This chart confirms the teachings of the lecturer this 

 morning, — that in dairy farming it pays to look after the 

 liquid voidings of the animals, because often the liquid 

 voidings contain the largest portion of valuable constituents 

 of food plants. This chart is used merely to show you that by 

 raising these crops and putting them with corn you get the 

 manure put back on the land again, and renew the fertilit3^ 



I have spoken of using, as far as we could, some plant that 

 will entangle the nitrogen, and give us the albuminoids re- 

 quired for feeding cows at the lowest possible cost to our- 

 selves ; and I have put on the next chart the nutrients per 

 acre that can be obtained from certain crops which I think
