"It's the doctor--my old friend the doctor," exclaimed Clara and her father at the same moment, and Herr Sesemann smiled to himself at the thought of what his friend's opinion must have been of this new way of satisfying his thirst for water. That evening when Herr Sesemann and Fraulein Rottenmeier were alone, settling the household affairs, he informed her that he intended to keep Heidi; he found the child in a perfectly right state of mind, and his daughter liked her as a companion. "I desire, therefore," he continued, laying stress upon his words, "that the child shall be in every way kindly treated, and that her peculiarities shall not be looked upon as crimes. If you find her too much for you alone, I can hold out a prospect of help, for I am shortly expecting my mother here on a long visit, and she, as you know, can get on with anybody, whatever they may be like." "O yes, I know," replied Fraulein Rottenmeier, but there was no tone of relief in her voice as she thought of the coming help. Herr Sesemann was only home for a short time; he left for Paris again before the fortnight was over, comforting Clara, who could not bear that he should go from her again so soon, with the prospect of her grandmother's arrival, which was to take place in a few days' time. Herr Sesemann had indeed only just gone when a letter came from Frau Sesemann, announcing her arrival on the following day, and stating the hour when she might be expected, in order that a carriage should be sent to meet her at the station. Clara was overjoyed, and talked so much about her grandmother that evening, that Heidi began also to call her "grandmamma," which brought down on her a look of displeasure from Fraulein Rottenmeier; this, however, had no particular effect on Heidi, for she was accustomed now to being continually in that lady's black books. But as she was going to her room that night, Fraulein Rottenmeier waylaid her, and drawing her into her own, gave her strict injunctions as to how she was to address Frau Sesemann when she arrived; on no account was she to call her "grandmamma," but always to say "madam" to her. "Do you understand?" said the lady, as she saw a perplexed expression on Heidi's face. The latter had not understood, but seeing the severe expression of the lady's face she did not ask for more explanation. CHAPTER X. ANOTHER GRANDMOTHER
