I was weary and spent, so my progress was not so fast as I wished; but at last I came into regions which I knew.  There was the swamp of the pterodactyls upon my left; there in front of me was the glade of the iguanodons.  Now I was in the last belt of trees which separated me from Fort Challenger.  I raised my voice in a cheery shout to allay their fears.  No answering greeting came back to me.  My heart sank at that ominous stillness.  I quickened my pace into a run.  The zareba rose before me, even as I had left it, but the gate was open.  I rushed in.  In the cold, morning light it was a fearful sight which met my eyes.  Our effects were scattered in wild confusion over the ground; my comrades had disappeared, and close to the smouldering ashes of our fire the grass was stained crimson with a hideous pool of blood.

I was so stunned by this sudden shock that for a time I must have nearly lost my reason.  I have a vague recollection, as one remembers a bad dream, of rushing about through the woods all round the empty camp, calling wildly for my companions.  No answer came back from the silent shadows.  The horrible thought that I might never see them again, that I might find myself abandoned all alone in that dreadful place, with no possible way of descending into the world below, that I might live and die in that nightmare country, drove me to desperation.  I could have torn my hair and beaten my head in my despair.  Only now did I realize how I had learned to lean upon my companions, upon the serene self-confidence of Challenger, and upon the masterful, humorous coolness of Lord John Roxton.  Without them I was like a child in the dark, helpless and powerless.  I did not know which way to turn or what I should do first.

After a period, during which I sat in bewilderment, I set myself to try and discover what sudden misfortune could have befallen my companions.  The whole disordered appearance of the camp showed that there had been some sort of attack, and the rifle-shot no doubt marked the time when it had occurred.  That there should have been only one shot showed that it had been all over in an instant.  The rifles still lay upon the ground, and one of them—­Lord John’s—­had the empty cartridge in the breech.  The blankets of Challenger and of Summerlee beside the fire suggested that they had been asleep at the time.  The cases of ammunition and of food were scattered about in a wild litter, together with our unfortunate cameras and plate-carriers, but none of them were missing.  On the other hand, all the exposed provisions—­and I remembered that there were a considerable quantity of them—­were gone.  They were animals, then, and not natives, who had made the inroad, for surely the latter would have left nothing behind.
