The Boy Hunters: Adventures in Search of a White Buffalo

According to Wikipedia: "Thomas Mayne Reid (April 4, 1818 – October 22, 1883), was an Irish-American novelist. "Captain" Reid wrote many adventure novels akin to those written by Frederick Marryat and Robert Louis Stevenson. He was a great admirer of Lord Byron. These novels contain action that takes place primarily in untamed settings: the American West, Mexico, South Africa, the Himalayas, and Jamaica."
