"At last we drew lots and Millet was elected to die. We collected the few things we had left and pawned them. So we got a little money for travel and for Millet to live on for a few days. The next morning Claude, Carl and I left the village. Each had some of Millet's small pictures and sketches with him. We took different roads. Carl went to Paris, where he would begin the work of building Millet's fame. Claude and I were going abroad.

"On the second day I began to sketch a villa near a big town because I saw the owner standing on the veranda. He came down to look on. I showed him my sketch and he liked it. Then I took out a picture by Millet and pointed to the name in the corner.

“Do you know the name?” I said proudly. “Well, he taught me!” I finished.

"The man looked confused.

“Don't you know the name of Francois Millet?” I asked him.

“Of course it is Millet. I recognise it now”, said the man, who had never heard of Millet before, but now pretended to know the name. Then he said that he wanted to buy the picture. At first I refused to sell it, but in the end I let him have it for eight hundred francs. I made a very nice picture of that man's house and wanted to offer it to him for ten francs, but remembered that I was the pupil of such a master, so I sold it to him for a hundred. I sent the eight hundred francs straight back to Millet from that town and was on the road again next day.

"Nom that I had some money in my pocket, I did not walk from place to place. I rode. I continued my journey and sold a picture a day. I always said to the man who bought it, “I'm a fool to sell a picture by Ftancois Millet. The man won't live three months. When he dies, his pictures will be sold at a very high price”.

"The plan of selling pictures was successful with all of us. I walked only two days. Claude walked two – both of us afraid to make Millet famous too near the village where he lived – but Carl walked only half a day and after that he travelled like a king. In every town that we visited, we met the editor of the newspaper and asked him to publish a few words about the master's health. We never called Millet a genius. The readers understood that everybody knew Millet. Sometimes the words were hopeful, sometimes tearful. We always marked these articles and sent the papers to all the people who had bought pictures of us.

"Carl was soon in Paris. He made friends with the journalists and Millet's condition was reported to England and all over the continent, and America, and everywhere.

"At the end of six weeks from the start, me three met in Paris and decided to stop asking for more pictures from Millet. We saw that is was time to strike. So we wrote Millet to go to bed and begin to prepare for his death. We wanted him to die in ten days, if he could get ready. Then we counted the money and found that we had sold eighty-five small pictures and sketches and had sixty-nine thousand francs. How happy we were!

"Claude and I packed up and went back to the village to look after Millet in his last days and keep people out of the house. We sent daily bulletins to Carl in Paris for the papers of several continents with the information for a waiting world. The sad end came at last, and Carl came to the village to help us. Large crowds of people from far and near attended the funeral. We four carried the coffin. There was only a wax figure in it. Millet was disguised as a relative and helped to carry his own coffin.

"After the funeral we continued selling Millet's pictures. We got so much money that we did not know what to do with it. There is a man in Paris today who has seventy Millet's pictures. He paid us two million francs for them."
