I would encourage everyone unfamiliar with this delightful little book to take advantage of the online version. It gives a good many of Irving's letters home in full, and reproduces a sketch he made of the "Erebus" and "Terror" at their final port of call in Greenland. The final letter, enclosed with this sketch, concludes with this poignant reflection:
We are going to have a school for the men, and our Captain reads prayers in Sundays. We are exempt from many of the temptations of the world, and I hope we shall have grace to find that it has been good for us to have been separated from the world, and that God has been with us in all our wanderings. May we submit ourselves to His pleasure in all things.
