Final answer:
The policy for American Indians in the late 19th century was implemented through the establishment of American Indian boarding schools, forcing cultural assimilation by prohibiting use of their native language and customs.
Step-by-step explanation:
The means for implementing the policy against American Indians in the late 19th century, resulting from reports mentioned, was via the establishment of American Indian boarding schools. The program intended to assimilate American Indian children into the 'American' way of life, which was predominantly an effort to erode their native histories, customs, and languages. This fits into the concept of cultural genocide that took place during this period. For instance, students at these schools were not only taught English but were also prohibited from using their native language and were given English names. Lastly, these were compulsory, meaning American Indian children were often forcibly removed from their families to attend.
