On the end of the longer cross-piece is another runner, but this one turns about from side to side with a tiller, like the tiller of a boat that goes in water, and by this the ice boat is steered. Where the two sticks cross the mast is set up, and on this is fastened the sail, and between the sail and the tiller is a sort of shallow box.
To render this the more practicable, they had furnished its wings with spurs in other words, they had left the cross-piece of bamboo to extend on each side about a foot beyond the edge of the paper; and near the end of each extension, they had placed other pieces transversely, and lashed them firmly so that they might act as the flukes of an anchor.
This article was composed of a metal body screwed on to a strong tripod, with a lower tray that moved backwards and forwards, and two lateral buttresses with a steel cross-piece firmly bolted on to them above. Upon this framework were two dynamometers worked by an ingenious piece of mechanism. Juve looked at Charles Rambert and explained. "This is Dr. Bertillon's effraction dynamometer.
They fished it out: a rope was fastened to it by an iron hook, for the board was a float from the mill-wheel. Then they heaved up the rope, which had an anchor at its other end. This also was got in, and on its cross-piece, painted in great letters, there was the name "St. Barbara." Now the whole catastrophe was quite clear.
Another very simple, but effective, device for finding a level line is by means of a triangle of wood made of half-inch boards from 9 to 12 ft. long. To make the legs level, set the triangle up on fairly level ground, suspend a plummet from the top and mark on the cross-piece where the line touches it. Then reverse the triangle, end for end, exactly, and mark the new line the plumb-line makes.
Seated on the cross-piece of a joggling two-wheeled ox cart, moving at the rate of not more than four miles an hour, with a dumb specimen for a driver, and a volume of Baedeker for interpreter and guide, we got our first glimpse of the hideous thing called war. Judging from the looks of the country and the burning villages, we were on the heels of a devastating army.
Its gunwale was hung with horsehair sieves. Up from the thwarts stood many poles, each with cross-pieces, every cross-piece hung with sieves. Its oarsmen edged it nearer and nearer to the Quay and slowed its motion until it was almost stationary opposite the stair, scarcely an arm's-length from the lowest step. When it was close the Emperor spoke to Numisia: "Choose any sieve you see."
We did not use the telescope, but there was scarcely an hour when one or the other of the men was not sitting on a cross-piece up in the dome of the little instrument room, casting a tense, searching gaze through his glasses into the black, starry firmament. A ship might appear at any time now a rescue ship from Earth, or the brigands from Mars.
It was not a very long time, before he had adjusted the first two pegs in their proper places; and, then letting himself off the ladder, and placing both his feet upon the first cross-piece, in a way that they balanced one another and kept the stick in a horizontal position he proceeded to attach the third about the height of his chin.
To that post, about twenty feet from the ground, a cross-piece is attached, to which a rope has been secured, and from that rope a dark object hangs motionless.
