Mrs. Harriet Beecher Stowe is here to-day from her home in Mandarin, for the purpose of attending church. Dr. Stowe, her husband, accompanies her as he preaches. When they both entered the Southern Methodist church a slight rustle was heard in the congregation, and a few persons left the house. Mr. and Mrs. Uncle Tom were more than a Sabbath dose for some of the Jacksonville community. Harriet B. has no resemblance to a perpetrator of discord or scandal, or one who has swayed the divining-rod of Abolitionism with sufficient potency to immortalize herself for many coming generations, or probed the private life of a man who, during the period of his checkered existence, never carved out virtue for his shrine. The three snowy curls on each side of her face give her a matronly look, and her stout-built frame, well covered with flesh, a substantial appearance. The service was opened by a very long prayer from Dr. Stowe, after which he preached a purely orthodox sermon on the subject of godliness. Mrs. Harriet had confidence in the ability of her husband; she knew the discourse would be right without her vigilant eye, and she went to sleep. Like other sleepers, she nodded naturally; her digits were concealed beneath kid covers, and thrusting at no one. She looked the picture of content, and was no doubt dreaming of that far-off, beautiful country, where those who create dissensions and stir up strife can never enter. Places of worship have had an existence for both colors throughout the entire South since the country was settled, the negroes being naturally inclined to religion more than the whites. The African Church has always been a full-developed institution, attended with its peculiarities and noisy accompaniments, where the colored zealots could always give vent to their religious enthusiasm by howling their emotional feelings among others equally excited. The preacher usually leads the singing with his loud, soul-stirring strains, manifesting much fervor, sometimes improvising a strain or two with his own invention, if the rhyme and tune do not measure equal. The following is a correct copy of an original sermon delivered by a very black Baptist brother to a Jacksonville colored congregation a short time previous to the Freedmen's Bank explosion, which appears prophetic in regard to that swindling institution. The text was, "Lay up for yourselves treasure in heaven":
