The bat is made of wood, usually salix alba (white willow), and has the shape of a blade topped by a cylindrical handle. The blade must not be more than four and one quarter inches (108 mm) wide and the total length of the bat not more than 38 inches (965 mm). There is no standard for the weight, which is usually between 2 lb 7 oz and 3 lb (1.1 and 1.4 kg).
The 19th century saw underarm bowling superseded by first roundarm and then overarm bowling. Both developments were controversial. Organisation of the game at county level led to the creation of the county clubs, starting with Sussex in 1839. In December 1889, the eight leading county clubs formed the official County Championship, which began in 1890.
The wicket-keeper (sometimes called simply the "keeper") is a specialist fielder subject to various rules within the Laws about his equipment and demeanour. He is the only member of the fielding side who can effect a stumping and is the only one permitted to wear gloves and external leg guards. Depending on their primary skills, the other ten players in the team tend to be classified as specialist batsmen or specialist bowlers. Generally, a team will include five or six specialist batsmen and four or five specialist bowlers, plus the wicket-keeper.
Crickets have from time to time appeared in poetry. William Wordsworth's 1805 poem The Cottager to Her Infant includes the couplet "The kitten sleeps upon the hearth, The crickets long have ceased their mirth". John Keats's 1819 poem Ode to Autumn includes the lines "Hedge-crickets sing; and now with treble soft / The redbreast whistles from a garden-croft". The Chinese Tang dynasty poet Du Fu (712–770) wrote a poem that in the translation by J. P. Seaton begins "House cricket ... Trifling thing. And yet how his mournful song moves us. Out in the grass his cry was a tremble, But now, he trills beneath our bed, to share his sorrow."
The game underwent major development in the 18th century to become England's national sport. Its success was underwritten by the twin necessities of patronage and betting. Cricket was prominent in London as early as 1707 and, in the middle years of the century, large crowds flocked to matches on the Artillery Ground in Finsbury. The single wicket form of the sport attracted huge crowds and wagers to match, its popularity peaking in the 1748 season. Bowling underwent an evolution around 1760 when bowlers began to pitch the ball instead of rolling or skimming it towards the batsman. This caused a revolution in bat design because, to deal with the bouncing ball, it was necessary to introduce the modern straight bat in place of the old "hockey stick" shape.
Previous versions of the Spirit identified actions that were deemed contrary (for example, appealing knowing that the batsman is not out) but all specifics are now covered in the Laws of Cricket, the relevant governing playing regulations and disciplinary codes, or left to the judgement of the umpires, captains, their clubs and governing bodies. The terse expression of the Spirit of Cricket now avoids the diversity of cultural conventions that exist in the detail of sportsmanship – or its absence.
Crickets feature as major characters in novels and children's books. Charles Dickens's 1845 novella The Cricket on the Hearth, divided into sections called "Chirps", tells the story of a cricket which chirps on the hearth and acts as a guardian angel to a family. Carlo Collodi's 1883 children's book "Le avventure di Pinocchio" (The Adventures of Pinocchio) featured "Il Grillo Parlante" (The Talking Cricket) as one of its characters. George Selden's 1960 children's book The Cricket in Times Square tells the story of Chester the cricket from Connecticut who joins a family and their other animals, and is taken to see Times Square in New York. The story, which won the Newbery Honor, came to Selden on hearing a real cricket chirp in Times Square.
