Excerpt from Duty Trial of a 40, 000, 000 Gal. Duplex Triple Expansion Worthington Pumping Engine: Thesis While a pump is a very simple mechanism and does not seem a very important factor in the world's progress, yet when one stops to enumerate the different occupations that can be car ried on without the aid of a pump in some form or other, he is at once surprised at the smallness of the figure. Were it not for the pump the live - etock on our farms would perish in the summer while the city would never reach any great size until fire would claim it as a victim. It is this wide scope of util ity that has developed the pump into one of the most important of machines, and without it a great handicap would be placed on every industry.
