At first she was only in fun, and enjoyed, as many of us do, making up stories about herself. Then gradually the idea of taking part in the big world beyond the gates became too precious to set aside, and at last it so possessed her, that she only waited for the chance of carrying it out. This happened when she was fifteen--a tall, strong, handsome girl full of energy and courage, and quick to decide whatever question came before her. * * * * * One day the nuns assembled as usual for vespers or evening prayers, and just as they were all going into chapel the Superior discovered that she had left her psalm-book upstairs, locked in her writing-table. Summoning Catalina, she handed her a key, and bade her unlock the drawer in which the book was kept, and bring it to her as fast as possible. The girl ran upstairs, but when she saw lying in the locked drawer, not only the book, but the key of the convent gate, it darted into her mind that now, if ever, was her opportunity to quit the convent. Yet even at that moment, she did not let her excitement get the better of her. She snatched up some loose money from the drawer and a small work-case that lay on a table and hid it in her dress, and without stopping a moment ran down to the great door of the convent, which she unlocked. She next rejoined her aunt who was waiting for her, and asked if she might go straight to bed, as she had a bad headache. In this manner she secured to herself a good start, as no one would think about her for hours to come. She passed through the door carefully, locking it after her, and crept cautiously along by the wall till she reached a chestnut wood on the outskirts of the town. Here she flung herself down on a heap of dry leaves and slept till sunrise. This, fortunately for her, was very early, as she had much to do before she continued her journey. Her dress would have told any passer-by that she was a nun, or at least that she had come from a convent, and that was the last thing they must ever guess! Slipping off therefore her white petticoat, Catalina began at once to turn it into trousers such as men then wore, and in three or four hours had finished a pair which, if not exactly fashionable, would pass unnoticed. She next managed to change her long robe into a cloak, and satisfied that she would do well enough, the girl started on a walk to a town not far off, where she had resolved to try and find shelter with an elderly cousin.
