On an average you will find that a feed rich in one ingredient will 

 be poor in all the others. It is the same with men. We cannot hold 

 more than just so much. If rich in one thing, we will be deficient in 

 the others. Therefore it stands to reason that if the feeds we grow are 

 deficient in protein, we must buy it. This chart shows that those pro- 

 ducts that are high in water are low in the otlier elements. 



Here on chart No. 8, you will see the average amount of nitrogen 

 free extract in the feeding stuffs.

Now, I notice the time is going fast, and I will simply call your at- 

 tention to this last chart, in order that we may have time for discus- 

 sion.
