Whether Uncle Sid had become tired of waiting for Helen or whether he decided that a proper time had elapsed since the invitation had been given, matters not. Late one afternoon, one of the supply wagons delivered him at Ralph's tent.

The flaps of the tent were open and Ralph was there explaining some blue prints to one of his a.s.sistants. He looked up at the sound of the wagon.

"Oh, h.e.l.lo, Captain! I'm mighty glad to see you. I had about given you up."

"Huh!" the old man grunted. "That ain't over complimentary. From what I've heard, you ain't over quick at givin' up what is worth while."

"Give me a chance, Captain. You don't want to believe all that you hear."

"I don't. That's what I'm up here for."

"Now we're even on compliments. Let's call it quits."

Uncle Sid looked up shrewdly.

"Figures and doin' things ain't all that you're quick at." He paused, taking in the a.s.sistant. "Don't mind me. You go on stuffin' that young man. He ain't full yet."

"Just a minute; then I'm yours truly." Ralph devoted a few moments to the "young man" who, having been "stuffed", departed. "How would you like to take a little drive up the line!"

"Just how much is your little?"

"It's fifteen miles to the next camp. If you say so, we will drive up there and stay all night and the next day we can make the dam in the mountains. I think you'll like it, if it isn't too much." Ralph purposely touched up Uncle Sid with his last remark.

"I ain't too old to know when I've got enough an' I ain't bashful at hollerin' about it, either. You just drive on till I holler, unless you get enough before."

Uncle Sid had little to say on the way, but his keen eyes were taking in everything along the line. Ralph's explanations were listened to in silence. Ralph was not slow to note the absorbed interest of his companion, nor the fact that not a word of his explanations was lost. At every gang of men, Ralph was halted by alert foremen, and often he left the team in charge of Uncle Sid while he went forth to untangle some snarled bit of work or to give further directions in advancing it.

The sun was down when they drew up before the camp and surrendered the team to a waiting Mexican.

Uncle Sid glanced at Ralph with a look at once appreciative and cynical.

"The next time you tell me about a place, you just say how long it is, not how far."

"You'll have to excuse me there. You see I know distances, but I can't always say about the time."

Ralph was up the next morning even before the captain who believed in early rising.

"Good morning, Captain. Ready for another trip?"

"I guess so."

"I can tell distance and time all right today. Do you see what you're up against?" Ralph pointed to the towering San Bernardinos. "It's horseback from here and we ought to be there by three o'clock anyway."

At the mouth of the canon, Ralph explained the dam that was being built across the river and the heavy gates that were being put in.

"You see we let the water come from the reservoir as far as this, in its natural bed. If anything should happen along the ca.n.a.l we can shut off the water at this point first. Later, we could shut it off at the reservoir."

Uncle Sid asked a few questions, then they began to climb the steep mountains. They pa.s.sed loaded pack-mules going up and empty trains coming down the trail. In places the trail was a narrow shelf along the face of a nearly perpendicular cliff. Below them ran the river in its narrow gorge, above them gleamed a slender strip of sky cut into ragged edges by towering cliffs. Just as the trail climbed to the edge of the canon it seemed to end against a smooth wall of granite. A sharp turn to the left, and Uncle Sid could not repress an exclamation of awed delight at the scene before him. The trail led out upon a broad terrace. Two hundred feet below, a treeless valley wound out and in among rounded tree-clad domes of granite. Here and there, on either side, stately spires of naked rock thrust up into the sky, the bare brown of their sides striped with bands of dazzling white.

The dam was to be situated between two granite bluffs at the head of the canon. The masonry gatehouses were already the height of the proposed dam. The gates themselves were closed and the valley was a great lake.

The sight was great, awe-inspiring yet peaceful.

"What do you think of it?"

"Who thought of this?" Uncle Sid glanced at Ralph with shrewd eyes.

"It thought itself." Ralph answered evasively. "We are really only doing here what nature herself did and then undid. You can see that this valley was once a great natural lake. The Sangre de Cristo cut through the canon and drained the lake. Now we are putting in a dam and restoring it."

Uncle Sid did not take his eyes from Ralph's impa.s.sive face.

"Young man, there's a lot o' dust around here, but you can't blow it into my eyes, not that way. You can't do it by keepin' still either, any more than 'Lige Berl can by talkin' about it."

Ralph laughed quietly.

"Oh, well, that doesn't matter. We're going to get what we're after and that's the main thing. Let's go down to camp."

They rode down the winding trail that led from the upper terrace. The remainder of the afternoon was spent in an inspection of the work. After supper, their pipes lighted, they sat looking out over the valley.

"Engineering is a great business," Uncle Sid observed meditatively.

"Yes," Ralph a.s.sented, "so is anything, if you push it."

"I guess not." Uncle Sid chuckled. "I ran away to sea when I was twelve years old. My education was got dancin' at a rope's end when the captain's mess didn't sit well on his stomach." Uncle Sid paused, again chuckled. "A rope's end makes a boy mighty observin.'"

"You didn't learn navigation that way, did you?"

"No-o." Uncle Sid pulled meditatively at his pipe. "A rope's end is also mighty stimulatin' to the imagination. It struck me that I had got all I needed. At the same time, I saw old sailors with bald heads an' gray whiskers, still a dancin'. The only difference I could see between them an' the captain was that the captain could squint at the sun through a spygla.s.s with a half moon hitched to it, an' tell the man at the wheel to hold the ship's head nor'-nor'east."

"Then what?"

"Then? Oh, I just got me a nautical almanac and learned to squint too.

The first thing I knew I was mate, then first officer an' by squintin'

long enough I squinted myself on the quarter deck."

Ralph waited a moment, then spoke laughingly.

"I guess my rope's end wasn't so very different from yours, only I had mine in college."

"You didn't run away to college, did you?"

"No, I didn't; but I had a gad flying around my heels, just the same.

After I got out of college, I was engaged as a.s.sistant to a famous hydraulic engineer. He sent me into the mountains to make a preliminary survey. There weren't many men as big as I was when I strapped a level and a transit to my mule's back and started off. I was going to show that old bomb-sh.e.l.l that he'd got a man worth having, and I wasn't going to stop with him either." Ralph paused to give way to a reminiscent chuckle.

"Well! I wish you could have seen those mountains as I saw them. Talk about taking the starch out of a man! Why, Captain, you could have wadded me up and drawn me through a finger ring like one of those Arabian Nights shawls. There were mountains and mountains, and gulches and gulches, precipices and canons, and rushing, yelping torrents that I was to lead over them, or through them or around them, and the old man hadn't given me a suggestion that I could hang a guess on. The more I thought, the more scared I got. I put up a stiff front, or tried to before my men, but all the time I imagined them laughing at me, or cursing me for making them wade that strip of ice water, or break their shins dragging a chain over the slippery rocks. I was thankful when the sun went down, but that didn't last long. Even in my sleep I saw those mountains jiggering and grinning. They moved into places that I had picked out for my line, and away from them when I had abandoned it. I stood it for a week, then I poured out my woes in a long letter to my chief and sent it out by a special messenger."

Ralph again paused. The old man waited for a moment.

"Well?" he asked.
