These corrupt watchmen did not always permit the lighters under their own charge to be pillaged.—Their general practice was, to point out to the leader of the gang those lighters that were without any guard, and lay near their own, and which, on this account, might be easily plundered. An hour was fixed on for effecting the object in view. The Receiver (generally a man of some property) was applied to, to be in readiness at a certain hour before day-light to warehouse the goods. A lug boat was seized on for the purpose. The articles were removed into it out of the lighter, and conveyed to a landing-place nearest the warehouse of deposit. The watchmen in the streets leading to this warehouse were bribed to connive at the villainy, often under pretence that it was a smuggling transaction, and thus the object was effected.

In this precise manner was a quantity of ashes and hemp conveyed in 1798, to the house of an opulent Receiver. Several other cargoes of hemp, obtained in the same manner, were conveyed up the river, and afterwards carted in the day-time to the repositories of the purchaser, till by the vigilance of the Police Boats, a detection took place, and the whole scene of mischief was laid open.

This species of depredation went to a great extent, and when it was considered that the very men who Were appointed to guard property in this situation were themselves associates in the criminality, and participated in the profit arising from the booty; and that matters were so arranged as to secure the connivance of all those who were appointed to situations with a view to detect and apprehend delinquents; it ceases to be a matter of wonder, that the plunder in this particular line was excessive.

In many instances where goods could not be plundered through the connivance of watchmen, it was no uncommon thing to cut lighters adrift, and to follow them to a situation calculated to elude discovery where the pillage commenced. In this manner have whole lighter loads even of coals been discharged at obscure landing places upon the river, and carted away during the night.

Even the article of Tallow from Russia, which, from the unwieldiness of the packages, appears little liable to be an object of plunder, has not escaped the notice of these offenders: large quantities have been stolen, and an instance has been stated to the Author, where a lighter loaded with this article was cut from a ship in the Pool, and found next morning with six large casks of tallow stolen, and two more broken open, and the chief part plundered and carried away. In short, while the river remained unprotected nothing escaped these marauders.

3d. Light-Horsemen, or Nightly Plunderers of West India ships.—This class of depredators for a long period of time had carried on their nefarious practices with impunity, and to an extent in point of value, that almost exceeds credibility; by which the West India planters and merchants sustained very serious and extensive losses.

The practice seems to have originated in a connection which was formed between the Mates of West India ships[55] and the criminal Receivers, residing near the river, who were accustomed to assail them under the pretence of purchasing what is called sweepings, or in other words, the spillings or drainings of sugars, which remained in the hold and between the decks after the cargo was discharged. These sweepings were claimed as a perquisite by a certain proportion of the Mates, contrary to the repeated and express rules established by the Committee of Merchants, who early saw the evils to which such indulgences would lead, and in vain attempted to prevent it. The connivance, however, of the Revenue officers became necessary to get these sweepings on shore, and the quantity of spillings were gradually increased year after year by fraudulent means, for the purpose of satisfying the rapacity of all whose assistance and collusion was found necessary to obtain the object in view.

The connection thus formed, and the necessary facilities obtained, from the sale of sweepings, recourse was at length had to the disposal of as much of the cargo as could be obtained by a licence to nightly plunderers, composed of Receivers, Coopers, Watermen, and Aquatic Labourers, who having made a previous agreement with the Mate and Revenue Officers, were permitted, on paying from thirty to fifty guineas, to come on board in the night,—to open as many hogsheads of sugar as were accessible,—and to plunder without controul. For this purpose, a certain number of bags dyed black, and which went under the appellation of Black Strap, were provided.—The Receivers, Coopers, Watermen, and Lumpers, went on board at the appointed time, for all these classes were necessary. The hogsheads of sugar and packages of coffee, &c. were opened; the black bags were filled with the utmost expedition and carried to the Receivers, and again returned to be refilled until daylight, or the approach of it, stopped the pillage for a few hours. On the succeeding night the depredations were again renewed; and thus, on many occasions, from fifteen to twenty hogsheads of sugar and a large quantity of coffee, and also in some instances rum (which was removed by means of a small pump called a Jigger, and filled into bladders with nozzels,) were plundered in a single ship, in addition to the excessive depredations which were committed in the same ships by the Lumpers or labourers who were employed during the day in the discharge of the cargo.—Instances have been adduced, and judicially proved, of various specific ships having been plundered in an excessive degree in this manner; and it has been estimated upon credible authority, that previous to the establishment of the Marine Police, above one-fifth of the whole fleet suffered by nightly plunder.—The ships subject to this species of depredation were generally known from the characters of the Mates or Revenue Officers who were on board, and were denominated Game Ships, where the aquatic labourers, called Lumpers, would on every occasion agree to work without wages, and even solicit their employers to be preferred on these terms, trusting to a general licence to plunder for their remuneration.

This nefarious traffic had long been reduced to a regular system. The mode of negociation necessary to obtain all the requisite advantages for carrying into execution these iniquitous designs, was not only perfectly understood, but in most cases, where new Officers were to be practised upon, a plan of seduction was resorted to which seldom failed to succeed, when one or more of the old practitioners in this species of criminality happened to be stationed in the ship.—In this particular line of aquatic depredations, (which certainly was the most mischievous,) scenes of iniquity have been developed, which, from their extent and magnitude, could not have been credited had they stood on any other foundation than that of regular judicial proofs.

4th.—Heavy Horsemen, otherwise denominated Lumpers of the most criminal class, who generally selected ships where plunder was most accessible, either from the criminal connivance of the Mates and Revenue Officers, in permitting nightly plunder, or from the carelessness or inattention of these Officers.
