CONTROL BULLETIN No. 104 



Cracked corn and foreign material consists of small pieces of corn and 

 material other than corn. A high cracked-corn content might conceivably result 

 where corn was immature, with a high water content, and had been artificially 

 dried, resulting in a soft brittle product easily broken in handling. 



Damaged kernels are defined as kernels or pieces of kernels of corn which are 

 heat damaged, sprouted, frosted, badly ground damaged, badly weather damaged 

 or otherwise materially damaged, all of which can be attributed to poor condition 

 of the grain at the outset or to poor handling. For No. 2 corn only 0.2 per cent 

 of heat damage is allowed. A small percentage of dark-colored kernels in corn not 

 only is an offense to the eye, but may indicate an unsatisfactory condition which 

 will gradually grow worse. 



Oats 



A point not generally understood by the average purchaser is the large number 

 of divisions and subdivisions of Federal grades of oats and oat-like material in 

 some of which cultivated oats does not even predominate. 



Oats "shall be any grain which consists of 80 per cent or more of cultivated 

 oats. Oats may contain not more than 10 per cent of wild oats." At their worst 

 oats might contain the following and still be properly designated as Grade 4.

Feed Oats "shall be any grain which consists of either (a) 30 per cent or more, 

 but less than 80 per cent of cultivated oats, but not less than 65 per cent of cul- 

 tivated and wild oats combined, or (b) 80 per cent or more of cultivated oats 

 oats and more than 10 per cent of wild oats. Feed oats may contain not more 

 than 25 per cent of other grains and may contain not more than 10 per cent 

 of foreign material which 10 per cent may include not more than 5 per cent of 

 fine seeds." The poorest grade of feed oats might conceivably contain the follow- 

 ing: 



Mixed Feed Oats "shall he any grain which consists of less than 30 per cent 

 of cultivated oats, but either (a) not less than 65 per cent cultivated and wild 

 oats combined, or (b) not less than 65 per cent of wild oats; may contain not 

 more than 25 per cent of other grains; and may contain not more than 10 per 

 cent of foreign material, which 10 per cent may include not more than 5 per cent 

 of fine seed." A poor grade of mixed feed oats might contain:
