WHEN THE OBISPO BROKE IN
Let us watch one of the steam shovels at work. You will notice first that it requires two railroad tracks for its operation—the one on which it stands and one by the side on which are the flat cars it is to load. If the material in which it is to work is clay or sand, the shovel track is run close to the side of the hill to be cut away; otherwise the blasters will have preceded it and a great pile of broken rock lies by the side of the track or covering it before the shovel. Perched on a seat which revolves with the swinging arm a man guides the great steel jaws to the point of excavation. A tug at one lever and the jaws begin to bite into the clay, or root around in the rock pile until the toothed scoops have filled the great shovel that, closed, is rather bigger than a boarding house hall bedroom. A tug at another lever and they close. A third lever causes the arm to swing until it comes to a stop above the flat car, then with a roar and a clatter the whole load is dumped. Perhaps then the trouble is just beginning. Once in a while a boulder of irregular shape rolls about threatening to fall to the ground. With almost human intelligence the great rigid arm of the shovel follows it, checking it as it approaches the edge of the car, pushing it back, buttressing it with other stones, so that when the train gets under way it may by no chance fall off. Sometimes you see all this done from a point at which the directing man is invisible and the effect is uncanny.

UNGAINLY MONSTERS OF STEEL WORKING WITH HUMAN SKILL

THE CULEBRA CUT
Dazzling colors combined with its colossal proportions make this man-made gash in nature’s eternal hills a magnificent spectacle. Its fullest glory will soon be dimmed, for the tropic jungle will cover its brilliant hues with a robe of green.
Travelers in Burmah are fond of telling how the trained elephants pile teak lumber, pushing with tusk and pulling with trunk until the beams lie level and parallel to an inch. But marvelous as is the delicacy with which the unwieldy animals perform their work, it is outdone by the miraculous ingenuity with which the inventive mind of man has adapted these monsters of steel to their appointed task. We shall see on the Zone many mechanical marvels, but to my mind the sight of a man, seated placidly in a comfortable chair, and with a touch on levers making a twenty foot steel arm, with a pair of scoops each as big as a hogshead at the end, feel up and down a bit of land until it comes upon a boulder weighing five tons, then pick it up, deposit it on a flat car, and block it around with smaller stones to hold it firm—this spectacle I think will rank with any as an illustration of mechanical genius. It is a pity old Archimedes, who professed himself able to move the world with a lever if he could only find a place for his fulcrum, could not sit a while in the chair of an Isthmian steam shoveler. These men earn from $210 to $240 a month and are the aristocracy of the mechanical force in a society where everybody is frankly graded according to his earnings. They say their work is exceedingly hard upon the nerves, a statement which I can readily credit after watching them at it. Once in a great while they deposit the six-ton load of a shovel on top of some laborer’s head. Incidents of this sort are wearing on their nerves and also upon the physique of the individual upon whom the burden has been laid. On several occasions I timed steam shovels working in the Cut on various sorts of material and found the period occupied in getting a load, depositing it on the car and getting back into position for another bite to be a fraction less than two minutes. According to my observations from five to eight shovel loads filled a car. The car once filled, a big negro wig-wagged the tidings to the engineer who pulled the train ahead the length of one car. The Jamaica negro wig-wagging is always a pleasing spectacle. He seems to enjoy a job as flagman which gives from five to fifteen minutes of calm reflection to each one minute of wagging. Far be it from me to question the industry of these sable Britons by whom the Canal is being built. Their worth in any place, except that of waiters at the Tivoli Hotel, must be conceded. But their specialty is undoubtedly wig-wagging.
