The Greeks employed the lever, the tackle, and the crane, the force-pump, and the suction-pump. They had discovered that steam could be mechanically applied, though they never made any practical use of steam. In common with other ancients they knew the principle of the mariner's compass. The Egyptians had the water-wheel and the rudimentary blast-furnace.
Thence it would feed itself up into the carbureter of the working engine by a force-pump attached to the engine, as with the gasoline. The boys had just finished putting in the fuel when Mr. Giddings and Bob drove up in the former's automobile. "I expect this is a great day for you young men?" said the publisher, with a smile of greeting to all.
It was but natural that these three dismal failures should find their way to the newspapers and that, in the hysterical condition of modern journalism, they should be flung out to the world at large with all the ostentation of leaded type and panicky scare heads, and that learned editors should discourse knowingly of "the limitations of mentality" and "the well-authenticated cases of the sudden warping of abnormal intelligences resulting in the startling termination of amazing careers," or snivel dismally over "the complete collapse of that imaginative power which, hitherto, had been this detective's greatest asset, and which now, on the principle that however deep a well may be if a force-pump be put into it it must some time suck gravel, seemed to have come to its end."
Marchbanks's great oak staircase, to go up which had been such a privilege for the bidden few. Rough feet would go over it, unbidden, to-night. She met Mrs. Marchbanks at her bedroom door. In the upper story the cook and house-maids were handing buckets now to the men outside. The fine parlor-maid was down in the kitchen at the force-pump, with Olivia and Adelaide to help and keep her at it.
A force-pump, a common old-style fire-engine, was rigged up, the nozzle and hose bound to a huge pile, to equal which the tallest pine Hewn on Norwegian hills, to be the mast Of some great ammiral, were but a wand. The pump was set to work. The water tore through the nostril-pipe, boring a hole with such rapidity that the tall beam dropped into the socket with startling suddenness.
They renewed and increased their labors at the force-pump, and the impetuous torrent came surging about the diver's ears. It served to complete his danger. It sprung the trap in which he lay enclosed. The inflated armor swelled and filled up the crowded spaces. It stiffened out the casing of the helmet to equal the burden of fifty pounds to the square inch, and made it as hard as iron.
He did get up, and went out to taste the freshness of the early air. The young seamen had finished their labor on the quarters, and were at work in the waist. A kind of force-pump, or fire-engine, was attached to the Josephine, to save labor in washing down the decks, and to be used in case of fire below.
The liquid is made by mixing with water, and for large plants and trees is put on with a spray or force-pump that carries the poison to every part of the plant.
Other mechanisms utilized a somewhat different combination of weights, pulleys, and siphons, operated by the expansive power of air, unheated but under pressure, such pressure being applied with a force-pump, or by the weight of water running into a closed receptacle. One such mechanism gives us a constant jet of water or perpetual fountain.
No more fluid issued from the hose, and, with an explosion like that of a gun, the safety valve of the cylinder blew out, and the stream began spurting from the back. "There's no fire there!" shouted the crowd, laughing at the bad luck of the Weedsport crew. "Too bad, old man!" called Bert in sympathy. "If he had my force-pump here, he could put out that fire yet," said Cole.
