CLASSES OF COMMEECIAL FEEDS— Continued 

 Corn Chops, as found on the American market, are the cracked 

 grains of corn. Some of this feed is made up of inferior corn 

 and sometimes may contain ground corn cobs. To be of good 

 standard quality this feed should contain 9 per cent, protein, 

 should be free from fermentation and adulteration, should smell 

 sweet and look clean, and be made from sound grains of corn. 

 A close physical examination will reveal the quality of this 

 material to a great extent.

Mixed Oats and Barley. — On account of the high price of oats, 

 barley (which is cheaper and heavier) is often mixed with oats 

 and sold as No. 2 oats or as mixed oats and barley. Much 

 of this class of goods is made of inferior oats, S to 40 per cent, 

 of barley, and sometimes contains weed seeds. The barley grain 

 is smaller than the oat grain and can be easily detected. The 

 ofif grade oats may be distinguished by their color or .their 

 shrunken or shriveled appearance. The presence of weed seeds 

 is easily noticed.
