I daily walked over the adjoining country, and there was little difficulty in discovering the origin of M. Mattei's water sources. Upon the heights behind our camp, a plateau of many miles in extent, with an almost imperceptible inclination towards the south-east, received the rainfall, in addition to the subterranean drainage of the hills in the far distance. A great portion of this area was uncultivated, as the sedimentary limestone was generally close to the surface; this was covered with the usual prickly shrubs that some writers have misnamed "heath," together with the highly aromatic herbs that seem to delight in a thirsty soil; among these is a thorny species of wild thyme, that is a favourite food for hares. In some places the soil was red, forming a strong contrast to the white surface around, and in such spots the earth had been already ploughed in preparation for the forthcoming season. The large area at a higher altitude formed an example of a principle that may be accepted as the rule throughout the island. In walking over this extensive surface, there was occasionally a hollow, drum-like sound beneath the feet, denoting subterranean cavities in the porous and soluble strata beneath the harder upper stratum. It was a natural consequence that a substratum impervious to water should form a bed at a certain level to retain the drainage: by tapping this bed at any point, the water would be discovered; but by piercing the surface below this level, the hydraulic pressure would force the water into a running stream. This M. Mattei has accomplished, not as a new invention, but as the application of a rule well known to the Cypriotes from ancient times; and I repeat my argument, that, "the hereditary ability of these people in discovering and utilising springs is a proof that a scarcity of water has been a chronic difficulty in this island from remote periods, and that no important change has been occasioned by the sensational destruction of forests influencing the rainfall," &c., &c., &c. In my opinion, the whole of the now desolate Messaria district may be rendered fruitful and permanently abundant by the scientific employment of a water-power which already exists, although unseen and undeveloped.
