The more she thought about the golden casket, the more curious she was to see what was in it; and every day she took it down from its shelf and felt of the lid, and tried to peer inside of it without opening it. She opened the lid a very little, just to peep inside. All at once there was a whirring, rustling sound, and before she could shut it down again, out flew ten thousand strange creatures with death-like faces and gaunt and dreadful forms, such as nobody in all the world had ever seen. They fluttered for a little while about the room, and then flew away to find dwelling-places wherever there were homes of men. They were diseases and cares; for up to that time mankind had not had any kind of sickness, nor felt any troubles of mind, nor worried about what the morrow might bring forth. These creatures flew into every house, and, without anyone seeing them, nestled down in the bosoms of men and women and children, and put an end to all their joy; and ever since that day they have been flitting Ind creeping, unseen and unheard, over all the land, bringing pain and sorrow and death into every household.
