But the great range of Phoenicia, its glory and its boast is Lebanon. Lebanon, the “White Mountain"[131]—“the Mont Blanc of Palestine"[132]—now known as “the Old White-headed Man” (Jebel-esh-Sheikh), or “the Mountain of Ice” (Jebel-el-Tilj), was to Phoenicia at once its protection, the source of its greatness, and its crowning beauty. Extended in a continuous line for a distance of above a hundred miles, with an average elevation of from 6,000 to 8,000 feet, and steepest on its eastern side, it formed a wall against which the waves of eastern invasion naturally broke—a bulwark which seemed to say to them, “Thus far shall ye go, and no further.” The flood of conquest swept along its eastern flank, down the broad vale of the Buka’a, and then over the hills of Galilee; but its frowning precipices and its lofty crest deterred or baffled the invader, and the smiling region between its summit and the Mediterranean was, in the early times at any rate, but rarely traversed by a hostile army. This western region it was which held those inexhaustible stores of forest trees that supplied Phoenicia with her war ships and her immense commercial navy; here were the most productive valleys, the vineyards, and the olive grounds, and here too were the streams and rills, the dashing cascades, the lovely dells, and the deep gorges which gave her the palm over all the surrounding countries for variety of picturesque scenery.
The geology of the Lebanon is exceedingly complicated. “While the bulk of the mountain, and all the higher ranges, are without exception limestone of the early cretaceous period, the valleys and gorges are filled with formations of every possible variety, sedimentary, metamorphic, and igneous. Down many of them run long streams of trap or basalt; occasionally there are dykes of porphyry and greenstone, and then patches of sandstone, before the limestone and flint recur."[133] Some slopes are composed entirely of soft sandstone; many patches are of a hard metallic-sounding trap or porphyry; but the predominant formation is a greasy or powdery limestone, bare often, but sometimes
