Only four days ago, right in the next farm house to the one where I am spending the summer, a grandmother, old and gray and sweet, one of the loveliest spirits in the land, was sitting at her work, when her young grandson crept in and got down an old, battered, rusty gun which had not been touched for many years and was supposed not to be loaded, and pointed it at her, laughing, and threatening to shoot. In her fright she ran screaming and pleading toward the door on the other side of the room; but as she passed him he placed the gun almost against her very breast and pulled the trigger! He had supposed it was not loaded. And he was right: it wasn’t. So there wasn’t any harm done.
