The data is from a dew-retting experiment in Ballarat 1942-43, in which flax was laid out under various climactic conditions and for various periods. Retting involves softening the flax stems by soaking in water, thus enabling the separation of the linen fibres from the wooden material by a process called scrutching. The flax variety used was "Liral Crown". Two samples were taken from each trial and the ret loss, as a percentage, was calculated. The other three variables are the mean daily rainfall (in points), the retting period (in days) and the mean daily temperature (in degrees Farenheit).
