"In The Saddle" is the second of the "Blue and Gray--On Land." In the first volume a New Hampshire family was transplanted to the southern part of one of the Border States just before the breaking out of the Great Rebellion, now happily an event of the somewhat distant past. An attempt is made in that book to describe the condition of the region in the progress of the story; and the material for it was diligently looked up in the records of those stormy times, in those of official character in the archives of the State in which the events transpired, as well as in "The Record of the Rebellion," Congressional Reports, and the multitude of histories, narratives, biographies, and miscellaneous works on the shelves of public and private libraries. The writer believes his material statements are correct, and that the pictures he has given of the disorderly condition of the State of Kentucky, especially in the southern portion, are not overdrawn. The story of the Lyon family introduces two branches of it, both from the same Northern locality, though, unhappily, not of the same way of thinking on the great question of loyalty to the national government and Secession with the South. Plantation life and manners are presented to some extent, as one of the brothers comes into possession of a large estate and half a hundred slaves by the will of a Kentucky member of the Lyon family. The first volume of the series is devoted to the "bringing out" of the loyal element in the county where the plantation is located, in opposition to the more demonstrative secession or neutral sentiment. A Union meeting in a schoolhouse, disturbed by the "ruffians," as they had come to be called, in which the loyal citizens vigorously defend themselves, and expel the intruders, brings the affairs of the neighborhood to a crisis. The planter is attacked by a mob, and with the assistance of a few of his friends, and by arming a portion of his negroes, successfully encounters the disturbers of the peace. Following these stirring events, two companies of cavalry are enlisted by an authorized officer, carefully drilled, and put in readiness to take the field.
