We stood in complete dismay—I did, at any rate—for about as long as it takes to peel a potato. There could be no doubt in which direction the van had moved, for the track of the wheels was plain. It had gone farther up the lane toward the quarry. In the earth, which was still soggy, were a number of footprints.  
"By the bones of Polycarp!" exclaimed the Professor, "those hoboes have stolen the van. I guess they think it'll make a fine Pullman sleeper for them. If I'd realized there was more than one of them I'd have hung around closer. They need a lesson."
 
Good Lord! I thought, here's Don Quixote about to wade into another fight.
 
"Hadn't we better go back and get Mr. Pratt?" I asked.
 
This was obviously the wrong thing to say. It put the fiery little man all the more on his mettle. His beard bristled. "Nothing of the sort!" he said. "Those fellows are cowards and vagabonds anyway. They can't be far off; you haven't been away more than an hour, have you? If they've done anything to Bock, by the bones of Chaucer, I'll harry them. I thought I heard him bark."
 
He hurried up the lane, and I followed in a panicky frame of mind. The track wound along a hillside, between a high bank and a forest of birch trees. I think the distance can't have been more than a quarter of a mile. Anyway, in a very few minutes the road made a sharp twist to the right and we found ourselves looking down into the quarry, over a sheer rocky drop of a hundred feet at least. Below, drawn over to one side of the wall of rock, stood Parnassus. Peg was between the shafts. Bock was nowhere to be seen. Sitting by the van were three disreputable looking men. The smoke of a cooking fire rose into the air; evidently they were making free with my little larder.
 
"Keep back," said the Professor softly. "Don't let them see us." He flattened himself in the grass and crawled to the edge of the cliff. I did the same, and we lay there, invisible from below, but quite able to see everything in the quarry. The three tramps were evidently enjoying an excellent breakfast.
 
"This place is a regular hang-out for these fellows," Mifflin whispered. "I've seen hoboes about here every year. They go into winter quarters about the end of October, usually. There's an old blasted-out section of this quarry that makes a sheltered dormitory for them, and as the place isn't worked any more they're not disturbed here so long as they don't make mischief in the neighbourhood. We'll give them...."
 
"Hands up!" said a rough voice behind us. I looked round. There was a fat, red-faced villainous-looking creature covering us with a shiny revolver. It was an awkward situation. Both the Professor and I were lying full length on the ground. We were quite helpless.
 
"Get up!" said the tramp in a husky, nasty voice. "I guess youse thought we wasn't covering our trail? Well, we'll have to tie you up, I reckon, while we get away with this Crystal Pallis of yourn."
 
I scrambled to my feet, but to my surprise the Professor continued to lie at full length.
 
"Get up, deacon!" said the tramp again. "Get up on them graceful limbs, if you please."
 
I guess he thought himself safe from attack by a woman. At any rate, he bent over as if to grab Mifflin by the neck. I saw my chance and jumped on him from behind. I am heavy, as I have said, and he sprawled on the ground. My doubts as to the pistol being loaded were promptly dissolved, for it went off like a cannon. Nobody was in front of it, however, and Mifflin was on his feet like a flash. He had the ruffian by the throat and kicked the weapon out of his hand. I ran to seize it.
 
"You son of Satan!" said the valiant Redbeard. "Thought you could bully us, did you? Miss McGill, you were as quick as Joan of Arc. Hand me the pistol, please."
 
I gave it to him, and he shoved it under the hobo's nose.
 
"Now," he said, "take off that rag around your neck."
 
The rag was an old red handkerchief, inconceivably soiled. The tramp removed it, grumbling and whining. Mifflin gave me the pistol to hold while he tied our prisoner's wrists together. In the meantime we heard a shout from the quarry. The three vagabonds were gazing up in great excitement.
 
"You tell those fashion plates down there," said Mifflin, as he knotted the tramp's hands together, "that if they make any fight I'll shoot them like crows." His voice was cold and savage and he seemed quite master of the situation, but I must confess I wondered how we could handle four of them.
 
The greasy ruffian shouted down to his pals in the quarry, but I did not hear what he said, as just then the Professor asked me to keep our captive covered while he got a stick. I stood with the pistol pointed at his head while Mifflin ran back into the birchwood to cut a cudgel.
 
The tramp's face became the colour of the under side of a fried egg as he looked into the muzzle of his own gun.
 
"Say, lady," he pleaded, "that gun goes off awful easy, point her somewhere else or you'll croak me by mistake."
 
I thought a good scare wouldn't do him any harm and kept the barrel steadily on him.
 
The rascals down below seemed debating what to do. I don't know whether they were armed or not; but probably they imagined that there were more than two of us. At all events, by the time Mifflin came back with a stout birch staff they were hustling out of the quarry on the lower side. The Professor swore, and looked as if he would gladly give chase, but he refrained.
 
"Here, you," he said in crisp tones to the tramp, "march on ahead of us, down to the quarry."
 
The fat ruffian shambled awkwardly down the trail. We had to make quite a detour to get into the quarry, and by the time we reached there the other three tramps had got clean away. I was not sorry, to tell the truth. I thought the Professor had had enough scrapping for one twenty-four hours.
 
Peg whinneyed loudly as she saw us coming, but Bock was not in sight.
 
"What have you done with the dog, you swine?" said Mifflin. "If you've hurt him I'll make you pay with your own hide."
 
Our prisoner was completely cowed. "No, boss, we ain't hurt the dog," he fawned. "We tied him up so he couldn't bark, that's all. He's in the 'bus." And sure enough, by this time we could hear smothered yelping and whining from Parnassus.
 
I hurried to open the door, and there was Bock, his jaws tied together with a rope-end. He bounded out and made super-canine efforts to express his joy at seeing the Professor again. He paid very little attention to me.
 
"Well," said Mifflin, after freeing the dog's muzzle, and with difficulty restraining him from burying his teeth in the tramp's shin, "what shall we do with this heroic specimen of manhood? Shall we cart him over to the jail in Port Vigor, or shall we let him go?"
 
The tramp burst into a whining appeal that was almost funny, it was so abject. The Professor cut it short.
 
"I ought to pack you into quod," he said. "Are you the Phoebus Apollo I scuffled with down the lane last night? Was it you skulking around this wagon then?"
 
"No, boss, that was Splitlip Sam, honest to Gawd it was. He come back, boss; said he'd been fightin' with a cat-o'-mountain! Say, boss, you sure hit him hard. One of his lamps is a pudding! Boss, I'll swear I ain't had nothin' to do with it."
 
"I don't like your society," said the Professor, "and I'm going to turn you loose. I'm going to count ten, and if you're not out of this quarry by then, I'll shoot. And if I see you again I'll skin you alive. Now get out!"
 
He cut the knotted handkerchief in two. The hobo needed no urging. He spun on his heel and fled like a rabbit. The Professor watched him go, and as the fat, ungainly figure burst through a hedge and disappeared he fired the revolver into the air to frighten him still more. Then he tossed the weapon into the pool near by.
 
"Well, Miss McGill," he said with a chuckle, "if you like to undertake breakfast, I'll fix up Peg." And he drew the horse-shoe from his pocket once more.
 
A brief inspection of Parnassus satisfied me that the thieves had not had time to do any real damage. They had got out most of the eatables and spread them on a flat rock in preparation for a feast; and they had tracked a good deal of mud into the van; but otherwise I could see nothing amiss. So while Mifflin busied himself with Peg's foot it was easy for me to get a meal under way. I found a gush of clean water trickling down the face of the rock. There were still some eggs and bread and cheese in the little cupboard, and an unopened tin of condensed milk. I gave Peg her nose bag of oats, and fed Bock, who was frisking about in high spirits. By that time the shoeing was ............
