BULLETIN 1374, TJ. S. DEPARTMENT OP AGRICULTURE 
bolls had to be taken into consideration in the counts that year. 
Frost in 1922, however, did not occur till December 19, and at the 
time the counts were made that season many nearly mature green 
bolls were still on the plants. These bolls were recorded at the same 
time the counts were made, and in this way the figure for " Percentage 
of crop open" was obtained. The percentage of nonpickable cotton, 
however, is based on open bolls only. Had the counts been post- 
poned until after the frost, the amount of nonpicakble cotton would 
have been greater, for many of the green bolls would have had time 
to open, and they were all heavily infested. This would not have 
been comparable with 1921, on account of the lateness of frost. As 
it was, the results for irrigated cotton are more nearly comparable 
for the two years, since those in 1922 were made not very long after 
the time of the year when frost occurred in 1921. The extremely 
low figure for the unirrigated cotton in 1922 can be partly explained 
by the earliness of the counts. Had these been made at the end of 
October the percentage nonpickable would have more nearly ap- 
proached that of the unirrigated fields in 1921.

Average nonpickable, all classes, 1921, 12.8 per cent: 1922, 7.97 per cent. 
The great variations shown in the nonpickable cotton on different 
ranches are due to several things and will be taken up later. One
