What it obviously failed to do was to take account of that additional quarter of a day which really rounds out the actual year. It would have been a vastly convenient thing for humanity had it chanced that the earth had so accommodated its rotary motion with its speed of transit about the sun as to make its annual flight in precisely 360 days.
Frank had read directions how to use this, and he amused himself making a few trials while Jerry was busy. At first he came near pulling a few teeth out, for it is a part of the program that one of the leads must be held between the teeth while others are gathered up in the hands as the net is flung out over the water by a sharp rotary motion that spreads it open as it strikes.
On a somewhat similar principle the unloading of ships laden with grain, ore, coal, and all other articles which can be handled in bulk and divided, will be carried out by machines which, by rotary action, will work their way down to the bottom of the hull and will then be elevated by powerful lifting cranes.
"Bring me another pan," he called, "and more water." He began twisting the bowl with a rotary motion, and when Doc arrived with the pan, nursed the sand out into it, and as the last of the sand went over the lip of the bowl, ran out on deck into the sun, and examined the bottom of the wooden bowl. "Lordy me!" gasped Doc, leaning over Trask's shoulder. "Look at the sparkle!"
Mr. Maudslay was much pleased with the notion, and I speedily put it in action by a close coiled spiral wire of about two feet in length. This was found to transmit the requisite rotary motion to the drill at the end of the spiral with perfect and faithful efficiency. The difficulty was got over, to Mr. Maudslay's great satisfaction.
A half century ago there were no rotary lawnmowers to cut off clover heads; and, if there had been, one could not have been used on these dropping terraces, so populous with slabs and so closely set with turfed mounds and oblongs of early flowering annuals and bedding plants. Mr.
I dashed on in the dark; a wave went over my head as I stooped, nearly waist-deep, groping. His rotary motion, in that smother, made it extremely difficult to obtain any sort of hold. A little more, and he would have knocked my legs from under me, but it was as if my grim determination were by itself of a saving nature. He submitted to being hauled up the beach, passively, like a sack.
There are three principal obstacles to the successful use of such a device: when the submersible is submerged, she employs rotary and not reciprocating prime-movers, being in consequence relatively quiet when running under water, and inaudible at any considerable distance; the noises of the vessel carrying the listening devices are difficult to exclude, as are also the noises of the sea, which are multitudinous; finally, the sound-receiving instruments are not highly directive, hence are not of great assistance in determining the position of the object from which they are receiving sounds.
Such a consummation would be an advantage to all classes concerned. The attempts which have been made in this direction have not as yet proved entirely successful. In the squeezer the glowing ball of white-hot iron is placed, and forced with a rotary motion through a spiral passage, the diameter of which is constantly diminishing.
At last a figure appeared in the cab of the big rotary, looking for a last time at that bleak little section house and the bare flagpole. Then: "Start 'er up and give 'er hell!" Martin was on the job once more, while outside his old section snipes cheered, and reminded him that their hopes and dreams for a division still beloved in spite of a downfall rested upon his shoulders.
