Barbara felt only too plainly that it was time to leave her post of observation; her feet would scarcely carry her and, besides, she was freezing.

She had entered the damp cave chamber in a thin summer gown, and it now seemed to be continually growing colder and colder.

Climbing down the high steps taxed her like a difficult, almost impossible task, and perhaps she might not have succeeded in accomplishing it unaided; but she had scarcely commenced the descent when she heard her name called, and soon after Sister Hyacinthe entered the frigidarium and, amid no lack of kindly reproaches, helped her to reach the open air.

When even in the warm sunshine the chill did not pass away, Barbara saw that the sister was right, yet she was far from feeling repentant.

During the night a violent attack of fever seized her, and her inflamed throat was extremely painful.

When Dr. Mathys came to her bedside he already knew from the nun the cause of this unfortunate relapse, and he understood only too well what had induced Barbara to commit the grave imprudence.  Reproof and warnings were useless here; the only thing he could do was to act, and renew the conflict with the scarcely subdued illness.  Thanks to his indefatigable zeal, to the girl’s strong constitution, and to the watchful care of the nurse, he won the victory a second time.  Yet he could not rejoice in a complete triumph, for the severe inflammation of the bronchial tubes had caused a hoarseness which would yield to none of his remedies.  It might last a long time, and the thought that the purity of his patient’s voice was perhaps forever destroyed occasioned sincere regret.

True, he opposed the girl when she expressed this fear; but as July drew to its close, and her voice still remained husky, he scarcely hoped to be able to restore the old melody.  In other respects he might consider Barbara cured, and intrust her entire convalescence to her own patience and caution.

Perhaps the ardent desire to regain the divine gift of song would protect her from perilous ventures like this last one, and even more certainly the hope which she had confided to the nun and then to him also.  The physician noticed, with warm sympathy, how deeply this mysterious expectation had influenced her excitable nature, ever torn by varying emotions, and the excellent man was ready to aid her as a friend and intercessor.

Unfortunately, just at this time the pressure of business allowed the Emperor little leisure to listen to the voice of the heart.

The day before yesterday the Elector John Frederick of Saxony and the Landgrave Philip of Hesse had been banned, and with this the war began.
