I also learnt that, some fourteen years ago, Doctor Hermann and his man suddenly disappeared from the neighbourhood, and it was said they had gone abroad on a scientific expedition, the house having been denuded of its furniture and left standing empty. From that day to this, no one had occupied the premises. Pursuing my investigations further, I found that at precisely the same time John Temple, the Bradford millionaire, left this country, presumably on a voyage round the world; and enquiries at the great firm of manufacturing engineers in Leeds also revealed the fact that this Harry Graham, their cleverest manager, left their employment to go abroad at the same date. Not one of these persons has been heard of since.
The mystery of all these persons disappearing at the same time, and never being heard of again by mortal man, is now cleared away! I hold the secret, which was flashed to me on the wings of the storm, from boundless space, upon the sands of the Sahara. The following weird and startling story will satisfactorily explain the cause and purpose of these individuals' departure, minutely describe their wonderful and thrilling experiences, and publish to the world the reason why the lonely house on the Yorkshire fells remains tenantless, and is rapidly falling into ruins; and the rich estates of John Temple, cotton lord and millionaire, are still amongst the unclaimed treasures in the jealous keeping of the High Court of Chancery!
The following is in the Doctor's bold and characteristic handwriting.
_Extract from Dr. Hermann's instructions to the finder of the MSS._
"Should these manuscripts chance to fall into the hands of any civilised man, it is my earnest wish, though of German extraction myself, that they should be published--if published at all--in the English tongue. Truth shall prevail, and our return to earth shall scatter, like thistle-down before the autumn winds, the scepticism which I mistake not will encircle them, as soon as man may read them. It is my cherished hope to return to my mother world, and to tell in person of that glorious life and those sublime wonders of a New World. Adieu!"
This brief extract must suffice as introduction. The next chapter will begin at once with the story proper, omitting the uninteresting preliminary portion of the manuscripts.
