He has but to express consent by the inclination of his head and sirens will blow, turbine engines will operate as they would never operate for anybody else, thousands of tons of shipping will rearrange itself, and even the sea will become less obstreperous and more circumspect in its demeanour, adjusting, if need be, its tides to suit his wishes.

Steam turbine principles and practice.

The pictures of this first steam-turbine show the head and shoulders of a bronze man set over the flaming brands of a wood fire; his metallic lungs are evidently filled with water, for a jet of steam spurts from his mouth and blows against the paddles of a horizontal turbine wheel, which, revolving, sets in motion some crude machinery.

The engines had already been started, and the helicopters had begun to turn, flickering swiftly in their turbine-tubes.

If you take a card that has been cut to a circular shape and cut the edges so that little wings will be made, then blow on this winged edge, the card will revolve with a buzz; the Parsons steam-turbine works in the same way.

Just as a water-wheel is driven by the weight or force of the water striking the blades or paddles of the wheel, so the force of the many jets of steam striking against the little wings makes the wheels of the steam-turbines revolve.

* I left no quarter unremembered, taking a train, no longer of four, but of eight, vehicles, drawn by an electric motor which I re-charged every morning, mostly from the turbine station in St. Pancras, once from a steam-station with very small engine and dynamo, found in the Palace Theatre, which gave little trouble, and once from a similar little station in a Strand hotel.

Sir Charles Parsons (b. 1854), F.R.S., fourth son of the third Earl of Rosse, is the engineer who developed the steam turbine system and made it suitable for the generation of electricity, and for the propulsion of war and mercantile vessels.
