"Bully! We're fond of the open--with a town convenient!" Macloud laughed. "I know Rickrose well, we can go down this afternoon and see him. He will be so astonished that we are not seeking a political favor, he will go to the Secretary himself and make ours a personal request. Then we will get the necessary camp stuff, and be right on the job." They had passed the Experiment Station and the Rifle Range, and were rounding the shoal onto the Point, when the trotting of a rapidly approaching horse came to them from the rear. "Suppose we conceal ourselves, and take a look," suggested Macloud. "Here is a fine place." He pointed to some rocks and bushes that lined the roadway. The next instant, they had disappeared behind them. A moment more, and the horse and buggy came into view. In it were two men--of medium size, dressed quietly, with nothing about them to attract attention, save that the driver had a hook-nose, and the other was bald, as the removal of his hat, an instant, showed. "The thieves!" whispered Croyden. "Yes--I'll bet a hundred on it!" Macloud answered. "Greenberry Point seems far off," said the driver--"I wonder if we can have taken the wrong road?" "This is the only one we could take," the other answered, "so we must be right. I wonder what that jay's doing?" he added, with a laugh. "Cussing himself for----" The rest was lost in the noise of the team. "Right, you are!" said Croyden, lifting himself from a bed of stones and vines. "Right, you are, my friend! And if I had a gun, I'd give the Coroner a job with both of you." Macloud looked thoughtful. "It would be most effective," he said. "But could we carry it off cleanly? The law is embarrassing if we're detected, you know." "You're not serious?" said Croyden. "I never was more so," the other answered. "I'd shoot those scoundrels down without a second's hesitation, if I could do it and not be caught." "A trifle unconventional!" commented Croyden. "However, your idea isn't half bad; they wouldn't hesitate to do the same to us." "Exactly! They won't hesitate--and, what's more, they have the nerve to take the chance. That is the difference between us and them." They waited until they could no longer hear the horse's hoof-falls nor the rumble of the wheels. Then they started forward, keeping off the road and taking a course that afforded the protection of the trees and undergrowth. Presently, they caught sight of the two men--out in the open, their heads together, poring over a paper, presumably the Parmenter letter. "It is not as easy finding the treasure, as it was to pick my pocket!" chuckled Croyden. "There's the letter--and there are the men who stole it. And we are helpless to interfere, and they know it. It's about as aggravating as----" He stopped, for want of a suitable comparison. Macloud only nodded in acquiescence.
