It was a brief and wicked battle, with Jason giving just a little more than he received. Two of the attackers were down and a third holding his cracked head when the weight of numbers carried Jason to the ground. He called to his slaves for aid, then cursed them when they only remained seated, while his arms were pinioned with rope and his weapons stripped from his body. One of the victors waved to the slaves who now stood and docilely marched into the desert. Jason was dragged, snarling with rage, in the same direction. * * * * * There was a wide opening in the desert-facing side of the wall and once through it Jason's anger instantly vanished. Here was one of the _caroj_ that Ijale had told him about: there could be no doubt of it. He could now understand how, to her uneducated eye, there could exist an uncertainty as to whether the thing was an animal or not. The vehicle was a good ten meters long, shaped roughly like a boat, and bore on the front a large and obviously false animal head covered with fur and resplendent with rows of carved teeth and glistening crystal eyes. There were hide coverings and not-too realistic legs hanging about the thing, surely not enough camouflage to fool a sophisticated six-year old. [Illustration] This sort of disguise might be good enough to take in the ignorant savages, but the same civilized child would recognize this as a vehicle as soon as he saw the six large wheels below. They were cut with deep treads and made from some resilient looking substance. No motive power was visible, but Jason almost hooted with joy at the prominent stink of burnt fuel. This crude looking contrivance had some artificial source of power, which might be the product of a local industrial revolution or have been purchased from off-world traders. Either possibility offered the chance of eventual escape from this nameless planet. The slaves, some of them cringing with terror of the unknown, were kicked up the gangplank and into the _caroj_. Four of the huskies who had subdued and bound Jason carried him up and dumped him onto the deck where he lay quietly and examined what could be seen of the desert-vehicle's mechanism. A post projected from the front of the deck and one of the men fitted what could only have been a tiller handle over the squared top of it. If this monolithic apparatus steered with the front pair of wheels it must be driven with the rear, so Jason flopped around on the deck until he could look towards the stern. A cabin, the width of the deck, was situated here, windowless and with a single inset door fitted with a grand selection of locks and bolts. Any doubt that this was the engine room was displaced by the black metal smokestack that rose up through the cabin roof.
