Dick sprang to the relief of Buttons, who was at his last extremity. But the Doctor was before him, as cool as ever. He grasped one fellow by the throat--a favorite trick of the Doctor's, in which his anatomical knowledge came very finely into play: "Off!" rang the Doctor's voice. The fellow gasped a curse. The next instant a roar burst through the air, and the wretch fell heavily forward, shot through the head, while his brains were splattered over the face of Buttons. The Doctor with a blow of his fist sent the other fellow reeling over. Buttons sprang up gasping. The Italians were falling back. He called to the Senator. That man of might came up. Thank God they were all alive! Bruised, and wounded, and panting--but alive. The scowling bandits drew off, leaving seven of their number on the road _hors de combat_. Some of the retreating ones had been badly treated, and limped and staggered. The Club proceeded to load their rifles. The Doctor stepped forward. Deliberately aiming he fired his revolver five times in rapid succession. Before he had time to load again the bandits had darted into the woods. "Every one of those bullets _hit_," said the Doctor with unusual emphasis. "We must get under cover at once," said Dick. "They'll be back shortly with others!" "Then we must fortify our position," said the Senator, "and wait for relief. As we were, though, it was lucky they tried a hand-to-hand fight first. This hill shelters us on one side. There are so many trees that they can't roll stones down, nor can they shoot us. We'll fix a barricade in front with our baggage. We'll have to fight behind a barricade this time; though, by the Eternal! I wish it were hand-to-hand again, for I don't remember of ever having had such a glorious time in all my born days!" The Senator passed his hand over his gory brow, and walked to the coach. "Where's Pietro?" "Pietro! _Pietro_!" No answer. "PI-E-TRO!" Still no answer. "Pietro!" cried Dick, "if you don't come here I'll blow your--" "Oh! is it you, Signori?" exclaimed Pietro's voice; and that worthy appeared among the trees a little way up the hill. He was deadly pale, and trembled so much that he could scarcely speak. "Look here!" cried Buttons; "we are going to barricade ourselves." "Barricade!" "We can not carry our baggage away, and we are not going to leave it behind. We expect to have another battle." Pietro's face grew livid. "You can stay and help us if you wish." Pietro's teeth chattered. "Or you can help us far more, by running to the nearest town and letting the authorities know." "Oh, Signore, trust me! I go." "Make haste, then, or you may find us all murdered, and then how will you get your fares--eh?" "I go--I go; I will run all the way!" "Won't you take a gun to defend yourself with?" "Oh no!" cried Pietro, with horror. "No, no!" In a few minutes he had vanished among the thick woods. [Illustration: Pietro.]
