Those who were recognised stoutly protested that the warders or detectives were mistaken; they said they had never been in trouble before, and assumed such a virtuous tone of indignation as to somehow shake the faith of their accusers.

An old and astute detective told us that it was not so much the recognising the face and figure of the individual that they depended on in the first instance, as the fact that in nine cases out of ten an “old lag” would betray himself.

Artful as these men are they appear to lose presence of mind the moment the detectives come into the yard.

Those whom they are seeking seem to be but too well aware of the danger that awaits them, and they invariably try to look so perfectly innocent, and slink past in such a shuffling manner, that the chances are they are bound to be “spotted.”

But it must be understood that those who are in search of old acquaintances of this sort generally have a good survey of the prisoners, as they are marching round, from some dark window of the prison before they enter the yard. Thus the bearing and looks of the prisoners are undergoing a careful and rigid scrutiny when they are not aware of it.

On entering, the detectives note any change in their demeanour.

The new man, the green hand, is perfectly indifferent as to who sees him—​indeed, in most cases, he does not even suspect what has brought the crowd of persons into the yard, his natural surmise being, if he reflects at all upon the subject, that they are mere loungers, who have been brought thither from mere idle curiosity.

But with the old hand the case is altogether different. He looks upon the detectives and all prison officials as his natural enemies, and he cannot preserve his usual equanimity when they make their appearance in the exercise-yard, and hence it is that in most cases the old hand, by some sudden or indiscreet movement, is pretty sure to betray himself.

Many culprits of this class would gladly avoid the customary exercise which is deemed requisite by the authorities to take, and Peace was one of this number; but to refuse would only cause them to be looked upon with suspicion, and would be attended with other evil consequences.

When the customary walk-round in the yard is concluded, the general practice at Newgate is for the prisoners to partake of the mid-day meal. This generally consists of a few potatoes or other sort of vegetables, a few ounces of meat, and a tolerably good supply of bread—​the last-named is generally pretty good. Although it is made of coarse flour, still as a rule it is passable enough. When their meat is not included in the list of delicacies soup is given, which is made from the liquor of the meat on the preceding day.
