Seeing how thick the fog has come on, the Sardinians may not return here at all." So saying, they hurried to the spot where they had tied up their ponies, and, leading them by the reins, descended into the valley.
"The fog is getting thicker and thicker," Mr.Myers said.

"I cannot see three yards before me.

We must listen for them as they pass, and then join them, although it's by no means impossible that we may be received with a shot." Half an hour passed, and they grew more and more anxious.

Another half-hour, and still no sound was heard.
"I do not think they can possibly have passed without our seeing them, Mr.Archer.The valley is a quarter of a mile wide, but we should be sure to hear the trampling of the horses and the jingling of the sabres." "Yes, sir, I'm sure they have not passed since we got here.

But they may possibly have seen the fog coming on and have ridden rapidly back, and passed before we came down, or they may have gone round by the mouth of the valley parallel to this, which we left to cross into this one." "That is just what I have been thinking." Mr.Myers said.
