\section{Method}  \textit{Eucalyptus bosistoana} was planted as seedlings into 100 (check this) L planting bags at an irrigated nursery site in Harewood, Christchurch, New Zealand. Two separate plantings occurred in 2010, and in 2012 (months?) The 2010 plant genetics originated from south east Australia and was were  harvested and coppiced in 2012 and harvested again in December 2014. The 2012 block planting  genetics originated from higher altitudes in New South Wales and was harvested in 2013 (at one year old, data not used due to the magnitude of errors induced by small melformed stems) and again October 2015 (at age two). When harvested each sample was processed for growth strain, volumetric shrinkage (displacment method, before and after drying), stem diameter (digital calipers), basic density (mass and displacment method) and dry acoustic velocity (resonance from WoodSpec --ref--). Growth strain was measured using a modified version of --kens refs-- method. The newly devaloped "rapid splitting test" substantually reduces measurment time enabling larger numbers of samples to be processed. The new method involves stripping the bark and measuring the underbark big end diameter of a clear section of the stem, giving an over estimate of the average diameter used by --ref--. The slit length is determened by the length of clear wood and diameter of the sample, measured, recored and cut, the error induced has been examined by --ref--. The small end of the sample is left intact with the large end free to distort, (removing the need to clamp the two halves togeather) the opening is measured and recored. The calculation of strain is uncheanged (with the exeption that average radious is now big end radious) from --ref-- and calculated using equation --crossref--. It is important to note that the over estimate of radious slightly reduces the strain value, but does so linearly over all samples.
