Edgar approached this man, and when close to him fired. The shot told, and the man’s right arm fell to his side, his revolver dropping on to the ground.

‘Winged!’ shouted Edgar. ‘Hold on, Yacka!’

But Yacka had let go of the horse and pulled the man out of the saddle. The horse, finding itself free, galloped off, with the bag still fast to the front of the saddle.

The other man, seeing how matters were going, and knowing the loose horse had the bag still fast to the saddle, turned tail and galloped after it.

‘The horses—the horses! Quick, Will!’ said Edgar. ‘We must be after them.’

Will brought up the horses, and they were quickly in the saddle.

‘You keep guard over this fellow, Yacka,’ said Edgar. ‘Don’t let him go.’

For answer Yacka smiled savagely, and gripped the man by the throat so hard that his eyes started from his head.

‘He’s in safe hands,’ said Edgar. ‘Come along, Will, or we shall lose our treasure after all.’

They rode away after the other man and the runaway horse as fast as their nags could carry them.
