Acadia National Park attracts millions of people to Maine's Mount Desert Island in the summer. Most can't wait to perambulate around the famous summer colony of Bar Harbor, known for the grand seaside "cottages" built by the Rockefellers, Morgans and other wealthy Easterners. Tourists can also now see -- at the relocated and expanded Abbe Museum -- how Wabenaki tribes spent their summers on the island and intermingled with the so-called rusticators. It was an unusual, curious situation, to say the least, and Bunny McBride and Harald Prins have done illuminate in detail the two-cultures relationship in their new book, "Indians in Eden." It's a simply fascinating look at the everyday and difficult realities of life for the tribes amid such an elite class. The narrative is painstakingly researched -- a hallmark of McBride's and Prins' work. And there's a treasure-trove of photographs and illustrations that invite the reader to linger amid the details and try to imagine the good and bad of what it was like for the Indians during the late 19th century and early 20th century period. The book builds on the substantive contribution Prins and McBride have made to the tribes' understanding of themselves and to the rest of society's perspective on the Native American place in the state's history.
