Evans said that for several weeks preceding the Northampton robbery the gang had concealed themselves in the attic of a school-house which stood four or five rods from the highway and apart from other houses. His statement was substantiated by the discovery in this attic, after the robbery, of blankets, satchels, ropes, bits, pulleys, and provisions, including a bottle of whisky bearing the label of a New York firm. After the vault had been rifled, the money and securities were placed in a bag and a pillow-case, and carried to the school-house, where they were stowed away in places of concealment that had been previously prepared. One of these was underneath the platform where the teacher's desk stood. Another was a recess made behind a blackboard, which was taken off for the purpose and then screwed carefully in place. For nearly two weeks this treasure, amounting to over a million dollars, lay unsuspected in the school-house, the teacher walking over a part of it, the children working out their sums on the blackboard which concealed another part. It was left there so long because the robbers were unable to return for it, owing to the strict watch for strangers that was kept at the railway-station and along all the roads. Finally Scott bought a team of horses for nine hundred dollars, and, with Jim Brady, drove over to Northampton from Springfield. After securing the booty, they had serious trouble in getting away. Brady fell into the mill-race, which they were crossing on the ice, and this accident necessitated their camping out all night in a cabin in the woods. After hearing Evans's story, the question foremost in Mr. Pinkerton's mind was where the stolen securities had been concealed. From what Evans said, and from what he knew himself about the methods of the gang, he was satisfied that Dunlap possessed this secret, and would intrust it to no one unless absolutely compelled to do so. The likeliest way of compelling him was to put him under arrest, which might very well be done now that Evans had consented to turn State's evidence. For weeks Pinkerton "shadows" had never been off Scott and Dunlap, who spent most of their time in New York, the former living with his wife at a fashionable boarding-house in Washington Square. Instructions were accordingly given to the "shadows" to close in upon them, and on February 14, 1877, both men were arrested in Philadelphia, as they were on the point of taking a train for the South. Despite the large sum of securities in their possession, the men had run short of ready money, and, while awaiting a compromise, were starting out to commit another robbery. They were taken to Northampton, and committed to jail to await trial.
