When The Wheel Turns The Necklace Of Pots Must Of Necessity Obey The
Movement, And As They Dip Successively And
Fill in the deep water, they
in turn rise to the surface with the revolutions of the wheel; upon
passing
The centre they invert, and empty their contents into a large
trough connected with a reservoir capable of containing many hundred
hogsheads. A circular chain or ladder of twenty feet diameter will
contain about twenty jars of three gallons each--equalling a delivery
of about two and a half gallons per jar, as there is generally a loss of
water during the movement; therefore one complete revolution of the
wheel would deliver fifty gallons into the reservoir.
The wheel is turned by a simple contrivance of wooden cogs and drivers,
worked by a long revolving lever, to which, for a powerful machine such
as I have described, a pair of mules or oxen would be necessary. A child
sits upon the pole or lever and keeps the animals to their work.
There is no specified limit to the depth at which this instrument can
work, as it must depend upon the length of chain and the number of jars,
which of course increase the weight and strain upon the machinery and
animals. In Cyprus, where the water is generally near the surface, the
advantages are obvious, and I feel convinced that no modern invention is
so well adapted for the Cypriote cultivator.
The cost of erection of such a machine complete, together with the
sinking of the pit, is calculated, at an average of localities, as 12
pounds; a pair of oxen will cost 10 pounds: thus the water-wheel in
working order will amount to 22 pounds. One wheel will irrigate eighty
donums, or about forty acres of cereals, but the same instrument would
only suffice for about six acres of garden ground, which requires a more
constant supply of water. It may therefore be understood that in
calculating the power of a water-wheel, various conditions must be
considered, and I shall confine myself to the farm, upon which it will
be necessary to establish one water-wheel or sakyeeah for every forty
acres; this entails a first outlay of eleven shillings per acre; and at
once ensures the crop and renders the farmer independent of the seasons.
But including the cost of constructing the numerous water-channels of
clay to conduct the stream to the desired fields, together with the
expense of erecting the reservoirs of masonry upon a sufficient scale, I
should raise the original outlay for irrigation by cattle-wheels to 20
shillings per acre (1 pound). This would include the services of a pair
of oxen for other work when the sakyeeah should not be required.* (*The
wheel I have described is double the power of those in general use in
Cyprus, where a single animal works the sakyeeah, and it would irrigate
a larger acreage.) According to this calculation, which exceeds by a
large margin the figures given to me by several native farmers, the
owner of a hundred acres must only expend 100 pounds to ensure his
annual crops!
