RELIGIOUS SECTS.--There are episcopalians, presbyterians, methodists, catholics, baptists, and perhaps some other denominations of christians. They appear to live together in unity, and agree to disagree in opinion about their several forms of worship. To the community at large it matters little what may be their several forms, so as they have the same great fundamental principles of charity and benevolence towards each other and towards God and man. There are too, some quakers, as I perceive by their dress and conversation.--They are the same industrious, neat, quiet, friendly people every where. On Sunday April 14th I attended church in the morning at the first presbyterian church, and in the afternoon at Christ church, the oldest episcopalian church. In the forenoon I heard the Rev. Mr. Harrison. Calling at Mr. Cazenove’s to accompany him, he being absent, I went to the dwelling of his son-in-law, expecting to find him there, but, learning the object of my calling, a daughter of my deceased friend, the late Colonel FOWLE, came forward, and accompanied me to the church; she was a child nine or ten years old. She behaved perfectly lady-like, and conducted me to her mother’s pew, where her parent was already seated. The congregation was not a large one, though a very serious and devout one, to whom the preacher addressed a very good discourse. Colonel FOWLE was lost in the MOSELLE, when that vessel was blown up at Cincinnati, a few years since. I shook hands with him, and bid him farewell, only fifteen minutes before his death. I had been personally well acquainted with the Colonel for many years, and had spent many happy hours at different places in the West with him, on many a day, and I always had a high regard for him. His little daughter resembles him very much in her looks and manners. I could not refrain from thinking how happy he would have been, had he seen her, and noticed how lady-like his daughter was, in her behaviour, while conducting his old friend to church, in this city. If spirits hover around those friends whom they have left behind them in this world, and take a peculiar pleasure in any thing that relates to them in this life, the spirit of my departed friend, Col. Fowle, must have been pleased to see me seated in his pew, yesterday, at church, with his widow, her father and his daughter.
