Thus far we had not observed any signs of intelligent beings on the cloudy globe, and it was still doubtful whether we should not discover it to be a lifeless world.

Our track did not lie exactly on the orbit of the planet, but sufficiently beneath it to let her attraction pull the car up towards her Southern Pole as it passed above us; and by this course of action we trusted to enjoy a wider field of atmosphere to manoeuvre in, and probably a safer descent into a cooler climate than we should have experienced in attempting to land on the equator.

By an illusion familiar in the case of railway trains, it seemed to us that the car was stationary, and the planet rushing towards us.  On it came like a great shield of silver and ebony, eclipsing the stars and growing vaster every moment.  Under the driving force of the engines and the gravity of the planet, our car was falling obliquely towards the orbit, like a small boat trying to cross the bows of an ironclad, and a collision seemed inevitable.  Being on the sunward side we could see more and more of the illuminated crescent as it drew near, and were filled with amazement at the sublime spectacle afforded by the strange contrast between the purple splendour of the solar disc in the black abyss of ether and the pure white celestial radiance which was reflected from the atmosphere of the planet.

The climax of magnificence was reached when the approaching surface came so close as to appear concave, and our little ark floated above a hemisphere of dazzling brightness under a hemisphere of appalling darkness faintly relieved by the glimmer of stars and the purple glory of the sun.

Ere we could express our admiration, however, we were startled by a magical transformation of the scene.  The sky suddenly became blue, the stars vanished from sight, the sun changed to a golden lustre, and the broad day was all around us.

“Whatever has happened?” exclaimed Miss Carmichael between alarm and wonder.

“We have entered the atmosphere of Venus,” responded Gazen with alacrity.  “I wonder if it is breathable?”

So saying he opened one of the scuttles, and a whiff of fresh air blew into the car.  Thrusting his nose out, he sniffed cautiously for a while and then drew several long breaths.

“It seems all right as regards quality,” he remarked, “but there’s too little body in it.  We must wait until we get nearer the ground before we can go outside the car.”

The pressure of the atmosphere as taken by an aneroid barometer confirmed his observation, but as we were ignorant of its average density it could not give us any certain indication of our height.  Far beneath us an ideal world of clouds hid the surface from our view.  We seemed to be floating above a range of snowy Alps, their dusky valleys filled with glaciers, and their sovereign peaks glittering in the sun like diamonds.  As we descended in a long slant, their dazzling summits rose to meet us, and the infinite play of light and shade became more and more beautiful.  The gliding car threw a distinct shadow which travelled along the white screen, and equally to our surprise and delight became fringed with coloured circles resembling rainbows.
