I merely observed that in the upper layers, the water was always colder over shallows than in the open sea. On January 25, the ocean being completely deserted, the Nautilus spent the day on the surface, churning the waves with its powerful propeller and making them spurt to great heights. Under these conditions, who wouldn't have mistaken it for a gigantic cetacean?
They slackened their talk and began smacking their lips over ship-biscuit, marmalade, and tea. Still we lay in silence. The screw of the propeller had not started yet. We dared not come out or we would be put ashore. We were hungry. We could hear their tin plates clattering and clinking as the cattlemen ate supper, and smell the smell of cornbeef and boiled potatoes. Our mouths ran from hunger.
Now the shadow paused and turned. Alan had thrown the rudder over and the balloon had responded instantly. The aeroplane arms stretched out horizontally on each side of the car. Ned, reappearing, took a quick look at the altitude gauge and again disappeared. The aeroplane arms dipped in front almost forty-five degrees and the current, blown back by the propeller, struck them with a jar.
Whereupon there ensued a muffled jingling of bells from somewhere down in the liner's interior, and her propeller began to revolve, churning up the water into a frothy swirl about her rudder as she gathered way and began to forge ahead.
The old barquey was certainly steaming ahead at a great rate, the sea coming up before her in a high ridge that nearly topped the fo'c's'le, and welling under her counter on either hand in undulating furrows that spread out beneath her stern in the form of a broad arrow, widening their distance apart as she moved onward, while the space between was frosted as if with silver by the white foam churned up by the ever- whirling propeller blades, beating the water with their rhythmical iteration, thump-thump, thump-thump, thump-thump!
By the afternoon of September 9 we could begin to make our preparations for departure. The engineers had replaced the propeller and tested it; all supplies were on board, and the chronometers had been checked. All that remained was to get rid of the importunate bumboat men who swarmed round the vessel in their little craft, each looking like a small floating shop.
The water about the craft was very muddy and thick now, caused by the propeller stirring up the bottom of the river. "I guess we'll have to wade, or swim, ashore," said Amy, in what she meant to be a cheerful voice. "Never!" cried Grace. "I'll stay here until someone comes for us. Say, we haven't called for help!" she exclaimed, with sudden thought.
That quay was then a wooden one, a fine structure of mighty piles and stringers bearing a roadway a thing of great strength. The ship, as I have said before, stopped moving when some hundred feet from it. Then her engines were rung on slow ahead, and immediately rung off again. The propeller made just about five turns, I should say.
HIGH PROPELLER SPEED IMPORTANT. Furthermore, all things considered, high speed is important in the rotation of the propeller, up to a certain point, beyond which the pull decreases in proportion to the speed. High speed makes a vacuum behind the blade and thus decreases the effective pull of the succeeding blade.
Jim meant to affix his torpedo to the ship's stern-post, so that, if it did not actually sink her, it might at least blow away both rudder and propeller, and so render the ship useless. Arrived at the stern, he saw that she was his old enemy, the Manco Capac, and he at once set to work.
