What on earth is the matter with Susan? Up to yesterday morning I have hardly had to find fault with her more than twice or thrice in four years. Yet, since last night, she has richly deserved a dozen sharp scoldings at the very least. After all, poor Grandmamma must have been right. "My pet," grannie used to say whenever I told her that Susan was a treasure of pure gold; "My pet, I have had thirty or forty treasures myself, and I give you my word that even the best of them are only plated. Off the worst ones the plating wears soon. Off the better ones it wears late. But wait long enough, and sooner or later you shall see the copper or the pewter."
