We must, first of all, guard against unclean language. There are some words which are merely filthy, without being immoral; both are bad, and the one leads to the other. Little boys often long to have other words to put into their language than they have learned at home, because they think the home language not strong enough or manly enough. In order to satisfy themselves that they are no longer children, they begin at school to copy the strong words of the boldest and most reckless of the boys they meet, and they quickly add to their vocabulary unclean and even immoral words, because such words seem to be the mark of manliness, and of personal independence of character. By the time that a boy begins to realize what such words really mean, he has already formed the habit of using unclean language, and a bad _habit_ is the hardest thing in the world to get rid of. Any one who thinks about the matter for a moment will admit that filthy language is not only not manly, but that it is degrading to the mind and character. One of the most manly characters of modern times was Coleridge Patteson, Bishop of Melanesia, who died in 1874, by the clubs of savage islanders, who, when he was dead, placed him in a boat with his hands crossed, and set him adrift upon the Pacific. We are told by an old schoolmate of his that once, when he was captain of the cricket eleven at Eton, some boys at the cricket dinner began to sing a coarse song. "Coley" Patteson had said that he would leave the room if such a song were sung, and as soon as they began it he quietly got up and went out. The result of his action was that the bad custom was stopped entirely. The old poet of Israel sang: "O Lord, keep the door of my lips." We all need to make that request. Another of the most manly men of modern times was General Grant, President of the United States. We are told of him that on one occasion, when a number of gentlemen were dining together, some one began to tell an indecent story. He commenced by saying: "I have a first-class story which I may tell, seeing that there are no ladies present." "No! but there are _gentlemen_ present," said General Grant, and the story was not told.
