"I'll take my leave now, sir," he said, "and must thank you for so kindly listening to my proposals. Hals, I thank you for the hospitality of your house. We meet again soon I hope."

He took up his hat and almost in spite of himself he acknowledged Diogenes' parting bow with one equally courteous. Patron and employé stood henceforth on equal terms.

"An you desire to see me again to-day, sir," he said before finally taking his leave, "I shall be in the tapperij of the 'Lame Cow' between the hours of four and five and entirely at your service."

After that he walked out of the room escorted by Frans Hals, and Diogenes who had remained alone in the big, bare studio, stood in front of Jongejuffrouw Beresteyn's portrait and had another long look at it.

A whimsical smile sat round his lips even as they apostrophized the image that looked so gravely on him out of the canvas.

"You poor, young, delicate creature!" he murmured, "what of your imperious little ways now? your offers of condescension, your gracious wiping of your dainty shoes on the commoner herd of humanity? Your own brother has thrown you at the mercy of a rogue, eh? A rogue whose valour must needs be rewarded by money and patronage!... Will you recognise him to-night I wonder, as the rogue he really is? the rogue paid to do work that is too dirty for exalted gentlemen's hands to touch? How you will loathe him after to-night!"

He drew in his breath with a quaint little sigh that had a thought of sadness in it, and turned away from the picture just as Frans Hals re-entered the room.

"When this picture is finished," he said at once to his friend, "your name, my dear Hals, will ring throughout Europe."

"'Tis your picture I want to finish," said the other reproachfully, "I have such a fine chance of selling it the day after to-morrow."

"Why the day after to-morrow?"
