“Oh,” exclaimed the Aradna; “do it by all means! There is nothing so wonderful as that!”
The Jan touched a small lever. Instantly a shaft of light cut down through the blackness. Far, far below it ended in a patch on the ground. Watson eagerly followed its movements as it searched from side to side, seeking he knew not what. And then—
There was a flash of inverted lightning, a flame of white fire, a blinding, stabbing scintillation of a million coruscations. Watson clapped a hand to his eyes, to cut off the sight. It was stunning.
“What is it?” he cried.
“Carbon,” answered the Geos, calmly.
“Carbon! You mean—diamond?”
“Yes, my lord. So it interests you? I did not know. Later you shall see it under more favourable conditions.” Then, to the Jan: “Enough.”
Once again they were in darkness. For some minutes silence was again the rule. Watson watched the red dot moving across the indicator, noting its approach to a three cornered figure on one edge. Suddenly there appeared another dot; then another, and another. Some came from below, others from above; presently there were a score moving in close formation.
“They are all here,” said the Jan to the Geos.
The other nodded, and explained to Chick: “It's the Rhamdas and the Crimson guards. The MacPherson is just ahead. We shall arrive in three minutes.”
