christ invented the water wheel and spiral pumps and the chinese are credited with having used ased steam for or lifting water the li egyptian wel sweep used in asia even at this late day stands as the prototype ot of the modern centrifugal consisting of a tan like impel lor jer turning hundreds of revolutions a minute by which water is forced to the surface with an economy a swiftness andi a volume that would amaze the engineer ot of ancient days but one does not need to go to egypt or to india or to china or to rome to study the progress made in tile the development of the pump one only has to jump into an automobile drive to the park utah mine at keetley and visit first the new pumping plant of the park utah consolidated mines company and next the ontario mine of this company here one will be able to co contrast n the methods in handling water today and forty years ago and thereby be better ablo able to visualize the development made in the art of vu pumping mammoth I 1 pump
