Wadsworth residence, a fine mansion set back from the roadway, with beautiful trees and shrubbery surrounding it. Down at the great gateway stood Professor Potts, now white-haired and somewhat bent, but with a kindly smile of welcome on his face. Dave waved his hat and the old gentleman bowed with old-fashioned courtesy. Then the touring-car swept up to the broad front piazza and Mrs. Wadsworth showed herself.

      "Home again, are you, Dave," she said, pleasantly. "I am glad to see you." And then she allowed him to kiss her. There had been a time when Dave had been somewhat afraid of this stately lady of society, but that time was past now, and Mrs. Wadsworth looked on Dave almost as a son,--indeed, it had been this affection for the youth which had caused the two families to live under the same roof.

      Dave was soon up in his room, putting away his things and getting ready for dinner, which would be served in half an hour. He was almost ready to go below when he saw Caspar Potts pass through the hallway.

      "Well, Professor, how have you been?" he asked, pleasantly.

      "Very well, David, very well," was the somewhat slow reply. "It is a very pleasant life here, very pleasant!" And the eyes of the old college professor glistened.

      "Got the library in shape now, I suppose?" went on Dave, for he knew that was the old gentleman's hobby.

      "Yes, David, we have every book and pamphlet catalogued. And I am adding something new," continued the professor. "I am getting the autographs of many of the writers and pasting them on the fly-leaves. And where a writer dies and I get a printed obituary notice I paste that in the back of the book. I think it adds something to a volume to know about the writer and to have his or her autograph."

      "Fine, Professor!" cried Dave, and tapped him on the shoulder. "My, but it is nice here! Much better than the old farm, eh, and the poor-house that I came from!"

      The old gentleman nodded several times, and the tears stood in his eyes.

      "Yes! yes! It is very, very nice. I have found real friends, and I am thankful, very thankful!" And he continued on his way down the hall, wiping his eyes with his handkerchief.

      On the stairs Dave met Jessie. She was in a fresh dress of white, and had a rose in her hair.

      "How pretty you look!" he whispered, as he took her arm. "Just like a--a picture!" And then Jessie blushed and that made her look prettier than ever, if such a thing were possible.

      Dave's father and Mr. Wadsworth had come in, and both were glad to see the boy back. Soon dinner was announced, and all sat down to the long table, Dave between his sister and Jessie. It was old Professor Potts who asked grace; and then some rapid-fire conversation followed, the girls and the others demanding to know all about what had happened at Senator Morr's home, and about the lost mine.

      "It certainly sounds like a romance!" declared Dave's father, referring to the lost mine.

      "But I have heard of such things before," answered his brother. "I know of several valuable mines in South America that were lost through earthquakes. Landslides have not only buried mines, they have buried cities as well."

      "Oh, Dave, supposing you went to look for that mine and there was another landslide!" gasped Jessie, and turned pale.

      "That's a risk we'd have to run," was his answer. "But I'd be very careful as to where I went, Jessie."

      "I don't know about this," put in Mr. David Porter, with a grave shake of his head. "Better take the trip through Yellowstone Park, Dave, and let the Landslide Mine slide," and he smiled, faintly.

      "Oh, I promised Roger that I'd go with him,--and Phil is going, too!" pleaded Dave. "We'll be very careful."

      "I might go with you myself, only I think I ought to stay with the party to go through the Park," said Dunston Porter.

      "Yes, we want you with us!" cried Laura.

      "I don't like this at all!" pouted Jessie, and looked somewhat reproachfully at Dave.

      "Oh, you mustn't take it that way!" cried the youth. "Why, we'll be with you on the trip to the Park, and then we'll join you on the tour a little later. You are to stay at least four weeks, remember. Well, if we spent two or even three weeks looking for that mine we'd still have a week in the Park--and one can go through in six days, so the circular says."

      After that the talk became general, Dave learning more concerning the tour and who from Crumville and vicinity had signed to go, and the others asking for the details concerning the mine, and about the doings of Job Haskers and Link Merwell.

      "You steer clear of that rascally teacher and young Merwell," advised Dave's father. "They are a bad lot."

      "I'll steer clear if I can," answered Dave. "But if I catch them in any wrongdoing and I can manage it, I am going to have both of them arrested."

      "I'd not blame you for that."

      After the meal Dave spent a pleasant evening with Laura and Jessie. The three young folks went out on the porch and there, a little later, Ben Basswood joined them. All talked about the trip to Yellowstone Park, and about the Landslide Mine.

      "I'd like to go after that mine myself," said Ben. "But I know I can't do it, for I promised mother and my Aunt Kate that I'd stay with them all through the trip."

      "Then you'll have to stay with Laura and Jessie, too," returned Dave. "I'll leave them in your care while I am away."

      "Oh, Dave, as if Uncle Dunston wasn't going along!" cried his sister.

      "Well, you can't have too many protectors, in such a wild portion of our country," and Dave laughed, for he knew as well as did all of them that the trip through Yellowstone Park is a perfectly safe one.

      By and by Ben walked around the garden with Laura, while Dave took Jessie. It was moonlight and perhaps some sentimental things were said. Anyway, when Dave and Jessie came back he held her arm and both looked very contented. Then Ben had to go, and Dave walked down to the gateway with him and spoke about Nat Poole.

      "Well, if he reforms he's a good one," was all Ben said. He and Nat had been on the outs for a long while.

      "He'll do it," answered Dave. "At least, I hope so."

      CHAPTER XI

      OVERHEARD IN THE SUMMER-HOUSE

      "Dave, what do you think! I saw Link Merwell this morning!"

      It was Laura who spoke, as she burst into her brother's room, where the youth was looking over the things he expected to take with him on his trip West.

      "You saw Link Merwell!" cried Dave, dropping some collars he held in his hand. "Where?"

      "Down on Main Street, near the post-office."

      "Did he speak to you?"

      "Oh, no, the minute he noticed that I saw him he hurried out of sight around the corner. I followed to the corner, but when I got there he had gone."

      "Was Job Haskers with him?"

      "I didn't see him."

      "Humph! This is interesting, to say the least," mused Dave. He thought of what Nat Poole had told him, and of what Merwell and Haskers had attempted at the Morr homestead. "I'll have to look into this," he added, aloud.

      "Oh, Dave, do you think he'll try to do something more round here--or at the jewelry works?"

      "I'll warn Mr. Wadsworth, Laura, and he can notify the police. But it's queer Merwell should show himself, knowing there is a warrant out for his arrest. Weren't you mistaken?"

      "I don't think so. Of course he had on a slouch hat, drawn down over his eyes, and an unusual suit of clothing, but I am pretty certain
