As the stream of boys poured out of the building, the howling of the bulldog nearby became more furious than ever. It immediately attracted the attention of the observant Frank. "Hark!" he said, holding up his hand to indicate that silence would be necessary if they hoped to succeed in accomplishing anything worth while. "What is it?" demanded Lanky, eagerly; "do you see Bones, or did you hear him shout for help?" "Neither. I was thinking of his dog," was the reply. "What of old Kaiser, Frank? How does he come in this game?" asked Buster. "You can tell from the way he's acting that Bones has never been near him. More than that, I believe the smart dog knows that something has happened to his master, for he's just wild to get free!" declared Frank. "Sure as you live! Just listen to him growl and bark. I never heard a bulldog do that before!" cried Ralph. "Oh, Kaiser is only a half-breed mongrel, but looks like a full-blooded bull. But an idea just occurred to me, fellows." "Then let's have it, Frank. We're short of ideas at present, just as we are of a bully good football player needed in to-morrow's game. What is it?" asked Molly Manners, unduly excited by these strange occurrences. "Perhaps the dog might lead us to where Bones is!" said Frank. "Say, now, that's just a crackerjack suggestion. Of course, he will, if someone could only hold him in by his leash!" exclaimed Lanky, with the light of anticipation shining on his face. "Come on, let's try it!" shouted another fellow. "But who's going to unfasten Kaiser, and hold him?" asked Frank, always practical, even at such moments as this. "Here's Buster, he knows the dog better than anyone else," said Jack Eastwick, pushing the fat boy forward. "Oh, yes, I've had an intimate acquaintance with him. He's tasted of me three different times," declared the unwilling candidate for honors. "Still, he knows you?" said Jack, in a wheedling voice. "Sure, and I think he likes me, which shows Kaiser has good taste. But I'm willing to be the victim, if you'll all promise to see that my remains are gathered up and given a fitting burial. Everyone who likes a good show, this way, now. The only and original dog-tamer is about to give an exhibition of how not to do it." Kaiser was acting in a very ugly way, as they approached the spot where he had been tied up by his master, upon reaching the hall. He jumped up and out in a furious manner, always in the one direction, Frank noticed. "You see, fellows, he pays no attention to us. His growls are for someone else, and he is trying to break loose, in order that he may chase after them. I shouldn't be surprised if we had some success, after all. Do it, Buster. The whole world is looking to you now as the hero of the occasion." Buster gave Frank a plaintive look, as he bent down, and began to speak soothingly to the furious dog. "Listen to his soft soap talk, would you!" "Buster knows how to lay it on; he's kissed the blarney stone!"
