"Stand by the Union" is the fourth of "The Blue and Gray Series." As in the preceding volumes of the series, the incidents of the story are located in the midst of the war of the Rebellion, now dating back nearly thirty years, or before any of my younger readers were born. To those who lived two days in one through that eventful and anxious period, sometimes trembling for the fate of the nation, but always sustained by the faith and the hope through which the final victory was won, it seems hardly possible that so many years have flowed into the vast ocean of the past since that terrible conflict was raging over so large a portion of our now united country. Stand by the Union Though it is said that the South "robbed the 6 cradle and the grave" to recruit the armies of the Confederacy, it is as true that young and old in the North went forth in their zeal to "Stand by the Union," and that many and many a young soldier and sailor who had not yet seen twenty summers endured the hardships of the camp and the march, the broiling suns, and the wasting maladies of semi-tropical seas, fought bravely and nobly for the unity of the land they loved, and that thousands of them sleep their last sleep in unmarked graves on the sea and the land.

These boys of eighteen to twenty, who survived the rain of bullets, shot, and shell, and the hardly less fatal assaults of disease, are the middle-aged men of to-day, and every one of them has a thrilling story to tell. The boys of to-day read with interest the narratives of the boys of thirty years ago, and listen with their blood deeply stirred to the recital of the veteran of forty-five years, or even 7 younger, who brought back to his home only one arm or one leg. 6 7 In his youth the author used to listen to the stories of several aged Revolutionary pensioners, one of whom had slept in the snows of Valley Forge, another who had been confined on board of the Jersey prison-ship, and a third who had been with Washington at the surrender of Cornwallis. Not one lives to-day who fought in the battles of the Revolution; but a multitude of those who trod the battle-fields of the war that was finished twenty-seven years ago have taken their places, and have become as interesting to the present generation as the heroes of former wars were to the fathers and grandfathers of the boys and girls of to-day.
