I dared not leave the prospector for fear I should never be able to find it again--the shifting sands of the desert would soon cover it, and then my only hope of returning to my Dian and her Pellucidar would be gone forever.
That I ever shall see her again seems but remotely possible, for how may I know upon what part of Pellucidar my return journey may terminate--and how, without a north or south or an east or a west may I hope ever to find my way across that vast world to the tiny spot where my lost love lies grieving for me?
That is the story as David Innes told it to me in the goat-skin tent upon the rim of the great Sahara Desert.
The next day he took me out to see the prospector--it was precisely as he had described it. So huge was it that it could have been brought to this inaccessible part of the world by no means of transportation that existed there--it could only have come in the way that David Innes said it came--up through the crust of the earth from the inner world of Pellucidar.
I spent a week with him, and then, abandoned my lion hunt, returned directly to the coast and hurried to London where I purchased a great quantity of stuff which he wished to take back to Pellucidar with him.
There were books, rifles, revolvers, ammunition, cameras, chemicals, telephones, telegraph instruments, wire, tool and more books--books upon every subject under the sun. He said he wanted a library with which they could reproduce the wonders of the twentieth century in the Stone Age and if quantity counts for anything I got it for him.
I took the things back to Algeria myself, and accompanied them to the end of the railroad; but from here Iwas recalled to America upon important business.
However, I was able to employ a very trustworthy man to take charge of the caravan--the same guide, in fact, who had accompanied me on the previous trip into the Sahara--and after writing a long letter to Innes in which I gave him my American address, I saw the expedition head south.
Among the other things which I sent to Innes was over five hundred miles of double, insulated wire of a very fine gauge.
I had it packed on a special reel at his suggestion, as it was his idea that he could fasten one end here before he left and by paying it out through the end of the prospector lay a telegraph line between the outer and inner worlds.
In my letter I told him to be sure to mark the terminus of the line very plainly with a high cairn, in case Iwas not able to reach him before he set out, so that Imight easily find and communicate with him should he be so fortunate as to reach Pellucidar.
I received several letters from him after I returned to America--in fact he took advantage of every northward-passing caravan to drop me word of some sort.
His last letter was written the day before he intended to depart. Here it is.
My Dear Friend:
Tomorrow I shall set out in quest of Pellucidar and Dian.
That is if the Arabs don't get me. They have been very nasty of late. I don't know the cause, but on two occasions they have threatened my life. One, more friendly than the rest, told me today that they intended attacking me tonight.
It would be unfortunate should anything of that sort happen now that I am so nearly ready to depart.
However, maybe I will be as well off, for the nearer the hour approaches, the slenderer my chances for success appear.
Here is the friendly Arab who is to take this letter north for me, so good-bye, and God bless you for your kindness to me.
The Arab tells me to hurry, for he sees a cloud of sand to the south--he thinks it is the party coming to murder me, and he doesn't want to be found with me. So goodbye again.
Yours,David Innes.
A year later found me at the end of the railroad once more, headed for the spot where I had left Innes.
My first disappointment was when I discovered that my old guide had died within a few weeks of my return, nor could I find any member of my former party who could lead me to the same spot.
For months I searched that scorching land, interviewing countless desert sheiks in the hope that at last I might find one who had heard of Innes and his wonderful iron mole.
Constantly my eyes scanned the blinding waste of sand for the ricky cairn beneath which I was to find the wires leading to Pellucidar--but always was I unsuccessful.
And always do these awful questions harass me when Ithink of David Innes and his strange adventures.
Did the Arabs murder him, after all, just on the eve of his departure? Or, did he again turn the nose of his iron monster toward the inner world? Did he reach it, or lies he somewhere buried in the heart of the great crust?
And if he did come again to Pellucidar was it to break through into the bottom of one of her great island seas, or among some savage race far, far from the land of his heart's desire?
Does the answer lie somewhere upon the bosom of the broad Sahara, at the end of two tiny wires, hidden beneath a lost cairn? I wonder.
