"The Border Watch" closes the series which began with "The Young Trailers," and which was continued successively in "The Forest Runners," "The Keepers of the Trail," "The Eyes of the Woods," "The Free Rangers," "The Riflemen of the Ohio," and "The Scouts of the Valley." All the eight volumes deal with the fortunes and adventures of two boys, Henry Ware and Paul Cotter, and their friends Shif'less Sol Hyde, Silent Tom Ross and Long Jim Hart, in the early days of Kentucky. The action moves over a wide area, from New Orleans in the South to Lake Superior in the North, and from the Great Plains in the West to the land of the Iroquois in the East.
