Jacksonville and its adjacent towns number a population of over twelve thousand inhabitants, the whole area being three miles long and about two wide. The different names given to this small space of country looks larger on the map than in reality. These corporations are distinguished from each other by the names of Jacksonville, East Jacksonville, Brooklyn, La Villa, Riverside, Springfield, Hansom Town, etc.--each town containing, from fifty to fifteen hundred houses. The inhabitants say they were laid out into lots and named, with the expectation of a large increase of persons; consequently there are desirable building-spots in these surveyed sites for growing cities, for sale at all times upon moderate terms. Jacksonville makes a display of architectural skill, in which are seen the improvements of the nineteenth century. Yards and lawns are laid out fronting many of the residences, where the beauties of landscape gardening may be found blending in harmony with the artistically-arranged walks and pleasure promenades. The sidewalks are made of plank and brick, shaded and overhung with live-oaks, forming archways of inviting appearance, from which swings pendant moss, presenting a perennial, picturesque scene of nature's grandeur. There are over twenty church-edifices in and around the city, where both white and colored people come to worship in crowds. We are happy to state these statistics find the inhabitants in a much better spiritual condition than has been represented. However, we have no partiality for many of the doctrines preached by itinerant reformers who come here. We prefer our old orthodox faith, which made us contented while we lived, and carried us to heaven when we died. But these new isms, such as Spiritualism, Liberalism, Free-loveism, and every other species of modernized infidelity that is now gaining ground and receiving accessions from our Sunny South, are designed only to delude and drown the souls of their followers in eternal misery. The Churches here are representatives of various creeds and beliefs--Methodist, Presbyterian, Protestant Episcopalian, and Roman Catholic. The Sabbath dawns in Florida with its recreations and steam-boat excursions, well patronized by Northern visitors, as very few appear to bring their religion when they come South.
