Ralph Gurney's Oil Speculation. Otis James

night was not as favorable for the scheme as it might have been, for the moon was nearly full, and objects could be distinguished almost as readily as at noonday, save when under the veil cast by the shadows.

      This moonlight, Bob thought, would not interfere with their plan, since from the back of the house to the forest was but a few yards, and unless Newcombe should station one of his men there, the building would screen them from view.

      In case they got safely away from the house, the light would aid them, both in their journey through the woods and in their work after they arrived at the well.

      For some time the boys enjoyed thoroughly the anticipation of fooling Mr. Newcombe, and they might have continued to do so until it would have been too late to accomplish the work, had not Bob reminded them that they had no time to lose.

      Then they made their preparations for the journey or flight, whichever it might be called. The long, tin cartridges were tied together securely, with wads of paper between to prevent them from rattling; the cans of nitro-glycerine were placed by the window, where they could be gotten at readily, and Bob produced a three-cornered piece of iron, about four feet long, which weighed twenty or thirty pounds.

      "It will be quite an addition to your load; but I fancy you will feel safer carrying it than you would one of the cans," he said to Ralph.

      "What is it?"

      And the tone in which the question was asked showed that the newcomer to the oil fields looked upon this carrying a useless piece of iron through the woods as very unnecessary work.

      "That's the go-devil," replied Bob; and then, as he saw that Ralph did not understand, he added: "It is to drop through the hole to explode the cartridges after they are placed in position."

      Still Ralph could not fully understand its importance; but he stationed himself by the window, resolved to carry the go-devil and the cartridges any distance, rather than take the chances of being obliged to burden himself with the dangerous oil which the others appeared to regard with so little fear.

      Everything was in readiness for the start, and Bob clambered up to the peep-hole that he might be sure the enemy were yet in their position, which was so favorable to the plans of the moonlighters.

      "They are all there except the one who drove away some time ago, and – here comes the other now. He had been for food, and they are pitching into it as if they were hungry. Now is our time to start. They will be at their supper for the next half hour, and by the end of that time we shall be ready to come back for a second load."

      Bob looked once more to the fastenings of the doors and windows to be certain that they could not be loosened by any one from the outside, and then he cautiously unbarred the window at the back of the house.

      Knowing that the detective and all his force were in front, he spent no time in looking around; but, leaping out, was soon busily engaged in taking out the cans of glycerine which Jim and Dick handed him.

      Less than ten minutes sufficed for this work, and then each member of the party was out of doors, Ralph with the cartridges over his shoulder and the go-devil under his arm, while the others carried a can of the dangerous liquid in each hand.

      It had been decided that George, being accustomed to traveling through the woods in straight lines by his work as engineer, should lead the party, as the one most likely to keep a direct course, and Ralph had decided that he would remain as far in the rear as possible; for, when he saw the boys swinging the terrible explosive around so carelessly, he felt that the further away one could get from that party the safer they were.

      George was not as much at his ease as he might have been, for he had not grown familiar with the explosive, as the others had, and he uttered many a word of caution when they came to those portions of the woods where the trees stood more thickly together.

      Their progress was necessarily slow, owing to the care they were obliged to use in walking; but before Mr. Newcombe and his friends had finished their supper, the moonlighters were at Mr. Hoxie's well, where they found their arrival had long been expected.

      Mr. Hoxie could understand, from the manner in which the moonlighters had come, that they had run some risk of detection in getting there, and when he learned that they were obliged to make a second trip for more glycerine, he offered either to accompany them or send some of his men with them, as they should prefer.

      Bob refused all these offers of assistance, however, for he believed that it was owing to Mr. Hoxie's incautious remarks that the detectives had paid them a visit, and he did not propose to run any more risks than were absolutely necessary.

      Since four of them could carry all the glycerine needed to make up the charge, and since Ralph had such a wholesome fear of the dangerous compound, Bob insisted that Ralph remain at the well, while the others paid a second visit to the hut in the forest, a proposition which Ralph eagerly accepted, for carrying nitro-glycerine through the woods in the night was a task he was not at all anxious to perform.

      The return through the woods was made in a very short time, the boys walking on at full speed until they were near the hut, when the utmost caution was used. By making quite a detour through the woods, Bob was able to get a full view of the watchful detectives, all of whom were seated on the grass in front of the hut, gazing at it so intently that there was no question that any suspicion had been aroused in their minds.

      Before they had left the hut Bob had placed the glycerine near the window, so that it could be reached from the outside, and, after it was learned that the enemy were still in blissful ignorance, but little time was lost in getting ready to return to Mr. Hoxie's well.

      Perhaps the boys were no more careless in carrying the glycerine this second time than they were the first, but they certainly walked faster, and when they arrived at their destination, they had been away such a short time that Ralph could hardly believe they had been to the hut in the woods and back.

      Everything was now in readiness for the important work, and the question that troubled the young moonlighters was whether the worthy Mr. Newcombe and his assistants would remain looking at the empty hut until the charge was exploded.

      CHAPTER VI

      TORPEDOING AN OIL-WELL

      It is safe to say that Ralph, who was interested in the shooting of the well only as a spectator, was the most nervous one of all that party who were about to show Mr. Hoxie whether he had "struck oil" or not.

      Bob set about the work with the air of one perfectly familiar with what he was doing, and the others aided him whenever it was possible, George alone remaining inactive, since he considered himself entitled to a seat with the spectator.

      The well had, of course, been bored down as far as the bed-rock, leaving an opening from eight to ten inches in diameter and quite twelve hundred feet deep, which was nearly filled with the water that had flowed in and the oil that had been poured in to give some slight resistance at the top of the cartridge.

      Over this, grim and weird-looking in the moonlight, rose the framework of the derrick, formed of heavy timbers, and apparently solid enough to resist any pressure that might be brought to bear upon it. Near by were scattered pieces of machinery, tools and such debris as would naturally accumulate around a place of the kind.

      A large reel, wound with heavy cord, capable of sustaining a hundred pounds' weight, and with a shallow hook, which would easily become detached when the pressure was removed, was fastened at one of the uprights of the derrick, while directly over the well was a block for the cord to pass through. This was to be used to lower the cartridges into the well.

      After this portion of the work had been completed – and all three of the moonlighters moved as rapidly as possible, lest Mr. Newcombe should put in an appearance – the task of filling the shells was begun. The tops of the long tin tubes were removed, and into these rather frail shells the glycerine was poured, Bob handling it as if it was no more dangerous than the petroleum they hoped to find.

      As fast as each tube or cartridge was filled it was lowered into the well by the stout wire bail that was fastened to the top, and just under the cover was the hammer which would explode the percussion cap when
