Steve examined the report carefully. He had done a very shrewd thing. He had held the keeper of the dynamite stores responsible for a complete list of all the sticks of dynamite given out to the miners each day, and then had visited the drifts to find out how many charges had been fired and how many sticks had been used. As dynamite is never issued, except for immediate use, there could be none left over after the day's work was done. By the time the holes are drilled a messenger is on hand with just enough sticks of the deadly stuff to fill the holes. After checking up, the young inspectors found that twelve sticks of the explosive were unaccounted for. They had been drawn from the stores, but not used. "We are beginning to get somewhere, old chap," Steve said, nodding to his companion. "That means that someone--some unauthorized person--has drawn some dynamite from the stores, does it not?" questioned Jarvis. "That is the way I figure it out. It may mean nothing, so far as our case is concerned, and it may mean much." The boys remained in the mine as usual until the shift went up at six o'clock. At the appointed hour, eight o'clock, they made their way back to the shaft, but instead of going down on the cage they slipped into the ladder hole and began their descent in this way. It was decided that Bob should begin at the upper levels and work down, while Steve was to make his way to the bottom of the shaft and work up. When they met they would compare notes. Each had a list of every man who had business in the mine that night, so that they could find out, by asking a man's name, whether or not he had a right to be there. Steve had gone directly to the bottom and covered every level up to that where the pump station was located, about half way up the shaft. He started along this level, keeping out of sight as much as possible, which had been the policy of each lad, as agreed upon beforehand. Steve had not proceeded far when he discovered that someone was walking along the level ahead of him. At first he thought it was Jarvis, as the man's hat held no light, and Bob should be somewhere about at that time. Steve quickened his steps, intending to overhaul the man and speak to him. All at once the fellow turned abruptly off from the main level, entering a drift that ran to the south, but as he passed under the electric light at the turn Steve Rush made a discovery. The man was heavily bearded and Steve recognized him instantly. "It's the man Klink," he muttered. "What is he doing in that drift at this time of night?" Consulting his list, the boy saw that Klink did not belong to the night shift of that particular night. He moved up, intending to follow Klink into the drift, when the man suddenly emerged. Steve flattened himself on the ground and waited, while the other glanced cautiously up and down the level. Satisfying himself that no one was about, Klink turned and walked on.
