was the spring of the trap. A light touch upon it was sufficient to disconnect a heavy stone from a barrel perched overhead and nicely balanced. The disconnecting of the stone permitted the barrel to turn over and spill its contents on the one beneath who touched the slat.
The boys examined the arrangement with keen appreciation. Luckily for them, the barrel was overturned, or they too would have received a ducking, for Joe, who was in advance, had blundered against the slat.
"I wonder if this is Simpson's back yard?" he queried softly.
"It must be," Fred concluded, "or else the back yard of some member of his gang."
Charley put his hands warningly on both their arms.
"Hist! What 's that?" he whispered.
They crouched down on the ground. Not far away was the sound of some one moving about. Then they heard a noise of falling water, as from a faucet into a bucket. This was followed by steps boldly approaching. They crouched lower, breathless with apprehension.
A dark form passed by within arm's reach and mounted on a box to the fence. It was Brick himself, resetting the trap. They heard him arrange the slat and stone, then right the barrel and empty into it a couple of buckets of water. As he came down from the box to go after more water, Joe sprang upon him, tripped him up, and held him to the ground.
"Don't make any noise," he said. "I want you to listen to me."
"Oh, it 's you, is it?" Simpson replied, with such obvious relief in his voice as to make them feel relieved also. "Wot d' ye want here?"
"We want to get out of here," Joe said, "and the shortest way 's the best. There 's three of us, and you 're only one—"
"That 's all right, that 's all right," the gang-leader interrupted. "I 'd just as soon show you the way out as not. I ain't got nothin' 'gainst you. Come on an' follow me, an' don't step to the side, an' I 'll have you out in no time."
Several minutes later they dropped from the top of a high fence into a dark alley.
"Follow this to the street," Simpson directed; "turn to the right two blocks, turn to the right again for three, an' yer on Union. Tra-la-loo."
They said good-by, and as they started down the alley received the following advice:
"Nex' time you bring kites along, you 'd best leave 'em to home."
Chapter V.
Home Again
Following Brick Simpson's directions, they came into Union Street, and without further mishap gained the Hill. From the brow they looked down into the Pit, whence arose that steady, indefinable hum which comes from crowded human places.
"I 'll never go down there again, not as long as I live," Fred said with a great deal of savagery in his voice. "I wonder what became of the fireman."
"We 're lucky to get back with whole skins," Joe cheered them philosophically.
"I guess we left our share, and you more than yours," laughed Charley.
"Yes," Joe answered. "And I 've got more trouble to face when I get home. Good night, fellows."
As he expected, the door on the side porch was locked, and he went around to the dining-room and entered like a burglar through a window. As he crossed the wide hall, walking softly toward the stairs, his father came out of the library. The surprise was mutual, and each halted aghast.
Joe felt a hysterical desire to laugh, for he thought that he knew precisely how he looked. In reality he looked far worse than he imagined. What Mr. Bronson saw was a boy with hat and coat covered with dirt, his whole face smeared with the stains of conflict, and, in particular, a badly swollen nose, a bruised eyebrow, a cut and swollen lip, a scratched cheek, knuckles still bleeding, and a shirt torn open from throat to waist.
"What does this mean, sir?" Mr. Bronson finally managed to articulate.
Joe stood speechless. How could he tell, in one brief sentence, all the whole night's happenings?—for all that must be included in the explanation of what his luckless disarray meant.
"Have you lost your tongue?" Mr. Bronson demanded with an appearance of impatience.
"I 've—I 've—"
"Yes, yes," his father encouraged.
"I 've—well, I 've been down in the Pit," Joe succeeded in blurting out.
"I must confess that you look like it—very much like it indeed." Mr. Bronson spoke severely, but if ever by great effort he conquered a smile, that was the time. "I presume," he went on, "that you do not refer to the abiding-place of sinners, but rather to some definite locality in San Francisco. Am I right?"
Joe swept his arm in a descending gesture toward Union Street, and said: "Down there, sir."
"And who gave it that name?"
"I did," Joe answered, as though confessing to a specified crime.
"It 's most appropriate, I 'm sure, and denotes imagination. It could n't really be bettered. You must do well at school, sir, with your English."
This did not increase Joe's happiness, for English was the only study of which he did not have to feel ashamed.
And, while he stood thus a silent picture of misery and disgrace, Mr. Bronson looked upon him through the eyes of his own boyhood with an understanding which Joe could not have believed possible.
"However, what you need just now is not a discourse, but a bath and court-plaster and witch-hazel and cold-water bandages," Mr. Bronson said; "so to bed with you. You 'll need all the sleep you can get, and you 'll feel stiff and sore to-morrow morning, I promise you."
The clock struck one as Joe pulled the bedclothes around him; and the next he knew he was being worried by a soft, insistent rapping, which seemed to continue through several centuries, until at last, unable to endure it longer, he opened his eyes and sat up.
The day was streaming in through the window—bright and sunshiny day. He stretched his arms to yawn; but a shooting pain darted through all the muscles, and his arms came down more rapidly than they had gone up. He looked at them with a bewildered stare, till suddenly the events of the night rushed in upon him, and he groaned.
The rapping still persisted, and he cried: "Yes, I hear. What time is it?"
"Eight o'clock," Bessie's voice came to him through the door. "Eight o'clock, and you 'll have to hurry if you don't want to be late for school."
"Goodness!" He sprang out of bed precipitately, groaned with the pain from all his stiff muscles, and collapsed slowly and carefully on a chair. "Why did n't you call me sooner?" he growled.
"Father said to let you sleep."
Joe groaned again, in another fashion Then his history-book caught his eye, and he groaned yet again and in still another fashion.
"All right," he called. "Go on. I 'll be down in a jiffy."
He did come down in fairly brief order; but if Bessie had watched him descend the stairs she would have been astounded at the remarkable caution he observed and at the twinges of pain that every now and then contorted his face. As it was, when she came upon him in the dining-room she uttered a frightened cry and ran over to him.
"What 's the matter, Joe?" she asked tremulously. "What has happened?"
"Nothing," he grunted, putting sugar on his porridge.
"But surely—" she began.
"Please don't bother me," he interrupted. "I 'm late, and I want to eat my breakfast."
And just then Mrs. Bronson caught Bessie's eye, and that young lady, still mystified, made haste to withdraw herself.
