“With agitated stealth, I glanced out into the empty hallway, locked the door of the studio, drew four shades over windows through which I might be seen, and crept to the rabbit cage.

“Opening it, I seized by the long ears the white-furred animal which had stared at me. The warm softness of its palpitating body raised my artistic desire to a frenzy. I pulled a table from the wall, and holding down the animal upon it I drew my knife. Overcoming the mad, futile struggles of the rabbit, I slit long incisions in the white back and belly. The blood welled out....

“Perfect fury of delight sent me to my canvas. My fingers trembled as I mixed the colors, but there was no indecision now, and no hint of muddiness in the result. I painted....

“You perhaps have seen a reproduction of that picture? It was called “THE LUSTS OF THE MAGI,” and now hangs in one of the Paris galleries. Some day it will grace the Louvre. And all because our white rabbit had sacrificed its heart’s blood.

“At eleven next morning Guarneresi himself, coming to the studio, found me exhausted and asleep upon the floor. When he demanded explanations, I pointed in silence to the finished picture upon my easel.

“I thought the man would go frantic. He regarded it for an instant, with intolerance fading from his bearded face. Then his mouth gaped open, and a succession of low exclamations in his native tongue came forth. His raised hands opened and shut in the gesture I knew to mean unrestrained delight.

“Suddenly he dashed to the easel, and, before I could offer resistance, he snatched down my picture and ran with it out of the studio and down the stairs into the narrow street. I followed, but I was not swift enough. He had disappeared.

“In half an hour he returned with four brother artists who had studios nearby. The others were more than lavish in their praise, terming my picture the greatest masterpiece turned out in the Quarter for years. Guarneresi himself was less demonstrative now, but I detected tears in his eyes when he turned to me.

“‘The pupil has become the master,’ he said simply. ‘Go! I did not teach you this, and I cannot teach you more. Always I shall boast, however, that Signor Pemberton painted his first great picture in my studio.’
