Again and again and again, my sister had traced upon the slate, a character that looked like a curious T, and then with the utmost eagerness had called our attention to it as something she particularly wanted. I had in vain tried everything producible that began with a T, from tar to toast and tub. At length it had come into my head that the sign looked like a hammer, and on my lustily calling that word in my sister's ear, she had begun to hammer on the table and had expressed a qualified assent. Thereupon, I had brought in all our hammers, one after another, but without avail. Then I bethought me of a crutch, the shape being much the same, and I borrowed one in the village, and displayed it to my sister with considerable confidence. But she shook her head to that extent when she was shown it, that we were terrified lest in her weak and shattered state she should dislocate her neck.

     When my sister found that Biddy was very quick to understand her, this mysterious sign reappeared on the slate. Biddy looked thoughtfully at it, heard my explanation, looked thoughtfully at my sister, looked thoughtfully at Joe (who was always represented on the slate by his initial letter), and ran into the forge, followed by Joe and me.

     "Why, of course!" cried Biddy, with an exultant face. "Don't you see? It's him!"
