“Did you ever see skies painted without blue, Master amateur?”

“I am not an amateur. I merely tell you, in passing—I make the casual remark—that that there is too much blue; but do as you like. Put more blue, if you don’t think you have troweled on enough already.”

“But I tell you, that I want to represent a clear, blue sky at sunrise.”

“And I tell you that no man in his senses would make a sky at sunrise blue.”

“By St. Gudula, this is too much!” exclaimed the painter, coming down from his ladder, at no pains this time to conceal his anger; “I should like to see how you would paint skies without blue.”

“I don’t pretend to much skill in sky-painting; but, if I were to make a trial, I wouldn’t put in too much blue.”

“And what would it look like if you didn’t?”

“Like nature, I hope, and not like yours, which might be taken for a bed of gentianella, or a sample of English cloth, or any thing you please—except a sky; I beg to assure you, for the tenth time, there is too much blue!”

“I tell you what, old gentleman,” cried the insulted artist, crossing his maul-stick over his shoulder, and looking very fierce, “I dare say you are a very worthy fellow when you are at home; but you should not be let out—alone.”

“Why not?”
