The picture on the right, which appeared as the frontispiece to an 1829 edition of Scott's Tales of a Grandfather shows Scott's grandson, John Hugh Lockhart with a clacken and ball at Abbotsford. This is probably the oldest representation of the clacken.
The design of the clacken, as described in the Encyclopaedia of Sport in 1898 as "a piece of wood about 18 inches long and has a head about 4 inches wide and ½ inch thick; just short of the head, the bat is thinned down to about ¼ inch from back to front, and again the head is thinned off towards the tip to make it easier to raise the ball from the ground."
The clacken was used in the game of Hailes, though it had other uses. "All would be armed with clackans, wooden bats suitable for playing shinty, or hails or hitting other boys' heads" (from E. S. Haldane's Scotland of our Fathers, 1933). In recent years it survives only at the Edinburgh Academy, where it is used in an annual Hailes match of the Ephors versus the Leavers (or non-Ephors) and in athletics where they run a clacken-and-ball race. Until the 1960s, it was still used in the Junior School for playing Hailes and also in the Senior School by the Ephors as a means of delivering corporal punishment.
In his poems of 1804, W. Tarras tells in verse of such a game:
and
The game just about died out during the nineteenth century with the rise in interest in football. It is known to have survived only in the Royal High School and Edinburgh Academy.
In James Trotter's book on the Royal High School, published in 1911, the game is referred to as "the distinctively school game of Clacken, now alas extinct! Less than thirty years ago in the 1880s no High School boy considered his equipment complete unless the wooden clacken hung to his wrist as he went and came".
Though it was played in the Junior School of the Edinburgh Academy until the 1960s, it had by then long since died out in the Upper School as a regular activity. However, as part of the centenary celebrations of the school in 1924, the Seventh year took on the Ephors in an exhibition match and this is now an annual event occurring on the last Wednesday or Tuesday of the Summer Term and is now become quite a sceptical which the whole school turns out to watch.
Old records suggest that when the dules were fixed at a great distance apart (400 m or so), the winning team was the one that scored the first hail. After that, the game was over. Numbers playing on each team were not fixed and varied from place to place. It may have been that there was not even a requirement for the same number to play in each team.
Copies of the Edinburgh Academy Chronicle suggest that the rules of the game have changed over the years as well. Players made up rules to suit the environment. In one case, the 'goal' was a flat surface upon which the ball had to be slammed downwards using the clacken. In the Junior School version, goals similar to hockey goals were set up, though without a cross bar. In some cases, these could simply be a pile of coats. In these versions, due to the relatively short distance between the goals, a score would be kept.
The game as it is now played annually and uses the entire school front yards. The goals are now two white poles about 10ft wide and there is a set at either end of the yards, the tennis ball simply has to pass between the two poles for a team to score a point and who ever has the most points at the end wins the games. The games has two halfs of about 10 minutes each. As it is a 'celebrity'( sixth and seventh year leavers only) game, there is a lot of off-the-ball fun as well. All players wear fancy dress and the use of water pistols and water balloons is not ruled out.
