A STUDY OF WHEAT. 



brought a lighted lantern or a flame of any kind in contact with the 

 mixture, who can say what would be the result? 



Certainly the subject is well worth experimenting with, and the 

 miller is in a much better position to do this than the scientist, for 

 he is acquainted with all the practical workings of the mill, 

 and familiar with all the questions of mill explosions. 



2. The middle fruit-coat, or mesocarp as called by botan- 

 istsis made up 1 of several layers of longitudinally extended 

 cells, similar in appearance to the first coat, only not beaded

so strongly. The walls are more delicate, cells a trifle wider 

 and closely adherent to each other and to the epidermis. It 

 is almost impossible to separate these two coats without the 

 aid of re-agents. 



3. The inner fruit-coat or endocarp is composed of long, 

 narrow cells similar to those of the first coat, only lying at 

 right angles to them, that is, the longest way of the cells lies 

 cross-ways of the grain. (See Fig. 3.) They are from 1-150 

 to 1-300 of an inch in length. The walls are more finely 

 beaded, presenting a stronger appearance than in the outer 

 fruit-coat. It is almost impossible to mistake any of these coats
