The following table shows the amount produced annually

Says Dr. Bruckner: "The sold and liquid excretions 

 taken together, will show the following annual value : '

 every pound of the urine of a horse or man, will furnish 

 sufficient ammonia for a pound of wheat; and two and a 

 half pounds of the urine of man will furnish the phospho- 

 ric acid, and more than half of the potash required for a 

 pound of wheat." 



It then remains for us to make the application of these 

 remarks, and every right-thinking man will see at once the 

 importance of gathering up and saving. It is money in his 

 pocket. One man will burn a few bushels of soil, and set-
