On this, the f first of January of the year 1851, the nineteenth century has reached its midway term, and many of us who shared its youth have already warnings which tell us that it has outworn us. We put our grizz­led heads together, we older ones, and we talk of the great days that we have known; but we find that when it is with our children that we talk it is a hard matter to make them understand. We and our fathers before us lived much the same life, but they with their railway trains and their steamboats belong to a different age. It is true that we can put history books into their han­ds, and they can read from them of our weary struggle of two and twenty years with that great and evil man.
