Although only these two instances of extraordinary audacity are specified, others equally bold and daring could be adduced if the limits of this Work would admit of it. When vessels first arrive in the river, particularly those from the West Indies, they are generally very much lumbered. Ships in this situation were considered as the harvest of the River Pirates, with whom it was a general practice to cut away bags of _Cotton_, _Cordage_, _Spars_, _Oars_, and other articles from the quarter of the vessels, and to get clear off, even in the day time as well as in the night. Before a Police existed upon the River all classes of aquatic labourers having been themselves more or less implicated in the same species of criminality, generally connived at the delinquency of each other, and hence it followed, that few or none were detected while afloat and the evil became so extensive. It was frequently the practice of these River Pirates to go armed, and in sufficient force to resist, and even to act offensively if they met with opposition.--Their depredations were extensive among craft wherever valuable goods were to be found; but they diminished in number after the commencement of the war; and now since the establishment of the Marine Police they have almost totally disappeared. On the return of peace, however, if a system of watchful energy is not maintained, these miscreants must be expected (as on former occasions on the termination of wars) to renew their iniquitous depredations in great force, as numbers of depraved characters may then be expected to be discharged from the Army and Navy. 2d. _Night Plunderers._--These were composed chiefly of the most depraved class of watermen, who associated together in gangs of four or five in number, for the purpose of committing depredations on the cargoes of lighters and other craft employed in conveying goods to the quays and wharfs. Their practice was to associate themselves with one or more of the watchmen who were employed to guard these lighters while cargoes were on board, and by the connivance of these faithless guardians of the night, to convey away in lug boats every portable article of merchandize, to which, through this medium, they often had too easy access.
