Just then a thought occurred to Jack, and he took the Doctor aside for consultation.

"Doctor," he said, "It occurs to me that this coal mine, if it is a coal mine, is on my mother's land and that therefore it is worth my while and Harry's and Tom's to stay here and work up the possibilities of the case. It is also worth your while, because you are in fact the discoverer of it and my mother will naturally recognize your interest in it, especially as we shall look to you to find capitalists to work the thing."

"Oh, I'll do that, of course. If I'm right about the mine, I'll have no difficulty in finding plenty of capital. The mine is at exactly the right place, and as to my interest, I'll take care of that when I come to negotiate with the capitalists. I'll see to it that they allow me a proper commission for 'bringing the property to their attention,' as they phrase it. So don't bother about me."

"No, but I'm bothering about Ed and Jim. If they are to stay here and help us for a month or so, they must be paid in some way."

"Of course," answered the Doctor. "I've been so long thinking of our party as a unit, whose constituent members 'shared and shared alike,' that I had not thought of them as persons not interested in this new Camp Venture. Let me think a little!"

He bowed his head upon his hands for a time in meditation. Then he said:

"Of course your mother cannot work this mine herself. It will need at least a hundred thousand dollars of capital to make it productive—perhaps twice that sum. I know enough of the situation to know that I can arrange that without going out of my own family. My father and my brothers will put in the entire sum necessary—for I tell you there is a vastly valuable property here,—and will allow your mother her proper share of the stock for the mine itself. I'll arrange all that to her perfect satisfaction before anything is concluded. Indeed, I must do that. Otherwise she would naturally make somebody else her agent."

"Oh, she'll trust you, Doctor," interrupted Jack.

"It isn't a matter of trust, it's business," answered the Doctor. "But on purely business principles we shall be able to arrange for your mother to put in the property and my friends to put in the money capital. I shall not ask your mother for a cent, for she has been like a mother to me ever since I came down here for my health and began boarding with her. My own people will allow me out of their share, a sufficient interest to compensate me. Now, I undertake also that they or I shall allow to Ed and Jim, half a share each in the mine, supposing it to be capitalized at a hundred thousand dollars, in return for their services while we have to stay here."

"No, Doctor," said Jack, "I will not hear of that. If you'll furnish one-half share, I engage that my mother shall furnish the other. That will divide the thing equally."
