The Sami people of Arctic Scandinavia (shown here in a print of c1800) have one thousand words for their reindeer and more than one hundred and eighty for snow and ice, figures that emphasize how important those things are in their lives. 
When I was researching for Regency Slang Revealed I found twenty seven words or phrases relating to the crime of pickpocking which suggests that while it might not have filled the thoughts of people in 1800 to quite the same extent, it was a significant crime and one that was encountered on a regular basis.
To go pick-pocketing, or to practice the Figging Law (the art of picking pockets) was to go on the Buz Gloak, to File the Cly or to Dive, Draw, Foist or Shake. There were categories of pickpocket. A Knuckles was a superior practitioner and a Rum Diver was particularly dexterous while a Fork used his middle and forefingers to delve into pockets. A pick pocket who was constantly at work was said to keep his Fives A-Going.
Pickpockets generally were Buzmen, Cly Fakers, Divers, Dummee Hunters, Files or Foists. Very often they worked in groups – Bulk and File – or had associates who would run off with the stolen goods the moment they were taken – the Adam Tylers. A female pickpocket might well wear a Round-about, a large circular pocket worn under her skirts in which to stash her ill-gotten gains.
Prostitutes often acted as decoys for pickpockets and a man whose mind was anywhere but on the contents of his pockets might well find them empty after an encounter in a back alleyway. But even the most virtuous were in danger – Autem Divers operated in churches, picking the pockets of worshippers whose concentration was on higher things. An Anabaptist, however, was not a follower of that religious sect but a pick pocket who had been caught and suffered summary punishment with a ducking in the nearest pond or under the pump. In a detail from an Alken print of a race meeting (at the head of this post) the man in a blue coat is picking the pocket of another who is totally distracted by a game of dice.
Stealing handkerchiefs (Clouts or Wipers) was a particular specialty. Unlike the paper tissues of today, costing virtually nothing and instantly discarded, a handkerchief in the Georgian period was a large piece of fabric, often good linen (a Kent), fine cotton lawn (a Lawn) or silk (a Sleek Wipe, India Wipe or Fogle), and worth money. Stealing them was to go on the Clouting Lay and a Fogle, Napkin Hunter or Wipe Drawer was the specialist in this form of crime.
Gentlemen often kept their handkerchiefs in a pocket in the tails of their coats which preserved the line of the body of the coat but made the handkerchief vulnerable. Sometimes they were deliberately displayed coming out of the back pocket to perhaps show off a fine Belcher (spotted silk handkerchief) – and that was asking for trouble. The two lads in the print by Alken seem to be stealing just such a handkerchief, one distracting the mark by begging, the other taking the handkerchief.
In no time at all a stolen handkerchief would be in the hands of of a Ferret (pawnbroker) or for sale in a Bow-Wow, a secondhand clothes shop.
Theft of an article worth more than one shilling was a crime punishable by death until 1823, although juries frequently assessed stolen goods at under that value in order to save the accused from the gallows. Stealing handkerchiefs was probably a profitable form of larceny that kept the Buzmen just on the right side of that line, although they could well face transportation and/or a vicious flogging. One pickpocket who did not do too badly, despite being caught, was George Barrington, known as ‘the pickpocket of gentleman and the gentleman of pickpockets.’ He was transported to Botany Bay in 1791. By 1796 he was the Superintendent of Convicts, and later, High Constable.
The final print, of the famous street entertainer Black Billy performing in front of the statue of Charles I, shows another handkerchief being stolen on the extreme right of the picture. The pickpocket is a most respectable-looking youth – it seems you couldn’t trust anyone!

Fascinating stuff, Louise. Thank you. I knew some but nowhere all of these. And your prints are fantastic.
Thank you, Joanna!
Excellent article. Many thanks.
