ATTACKED BY ENEMIES, AND LOST IN THE MINE

Although Derrick was terribly frightened by the explosion, and considerably bruised by the shower of rocks and coal that followed it, the car had so protected him that he was not seriously hurt. Had his mule started forward the heavily loaded car must have run over and killed him. Fortunately Harry was too experienced a miner to allow such a trifling thing as a blast to disturb his equanimity, especially as the two false starts already made had placed him at some little distance from it. To be sure, he had shaken his head at the flying bits of coal, and had even kicked out viciously at one large piece that fell near his heels. The iron-shod hoof had shattered the big lump, and sent its fragments flying over Derrick, but in the darkness and confusion the boy thought it was only part of the explosion, and was thankful that matters were no worse.

As Derrick cleared himself from the mass of rubbish that had fallen on him, and staggered to his feet, he was nearly suffocated by the dense clouds of powder-smoke from the blast. He was also in utter darkness, both his lamp and that of Harry Mule having been blown out. In his inexperience he had not thought to provide matches before entering the mine, and now he found himself in a darkness more dense than any he had ever dreamed of, without any means of procuring a light. His heart grew heavy within him as he realized his situation, for he had no idea whether the miner who had played so cruel and dangerous a trick upon him would return or not.

An impatient movement on the part of Harry Mule suggested a plan to him. Casting off the chain by which the mule was attached to the car, and holding the end in his hand, he said, "Go on, Harry, and take me out of this place." At this command the intelligent animal started off towards the junction as unhesitatingly as though surrounded by brightest daylight, and Derrick followed.

They had not gone far before they met Monk Tooley, leisurely returning to the scene of his labors.

"Hello! Mr. Mule-driver," he shouted, "what are you a-doing here in de dark, an' how do yer like mining far as ye've got? Been studying de effect of blarsts, and a-testing of 'em by pussunal experience?"

Derrick felt a great lump rising in his throat, and bitter thoughts and words crowded each other closely in his mind. He knew, however, that the man before him was as greatly his superior in wordy strife as in bodily strength, so he simply said,

"The next time you try to kill me you'd better take some surer means of doing it."

"Kill you! Who says I wanted to kill you?" demanded the miner, fiercely, as he stopped and glared at the boy. "Didn't I holler to ye to run? Didn't I give yer fair warnin' that I was shootin' a blarst? Didn't I? Course I did and yer didn't pay no 'tention to it. Oh no, sonny! 'twon't do. Ye mustn't talk 'bout killin' down in dese workin's, cause 'twon't be 'lowed. Come back now, an' git my wagon. Here's a light for yer, but don't let me hear no more talk 'bout killin', or ye may have a chance to wish yer was dead long before yer really is."

Derrick made no reply to this, but turning Harry Mule about, they went back after the car. He was convinced that this man was his bitter and unscrupulous enemy, and made up his mind that he must be constantly on his guard against him. He did not tell anybody of this startling incident of his first day's experience in the mine for a long time afterwards; as, upon thinking it over, he realized that the peril, which he had so happily escaped might readily be charged to his own carelessness.
