"There's no chaplain at the post now," said he, one evening after they were engaged, as they were sitting on the porch of her father's cabin in the bright moonlight, discussing plans for the future and building those airy castles in space as lovers are wont; "but I heard from the adjutant yesterday that one had been ordered to Harker from Fort Leavenworth, under an escort of a squadron of the Fifth Cavalry. They will be up in a couple of weeks, and when he arrives we will get married immediately. Eh! darling?" pleadingly continued Jack.

Susie blushingly assented to Hart's importunity, and then he told her that he had saved enough to stock a ranch and build a house; that he proposed to leave the Government employ as soon as they were married, take up a "claim" on the Elkhorn near her father's, so that he would not be separated from her at all, or she from her family. Then Jack, after cautioning Réaume, who had long before given his consent to the proposed match, to keep a sharp lookout for Indians, started about midnight on his lonely ride back to Fort Harker, where he was obliged to be early the next morning.

Jack arrived at the post long before daylight, and went to bed. When he reported to the commanding officer the next morning immediately after guard-mount, he found himself (much to his disgust, now that he was in love) ordered to guide a scouting-party composed of four companies of the Seventh Cavalry, commanded by Col. Keogh, to the region of Pawnee Rock and the Great Bend of the Arkansas, seventy miles to the southwest of Harker, where the Kiowas, under the leadership of the dreaded Chief Sa-tan-ta, had been for the past fortnight successfully raiding the overland coaches and the freight caravans to New Mexico.

SA-TAN-TA.

The command to which Hart was attached remained away, having occasional brushes with the Indians, for several weeks. During its absence the allied tribes had become excessively impudent and threatening. They culminated their atrocities in a most fiendish and cruel massacre of the settlers on Spillman creek, upon the receipt of the news of which the Government determined to inaugurate an extended campaign against them, in which Gen. Sheridan was to take the field in person, with such famous Indian-fighters for his lieutenants as Gens. Sully, Custer, Carr, and others. Consequently all the scouting-parties were called in to their respective stations by courier, to prepare for the impending great conflict.

Of course, the moment Hart returned to Fort Harker he made preparations to leave for the ranch at Twin Mounds and the girl who had so photographed herself on the tablets of his memory. It was early the next morning after his arrival at the post; he had shaved, put on a new suit purchased from the sutler, and otherwise made himself presentable after his long scout. But he had hardly cinched the saddle on Tatonka before an orderly came to the corral and informed him that the commanding officer desired his presence at once. So Jack, with terribly depressed feelings and mentally cursing his luck, mounted his horse and rode slowly up to headquarters, where he found the General standing on the porch waiting to receive him.

"Jack," said he, as the scout dismounted, "I'm awfully sorry to be compelled to call upon you to make another trip right away, when you have just returned from such a long one, but the fact is there's not another scout at the post; they are all away. I want you to start immediately for the Saline. Part of the Fifth Cavalry are en route from Fort Saunders here, and will probably reach the ford northwest of Fort Hays sometime to-day. It is now only six o'clock," looking at his watch; "you can reach there as soon as they do—before, if you start now. So go at once and guide them in. They don't know anything about that country on the river. You remember how terribly broken it is out there. Here are some dispatches you are to give to whomever you find in command;" and he handed the scout a small package of papers.

"All right, sir," replied Hart, as he put the bundle in the breast-pocket of his flannel shirt; "I'm off now, as soon as I go to my quarters for my saddlebags and carbine."

With a sad heart as he cast his eyes on the blue cones of the Twin Mounds, looming up so suggestively of the ranch at their base, Jack left the post in a few minutes after his interview with Gen. Sully, fully mindful of the responsible duty intrusted to him. Hart made excellent time. He was anxious to get back as soon as possible. By two o'clock he had crossed the Saline, and when about three miles the other side of where the handsome little village of Sylvan to-day nestles so picturesquely in the wealth of woods surrounding, he met the troops, to whose commander he reported, and delivered his dispatches. He turned with them to the river, where, as it was now past three, the command went into camp for the night.
