THE papers on the LAST NINETY DAYS OF THE WAR IN NORTH-CAROLINA, which originally appeared in the New-York WATCHMAN, and are now presented in book form, were commenced with no plan or intention of continuing them beyond two or three numbers. The unexpected favor with which they were received led to their extension, and finally resulted in their republication. To do justice to North-Carolina, and to place beyond cavil or reproach the attitude of her leaders at the close of the great Southern States Rights struggle--to present a faithful picture of the times, and a just judgment, whether writing of friend or foe, has been my sole object. Slight as these sketches are, they may claim at least the merit of truth, and this, I am persuaded, is no slight recommendation with the truth-loving people of North-Carolina.
