The settlement was divided into four districts, over each of which was placed a watch consisting of three persons, one principal and two subordinate watchmen.  These, being selected from among those convicts whose conduct and character had been unexceptionable since their landing, were vested with authority to patrol at all hours in the night, to visit such places as might be deemed requisite for the discovery of any felony, trespass, or misdemeanor, and to secure for examination all persons that might appear to be concerned therein; for which purpose they were directed to enter any suspected hut or dwelling or to use any other means that might appear expedient.  They were required to detain and give information to the nearest guardhouse of any soldier or seaman who should be found straggling after the taptoo had been beat.  They were to use their utmost endeavours to trace out offenders on receiving accounts of any depredation; and in addition to their night duty, they were directed to take cognizance of such convicts as gamed, or sold or bartered their slops or provisions, and report them for punishment.  A return of all occurrences during the night was to be made to the judge-advocate; and the military were required to furnish the watch with any assistance they might be in need of, beyond what the civil power could give them.  They were provided each with a short staff, to distinguish them during the night, and to denote their office in the colony; and were instructed not to receive any stipulated encouragement or reward from any individual for the conviction of offenders, but to expect that negligence or misconduct in the execution of their trust would be punished with the utmost rigour.  It was to have been wished, that a watch established for the preservation of public and private property had been formed of free people, and that necessity had not compelled us, in selecting the first members of our little police, to appoint them from a body of men in whose eyes, it could not be denied, the property of individuals had never before been sacred.  But there was not any choice.  The military had their line of duty marked out for them, and between them and the convict there was no description of people from whom overseers or watchmen could be provided.  It might, however, be supposed, that among the convicts there must be many who would feel a pride in being distinguished from their fellows, and a pride that might give birth to a returning principle of honesty.  It was hoped that the convicts whom we had chosen were of this description; some effort had become necessary to detect the various offenders who were prowling about with security under cover of the night; and the convicts who had any property were themselves interested in defeating such practices.  They promised fidelity and diligence, from which the scorn of their fellow-prisoners should not induce them to swerve, and began with a confidence of success the duty which they had themselves offered to undertake.
