"Wrong," declared Phineas promptly. "Young man, those trucks were made by the Frenchmen. That boat is a dredger which was laid up before you were born, and was built by the same people."

The information caused our hero to open his eyes very wide, for he, like many another individual, had never heard of the French nation in connection with the isthmus of Panama; or if he had, had entirely forgotten the matter. But to a man like Phineas, with all his keenness in the work in which he was taking no unimportant part, it was not remarkable that French efforts on the isthmus were a matter of historical interest to him.

"A man likes to know the ins and outs of the whole affair," he observed slowly, as they trundled along on the car. "There's thousands, I should say, who don't even know why we have decided to build this canal, and thousands more who don't rightly guess what we're going to do with it when it's finished. But Columbus, when he discovered the Bay of Limon round about the year 1497, thought that he had found a short cut across to the East Indies. He didn't cotton to the fact that the isthmus stretches unbroken between the two Americas, and only came to believe that fact when his boats came to a dead end in the bay he had discovered. Cortés sought for a waterway at Mexico, while others hunted round for a channel along the River St. Lawrence, and all with the one idea of making a short passage to the East Indies.

"Then the Straits of Magellan were discovered, while some of those bold Spaniards clambered across the isthmus and set eyes upon the Pacific Ocean. You know what happened? Guess they built and launched ships at Panama, and the conquest of Peru was undertaken, and following it gold and jewels in plenty were brought by mule train from the Pacific to the Atlantic, across from Panama to Colon. So great was the traffic that even in the days of Charles V of Spain the question of an isthmian canal was mooted; for, recollect, Spain drew riches from the Indies as well as from Peru. And now we come to the nineteenth century. America badly wanted an isthmian crossing which would bring her western ports closer to those on the east, and vice versa. A railway seemed to be the only feasible method, and we tackled the job splendidly. That railway was completed in 1855, in spite of an awful climate, and guess it filled the purpose nicely. Just hereabouts came our war, North against South, and, as you can readily understand, there wasn't much chance of canal building.

"Now we come to the Frenchmen, to Ferdinand de Lesseps," said Phineas, pointing out another group of derelict trucks to our hero. "You want to bear in mind that the question of an isthmian canal was always in the air, always attracting the attention of engineering people. Well, de Lesseps had just completed the Suez Canal, connecting the east with the west, and guess he cast his eye round for new fields to conquer. He floated a company in France, and raised a large sum of money. Then he bought out the Isthmian Railway for twenty-five and a half million dollars. You see, he knew that a railway was wanted to carry his plant, and I guess that the fact of having that railway made him decide to build his canal across where we are working. But there was mismanagement. De Lesseps, like many another man, had been spoiled by success, and had lost his usual good judgment. His expenses were awful, and finally, when the money ran out, his company abandoned the undertaking. In eight years he had spent more than three times the amount for the Suez Canal, and had got through some three hundred million dollars. He and his staff left behind them the trucks you see, besides a large amount of other machinery. At this day there's many a French locomotive pulling our dirt trains right here in the Culebra cutting, while his folks set their mark on the soil. They, too, started to cut through at Culebra, and in those eight years did real honest work. But shortage of money ended their labours, and, as I've said, they've left behind these marks of their presence, with rows and rows of graves over at Ancon; for fever played fearful havoc with the workmen. Yes, it was that which gave America her warning, and set our medical folk at work to tidy up this zone and sweep it clear of mosquitoes and fever."

It was all very interesting, and Jim listened most attentively, though, to be sure, every now and then his mind was distracted for a brief instant by some new object to right or left of the line; while from the very beginning the desire to ask one question and to receive information in reply had been present.

"That tale of the French is new to me," he said, "and I hadn't the faintest idea that a canal had been previously attempted. You've said that Spain desired one by means of which to reach the East Indies and so save the long trip round by the Straits of Magellan; how does America stand when all's finished?"

The fingers of Phineas's only usable hand were clenched instantly. Was it likely that a man such as he, who had counted the cost of the undertaking, and knew something of its vastness, would not also have counted the gain?

"What do we get when all's ended?" he cried eagerly. "Guess for that you require a map by rights, though I can tell you something from memory. To begin with, take New York as our important eastern port, and San Francisco as that on the west coast. Of course I know that we have an inter-oceanic railway. But if goods in bulk were shipped, the boat would have to steam right away south, round by Cape Horn and the Straits of Magellan. The Oregon, one of our best battleships, was lying away up in the Pacific when our war with Spain began. She had to steam more than 13,000 miles to reach Key West, and guess a ship wants overhauling after such a long journey, putting aside the risks she ran of capture en route, owing to her isolation. Well now, this isthmian canal will knock the better part of 9000 miles off the route from New York to San Francisco. The English doing business with our firms in that port will have a journey less by 6000 miles, while New York will be closer to the ports of South America by a good 5000 miles. It'll be a shorter journey from Japan or Australia to New York than it is to-day to Liverpool, while there's scarcely a trip from east to west that won't be helped by this canal we're building. Just think of it, Jim! Where this trolley's running there'll be, one of these days, deep water, with bigger ships floating in it than you can dream of now. You and I will have helped to bring about that matter. When we're old we'll be able to tell the youngsters all about it; for America will know then that she owns something valuable. Her people will have had time to grasp its full significance, and guess then the question will not be, as now, 'Where is the Panama Canal? What are our folks doing?' but 'How was America's great triumph accomplished?' My! Ain't I been gassing? Why, there's Gorgona. Hollo, sonny! Pull her up."

They descended from the car promptly, and made for the huge sheds where one portion of the engineering staff undertook the upkeep of the machinery engaged along the whole line of the canal. The friendly official was waiting for them, and very soon Jim's eyes were bulging wide with delight at the sight of the motor drill he was to manage.
