Mr. Basten had yet continued searching and examining the inner grates, when it was discovered by all present that there was a small chip lying on the flat bar of the outer grate, which was supposed to have been there accidently. Mr. Basten, however, being fully satisfied that the inner grate remained secure, was led rather by curiosity, to reach through his hand, and take up the chip that lay on the bar of the outer grate; on doing this, he thought he could perceive that the bar was inclined to hang in a small degree. This led to further examination; and to the utter astonishment of all that were present it was found that the bar was cut one-third off, and artfully concealed with the feather edge of the chip. Our astonishment was increased by the fact that it was impossible to reach the outer grate without first removing the inner. This gave the hint for a more effectual examination, when it was found that he had cut one of the inner bars so neatly, that he could remove and replace it at pleasure, having contrived to conceal the incisions in such a manner as to almost preclude the possibility of detection. There is little or no doubt in two or three nights more he would have effected his second escape, had not his works been discovered, through the very means which, artful as he was, he employed to conceal them. On being asked what instrument he used in cutting the grate, he answered with perfect indifference, “with this saw and file;” and without hesitation handed me from his berth a case-knife, steel-blade, neatly cut in fine teeth, and a common hand saw file. I then asked him how he got to the grates, or whether he had slipped the shackles off his feet? he answered me, no; but that he had cut the chain in the joint of the links, a part where the cut could not very readily be discovered.
