US History Classwork: Textbook Research

In this classwork I were researching the word savage and savagery.  Mariam-Webster  defines savage as "not domesticated or under human control" and "lacking the restraints normal to civilized human beings."  I then searched up the word "savages" in the textbook archive and found some interesting descriptions of Indians.  They were always referred to as savages and nothing else.  The textbook made it sound like Indians were easily provoked to violence and were a disease to western expansion.  The best example I found was when the textbook said that the wilderness was "infested by savages"

If I read this in school in the late 1800s I would think that Indians were always up to no good and were very violent.  But if I read this today I would think otherwise.
