hope I helped !
Answer:
It would be difficult and lonely.
Explanation:
Dearest Francis,
I hope that this letter finds you happy and good of health. Life here in the New World is not easy, but if the elements cooperate, the benefits can be good. Winters here are longer and more bitter than in France, but the spectacular landscapes to in many ways compensate for the frigid conditions. Cities here would not be cities back home, but any speck of civilization can bring joy to the heart after weeks of trapping in the wilderness.
Until our paths cross again,
Marcus
