“Oh!” said Helen. “A real mine?”

“That is what is puzzling Uncle Jabez, as I understand it,” said Ruth soberly. “He isn’t sure whether it is a real mine, or not. You see, he is very close mouthed, as well as close in money matters. He never said much to me about it. But old Aunt Alvirah told me all she knew.

“You see, that young man came to the mill as an agent for a vacuum cleaner, and he talked Uncle Jabez into buying one for Aunt Alvirah. Now, you must know he was pretty smart to talk money right out of Uncle’s pocket for any such thing as that,” and Ruth laughed; but she became grave in a moment, and continued:

“Not that he isn’t as kind as he knows how to be to Aunt Alvirah; but the fact that the young man made his sale so quickly gave Uncle Jabez a very good opinion of his ability. So they got to talking, and the young man told uncle about the Tintacker Mine.”

“Gold or silver?” asked Helen.

“Silver. The young fellow was very enthusiastic. He knew something about mines, and he had been out here to see this one. It had been the only legacy, so he said, that his father had left his family. He was the oldest, and the only boy, and his mother and the girls depended upon him. Their circumstances were cramped, and if he could not work this Tintacker Mine he did not know how he should support the family. There was money needed to develop the mine and—I am not sure—but I believe there was some other man had a share in it and must be bought out. At least, uncle furnished a large sum of money.”

“And then?” demanded Helen Cameron.

“Why, then the young man came out this way. Aunt Alvirah said that Uncle Jabez got one letter from Denver and another from a place called Butte, Montana. Then nothing more came. Uncle’s letters have been unanswered. That’s ever since some time last winter. You see, uncle hates to spend more money, I suppose. He maybe doesn’t know how to have the mine searched for. But he told me that the young man said something about going to Bullhide, and I am going to try to find out if anybody knows anything about the Tintacker Mine the first time we drive over to town.”

All this time Mary Cox had been deeply interested in what Ruth said. It was not often that The Fox paid much attention to Ruth Fielding, for she held a grudge against the girl of the Red Mill, and had, on several occasions, been very mean to Ruth. On the other hand, Ruth had twice aided in saving The Fox from drowning, and had the latter not been a very mean-spirited girl she would have been grateful to Ruth.

About the time that Ruth had completed her story of the Tintacker Mine and the utter disappearance of the young man who had interested her Uncle Jabez in that mysterious silver horde, Jane Ann called them all to supper. A long, low-ceiled, cool apartment was the dining-room at Silver Ranch. Through a long gallery the Mexican woman shuffled in with the hot viands from the kitchen. Two little dark-skinned boys helped her; they were Maria’s children.
