All the gentlemen in Frankfurt with tall black hats on their heads, and scorn and mockery in their faces rose up before his mind's eye, and he threw himself with energy on the Y, not letting it go till at last he knew it so thoroughly that he could see what it was like even when he shut his eyes. He arrived on the following day in a somewhat lofty frame of mind, for there was now only one letter to struggle over, and when Heidi began the lesson with reading aloud:-- Make haste with Z, if you're too slow Off to the Hottentots you'll go. Peter remarked scornfully, "I dare say, when no one knows even where such people live." "I assure you, Peter," replied Heidi, "grandfather knows all about them. Wait a second and I will run and ask him, for he is only over the way with the pastor." And she rose and ran to the door to put her words into action, but Peter cried out in a voice of agony,-- "Stop!" for he already saw himself being carried off by Alm-Uncle and the pastor and sent straight away to the Hottentots, since as yet he did not know his last letter. His cry of fear brought Heidi back. "What is the matter?" she asked in astonishment. "Nothing! come back! I am going to learn my letter," he said, stammering with fear.

So much the more eagerly did she pursue her teaching so that Peter might compensate for her absence by reading hymns to the old woman. One evening he walked in home after leaving Heidi, and as he entered he said, "I can do it now." "Do what, Peter?" asked his mother. "Read," he answered. "Do you really mean it? Did you hear that, Grandmother?" she called out. The grandmother had heard, and was already wondering how such a thing could have come to pass. "I must read one of the hymns now; Heidi told me to," he went on to inform them. His mother hastily brought the book, and the grandmother lay in joyful expectation, for it was so long since she had heard the good words. Peter sat down to the table and began to read. His mother sat beside him listening with surprise and exclaiming at the close of each verse, "Who would have thought it possible!" The grandmother did not speak though she followed the words he read with strained attention. It happened on the day following this that there was a reading lesson in Peter's class. When it came to his turn, the teacher said,--
