The march was resumed after dinner and academy was reached in time for supper. The cadets were much pleased with their practice "hike," while the officers were complimented on the order they had maintained. "I guess the colonel would preach a different sort of a sermon if he knew about the corn," remarked Paul, as he and Dick started for their quarters. "Well, as long as he doesn't know, there's no harm done." "My, but I'm tired," announced Paul, as he undressed. "I'm glad we don't have any lessons to-morrow." "What do we have?" "Artillery drill. Have you forgotten?" "That's so. I had. I've got to ride one of the leading horses too. Guess there'll be plenty of excitement." "Shouldn't wonder. I'm on the gun-carriage, where I reckon I'll be shaken so my liver pin will fall out." "I'll try not to let it. There go taps. Douse the glim." The two cadets crawled into bed and were soon asleep. Artillery drill at the Kentfield academy was as near like the real article as possible. The guns were four-inch field pieces, each drawn by six horses, the two leaders being ridden by cadets, while seven men were on the gun itself, an arrangement somewhat different from that in the regular army. Real ammunition was used in practice, the pieces being directed at target placed against a hill of soft dirt, in which the balls buried themselves. The artillery practice began soon after morning inspection. The cadets had all been instructed in how to load, aim and fire the field pieces, and had also had practice in driving the artillery into place. For the first time, however, they were now to indulge in this under the critical eye of an officer from the regular army, who was visiting the academy. The first part of the drill consisted in firing at targets, before horses were hitched to the guns. The cadets did well at this, the different squads making good scores. Dick, who was detailed at the breech, had a chance to aim. He thought he sighted perfectly, but when it was fired the ball did not hit the target cleanly. It was the last shot in that particular part of the tactics, and it left Dick's squad with the lowest record. "That's all your fault, Hamilton!" cried Captain Dutton angrily. "Why didn't you aim that right? Then we'd have had a chance to make a good score." "I did aim it right, but the gun must have shifted. Maybe one of the wheels was on a small stone." "Nonsense. It's your stupidity. You've lost us a good mark." Dutton angrily slammed the breech-block shut. Dick gave a start, but stifled the cry of pain that he was ready to give utterance to, for one of his fingers was caught in the breech, and the blood spurted from it, as the angry captain closed the gun. "Open the breech! Quick!" cried Paul, who had seen what had happened. "What's that?" asked Dutton, who had turned aside.
