The headquarters battalion to which these two earnest young soldiers were attached was still stationed at Fort Clowdry. Readers of "Uncle Sam's Boys in the Ranks" are familiar with the circumstances under which Overton and Terry first enlisted at a recruiting office in New York City. These same readers also know how the two young soldiers put in several weeks of steady drilling at a recruit rendezvous near New York, where they learned the first steps in the soldier's strenuous calling. Our readers are also familiar with all the many things that happened during that period of recruit instruction, and how Hal and Noll, while traveling through the Rockies on their way to join their regiment, aided in resisting an attempt by robbers to hold up the United States mail train. Our readers are well aware of all the exciting episodes of that first garrison life, including the life and death fight that Hal Overton had with thieves while he was on sentry duty in officers' row, and of the efforts of one worthless character in the battalion to discredit and disgrace the service of both splendid but new young soldiers.

In the second volume, "Uncle Sam's Boys on Field Duty," our readers were admitted to equally exciting scenes of a wholly different nature. This volume dealt largely with the troops while away in rough country, under practical instruction in the actual duties of soldiers in the field in war time. Just how soldiers learn the grim business of war was most fully set forth in this volume. Among other hosts of entertaining incidents our readers will recall how Hal, on scouting duty, robbed the "enemy's" outpost of rifles, canteens and secured even the corporal's shoes. Some of Hal's and Noll's other brilliant scouting successes are therein told, and it is described how Hal and Noll finally gained the information that resulted in their own side gaining the victory in the mimic campaign. That volume also told how Lieutenant Prescott, aided by Soldiers Hal and Noll, succeeded at very nearly the cost of their lives in arresting a notorious and desperate criminal for the civil authorities, and how all this was done in the most soldier-like manner. It was such deeds as the scouting and the clever arrest that resulted in the appointment of the two chums as corporals. Then there was the affair, while the regulars were on duty in summer encampment with the Colorado National Guard, in which Hal and Noll, acting under impulses of the highest chivalry, got themselves into trouble that came very near to driving them out of the service.

Since the last rousing scenes in and near Denver, something more than a year had passed. It was now the beginning of the fall of the year following when Corporal Hal Overton, with the signal flags under his arm, waited near the parade ground for that other fine young soldier, Corporal Noll Terry.

A year of busy life it had been, though in the main uneventful. Our two young corporals had spent most of their time since in perfecting themselves in the soldier's grim game. They were now looked upon as two of the very finest and staunchest young soldiers in the service.

"Oh, there comes Noll at last," muttered Corporal Overton some minutes later. "And it's high time, too, if he has any regard for the sacredness of a soldier's punctuality. But he's leaving the telegraph office. I wonder if the dear old fellow has been getting any bad news from the home town?"

Corporal Terry, as he came briskly along the smooth, hard walk of a well-kept military post, looked every inch as fine a soldier as his chum. By this time Noll was just as thoroughly in love with all that pertained to the soldier's spirited life as was Overton.

"Think I was never coming?" hailed Noll gayly.

"I began to wonder if you weren't losing sight of the sacredness that is supposed to be attached to a soldier's appointment," said Hal dryly.

"I am afraid I have been so carried away with a new chance that I've treated you just a bit shabbily," Corporal Noll admitted.

"Think no more of it," begged Hal. "I got the flags."
