Immediately across could be seen the Senior mascot, a very disreputable Billy goat, "bearded like the pard" and with only one horn left. When Mud got a glimpse at his rival, nothing but a distinct sense of duty restrained him from an immediate attack. When "William" was led, struggling violently, around the field just before the game started, Mud ran out on the long sleeve in a vain effort to reach his very disreputable-looking enemy, but even then could not be tempted to leave his precious charge.

He became very much excited when the men took their places for the "kick-off," and barked furiously at every "down" during the first "half." It was a hard old game, too, and one remembered long after. Class games are often more severe than contests with outside teams, for class rivalry is very strong, and there are not the same pains taken to restrain roughness. The Seniors kept bucking the line fiercely, and Shack at "centre" had all the fun he wanted holding his ground against repeated assaults. He was well backed up, however, by Marlowe on one side and Terry on the other, and the "half" ended with the score six to nothing in favor of the Sophs.

It was a proud moment indeed for little Mud when he was led around the field with the big ribbon on his neck, and so important did he feel that he did not even notice old "Billy," although he trotted close by him.

The Seniors started in with the same tactics when the whistle blew again, although they had not been at all successful. Not a "round the end" play did they make, and they were at last rewarded for their perseverance by knocking the wind out of Marlowe so completely that he was obliged to retire.

The man that took his place was sandy enough, and well up in the game; but he was too light to keep his feet on the soft ground, and it did not take the Seniors long to discover that a plunge at "right guard" was good for from two to five yards every time. Old Shack gave all the assistance he could, but he was fairly well employed in attending to his opposite, and the result was that the ball was worked slowly but steadily up the field with every prospect of being carried over the Sophs' line.

Nothing but the call of time could save them, and they lined up more and more slowly, struggling desperately and praying for the sound of the whistle. Down the lines the spectators followed, cheering hoarsely, and cutting up the soft turf like a huge drove of cattle. There were but two more minutes of play and a scant five yards to make. Old Shack had a cut over his right eye, and a little stream of blood trickled down his mud-stained cheek. He was steaming like a "yoke of oxen," and his canvas jacket was drenched with sweat, one stocking was down over his shoe, and a sleeve of his jersey was gone, showing the huge arm with its corded muscles.

He knew well enough that the "touchdown" must come unless something was done, but no good chance did he get until the ball was inside the five-yard line. "Four-twelve-twenty" called out the "quarter back," and the big "senior centre," crouching low against Shack's strong shoulder, snapped the ball back just as he had done a hundred times before that day. He got a bit too low, in fact, for Shack gave him a jerk, and before the little "quarter" could get the ball out of his hands Shack's big paw was on him, rolling him over like a kitten, and before he knew what had happened he had lost the ball, and Shack had it snugly tucked under his arm.

How the Sophs cheered, and when a moment later the whistle blew they would have shouldered Shack had he not made it impossible by lying flat on the muddy ground.

During these last five minutes Mud had been deserted and well-nigh forgotten, mascot though he was. The crowd had surged up the field where the fierce struggle was going on, and the little fellow was left all alone, with nothing to occupy him but his own thoughts. He could look across to "Billy" on the other side, tied to a post, and alternately barked at him and whined for the friends who had left him.

Mud had no chains but those of duty, yet for him they were sufficient. He would very much have liked to follow the crowd, or better still to have had his own little game of football with "Billy" across the way, with neither an umpire nor a referee to keep account of distance or prevent rough play; but here was Shack's precious sweater, and here he was bound to stay.
