The old minister listened gravely, with an inward smile, and told his deacon that he would attend to his suggestion. After the deacon had gone, he tumbled over his manuscripts, until at length he came upon his first-rate old sermon on “Human Nature.” He had read a great deal of hard theology, and had at last reached that curious state which is so common in good ministers,--that, namely, in which they contrive to switch off their logical faculties on the narrow sidetrack of their technical dogmas, while the great freight-train of their substantial human qualities keeps in the main highway of common-sense, in which kindly souls are always found by all who approach them by their human side. The Doctor read his sermon with a pleasant, paternal interest: it was well argued from his premises. Here and there he dashed his pen through a harsh expression. Now and then he added an explanation or qualified abroad statement. But his mind was on the logical side-track, and he followed the chain of reasoning without fairly perceiving where it would lead him, if he carried it into real life. He was just touching up the final proposition, when his granddaughter, Letty, once before referred to, came into the room with her smiling face and lively movement. Miss Letty or Letitia Forrester was a city-bred girl of some fifteen or sixteen years old, who was passing the summer with her grandfather for the sake of country air and quiet. It was a sensible arrangement; for, having the promise of figuring as a belle by and by, and being a little given to dancing, and having a voice which drew a pretty dense circle around the piano when she sat down to play and sing, it was hard to keep her from being carried into society before her time, by the mere force of mutual attraction. Fortunately, she had some quiet as well as some social tastes, and was willing enough to pass two or three of the summer months in the country, where she was much better bestowed than she would have been at one of those watering-places where so many half-formed girls get prematurely hardened in the vice of self-consciousness.
