'How do I know? Well, if you want to impugn my knowledge of mineralogy, I wish you would do so straight out. I either know my business or I do not. If you think I do not, then leave this matter entirely alone. I tell you that what I say about this mineral is true. What I say about its scarcity is true. There are no other mines with mineral so pure as this.'

'I am perfectly satisfied when you say that, but you must remember those who are going to put their money in this company will not be satisfied. They must have the facts and figures down before them, and they are not going to take either your word or mine as to the value of the mineral. Your proposal about seeing the different manufactories is good. I would act upon it at once, if I were you. We must have the opinions of practical men set forth clearly before we can make a move in the matter. Now, how much of this mineral have you got?'

'Only the few lumps I took with me in my portmanteau. The barrel full of it which we got at Burntpine has not arrived yet. I suppose it came by slow steamer and is probably on the ocean still.'

'Very good. Take what specimens you have, go to the North, and see those manufacturers. Get, in some way or another, whether from the principals or from the subordinates, the price they pay for it, and the cost of removing the adulteration from the stuff they employ now; because that is really the material we come into competition with. It is not with their first raw material, but with their material as cleared from the deleterious foreign substances, that we have to deal. Find out exactly what it costs to do this purifying, and then, when you get your facts and figures, I will arrange them for you in the best order. Meanwhile, as you suggest, I will learn what manufactories there are in the States. Nothing can be done except that until you come back, and, if I were you, I should leave at once.'

'I am quite ready. I don't want to lose any further time.'

So John Kenyon departed, and was soon on his way to the North, with a list of china manufactories in his note-book.

That afternoon Wentworth got the letters off by the American mail, and he felt that they were doing business as rapidly as could be expected. Next morning there was a letter for John Kenyon addressed to the care of Wentworth, and by a later mail there came a letter to Wentworth himself from John, who had reached his first district and had had an interview already with the manager of the works. He found the mineral was all he had expected, and they would be glad to take a certain quantity each year at a specified rate. This letter Wentworth filed away with a smile of satisfaction, and then he began again to wonder why Adam Brand, representing such a well-known manufactory, should have written a deliberate falsehood. Before he had time to fathom this mystery, the office-boy announced that a gentleman wished to see him, and handed Wentworth a card which bore the name of William Longworth. Wentworth arched his eyebrows as he looked at it.

'Ask the gentleman to step in, please,' he said; and the gentleman stepped in.

'How are you, Mr. Wentworth? I suppose you remember me, although I did not see much of you on board the steamer.'

'I remember you perfectly,' replied Wentworth. 'Won't you sit down?'
