wools. Due to a wide range in the quality of carpet wools and the wide range of the
density in packing, it is doubtful whether the core sample will be able to represent
any consignment. However, this difficulty can be overcome by conducting a
preliminary investigation in the method of sampling and a final solution worked out
to help to evolve a suitable method for handling carpet wools. There is a lot of
talk in the international wool trade about the uncertainty of the quality standards
of carpet wools exported from India and in order to create confidence in the foreign
buyers it seems that this method may be given a trial before long.
