Commission Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BLEACHING YARN, WARPS, OR SIMILAR MATERIALS," to be as
follows:-
I pass the yarn or warps, previous to being sized, through a weak solution
of chloride of lime, or chloride of soda, or other bleaching agent, and then

then pass it through rollers in water to wash off the lime, soda, or other agent,
and the yarn is ready for sizing.
