A nation that could educate 10,000 automobile mechanics in 60 days might indeed develop 1,000 Diesel engineers in a year. The matter is of too great moment for delay. It touches the interest of everyone. We are in the petroleum age, and how long it will last depends upon our own foresight, inventiveness, and wisdom. Already we are importers of petroleum.
As Dick sat down beside her, he could feel the throb of the diesel motor. It seemed to carry the rhythm of adventure through the walls of the cabin, giving the feeling of the unknown. For a long time there was silence while Dolores held one of Dick's hands for protection. "Dick! We only have one cabin! I'm supposed to stay here with you and I hardly know you!
Some carried ready-loaded cages waiting to be snatched up by hoists. Crane grips came down, and snapped fast on the cages, and lifted them up and up and out of sight. There was a Diesel running somewhere, and a man stood and stared skyward and made motions with his hands, and the Diesel adjusted its running to his signals.
The Diesel oil engine and multitudes of electrical machines stand for the latest word in mechanical invention. The Diesel again, with a host of other internal combustion engines, the electric motors and waterpower plants, and the absence of steam machines, bear witness to the downfall of steam.
The fuel oil used in the Diesel engines for propulsion on the surface is so thoroughly consumed and the exhaust now is so free of oil that an oil film as an indication of submarine proximity is no longer trustworthy.
To burn oil under a boiler and convert it into steam releases but 10 per cent of the thermal units in the oil, whereas if this same fuel oil were used directly in a Diesel engine, 30 to 35 per cent of the power in the oil would be secured. Substitute the internal-combustion engine for the steam boiler and we multiply by three or three and one-half the supply of fuel oil in the United States.
The casks looked like those in which the crude oil for the ship's Diesel engines arrived, and the fact that she was loading them unemptied-he presumed them unemptied seemed to indicate that the pumping plant on the wharf was out of order. The 5.3 p.m. ran, with a stop at Goole, to Doncaster, where the through carriage was shunted on to one of the great expresses from the north.
He grabbed a big valve and gave it a twist; grabbed another and gave it a twist; and another, and one more; and, standing near by, we could hear or thought we could the in-rush of great waters. The Diesel engines, driven by crude petroleum, propel the ship on the surface. A man got to wondering then what would happen if this chap got his valves mixed.
Barney reached for a dipper hanging on a nail beside the kitchen door. Hetty dipped out a small quantity of the milk, sipped, straightened up with a jerk and spewed the milk out into the yard. "Yaawwwk," she spluttered, "that tastes worse 'n Diesel oil." She stirred distastefully at the swirling, flat-looking liquid in the pails and then turned back to the kitchen.
Here it is a Diesel, started by President Wilson by wireless on the opening day, and generating all the direct current used in the palace. Another commanding exhibit is a 20,000 horsepower hydro-electric generator, significant of the modern use of water-power.
