Then she glanced at her father, her eyes big and somewhat startled in expression. The Professor was deeply engrossed in a letter from Benjamin Lowenstein which declared that a certain note must be paid at maturity.

He wore a dressing-gown of soiled quilted silk and linen not too immaculate; but his little sandy moustache and the goatee that decorated his receding chin were both carefully waxed into sharp points--an indication that he possessed at least one vanity. Three days in the week he taught vocal and instrumental music to the ambitious young ladies of Cloverton. The other three days he rode to Pelham's Grove, ten miles away, and taught music to all who wished to acquire that desirable accomplishment. But the towns were small and the fees not large, so that Professor De Graf had much difficulty in securing an income sufficient for the needs of his family.
