To the economist, then, the island of Menorca must be of interest, but it is infinitely more so to the archæologist. From end to end it is strewn with the works of prehistoric man, whose record in stone is hard to read. These megalithic remains present a strong resemblance to the mirage of Sardinia and Malta, but have also local characteristics which have puzzled and delighted the learned. M. Cartailhac has traced the sites of many ancient villages. The most considerable may be seen at Torre d’ea Galines, south of Alazor. There, on the summit of a slight eminence, a vast pile of stones is all that remains of the “city” to which the naked aborigines fled wildly the instant a sail rose above the horizon. In the constant and arduous struggle waged by the present inhabitants with the stones and the rock, the limits of the stronghold have, ages ago, disappeared, and if it had an outer wall it can no longer be traced. The dwellings were grouped together so closely that no streets can be distinguished. No chariot or beast of burden could have been known to the citizens. They communicated with each other by corridors leading from cabin to cabin. Here and there the doorways remain intact and uphold a heavy lintel of stone. In each of these villages is to be found a single huge monument, composed of two blocks of stone, arranged =T=-shape. It is surrounded by a semicircular wall of unhewn stones, which probably once rose higher and higher and supported a roof of flat stones. These monuments are termed altars by the people of Menorca, and such they may, in fact, have been, but nothing definite can be said on this point. Equally uncertain are the nature and purpose of the monuments called talayots, a word allied to the Arabic term for watch-tower. These are structures of uncemented blocks of stone in the form of a tower, slightly conical or cylindrical, sometimes square at the base. None of them is wholly intact. Whether the summit was a dome or a platform we have no means of knowing. “I observed, however, at Torranba de Salort,” says M. Cartailhac, “a detail which throws some light on this point. The tower is among the highest at the summit and at two steps from the centre lies a great stone more than a metre in diameter, in the shape of a thick mushroom, almost circular, flat on one side and with a protuberance on the other. It is possible that this block once crowned the culminating-point of the edifice.”
