"We all congratulate you on your wonderful escape, Graham," said Temple. "A bottle of our best port shall be uncorked. It will put new life into you, man."
"And, Graham," remarked the Doctor, "you will perceive that your perilous undertaking has brought about good results. The air we are now breathing is all right again. We have lost but little time, for the moment we knew you were safe the motors were started again at full pressure."
"The leakage," rejoined Graham, addressing the Doctor, "was absurdly trivial, yet it makes one shudder to think what would be the case did our air escape in any larger quantity."
"It only shows how scrupulously careful we must be, and neglect no precautions for our safety," said Temple.
"The perils of our position must keep each one of us alert. Unforeseen terrors may surround us; at any moment we may encounter unknown perils; we may be rushing into the midst of forces that will require all our fortitude to contend against them. We are in the midst of danger, and have to grapple with any difficulty that may present itself, without having the benefit of any human experience to guide us. But we shall pull through; we shall pull through, my friends; and think of our glorious reward!" remarked Doctor Hermann, working himself up into an enthusiastic state of excitement as he spoke.
"What are the results of your observations and calculations to-day, Doctor?" said Graham. "I reckon we are now one million two hundred and fifty thousand miles from home!"
"You were asking me, Graham, about the results I arrived at to-day," continued the Doctor. "Briefly, they may be summarised thus. I find that we are now entirely beyond the attractive forces of the planet, Earth. We are now, as it were, in a neutral position; not yet close enough to Mars to come within the influence of his attraction."
Four hours after the Doctor had thus spoken, that is to say at twenty minutes past two in the afternoon, the transit of Earth commenced. He had timed the occurrence to a second. Slowly the sphere of Earth crept into view, and crossed gradually towards the centre of the sun, and finally passed beyond the disc into space again. No words of human tongue can adequately express the sensations we experienced as we watched the planet Earth, now nothing but a small, dark ball in appearance, travel across the fiery background of the sun. To know that that mere speck was a universe peopled with millions of living creatures--to know that that tiny black disc, so far out yonder, was in reality a vast and mighty world, floating in space, yet so small in comparison to other orbs around us, impressed upon our minds the grand sublimity of Nature's works.
