"The weak side of the place is along this sea face. On the other side, the Rock rises right out of the water; but on this side, as you see, it slopes gradually down. There are batteries, all along by the water's edge; but if the place were attacked by a fleet strong enough to knock those batteries to pieces, and silence their guns, a landing could be effected. "At the southern end you see the rocks are bolder, and there is no landing there. That is called Europa Point, and there is a battery there, though you can't make it out, from here." The scene was a very pretty one, and Bob watched it with the greatest interest. A frigate, and two men-of-war brigs, were anchored at some little distance from the Rock; and around them were some thirty or forty merchantmen, waiting for a change in the wind to enable them to sail out through the Straits. White-sailed boats were gliding about among them. At the head of the bay were villages nestled among trees, while the country behind was broken and hilly. On the opposite side of the bay was a town of considerable size, which the captain told him was Algeciras. It was, he said, a large town at the time of the Moors, very much larger and more important than Gibraltar. The ground rose gradually behind it, and was completely covered with foliage, orchards, and orange groves. The captain said: "You see that rock rising at the end of the bay from among the trees, lads. That is called 'the Queen of Spain's Chair.' It is said that, at a certain siege when the Moors were here, the then Queen of Spain took her seat on that rock, and declared she would never go away till Gibraltar was taken. She also took an oath never to change her linen, until it surrendered. I don't know how she managed about it, at last, for the place never did surrender. I suppose she got a dispensation, and was able to get into clean clothes again, some day. "I have heard tell that the Spaniards have a colour that is called by her name--a sort of dirty yellow. It came out at that time. Of course, it would not have been etiquette for other ladies to wear white, when her majesty was obliged to wear dingy garments; so they all took to having their things dyed, so as to match hers; and the tint has borne her name, ever since." "It is a very nasty idea," Bob said; "and I should think she took pretty good care, afterwards, not to take any oaths. It is hot enough, now; and I should think, in summer, it must be baking here." "It is pretty hot, on the Rock, in summer. You know, they call the natives of the place Rock scorpions. Scorpions are supposed to like heat, though I don't know whether they do. You generally find them lying under pieces of loose rock; but whether they do it for heat, or to keep themselves cool, I can't say.
