Hydraulic machinery; Pumping machinery
It were vain to even try, to trace the advances made toward the mammoth
city pumping stations, from the early beginning hereafter described,
which have inspired the words recorded by J. F. Holloway, M. E.:
“In looking upon the ponderous pumping engines which lift a volume of
water equal to the flow of a river, sending it with each throbbing
beat of their pulsating plungers through the arteries and veins
that now reach out in every direction in our great cities, bringing
health, comfort, cleanliness and protection to every home therein, we
cannot but wonder what is the history of their beginning, what the
process of their evolution out from the crude appliances of long ago.
Just who the first man was, and by what stream he sat gazing on his
parched fields, on which the cloudless skies of the Orient shed no
rain, and where the early rising sun with eager haste lapped up the
dew drops which the more kindly night in pity over his hard lot had
shed, and who, looking on his withering grain stalks on the one side
and the life-giving waters which flowed by on the other, first caught
the inspiring thought that if one could only be brought to the other,
how great would be the harvest, we shall never know. Knowing, as we
do, that such still is the problem that confronts the toiler on the
plains of that far-off Eastern land where man’s necessities first
prompted man’s invention, it does not require a great stretch of the
imagination to conceive of such a situation, and to believe that,
acting on the impulse of the moment, he called his mate, and tying
thongs to the feet of a sheep-skin and standing on either side of the
brook, with alternate swingings of the suspended skin they lifted
the waters of the stream to the thirsty field, making its blanched
furrows to bloom with vegetation, and at the same time introducing to
the world the first hydraulic apparatus ever invented, and certainly
the first hydraulic ram ever used.”
The figures shown on the opening page of this section of the work
represent the very first utensils used for collecting and containing
water. The _gourd or calabash_ was undoubtedly the very first; it was
common among the ancient Romans, Mexicans and Egyptians, and in the
most modern times continues to be in use in Africa, South America and
other warm countries. The New Zealanders possessed _no other vessels_
for holding liquids, and the same remark is applicable to numerous
other savage tribes.
