We have a long distance to travel,' said the Angel of Death to our friend Gil, as soon as they had left the Villa. 'I will order my chariot.' And he struck the ground with his foot. A hollow rumbling, like that which precedes an earthquake, sounded under the ground. Presently there rose round the two friends an ash-colored cloud of vapor, in the midst of which appeared a species of ivory chariot, resembling the chariots we see in the bas-reliefs of antiquity. A brief glance would have sufficed (we will not disguise the fact from out readers) to show that the chariot was not made of ivory, but solely and simply of human bones polished and joined together with exquisite skill, but retaining still their natural form. The Angel of Death gave his hand to Gil and they ascended the chariot, which rose into the air like the balloons of the present day, but with the difference that it was propelled by the will of its occupants.
