"Fifty thousand flying devils!" roared Valdez pounding the table with his fist. "Dost thou think the Spanish treasury is a mine of diamonds? Away with thee, thou scurvy rascal! Come, Borgia! 'tis useless parleying with a madman!"

"Gentlemen," remarked Dirk, quite unmoved by this outburst on the part of the Spanish general, "you do me wrong. Did you but know my plan, you would say it was easily worth full twice the amount I have named. However, I have other ways of disposing profitably of my secret, should my terms not appeal to you!" In the silence that ensued, the two listeners could imagine the Spaniards consulting each other with uncertain glances. At last the voice of Valdez spoke again, this time in a more conciliatory tone:

"Willumhoog, I am not authorized to offer any such amount as thou dost name. But I swear to thee that I will consult with one ever gracious and merciful King Philip II, at the earliest opportunity, to obtain this amount for thee, using every influence in my power."

"Will your worship put that down in writing?" inquired Dirk eagerly.

"Certainly, certainly!" replied the general, glad to have made an impression so easily. Dirk hastened out, evidently to obtain pen and paper, and was back again in a jiffy. "I have one more request to make," he remarked in honeyed tones. "As thou wilt!" said Valdez.

"It is that your worship will write at my dictation."

There was another uneasy pause, and then the general acquiesced, muttering that he did not have to write anything that he did not wish!

"I, General Valdez," dictated Dirk, "Commander of the Spanish army before Leyden, do hereby give my promise that I will intercede with His Majesty, Philip II, to pay over to Dirk Willumhoog, for the valuable secret he shall impart concerning an unknown entrance into the city, the sum of fifty thousand florins." Scratch, scratch went the pen, and coming to this point, Valdez exclaimed: "There now I will sign my name!"

"Not quite yet!" said Dirk quietly. "There is something else!"—"And if I do not succeed in so persuading His Majesty, I stand ready to reimburse said Dirk Willumhoog for the amount remaining above what he shall have already received, out of my own private funds and estates."

"Never!" shouted Valdez, springing to his feet and clanking around the room. "Dost thou take me for a natural-born fool, thou sneaking rascal!"
