'Carry On, Mr. Bowditch' was an informative and enlightening story about early navigation. The book follows the life of Nathaniel Bowditch, a man who revolutionized and improved navigation in the late 1700s and early 1800s. Having received very little education, Bowditch, after working all day at a ship chandlery, would study many subjects on his own during the night. Through this study and other helps he mastered three languages besides English, learned astronomy, improved his algebraic skills, and contributed a wealth of knowledge to navigation. He made many voyages to sea, wrote a navigation book, and received an honorary degree from Harvard. 'Carry On, Mr. Bowditch' is a very informative book on the life of this ingenious man.
