Now, suddenly, Darrin seemed to change not only his tactics, but his whole personality. To his opponent Dave seemed suddenly transformed into a dancing demon. It was about the same old footwork, but it was aggressive now, instead of being defensive. First, Dave landed a light tap on the already suffering nose. A few seconds later he landed on the point of Pen's chin, though not hard enough to send his man down. Then a rather light blow on the jaw, just under Pen's right ear again. The larger midshipman was now thoroughly alarmed. He feared that Darrin could do whatever he willed, and shivered with wonder as to when the knockout blow would come. The truth was, Pennington was still putting up a better battle than he himself realized, and Darrin was not disposed to take any foolish chances through rushing the affair. Thus, the third round ended. By the time that they came up for the fourth round, after both men had undergone some vigorous handling by their respective seconds, Pennington was a good deal revived and far more confident. Dave's tactics were the same in the fourth round. Pennington didn't find time to develop much in the way of tactics for himself, save to defend himself. During the first minute no important blows were landed on either side. Then, suddenly, Dave darted in and under, and brought a right-arm hook against Pen's nose in a way that started that member to bleeding again, and with a steady flow. That jarred the larger midshipman. He plunged in, heavily and blindly, blocking one of Darrin's blows by wrapping both arms around him. "None of that, Mr. Pennington! Break away fast!" ordered Midshipman Remington quickly. Dave took a fair get away, not attempting to strike as the clinch was broken. But an instant later Dave came back, dancing all around his dazed opponent, landing on the short ribs, on the breast bone, under either ear and finally on the tip of the chin. Pen was sure that none of these blows had been delivered with the force that Darrin could have sent in. "Time!" shouted Midshipman Dawley. The principals retired to their corners, Pennington almost wholly afraid from the conviction that his antagonist was now merely playing with him to keep the interest going. So Pennington was still rather badly scared when the two came together for the fifth round. "Get lively, now, gentlemen, if you can," begged Referee Remington. "Finish this one way or the other, and let us get some of the benefits of our shore leave." Pen started by putting more steam behind every blow. Dave, who had used up so much of his wind by his brilliant footwork, began to find it harder to keep the upper hand. Twice, however, he managed to land body blows. He was trying to drive in a third when Pennington blocked, following this with a left-arm jab on Darrin's left jaw that sent the lighter man to the floor. Instantly Dawley began to count off the seconds. "--seven, eight, nine, te----"
