These lofty thoughts were disturbed by the unexpected arrival in the library of mademoiselle de la Mole. He was so animated by his admiration for the great qualities of such invincibles as Danton, Mirabeau, and Carnot that, though he fixed his eyes on mademoiselle de la Mole, he neither gave her a thought nor bowed to her, and scarcely even saw her. When finally his big, open eyes realized her presence, their expression vanished. Mademoiselle de la Mole noticed it with bitterness. It was in vain that she asked him for Vély's History of France which was on the highest shelf, and thus necessitated Julien going to fetch the longer of the two ladders. Julien had brought the ladder and had fetched the volume and given it to her, but had not yet been able to give her a single thought. As he was taking the ladder back he hit in his hurry one of the glass panes in the library with his elbow; the noise of the glass falling on the floor finally brought him to himself. He hastened to apologise to mademoiselle de la Mole. He tried to be polite and was certainly nothing more. Mathilde saw clearly that she had disturbed him, and that he would have preferred to have gone on thinking about what he had been engrossed in before her arrival, to speaking to her. After looking at him for some time she went slowly away. Julien watched her walk. He enjoyed the contrast of her present dress with the elegant magnificence of the previous night.

"I must read over again all the letters I have written this morning. God knows how many missed out words and blunders I shall find. As he was forcing himself to concentrate his mind on the first of these letters he heard the rustle of a silk dress near him. He suddenly turned round, mademoiselle de la Mole was two yards from his table, she was smiling. This second interruption put Julien into a bad temper. Mathilde had just fully realized that she meant nothing to this young man. Her smile was intended to hide her embarrassment; she succeeded in doing so. "You are evidently thinking of something very interesting, Monsieur Sorel. Is it not some curious anecdote about that conspiracy which is responsible for comte Altamira being in Paris? Tell me what it is about, I am burning to know. I will be discreet, I swear it." She was astonished at hearing herself utter these words. What! was she asking a favour of an inferior! Her embarrassment increased, and she added with a little touch of flippancy,
