The pump was set to work. The water tore through the nostril-pipe, boring a hole with such rapidity that the tall beam dropped into the socket with startling suddenness. Still breathing torrents, the pipe was withdrawn: the clutching sand seized, grappled the stake. It is cemented in. You may break, you may shatter the _stake_, if you will, but--you can never pull it out. Perhaps the most singular and venturesome exploit ever performed in submarine diving was that of searching the sunken monitor Milwaukee during the bay-fight in Mobile harbor. This sea-going fortress was a huge double-turreted monitor, with a ponderous, crushing projectile force in her. Her battery of four fifteen-inch guns, and the tough, insensible solidity of her huge wrought-iron turrets and heavy plated hulk, burdened the sleepy waters of the bay. Upon a time she braced her iron jacket about her, girded her huge sides with fifteen-inch pistolry, and went rolling her clumsy volume down the bay to mash Fort Taylor to rubbish and débacle. The sea staggered under her ponderous gliding and groaned about her massive bulk as she wended her awkward course toward the bay-shore over against the fort. She sighted her blunderbusses, and, rolling, grunting, wheezing in her revolving towers like a Falstaff ill at ease, spat her gobbets of flame and death. The poor little water-spaniel fort ran down to the shore and barked at her of course. _Cui bono_ or _malo?_ Why, like Job's mates, fill its poor belly with the east wind, or try to draw out leviathan with a hook, or his tongue with a cord thou lettest down? Yet who treads of the fight between invulnerable Achilles and heroic Hector, and admires Achilles? The admiral of the American fleet, sick of the premature pother, signaled the lazy solidity to return. The loathly monster, slowly, like a bull-dog wrenched from his victim, rolled snarling, lazily, leisurely down the bay, not obeying and yet not disobeying the signal.
