While the gangs afloat in this way lent their aid in the suppression of smuggling, they themselves were sometimes subjected to disagreeable espionage on the part of those whose duty it was to keep a special lookout for runners of contraband goods. An amusing instance of this once occurred in the Downs. The commanding officer of H.M.S. _Orford_, discovering his complement to be short, sent one of his lieutenants, Richardson by name, in quest of men to make up the deficiency. In the course of his visits from ship to ship there somehow found their way into the lieutenant's boat a fifteen-gallon keg of rum and ten bottles of white wine. Between seven and eight o'clock in the evening he boarded an Indiaman and went below with the master. Scarcely had he done so, however, when an uproar alongside brought him hurriedly on deck--to find his boat full of strange faces. A Customs cutter, in some unaccountable way getting wind of what was in the boat, had unexpectedly "clapt them aboard," collared the man-o'-war's-men for a set of rascally smugglers, and confiscated the unexplainable rum and wine, becoming so fuddled on the latter, which they lost no time in consigning to bond, that one of their number fell into the sea and was with difficulty fished out by Richardson's disgusted gangsmen. [Footnote: _Admiralty Records_ 1. 1473--Capt. Brown, 30 July 1727, and enclosures.] The only inward-bound ship the gangsmen were forbidden to press from was the "sick ship" or vessel undergoing quarantine because of the presence, or the suspected presence, on board of her of some "catching" disease, and more particularly of that terrible scourge the plague. Dread of the plague in those days rode the country like a nightmare, and just as the earliest quarantine precautions had their origin in that fact, so those precautions were never more rigorously enforced than in the case of ships trading to countries known to be subject to plague or reported to be in the grip of it. The Levantine trader suffered most severely in this respect. In 1721 two vessels from Cyprus, where plague was then prevalent, were burned to the water's edge by order of the authorities, and as late as 1800 two others from Morocco, suspected of carrying the dread disease in the hides composing their cargo, were scuttled and sent to the bottom at the Nore. This was quarantine _in excelsis_. Ordinary preventive measures went no further than the withdrawal of "pratique," as communication with the shore was called, for a period varying usually from ten to sixty-five days, and during this period no gang was allowed to board the ship.
