But at any rate the pellucid ingenuousness of young person swho, (unless miserably infected by sectarian sentiments) have no predilections, should be attentively listened to, and delicately treated. A mind may be injured beyond remedy, which is roughly dealt with, or acrimoniously rebuked, in any instance of its not immediately falling in with a teacher's opinions.
