"By Jove! The ammunition house is blazing!" cried Paul aghast. "If that goes up----" "It's far enough removed from the main buildings," cried Dick, as he began hurriedly to dress, "but it may damage the Sacred Pig. Besides, there are some valuable guns in there--and Paul--I forgot--Grit is in there! Come on!" and Dick raced from the room, half attired as he was. CHAPTER XIII THE RESCUE OF DUTTON "What do you mean? Grit in there--in the ammunition house?" cried Paul, hurrying after his chum. He wondered whether he had understood Dick rightly. "Yes, he's there," came the reply, and the young millionaire never turned around as he sped down the corridor that was rapidly filling with half-dressed cadets who had been aroused by the cries of the janitors. "They're repairing the stable where I keep him nights, and as it was unlocked I put Grit in the powder house so no one would steal him. Now it's on fire!" "We'll get him!" cried Paul. "Come on, fellows, Dick's dog is in there!" The flames were now more plainly visible, and they were gaining rapidly. Two of the janitors, one of whom was Toots, had pails of water and were dashing the fluid on the fire, while others were unreeling a hose. The ammunition house was a large one, made in the main of concrete, but there was built on it a small, wooden shed under which some empty packing boxes and cases were stored, and where some garden tools were kept. It was this shed which had caught fire, and unless it was quickly put out the flames might communicate to the wooden door of the powder house proper. There could be but one result then--an explosion. Everyone realized this as he rushed on to fight the fire. Some of the professors were now up and were issuing orders, but there was so much excitement that no one paid much attention to them. "Is there a good water pressure?" panted Paul. "I don't know," answered Dick, as he ran on. "There was the other day when we had fire drill, but maybe just when we want it there won't be any." "Hurry! Hurry!" shouted Toots, as he and the others dashed pail after pail of water on the fire. "Use the hose! Turn on the water!" cried Ray Dutton, who was just ahead of Dick. "Why don't you turn on the pressure?" "Guess they don't know how to do it," answered the young millionaire. "One of those men is a new hand. Come on, boys, I can't see Grit burned to death!" "He's howling now," cried Paul. Indeed the frightened yelping of the imprisoned animal could be heard above the roar and crackle of the flames, and Dick increased his speed. "I'm coming, Grit! I'm coming!" he shouted, but it is doubtful if the dog heard him. The burning shed was in front of the only door to the ammunition house, and the fire must first be extinguished before the portal could be reached. To go through the flames now was out of the question. "Keep back, boys! Keep back!" cried Major Webster. "There may be an explosion any moment. Keep back!"
