch.

Nothing could have suited Alvin better and he met the effort with a storm of furious blows. The chief one was aimed at the chin, and had it landed the result would have been a knockout, but it was a trifle short. Determined not to be denied, Alvin pressed on with all the power at his command. "Keep cool and strike straight," was the motto of his instructor at the gymnasium, and though he was enraged he heeded the wise advice.

Nearly a score of blows were exchanged with such rapidity that a spectator could not have kept track of them, and then Alvin "got there." The thud was followed by an almost complete somersault of the victim. The master was prompted to push his success by attacking his enemy before he could rise, but another law flashed upon Alvin. "Never strike a man when he is down," a chivalrous policy when the rules of the game govern both contestants. It was doubtful whether Alvin would have received similar consideration had the situation been reversed, but he could not feel sure of that until the proof was given. He therefore calmly waited for the other to rise, when he would be upon him like a tiger.

A minute or two passed before the fallen one recovered enough to begin climbing to his feet. He could have risen sooner, but deceived his conqueror by feigning weakness and fumbled aimlessly about as if too groggy to get his bearings. But he was helping in a treacherous trick.

As Alvin stood, his back was toward the first miscreant, who recovered from his stupor while his companion still lay on the ground. Our young friend gave no thought to the one, whom he believed to be out of the affair altogether.

The same young man, however, gave quick thought to him. Bounding to his feet he sneaked up unseen and struck a blow that drove Alvin forward so violently that he had to make a leap over the second assailant to avoid falling upon him. It was a wonder that he was not struck down senseless. As it was, he was partially stunned, but rallied in a flash.

Now it would have been sensible and no disgrace to the heroic lad, when he found himself confronted by two muscular and enraged youths, to dash at full speed for home. But he did nothing of the kind.

"Come on, both of you!" he called out. "I'm not afraid and you haven't got me yet!"

It would be a pleasure to record that our young friend defeated the couple, but such a triumph in the nature of things was impossible. Either of them would have given him all he could do, and the two united were sure to overcome him. With his stubborn resolve to have it out with them he must have suffered but for an unexpected turn of events.
