This book describes the adventures of four boys who join in a trip up the Great Lakes to Duluth, where they take a private car furnished by the father of one of them and visit Yellowstone Park.

Four boys are at camp on the Arkansas River, and are so fascinated by good comradeship and interesting sights and experiences that they prolong their travelling by a most enviable trip on the mighty Mississippi River.

An exploration and description of various English sites of historical interest by way of the experiences of 'two eager young Americans'.
