Undoubtedly, the King's Bastion is the center of historic military interest in Gibraltar, but the line-wall should be followed along its impregnable front to complete one's conception of the sea defenses of the great fortress. A little farther on is Government House, the quondam convent, which now forms the official residence of the Governor; and farther still the landing-place, known as Ragged Staff Stairs. Then Jumper's Bastion, already mentioned; and then the line of fortification, running outwards with the coast line towards the New Mole and landing-place, returns upon itself, and rounding Rosia Bay trends again southward towards Buena Vista Point. A ring of steel indeed--a coat of mail on the giant's frame, impenetrable to the projectiles of the most terrible of the modern Titans of the seas. The casemates for the artillery are absolutely bomb-proof, the walls of such thickness as to resist the impact of shots weighing hundreds of pounds, while the mighty arches overhead are constructed to defy the explosion of the heaviest shells. As to its offensive armament, the line-wall bristles with guns of the largest caliber, some mounted on the parapet above, others on the casemates nearer the sea-level, whence their shot could be discharged with the deadliest effect at an attacking ship. He who visits Gibraltar is pretty sure, at least if time permits, to visit Algeciras and San Roque, while from farther afield still he will be tempted by Estepona. The first of these places he will be in a hurry, indeed, if he misses; not that the place itself is very remarkable, as that it stands so prominently in evidence on the other side of the bay as almost to challenge a visit. Add to this the natural curiosity of a visitor to pass over into Spanish territory and to survey Gibraltar from the landward side, and it will not be surprising that the four-mile trip across the bay is pretty generally made. On the whole it repays; for though Algeciras is modern and uninteresting enough, its environs are picturesque, and the artist will be able to sketch the great rock-fortress from an entirely new point, and in not the least striking of its aspects.
