that it has scraped from its gallery, the well-sinker clears! his tunnel by sending up the contents through thel vertical shafts fifteen yards apart, around the mouth of which a funnel-shaped mound is formed by the dêbrisM 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 thel main line of the proposed aqueduct. It is not una common to find several chains of wells converging! from different localities to the desired water-head, andil as these are at higher levels, a considerable hydraulic power is obtained, sufficient in many instances nc only to fill the tunnels, but to force the water to greater elevation if required. The water-head being thoroughly established, th( sinking of a chain of wells proceeds, and the tunneli are arranged at a given inclination to conduct tr water to the destined spot. This may be many milei distant, necessitating many hundred wells, which maj comprise great superficial changes ; hills that are bore through necessitate deep shafts, and valleys must 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 eigr. miles distant from the first head. The British authorîl ties propose to substitute iron pipes for the preser aqueduct ; but it is to be hoped that the new scher will be an independent and additional work, that wl in no way interfere with the important gift of Chefli Pacha, which has existed for nearly two centuries, and which, if kept in repair, will supply the necessarj volume.
