Ivan protested. He didn't want to go and leave the others behind. But at last he agreed.

"Then I can see no reason for waiting until dark," said Chester. "Let Ivan mount now and make a break for it. We can cover him. They won't get by us. An hour later we can start."

After some further discussion, this plan was adopted; and grumbling somewhat, Ivan mounted in the shelter of the trees. When the Cossack was ready, Hal peered out. A short distance back he could see the pursuers and his appearance drew a shot. But the men were too far away to aim with any degree of accuracy and the shot went wild.

"All right, Ivan," the lad said. "Go!"

The big Cossack dug his heels into his horse's ribs and with a shout dashed out into the road.

There was an answering shout from behind and the thundering of horses' hoofs told those among the trees that the enemy was on the advance.

"We'll have to stop 'em!" cried Hal. "Aim carefully now."

They waited until the riders were close and then stepped into the open.

"Crack! Crack! Crack! Crack!"

The revolvers of the six friends spoke as one. Two of the approaching horsemen reeled in their saddles, then toppled to the ground. Two more dropped their weapons and uttered loud cries. The pursuers beat a hasty retreat.
