William learned that the young man who had first slipped out was Barton, and the man who had done the shooting was Russell. Clark, they said, had taken the steamer for Cape Girardeau, Missouri, two days before, accompanied by a married woman, named Slaughter. The description of the train robbers tallied so well with the appearance of Barton and Russell, that, taking their actions into consideration, there could no longer be any doubt of their complicity in the affair, and it was highly provoking that these two should have escaped. Still, it was an accident which could hardly have been avoided. The fact that the express company would not consent to the employment of a larger force of detectives was the principal cause of this misfortune, for it could have been prevented easily, had William been accompanied by two more good men of my force. As it was, two detectives, dropping unexpectedly upon a nest of five villainous-looking men in the dark, could have hardly hoped to do better than to secure three of them. It could not have been supposed that they would know which were the important ones to capture, especially as they could not distinguish one from another in the uncertain light. Indeed, as afterward appeared, they were fortunate in having escaped alive, for the close approach to fatal wounds, which they both received, showed how deadly had been the intentions of the man Russell, while Burtine had evidently intended that they should never leave the house alive. It may be supposed that the shooting on both sides was none of the best, but it must be remembered that it began without warning, and was over in two minutes. It cannot be expected that snap-shooting, even at close quarters, should be very accurate; yet it was afterward learned that Russell's escape had been about as narrow as William's, two balls having passed through his clothes and grazed his flesh. CHAPTER IV. _The Captured Ruffians are desired for Guides, but dare not join in the Search for the Outlaws.--One of the Robbers is Taken, but subsequently Escapes from the Amateur Detectives.--Another Clue suddenly Fails._ Having searched the whole place, and satisfied himself that the men captured had had no connection with the robbery or the robbers, William offered them one hundred dollars to act as guides through the cane-brake to arrest Barton and Russell. They said they could not if they would, since no man could find his way there in broad daylight, much less at night. They further admitted that they dare not attempt it, as Russell would kill them if they learned of their action. It was now pitch dark, and after a vain attempt to beat through the cane in search of the fugitives, William decided to return to Mr. Merrick's until next day.
