"Hostilities have broken out between the two doctors," said Tom. "They were quarreling in the hall when I entered, and left the house shaking their fists in each other's faces." "What about?" inquired Toney. "I was unable to ascertain," said Tom. "Well, never mind," said the Professor. "Who shall decide when doctors disagree? Toney, let us hear the concluding portion of your manuscript. But, by Jove! what's that?" A loud noise was heard in the street; men shouting and boys hurrahing. Tom Seddon snatched up his hat, and, followed by Toney and the Professor, ran from the room. CHAPTER XXI. "Hurrah for Bull!" shouted a boy, as Tom reached the pavement in front of the hotel. "Bully for Bear! Pitch in! Hit him again! He called you another liar!" yelled a ragged urchin on the opposite side of the street. "Who are those belligerent gentlemen?" asked the Professor. "The very two doctors I saw shaking their fists in each other's faces at Colonel Hazlewood's door," said Tom Seddon. "I thought there would soon be active hostilities between them." "Good for Bull!" cried an urchin. "Wade in, Bear!" shouted another. "I bet on Bull!" said a third. "Bear's the man for my money!" yelled a fourth. "Which is Bull?" asked the Professor. "The red-faced man with spectacles on his nose, who is standing up in the buggy without a top, and is menacing his antagonist with the butt end of his whip," said Tom Seddon. "And Bear is the short fat man on horseback, brandishing his cane?" said Toney. "The same," said Seddon. "Right cut against cavalry!" shouted a soldier on the pavement, as Bull aimed a blow at Bear with his whip. "By jabers! that's the prod!" cried an Irishman, as Bear thrust the end of his cane in his adversary's face. The horse attached to the buggy now moved on a few paces and halted. Bear sat still on his horse, fiercely gazing at his antagonist. "At him again!" cried a boy. "Don't be afraid! Show the blood of your mother!" yelled a second urchin. "Charge, Chester, charge!" shouted a third. Bear furiously spurred his horse and rushed up to the buggy. A blow from Bull's whip knocked off his hat, and his bald head shone in the sun. At the same time a thrust from Bear's cane deprived Bull of his spectacles. "Hurrah for Bear! He has knocked out Bull's eyes!" shouted a boy. Bull seized Bear's cane and pulled it from his hands. Bear reached out and grasped Bull by the top of his head. Bull's wig came off. "Hurrah! hurrah! he has scalped him!" shouted a boy. Bull was infuriated. He grappled Bear by a tuft of hair that grew on the side of his head. Bear's horse started back and the rider fell over his neck into the buggy. Then both belligerents commenced furiously fighting with their fists. "I command the peace! I command the peace!" cried a portly gentleman on the pavement. "They are at close quarters," said a soldier. "It is too late to command the peace."
