It was like nothing he had ever witnessed before.

No wonder that he became anxious and apprehensive.
All at once the dark-red mass seemed to envelope the cattle upon the plain, and these could be seen running to and fro as if affrighted.
Then the two riders disappeared under its dun shadow! Von Bloom rose to his feet, now seriously alarmed.

What could it mean?
The exclamation to which he gave utterance brought little Truey and Totty from the house; and Hans with Jan had now got back with the sheep and goats.

All saw the singular phenomenon, but none of them could tell what it was.

All were in a state of alarm.
As they stood gazing, with hearts full of fear, the two riders appeared coming out of the cloud, and then they were seen to gallop forward over the plain in the direction of the house.
