284 AGRICULTURAL CHEMISTRY 



Rejected spring wheat shall include all spring wheat grown badly 

 bleached, or for any other cause unfit for No. 3 wheat. 



Note. Wheat containing admixture of "rice" or "goose" wheat 

 will in no case grade better than rejected. 



" No grade" wheat. All spring wheat that is in a heating condi- 

 tion, too musty or too damp to be safe for warehousing, or that is 

 badly bin-burnt, badly damaged, exceedingly dirty, or otherwise 

 unfit for storage shall be classed as "no grade' ' with inspector's nota- 

 tion as to quality and condition. 



Note. The amount of dirt in all wheat shall be determined by 

 the inspectors. 



No. i white winter shall be sound, well cleaned, reasonably 

 plump, and composed of the white varieties. 



No. i winter to be sound, well cleaned, reasonably plump, and 

 composed of the mixed white and red winter. 



No. 2 winter to be sound, reasonably clean, and composed of the 

 mixed white and red winter. 



No. 3 winter shall comprise all winter wheat fit for warehousing, 

 weighing not less than 54 pounds to the measured bushel, not sound 

 enough or otherwise unfit for No. 2 of the other grades. 



Rejected winter, fit for warehousing but otherwise unfit for No. 3. 



386. Composition of Unsound Wheat. When wheat 

 fails to fully mature or is affected by frost, fungus dis- 

 ease, as rust or smut, or excessive heat causing bleach- 

 ing, the composition of the kernel is affected. Such 

 wheats usually contain a larger percentage of soluble car- 

 bohydrates, organic acids, and soluble proteids than fully 

 matured wheat. Generally, the percentage amount of 

 protein is higher although sometimes it is lower than in 

 normal wheat. Wheat which has been damaged by 

 bleaching, frost or fungus disease gives a lower yield of 

 flour with poorer keeping and bread-making qualities.
