Summerlee gave a cry and put his hand to his face, from which the blood was streaming. I felt a prod at the back of my neck, and turned dizzy with the shock. Challenger fell, and as I stooped to pick him up I was again struck from behind and dropped on the top of him. At the same instant I heard the crash of Lord John's elephant-gun, and, looking up, saw one of the creatures with a broken wing struggling upon the ground, spitting and gurgling at us with a wide-opened beak and blood-shot, goggled eyes, like some devil in a medieval picture. Its comrades had flown higher at the sudden sound, and were circling above our heads.
"Now," cried Lord John, "now for our lives!"
We staggered through the brushwood, and even as we reached the trees the harpies were on us again. Summerlee was knocked down, but we tore him up and rushed among the trunks. Once there we were safe, for those huge wings had no space for their sweep beneath the branches. As we limped homewards, sadly mauled and discomfited, we saw them for a long time flying at a great height against the deep blue sky above our heads, soaring round and round, no bigger than wood-pigeons, with their eyes no doubt still following our progress. At last, however, as we reached the thicker woods they gave up the chase, and we saw them no more.
A most interesting and convincing experience," said Challenger, as we halted beside the brook and he bathed a swollen knee.
"We are exceptionally well informed, Summerlee, as to the habits of the enraged pterodactyl."Summerlee was wiping the blood from a cut in his forehead, while I was tying up a nasty stab in the muscle of the neck. Lord John had the shoulder of his coat torn away, but the creature's teeth had only grazed the flesh.
"It is worth noting," Challenger continued, "that our young friend has received an undoubted stab, while Lord John's coat could only have been torn by a bite. In my own case, I was beaten about the head by their wings, so we have had a remarkable exhibition of their various methods of offence.""It has been touch and go for our lives," said Lord John, gravely, "and I could not think of a more rotten sort of death than to be outed by such filthy vermin. I was sorry to fire my rifle, but, by Jove! there was no great choice.""We should not be here if you hadn't," said I, with conviction.
"It may do no harm," said he. "Among these woods there must be many loud cracks from splitting or falling trees which would be just like the sound of a gun. But now, if you are of my opinion, we have had thrills enough for one day, and had best get back to the surgical box at the camp for some carbolic. Who knows what venom these beasts may have in their hideous jaws?"But surely no men ever had just such a day since the world began.
Some fresh surprise was ever in store for us. When, following the course of our brook, we at last reached our glade and saw the thorny barricade of our camp, we thought that our adventures were at an end. But we had something more to think of before we could rest. The gate of Fort Challenger had been untouched, the walls were unbroken, and yet it had been visited by some strange and powerful creature in our absence. No foot-mark showed a trace of its nature, and only the overhanging branch of the enormous ginko tree suggested how it might have come and gone; but of its malevolent strength there was ample evidence in the condition of our stores. They were strewn at random all over the ground, and one tin of meat had been crushed into pieces so as to extract the contents. A case of cartridges had been shattered into matchwood, and one of the brass shells lay shredded into pieces beside it. Again the feeling of vague horror came upon our souls, and we gazed round with frightened eyes at the dark shadows which lay around us, in all of which some fearsome shape might be lurking. How good it was when we were hailed by the voice of Zambo, and, going to the edge of the plateau, saw him sitting grinning at us upon the top of the opposite pinnacle.
"All well, Massa Challenger, all well!" he cried. "Me stay here.
No fear. You always find me when you want."
His honest black face, and the immense view before us, which carried us half-way back to the affluent of the Amazon, helped us to remember that we really were upon this earth in the twentieth century, and had not by some magic been conveyed to some raw planet in its earliest and wildest state. How difficult it was to realize that the violet line upon the far horizon was well advanced to that great river upon which huge steamers ran, and folk talked of the small affairs of life, while we, marooned among the creatures of a bygone age, could but gaze towards it and yearn for all that it meant!
One other memory remains with me of this wonderful day, and with it I will close this letter. The two professors, their tempers aggravated no doubt by their injuries, had fallen out as to whether our assailants were of the genus pterodactylus or dimorphodon, and high words had ensued. To avoid their wrangling I moved some little way apart, and was seated smoking upon the trunk of a fallen tree, when Lord John strolled over in my direction.
"I say, Malone," said he, "do you remember that place where those beasts were?""Very clearly."
"A sort of volcanic pit, was it not?"
"Exactly," said I.
"Did you notice the soil?"
"Rocks."
"But round the water--where the reeds were?"
"It was a bluish soil. It looked like clay.""Exactly. A volcanic tube full of blue clay.""What of that?" I asked.
"Oh, nothing, nothing," said he, and strolled back to where the voices of the contending men of science rose in a prolonged duet, the high, strident note of Summerlee rising and falling to the sonorous bass of Challenger. I should have thought no more of Lord John's remark were it not that once again that night Iheard him mutter to himself: "Blue clay--clay in a volcanic tube!"They were the last words I heard before I dropped into an exhausted sleep.
