COCKERMOUTH, a borough-town in the ward of Alderdale, in Cumberland, twenty-five miles from Carlisle, and 302 from London. It stands near the confluence of the rivers Derwent and Cocker, and contains the remains of an ancient castle, which must have been of great strength. There are manufactures of leather, hats, shalloons, coarse woollens, and linens. The town is governed by a bailiff and a jury of sixteen burgesses. The principal market is held on Monday, and there is a smaller one on Saturday. The inhabitants amounted in 1801 to 2865, in 1811 to 2964, and in 1821 to 3790.
COCKET is a seal belonging to the king's custom-house, or rather a scroll of parchment sealed and delivered by the officers of the customs to merchants, as a warrant that their merchandise has been customed.
It is also used for the office where goods transported were first entered and paid their custom, and had a cocket or certificate of discharge.
