The man nodded. It seemed very simple, so stated.

"For the rest," continued the doctor, with a certain stateliness of manner, "I order a complete change of scene. This must be for a fortnight at least, if not longer. If the priest-doctor's report—to whom the Examen may be sent—is not satisfactory, it will have to be for longer. The patient must engage in no business that does not honestly interest him."

"May he travel to-night?" asked the Cardinal.

"The sooner the better," said the doctor, rising.

"What is the matter with me?" asked the invalid hoarsely.

"It is a small mental explosion, but it has not affected the mechanism of the brain. There is not, as I have said, a trace of insanity or of loss of balance. I cannot promise that the injury will be repaired; but defects that may follow from this can easily be remedied by study. It simply depends upon yourself, Monsignor, as to in how long you can be at your post again here. As soon as you have learned the threads of business, you will be able to apply yourself as before. I shall look for a report in a fortnight's time at the latest. Good day, your Eminence."

The clocks of London were all striking the single stroke of midnight as the two priests stood on the wind-sheltered platform of the volor, waiting for the start.

To Monsignor Masterman the scene was simply overwhelming. There was hardly a detail that was not new and unfamiliar. From where he stood on the upper deck, grasping the rail before him, his eyes looked out over a luminous city as lovely as fairyland. There were no chimneys, of course (these, he had just learnt, had altogether disappeared more than fifty years ago), but spires and towers and pinnacles rose before him like a dream, glowing against the dark sky, lit by the soft radiance of the streets beneath. To the right, not a hundred yards away, rose Saint Edward's tower, mellowed now to clear orange by the lapse of three-quarters of a century; to the left a flight of buildings, of an architectural design which he did not understand, but which gave him a sense of extreme satisfaction; in front towered the masses of Buckingham Palace as he seemed always to have known it.

The platform of the flying ship on which he stood hung in dock at least three hundred feet high above the roads beneath. He had examined the whole vessel just now from stem to stern, and had found it vaguely familiar; he determined to examine it again presently. There was no gas-bag to sustain it—so much he had noticed—though he could not say whence he had the idea that gas-bags were usual. But it seemed to him as if the notion of airships did carry some faint association to his mind, although far less distinct than that of motor-cars and even trains. He had enquired of his companion an hour or two earlier as they had discussed their journey as to whether they would not go by train and steamer, and had received the answer that these were never used except for very short journeys.
