Suggestion: Have the students figure tihe values of the 

 fertilizer constituents in one ton of several feed stuffs, valuing 

 nitrogen at 17 cents a pound, and phosphoric acid and potash at 

 5 cents a pound. Have them observe the amount of fertility 

 removed from an acre of land by some of the popular crops 

 grown in the locality. Assume a few common rations fed to 

 different classes of live-stock in the locality and let the students 

 calculate the yearly values of the manure obtained.
