and the effects of its use upon the condition of the cotton are 
described later. 
It was noted at some gins that the lint was carried by hand from 
the gin stand to the press box. while in others it was pushed on rough 
floors to the press. Where carried by hand, the lint was often rolled 
into a bundle so that it became tangled. The lint pushed on the 
rough floors was rolled and twisted, and the grade often was thus 
lowered.

Another factor that affected the grade was the casings, or housing, 
of the gin stand. In some gin plants they were so badly adjusted 
that occasional locks of seed cotton slipped around the ends of the 
rollers and became mixed with the ginned cotton. Others had de- 
fective casings which allowed some of the ginned seeds to be mixed 
with the lint and passed into the bales. 
With such a variety of ginning methods and differences in con- 
struction and handling of the gins it is inevitable that there should 
be a diversity in the appearance and condition of the cotton in the
