Along a quiet, shady path, also leading to the church, a lady was slowly and thoughtfully walking, on whose countenance a slight shade of sadness, apparently, contended with happier thoughts. It was Mary Preston's last Sunday in her old home, previous to exchanging it for the new one to which she had been looking forward so long; and full as her heart was of thankfulness to God for the blessings He had bestowed, she could not take farewell of the Sunday school in which she had taught for several years, without some regret and many misgivings. Where, indeed, is the earnest teacher, however faithful, who can lay down the self-imposed task without some such feelings? Has the heart been in the work? Have thought and earnestness entered into the weekly instruction? Has a Christian example given force to the precepts inculcated? Above all, has there been earnest, persevering prayer to the Lord of the harvest, in dependence on whom alone the joyful reaping time can be expected? Such were some of the questions which had been passing through Miss Preston's mind; and the smile with which she greeted her class as she took her place was a little shadowed by her self-condemning reflections -- reflections which her fellow-teachers would have thought quite uncalled for in one who had been the most zealous and conscientious worker in that Sunday school. But Mary Preston little thought of comparing herself with others. She knew that to whom "much is given, of him shall be much required;" and judging herself by this standard, she felt how little she had rendered to the Lord for His benefits to her. As her wistful glance strayed during the opening hymn to the faces of her scholars, she could not help wondering what influence the remembrance of what she had tried to teach them would exert on their future lives. As her class had been much diminished by recent changes, and in view of her approaching departure the blanks had not been filled up, it consisted on this Sunday of only three girls, of ages varying from twelve to fourteen, but differing much in appearance, and still more widely in character and in the circumstances of their lives.
