"You had better write a note to him to-night, to give him quietly in the morning, as you may not have an opportunity for a long talk with him so early, and tell him what I have told you. Then he can probably make arrangements with Jack by writing, so that he will not need to go to the cabin again at present; or, if necessary, I can go for him." "But what will they do about their intended examination of the mines? They will surely be watched then." "All they can do is to make their plans as quietly and secretly as possible, and then go prepared for the worst, but I think I can help them there; I have a scheme of my own, something that occurred to me while listening to their conversation, which I will tell you later." The note was written, and it was nearly daylight, when the two at last retired, to rest possibly, but not to sleep. CHAPTER XXXIV. For the next ensuing days there were no more visits to the cabin. According to Lyle's suggestion, a few notes were quietly exchanged between Houston and Jack; thus their plans were maturing, while there was nothing which outsiders could detect. Meanwhile, Haight had bestowed considerable attention upon Miss Araminta Bixby, to the unspeakable delight of that individual, and had so ingratiated himself into her favor that she only too gladly consented to play the part of spy on the movements of Houston and Van Dorn. The two Maverick boys had also agreed to report to him whatever they were able to learn concerning these two. Houston and Van Dorn, however, did not seem quite so intimate of late. They were apparently as good friends as ever, but were not so frequently seen together. Nearly every evening, Van Dorn started out for a stroll, sometimes with Lyle, sometimes alone, often sauntering in the direction of the cabin, but never seen to enter; while Houston, after spending an hour or two with Miss Gladden, would walk down to the mines, and entering the various tunnels, or descending the shafts of one mine and another, would watch the night shift at their work, or inspect the workings, occasionally taking measurements here and there. On one of these trips Jack accompanied him, and on their return, they completed the arrangements for the visit to the Lucky Chance mine, the following night. On the afternoon of the next day, Houston returned to the house a little earlier than usual, having finished his work for the day at the mines and mills, and as he with Miss Gladden and Lyle, sat in the little porch, they were joined a few moments later by Van Dorn. In low tones the plans for the evening were discussed. "Of course," said Houston, "we shall go prepared for trouble, but I do not anticipate that we shall meet with any. Even if we are watched, our course of procedure will differ so slightly from what we have followed for a week past, I think it will not excite suspicion." "They have watched me so many evenings to no purpose, they may be off guard to-night," said Van Dorn.
