mechanical injury during the process of proper grad-, — 
ing, handling, and packing; or irregular-shaped navels 
when the opening is so wide, considering the size of 
the orange, and the navel growth so badly folded and 
ridged that it detracts seriously from the appearance 
of the orange. 
(j) Spray burn, when seriously affecting appear- 
ance of the fruit or when more than 14% inches in 
diameter in the aggregate. 
(kK) Sunburn, when the affected portion exceeds 
one third of the fruit surface, or is hard or discolored, 
or the fruit decidedly one-sided. 
(Ll) Thorn scratches, when the injury is not well 
healed, or when light colored and concentrated and 
more than 1% inches in diameter, or black or scat- 
tered thorn injury which detracts from the appear- 
ance of the fruit to a greater extent than the 1144-inch 
light-colored concentrated injury. 
(m) Undeveloped or sunken segments, in navel 
oranges, when such segments are so sunken or un- 
developed that they are readily noticeable. 
TOLERANCES FOR PRECEDING GRADES 
The tolerances specified for the various grades are 
placed on a container basis. However, any lot of fruit 
shall be considered as meeting the requirements of a 
specified grade if the entire lot averages within the 
tolerances specified, provided that no sample from 
the containers in any lot is found to exceed the fol- 
lowing amounts: 
For a specified tolerance of 10 percent or more, not 
more than one and one half times the tolerance Shall 
be allowed in any one package. 
For specified tolerances of 5 percent or less, not 
more than double the tolerance shall be allowed in 
any one package. 
In order to allow for variations incident to proper 
grading and handling in each of the foregoing grades, 
the following tolerances are provided as specified: 
US. Fancy.—Not more than 10 percent, by count, 
of the fruit in any container may be below the re- 
quirements of this grade but not more than one fourth 
of this tolerance, or 244 percent, shall be allowed for 
damage by black or unsightly discoloration, and not 
more than one twentieth of this tolerance or 0.5 per- 
cent, shall be allowed for decay at shipping point. 
In addition, a total tolerance of not more than 3 per- 
cent shall be allowed for decay en route or at destina-
