45--THE VARIABILITY OF FARM LOTS OF AUSTRALIAN GREASY WOOL CONSIGNED FOR BULK-CLASSING.

A study is reported of the variability of yield and fineness measurements between core samples within 'unclassed' lots of Australian greasy wool. The lots taken as 'unclassed' are some consigned from the farm for bulk-classing. The variability is compared with that found in previous studies, for auction lots that had been classed. The results are discussed from the point of view of obtaining an adequate sample from lots of unclassed wool, and a comment is made on the effectiveness of wool-classing as it appears from the comparison.
