What did a 19th century pastor want his motherless daughter to know as she set out in life?

William Buell Sprague, author and editor of wonderful biographies of American pastors (soon to be posted here!), also wrote beautiful and instructive letters to his daughter. Her mother (his wife) had passed away some time previously, and so he desired to set down in writing his hopes and dreams and directions for her as she prepared to go out from his household. These letters are not only of historical significance, but also are of great practical value even to us in the 21st century today. To be sure, times have changed - but with chapters such as "Early Friendships," "Marriage," "Improvement of Time," "Practical Religion," and "Humility," surely our Christian daughters could benefit from Sprague's book.
