Dropping on his hands and knees he examined the floor carefully to see if any of the boards were loose, but all of them were securely fastened to the huge beams that made up the framework of the barn. The boards were very thick and any thought of escaping under the barn was out of the question. From there he went to the door, feeling carefully along the sides to see if any signs of weakness existed here, but once again he was disappointed. Like the rest of the barn the door and the frame had been strongly constructed and it did not even quiver under his hearty kicks.

“About the only thing I can do—if I can do it—is to kick a board off the side of the wall,” he decided.

With this thought in mind he raised his foot, but then a sound reached his ears, a sound that made his blood chill.

With a clarity and snap the call of assembly rang out on the morning air!

“Good night!” groaned Terry, the sweat breaking out on his forehead. “There goes the call to assemble! If I’m ever going to get out of here in time, now is the moment!”

With desperation Terry kicked stoutly at the wall boards, but with the first kick the bitter truth was forced upon him. The sides of the barn were as strongly composed as the rest of the building, and all the kicking in the world would not get him out of the room in which he was held prisoner. To further worry him certain sounds told him that the process of assembly was going forward rapidly.

Doors slammed, running footsteps sounded on the parade grounds, voices rang out as the assembling cadets gathered. The butt of a rifle cracked on the pavement, and the noise of stamping horses reached his ears. The cavalrymen, of which Jim Mercer was the chief, were leading out the spirited mounts, and the creaking of leather, the snorts of the horses, and the cries of the young soldiers, reached the ears of the unfortunate young cadet. Hoping to attract their attention he pounded and yelled at the top of his voice, but no response came back to him. They were making too much noise themselves to hear him.

Closer at hand there was a deeper rumble and Terry groaned in spirit. It was the members of his own division, the artillery, taking out the field guns that they were to take with them for the summer practice. He was the chief gunner on the sleek steel monster which he had named the “Gossip” and he knew that the others of his crew must be wondering where he was. Just as soon as the guns were in formation and the roll call sounded he would be officially marked absent from duty and held guilty of disobeying orders. As he heard the guns roll out of the barracks and heard the noise of the towing cables being connected he knew it was too late.

From the barracks to the parade ground there was a slight hill and the trucks began to pull the weapons up the grade. He heard them go up one by one and then something seemed to go wrong. There was a snap, a rumble and somebody cried out.

“Look out!” he heard Captain Rush bellow. “Number One gun is loose!”
