“If we happen to run into old P. D. or his enemy there’s going to be an interesting time of it,” observed Dick. “You don’t say a word about that, Charley, but I know you are thinking about it all the same.”

“And why not?” replied Charley. “Of course I’m thinking about it, but what’s the use talking? We have just got to take our chances. When I’m out on an expedition like this I don’t believe in showing the white feather. It isn’t my style nor yours, either, Dick.”

“If it was mine you bet I wouldn’t be here,” [said] Dick, “but the danger is real just the same.”

“There’s been some one here!” he exclaimed. “Look, Charley, the floor is all tracked over with alkali since we were here.”
