"I have four engagements here to meet, and two in New York, before I can engage to paint any more. I left three unpainted in Chicago, which I had half promised to do. ...I must positively be in Munich by the 1st of May as I have an appointment there with a gentleman who desires to purchase my next large historical picture. I am at present painting Mr. & Mrs. Talbot and shall visit Boston for a day or so and will have the pleasure of talking over the matter of your portrait with you."
