Marshall thanks Henry for his letter of Feb. 27 and is sorry he cannot revisit Detroit. He sets out for the east on Monday next, taking Wheeling and Buffalo on his way to New York. His engagements in New England will occupy him till about the 14th of April, after which he reserves ten days for work in Canada, amd that will finish his campaign. His only chance of being able to visit Detroit again would be by having an engagement there on the 16th or 17th of April, on his way to Toronto and Montreal, for his personal benefit. After lecturing for three months, he has found that he is making money for others rather than himself. He thanks Mrs. Brownson for her kind remembrance of him and requests the photograph to be sent to "60 Park Avenue, N.Y." where he shall spend Holy Week. He asks for Mrs. Van Dyke's promised photograph also. P.S. It would be best to address mail for Marshall to Sadlier Co., 31 Barclay Street, New York. :: III-3-a A.L.S. 3pp. 12mo.
