There came a sudden, jarring click—like the tapping of iron. And next instant—

The Spot opened to human sight.

The library at 288 Chatterton Place was gone. Instead, the people on the stairs were gazing down from the Spot of Life, straight into the colossal Temple of the Jarados.

It was as Chick had described it—immense—beyond conception. Through the great doors and out into the plaza beyond was gathered all Thomahlia, reverent, like those waiting for the crack of doom.

Above the horde, high on the opposite wall, stood out the monster Clover Leaf of the Jarados; three-coloured—blazing like liquid fire; it was ominous with real life.

At that moment the whole concourse rippled with commotion. Arms were uplifted; one and all pointed towards the dais. They, too were looking through the Spot. Then the multitude began to move.

It heaved and surged and rolled toward the centre. The guards were pressed in upon the Bars, the Bars upon the Rhamda-lined stair. There was no resisting that flood of humanity. On and up it came, sweeping everything before it.

Directly in the foreground lay the snow-stone. On its centre stood the dog Queen, crouching, waiting, bristling. By her side Harry Wendel crouched on one knee, as if awaiting the signal. Behind him, the Nervina, supporting the awakening Aradna. And in front of all, the powerful bulk of Hobart Fenton, standing squarely at the head of the stair, ready to grapple the first to reach the landing.

But most important of all, there stood the doctor himself. He was at the Nervina's side; in his hand, the case of priceless data. He was gazing through the Spot and making a signal of some kind to Watson, whereupon the latter leaped to the edge of the unseen circle.

Something had gone wrong. The Spot was not fully open. Nothing but sight could get through.
