Show f increasing th the bhe e flow of springs it is a well known fact that rain lain water and the water produced by melting snow on high land sinks into the them soil until an impermeable stratum is reached then it follows that stratum as the same tends downward 9 thus producing hubter river rivers bpi bof spi pr brooks when a well is JS dug this thia underground water wate r is sought for but when the water itself comes to the surface then the source is commonly known as a spring in both caseb cases however the water flows along a slope higher e of course at the point of departure than at the point where the water ia Is obtained but during its journey obstacles are often encountered which check the flo fio flow so that sometimes a well can be pumped out much faster than win it will fill hence after every drain upon its resources it lt la Is necessary fp 16 walt waltr r considerable period perlo d in order to allow al lowthe the scanty influx to replace the amount amoun t of water removed such wells frequently dry up uv altogether during the present season beason of the year there is a simple way of increasing the flow of f wells devised sonie some years ago by 14 donet of lyans france ordinarily the mouths of wells are left open hence all along thie the water from flom well dwell to original 8 source there is an equilibrium of I 1 air pres pressure gure sure it donets doneta plan ia Is simply to close the well and pump out some of the air this creates ap an exe excess ass of pressure to drive drivie water into tre the welli thel tha the supply ja thus increased temporarily and at the same i time the underground under ground channels through which which the water passes are enlarged by the bt stronger ronger stream alid and bothe so the supply also becomes permanently augmented in case of a spring however one 4 odthe the principal advantages Is that the water lifts or ought to lift itself to the joyei joyel of osythe the abe soil and arid conse i j w wh ji en on i a pump is n needed then the source is rib jib no better than an ordinary well there is a way lio ho weyer wever of increasing the flow of springs by the aid of a simple siphon which W has been devised by AT CLef Chef debien deblen at the where the spring emerges make an air nir light tank having a aa c clase I 1 p cover ov e into which which insert ins inh 0 r t a pipe p p bend be I 1 rd this thia pipe over and carry it along for a few ht indred hundred feet or BO so until by fbi following lowing the downward trend of the land the end reaches a level say eay six feet lower than that of the spring level jeb JEL Vel now apply a pump and draw water through this tube it thus becomes a siphon the pump is at once removed and the water continues to flow under the influence ofa portion of the atmospheric pres ores pressure surg surd to the differ ente ento e af of level existing between the spring and the lowest end of the tube nil ill chet Chef debien deblen has tried this plan dd ii spring which took twenty four hours ordinarily to fill W a hollow P place a cc in the rock containing about 20 0 quarts from the spring be led a piece of lead ledd pipe four inches in diameter okera overa over a distance of feet so 30 that he obtained adoffer a difference of level 6 of nearly eight feet A watertight and abd airtight iessi dessl vessel was also built on the spring basing so aa as to surround the natural escape orifice this was six years ago during that time the water has run constantly i and instead of yielding quarts per twenty four hours it has giyen given quarts steadily per same sime perl peri periods od that ip the flow hass has by the t above simple expedient been increased nineteen times scientific american |
