The question is in the details

This is only a short answer space but I can make a general comment. Mattie mentally compares the rising sun to Blanchard's yellow balloon. Just as the balloon had symbolized a new era in the development of the city and nation, the rising sun marks the beginning of a new day, which will be met with newfound enthusiasm. Mattie has fully matured into a woman capable of operating her own business and managing her own household. She has an adopted child, cares for her frail mother, has forged solid friendships and business acquaintances, and has a serious suitor. For Mattie, the future is indeed beckoning.
