After transportation by rail or road to the woolbroker's store, each wool bale's brand is carefully inspected to see that it corresponds with the classer's report. It is then weighed by sworn weighers (this weight is marked on the bale and recorded and is the basis on which buyers are invoiced), and then core sampled. This sample will then be tested for micron, yield and vegetable matter as a minimum. Wool that is to be sold by sample has a minimum of one grab, of a specified weight, taken from each bale and a minimum of 20 grabs, from each lot. Speciality wool is often traditionally displayed in original wool bales with the test results displayed. Wool not sold by the traditional display system will be directed to various parts in the warehouse for stacking and storing. An index is maintained showing the location of all bales so that, when their turn of offering-which is based on the equitable method of order of receipt into store approaches, they may be easily found.
