'Very well, then; I think I will just run over and see him.' 'Very good, sir; anything more, sir?' 'Nothing more, Close, thank you.' When the valuable Close had departed as softly and apologetically as he had entered, Wentworth picked up one of the specimens of spar which Kenyon had taken from the mine, and put it into his pocket. In two minutes more he was in a cab, dashing through the crowded streets towards Melville's office. By the side of the door of the china company's warehouse, inside the hall, were two parallel rows of names--one under the general heading of 'Out,' the other under the heading of 'In.' It appeared that Mr. Smith was out and Mr. Jones was in, but, what was more to the purpose, the name of Richard Melville happened to be in the column of those who were inside. After a few moments' delay, Wentworth was ushered into the office of this gentleman. 'Mr. Melville,' he said, 'I have been recommended to come to you for information regarding the china trade. The information I want, you will, perhaps, not be able to give me, but I believe you can tell me to whom I should apply for it.' Saying this, he took out of his pocket the specimen of mineral which he had brought with him. 'What I want to know is, how much of this material you use each year in the manufacture of china; what price you pay for it; and I should like to get at an estimate, if possible, of the quantity used in England every year.' Melville picked up the specimen and turned it round and round, looking at it attentively. 'Well,' he said at last, 'I could tell you anything you wished about the wholesale china trade, but about the manufacture of it I am not so well informed. Where did you get this?' 'That,' said Wentworth, 'is from a mine in which I am interested.' 'Ah, where is the mine situated, may I ask?' 'It is in America,' said Wentworth vaguely. 'I see. Have you considered the question of carriage in proposing to put it on the English market? That, as you know, is an important question. The cost of taking a heavy article a long distance is a great factor in the question of its commercial value.' 'I recognise that,' said Wentworth; 'and it is to enable me to form some estimate of the value of this material that I ask for particulars of its price here.' 'I understand, but I am not able to answer your questions. If you have time to wait and see Mr. Brand, our manager of the works, who is also one of the owners, he could easily tell you everything about this mineral--whether used at all or not. He comes up to London once every fortnight, and to-day is his day. I am expecting him here at any time. You might wait, if you liked, and see him.' 'I do not think that will be necessary. I will write, if you will allow me, just what I want to know, and in two or three minutes he could jot down the information I require. Then I will call again to-morrow, if you don't mind.'
