So he turned upon his heel, and a minute later from the deck I could see his short, squat figure bobbing about in the distance as he made his way back to his train.  Well, we are well down Channel now.  There’s the last bell for letters, and it’s good-bye to the pilot.  We’ll be “down, hull-down, on the old trail” from now on.  God bless all we leave behind us, and send us safely back.

CHAPTER VII

“To-morrow we Disappear into the Unknown”

I will not bore those whom this narrative may reach by an account of our luxurious voyage upon the Booth liner, nor will I tell of our week’s stay at Para (save that I should wish to acknowledge the great kindness of the Pereira da Pinta Company in helping us to get together our equipment).  I will also allude very briefly to our river journey, up a wide, slow-moving, clay-tinted stream, in a steamer which was little smaller than that which had carried us across the Atlantic.  Eventually we found ourselves through the narrows of Obidos and reached the town of Manaos.  Here we were rescued from the limited attractions of the local inn by Mr. Shortman, the representative of the British and Brazilian Trading Company.  In his hospital Fazenda we spent our time until the day when we were empowered to open the letter of instructions given to us by Professor Challenger.  Before I reach the surprising events of that date I would desire to give a clearer sketch of my comrades in this enterprise, and of the associates whom we had already gathered together in South America.  I speak freely, and I leave the use of my material to your own discretion, Mr. McArdle, since it is through your hands that this report must pass before it reaches the world.

The scientific attainments of Professor Summerlee are too well known for me to trouble to recapitulate them.  He is better equipped for a rough expedition of this sort than one would imagine at first sight.  His tall, gaunt, stringy figure is insensible to fatigue, and his dry, half-sarcastic, and often wholly unsympathetic manner is uninfluenced by any change in his surroundings.  Though in his sixty-sixth year, I have never heard him express any dissatisfaction at the occasional hardships which we have had to encounter.  I had regarded his presence as an encumbrance to the expedition, but, as a matter of fact, I am now well convinced that his power of endurance is as great as my own.  In temper he is naturally acid and sceptical.  From the beginning he has never concealed his belief that Professor Challenger is an absolute fraud, that we are all embarked upon an absurd wild-goose chase and that we are likely to reap nothing but disappointment and danger in South America, and corresponding ridicule in England.  Such are the views which, with much passionate distortion of his thin features and wagging of his thin, goat-like beard, he poured into our ears all the way from Southampton to Manaos.  Since
