In Book I Thomas addresses Froude's claims in the early portions of The English in the West Indies. Froude's tendency to state incorrect assumptions as fact is roundly assaulted. Thomas criticizes Froude for making sweeping generalizations about the condition of blacks on multiple islands without ever talking or interacting with the people he was writing about. Thomas points out that Froude comments extensively on the lifestyles of the natives of Grenada when his only experience among the natives was peering into their houses as he rode past in a carriage. Thomas attacks many other different factual inaccuracies in Froude's work.
