Precisely As The Mole Upheaves At Certain Intervals The Earth
That It Has Scraped From Its Gallery, The Well-Sinker Clears His Tunnel
By Sending Up The Contents Through The Vertical Shafts Fifteen Yards
Apart, Around The Mouth Of Which A Funnel-Shaped Mound Is Formed By The
Debris.
These preliminary walls being completed and the water-volume tested, the
neighbourhood is examined with the hope of discovering other springs
that may upon the same principle be conducted towards the main line of
the proposed aqueduct.
It is not uncommon to find several chains of
wells converging from different localities to the desired water-head,
and as these are at higher levels, a considerable hydraulic power is
obtained, sufficient in many instances not only to fill the tunnels, but
to force the water to a greater elevation if required.
The water-head being thoroughly established, the sinking of a chain of
wells proceeds, and the tunnels are arranged at a given inclination to
conduct the water to the destined spot. This may be many miles distant,
necessitating many hundred wells, which may comprise great superficial
changes; hills that are bored through necessitate deep shafts, and
valleys must be spanned by aqueducts of masonry. In this manner the
water is conducted from the springs of Arpera near the spot where the
river issues from the narrow valley among the hills, and supplies
Larnaca, about eight miles distant from the first head. The British
authorities propose to substitute iron pipes for the present aqueduct;
but it is to be hoped that the new scheme will be an independent and
additional work, that will in no way interfere with the important gift
of Cheflik Pacha, which has existed for nearly two centuries, and which,
if kept in repair, will supply the necessary volume.
