Phineas promptly gave him the narrative, Harry meanwhile keeping his eyes on Jim. Then, when he learned that our hero had decided to stay on the isthmus, and seek work there, he climbed out of the narrow cab bolted to the side of the digger, dropped lightly to the ground, and, walking straight up to Jim, held out his hand.

"It's men we want here," he said pleasantly. "Guess you're one. Glad to shake hands with an American who's done a good turn for my friend Phineas. What job are you after?"

Jim told him promptly, while he exchanged his handshake vigorously; for he liked the look of this young American, and took to him instantly.

"I'm not sure yet exactly what job I'll ask for," he answered. "Guess I'm ready to take anything that's going; but I was wondering whether you'd give me a lesson on the digger."

"Know anything about engines and suchlike?" asked Harry sharply.

Jim nodded. "Guess I do," he said, with that delightful a.s.surance so common to the Americans. "I've handled engines of many sorts, particularly those aboard ship; and for some months past I've been doing diving."

"Git in there," said Harry, motioning to the cab, "I'll larn you to work this plant inside an hour or two. Then all that's wanted is jest native gumption, gumption, siree, spelt with a big G, 'cos a man ain't no good on these here chugging machines unless he can keep his head cool.

There's times when the digger pulls through the earth quicker than you can think, and when, if you didn't cut off steam, you'd overwind and chaw up all the chain gear. Then the lip of the digger may happen to get hold on a rock that wants powder to shift it, and if there's steam still on, and the engines pulling, you're likely as not to break up some of the fixings, and tip the whole concern over on to its nose. Hop right in; Mr. Barton, I'll see to this here Jim till evening."

CHAPTER V

The Ways of the Steam Digger

To say that Jim could not have been put into better or more capable hands is to tell only the truth. For Harry, the young American operating the steam digger, was one of those eager, hard-working fellows who strive their utmost, who are not satisfied unless they make the very best of a task, and who, given a machine of great power, cause it to produce the biggest results possible, consistent with proper management, and who, unlike some, do not curtail its strength, and limit its output.

"You jest hop up there inside with me," he said, wiping the sweat from his forehead, and tilting his broad sombrero hat backwards a little.

"It'll be close quarters, you bet; but when a chap's learning a job he don't kick at trifles."

Jim obeyed his orders with alacrity. He clambered up into the narrow cab, which was merely a metal framework bolted to the huge, sloping steel girder which may be termed the backbone of the leviathan digger, and seated himself upon a hard wooden seat barely wide enough for one person. Just above his head was a toothed wheel, with another, very much larger, engaging with it. Beside him, causing him to start when he touched it, for it was very hot, were a brace of cylinders, with a lever adjacent for operating the throttle. Right overhead was a roof of split and warped boards, which helped to keep away the rays of the sun; for on this isthmus of Panama the heat is fierce at times, and extremely enervating.

"But, bless you, we don't notice it," said Harry, swarming up after him, and seeing that he had noticed the shelter. "Most all of us wear a big hat. In fact you can say as every white man does. Them dagoes don't; they seem to like the sun, same as the Spaniards. Seen anything of 'em, mate?"

Jim nodded. "Not much," he admitted. "There were a few aboard that ship, and they didn't impress me much. They lost their heads and fought like wild beasts."

"Aye, that's them all over; but they're good 'uns to work once they're set to at it, and know you won't put up with any nonsense. I don't suppose there was ever a part where gangs of them Spaniards works better than they do here, and gives so little trouble. Now and agin there's a rumpus, and the police has to intervene; but it ain't often. See 'em over there."

Jim had been so occupied with his inspection of the giant digger that he had hardly had eyes for his surroundings; but as Harry pointed, he swung round in the cab and surveyed the scene. It was remarkable, to say the least of it. Right behind him lay track on track of metal rails, all running direct towards the Atlantic, and the majority of them on different levels. They seemed to hug various gigantic steps, by which the sides of the huge trench in which the digger was situated ascended to level ground. Hundreds of cars were on these rails, with a little, smoking engine at their heads, and a half-closed-in cab behind. Gangs of European and black labourers were disposed here and there, some breaking up rocks obstructing the tracks, others carrying lengths of double rail track bolted together in readiness to be placed in position, while yet again others were engaged in pouring a liquid into trenches at the side of the cutting. Jim looked puzzled, and Harry laughed outright as he caught a glimpse of his face.

"Gee! It do amuse me when strangers come along," he cried. "Guess this here's an eye-opener. Any fellow can tell what we're doing, and why we're doing it, except the reason for those men and the stuff they're pouring into the trench. Say now, what's it for?"

Jim could not even hazard a guess. It was inexplicable, and seemed, indeed, to be an idiotic proceeding. His face must have shown his thoughts, for Harry burst into a loud guffaw, though, unconsciously, pride again crept into his tones as he answered.

"Guess you ain't the first as thought there was madmen about," he said.

"But all that stuff being put into the trenches is jest part of this almighty scheme. Without it we wouldn't be able to work; for that's a gang from the sanitary corps, and guess they're nosing round most every day. It's their particular job to see as there isn't a place where a mosquito can breed, or where water can easily lay. Ef there's a spot made in purpose to carry away water, same as that 'ere trench, where some of it's bound to lay, why, they spreads kerosene along it, and no self-respecting mosquito'll go near that stuff. It's a terror to 'em.

Guess this Panama zone, stretching five miles either side of the ca.n.a.l line, fairly gives them insects the pip, it's that unhealthy for 'em. As for us, we lives in comfort, and goes on living, which can't be said for others who was here before us. But jest get a grip of that throttle lever, and don't be skeared. Keep cool all the time, and when I cry 'stop', jest jerk it off. She'll come up short jest as ef she was alive, and that's something, seeing as this is a hundred-ton digger. She's able easy to cut her way into well over a thousand cubic yards of dirt in an eight-hours day, and can sling some six hundred double horse loads into them trucks. But we ain't dealin' with horses here. It's machines all the time, machines, and men, I guess, to drive 'em."

It was grand to hear the fellow talk; unconsciously a glow crept into Jim's face. To think that he, by the movement of his ten fingers, and by the use of his own brain, could control such work, and then to remember that every little task accomplished was setting his country nearer the day of triumph. For triumph it must be: America, in spite of the croakings of a few, cannot and will not fail. She may experience setbacks; but she will prevail in the end. Her native determination and the grit of her workers will compel her.

"You can jest see how we're moving," said Harry, placing a hand on a second lever. "This here digger's set up on a truck heavy enough to take it, with its boiler right away at the tail end of the truck, to counterbalance the stuff we're lifting. We're on rails, as you can see, with a second track beside us that holds a spoil train, as we calls the trucks into which we chucks the dirt. Right clear afore us is the ground we're digging, and you're jest going to take a bite fer yerself.

Watch that digger."

Jim cast his eyes upon the huge bucket with its steel cutting lip placed at the end of a secondary beam slanting downwards from the lower part of the main steel girder. Huge chains ran from the upper edge to the tip of the girder, and, as Harry gently pushed his lever, the chains ran out clanking, and the bucket descended till it b.u.mped on to the ground. It was now at the foot of a broken and steep slope some eight feet in height, at the summit of which was the first of that series of big steps ascending to the top of the lock cutting, and accommodating rail tracks.

Indeed a spoil train was crunching along it as he looked, while on half a dozen others trains were to be seen. As to the sloping bank itself, it ran on directly till it came to a dead end, where an army of men were engaged in erecting the lake-end wall of the lock. Behind, it dwindled into other banks, and was lost in the distance.

"Where we started, I guess," said Harry, following his gaze. "First the dredgers got to work, then the steam shovels. You see, we cut deep down in the centre first of all, and then take a step out at either side.

Then, while diggers get to work to cut other steps we go deeper again in the centre. But let's get at this here bank. That bucket's drawn the chains out by its own weight. This here lever controls a brake, and I can stop the bucket at any point; but it's there, ready for digging.

Give her steam, and gently with it. Be ready to cut off if I shout."

Jim moved his lever ever so gently. The proposition was so new to him that he felt somewhat timid of the results; but Harry was as calm as ever. He watched the cutting edge of the bucket dig deep into the bank, while Jim, watching it also, cast an eye upward at the chains where they pa.s.sed over the tip of the girder. Chug! chug! chug! they went, while the ma.s.sive beam trembled; but nothing could stop the irresistible course of the digger. The bucket sheared its way upward through the soil, and in a very little while had accomplished the whole height of the bank; then, its work done, it shot upward, causing the machine to shiver and shake.

"Cut her off," cried Harry, and obedient to the word Jim shoved the lever over.

"Now take a grip of this here lever I've been holding, and pull it to you. Give her steam."

Clank! clank! clank! Jim felt the gears engage as he shifted the lever, and once more opened the throttle of the engine. Now he experienced a new and altogether delightful sensation; for the huge ma.s.s of machinery to which the cab was bolted, and which was situated on the front of the heavy truck carrying the whole apparatus, swung round easily, the loaded bucket well in front and overhead. Harry grinned: it amused him to watch the delight on his pupil's face. But this was not the moment for allowing his attention to become distracted. He kept a careful eye on the bucket, and, a moment later, just as it began to swing over the dirt truck placed on the side track, he pulled a rope, and with a loud clatter the bottom of the bucket banged open and the dirt fell into the truck.

"Stop her!" he shouted, and Jim at once closed his throttle. "This is the boy that works the shutter for us. See here; pull it and give her steam. Watch those two arms to which the bottom of the bucket are bolted. This here gear just overhead works 'em and closes them over the trigger. Gee! If you ain't working this here like an old hand. Now watch it. That bucket's closed, and you've always to remember to close it afore you swing the machine back again to its work, 'cos the edge of the bottom comes low down and would foul the truck. That'd mean a bust up.

Now, round with her. Stop her; get a hold of the brake lever and let her drop."

Confused at first, because of the multiplicity of movements, in an hour Jim was quite at home with the machine. True, he made errors; for instance, he forgot that very important movement to close the bucket, and, as a consequence, though he missed the side of the truck he nearly ripped off the head from a negro. But Harry was there to supervise, and a quick movement on his part arrested the machine.

"Hi! What fo you gwine kill me, yo?" shouted the negro, who had been untouched, as it happened. "Yo take care ob that great big playting ob yours. Not here to dig n.i.g.g.e.rs. Not like hab de head knocked off."

Harry roared. "It's only Joe," he shouted. "He's been as near a blow afore now, and loves to make the most of it. See here, Joe," he bellowed, "I ain't a-goin' to have my machine broken against that 'ere hard head of yours. I'll have to be warning the foreman overseer to shunt yer."

That brought a grin from the negro. He showed his teeth, and shook his fist at Harry; but Jim knew his meaning well enough. The big fellow was just like the rest of his people--just a big, strong, healthy baby, who saw the fun in everything, and, if there were no fun, manufactured it promptly.

"I's gwine to break yo into little pieces," he said, clambering on to the cab and poking his face within an inch of Harry's. "Yo say I hab hard head? Lummy! Me hab hard fist as well."

"Git out!" shouted Harry, striking at him with the slack end of the rope that commanded the bucket trigger.

"Who's he?" demanded Joe, nodding at Jim, and suddenly changing the conversation.

"Him? Why, Jim, of course. Saved Mr. Barton."

"Den I knows him."

To Jim's astonishment the negro stretched out a hand and shook his eagerly. Then he explained the situation. "Know Tom and Sam," he said.

"Dey down here now, seein' tings. I show dem round. Tom mighty impressed: he tink yo work de digger better'n Harry."

That brought an exclamation from the latter, while Joe jumped down from the machine just in time to escape the swing of the rope. But his words were true; close beside the digger were Tom and Sam.

"By de poker, but yo run him well!" shouted Tom. "Me's watched yo dis last half-hour. Seems to Tom as ef yo soon have a job in the diggin'."

To the huge fellow everything that Jim did was well done, everything he attempted was sure to be accomplished; and never for one moment did he tire of watching his hero. But Jim had his lesson to learn, and for another hour held to the work. By that time he had filled a whole spoil train, and had watched another shunted into position.

"Ready to fill like the last," said Harry. "That's the proposition that jest beat us at first. There wasn't enough trucks nor locomotives to begin with, and not enough tracks, so these fine diggers wasted half their time; but we've fixed it a while since. Soon as a train's loaded it's pulled back, while an empty spoil train crosses the switches behind. That comes over another switch just behind the digger, and so right on alongside, the last truck just in position for loading, the first 'way ahead. Then, as you've seen for yourself, we move along, a few inches after every dig, filling the trucks as we go."

"And then?" asked Jim. "What happens? Where is the dirt taken? Who unloads the trucks?"
