I believe it is not necessary to introduce the Motor Boys to most of my readers, as they have made their acquaintance in the previous books of this series. To those, however, who take up this volume without having previously read the ones that go before, I take pleasure in presenting my friends, Jerry, Ned and Bob.
They are booked for quite a long trip, this time; across the continent to the Pacific coast, where they are destined to have some stirring adventures, searching for a mysterious derelict.
