The difference of soils must also be taken into account. The soil of history on Cape Cod is almost as thin as the physical soil, which is so light and detached that it is blown about by all the winds of heaven. In Sicily, on the other hand, the soil is so much a part of the substance of the island that the sirocco must bring from the shores of Africa the fine particles with which it tortures men. On Cape Cod there are a few colonial traditions, many heroic memories of brave deeds in awful seas, some records of prosperous daring in fishing-ships, and then the advent of the summer colonists; a creditable history, but of so recent date that it has not developed the fructifying power of a rich soil, out of which atmosphere rises like an exhalation. In Sicily, on the other hand, the soil of history is so deep that the spade of the archæeologist has not touched bottom, and even the much-toiling Freeman found four octavo volumes too cramped to tell the whole story, and mercifully stopped at the death of Agathocles. Since the beginning of history, which means only the brief time since we began to remember events, everybody has gone to Sicily, and most people have stayed there until they were driven on, or driven out, by later comers; and almost everybody has been determined to keep the island for himself, and set about it with an ingenuity and energy of slaughter which make the movement toward universal peace seem pallid and nerveless. It is safe to say that on no bit of ground of equal area has more history been enacted than in Sicily; and when Theocritus was young, Sicily was already venerable with years and experience. Now, history, using the word as signifying things which have happened, although enacted on the ground, gets into the air, and one often feels it before he knows it. In this volatile and pervasive form it is diffused over the landscape and becomes atmospheric; and atmosphere, it must be remembered, bears the same relation to air that the countenance bears to the face: it reveals and expresses what is behind the physical features. There is hardly a half-mile of Sicily below the upper ridges of Ætna that has not been fought over; and the localities are few which cannot show the prints of the feet of the gods or of the heroes who were their children.
