34 AMERICAN WHEAT AND CORN. 



2007. Second break. 



In this break the greater part of the endosperm is separated from the bran, and 

 is seen as large well-shapen middlings, together, of course, with some small 

 stuff and dust. 



2008. Chop from second break. 



This is chiefly endosperm, with somewhat less bran than the previous chop. 

 Whole germs and parts are numerous. The endosperm is of all sizes, but the 

 greater portion of large angular fragments. The bran includes portions of 

 all the outer coverings, while dusty matter and starch grains are quite abun- 

 dant. 



2009. Third break. 



The endosperm is so completely separated in this break that it only remains in 

 scattered patches upon the bran, and the embryous membrane is quite visible. 



2010. Chop from third break. 



The middling or particles of endosperm are much finer, and there is more dust. 

 Small portions of germ are plentiful. The brauny particles are similar in 

 nature to those in the last chop but smaller, and there is more dust of a 

 nitrogenous kind. 



2011. Fourth break. 



Only to be distinguished from No. 2009 by the slightly cleaner bran. 



2012. Chop from fourth break. 



Not very different in appearance from 2010, except that it is composed of more 

 finely divided particles. 



2013. Fifth break. 



Still cleaner bran than 2011. It still holds a very appreciable portion of endo- 

 sperm. 



2014. Chop from fifth break. 



is chop contains a great deal of branny matter, including pieces of epicarp, 

 endocarp, and embryous membrane. The endosperm is very fine and much 

 mixed with germ. Of course, in all these products, portions of the testa and 

 tegmen are present, but they are not easily seen except in careful prepara- 

 tions. 



2015. Sixth break. 



Barely distinguishable from bran. 



2016. Chop from sixth break. 



Very largely made up of small pieces of branny material and germs. The endo- 

 sperm which is present is very fine. 



2017. Bran. 



This is composed practically of epicarp, endocarp, and embryous membrane, the 

 cells of the latter having been very little disturbed. There is still a little 

 cuticle and endosperm left, but they have mostly disappeared in previous 

 operations. 



2018. Shorts. 



These are made up of all the different parts of the grain in rather a fine condi- 

 tion, some of the branny particles having endosperm still adherent to them. 



2019. Middlings, Uncleaned No. 1. 



These are the largest sized middlings, and consist in themselves of clean, angular 

 fragments of endosperm, but they are mixed with considerable shorts and 

 many whole and broken germs. They are the most impure of the five, and 

 an analysis will show this fact. 



2020. Middlings, Uncleaned No. 2. 



All the particles are finer than in the previous middlings, and less germ and bran 

 is present, which will produce a corresponding change in their chemical com- 

 position.
