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.
