Two lads were standing in one of the bastions of a fort looking over the sea. There were neither guards nor sentinels there. The guns stood on their carriages, looking clean and ready for action, but this was not the result of care and attention, but simply because in so dry a climate iron rusts but little. A close examination would have shown that the wooden carriages on which they stood were so cracked and warped by heat that they would have fallen to pieces at the first discharge of the guns they upheld. Piles of cannon-balls stood between the guns, half-covered with the drifting sand, which formed slopes half-way up the walls of the range of barracks behind, and filled up the rooms on the lower floor. Behind rose the city of Alexandria, with its minarets and mosques, its palaces and its low mud-built huts. Seaward lay a fleet of noble ships with their long lines of port-holes, their lofty masts, and network of rigging. "What do you think of it, Sidi?" "It is wonderful " his companion replied. "How huge they are, what lines of cannon, what great masts, as tall and as straight as palm-trees Truly you Franks know many things of which we in the desert are ignorant. Think you that they could batter these forts to pieces?" The other laughed as he looked round. "One of them could do that now, Sidi, seeing that there is scarce a gun on the rampart that could be fired in return; but were all in good order, and with British artillerists, the whole fleet would stand but a poor chance against them, for while their shot would do but little injury to these solid walls, these cannon would drill the ships through and through, and if they did not sheer off, would sink them." "But why British artillerists, brother, why not our own people?" "Because you have no properly trained gunners. You know how strong Algiers was, and yet it was attacked with success, twice by the French, twice by ourselves, and once by us and the Dutch; but it is a rule that a strongly defended fort cannot be attacked successfully by ships.
