They were busy days which followed for Geoffrey Trethick, and his interviews with Mr Penwynn, in consequence of the latter’s desire to keep his name out of the project, were of an evening at An Morlock, where he more than once encountered Rhoda, who pleased him by the way in which she entered into the spirit of his plans.

The first time he met her was when, after a couple of visits to the mine where the Wheal Carnac machinery had been taken, and some long discussions with Pengelly, he had gone up to An Morlock to ask Mr Penwynn whether he would buy it back from the trustees of the bankrupt estate.

“But that will take quite a heavy sum, Trethick,” said Mr Penwynn. “What I want to do is to have the mine emptied and thoroughly tested without further expense.”

“Exactly so, sir,” replied Geoffrey; “but, working in your interests, I felt it my duty to lay this before you. Here, to pump out, a certain amount of money must be spent in fixing hired machinery. If the mine proves good all that money is wasted. On the other hand, if you are willing to buy back this original machinery, which is, I guarantee, to be had for a fourth of its value, it will do the work better, and you have it ready to carry on future proceedings, when a vast amount would be saved.”

“And suppose the venture—I mean the testing—proves a failure?”

“You have a valuable lot of modern machinery to sell, and cannot lose.”

Mr Penwynn sat thinking, and Rhoda raised her head from her work.

“Well, my dear,” said her father, smiling, “what should you do?”

“I think I should take Mr Trethick’s advice, papa,” she said quietly; and she had hardly spoken when the servant announced Mr Tregenna, who came in smiling, and shook hands warmly all round.

“I thought I’d just drop in for a chat,” he said, looking meaningly at Mr Penwynn. “Why, the place is ringing with the news that you are going in for mining.”
