Not for the first or second time was he studying this. It had reached him just after his arrival in the country, and the writer thereof was his father.

The latter had been a great traveller in his younger days, and was brimful of Eastern experience; full too, of reminiscence, looking back to perilous years passed among fierce, fanatical races, every day of which represented just so many hours of carrying his life in his hand. Now he was spending the evening of life in peace and quiet. This was the passage which Campian was now studying:

“It came to me quite as a surprise to hear you were in Afghanistan; had I known you thought of going, there are a few things we might have talked over together. I don’t suppose the country is much changed. Oriental countries never do change, any more than their people.

“You remember that affair we have often talked about, when I saved the life of the Durani emir, Dost Hussain, and the story of the hiding of the ruby sword. It—together with the remainder of the treasure—was buried in a cave in a long narrow valley called Kachîn, running almost due east and west. The mountain on the north side is pierced by a very remarkable tangi, the walls of which, could they be closed, would fit like the teeth of a steel trap. I never saw the place myself, but Dost Hussain often used to tell me about it when he promised me half of the buried valuables. I was not particular to go into the subject with him in those days, for I had a strong repugnance to the idea of being paid for saving a man’s life; indeed I used to tell him repeatedly I did not need so costly a gift. But he would not hear of my objections, declaring that when he was able to return for his property half of it should be mine, and I fully believe he would have kept his word, for he was a splendid fellow—more like an Arab that an Asiatic. But Dost Hussain was killed by the Brahuis, and, so far as I was concerned, the secret of the hidden valuables died with him. The only man I know of who shared it was his brother, the Syyed Aïn Asrâf, but he is probably dead, or, at any rate must have recovered it long ago. The sword alone would have been of immense value. I saw it once. Both hilt and scabbard were encrusted with splendid rubies and other stones, but mostly rubies—and there were other valuables.

“It occurs to me that all this must have been hidden somewhere about where you are now, and, if so, you might make a few inquiries. I would like to know whether the sword was ever found or not. Find out if Aïn Asrâf is still alive. If so, he must be very old now. It would be interesting to me to hear how that affair ended, and would give an additional object to your travels...” Then the letter went on to touch upon other matters, and concluded.

As we have said, it was not the first time Campian had pondered over these words, but every time he did so something in them seemed to strike him in a fresh light. Well he remembered hearing his father tell the story by word of mouth, but at such time it had interested him as a story and no more. Now, however, that he was in the very scene of its enactment, it seemed to gain tenfold interest. What if this buried treasure had never been recovered, had lain hidden all these years. The affair dated back to the forties. Afghanistan his father had called it—but this was Afghanistan then. In those days it owned allegiance to the Amir of Kâbul.

A long, narrow valley running almost due east and west! There were many such valleys. And the tangi? Why the very tangi at whose mouth their camp was pitched was the only one cleaving the mountain range on the northern side, and its configuration was exactly that of the one described in his father’s letter. He could not resist a thrill of the pulses. What if this splendid treasure were in reality right under his hand—if he only knew where to lay his hand upon it? There came the rub. The mountain sides here and there were simply honeycombed with caves. To strike the right one without some clue would be a forlorn quest indeed; and he could talk neither Baluch nor Hindustani. The very wildness of the possibility availed to quell any rising excitement to which he might have felt inclined upon the subject; besides, was it likely that this treasure—probably of double value, both on account of its own worth, and constituting a sort of heirloom—would have been allowed to lie buried for forty years or so, and eventually have been forgotten? Somebody or other must have known its hiding place. No; any possibility to the contrary must be simply chimerical.

Just then the “chik” was lifted, and Upward’s head appeared within the tent.

“Can I come in, old chap? Look here, we are all going on a little expedition, so you roll out and come along. There’s a bit of new enclosed forest I want to look at and report on, so we are going to make a picnic of it. There’s a high kotal between cliffs, which gives one a splendid view; then we can go down into the valley, and home again round another way, through a fine tangi which is well worth seeing.”

“I’m right on, Upward. I’ll roll out. Do you mind sending Khola in with the bath?”
