There was a moment's pause now while the two men looked on one another eye to eye, appraising one another, each counting on his opponent's worth. Then Nicolaes suddenly turned back to Frans Hals.

"My good Hals," he said, "might I crave a favour from your friendship?"

"I am at your service, mynheer, now as always as you know," murmured the artist, who indeed was marvelling what favour so illustrious a gentleman could ask of a penniless painter of portraits.

"'Tis but a small matter to you," rejoined Nicolaes, "but it would be of great service to me. I desire to hold private conversation with this gentleman. Could I do so in your house without attracting anybody's attention?"

"Easily, sir. This room though none too comfortable is at your disposal. I have plenty of work to do in another part of my house. No one will come in here. You will be quite undisturbed."

"I am infinitely obliged to you. 'Tis but half-an-hour's privacy I desire ... providing this gentleman will grant me the interview."

"Like my friend Hals," rejoined Diogenes suavely, "I am, sir, at your service. The tides are rising around me, I feel them swelling even as I speak. I have an overwhelming desire to ride on the crest of the waves, rather than to duck under them against my will."

"I hope this intrusion will not retard your work too much, my good Hals," said Beresteyn with somewhat perfunctory solicitude when he saw that the artist finally put his brushes and palette on one side, and in an abstracted manner began to dust a couple of ricketty chairs and then place them close to the stove.

"Oh!" interposed Diogenes airily, "the joy of being of service to so bountiful a patron will more than compensate Frans Hals for this interruption to his work. Am I not right, old friend?" he added with just a soupçon of seriousness in the mocking tones of his voice.

Hals murmured a few words under his breath which certainly seemed to satisfy Beresteyn for the latter made no further attempt at apology, and only watched with obvious impatience the artist's slow progress out of the room.
