“This cable was eight inches in diameter. The lower end was doubled on itself to form an eye five feet in diameter. The other end for 25 miles was left free, the wires all being separate and loose with balls of iron attached to their ends. When this end of the cable was tested, a considerable section, by being subjected to repulsion, rose from the ground and assumed a perpendicular position, the loose ends of the wire parting and repelling each other like the hairs on the head of an electrified person. This was what was required and the test was pronounced a perfect success. “Over the south pole of Mars is a mountain some 8,000 feet above the sea level. They found the exact pole not far from the highest part of this mountain which was a lucky circumstance. Here they planted a great steel shaft deep in the hard rock, its end sticking up so as to receive the eye of the cable. A good deal of grading and leveling off of obstructions that stood up above the proposed sweep of the cable, had to be removed. But the largest part of the work was the construction of the circular railway. This railway was built in a circle around the pole and 285 miles distant from it. The diameter of this circle was 570 and the length of the road was 1,791 miles. There were two purposes to be served by this road. A person standing at the pole of Mars cannot see Deimos on account of the bulge or convex surface of the globe. And it is only when he gets 285 miles from the pole that he can look over the bulge and see the little moon. So a rope drawn taut from Deimos to the pole of the planet, would drag on the ground for the 285 miles next the pole, but outside of the 285 miles the line would gradually leave the ground. A large heavy car was made to travel on the railroad to hold up the cable as it swept around. Attached to this car there was to be a train holding the dynamos in which the power was to be turned into electricity.
