Naturally, as one would judge from the title, the lost mine, which proves to be Nat Trevor's rightful inheritance,—occupies much of the interest of the book. But the mine was in the possession of enemies so powerful and wealthy that it taxed the boys' resources to the uttermost to overcome them. How they did so makes absorbing reading.

In this book also, the young motor rangers solve the mystery of the haunted Mexican cabin, and exterminate for all time a strange terror of the mountains which has almost devastated a part of the peninsula.

The Motor Rangers too, have an exciting encounter with Mexican cowboys, which beginning comically, comes very near having a serious termination for all hands. Emphatically "third speed" books.
