Until he was about fifty years of age his health had been excellent. But the various and increasing cares of his official position finally had their effect. The sedentary work involved in writing a dissertation on the affairs of his community, which prevented for a time his usual out-of-door exercise, was the immediate cause of a severe cough and other alarming symptoms of decline. His spirits, which had been uniformly cheerful, became depressed. A journey to the West to establish a branch community of the United Brethren in Indiana was temporarily beneficial, but his system was undermined and the progress of disease could not be stayed.

A widow and four sons survived him. All the sons entered the Moravian ministry. The eldest, Emil Adolphus de Schweinitz, was born in Salem, N. C., in 1816.

During the latter years of the father's life he used de in place of von in his name, and the sons have always used the new form.

Von Schweinitz was of high stature, erect carriage, and robust habit. The portrait accompanying this sketch is a copy of a miniature painted some years before his death, and consequently represents him in the prime of life. He had an unusually amiable and attractive disposition, which made him a general favorite with high and low. His conversational powers were of a high order, and contributed much to an ease of intercourse which was an important factor of his usefulness. Humor, anecdote, and repartee were always at his command, while the varied and exciting scenes through which he had passed and the prominent per-
