the harbor with its plaything ships; while farther onward, in the same line of vision, the African "Pillar of Hercules," Ceuta, looks down upon the sunlit waters of the Strait. A little farther on is the true highest point of the Rock, 1,430 feet; and yet a little farther, after a descent of a few feet, we come upon the tower known as O'Hara's Folly, from which also the view is magnificent, and which marks the southernmost point of the ridge. It was built by an officer of that name as a watch tower, from which to observe the movements of the Spanish fleet at Cadiz, which, even across the cape as the crow flies, is distant some fifty or sixty miles. The extent, however, of the outlook which it actually commanded has probably never been tested, certainly not with modern optical appliances, as it was struck by lightning soon after its completion. Retracing his steps to the northern end of the height, the visitor historically interested in Gibraltar will do well to survey the scene from here once more before descending to inspect the fortifications of the coast line. Far beneath him, looking landward, lies the flat sandy part of the isthmus, cut just where its neck begins to widen by the British lines. Beyond these, again, extends the zone some half mile in breadth of the neutral ground; while yet farther inland, the eye lights upon a broken and irregular line of earthworks, marking the limit, politically speaking, of Spanish soil. These are the most notable, perhaps the only surviving, relic of the great siege. In the third year of that desperate leaguer--it was in 1781--the Spaniards having tried in vain, since June, 1779, to starve out the garrison, resorted to the idea of bombarding the town into surrender, and threw up across the neutral ground the great earthworks, of which only these ruins remain. They had reason, indeed, to resort to extraordinary efforts. Twice within these twenty-four months had they reduced the town to the most dreadful straits of hunger, and twice had it been relieved by English fleets. In January, 1780, when Rodney appeared in the Straits with his priceless freight of food, the inhabitants were feeding on thistles and wild onions; the hind quarter of an Algerian sheep was selling for seven pounds ten, and an English milch cow for fifty guineas. In the spring of 1781, when Admiral Darby relieved them for the second time, the price of "bad ship's biscuits full of vermin"--says Captain John Drinkwater of the 72nd, an actor in the scenes which he has recorded--was a shilling a pound; "old dried peas, a shilling and fourpence; salt, half dirt, the sweepings of ships' bottoms, and storehouses, eightpence; and English farthing candles, sixpence apiece." These terrible privations having failed to break the indomitable spirit of the besieged, bombardment had, before the construction of these lines, been resorted to. Enormous batteries, mounting 170 guns and 80 mortars, had been planted along the
