Following this discovery a marketing organization was included in the Wool Improvement
Scheme to conduct experiments on shearing, garding, collection and sale of wool on a large scale,
along with other developmental activities, to work on Pattanwadi sheep in northern Gujerat to
start with. The number of sheep dealt with by this section rose from 11,000 in the first year to 65,000
in the third year. The Australian system of grading was adopted as the model and skirting and
classing were carried out immediately after shearing at the shearing yard. Taking into consideration
both individual and regional variations in the wool quality of the sheep of the whole tract, it was
possible to form five distinct classes, ' super ', ' first ' and ' second ' in white and 'colour' and
'skirtings' in coloured wool.
There is doubt that the distinctness and uniformity within each grade depends much on the
efficiency of assers. To find out how far this was successful and in what directions the quality of.
each class and be controlled, systematic laboratory analysis was conducted of the two top grades
for two consecutive collections. The qualities of various types of cotton have been standardized
and agmarking has been introduced, but so far no such attempts have been made to classify wool.
This study explores the possibilities and suggests a method of such standardization and agmarking
of Indian wools and in particular Pattanwadi wools in Baroda State.
Samples were collected from four different corners of ten. bags selected at random of each quality
of two consecutive collections and each of these four samples was brought down to a few hundred
fibres by dividing and discarding and these four bunches of fibres were combined to form one sample
representing a bag and the ten samples representing the entire consignment of one quality. Table I
gives the results of analysis of these samples for the two collections.
