"He sure is a bad egg," said the cowboy, at the end of the recital. "Keep an eye on him by all means." By the time they reached the vicinity of the bridge it was quite dark. Remembering the bad condition of the structure spanning the stream, Sid Todd cautioned Dave to let his horse walk. "Look!" cried the youth, a second later, and pointed around a rise of rocks to the bridge. He had seen two figures leaving the structure. They disappeared behind a high clump of brushwood. "What did you see?" questioned Todd, who had been gazing off to one side of the trail. "Two persons on the bridge. They just ran away into the bushes." "On foot?" "Yes." "Humph! Didn't know anybody was out on foot around here," mused the cowboy. "Sure it wasn't a bear, or some other animal?" And he felt for his horse-pistol. "No, they were men, or boys," answered Dave. "They ran off the bridge the minute we came in sight." "Huh! I wonder if it's possible them hoss-thieves is around again." "Have you horse-thieves in this territory?" "We sure have. Lost two hosses last spring and two last summer. I'll have to tell the boss about seeing them fellows. But maybe--say, hold on, Dave." "What now?" "I may be mistaken, but--don't go on the bridge on hossback." "Why not?" "I'll tell you--after I've examined the bridge," answered Sid Todd, and in a manner that mystified Dave very much. CHAPTER XVI A MEETING ON THE TRAIL Arriving at the bridge, Sid Todd told Dave to halt, and the pair dismounted. As they did so they heard a sound in the bushes beside the stream. They looked in the direction, but saw nobody. The cowboy had drawn his pistol, and with this in hand he walked closer to the bridge. His eyes were on the planking, and presently he uttered an exclamation: "The rascals!" He pointed to two of the planks, and Dave saw that they were loose and so placed that the slightest jar would send them down into the stream. "Do you think those men I just saw did this?" questioned Dave. "Certainly they did! They ought to be hung for it, too!" answered the cowboy, wrathfully. "But what for--to cripple our horses?" "Either that, or to cripple us. Dave, we've got to be on our guard. If those hoss-thieves are watching us----" "I don't think they were horse-thieves, Todd." "You don't? Then----" The cowboy broke off into a low whistle. "Do you mean to say Link Merwell would play such a dirty trick?" "Yes, I do. You haven't any idea how that fellow hates me." "Hum!" mused Sid Todd. "Well, maybe, but I thought it must be the hoss-thieves." "Why would horse-thieves want to hurt our horses?" "They wouldn't want to do that, but they might be thinking our horses would fall and throw us. But I see that reasoning is weak. Maybe it was young Merwell--and Hank Snogger. If it was, they ought to be punished good an' proper, hear me!" went on the cowboy, with emphasis. "I am going to look around the bushes," went on Dave, determinedly.
