To prevent the recurrence of any such escape as that just described, it was deemed expedient, in more recent times, to keep a watchman at the top of Newgate. Not many years ago, two men, employed on this duty, quarrelled during the night, and in the morning their bodies were found stretched upon the pavement of the yard beneath. Proceeding along the wall, Jack reached the southern tower, over the battlements of which he clambered, and crossing it, dropped upon the roof of the gate. He then scaled the northern tower, and made his way to the summit of that part of the prison which fronted Giltspur Street. Arrived at the extremity of the building, he found that it overlooked the flat-roof of a house which, as far as he could judge in the darkness, lay at a depth of about twenty feet below. Not choosing to hazard so great a fall, Jack turned to examine the building, to see whether any more favourable point of descent presented itself, but could discover nothing but steep walls, without a single available projection. As he looked around, he beheld an incessant stream of passengers hurrying on below. Lights glimmered in the windows of the different houses; and a lamp-lighter was running from post to post on his way to Snow Hill. Finding it impossible to descend on any side, without incurring serious risk, Jack resolved to return for his blanket, by the help of which he felt certain of accomplishing a safe landing on the roof of the house in Giltspur Street. Accordingly, he began to retrace his steps, and pursuing the course he had recently taken, scaling the two towers, and passing along the wall of the prison, he descended by means of the door upon the Lower Leads. Before he re-entered the prison, he hesitated from a doubt whether he was not fearfully increasing his risk of capture; but, convinced that he had no other alternative, he went on. During all this time, he had never quitted the iron bar, and he now grasped it with the firm determination of selling his life dearly, if he met with any opposition. A few seconds sufficed to clear the passage, through which it had previously cost him more than two hours to force his way. The floor was strewn with screws, nails, fragments of wood and stone, and across the passage lay the heavy iron fillet. He did not disturb any of this litter, but left it as a mark of his prowess. He was now at the entrance of the chapel, and striking the door over which he had previously climbed a violent blow with the bar, it flew open. To vault over the pews was the work of a moment; and having gained the entry leading to the Red Room he passed through the first door; his progress being only impeded by the pile of broken stones, which he himself had raised.
