(d) Dirty peanuts where the surface is distinctly dirty and the dirt 
ground in. This condition usually results when peanuts are rubbed 
in the machinery in the process of handling. 
(e) Wormy or worm -injured peanuts. Peanuts which show only slight 
and superficial worm injury with no frass around the injury shall not 
be considered as damaged. 
(J) Peanuts shall not be considered as damaged which show a light yellow 
color or a slight yellow pitting of the flesh. 
6. " Noticeably discolored skins." Peanuts which show dark brown discol- 
oration, usually netted and irregular, affecting more than 25 per cent of the 
skin, shall be classed as noticeably discolored. Peanuts which are paler or 
darker in color than is usually characteristic of the variety, but which are not 
actually discolored, shall not be classed as noticeably discolored. 
7. "Badly discolored skins." Peanuts which show bluish or black discolora- 
tion, affecting an area in excess of one-half the surface in the aggregate, shall be 
classed as badly discolored. 
Actual screening of numerous samples of peanuts, taken from 
many different shipments, has shown that in years of ordinary crop 
conditions most commercially acceptable lots of Spanish peanuts 
come within the above grades. If reasonable care is exercised in 
running the peanut-shelling and screening machinery at proper speed, 
and in picking out undesirable material as the shelled product passes 
along the picking tables, shellers will have little difficulty in meeting 
the requirements of the Federal grades. Figure 16 shows samples of 
U. S. No. 1 and U. S. No. 2 taken from commercial lots that are 
superior to the minimum, requirements of these grades. 
The grades met with immediate commendation from many large 
shelling interests in the Southeast. They have been adopted by the 
Southeastern Peanut Association and the majority of the sales of 
shelled Spanish in the United States are now made on the basis of 
these grades. 
The increasing use of shelled Kunners as a substitute for shelled 
Virginias in making peanut butter and peanut candy resulted in 
many requests for United States grades for Kunners. Accordingly, 
after a careful investigation the Bureau of Agricultural Economics 
of the Department of Agriculture, offered on January 8, 1925, 
United States grades for shelled Runner peanuts. These grades, 
revised to September 1, 1925, 13 follow: 
U. S. No. 1 shall consist of shelled Runner peanuts which are whole and free 
from small shriveled, unshelled or damaged peanuts and from foreign material. 
In order to allow for variations incident to proper grading and handling, not 
more than 1 per cent, by weight, may consist of other varieties of peanuts; 
not more than 3 per cent, by weight, of split or broken kernels; not more than 2 
per cent, by weight, of small shriveled peanuts; not more than Vyi per cent, by 
weight, of unshelled or damaged peanuts; and not more than 34 per cent, by 
weight, of foreign material. 
U. S. No. 2 shall consist of shelled Runner peanuts which may be split or 
broken, but which are free from small shriveled, unshelled, or damaged peanuts, 
small pieces of peanuts, and from foreign material. 
In order to allow for variations incident to proper grading and handling, not 
more than 1 per cent, by weight, may consist of other varieties; not more than 6 
per cent, by weight, of small pieces of peanuts or small shriveled peanuts; not 
more than 1^ per cent, by weight, of unshelled or damaged peanuts; and not 
more than 34 per cent, by weight, of foreign material. 
The definitions of grade terms agree exactly with those given for 
shelled Spanish, except that discolored skins are not mentioned. 
Figure 17 shows samples of U. S. No. 1 and U. S. No. 2 grades of 
shelled Runners.
