The stink-pot is an earthenware vessel filled with powder, sulphur, &c. Each junk had cages at the mast-head, which in action were occupied by one or more men, whose duty it was to throw these stinkpots on to the decks of the enemy, or into boats attempting to board; and woe betide any unlucky boat that received one of these missiles: the crew would certainly have to jump overboard or be stifled.
Describing the method of use of the stinkpot, Kennedy writes:
One man ascends the foremast, and one the mizzenmast, all going to the very top and remaining on the highest yard. Two men stand at the foot of each mast and haul up the baskets containing the stink-pots by means of a pulley. Each basket contains ten or more stink-pots, and every pot has 4-pounder rolls enclosed in cotton cases. These being drawn up briskly, the men at the mast-head then apply the matches, when they are instantaneously discharged. When one basket is emptied, another is hauled up, so as to keep up an uninterrupted delivery on board the barbarian ship.
