Baptisms used to be performed all along the rivers and may still be being done. Just wading into the water at the Louisville landing was a Perfect Act of Faith, for the mud was well-laced with broken bottles, old wire, packinghouse offal and all the other detritus of a big city. The church people would sing and shout responses to the preacher and the curious public would stand by and watch. These events were not publicised. It is a lucky thing the photographer came along to discover this one.
