Just as night fell we cleared the belt of bamboos, and at once formed our camp, exhausted by the interminable day.
Early next morning we were again afoot, and found that the character of the country had changed once again.
Behind us was the wall of bamboo, as definite as if it marked the course of a river.
In front was an open plain, sloping slightly upwards and dotted with clumps of tree-ferns, the whole curving before us until it ended in a long, whale-backed ridge.
This we reached about midday, only to find a shallow valley beyond, rising once again into a gentle incline which led to a low, rounded sky-line.
It was here, while we crossed the first of these hills, that an incident occurred which may or may not have been important.
Professor Challenger, who with the two local Indians was in the van of the party, stopped suddenly and pointed excitedly to the right.
As he did so we saw, at the distance of a mile or so, something which appeared to be a huge gray bird flap slowly up from the ground and skim smoothly off, flying very low and straight, until it was lost among the tree-ferns.
"Did you see it?" cried Challenger, in exultation.
"Summerlee, did you see it?"
His colleague was staring at the spot where the creature had disappeared.
"What do you claim that it was?" he asked.
"To the best of my belief, a pterodactyl."
Summerlee burst into derisive laughter
"A pter-fiddlestick!" said he.
"It was a stork, if ever I saw one."
Challenger was too furious to speak.
He simply swung his pack upon his back and continued upon his march.
Lord John came abreast of me, however, and his face was more grave than was his wont.
He had his Zeiss glasses in his hand.
"I focused it before it got over the trees," said he.
"I won't undertake to say what it was, but I'll risk my reputation as a sportsman that it wasn't any bird that ever I clapped eyes on in my life."
So there the matter stands.
Are we really just at the edge of the unknown, encountering the outlying pickets of this lost world of which our leader speaks?
I give you the incident as it occurred and you will know as much as I do.
It stands alone, for we saw nothing more which could be called remarkable.
And now, my readers, if ever I have any, I have brought you up the broad river, and through the screen of rushes, and down the green tunnel, and up the long slope of palm trees, and through the bamboo brake, and across the plain of tree-ferns.
At last our destination lay in full sight of us.
When we had crossed the second ridge we saw before us an irregular, palm-studded plain, and then the line of high red cliffs which I have seen in the picture.
There it lies, even as I write, and there can be no question that it is the same.
At the nearest point it is about seven miles from our present camp, and it curves away, stretching as far as I can see.
Challenger struts about like a prize peacock, and Summerlee is silent, but still sceptical.
Another day should bring some of our doubts to an end.
Meanwhile, as Jose, whose arm was pierced by a broken bamboo, insists upon returning, I send this letter back in his charge, and only hope that it may eventually come to hand.
I will write again as the occasion serves.
I have enclosed with this a rough chart of our journey, which may have the effect of making the account rather easier to understand.
CHAPTER IX "Who could have Foreseen it?"
A dreadful thing has happened to us.
Who could have foreseen it?
I cannot foresee any end to our troubles.
It may be that we are condemned to spend our whole lives in this strange, inaccessible place.
I am still so confused that I can hardly think clearly of the facts of the present or of the chances of the future.
To my astounded senses the one seems most terrible and the other as black as night.
No men have ever found themselves in a worse position; nor is there any use in disclosing to you our exact geographical situation and asking our friends for a relief party.
Even if they could send one, our fate will in all human probability be decided long before it could arrive in South America.
We are, in truth, as far from any human aid as if we were in the moon.
If we are to win through, it is only our own qualities which can save us.
I have as companions three remarkable men, men of great brain-power and of unshaken courage.
There lies our one and only hope.
It is only when I look upon the untroubled faces of my comrades that I see some glimmer through the darkness.
