leaning against another rock while he rolls a cigarette; and then, with his hands in his pockets, he gazes through the smoke at the sky above and the sea on either side, and wonders when he will be paid his peseta a day for fighting and bleeding for his country. This helps to make you understand how six thousand half-starved Englishmen held Gibraltar for four years against the army of Spain. This is about all that you can see of Gibraltar as a fortress. You hear, of course, of much more, and you can guess at a great deal. Up above, where the Signal Station is, and where no one, not even an officer in uniform not engaged on the works, is allowed to go, are the real fortifications. What looks like a rock is a monster gun painted gray, or a tree hides the mouth of another. And in this forbidden territory are great cannon which are worked from the lowest ramparts. These are the present triumphs of Gibraltar. Before they came, the clouds which shut out the sight of the Rock as well as the rest of the world from its summit rendered the great pieces of artillery there as useless in bad weather as they are harmless in times of peace. The very elements threatened to war against the English, and a shower of rain or a veering wind might have altered the fortunes of a battle. But a clever man named Watkins has invented a position-finder, by means of which those on the lowest ramparts, well out of the clouds, can aim the great guns on the summit at a vessel unseen by the gunners lost in the mist above, and by electricity fire a shot from a gun a half-mile above them so that it will strike an object many miles off at sea. It will be a very strange sensation to the captain of such a vessel when he finds her bombarded by shells that belch forth from a drifting cloud. No stranger has really any idea of the real strength of this fortress, or in what part of it its real strength lies. Not one out of ten of its officers knows it. Gibraltar is a grand and grim practical joke; it is an armed foe like the army in _Macbeth_, who came in the semblance of a wood, or like the wooden horse of Troy that held the pick of the enemy's fighting-men. What looks like a solid face of rock is a hanging curtain that masks a battery; the blue waters of the bay are treacherous with torpedoes; and every little smiling village of Spain has been marked down for destruction, and has had its measurements taken as accurately as though the English batteries had been playing on it already for many years. The Rock is undermined and tunnelled throughout, and food and provisions are stored away in it to last a siege of seven years. Telephones and telegraphs, signal stations for flagging, search-lights, and other such devilish inventions, have been planted on every point, and only the Governor himself knows what other modern improvements have been introduced into the bowels of this mountain or distributed behind bits of landscape gardening on its surface.
