“Dear Sir,—The bearer of this, Señor Manuel Lauré, comes to you with our earnest recommendation. He has certain peculiar projects that he will explain. To some people they would seem wild and visionary; but to you, with your appliances, they will doubtless appear in a very different light. He is a gentleman of good position here, and worthy of your respect. If you do not see fit to carry out his wishes, kindly place him in communication with some other firm, and do what you can to prevent his being imposed upon.—Faithfully yours,—

“Roberts and Moore.

“To Mr Parkley, Ramwich.”

“Glad to see you, sir,” said Mr Parkley, upon whom the letter wrought a complete change. “Good people, Roberts and Moore. Supplied them with a complete diving apparatus. So you’ve come over on purpose to offer me a fortune?”

“Yes,” said the visitor, “a great fortune. You smile, but listen. Do I think you a child, sir? Oh, no. I do not tell you I want to make a great fortune for you only, but for myself as well.”

“Of course,” said Mr Parkley, smiling, and showing in his manner how thoroughly business-like he was. “I thought that had to come.”

“See here, sir—This Mr Pugh is in your confidence?”

“Quite. Go on.”

“See, then: I have travelled much, boating—yachting you would call it in England—all around the shores of the Great Gulf of Mexico. I know every island and piece of coast in the Carib Sea.”

“Yes,” said Mr Parkley, drumming on the desk.

“I have made discoveries there.”

“Mines?” said Mr Parkley. “Not in my way.”
