lastly, upon the lead a vast quantity of mould. The mould was of sufficient depth to let grow very large trees, and such were planted in it, together with other trees, and every description of plant and flower, that was esteemed proper for shrubberies and flower-gardens. To improve all this, there was, on the highest of the terraces, a water-engine, to draw the water out of the river below, wherewith to water the whole garden[113]. Besides all this, there were magazines for corn and provision, capable of maintaining the inhabitants for twenty years; and arsenals, which supplied with arms such a number of fighting men, as seemed equal to the conquest or defence of the whole monarchy. If Babylon was indebted to Nebuchadnezzar for many great buildings, it was still more so to his daughter Nitocris. She erected a great multitude; and amongst the rest, one of the gates. On this gate she caused to be inscribed a command to her successors, that, when she should be buried under it, none of them should open the tomb to touch the treasure which laid there, unless impelled by some great and overwhelming necessity. Many years passed away, and no one opened it. At length Darius came to the city. Reading the inscription, he caused the tomb to be opened; but alas! instead of finding the vast treasures he had expected, he beheld only this inscription:--_"If thou hadst not an insatiable thirst for money, and a most sordid avaricious soul, thou wouldst never have broken open the monuments of the dead."_
