Time passed on with Edna, measured only by the intervals between the receipt of letters from Mark. These missives were of course frequent and fervid, and responded to in as nearly similar a strain as maidenly reserve would permit. There was nothing particularly novel or striking in Edna's letters, but Mark esteemed them as compositions of wonderful merit. He believed he saw in her well-balanced sentences, and neat, flowing penmanship a reflex of her natty ways and symmetric character. These precious notes he always carried about him, and they were read and re-read until he knew their contents by heart. Edna, on her part, made as absorbing a study of her lover's correspondence. Mark was with the Army of the Potomac in its memorable campaign in the Peninsula. Promotion was rapid among the volunteers, and he was soon advanced to a captaincy. By this time he had been in several engagements, and behaved with credit. Naturally, at his first experience of actual warfare, he was uncertain of himself, and dreaded lest his heart should fail him. The gravity of the commanders at the approach of battle; the sullen boom of distant cannon drawing nearer and nearer--the preliminary pause inspires the novice with dread and awe; but the first flutter of fear over, the sharp crack of rifles and smell of powder soon kindles the blood of a true soldier, and Mark found himself in his element, oblivious of danger, and dashing with the foremost into the fight. He was chary of imparting his own exploits, but Edna heard of them occasionally through the public prints, which she diligently scanned every day for news from the ----th New Jersey Cavalry. Once she had a fearful fright, for she found Captain Mark Gildersleeve's name among the wounded. But, to her relief, a letter from him came soon after, which informed her that the injury he had received was but slight, and that he expected to be in the saddle again in a few days. The truth was, that our hero's career had come within an ace of an untimely close. While out on a reconnaissance, his troop had fallen in with a portion of Jeb Stuart's horse, and Mark, who had often longed for an opportunity for a hand-to-hand combat with some of the noted Southern troopers, drew his sabre and rode with reckless impetuosity into the midst of the enemy. He was about to single out an adversary, as if to engage in a joust, when he was instantly surrounded and a stroke dealt at him which only the stoutness of his leathern cap-visor prevented from terminating his existence. As it was, the gash he received was a serious one; but fortunately his companions had arrived in time to rescue him from further peril, and disperse the rebels. The wound soon healed, but it left a scar which, though it rather impaired his good looks, he deemed a favor for this reason: since he had been in the army he was often subjected to the query, suggested by his lameness, of where and how he had been wounded; the embarrassment of an explanation and the
