Matho was exasperated; every obstacle strengthened his wrath, which led him into terrible extravagances. He mentally summoned Salammbô to an interview; then he waited. She did not come; this seemed to him like a fresh piece of treachery,—and henceforth he execrated her. If he had seen her corpse he would perhaps have gone away. He doubled the outposts, he planted forks at the foot of the rampart, he drove caltrops into the ground, and he commanded the Libyans to bring him a whole forest that he might set it on fire and burn Carthage like a den of foxes. Spendius went on obstinately with the siege. He sought to invent terrible machines such as had never before been constructed. The other Barbarians, encamped at a distance on the isthmus, were amazed at these delays; they murmured, and they were let loose. Then they rushed with their cutlasses and javelins, and beat against the gates with them. But the nakedness of their bodies facilitating the infliction of wounds, the Carthaginians massacred them freely; and the Mercenaries rejoiced at it, no doubt through jealousy about the plunder. Hence there resulted quarrels and combats between them. Then, the country having been ravaged, provisions were soon scarce. They grew disheartened. Numerous hordes went away, but the crowd was so great that the loss was not apparent. The best of them tried to dig mines, but the earth, being badly supported, fell in. They began again in other places, but Hamilcar always guessed the direction that they were taking by holding his ear against a bronze shield. He bored counter-mines beneath the path along which the wooden towers were to move, and when they were pushed forward they sank into the holes. At last all recognised that the town was impregnable, unless a long terrace was raised to the same height as the walls, so as to enable them to fight on the same level. The top of it should be paved so that the machines might be rolled along. Then Carthage would find it quite impossible to resist. The town was beginning to suffer from thirst. The water which was worth two kesitahs the bath at the opening of the siege was now sold for a shekel of silver; the stores of meat and corn were also becoming exhausted; there was a dread of famine, and some even began to speak of useless mouths, which terrified every one.
