The first volume of this series is entitled "The Ranch Girls at Rainbow Lodge." "The Ranch Girls' Pot of Gold" is the second volume of the series. The story of the four "Ranch Girls" continues along lines of constantly increasing interest, and the change of scene accomplished in the third volume of the series, "The Ranch Girls at Boarding School," shows them in a new and strange environment. How they bring the ideals and standards of the big open West to the solution of many of their problems in this new field creates a story even more absorbingly interesting than either of its predecessors.
