Pick up that oyster shell. Do you see a little hole in the hard roof of the oyster's house? That explains why there is a shell but no oyster. A little creature called the whelk, living in a spiral shell, dropped one day on the roof of the oyster's house. "The little innocents," some one has called the whelk. "The little villains," an oyster would call them, for the whelk has an auger, and bores and bores and bores until he reaches the oyster itself, and the poor oyster finds he is going up through his own roof. He goes up, but he never comes down. A writer speaks of noticing on the shores of Brittany the holes in the oyster bored by its enemy, both burglar and murderer we should call him. "A little sin, a little sin!" cries a boy who may have been caught saying a profane word, or strolling with a bad associate, or reading a bad book, or sipping a glass of beer. "Don't make too much of it!" he says. Young friend, that is the whelk on the oyster's back. You have given the tempter a chance to use his auger, and he will bore and bore till he reaches the center of all moral worth in the soul, and draws your very life away.
