seemed that the fresh young Aid with whom the boys had the encounter the day before had in some mysterious way gained charge of the advance. He had graduated into the Engineer Corps from West Point, and here was an opportunity to display his immense knowledge to the glory of himself and the Engineers and the astonishment of those inferior persons who were merely officers of cavalry, infantry and artillery. Now he would show off the shrewd expedients and devices which have embellished the history of military engineering since the days of Hannibal and Julius Cesar.

That everybody might know who was doing all this, the Aid was riding back and forward, loudly commanding parties engaged in various efforts over more than a quarter of a mile of front. He had brought up the pontoon-train, and the pontoniers were having a hard time trying to advance the boats into the rushing waters. It was all that the men could do to hold them against the swift current. If a pole slipped or went down in a deep hole the men holding it would slip and probably fall overboard, the boat would whirl around and drift far out of its place, requiring great labor to bring it back again, and bringing down a torrent of curses from the young Lieutenant on the clumsiness of "the Stoughton bottles" who were pretending to be soldiers and pontoniers. He was feeling that every word of this kind showed off his superior knowledge to those around. Some of the men were standing waist-deep in the water, trying to fasten lines to trees, to hold in place the boats already stationed and being held there by arms straining at the poles. Everywhere those engaged in the work were tumbling down in the water or being carried off their feet by the current and rescued again with difficulty, to be hauled out on the bank, exhausted, soaked to the skin and covered with slimy mud.

For awhile this had seemed funny to the troops waiting to cross, and they had yelled and laughed themselves hoarse at the mishaps of their comrades. Now the fun had all evaporated and everybody was morose, with a strong tendency to outbreaks of profanity.

The old man surveyed the scene with evident satisfaction. "Yo' Yankees will git over thar about the middle o' July," he chuckled. "Now, I reckon that's Goober Crick, an' as I have done seed hit you'll let me go back home, I s'pose, won't ye?"

"That's probably Goober Crick, or at least Goober Crick is somewhere under that muddy freshet," acquiesced Shorty. "But I'm not at all sure that it's the crick. Looks more like a misplaced chunk out o' the Mizzoori River. I'm not sure, either, that your eyes kin see that distance. We'll have to walk you till we find a section of the crick somewhere that kin be recognized by the naked eyes. Come along, and step lively."

The old man groaned, but there was no hope for him from these relentless executants of orders. For a half hour more they plodded on. The mud grew deeper at every step, but the boys mercilessly forced the old man through the worst of it, that they might reach some point where they could actually see Goober Crick. He could not palm off on them any common old mud freshet for a creek that had a regular place on the map.

Finally they came near the pontoons, and saw one almost capsize, throwing everybody in it into the water, while another whirled madly away toward the center of the current, with but one man in, who was frantically trying to stop it and save himself.

"Yes, he'll stop it, much," said Shorty, looking after him. "If he gits ashore before he reaches the Mississippi I'll be surprised. Say, Si, it'll be easier lookin' for Goober Crick in a boat than wading through the mud. Let's git in one o' them boats."

This terrified the old man till he was ready to yield.

"I begin t' know the place," he admitted. "If we take this path through the woods t' the left hit'll bring us out whar yo' kin see Goober Crick for sartin, an' no mistake. Hit's allers above high-water thar."

The boys followed. A very short walk through a curtain of deep woods brought them on to much higher ground, where Goober Creek roared through a narrow channel it had cut in the rocks. As they stood on the banks, Si and Shorty's eyes met in a quick comprehension of the advantages of the place. They looked backward through the woods to see a depression in the hills, which promised a short and comparatively easy cut-off to the road in the rear, where the 200th Ind. lay.

"Yes, this is Goober Crick," said the old man, with an air of recalling an old acquaintance. "I'm sure of hit. Now, you'll let me go home, won't yer? I hain't got a dry thread left on me, an' I know I'll jest fairly die o' rheumatiz."

"Yes, you can go," said Shorty, who was filling his eyes with the lay of the ground, and the chances it offered of getting the 200th Ind. across ahead of the others and gaining the coveted head of the column. "I've no doubt you're awful wet, but mebbe you know more'n you did a couple of hours ago. Skip!"

The old man moved off with alacrity scarcely to be expected of him, and the boys saw that it was wisest to follow him, for he was taking a bee-line through the woods and brush for his home, and that they knew was near where they had left their regiment.

Soon Co. Q, crouching under the cedars and ponchos spread over fence corners, hovering around struggling fires, and sullenly making the best of a very poor prospect, was electrified by Si and Shorty appearing on as near a run as they could put up with their weight-soaked garments.

"Capt. McGillicuddy," gasped Si, "we've found a bully place to cross. Tell the Colonel quick. Let the boys git all the axes and shovels they kin, and come with us. We'll have a crossin' ready by the time the Colonel comes up with the regiment, and we kin git the advance agin."

Si had gained that enviable position in the regiment where he could always have plenty of followers to anything that he proposed. The sullen despondency passed into active alertness as soon as he began speaking, and before he was done some of them were rummaging around the wagons for axes and shovels. Two or three of these implements were found in the old man's yard.

"Go ahead," said the Captain. "I'll speak to the Colonel, and we'll follow you with the regiment. You can get the teams across, too?"

"Certain," said Si, as he handed his gun, cartridge-box, haversack, blanket-roll and overcoat to another boy to carry for him, shouldered his ax and started off at a run, the others following.

They came back to the spot whither the old man had led them. Si's experienced eye quickly selected two tall hickories, which could be felled directly across the stream and form the stringers for his bridge. The next instant the damp air was ringing with the strokes of eight as skillful axmen as there were in the army, Si leading on one tree and Shorty on the other. They could not keep up the feverish pace they had set for many minutes, but the instant their blows relaxed eight other men snatched the axes, and in a few minutes the trees toppled and fell just in the right position. Co. Q was now coming up, followed by the rest of the regiment, and they gave a cheer to echo the crash of the falling trees. Instantly hundreds of men and officers were at work clearing a road and completing the bridge. Some cut down other trees to furnish filling for the approaches, or to split into flooring for the bridge. Some dug down the bank and carried the clay to cover the brush and chunks. In an incredibly short time a bridge was completed, over which the regiment was marched, and the wagons pulled by the men, after the mules had been detached and walked over.

Every fresh success was announced by tremendous cheering, which carried information to the rest of the brigade that the 200th Ind. was doing something unusual. News as to what this was at last reached the ears of the Lieutenant of Engineers, who was continuing his struggle with the pontoons with a persistence worthy of better luck.

He rode up just in time to see Capt. McGillicuddy looking with
