"Mark knows one of his captors understands English or he would have written more; he was only allowed to write what he was told," said Tom.

The Doctor at once wrote the following reply: "Mark, you are to tell them that if one of their number will come with you here he may take away any of the stones we have found."

This answer was written with the object of delay until Burton's return; and, as before, the Doctor took the paper to the salt spring, while Tom went to a position where he could watch the goat carry away the message to the boy; and he had not long to wait, for within a couple of hours the boy and his goats appeared and slowly passed the place, and, as they quietly went along from bush to bush cropping the leaves, one took the letter, and in a few minutes the boy had taken it from the goat.

That night, as soon as it was dark, the mysterious Fakir again entered the cave he had examined a couple of nights previously. He lit his lamp as soon as he was inside, and went straight to the far end.

Here he stood for a time and listened; then he flashed his light up the chimney-shaped opening high above him, the top of which extended far beyond the reach of his light; then, having satisfied himself that all was quiet, he put his arm into a narrow crack in the side of the cave and his fingers grasped two thin ropes; he gave them a sharp jerk, and instantly there was a rustling, swishing noise as a rope-ladder came tumbling down.

The Fakir tugged at the ladder, and, finding that it was securely fastened above, he at once climbed up. When he had gone about forty feet he found the entrance to another passage; but before venturing to explore it he carefully drew up the ladder as it had been before.

The Fakir cautiously made his way, frequently stopping to put his ear to the floor to listen, and keeping a sharp look-out for any side galleries, of which he passed three, but they were much narrower than the one he was following.

He had proceeded about three hundred yards when he suddenly closed the shutter of his lamp; then, after listening a while, he went on in the dark, and it was well he had turned off his light, for the passage took an abrupt turn, and he saw the glimmer of a light in the distance and faintly heard the sound of voices.

Slowly and noiselessly he approached the light, for he concluded it came from some side cave, and this proved to be the case when he had gone a little farther.

"I tell you again that you have got all the stones if, as you say, you have stolen the one Ellison Sahib was taking to Lahore."
